======================================================
Explanation:
Solve each inequality for x
[tex]5x \ge 20[/tex] solves to [tex]x \ge 4[/tex] after dividing both sides by 5
[tex]x+14 < 16[/tex] solves to [tex]x < 2[/tex] after subtracting 14 from both sides
The original system solves to [tex]x \ge 4 \ \text{ or } \ x < 2[/tex] which is the same as [tex]x < 2 \ \text{ or } \ x \ge 4[/tex]
So x is either less than 2, equal to 4, or larger than 4.
The graph that fits the description above is Choice B. We have an open hole at x = 2 to show we don't include this value. In contrast, there's a filled in hole or closed circle at x = 4 to include this value. The blue shaded region is the set of all possible x values, so we shade to the left of x = 2 and to the right of x = 4.
----------------------
Side note: I don't know why your teacher thought it was a good idea to make the answer choice tiles be larger than the actual problem itself. It should be the other way around. Though to be fair, it's probably a design choice that your teacher wasn't involved in.
30 term of AP 1,7,4 is
Correct Question
30th term of AP 10, 7, 4 is
Answer:
The 30th term is -77
Step-by-step explanation:
Required
Determine the 30th term of the given progression
First, we need to determine the common difference (d);
[tex]d = T_2 - T_1[/tex]
[tex]d = 7 - 10[/tex]
[tex]d = -3[/tex]
The nth term of an AP is calculated by
[tex]T_n = a+ (n -1) d[/tex]
In this case;
n = 30;
a = First term = 10
d = -2
Substitute these values in the given formula
[tex]T_{30} = 10+ (30 -1) * -3[/tex]
[tex]T_{30} = 10+ (29) * -3[/tex]
Open the bracket
[tex]T_{30} = 10-87[/tex]
[tex]T_{30} = -77[/tex]
Hence, the 30th term is -77

Answer:
hii
Step-by-step explanation:
how are you hope you are fine
Answer:
[tex] \boxed{ \huge{ \bold{ \sf{\boxed{ \: Rs \: 25425}}}}}[/tex]Step-by-step explanation:
Given,
Marked Price ( MP ) = Rs 25000
Vat percent = 13 %
Discount percent = 10 %
▪️Finding the discount amount
Discount amount = Discount % of MP
= 10 % of 25000
= Rs 2500
▪️Finding the Selling price
Selling price ( SP ) = MP - Discount amount
= Rs 25000 - Rs 2500
= Rs 22500
▪️Finding the Vat amount
Vat amount = Vat % of SP
= 13 % of 22500
= Rs 2925
▪️Finding the SP with VAT
SP with vat = SP + Vat amount
= Rs 22500 + Rs 2925
= Rs 25425

A 12" diameter ball rolls around inside the bottom of a rectanglar bow that is 14" wide and 30" long.The ball always touches the side of the box. Make a sketch of the ball in several positions. What is the shape of the path of the center of the ball? How ling is the path?
Answer:
1. Shape of line drawn by round ball is: Rectangle
2. Length of path round ball creates is: 64 inches
Step-by-step explanation:
The perimeter of the box is 30+30+14+14 = 88 inches.
We find a rectangle path of the round ball to be interior rectangle shape and measures 64 inches.
The shape of the path is rectangle, this is because when the balls direction from horizontal to vertical is drawn from the central line to the ball - the ball still rotates but such central line stays stationary in a straight line at same distance from edge as it changes direction so therefore it stays perpendicular and creates a rectangle shape. Only an oval ball would draw a line of oval shape due to its central line curving against the perpendicular edge of the rectangle. The round ball cannot create a square shape as the sides of the rectangle when reduced by 6'' + 6'' either side of length 30 = 18 inches and is still longer than the shorter sides of the box being 14'' which becomes 14- 6=8 inches to each side.
2. To find the path length- we look for the difference in width of the central ball first which is 12'' divided by 2 = 12/2 = 6 = 6 inches. We can then deduct this from 14'' and from 30'' then multiply by 2.
Width of one side = 14-6 = 8
= 8 inches
Length of one side = 30-6 = 24
= 24 inches
We add together 8+24 = 32, and then multiply by 2
32 *2 = 64

