Find d and all three sides

Answers

Answer 1

Answer: The triangles are congruent so $2d+10$ and $45-3d$ are the same

So we have
$2d+10=45-3d$
⇒ $5d+10=45$
⇒ $5d=35$
⇒ $d=7$

Plug in:
$2d+10=2(7)+10=14+10=24$
$45-3d=45-3(7)=45-21=24$
$d+8=7+8=15$

Darnell’s house was valued at $134,670 and it appreciated 3 percent per year. What is its value after 2 year? Round to the nearest dollar. A: $8,201 B:$142,871 C:$126,939 D:$277,541

Answers

Answer:

Option B is correct.

Step-by-step explanation:

Given: Value of House, P = $ 134,670

Rate of depreciation, R = 3% per year

Time, T = 2 years ⇒ n = 2

To find: value of house after 2 year that is A.

We know that

$A=P(1-(R)/(100))^n$

$A=134670(1+(3)/(100))^2$

$A=134670*1.0609$

A = 142871.403

A = $ 142871

Therefore, Option B is correct.

134,670×(1+0.03)^(2)=142,871

hn and 4 friends are going out for pizza for lunch. They split one pizza and 5 large drinks. The pizza cost $10.00. After using a $4.00 gift certificate, they spend a total of $13.50. Write an equation to model this situation, and find the cost of one large drink.

Answers

5d + 10 - 4 = 13.50 <== ur equation
5d + 6 = 13.50
5d = 13.50 - 6
5d = 7.5
d = 7.5/5
d = 1.50 <== what each drink costs

Monica’s school band held a car wash to raise money for a trip to a parade in New York City. After washing 125 cars, they made $775 from a combination of $5.00 quick washes and $8.00 premium washes. Let x represent the number of quick washes and let y represent the number of premium washes. Which system of linear equations represents the situation? 5x + 8y = 775 and x + y =125 5x – 8y = 125 and x + y = 775 5x + 8y = 775 and x – y = 125 5x – 8y = 125 and x – y = 775
