In a shipment of 400 parts, 14 are found to be defective. How many parts out of 1000 would NOT be defective?
Can you please show a proportion I am confused.
Answer:
965 parts would not be defective.
Step-by-step explanation:
So for every 400 parts, 14 are defective. That means 386 are not defective. 1000 is 2.5 times as many as 400. So multiply 386 by 2.5 to get your answer.
386/1 * 5/2
193/1 * 5/1
965/1
That means for every 1000 parts, 965 would not be defective. The proportion(s) would be 386:400/965:1000 here.

Solve for x. Show each step of the solution.
0.75 (x + 16) = 3 – 0.5 (x-8)
Answer:
x= 18.29
Step-by-step explanation:
- distribute then simplify- .75x + 12 = 2.5x - 20
- subtract .75x from each side- 12 = 1.75x - 20
- add 20 on each side- 32 = 1.75x
- divide each side by 1.75x- x= 18.29
not 100% sire if thats correct
[tex]0.75\left(x+16\right)=3-0.5\left(x-8\right)[/tex]
[tex]0.75\left(x+16\right)\cdot \:100=3\cdot \:100-0.5\left(x-8\right)\cdot \:100[/tex]
[tex]75\left(x+16\right)=300-50\left(x-8\right)[/tex]

A model train takes 10 seconds to travel
along a section of track that is 5 yards long.
At this rate, how many feet does the model
train travel every minute? Show your work.
The speed is the distance covered by an object at a particular time. The distance that the train model will cover in a minute is 30 yards.
What is speed?The speed is the distance covered by an object at a particular time. Therefore, it is the ratio of distance and time.
Speed = Distance Covered / Time taken
Given that a training model takes 10 seconds to travel 5 yards. Therefore, we can write,
Speed of the trian = 5 yards / 10 seconds = 0.5 yards per second
Now, the distance that train model will cover in a minute is,
Distance = Speed × Time
= 0.5 yards per second × 1 minute
= 0.5 yards per second × 60 seconds
= 30 yards
Hence, the distance that train model will cover in a minute is 30 yards.

In the xy-plane, a line segment is dilated by a scale factor of 2. The dilation is centered at a
point not on the line segment. Select from the drop-down menus to make a true statement about the line segment and its image. The like segments are choose, and the length of the image is choose the length of the original line segment
The line segments are parallel and the length of the image is perpendicular to the length of the original line segment.
Why is the line segment by a scale factor. ?The line segment is a part of the line and is bounded by the two distinct endpoints. The line segment that represents the x, y plane is dilated by a factor of 2 and this dilation is centered around the point and not a line. Hence are line segment is parallel and perpendicular to the length of the original point shown in the image.

3(r-1) -2(r+3) =0 anybody know the answer to that ?
Answer:
r = 9
Step-by-step explanation:
3(r - 1) - 2(r + 3) = 0
First, use the distributive property.
3r - 3 -2r - 6 = 0
Now, isolate the variable "r" to one side by adding the opposite of the whole numbers to each side so it cancels it out on the left ide and adds it to the right.
3r - 3 -2r - 6 = 0
+3 +6 +3 +6
3r - 2r = 9
Subtract the r's.
r = 9
Now that we know r = 9, we can plug in 9 into the original (but distributed) expression for every time it uses the variable "r" to check our work.
3r - 3 -2r - 6 = 0
3(9) - 3 - 2(9) - 6 = 0
27 - 3 - 18 - 6 = 0
24 - 24 = 0
0 = 0
So, r = 9 is true.

Find the value of each variable. Write answers in simplest radical form.
Answer:
The value of n is 6.
Step-by-step explanation:
Given that these 2 triangles form a square so we can assume that all sides are same. Then, we have to apply Pythagoras Theorem, a² + b² = c², where a, b are sides and c is hypotenuse :
n² + n² = (6√2)²
2n² = 6² × (√2)²
2n² = 72
n² = 72 ÷ 2
n² = 36
n = √36
n = 6