The density of a certain material is such that it weighs 46 grams for every 9 fluid ounces of volume. Express this density in ounces per liter. Round your answer to the nearest hundredth.
Answer:
The density of the material is approximately 6.79 ounces per litre
Step-by-step explanation:
We note that 1 fluid ounce = 26.5735 mililiter
The mass of the material for every 9 fluid ounces of volume = 46 grams
Therefore, the density of the material is given as follows;
Density = Mass/Volume = 46 grams/(9 × 26.5735 mililiter)
Density = 46 grams/(239.1615 mililiter)
1 gram = 0.035274 ounces
46 grams = 46 × 0.035274 ounces = 1.622602 ounces
1 mililiter = 0.001 litre
239.1615 mililiter = 0.2391615 litre
The density in ounces per liter is therefore;
Therefore;
The density of the material = 46 grams/(239.1615 mililiter) = 1.622602 ounces/0.2391615 litre
The density of the material ≈ 6.785 ounces/litre which is 6.79 ounces/litre to the nearest hundredth.
Answer: the correct answer is 6.10 ounces per liter
Step-by-step explanation:
10y + 9x = -9
10y + 5x= -5
x=
y=
Answer: x=-1 and y=0 .
Step-by-step explanation:
The given linear equations:
[tex]10y + 9x = -9\ ...(i)\\\\10y + 5x= -5\ ...(ii)[/tex]
Subtract (ii) from (i) , we get
[tex]10y+9x-(10y+5x)=-9-(-5)\\\\\Rightarrow\ 10y+9x-10y-5x=-9+5\\\\\Rightarrow\ 4x=-4\\\\\Rightarrow\ x=-1[/tex]
Put value of x in (i), we get
[tex]10y+9(-1)=-9\\\\\Rightarrow\ 10y-9=-9\\\\\Rightarrow\ 10y=-9+9=0\\\\\Rightarrow\ y=0[/tex]
Hence, x=-1 and y=0 .
On a highway a wreck occurred and caused an 8 mile traffic jam on one side of the road. The average car is 14.5 feet in length, the average truck is 21 feet in length, and the average 18 wheeler tractor trailer is 73 feet in length. 70% of the traffic jam consists of cars, 20% trucks, and 10% 18 wheeler tractor trailers. If the average distance between vehicles is 4 feet, how many vehicles are stuck in the traffic jam?
Answer:
1647
Step-by-step explanation:
Given the following information:
Length of traffic = 8 miles
Average Length of vehicles on the road :
Cars = 14.5 feets
Trucks = 21 feets
18 Wheeler tractor = 73 Feets
% distribution of the different vehicles :
Cars = 70% = 0.7
Trucks = 20% = 0.2
18 wheeler tractor = 10% = 0.1
Distance between vehicles = 4feets
Number of vehicles stuck in the traffic :
Let number of vehicles = v
Summation of (number of vehicles * length of each vehicle) + distance between each vehicle = Length of traffic
Total distance between each vehicle = 4(v-1)
(0.7v * 14.5) + (0.2v * 21) + (0.1v * 73) + 4(v - 1) = 8 miles
1 mile = 5280
8 miles = (5280 * 8) = 42,240
10.15v + 4.2v + 7.3v + 4v - 4 = 42240
25.65v = 42240 + 4
25.65v = 42244
v =42244 / 25.65
v = 1646.939
v = 1647.

What is the area, in square inches, of the isosceles trapezoid below?
17.9 in
18 in
8.3 in
Answer:
104.8 in^2
Step-by-step explanation:
There are 2 ways to solve this problem.
The 1st way:
Let's make 2 triangles and 1 rectangle:
Rectangle Length = 8.3
Rectangle Width = 8
So, the left out length will be 17.9 - 8.3
=> 9.6
Since, 9.6 cm is for 2 parts.
=> 9.6 / 2
=> 4.8
So, Height of the Triangle = 8
Base of the triangle = 4.8
Area of a rectangle
=> 8.3 x 8
=> 66.4
Area of the triangle
=> 1/2 x 8 x 4.8
=> 4 x 4.8
=> 19.2
There are 2 triangles:
=> 19.2 x 2
=> 38.4
=> 66.4 + 38.4
=> 104.8
The area of the trapezoid = 104.8 in^2.
The 2nd way is:
Area of a trapezoid
=> Smaller Base + Larger Base / 2 x Height
=> 8.3 + 17.9 / 2 x 8
=> 26.2 / 2 x 8
=> 13.1 x 8
=> 104.8
The area of the trapezoid is 104.8 in^2

solve -10=4x show work please :D
Answer:
-2.5 = x
Step-by-step explanation:
-10 = 4x
the equation between 4 and x is multiplication
as our goal is to move the x on its separate side, we should divide each side by 4 to get rid of the bond between the 4 and the x
Therefore,
-10 = 4x
-10/4 = x
Simplify into decimal if needed
-2.5 = x

