Answer:

c = 37

Step-by-step explanation:

Pythagorean thm formula:

a² + b² = c²

Given:

a = 12

b = 35

Work:

a² + b² = c²

12² + 35² = c²

144 + 1225 = c²

c² = 1369

$\sqrt{c^2} =\sqrt{1369}$

c = 37

How can I solve this?

elixir [45]

Answer:

x=8/21

Step-by-step explanation:

(3/4)/(2/7) = 1/x

(3/4)x = (2/7)

x = (2/7) / (3/4)

x = (2/7) * (4/3)

x = 8/21

Joshua has math and reading homework tonight. Joshua can solve each math problem in 2.5 minutes and he can read each page in 3 m

liraira [26]

Answer:

Joshua solved 7 math problems and tread 14 pages.

Step-by-step explanation:

Let x be the number of math problems Joshua solved. The number of pages Joshua read is twice the number of math problems he solved, then 2x is the number of pages Joshua read.

Joshua can solve each math problem in 2.5 minutes, then x math problems he solves in 2.5x minutes.

Joshua can read each page in 3 minutes, then 2x pages he reads in $3\cdot 2x=6x$ minutes.

It took him 59.5 minutes to complete all of his homework, so

$2.5x+6x=59.5$

Solve this equation:

$2.5x+6x=59.5\\ \\8.5x=59.5\\ \\85x=595\\ \\x=7\\ \\2x=14$

Joshua solved 7 math problems and tread 14 pages.

Sarah invested $1000 in an account paying 5.5% interest compounded semi-annually. How long will it take for the account balance

NISA [10]

Answer: it will take 43.25 years

Step-by-step explanation:

We would apply the formula for determining compound interest which is expressed as

A = P(1+r/n)^nt

Where

A = total amount in the account at the end of t years

r represents the interest rate.

n represents the periodic interval at which it was compounded.

P represents the principal or initial amount deposited

From the information given,

P = $1000

A = $10450

r = 5.5% = 5.5/100 = 0.055

n = 2 because it was compounded 2 times in a year.

Therefore,.

10450 = 1000(1 + 0.055/2)^2 × t

10450/1000 = (1 + 0.0275)^2t

10.45 = (1.0275)^2t

Taking log of both sides, it becomes

Log 10.45 = 2t log 1.0275

1.019 = 2t × 0.01178 = 0.02356t

t = 1.019/0.02356

t = 43.25 years

a rectangular room is 14 feet by 20 feet.the ceiling is 8 feet high. find the length an width of the smaller wall.

noname [10]

Smaller wall would be( 8 x 14 )because the other wall is 8 x 20 which is the bigger wall because if the room is 14 x 20 x 8 then two walls would be 8 x 14 and the other two would be 8 x 20 hope that helps
