Olin [163]

Answer:

If the base of the prism has dimensions x and y, and the diagonal along the base is represented by c, then x² + y² = c². The longest diagonal in the solid, s, is the hypotenuse of the triangle formed by the sides c and the height of the solid, z. So we know that, c² + z² = s².

Suppose Brandi buys a CD for $1000 that earns 3% APR and is compounded
Dovator [93]

Answer:

$1,061.76

Step-by-step explanation:

(refer to attached handout)

For compound interest, you are given:

A = ? (need to find)

P = $1000

r = 3% = 0.03

n = compounded monthly = 12 times per year

t = 2 years

(substituting this into the formula)

A = P [  1 + (r/n) ] ^(nt)

A = 1000 [  1 + (0.03/12) ] ^[(12)(2)]

A = 1000 [  1 + 0.0025 ] ^24

A = 1000 [  1.0025 ] ^24

A = 1,061.76

the admission fee at an amusement park is $3.50 for children and $7.20 for adults. on a certain day, 344 people entered the park
snow_lady [41]

Answer:

180 adults, 164 children

Step-by-step explanation:

Assuming all the people admitted are children,

total fees collected

= 344($3.50)

= $1204

Difference in amount collected

= $1870 -$1204

= $666

This difference in amount is due to the extra cost from each adult admission fee that we assumed to be children.

Difference in each admission fee

= $7.20 -$3.50

= $3.70

Number of adults admitted

= $666 ÷$3.70

= 180

Number of children admitted

= 344 -180

= 164
