Answer:95.12

Step-by-step explanation:trust me

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

Answer:

the ratio is 12:8 boys to girls

Step-by-step explanation:

if the amount of boys is 12 then multiply the 3 by 4 and using distribution multiply the 2 by 4 as well to get 8 girls

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.

Answer:

answer is -8.4 if you add 3.6 and two it's 5.6 times 1.5 it will be -8.4

Answer:

2.4

Step-by-step explanation:

It should be 2.4 based on what I see here.  Distribute -1.5 into -3.6 + 2 to get 5.4 - 3.  You should get 2.4 as your answer in which it is the second option, the picture needs to be in standing position next time because it is upside down though but it can be flipped either way.

Step-by-step explanation:

If the exchange rate is 1 Euro to 0.80 pounds

So,

30 Euro=0.8×30=24.0=24 pounds.

so,

24 pounds would you spend to purchase something that costs 30 Euros

Answer: let's try the Second one ( sorry if i get it wrong)

Step-by-step explanation:

Each number in the sequence is called a term. In the sequence 1, 3, 5, 7, 9, …, 1 is the first term, 3 is the second term, 5 is the third term, and so on. The notation a 1, a 2, a 3,… a n is used to denote the different terms in a sequence. The expression a n is referred to as the general or nth term of the sequence.

Answer:

it is the first one

you convert  1 3/4 to improper fraction so 7/4. then divide 7/4 by 2 which is 0.875. 0.875+7/4= 2.625 which is 2 2/3.

The decimal equivalent of 1/18 is 0.125

Answer:

3.0

Step-by-step explanation:

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.

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%
