ABC ~ LMN, AB = 18, BC = 12, LN = 6. What is the scale factor of ABC to LMN?

ankoles [38]

B because the square root of a squared and b squared is = c squared, therefore, meaning if you have side c and b for triangle ABC you'll do 12"2+x=18'2
which will approximately be 13.42. you put 13.42/6= 2/1

Choose the angle whose measure is greater than 90 degrees but less than 180 degrees.

Rainbow [258]

B) An obtuse angle would have a measure between 90 and 180.

Acute triangles would have <span>a measure </span>less than 90, right angles would have a measure of exactly 90, and straight angles would have a measure of exactly 180.
Hope this helps!

6.5% of $5.00 = 0.065 * $5.00 = $0.325
converting to cents by multiplying by 100
$0.325 = 32.5 cents
round to the nearest is
33 cents is your answer.

in a survey four out of seven people named blue as their favorite color. One out of three named red.If 1,092 people were include

Dominik [7]

Answer: There are 312 people who named neither blue nor red as their favorite color.

Step-by-step explanation:

Since we have given that

Total number of people who are surveyed = 7

Number of people who named blue as their favorite color = 4

According to question, one out of three named 'red'.

So, Out of seven people , number of people who named neither blue nor red as their favorite color is given by

$7-(4+1)=7-5=2$

There if there are 1092 people who were included in the survey , then we need to find the number of people who named neither blue nor red as their favorite color.

$\frac{2}{7}=\frac{x}{1092}\\\\x=\frac{2\times 1092}{7}\\\\x=312$

Hence, there are 312 people who named neither blue nor red as their favorite color.

$18, P = $200, r = ?, t = 1.5 years. Find the annual interest rate.

faust18 [17]

Question 1)

Given

Interest I = $18

Principle P = $200

t = 1.5 years

To determine

Interest rate r = ?

Using the formula

$P = Irt$

$r=\frac{I}{Pt}$

susbtituting I = 18, t = 1.5 and P = 200

$r=\frac{18}{\left(200\times 1.5\right)}$

$r = 0.06$

r = 6% ∵ 0.06 × 100 = 6%

Therefore, we conclude that the interest rate required to accumulate simple interest of $18.00 from a principal of $200 over 1.5 years is 6% per year.

Question 2)

Given

Interest I = $60

Principle P = $750

Interest rate = 4% = 0.04

To determine

Time period t = ?

Using the formula to calculate the time period

$P = Irt$

$t\:=\:\frac{P}{Ir}$

$t=\frac{60}{\left(750\times 0.04\right)}$

$t = 2$ years

Therefore, the time required to accumulate simple interest of $ 60.00

from a principal of $ 750 at an interest rate of 4% per year is 2 years.
