Answer:
145) A
146) C
147) B
148) D
Step-by-step explanation:
_____________________145_____________________
Starting with number 145 it mentions that XY = 24 and XY:YZ = 1:2.
XY:YZ means ratio of XY over YZ so for each 1 XY there is 2 YZ.
Moving on and taking note that XY=24 so this means that,
[tex]\frac{XY}{YZ} =\frac{24}{YZ}= \frac{1}{2}[/tex]
Solving the above expression by cross multiplying 24x2 will give you YZ = 48. The same method applies to #146 and #148 the next questions.
_____________________146_____________________
YZ = 9 and XY:YZ=2:3
[tex]\frac{XY}{YZ} =\frac{XY}{9} =\frac{2}{3}[/tex]
XY= (2x9)/3 = 6
XY = 6
_____________________147_____________________
Given:
XZ = 2ft
YZ = 18in
In this question, you will have to refer to the proportion line given above the questions. It mentions that XZ = 2ft (which is the whole line) and YZ = 18in (which is from Y to Z). Take note that the units are not the same.
They're looking for XY which is the only unknown length in the given proportion line. To get XY you'll have to subtract XZ - YZ, but the units are not the same so you'll have to convert feet to inches since the answer options are given in inches.
Convert 2ft to inches:
To convert from feet to inches you'll have to multiply by 12 so 2x12 = 24.
Therefore, XZ = 24in
Now we subtract:
XZ - YZ = XY
24 - 18 = 6in
_____________________148_____________________
YZ = 1ft
XY: YZ = 1:4
YZ is given in feet and the answers are provided in inches so we'll have to convert.
1 x 12 = 12in
YZ = 12in
[tex]\frac{XY}{YZ} =\frac{XY}{12} =\frac{1}{4}[/tex]
XY = (1x12)/4 = 3in

An international company has 23,200 employees in one country. If this represents 26.7% of the company's employees, how many employees does it have in total?
Round your answer to the nearest whole number.
Answers
Answer:
Total number of employees = 86,891 employees
Step-by-step explanation:
Let
x = total number of employees
26.7% of x = 23,200
26.7/100 * x = 23,200
0.267 * x = 23,200
0.267x = 23,200
x = 23,200/0.267
x = 86,891.385767790
approximately 86,891 employees
Total number of employees = 86,891 employees

The Grand Old Duke of York had 10 000 men. He lost 10% of them on way to the top of
the hill, and he lost 15% of the rest as he marched them back down the hill.
What percentage of the 10 000 men were still there when they reached the bottom of
the hill?
Answers
Answer:
76.5%
Step-by-step explanation:
He lost 10% of them on way to the top of the hill
10% of 10,000 men
= 0.1 * 10,000
= 1,000 men
Remaining men = 10,000 - 1,000
= 9,000 men
15% of the rest as he marched them back down the hill.
15% of 9,000 men
= 0.15 × 9000
= 1,350 men
Total men remaining = 9000 - 1,350
= 7,650 men
% remaining =
x% of 10000 men = 7,650
x/100 * 10,000 = 7,650
Cross product
10,000x =7,650 * 100
10,000x = 765,000
x = 765,000/10,000
= 76.5%
x = 76.5%

A family of 10 that all leave the house at the same time each morning has two bathrooms. They must share for everyone to be ready. Time is allotted to each family based on age. Is this apportionment or not apportionment?
Answers
Answer:
Not apportionment
Step-by-step explanation:
Apportionment can be described as a way of sharing out or dividing out in the best fair method.
If a family of 10 leave the house at the same time and have to share just two bathrooms, the time allocation should not be based on age rather should be based on how early each person wakes up in the morning.

Students at Garcia Middle School took a survey about their favorite school.The results showed that 182 students rated pizza as their favorite food. This number represented 68% of the number of students who took the survey.What was the total number of students that took the survey?
Answers
Answer:
267.64 students
Step-by-step explanation:
Let the total number of students that took the survey be represented as x
This number represented 68% of the number of students who took the survey.
The results showed that 182 students rated pizza as their favorite food.
Therefore:
68% × x = 182 Students
68/100 × x = 182
68x/100 = 182
Cross Multiply
68x = 182 × 100
x = 182 × 100/68
x= 267.64705882 students
Therefore, the total number of students that took the survey is Approximately 267. 64 students

P and Q form a linear pair if m P=(7x-4) and m Q =(2x-5) find the measure of each angle
Answers
Answer:
Answer:
Angle P = 143º
Angle Q = 37º
Step-by-step explanation:
Linear pair means the angles add up to 180º
So, using this, set up the equation: 7x - 4 + 2x - 5 = 180
Combine Like Terms
9x - 9 = 180
Add on both sides
9x = 189
Divide
189/9 = 21
Substitute 21 for x
Angle P: 7(21) - 4
Angle Q: 2(21) - 5

area of rectangle = 15 × 6 = 90 cm²
The triangle has dimensions , base = (15 - 9) = 6 cm and height = (11 - 6) = 5 cm

One month Sam rented 3 movies and 8 video games for a total of $55 . The next month he rented 5 movies and 2 video games for a total of $18 . Find the rental cost for each movie and each video game.
Answers
Answer:
Step-by-step explanation:
You are trying to find the values of two quantities, so you will need to set up a system of two equations in two variables. We'll call M the price of a movie and V the price of a video game.
The first month: 3 movies, 8 video games, $55. Let's translate this into algebra:
3M + 8V = 55
The second month: 5 movies, 2 video games, $18. Translated:
5M + 2V = 18
Solve that system of equations

Amaka buys 4 rulers and a pencil and these cost the same as 2 rulers and 4 pencils. If a pencil cost #8, how much does a ruler cost?
Answers
Answer: ruler cost $12
Step-by-step explanation:
step 1
Let cost of ruler be represented as r
and cost of pencil be represented as p
we were given that
4 rulers and a pencil and these cost the same as 2 rulers and 4 pencils which is expressed as
4r + p = 2r+ 4p
and cost of pencil= $8
therefore
sTEP 2--- Solving
4r+ 8 = 2r+ 4 x8
4r+ 8 = 2r+ 32
4r - 2r= 32-8
2r= 24
r= 24/2 = r= $12
