Answer: 136 square feet
=======================================================
Explanation:
The front face is a triangle with base 6 and height 4.
The area is 0.5*base*height = 0.5*6*4 = 12 square feet
The back face is also 12 square feet since the front and back faces are identical triangles.
So far we have 12+12 = 24 square feet of surface area.
--------------------
The bottom face, that runs along the floor or ground, is a rectangle that is 6 ft by 7 ft. So we have 6*7 = 42 square feet of surface area here. This adds onto the 24 we found earlier to get 24+42 = 66 square feet so far.
To find the left and right upper faces, we'll need to find the length of the hypotenuse first. The 6 ft cuts in half to 3 ft. The right triangle on the left has side lengths of 4 ft and 3 ft as the two legs. Use the pythagorean theorem to find the hypotenuse is 5 ft. We have a 3-4-5 right triangle.
This means the upper left face is 5 ft by 7 ft leading to an area of 5*7 = 35 square feet. The same can be said about the upper right face.
So we add on 35+35 = 70 more square feet to the 66 we found earlier to get a grand total of 70+66 = 136 square feet of surface area.
M is a directly proportional to r cubed when r=4 M=160
1) work out the value of M when r=2
2) work out the value of r when M=540
Answer:
1) When r = 2, M = 20.
2) When M = 540, r = 6.
Step-by-step explanation:
M is a directly proportional to r cubed
This means that the equation for M has the following format:
[tex]M = ar^3[/tex]
In which a is a multiplier.
When r=4 M=160.
We use this to find a. So
[tex]M = ar^3[/tex]
[tex]160 = a(4^3)[/tex]
[tex]64a = 160[/tex]
[tex]a = \frac{160}{64}[/tex]
[tex]a = 2.5[/tex]
So
[tex]M = 2.5r^3[/tex]
1) work out the value of M when r=2
[tex]M = 2.5*2^3 = 2.5*8 = 20[/tex]
When r = 2, M = 20.
2) work out the value of r when M=540
[tex]M = 2.5r^3[/tex]
[tex]540 = 2.5r^3[/tex]
[tex]r^3 = \frac{540}{2.5}[/tex]
[tex]r^3 = 216[/tex]
[tex]r = \sqrt[3]{216}[/tex]
[tex]r = 6[/tex]
When M = 540, r = 6.

Ms. Neil has 25% of her class who have turned in their reading logs. 7 students have
turned in their logs. Enter the total number of students in her class.
Answer:28
Step-by-step explanation:
25% × x = 7
Multiplying both sides by 100 and dividing both sides by 25,
we have x=7 x 100/25
7×100÷25
x=28

9. Translate the sentence into an equation and solve. Use x as the variable.
The difference between six times a number and four is equal to fifty.
A. 6(x-4) = 50; x = 9
B. 6x - 4 = 50; x = 9
C. 6 +X-4 = 50; x = 12
D. 6x-4 = 50; x = -9
Answer:
Option B: 6x-4=50; x=9 is the correct answer.
Step-by-step explanation:
Given that:
x is the variable used for number.
6 times a number means 6x and difference means subtraction.
Thus according to given statement;
6x - 4 = 50
Adding 4 on both sides
6x - 4 + 4 = 50+4
6x = 54
Dividing both sides by 6
[tex]\frac{6x}{6}=\frac{54}{6}\\x=9[/tex]
Hence,
Option B: 6x-4=50; x=9 is the correct answer.

PLEASE HELP 8 ml of a 80% acid solution was mixed with 12 ml of a 20% acid solution. What is the percentage of acid in the new solution?
Answer:
44%
Step-by-step explanation:
So you have 2 bottles. One bottle is 8ml and is 80% acid. the other is 12 ml and is 20% acid.
This means there's 6.4 ml of acid in bottle 1(8*0.8) and 2.4 ml of acid in the other one(12*0.2).
The total amount of liquid is 8+12 = 20
The total amount of acid is 6.4+2.4 = 8.8
Percentage of acid in the new solution is 8.8/20 = 0.44 = 44%

Answer:
AC ; AB ; BC
Step-by-step explanation:
Recall that largest angles will oppose largest sides in a triangle, therefore, the angles in order of greatest to smallest are:
<B (84); <C (60); <A (36)
Their opposite sides will keep the same order from largest to smallest:
AC ; AB ; BC
The side lengths, in order from greatest to least, are
