5x + 2(x + 7) = 14x – 7 The first one to answer gets brainalist. Social Test.
Answer:
The answer is True.
Step-by-step explanation:
Step 1: Evaluate the left side of the equal sign:
5x + 2(x + 7) = 14
Step 2: Evaluate the right side of the equal sign:
14x–7 = 14
Step 3: Determine if the true-false equation is true or false:
Since 14 = 14, then 5x + 2(x + 7) = 14x–7 is True
Brenda is training for the New York City Triathlon. She is nervous about swimming 1.5 kilometers in the Hudson River. So, she wants to make sure that she can swim that far in a swimming pool. So far, she has swum 20 laps. If each lap is 25 meters, how many more laps does she have to swim?
Answer:
she has 40 more laps to go
Step-by-step explanation:
1,500 meters are in 1.5 kilometers. So if you use this equation you´ll find the answer to how many miles she will need in total. 1,500/25=60 then subtract 20.
Three specialists can complete in 1 hour the job their 5 assistants usually do in 1 hour. Suppose eight specialists can complete a certain job 9 hours. How many assistants can complete the same job in 10 hours?
Answer:
12 assistants
Step-by-step explanation:
If 5 assistants can do in 1 hour what 3 specialists can do, you want to know the number of assistants needed to do in 10 hours what 8 specialists can do in 9 hours.
EffortThe 1-hour job tells us that how to relate the effort of assistants to that of specialists:
5 assistant·hours = 3 specialist·hours
The longer job takes 8 specialists 9 hours, so is a job requiring an effort of ...
(8 specialists)·(9 hours) = 72 specialist·hours
In terms of assistant·hours, that is ...
72 specialist·hours = 24(3 specialist·hours) = 24(5 assistant·hours)
= 120 assistant·hours = (12 assistants)(10 hours)
It takes 12 assistants to complete the same job in 10 hours.

A. -3/2
B. 2/3
C. 1
D. 3/2
Answer:
D: 3/2
Step-by-step explanation:
This is because on the Y side: It is gaining numbers by 3. On the x side it is gaining by 2. So it is 2/3. But you have to do Delta. Which now is 3/2 instead of 2/3. So to answer your question: The correct answer is hence D: 3/2.

Answer:
C. 176.6 Square feet (I think)
Step-by-step explanation:
I tried many different ways and got three of the answers above but I think this is the right one.
The equation to find area of a circular cone base: [tex]A= \pi r^2[/tex]
We are given the diameter (15 Feet) but we need to find the radius. So we use the diameter to radius formula: [tex]r = \frac{d}{2}[/tex]Plug in numbers: [tex]r=\frac{15}{2}[/tex] ≈ [tex]7.5[/tex]Use the Area formula now that you have radius: [tex]A=\pi 7.5^2[/tex]Solve and get = [tex]a = 176.71458676[/tex]Looking at the options the closest one to our answer (off by one-tenth) is C.Sorry if you get this wrong. I tried lol.

This line graph shows how the temperature changed during one week.
What was the difference between the highest temperature and the lowest temperature during the week?
Answer:
25°C
Step-by-step explanation:
The highest temperature in the week was recorded on Monday, at 16°C.
The lowest temperature in the week was recorded on Friday, at -9°C.
To find our answer, we must set up a subtraction problem to find the difference between the two.
16 - (-9) = 25
Here is a triangular prism
All measurements are in centimeters
Calculate the volume and surface area of the prism.
Answer:
Volume = 42 cm^3, Surface Area = 96 cm^2
Step-by-step explanation:
Volume = Area * Height
S = semi-perimeter or half of the perimeter
Area of the triangle using heron's formula = [tex]\sqrt{s(s-a)(s-b)(s-c)}[/tex]
S = (3 + 4 + 5)/2 = 6 cm
Area of triangle = [tex]\sqrt{6(6-3)(6-4)(6-5)}[/tex]
= [tex]\sqrt{6 * 3 * 2 * 1}[/tex]
= [tex]\sqrt{36}[/tex]
= 6 cm^2
Volume = 6 * 7
= 42 cm^3
Surface Area = Area of bases * Area of Lateral faces
Area of lateral faces = 7 * 3 + 7 * 4 + 7 * 5 = 84 cm^2
Area of bases = 6 cm^2 * 2 = 12 cm^2
Surface area = 12 cm^2 + 84 cm^2 = 96 cm^2

Step-by-step explanation:
I worked hard lol so pls mark
3. The question is in the picture.
Answer:
No
Step-by-step explanation:
The reason for this is that the line is not increasing by 1.5. If we take the 2 y values which are 20 and 10. 20-10 is 10 and if we take the 2 x values and subtract them, we would get 30-15 which is 15. Now divide the y value and the x value (10/15) and we would get 0.66666.... Which is not 1.5. This was probably done because he mixed up the x values and y values which would be 15/10 and a common mistake when reading a coordinate plane. This does show a proportional relationship because the line is constant and therefore proportional. Hope this helps!

What is the volume of a cylinder with a radius of 4 and a height of 9?
-----
A. 13π
B. 36π
C. 72π
D. 144π
Answer:
144.1π cubic units
Step-by-step explanation:
Utilize the volume formula V = (pi)r^2h, where r is the radius and h is the height:
Here V = (pi)(4^2)(9) ≈ (22/7)(16)(9) ≈ 144.1π

Answer: [tex]4\sqrt{3}[/tex] (choice A)
========================================
Work Shown:
[tex]\sqrt{48} = \sqrt{16*3}\\\\\sqrt{48} = \sqrt{16}*\sqrt{3}\\\\\sqrt{48} = 4\sqrt{3}[/tex]
The idea is to factor 48 such that one of the factors is the largest perfect square possible. So that's why we go with 48 = 16*3. Then we use the rule [tex]\sqrt{x*y} = \sqrt{x}*\sqrt{y}[/tex] to break up the root.
