Answer:
[tex]x=\frac{3}{4}=0.75[/tex]
Step-by-step explanation:
From the shape of the quadrilateral, we can assume that it is a parallelogram. In a parallelogram, opposite sides are congruent and thus have the same length.
In this case, we are given that two opposite sides have lengths of [tex]4x+5[/tex] and [tex]8[/tex]. Therefore, since the quantities must be equal, we can write the following equation to solve for [tex]x[/tex]: [tex]4x+5=8[/tex]. Solving for [tex]x[/tex], we get:
[tex]4x+5=8[/tex]
[tex]4x=3[/tex] (Use the Subtraction Property of Equality to subtract [tex]5[/tex] from both sides of the equation, which isolates [tex]x[/tex])
[tex]x=\frac{3}{4} =0.75[/tex] (Use the Division Property of Equality to divide both sides of the equation by [tex]4[/tex] to get rid of [tex]x[/tex]'s coefficient)
Hope this helps!

A rectangular prism is 114 inch tall, 112 inch wide, and 2 inches long. How many unit cubes with side length of 14 inch does it take to fill the rectangular prism?
Answer: 9
Step-by-step explanation:
Given
The dimension of a rectangular prism is
[tex]L=2\ in[/tex]
[tex]W=112\ in.[/tex]
[tex]h=114\ in.[/tex]
Volume of Prism [tex]V=L\times W\times h[/tex]
[tex]\Rightarrow V=2\times 112\times 114=25,536\ in.^3[/tex]
The volume of the unit cube
[tex]\Rightarrow V_c=14\times 14\times 14=2744\ in.^3[/tex]
Suppose there are n unit cubes to fit in a rectangular prism
[tex]\Rightarrow n=\dfrac{V}{V_c}=\dfrac{25,536}{2744}=9.306\approx 9[/tex]

HELP HELP HELP PLZZZ right answers only and no links
Answer:
Step-by-step explanation:
Part A
x-intercepts of the graph represent the value of goods at which profit of of the company is zero → Break even of the company
Maximum value of the graph represents the maximum profit of the company at certain price of the goods.
Part B
Interval in which the function is increasing → x = 0 to x = $3
Profit of the company increases when price of the goods increase from 0 to 3.
Interval in which the function is decreasing → x = $3 to x = $6
Profit of the company decreases when the price of the goods increases from 3 to 6.
Part C
Average rate of change of the function from x = a and x = b,
= [tex]\frac{f(b)-f(a)}{b-a}[/tex]
By applying the same rule,
Average rate of change of the function between x = 1 and x = 3
= [tex]\frac{120-60}{3-1}[/tex]
= [tex]\frac{60}{2}[/tex]
= 30
a woodworker makes wooden checkerboards. identify any zeros of the function, and interpret what the zeros mean in terms of the situation
I have attached an image showing the graph of the function.
Answer:
Zeros are x = $15 and x = $70 and they are the prices at which the woodworker will neither loss nor gain money.
Step-by-step explanation:
First of all, the zeros of a function f(x) are defined as the values of x where f(x) = 0. That is the points where the graph curve touches the x-axis.
Now, from the attached graph, when we locate the point that the curve touches the x-axis, it's at x = 15 and at x = 70.
This means that f(x) = 0 at x = 15 and at x = 70.
Now, from the graph; f(x) is the profit function. So when f(x) = 0, it means there is zero profit which implies no gain and no loss.
Thus, we can conclude that the prices at which the woodworker will neither loss nor gain money is when the price is; x = $15 and x = $70

How do I find the answer to number 8?
Answer:
IT IS B ANSWER
Can someone help me with this question please
Answer:
Step-by-step explanation:
y+ 20= x+ 15( Vertically opposite angles)
y+ 20- 15= x
x= y+ 5 __(1)
3x+ 5=4y- 15
Substituting (1)
3(y+5)+ 5= 4y-15
3y+15+5=4y- 15
y=15+20
y= 35
x= 40

