Find the total surface area

Answers

Answer:

47

Step-by-step explanation:

9+9+9+9+7+7

forgive me if i am wrong

Answer:

147 cm^2

Step-by-step explanation:

To find the surface area, you would have to add up the area of all shapes:

Area of triangle: 1/2 base*height

Area of square: length*width

----------

square = l*w = 7*7 = 49 cm^2

----------

So since there are 4 triangles, you would have to multiply the result by 4.

triangle = 1/2 7*9 = 49/2 = 24.5

4 triangles = area of 1 triangle * 4 = 4(24.5) = 98 cm^2

----------

add them up, and you get 49 + 98 = 147 cm^2

How many gallons of a 20% antifreeze solution and a 15% antifreeze solution must be mixed to obtain 30 gal of a 18% antifreeze solution? Round to the nearest gallon

Answers

Answer:

20% antifreeze solution = 18 gal

15% antifreeze solution = 12 gal

Step-by-step explanation:

Let

20% antifreeze solution = x

15% antifreeze solution = y

x + y = 30

0.20x + 0.15y = 30 * 0.18

0.20x + 0.15y = 5.4

x + y = 30 (1)

0.20x + 0.15y = 5.4 (2)

From (1)

x = 30 - y

Substitute x = 30 - y into (2)

0.20x + 0.15y = 5.4 (2)

0.20(30 - y) + 0.15y = 5.4

6 - 0.20y + 0.15y = 5.4

- 0.20y + 0.15y = 5.4 - 6

-0.05y = -0.6

y = -0.6/-0.05

y = 12 gal

Substitute y = 12 into (1)

x + y = 30 (1)

x + 12 = 30

x = 30 - 12

x = 18 gal

20% antifreeze solution = 18 gal

15% antifreeze solution = 12 gal

Justin is evaluating the expression 12.5 + 3.8 x, when x is 7.9. 12.5 + 3.8 (7.9). 16.3 (7.9). 128.77. What was Justin's error? Justin should have multiplied 12.5 and 7.9 first. Justin should have added 12.5 and 7.9 first. Justin should have multiplied 3.8 and 7.9 first. Justin should have added 3.8 and 7.9 first.

Answers

Answer: Justin should have multiplied 3.8 and 7.9 first.

Step-by-step explanation:

Given the equation

12.5 + 3.8x

where, x = 7.9, the first thing that Justin's should have done was to multiply 3.8 and 7.9 first. This will be:

= 12.5 + 3.8x.

= 12.5 + 3.8(7.9)

= 12.5 + 30.02

= 42.52

Answer: (C) Answer: Justin should have multiplied 3.8 and 7.9 first.

Use the table definitions of H(t) and r(t) shown below to find (H o r)(3.0)

Answers

Answer:

C

Step-by-step explanation:

Given the tables of H(t) an r(t), we want to find:

[tex](H\circ r)(3.0)[/tex]

As stated, this is equivalent to:

[tex]=H(r(3.0))[/tex]

Using the r(t) table, we can determine that:

[tex]r(3.0)=2.0[/tex]

Therefore:

[tex]H(r(3.0))=H(2.0)[/tex]

And by using the H(t) table, we can determine that:

[tex]H(2.0)=2.5[/tex]

So, our answer is C.
