Answer:

<u>6 percent</u> of the money was spent on keyboards.

Step-by-step explanation:

Given:

The school principal spent $2000 to buy some new computer equipment.

Of this money , $120 was used to buy some new keyboards.

Now, to find the percent of the money spent on keyboards.

Total money spent on computer equipment = $2000.

Money spent on keyboard of the total money = $120.

So, to get the percent of money spent on keyboards:

\frac{120}{2000} \times 100

=0.06\times 100

=6\%.

Therefore, 6 percent of the money was spent on keyboards.

Hi! Can someone help me please.
Sati [7]

Answer:

27 inches

Step-by-step explanation:

We are using the Pythagorean theorem

a^2 +b^2 = c^2  where c is the hypotenuse

We are given the diagonal, which is the hypotenuse and a leg

36^2 + b^2 = 45^2

Subtract 36^2 from each side

36^2 + b^2 - 36^2 = 45^2 - 36^2

b^2 = 45^2 - 36^2

     b^2 =2025-1296

          b^2 =729

Take the square root of each side

sqrt(b^2) = sqrt(729)

b =27

Lance the alien is 5 feet tall. His shadow is 8 feet long. At the same time of day, a tree's shadow is 32 feet long. What is the height of the tree?

We solve this using proportion of

Height/ Shadow

= 5/8 = x/32

Cross Multiply

8x = 5 × 32

x = 5 × 32/8

x = 20 feet

The height of the tree is 20 feet

The Jurassic Zoo charges $8 for each adult
eimsori [14]

Answer:

21 adults and 139 children

Step-by-step explanation:

x=adult (8$)

y=child (5$)

8x + 5y =863

x+y=160

-x       -x (subtract x on both sides)

y= -x + 160

plug that in for y on the other equation

8x + 5(-x + 160) =863

distribute 5 to both

8x + -5x + 800 = 863

combine both x values

3x + 800 = 863

     -800     -800 (subtract on both sides)

3x = 63

divide by 3 on both sides

x = 21 adults

now plug x in one of the equations

21 + y = 160

-21         -21

y=139 children
