Find the areas of the trapezoids.
Answer:
A = 12 units ^2
Step-by-step explanation:
The area of the trapezoid is found by
A = 1/2 (b1+b2)h
b1 = 2
b2 = 4
h = 4
I found these by looking at the graph
A = 1/2(2+4) 4
A = 1/2(6*4)
A = 12 units ^2
if it takes 5 men 20hours to brick a house, how long will it take 2 men to do the job if they work at the same rate?
To find the contribution of each man (this is a sexist problem as women could work as well, but that’s besides the point) take 5/2 and then multiply that value by 20 and you’ll find it takes 50 hours for two men to do it.
Answer: 50 hours
Answer:
50 hours.
Step-by-step explanation:
To solve these type of question we should always remember that man power is inversely proportionate to the work done.
That means if we double the manpower work done will be half. and when we reduce the manpower to the half time take to complete the work will be double.
It takes 5 men to brick a house = 20 hours
so 1 man will brick the house = 20 × 5
= 100 hours
Therefore, 2 men will brick the house = [tex]\frac{100}{2}[/tex]
= 50 hours.

ANSWER
[tex]y = 3x - 3[/tex]
EXPLANATION
Let
[tex]y = mx + c[/tex]
be the equation.
We can choose any two ordered pairs to determine the equation of the relation.
[tex](6,15) \: and \: (8,21)[/tex]
We find m using the formula;
[tex]m = \frac{y_2-y_1}{x_2-x_1} [/tex]
[tex]m = \frac{21 - 15}{8 - 6} = \frac{6}{2} = 3[/tex]
The equation becomes
[tex]y = 3x + c[/tex]
When x=6, y=15.
This implies that,
[tex]15 = 3(6) + c[/tex]
[tex]15= 18 + c[/tex]
[tex]15 - 18= c[/tex]
[tex]c = -3[/tex]
The equation of the relation is therefore,
[tex]y = 3x -3[/tex]
Please explain how to find QP on the attached drawing. Thanks!
Answer:
QP = 6
Step-by-step explanation:
We are given a line MP with a point on it Q and we are to find the length of the line segment QP.
We know that the length of MP is [tex] x + 17 [/tex], MQ is [tex]3[/tex] and QP is [tex] 2 x + 22 [/tex] so we can write it as:
[tex]MP=MQ+QP[/tex]
[tex]x+17=3+2x+22[/tex]
[tex]2x-x=17-22-3[/tex]
[tex]x=-8[/tex]
Substituting this value of x to find the length of QP:
QP = [tex] 2x +22 = 2(-8) +22 = [/tex] 6
20) Use the distributive property to factor the expression. 10xz − 20yz
A) z(10x − 20y)
B) 10(xz − 2yz)
C) 10z(x − 2y)
D) xyz(10 − 20)
Answer:
C. 10z(x - 2y)
Step-by-step explanation:
10xz − 20y
Factor the terms
Factors of 10xz = 2 × 5 × x × z
Factors of -20yz = (-1) × 2 × 2 × 5 × y × z
Identify their greatest common factor
The common factors are 2, 5, and z. The greatest common factor is 10z.
Rewrite them with the GCF as a factor
10xz = 10z × x
-20yz = 10z × (-2y)
Replace the terms in the original expression with the factored terms
10xz − 20yz = 10z(x) + 10z(-2y)
Use the distributive property to isolate the greatest common factor
10z(x) + 10z(-2y) = 10z(x - 2y)
Answer:
C. 10z(x - 2y)

Michelle took a survey of the students in her grade to see how many are likely to join a book club if she starts one. She surveyed 48 students and 10 said they would join. If there are 240 students in her grade, about how many students could Michelle expect to join the book club?
Answer: 50
Step-by-step explanation: First of all, you need to establish your rate of acceptance. This would be 10 out of 48 or 10/48. Next, you need to simplify this to 5/24. Okay now this is epic. Now you need to convert 5/24 to x/240. Simple. Just multiply both sides by ten in 5/24 and you get your answer of 50. Very cool.
Final answer:
Michelle can expect approximately 50 students to join her book club based on the proportion of surveyed students who expressed interest.
Explanation:
Michelle surveyed 48 students, and 10 said they would join the book club. To estimate how many out of the total 240 students might join, we use proportions. The first step is to set up a proportion with the numbers Michelle has provided and then solve for the unknown:
Number of students surveyed who would join / Total students surveyed = Expected number who would join / Total students in grade
10 / 48 = x / 240
To find x, multiply both sides by 240:
240 * (10 / 48) = x
Then solve for x:
x = 50
Thus, Michelle could expect about 50 students to join the book club.

