Answer:

x = $\sqrt{1}$

Step-by-step explanation:

(x + 6 )^2 = 49

get rid of the square , by square rooting the 49

x + 6 = $\sqrt{49}$

x = $\sqrt{49}$ -6

x = $\sqrt{1}$

$\sqrt{49}$ means + or - hence it could be -7 -6 = -1 ... or 7-6 = 1

therefore the answer is = or - 1

hence in terms of roots .. answer is :

$\sqrt{1}$

What is the area of the trapezoid?

kykrilka [37]

To find the area of the trapezoid you add the two bases then multiply by the base and divide by 2.

B1+b2= 24+16=40
40*h=40*12=480
480/2=240

D. 240 square feet.

The senior class want to play a practical joke on the principal, who was a former college basketball star. They want to fill his

steposvetlana [31]

The number of basketball that will fill up the entire office is approximately 16,615.

Recall:

Volume of a spherical shape = $\frac{4}{3} \pi r^3$

Volume of a rectangular prism = $l \times w \times h$

Given:

Diameter of basketball = 9.5 in.

Radius of the ball = 1/2 of 9.5 = 4.75 in.

Radius of the ball in ft = 0.4 ft (12 inches = 1 ft)

Dimension of the office (rectangular prism) = 20 ft by 18 ft by 12 ft

First, find the volume of the basketball:

Volume of ball = $\frac{4}{3} \pi r^3 = \frac{4}{3} \times \pi \times 4.75^3\\$

Volume of basketball = $448.92 $ in^3$

Convert to $ft^3$

$1728 $ in.^3 = 1 $ ft^3$

Therefore,

Volume of basketball = $\frac{448.92}{1728} = 0.26 $ ft^3$

Find the volume of the office (rectangular prism):

Volume of the office = $20 \times 18 \times 12 = 4,320 $ ft^3$

Number of basket ball that will fill the office = Volume of office / volume of basketball

Thus:

Number of basket ball that will fill the office = $\frac{4,320}{0.26} = 16,615$

Therefore, it will take approximately 16,615 balls to fill up the entire office.

Answer:

1.92 miles

Step-by-step explanation:

she had walked 10 miles so that is where you start

Monday she had walked 2.38 so you subtract that from her total

Tuesday she had walked 2.4 so you subtract that from your new total

Wednesday she had walked 3.3 and you subtract that from the new total also

Thursday she had not walked anything so your remaining total is the amount she had walked on Friday
