Elijah builds model airplanes at a constant rate. He can build 5 model airplanes in 150 minutes, and 10 model airplanes in 300 minutes. How long would it take him to build 15 model airplanes.

Answers

Answer 1

Answer:

450 minutes

Step-by-step explanation:

Since Elijah can build 5 model airplanes in 150 minutes. He can build 1 model airplane in 30 minutes. To find this you divide 150 by 5. The question asks for how many minutes it would take Elijah to build 15 model airplanes. Since 1 x 15 = 15 model airplanes, you use proportions and also multiple the time by 15, so 30 x 15 = 450 minutes.

Answer 2

Answer:

450 Minutes or 7 hours 30 minutes

Step-by-step explanation:

Because the rate of Sets to minutes is 1:30 for every 1 he builds it take 30 minutes so 30 x 15 = 450 or 150 x 3 because every 5 sets there 150 minutes

Hope this helped :)

If A is a square matrix of order 2, then det(-3A) is *
a. 3 det A
b. -3 det A
c. 9 det A
d. -9 det A
Help please.​

Answers

Answer:

c. 9 det A

Step-by-step explanation:

Given the following data;

Since A is a square matrix of order 2, we know that n = 2

K = 3

For any scalar k;

∣kA∣ = k^{n} ∣A∣

Substituting into the equation;

∣-3A∣ = -3²∣A∣

Simplifying, we have;

∣-3A∣ = 9∣A∣

= 9 detA

Therefore, det (-3A) = 9 detA

3 folders cost $2.91 dollar sign . Which equation would help determine the cost of 2 folders? WRITE THE LETTER IN THE SPACE BELOW.

Answers

Answer:

$1.94

Step-by-step explanation:

Cost of 3 folders = $2.91

We need to find the cost of 2 folders.

First we will find the cost of 1 folder

1 folder = $2.91/3 = $0.97

To find the cost of 2 folders, multiply $0.97 and 2

2 folders = $0.97 × 2

= $1.94

Hence, the cost of 2 olders is $1.94.

El porcentaje de depreciación de la auto de Mira por año es del 12,79 %.

Cómo calcular el valor de depreciación del auto de Mira por año?

Para calcular el valor de depreciación del auto de Mira debemos tener en cuenta la siguiente información:

Precio del auto nuevo: $18,645Precio residual de auto: $1,950Vida útil de auto: 7 años.

De acuerdo a la información anterior, debemos calcular cual es la diferencia entre el precio nuevo y el precio residual.

$18,645 - $1,950 = $16,695

Ahora, para saber el valor de depreciación por año dividimos este valor ($16,695) en 7.

$16,695 ÷ 7 = $2,385

Por ultimo para saber el porcentaje de depreciación por año realizamos el siguiente procedimiento:

$18,645 ÷ 100 = $186.46$2,385 ÷ $186.46 = 12,79%

So option 4 is correct.

Let the number that makes equation true is x

The question is that what makes equation true

This equation is a linear expression with one variable and rational numbers.

This equation can be solved in the following way

[tex]\rm -5 +x = -\dfrac{22}{3} \\x = 5 -\dfrac{22}{3} \\x = (15-22)/3 \\x = -7/3\\ x= -2\dfrac{1}{3}[/tex]

Answers

Step-by-step explanation:

1st day: 6 seashells, 14.7 dollars

2nd day: 3 seashells, 7.35 dollars

3rd day: 7 seashells, 17.15 dollars

All together: 39.2 dollars

day 3 = 7

day 2 = 7 - 4 = 3

day 1 = 3 * 2 = 6

total seas shells = 7 + 3 + 6 = 16

total money = 16 * 2.45 = $39.20

Richard invests $230.92 every month into his mortgage. At the end of 30 years, he has a balance of $184,033.06. What interest did he make over 30 years?

Answers

The answer is $101,233.06

Richard made $100,719.46 in interest over 30 years on his mortgage.

To calculate the total interest Richard made over 30 years, we need to find the total amount he invested and then subtract that from the final balance.

Richard invests $230.92 every month for 30 years, which is a total of:

Total investment = 30 years * 12 months/year * $230.92/month

Total investment = $230.92 * 360

Total investment = $83,313.60

Now, we can calculate the interest earned by subtracting the total investment from the final balance:

Interest = Final balance - Total investment

Interest = $184,033.06 - $83,313.60

Interest = $100,719.46

Therefore, Richard made $100,719.46 in interest over 30 years on his mortgage.
