10. A rectangle has width the same as a side of a square whose perimeter is 20 m. the length
of the rectangle is 9 m. Find the perimeter of this rectangle.
Answer:
The perimeter of the rectangle is 28m
Step-by-step explanation:
Perimeter of a square = 4 x side length
20 = 4 x side length
side length = 20/4 = 5m
width of rectangle = 5m
length of rectangle = 9m
Perimeter of rectangle = 2(l + w)
= 2(9 + 5)
= 2(14)
= 28m

A group of friends in Chicago watched a televised bullfight. They ordered 3 pizzas ($15 each), 15 drinks ($1.50 each), and 6 large nachos ($5.80 each). After adding 5% and a 20% tip to the total, what did they pay for the food? (The tip is 20% of the total before the tax is added) around the answer to the nearest while cent
Answer:
$127.875
Step-by-step explanation:
cost of 3 pizzas= $15*3
cost of 3 pizzas=$45
cost of 15 drinks=$1.50*15
cost of 15 drinks=$22.5
cost of 6 nachos=$5.80*6
cost of 6 nachos=$34.8
Total cost = pizza cost+ drinks+nachos
total cost=$45+$22.5+$34.8
total cost=$102.3
Now ,
Tip cost=$102.3*20%
=$20.46
tex cost=$102.3*5%
=$5.115
Bill which all friends pay=total cost+ tip cost+tex cost
= $102.3+$20.46+$5.115
=$127.875
4 Times the sum of a number and 6 is 5 less than 3 times the same number. write an equation and solve for the number
Answer:
-29
Step-by-step explanation:
4× (x+6) = -5. + 3x
4 times the sum of a number is 5 less than 3 times the same number
4×(x+6) = 3x - 5
4x + 24 = 3x - 5

find the defference between 5 2/7 and 2 2/4
Answer: 39/14
Step-by-step explanation:
Given
5 2/7 - 2 2/4
Convert mixed fraction to improper fraction
5 2/7 = (5 × 7 + 2) / 7 = (35 + 2) / 7 = 37/7
2 2/4 = (2 × 4 + 2) / 4 = (8 + 2) / 4 = 10 / 4 = 5/2
Find the common denominator for 37/7 and 5/2
First 10 multiples of 2 = 2, 4, 6, 8, 10, 12, 14, 16, 18, 20
First 5 multiples of 7 = 7, 14, 21, 28, 35
Since 14 is the first common multiple in the lists, 14 would be the common denominator of 37/7 and 5/2
Convert to the common denominator
(37 × 2) / (7 × 2) = 74 / 14
(5 × 7) / (2 × 7) = 35 / 14
Simplify by subtraction of numerator
=74/14 - 35/14
=(74 - 35) / 14
=[tex]\boxed{\frac{39}{14} }[/tex]

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?
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%

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
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.

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

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.

A bike rental shop rents out bicycles with a flat rate of $6 and then charges $2 per hour a person rents out the bike. Identify the independent variable and the dependent variable. Then write an equation relating the cost, C, to the number of hours the bicycle was rented.
Independent Variable:
Dependent Variable:
Equation:
Answer:
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.

Step-by-step explanation:
The equation modeled by this throw is
-16t^2+8t+2
Using the vertex x coordinate formula of -b/2a,
we find that the x coordinate of the vertex is 0.25. Subbing 0.25 seconds for t into -16t^2+8t+2, we find out that the y value of the vertex is 3. This means the highest point reached by the ball is 3 feet and this takes 0.25 seconds

Greatest common factor is 6. If you use the distributive property then the answer would be 6(4) + 6(6) or 6(4+6). Then you distribute the 6 to each digit and should get 24+36.
calculate the absolute value
| 4 - 3x | = 5x + 4
Recall the definition of absolute value:
• |x| = x if x ≥ 0
• |x| = -x if x < 0
So we have 2 cases to consider:
• If 4 - 3x ≥ 0, then |4 - 3x| = 4 - 3x, and we have
4 - 3x = 5x + 4
8x = 0
x = 0
• If 4 - 3x < 0, then |4 - 3x| = -(4 - 3x) = 3x - 4, which gives
3x - 4 = 5x + 4
2x = -8
x = -4
However, keep in mind that |x| is always non-negative. If x = -4, then the right side of the equation becomes
5(-4) + 4 = -20 + 4 = -16 < 0
so the solution in this case is extraneous.

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]
