There were 3,496 parts in total that were tooled by the machine.

Assuming the total number of parts tooled is x, that means that 1/8 of x is 437 parts because that was the proportion of the total that was rejected.

To find the total number of parts therefore, use the formula:

Proportion of rejects × x = Number of parts rejected

1/8 × x = 437

1/8x = 437

x = 437 ÷ 1/8

x = 437 x 8

x = 3,496 parts

In conclusion, there was 3,496 parts.

A plane in R 3 is a subspace generated by two nonlinear vectors. Let P be the plane in R 3 that goes through the points (0, 0, 0

balandron [24]

Answer:

Yes, it lies on the plane

Step-by-step explanation:

Note that the generator (1,2,0) will always make vectors whose third coordinate is always 0. In order to obtain a 4 in the third coordinate, we need to use the generator (0,0,1). Specifically, we need (0,0,1) to be multiplied by 4, if we do that we obtain 4*(0,0,1) = (0,0,4).

We still need to obtain (3,6,4)-(0,0,4) = (3,6,0) from the generator (1,2,0), which is possible because (3,6,0) = 3*(1,2,0). Therefore

3*(1,2,0) + 4 *(0,0,1) = (3,6,4)

Thus, the point (3,6,4) is generated by the two vectors and, as a result, this points lies in the plane.

What is 5/10 + 8/100

Greeley [361]

Answer:

$\frac{29}{50}$

Step-by-step explanation:

We have two fractions and are being asked to add them both.

5/10 and 8/100 don't have the fractions, but 5/10 can be simplified to 1/2, meaning that to make the same denominator, we have to find the half of 100, which would be 50. Now turn the fraction into 50/100.

50/100 + 8/100

58/100

This can be simplifed :

$\frac{58/2}{100/2}$

$\frac{29}{50}$