What is the percent of decrease from 10 to 3?
Write your answer using a percent sign (%).
The percent of decrease from 10 to 3 can be calculated by finding the difference between the two numbers, dividing this difference by the original number, and multiplying the result by 100. This method gives us a decrease of 70%.
Explanation:The question is looking to find the percent of decrease between two numbers, specifically from 10 to 3. To calculate this, we first find the difference between the two numbers (which is 10 - 3 = 7), then divide this difference by the original number (7 divided by 10 equals 0.7) and finally multiply the result by 100 to convert it to percentage form. This gives us a 70% decrease.
Here are the step-by-step calculations:
Find the difference between the two numbers: 10 - 3 = 7.Divide the difference by the original number: 7 / 10 = 0.7.Multiply the result by 100 to convert to a percentage: 0.7 x 100 = 70%.So, the decrease from 10 to 3 is 70%.

Set up a proportion
36/150 =x/350
Cross multiply then divide
Answer:
84 people wear blue jeans.
Step-by-step explanation:
This is the same out of questions that are multiples of each other, except we have to use decimals. 350/150 is 7/3, so we know in order to get 350 with 150, we need to multiply 7/3. Now, we multiply 36 by 7/3 to get 84 as our answer
What are four common denominators for 1/4 & 1/2
I am pretty sure that it is 8,12,16 and 20
if not plz forgive me
The common denominators for 1/4 and 1/2 are:
8421These denominators are found by identifying the multiples of the denominators of 1/4 and 1/2.
The question at hand involves finding four common denominators for the fractions 1/4 and 1/2. A common denominator is a shared multiple of the denominators of two or more fractions. This task is essential for operations like addition, subtraction, or comparison of fractions.
4: This is the most obvious choice since 4 is the denominator of one of the fractions, and 2 is a factor of 4. Hence, 1/2 can be expressed as 2/4.
8: Doubling the first common denominator gives us 8. In this case, 1/4 becomes 2/8 and 1/2 is 4/8.
12: Multiplying the denominators 4 and 2 gives us another common denominator, 12. Thus, 1/4 can be expressed as 3/12 and 1/2 as 6/12.
20: Choosing a higher number that is divisible by both 4 and 2. Here, 1/4 is 5/20 and 1/2 becomes 10/20.
These examples show how to scale the numerators accordingly to maintain the value of the original fractions while having the same denominator.

ABEF=CBED. The perimeter of CBED is 17. Find the length of BE
2.7. Because of the CPCTC theorem, like CB is equal to 5.9 so if you add the lengths of CB, CD, and ED and subtract this by 17, you find the length of BE which is 2.7
Answer:
Option B, 2.7 is the answer.
Step-by-step explanation:
Perimeter of CBED = CD + ED + BC + BE
17 = 5.6 + 2.8 + 5.9 + BE
[Since ABEF ≅ CBED so AB = BC = 5.9]
Now 17 = 14.3 + BE
BE = 17 - 14.3
= 2.7
Therefore, Length of BE = 2.7
Option B, 2.7 is the answer.
In the same circle, chord AB determines a 115° arc and chord AC determines a 43° arc. Find m∠BAC.
Answer:
36° or 101°
Step-by-step explanation:
Consider the figures given in the attachment.
Point C can be between A and B as shown in the left image of the attachment or outside AB chord as shown in the right image.
In both figures, ∠AOB = 115° and ∠AOC = 43°.
Both the triangles are isoceles triangle as OC and OA side is equal in ΔAOC and OA and OB is equal in ΔAOB.
In ΔAOC,
∠A + ∠O + ∠C = 180°
∠A = ∠C
∴ 2 ∠A =180-43=137°
∴∠A = 68.5
In ΔAOB,
∠A + ∠B + ∠O = 180°
∠A = ∠B
∴2 ∠A = 180-115=65°
∴∠A = 32.5°
For figure on the left side,
∠BAC = ∠OAC - ∠OAB = 68.5 - 32.5 =36°
For figure on right side,
∠BAC = ∠OAC + ∠OAB = 68.5 + 32.5 =101°

If y = 2x - 1 and (3, 5) and (4, 7) are part of the pattern then what is the y coordinate of (5, __ )? A) 8 B) 9 C) 10 D) 11
Answer:
(5, 9)
Step-by-step explanation:
Substitute the x- coordinate of the point into the equation to evaluate the y- coordinate, that is
x = 5 : y = (2 × 5 ) - 1 = 10 - 1 = 9 → B
Hence the coordinates of the point are (5, 9 )
Final answer:
Using the equation y = 2x - 1, the y-coordinate for the point (5, __) is calculated to be 9 by substituting x = 5 into the equation, resulting in the value that fits the identified pattern.
Explanation:
The question asks for the y-coordinate of the point (5, __) based on the pattern described by the equation y = 2x - 1. We see that the given points (3, 5) and (4, 7) fit this pattern, as plugging x = 3 into the equation gives y = 2(3) - 1 = 5, and plugging x = 4 into the equation gives y = 2(4) - 1 = 7. To find the y-coordinate for the point where x = 5, we can follow the same arithmetic pattern.
Using the equation, we plug in x = 5:
y = 2(5) - 1
= 10 - 1
= 9
Therefore, the y-coordinate for the point (5, __) is 9, which corresponds to option B.
