96 bricks
Step-by-step explanation:
Alan does 1/5 of the job in an hour. Gavin does 1/7 of the job in an hour
Together, 12/35 of the job should be done in an hour. In [tex]2 \frac{11}{12}[/tex] hours, the work should be done.
rate at 4 hours=[tex]2 \frac{11}{12}[/tex]*(normal speed-26)
To clarify, x=the normal rate
4 hours(normal rate-26)=[tex]2 \frac{11}{12}[/tex](normal rate)
4(x-26)=[tex]2 \frac{11}{12}[/tex]x
x=96

Answer:
B. 150 ft
Step-by-step explanation:
Perimeter of a rectangle = 2(Length) + 2(Width)
Here, we are given the perimeter and width and we want to find the length
We can do so by plugging in what we are given into the perimeter formula and solving for length.
Perimeter = 2(Length) + 2(Width)
Perimeter = 450 and Width = 75
450 = 2(Length) + 2(75)
We now solve for length
==> simplify multiplication 2(75) = 150
450 = 2(Length) + 150
==> subtract 150 from both sides
300 = 2(Length)
==> divide both sides by 2
150 = Length
And we are done!
The answer is B 150ft

What value of y makes the equation 6(x-4)+2 = 36/4 true?
Answer:
31/6
Step-by-step explanation:
36/4=9
6x-22= 9
6x= 9+22
substitute 6x=31= 31/6
Answer:
x = 31/6
Step-by-step explanation:
first lets isolate the equation which equals, 6x-24+2 = 9
I got 9 from 36/4, divide top and bottom by 4 = 9
Next add the numbers, 6x -24+24= 9 turns into 6x-22= 9
Now move the -22 to the side the 9 is, 6x= 9+22
and now we can solve and substitute, 6x=31, which gives us 31/6

Hello!
Solve:
4(3a - 4) = 563a - 4 = 14 (factoring out 4)3a = 18 (adding 4 to both sides)a = 6 (dividing by 3)Another way:
4(3a - 4) = 5612a - 16 = 56 (distributive property)12a = 72 (moving like terms)a = 6 (dividing by 12)Distributive Property of Multiplication:

the volume of a hemisphere with a diameter of 7.6 m, rounded to the nearest tenth of a cubic meter is 919.4 cubic meter.
what divided by 4 is 8?
Answer:
32
Step-by-step explanation:
If the question is x (standing for an unknown number) divided by 4 equals 8, then 8 times 4 should equal that unknown number.
x / 4 = 8
x / 4 (*4) = 8 (*4)
x = 32
We now can replace x with our number and see if this answer is valid.
x / 4 = 8
32 / 4 = 8
And yes, it is true. Therefore, 32 divided by 4 is 8.
I hope this helps! Have a lovely day!! :)

The horizontal flat box has dimensions of
h = 2
w = 7
l = 21
The vertical box has dimensions of
h = 10
w = 7
L = 12
Formula
V = L * w * h
Solution
Horizontal Flat Box = L*w * h
Horizontal Flat Box = 21 * 7 * 2
Horizontal Flat Box = 294
Vertical Box
Vertical Box = L * w * h
Vertical Box = 12*7 * 10
Vertical Box = 840

Jackson has a cube. Each edge of the cube is 5 centimeters long, as shown below.
Part A
Jackson paints every face of the cube. What is the total surface area, in square centimeters, of the cube
Jackson paints? Be sure to show your work and explain your reasoning.
Part B
After the paint dries, Jackson cuts the cube in half. He makes the cut along the diagonal of one pair of
parallel faces. Rounded to the nearest thousandth, the diagonal has a length of 7.071 centimeters. Once
the cut is made, Jackson has two identical triangular prisms.
What is the combined area, in square centimeters, of the surfaces of the two prisms that were not painted?
Part C
Jackson has a second cube identical to the first. He cuts off the triangular prism as shown below and throws
it away.
What is the volume, in cubic centimeters, of the remaining solid? Show or explain all your work.
Answer:
Part A- Surface area = 150cm squared
Step-by-step explanation:
First you find the area of one side of the cube-
side length (5) x side length (5) = area (25)
25 is the area of one side of the cube.
Then you multiple the area of one side (25) by the amount of sides that there are (6)-
25 x 6 = 150

Find the missing angle measure.
Will give brainliest if possible!!
Answer: 35°
Step-by-step explanation:
Step #1: Write the 'triangle sum theorem' for the triangle which is:m∠A + m∠B + m∠C = 180°
Step #2: Substitute the given angle measures40° + 105° + m∠C = 180°
Step #3: Simplify.m∠C + 145° = 180°
Subtract 145° from both sides.
m∠C = 35°
So, the measure of the missing angle (x) is 35°.
