Please help! I need the details for the transformations.
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.
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.
how do transformations preserve distance and angle?
Answer:
When a transformation doesn't change the side lengths and angle measurements
of a shape, we call this preserving length and angle measurement. These are rigid
transformations . Translations, rotations, and reflections are all rigid
transformations .
When constructing the bisector of a line segment, you are also constructing the
perpendicular bisector of a line segment. true or false Explain your reasoning.
Answer:
True
This is so because the line is drawn from points on both sides of the line to be bisected, which are equidistant from the ends and the center of the line to be bisected line giving an angle of 90° at the intersection of both lines.
Step-by-step explanation:
The steps for constructing the bisector of a line segment includes the following
1) The compass is placed at one end of the line segment
2) The width of the compass is adjusted so as to be wider than half the length of the line segment
3) Arcs are now to be drawn above and below the line segment to be bisected
4) From the other end of the line to be bisected with the same compass width, draw arcs above and below the line segment to be bisected to intersect the previous arcs drawn above
5) With a straight edge draw a line through the intersection of the arcs to draw the bisector
The line so drawn is the perpendicular bisector because it is drawn from points on both sides of the bisected line equidistant from the ends and the center of the bisected line.

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.
If y varies inversely as x, and y = 14 when x = 8, find y when x = 7.
Answer:
y = 16
Step-by-step explanation:
Given y varies inversely as x then the equation relating them is
y = [tex]\frac{k}{x}[/tex]
To find k use the condition y = 14 when x = 8, thus
14 = [tex]\frac{k}{8}[/tex] ( multiply both sides by 8 )
112 = k
y = [tex]\frac{112}{x}[/tex] ← equation of variation
When x = 7, then
y = [tex]\frac{112}{7}[/tex] = 16

A chocolate shop sold 1 1/4 ounces of white chocolate. It sold 8 1/4 times as much milk chocolate as white chocolate. How many ounces of milk chocolate did the shop sell?
Answer:
10.3125 (NOT ROUNDED)
Step-by-step explanation:
1. I changed it to decimals. 1/4 can easily be changed into a decimal.
2. I set 1/4 = x/100. Then cross multiplied. That would give you 4x = 100.
3. Now you would simplify that. x would be 25. So its 25/100 wich then turns to .25.
4. Now you are going to replace them so it would be 1.25 and 8.25.
5. To find out how much milk chocolate there was you would multiply 1.25 and 8.25.
6. That's your final answer
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

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

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
Find the area the sector.
Answer:
34π/3 (= 11.3 π ) mi²
Step-by-step explanation:
(see attached for reference)
area of sector is given by:
A = (θ/360) π r²
where
θ = angle of sector (given as 255°)
r = radius (given as 4 miles)
substituting the known values into the formula:
A = (θ/360) π r²
A = (255/360) π (4)²
A = (255/360) π (16)
A = 34π/3 mi²
A = 11.3 π mi²

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 .

6:10 is the ratio
Step-by-step explanation:

Help!!!!!!!!!!!!!!!!!!!!
======================================================
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.
