It is given that , length is 3 feet and width is 2 feet.

And we have to convert the area in square inches.

$1 feet =12 inches| therefore\\2feet = 2*12 inches = 24 inches\\3feet = 3*12 inches = 36 inches$

Area equals to the product of length and width, that is

$Area = 24*36 in^2 = 864 inches^2$

Therefore the required area in square inches is 864 square inches .

Andrea is buying some new shirts and sweaters. she is able to buy 3 shirts and 7 sweaters for $137 or she is able to buy 8 shirt

Vikki [24]

Answer:

$33

Step-by-step explanation: ( pls brainiest)

Let the cost of each shirt is $ x, and the cost of each sweater is $ y.

Since, cost of each shirt is $ x, the cost of 3 shirts will be $ 3x and cost of 2 shorts will be $ 2x.

Likewise, cost of each sweater is $ y, so the cost of 2 sweaters will be $ 2y and cost of 4 sweaters will be $ 4y.

Andrea was able to buy 3 shirts and 2 sweaters for $114. This means:

Cost of 3 shirts + Cost of 2 sweaters = 114

3x + 2y = 114 Equation 1

She was able to buy 2 shirts and 4 sweaters for $164. This means

2x + 4y = 164

Dividing both sides by 2, we get:

x + 2y = 82 Equation 2

Subtracting Equation 2 from Equation 1, we get:

3x + 2y - (x + 2y) = 114 - 82

3x + 2y - x - 2y = 32

2x = 32

x = 16

Using the value of x, in Equation 2, we get:

16 + 2y = 82

2y = 66

y = 33

Since, x represents the cost of shirt, the cost of each shirt is $ 16.

y represents the cost of sweater, so the cost of each sweater is $ 33.

I need help on this

Viefleur [7K]

Answer:

See below

Step-by-step explanation:

Which is the closest to 6

$\sqrt{34}$

$\sqrt{39\\$

$\sqrt{35$

or $\sqrt{38}$

So, find the square root of each ( I suggest using a calculator)

$\sqrt{34} = 5.83\\\sqrt{39} = 6.24\\\sqrt{35} = 5.91 \\\sqrt{38} = 6.16$

Which is closest? Let's see.

6 - 5.83 = 0.17

6.24 - 6 = 0.24

6 - 5.91 = 0.09

6.16 - 6 = 0.16

Find the smallest #

0.09 is the smallest, so 5.91 is the closest. Square the #, we get $\sqrt{35}$

Hope this helps! =D
