what is the unit price of 16 and 12.29, 32 and 19.98, and 128 and 34.99 (it would be really helpful to know thanks) show work
SpyIntel [72]

Answer:

The unit costs are $0.77, $0.62 and $0.27 respectively.

Step-by-step explanation:

The unit price is simply the cost of the items divided by the amount of the items that are included. So, just take the cost and divide it.

$12.29/16 = $0.77 per unit

$19.98/32 = $0.62 per unit

$34.99/128 = $0.27 per unit

One leg of triangle is 7 inches longer than the other leg. The hypotenuse is 8 inches longer than the shorter leg. The perimeter
mixas84 [53]

Answer:

5 ; 12 ; 13

Step-by-step explanation:

Let :

Shorter leg = x

Other leg = x + 7

Hypotenus = x + 8

Recall:

Hypotenus² = opposite² + adjacent²

(x+8)² = x² + (x+7)²

x² + 16x + 64 = x² + x² + 14x + 49

x² - 2x - 15 = 0

x² - 5x + 3x - 15 = 0

x(x - 5) +3(x - 5) = 0

(x + 3) = 0 ; x = - 3

(x - 5) = 0 ; x = 5

Side can't be negative ;

Hence,

x = shorter side = 5

Other side = x + 7 = 5 + 7 = 12

Hypotenus = x + 8 = 5 + 8 = 13

Leo, Kush and Mai share some money in the ratio 3:5:8
Marta_Voda [28]

Answer:

The total amount of money that they shared is \£6,000

Step-by-step explanation:

Let

x-----> amount of money Leo shares

y-----> amount of money Kush shares

z-----> amount of money Mai shares

we know that

\frac{x}{y} =\frac{3}{5}

x=\frac{3}{5}y -----> equation A

\frac{y}{z} =\frac{5}{8}

z=\frac{8}{5}y -----> equation B

\frac{x}{z} =\frac{3}{8}

z=\frac{8}{3}x -----> equation C

y=x+750 ------> equation D

substitute equation A in equation D and solve for y

y=\frac{3}{5}y+750

y-\frac{3}{5}y=750

\frac{2}{5}y=750

y=750*5/2=\£1,875

Find the value of x (equation A)

x=\frac{3}{5}(1,875)=\£1,125

Find the value of z (equation C)

z=\frac{8}{3}(1,125)=\£3,000

therefore

The total amount of money is equal to

x+y+z=\£1,125+\£1,875+\£3,000=\£6,000
