deff fn [24]3 years ago
7 0

Answer:

b=10

Step-by-step explanation:

Evaluate exponents: 36-4b+4=0

Combine like terms: 40-4b=0

Add 4b to both sides: 40=4b

Divide both sides by 4: 10=b

So b=10

OverLord2011 [107]
Answer: The surface area of the triangular prism is 448 square millimeters.

To find the surface area, we just need to input our values into the formula that is given.

SA = 2B + Ph
SA = 2(84) + 56(5)
SA = 168 + 280
SA = 448

The final surface area is 448 mm^2.

Belinda bought a car one year ago.
lesya692 [45]

Answer:

$16,500

Step-by-step explanation:

The computation of the amount that should be paid for the car is shown below:

Since the car would be purchased one year ago

And, the value of the car would be decreased by 15% to $14025

So the amount that should be paid is

= $14025 × 100 ÷ (100 - 0.15)

= $16,500

Rasheed bought two kinds of candy bars, chocolate and toffee, that came in packages of 2 bars each. He handed out 2/3 of the cho
Contact [7]

Answer:

9 packages of chocolate bars

Step-by-step explanation:

Let he bought c packages of chocolate bars and t packages of toffee bars,

Since, he bought 1 fewer package of chocolate bars than toffee bars.

⇒ c = t - 1  -----(1)

Also, he handed out out \frac{2}{3} of the chocolate bars and \frac{3}{5} of the toffee bars,

If he handed out the same number of each kind of candy bar.

\implies \frac{2}{3}\times c=\frac{3}{5}\times t

10c = 9t     ( By cross multiplication )

\implies t=\frac{10}{9}c    ( Division property of equality )

From equation (1),

c=\frac{10}{9}c-1

1=\frac{10}{9}c-c

1=\frac{10c-9c}{9}

1=\frac{c}{9}

\implies c = 9

Hence, he bought 9 packages of chocolate bars.
