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.

Answer: 904.78km^3

Step-by-step explanation:

The formula for finding the volume of a sphere is 4/3πr^3 and the radius (r) is 6km (the radius is half of the diameter) so when you put that in, you get 904.78 and your answer with volume is always cubed.

Answer: 55.

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]

[tex]75x+1200=-50x+700[/tex]

[tex]5x+1200-1200=-50x+700-1200[/tex]

[tex]75x=-50x-500[/tex]

[tex]75x+50x=-50x-500+50x[/tex]

[tex]125x=-500[/tex]

[tex]\frac{125x}{125}=\frac{-500}{125}[/tex]

Sample Response: Each base must be treated separately. Since each base is raised to a negative exponent, they should both be in the denominator of the fractions. The simplified form of the expression has 1 in the numerator and r to the 8th power times s to the 5th power in the denominator

Answer:

This is what it says to include in your response..." Each base has a negative exponent" and "Both powers should be in the denominator".

Step-by-step explanation:

This is the Exact sample response,

Each base must be treated separately. Since each base is raised to a negative exponent, they should both be in the denominator of the fractions. The simplified form of the expression has 1 in the numerator and r to the 8th power times s to the 5th power in the denominator.

Answer:

62.8 cm

Step-by-step explanation:

The equation for finding the circumference of a circle is [tex]\pi[/tex]D. To find the diameter of a circle, multiply the radius by 2. Doing this gives you the equation 20[tex]\pi[/tex]. 20 * 3.14 is equivalent 62.8 cm.

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.

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.

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.
