m is 12 and x is 11.25

Step-by-step explanation:

Step 1:

Find side m of the triangle. Given the sides are 3m - 4, 3m - 4 and m. Perimeter = 76 inches

⇒ m + 2(3m - 4) = 76 (Since perimeter of a triangle = sum of its sides)

⇒ m + 6m - 8 = 76

⇒ 7m = 84

⇒ m = 12 inches

Step 2:

Find x. Given side of the square is 4x + 5 and perimeter = 200

⇒ 4 × (4x + 5) = 200 (Since perimeter of a square = 4 × side)

⇒ 16x + 20 = 200

⇒ 16x = 180

⇒ x = 11.25

Answer:

Company A is 1.99 times B.

Step-by-step explanation:

Company A charges:

$A=70.50+0.50=\$71/mile$

Company B charges:

$B=35.50+0.09=\$35.59/mile$

$x=A/B=1.99$

Therefore, company A is 1.99 times B.

A man invests $2000 in an account that pays 6.5% interest per year, compounded quarterly.

skelet666 [1.2K]

Answer:

The correct answer is a. $2275.28; b. 17.04 years

Step-by-step explanation:

Principal to be invested is $2000

Interest rate (r) per year is 6.5 quarterly.

Interest is calculated compoundly.

a. Time (t) for the investment is given to be 2 years.

Amount after two years is = Principal × $( 1+ \frac{r}{100n}) ^ {nt}$ where the value of n is 4.

⇒ A = 2000 × $( 1+ \frac{6.5}{400}) ^ {8}$

⇒ A = $2275.28.

b. Now the value of A is given to be triple the principal = $ (3 × 2000).

Therefore we need to find the value of t.

⇒ 3 × 2000 = 2000 × $( 1+ \frac{6.5}{400}) ^ {4t}$

⇒ ㏑ 3 = 4t × ㏑ ( 1.01625)

⇒ t = 17.04

Therefore it would take 17.04 years for the principal to triple.

Jake is observing the population growth of insects. He started with 24 insects and the population triples every day.

Artemon [7]

Everyday the number is tripled by 3 and x represents the number of days, which we don’t know, so it would be 3x.
He started with 24.

So the equation is:

24+(3x)
