Yes, 80 pairs. If you add the 8 pairs back on to 292 it will equal 300. Add a zero to that 300 and the 8, and there's your answer. 80 pairs defective.

$8+292=300$

8 out of 300 were defective.

$\frac{8}{300}=\frac{x}{3000} \\ \\ 8*3000=300*x \\ \\ 24000=300x \\ \\ 80=x$

80 pairs were defective

Usimov [2.4K]

The old photocopier can make x manuals in an hour. The new photocopier can make 4x. Combined, they made 5x manuals in an hour.

In one hour they can make 1/28 of the manuals.

1/(28*5)=1/140 is the rate.

The new photocopier can make all the manuals in 4/140 or 35 hours.

The old one can make them in 140 hours.

Help.................??

Irina-Kira [14]

Distribute it out. you should end up with (y^2+7y) + (5y+35) add the 7y and the 5y to get 12y. you will have y^2+12y+35. tbh i have no idea what to do from there. its been so long since i have studied this

Ann [662]

Answer:

Step-by-step explanation:

We know that a triangle equals to 180 degrees.

(2x+24)+(4x+43)+(x^2+1)=180

the awnser to this is x=8.

You plug in 8 into x

Angle 1: 2(8+24) --> 40

Angle 2: 4(8+43) -->75

Angle 3: (8^2+1) -->65

Check your work: add values together 40+75+65=180

Please help solve this, I’ve tried my best. My answers are a height of 6.7 using 30-60-90 as a last resort, and the glass volume

Neko [114]

Answer:

A) To ensure the correct and exact straight height

B) 15 inches

C) 24.87 in $^{3}$

Step-by-step explanation:

Hello! Lets start!

First, it asks us to explain why the two bases must be parallel. In order to measure the correct and exact height, we must be sure that the bases are parallel, or else there would be a range of heights; in order to ensure that you are measuring a straight distance, they must be parallel!

Second, it asks us to identify the height of cone. To do this, we must make a slope! We can see that, for every time we go down 5 inches, we lose 1 inch of our base! Our slope in this situation would be -5. So, lets continue to see how long before the cone reaches its tip, in which the base would be equal to 0. At 5 inches, our base is 2 inches. At 10 inches, our base is 1 inch. At 15 inches, we do not have a base, as it equals 0! So therefore, our cone height is 15 inches.

Third, it asks us to identify the volume of the cup, which is also called a <em>circular truncated cone. </em>To do so, we can use the formula:

₁ $V = \frac{1}{3} \pi (r_{1}^2 + r_{1}r_{2} + r_2^2)h$

Lets plug in our information!

$V = \frac{1}{3} \pi (1.5^{2} + (1.5)(1) + 1^{2}) (5)\\V = 24.87$

Hope this helps! Remember, math is fun!
