The simplified expression of the perimeter of the given triangle is 10y + 1

Use the concept of a triangle defined as:

A triangle is a three-sided polygon, which has three vertices and three angles which has a sum of 180 degrees.

In the given figure:

Hypotenuse = 6y

Perpendicular = 3y + 5

Base = y - 4

The perimeter of a triangle = Hypotenuse + Perpendicular + Base

Therefore,

Perimeter of the triangle = 6y + 3y + 5 + y - 4

Perimeter of the triangle = 10y + 1

Hence,

The perimeter of the triangle is 10y + 1.

An angle has a measure of n degrees. Which of the following expressions would be used to find the measure of its complement?
a. n - 90
b. 90 -n
c. 180 - n
d. n - 180

Answers

9514 1404 393

Answer:

b. 90 -n

Step-by-step explanation:

The sum of an angle and its complement is 90 degrees. If c represents the complement, this means ...

n +c = 90

c = 90 -n . . . . . . . . . subtract n from both sides of the equation

The expression 90 -n can be used to find the complementary angle.

The manager is checking the results of the customer satisfaction surveys. The ones he has looked at have scores of 79%, 92%, 71%, and 86%. What score must be on the next survey to have a mean average of exactly 85% for the five surveys?

Answers

Answer:

97%

Step-by-step explanation:

for such a question we can use the percentage numbers like real unit numbers, as we need to analyze just the percentage numbers and align them with another percentage number with the result of another percentage number.

so, we just use the percentage numbers and deal with mean values and such like with real unit numbers.

therefore we need to find x

(79 + 92 + 71 + 86 + x) / 5 = 85

as the sum of all numbers divided by the number of measurements is the mean value.

and so,

79 + 92 + 71 + 86 + x = 425

328 + x = 425

x = 97

so, the next site must be 97%, so that the average for the 5 surveys will be exactly 85%

How many ways can you make change for 60¢ using only nickels, dimes, and quarters?

Answers

You can make 60cents using nickels dimes and quarters about 10 or more times

There are 13 ways to make change for 60¢ using only nickels, dimes and quarters.

Determination of the number of combinations for a given amount of money

In the United States of America, a nickel equals 0.05 dollar, a dime equals 0.10 dollar and a quarter equals 0.25 dollar.

For 0.60 dollar we have the following expression in terms of nickels ([tex]n[/tex]), dimes ([tex]d[/tex]) and quarters ([tex]q[/tex]):

[tex]0.25\cdot q + 0.10\cdot d + 0.05\cdot n = 0.60[/tex], where [tex]q,\,d,\,n \in \mathbb{N}_{O}[/tex] (1)

Since quarters are the money of greatest value, we assume arbitrary quantities and count corresponding solutions, whose representations are included below:

Case 1 ([tex]q = 0[/tex])

[tex]n = 12-2\cdot d[/tex] (2)

According to the first graph, there are seven forms in this scenario.

Case 2 ([tex]q = 1[/tex])

[tex]n = 7-2\cdot d[/tex] (3)

According to the graph case_2, there are four forms in this scenario.

Case 3 ([tex]q = 2[/tex])

[tex]n = 2- 2\cdot d[/tex]

According to the graph case_3, there are two forms in this scenario.

Hence, there are 13 forms to make change for 60¢ using only nickels, dimes and quarters. [tex]\blacksquare[/tex]

The inequality - 15<-6 is given. Write the inequality you get when you perform the

Divide both sides of the inequality by 3.

Answers

Answer:

Step-by-step explanation:

-15<-6=-15

-15÷3

=-5

Inequalities are used to show unequal expressions. There are five inequalities, and they are: not equal to, greater than, less than, greater than or equal to and less than or equal to.

The inequality when both sides of [tex]-15 < -6[/tex] is divided by 3 is [tex]-5< -2[/tex]

Given that:

[tex]-15 < -6[/tex]

Divide both sides by 3

[tex]-15 \div 3< -6 \div 3[/tex]

Evaluate the division

[tex]-5< -2[/tex]

Hence, the inequality when both sides of [tex]-15 < -6[/tex] is divided by 3 is [tex]-5< -2[/tex]

Independent Variable: Number of hours

Dependent Variable: Cost

Equation: C = 2x + 6

Step-by-step explanation:

The independent variable (x) is the variable that is manipulated. In this instance, that would be the number of hours a person rents out the bike.

The dependent variable (C) is the variable that is manipulated depending on the value of the independent variable. In this instance, that would be the total cost for renting the bike.

The total equation would be C = 2x + 6. The coefficient, 2, represents the charge of $2 per hour and the 6 represents the starting charge of $6.
