Find the surface area of the 4 walls by doing
2(8.5x3.4) + 2(6.5x3.4)
Then subtract the area of the 2 doors , which is 4
So the total painted surface will come out to be 98m
Multiply 98 by the cost, £160 to get a total cost of £15680 to paint the room

10 to the power of 3 times what equals 630
vekshin1
10³ · x = 630
x = ?

10³ = 10 × 10 × 10 = 1,000

630 ÷ 1000 = x
630 ÷ 1000 = 0.63
x = 0.63

So we have:

10³ · 0.63 = 630

Bobby put 1/3 of his lawn mowing money into his savings and uses the remaining 2/5 to buy a video game. If he has $12 left, how
Alexeev081 [22]

Given:

Bobby put 1/3 of his lawn mowing money into his savings

He uses the remaining 2/5 to buy a video game.

He has $12 left.

To find:

The amount did he have at first.

Solution:

Let x be the initial amount.

Bobby put 1/3 of his lawn mowing money into his savings. So, the remaining amount is

x-\dfrac{1}{3}x=\dfrac{2}{3}x

He uses the remaining 2/5 to buy a video game. Then the remaining amount is

Remaining=\dfrac{2}{3}x-\dfrac{2}{3}x\times \dfrac{2}{5}

Remaining=\dfrac{2}{3}x-\dfrac{4}{15}x

Remaining=\dfrac{10x-4x}{15}

Remaining=\dfrac{6x}{15}

Remaining=\dfrac{2x}{5}

It is given that the remaining amount is $12.

12=\dfrac{2x}{5}

12\times 5=2x

60=2x

Divide both sides by 2.

\dfrac{60}{2}=x

30=x

Therefore, Bobby have $30 at first.

How do we solve this problem?
MaRussiya [10]
To solve the problem you must find the area of every square. For F one of the squares has a side length of 3 and because this is a square the other sides are also 3. To find the area we multiply two of the sides so 3 times 3 is 9
You do this with both the other squares
3*3=9
4*4=16
The area of the large square is given as 25
So 9+16=25 which means this is not the correct answer

H.
9*9=81
Given as 144
The area of the large square is 21*21 which is 441
144+81= 225
So because the two small squares DO NOT equal the area of the large square this is the correct answer.

WILL MARK BRAINIEST IF CORRECT.
bonufazy [111]

Answer:

1, 2, 5 and 6 are the answers.

Step-by-step explanation:

2 is correct because the arrow shows that the number line continues till infinity. 5 is correct because any fraction is possible as no restriction of integer value is placed. Any number less than 7 is not included. There are some confusions with 1 as it's not a solid color, So, I assume -7 is not included.
