Tanya paints the walls of her family room.

Mathematics
1 answer:
galina1969 [7]2 years ago
8 0

Answer:

6.1

Step-by-step explanation:

Surface area of the room = 2(lw + hl + hw)

Where,

l = length = 7 m

w = width = 4 m

h = height = 3 m

Surface area of the room = 2(lw + hl + hw)

= 2(7*4 + 3*7 + 3*4)

= 2(28 + 21 + 12)

= 2(61)

= 122 m²

A 4-L can of paint covers 40 m²

Number of 4-L can of paint needed for 1 coat = 122 m² / 40 m²

= 3.05 4-L can of paint

The walls need 2 coats of paint

Number of 4-L can of paint needed for 2 coats = Number of 4-L can of paint needed for 1 coat × 2

= 3.05 × 2

= 6.1 4-L can of paint

0.75*0.8= \frac{75}{100} * \frac{8}{10} = \frac{75*8}{100*10} = \frac{600}{1000} = \frac{6}{10}=0.6

What is a1? what is d? what’s the equation? what is a7? what is a59?
Zina [86]
Answer:

a1 = 2

d = 3

an = 2 + (n - 1) * 3

a7 = 20

a59 = 176

Steps:

a1 is the initial value (when n equals 1), and since there are 2 crosses, it is 2.

d is the added value to each amount of crosses. And since the second amount is 5 and the third amount is 8, we can determine that each n is adding 3 crosses, therefore making d = 3.

The equation is simply plugging in the values for a1 and d.

A7 is simply plugging in 7 for n in the equation and solving for it. So;

a7 = 2 + (7 - 1) * 3

a7 = 2 + 6 * 3

a7 = 2 + 18

a7 = 20

And same thing as the last for 59 except substitute 59 in for where you put 7;

a59 = 2 + (59 - 1) * 3

a59 = 2 + 58 * 3

a59 = 2 + 174

a59 = 176

7 divided by 20 is what answers
Montano1993 [528]
Hello! 

The Correct Answer to this is that <span>7 divided by 20 or 7/20 equals:

"7/20 = 0.35"

</span>Explanation:

Since you are trying to find equivalent values for 7/20, you can make two proportions and set them equal to each other. The following states that "7 out of 20 is equal to some amount out of 100."

<span><span>7/20</span>=<span>x/100</span></span>

Solve by cross multiplying:

<span>20x=700</span>

Divide both sides by 20 to isolate x:

<span>x=35</span><span> Therefore, </span><span><span>7/20</span>=<span>35/100</span></span><span>. This is the same as saying 35%, since by definition "per" means out of, and "cent" means hundred. To make it into a decimal just move the decimal place two digits to the left, such that 35.00 becomes 0.35, and 100.00 becomes 1. Then it is simply </span><span>0.35/1</span><span>, or 0.35</span>

<span>
Hope this Helps! Have A Wonderful Day! :)</span>