The wages w (in £) June earns is the number of hours she works n multiplied by her hourly rate r (in £ per hour). Enter a formula for June's wages and enter the wage she would earn if she worked 17 hours at a rate of £7.30 per hour
Answer:
Wages she earn = £124.1
Step-by-step explanation:
Given:
Number of hour work in June = 17 hour
Rate = £7.30 per hour
Find:
Wages she earn
Computation:
Wages she earn = Number of hour work in June x Rate
Wages she earn = 17 x £7.30
Wages she earn = £124.1
plz help me on this one its really hard :(
Answer:
It will be 63.9
Step-by-step explanation:
Trust me, I got it right
Answer:
63.6mm² (the last option)
Explanation:
the formula for calculating the area of a circle is πr², where r is the length of the radius.
in this case, we know that 9mm is the length of the diameter of the circle, so we can divide that by 2 to get 4.5mm for the length of the radius.
the question has instructed us to use 3.14 for π (pi), so we can substitute these values into the formula:
πr² = 3.14 × 4.5² = 63.585mm²
we can now round this to the nearest tenth to get 63.6mm², which would be the last option.
i hope this helps! :D

Answer:
Slope is -3
Equation is y = -3x + 2
Step-by-step explanation:
(0 , 2) and ( -1 , 5)
m= (y2-y1)/(x2-x1)
m= (5 - 2)/(-1 -0)
m= 3/-1
m= -3
y - y1 = m(x - x1)
y - 2 = -3(x - 0)
y - 2 = -3x + 0
y = -3x + 2

Find the length of the missing side x ... please help me
Answer:
x = 10
Step-by-step explanation:
Use Pythagorean Theorem
c2 = a2 + b2
Here you must find the hypotenuse length (x) which is c in the equation. Thus substitute the values given into the equation:
c2 = 6^2 + 8^2
c2 = 100
Square root both sides so
c = 10
Thus length of x is 10
Polygon B is a scaled copy of Polygon A using a scale factor of 5.

A family eats at a restaurant. The bill was $54. The family leaves a tip and spends $60 total. How much was the tip as a perentage of the bill? (round to the nearest whole percent)
Answer:
11%
Step-by-step explanation:
60 - 54 = $6 The tip is $6 since they were meant to pay $54 but gave $6 extra.
The bill is $54.
6/54 = 0.1 recurring
0.1 × 100 = 11.1%
11% is the percentage.
I hope that helps!! ^-^
Help? cant seem to figure this out. Appreciate it!
Answer:
327 cm²
Step-by-step explanation:
The opposite faces of a cuboid are congruent , front and back, top and bottom, the two side faces, then
SA = 2(9.5 × 8) + 2(5 × 8) + 2(9.5 × 5)
= (2 ×76) + (2 × 40) + (2 × 47.5)
= 152 + 80 + 95
= 327 cm²
Answer:
Step-by-step explanation:
SA = 2B + LA B = area of base LA = lateral area
B = area of the rectangle with length of 9.5 and width of 5
= 9.5(5) = 47.5
LA = perimeter of base times the height
= [2(9.5) + 2(5)] (8)
= (19 + 10)(8)
= 29(8)
= 232
SA = SA = 2B + LA = 2(47.5) + 232
= 95 + 232
= 327 sq cm

The chart below shows the number of sit-ups Annie did starting May 1. If this trend continues, how many sit-ups is Annie expected to do on May 11
Answer:
550 sit-ups
Step-by-step explanation:
Given
See attachment for chart
Required
Number of sit-ups on March 11
Represent the number of sit-ups with x and the days with y.
So:
[tex](x_1, y_1) = (1,50)[/tex] --- May 1
[tex](x_2, y_2) = (2,100)[/tex] --- May 2
First, we calculate the slope of the line chart.
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{100 - 50}{2-1}[/tex]
[tex]m = \frac{50}{1}[/tex]
[tex]m = 50[/tex]
Next, we calculate the equation using:
[tex]y = m(x - x_1) + y_1[/tex]
This gives:
[tex]y = 50(x - 1) + 50[/tex]
[tex]y = 50x - 50 + 50[/tex]
[tex]y = 50x[/tex]
So, on May 11.
[tex]x= 11[/tex]
Substitute 11 for x
[tex]y = 50 * 11[/tex]
[tex]y = 550[/tex]