Then, he wants to buy as many pancakes as he can, but he wants his bill to be at most $ 30 $30dollar sign, 30 before tax. The restaurant only sells pancakes in stacks of 4 44 pancakes for $ 5.50 $5.50dollar sign, 5, point, 50. Let S SS represent the number of stacks of pancakes that Benjamin buys. 1) Which inequality describes this scenario? Choose 1 answer: Choose 1 answer: (Choice A) A 3.25 + S ≤ 30 3.25+S≤303, point, 25, plus, S, is less than or equal to, 30 (Choice B) B 3.25 + S ≥ 30 3.25+S≥303, point, 25, plus, S, is greater than or equal to, 30 (Choice C) C 3.25 + 5.50 S ≤ 30 3.25+5.50S≤303, point, 25, plus, 5, point, 50, S, is less than or equal to, 30 (Choice D) D 3.25 + 5.50 S ≥ 30 3.25+5.50S≥303, point, 25, plus, 5, point, 50, S, is greater than or equal to, 30 2) What is the largest number of pancakes that Benjamin can afford? pancakes Show Calculator
Answer:
The correct option is;
C. 3.25 + 5.50·S ≤ 30
Step-by-step explanation:
The given parameters are;
The cost of the chocolate milk ordered = $3.25
The unit quantity of pancake sales = Stack
The number of pancakes in a stack = 4
The amount a stack of four pancakes is sold = $5.50
The number of pancakes Benjamin wants to buy = As many as he can
The number of stacks of pancakes Benjamin buys = S
The cost of the pancakes Benjamin buys = $5.5 × S
The cost of the number of pancakes Benjamin buys
The maximum amount Benjamin wants his bill to amount to = $30
Therefore we have;
The cost of chocolate milk ordered + The cost of pancakes Benjamin buys ≤ $30
Which gives;
$3.25 + $5.50 × S ≤ $30
Therefore, the correct option is 3.25 + 5.50·S ≤ 30.
Maximum variation sampling is: Multiple Choice the number of times a researcher will ask an individual to participate in a research project. based on informational redundancy; a researcher seeks participants until the data received are the same as previously collected data. a form of probability sampling. the degree to which the sample varies from the population on important characteristics. the number of variables included in the research design.

Maximum variation sampling is used;
When the purpose is to understand the view of diverse groups of people on a particular topic.
When the researcher doesn't know much about the population
When the researcher wants the responses to be as diverse as possible.
Given that g(4)=9 and g(-11)=k, find the value of k that would result in a slope of 5 between the two points.
Answer:
[tex]k=-66[/tex]
Step-by-step explanation:
So we are given two values:
[tex]g(4)=9 \text{ and } g(-11)=k[/tex]
They can be interpreted as: (4,9) and (-11,k).
So, we want to find the value of k such that the slope of the line between the two points would be 5.
Recall the slope formula. It is:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Let (4,9) be x₁ and y₁ and let (-11,k) be x₂ and y₂. Substitute 5 for m. Therefore:
[tex]5=\frac{k-9}{-11-4}[/tex]
Simplify the denominator:
[tex]5=\frac{k-9}{-15}[/tex]
Multiply both sides by -15. The right side cancels:
[tex]-15(5)=(-15)\frac{k-9}{-15}\\ -75=k-9[/tex]
Now, add 9 to both sides. The right side cancels.
[tex](-75)+9=(k-9)+9\\k=-66[/tex]
Therefore, k is -66.

Answer:
its flipped over the y axis and then it goes 6 to the right and 6 up. To find how they are congruent, just use Pythagorean theorem to find the side lengths for each side and say that by using the rule SSS or side side side you know that the triangles are the same.
Step-by-step explanation:
to find the side length with Pythagorean theorem for example for side DE, side DE is basically the hypotenuse of the triangle to just count the height and base using the graph and in this case it would be h=6 b=3 and then use the Pythagorean theorem to find the actual side length of the line, which would be √45.
