Answer:

Danielle is 7 and her counselor is 21

Step-by-step explanation:

Let x be the age of Danielle and y be the age of her counselor then:

y=3x

x+y=28

We can solve this using substitution. In this case, substitute 3x for y since y=3x...

x+3x=28

   4x=28

Divide both sides by 4 (division property of equality)

x=7

y=3x=3(7)=21

Danielle is 7 and her counselor is 21

Which answer choice is equivalent to the expression 3x-1/2?
alex41 [277]

You can substitute a number in for x and compare the answer choices (not the most efficient way but it's how I would do it). Let's just say x = 5. Then the expression would equal 0.25819889. Substitute 5 in for x is the answer choices and see which one is the same.

A) simplified is 0.004 repeating

B) simplified is 0.25819889

C) simplified is 0.12

D) simplified is 1.341640786

We can see that B is the right answer

Bess [88]

Answer:

$37,500

Step-by-step explanation:

We have been given that a house worth $180,000 has a coinsurance clause of 75 percent. The owners insure the property for $101,250. They then have a loss that results in a $50,000 claim.

We will use loss settlement formula to solve our given problem.

\text{Loss settlement}=\frac{\text{Loss}\times\text{Limit of insurance}}{\text{Actual cash value}\times \text{Coinsurance}\%}

Upon substituting our given values, we will get:

\text{Loss settlement}=\frac{\$50,000\times\$101,250}{\$180,000\times 75\%}

\text{Loss settlement}=\frac{\$50,000\times\$101,250}{\$180,000\times 0.75}

\text{Loss settlement}=\frac{\$5,062,500,000}{\$135,000}

\text{Loss settlement}=\$37,500

Therefore, they will receive $37,500 from insurance.

In right triangle KLM, KL =14 and angle L=30° and angle M=90°. Find KM. Leave your answer in the simplest radical form.
salantis [7]

Answer:

KM = 7 Units

Step-by-step explanation:

In the given structure ΔKLM

∠KLM = 30° and side KL = 14 and ∠KML = 90°

and we have to find the measurement of KM.

From right angle triangle KLM

Side Sin30° = KM/KL = KM/14

KM = 14×sin30° = 14×1/2 = 7

So the answer is KM = 7 Units
