Factor 10b-25b^3 please answer asap
fredd [130]

Answer:

5b(2 - 5b²)

Step-by-step explanation:

Simply take out GCFs to factor out the expression:

Step 1: Factor out GCF of 5

5(2b - 5b³)

Step 2: Factor out GCF of <em>b</em>

5b(2 - 5b²)

We can't factor the quadratic any further so that is our final answer.

Gordon types 43 3/4 pages in 3 1/2 hours. What is his rate in pages per hour
Olegator [25]

Answer:

His rate is 12 1/2 pages per hour.

Step-by-step explanation:

Given that,

Gordon types 43 3/4 pages in 3 1/2 hours or Gordon types 175/4 pages in 7/2 hours./ We need to find its rate in pages per hour. So,

R=\dfrac{\dfrac{175}{4}\ \text{pages}}{\dfrac{7}{2}\ \text{hour}}\\\\R=\dfrac{175}{4}\times \dfrac{2}{7}\\\\R=12.5\ \text{pages per hour}\\\\R=12\dfrac{1}{2}\ \text{pages per hour}

Hence, his rate is 12 1/2 pages per hour.

If x=10, find m∠WYZ<br><br> Will choose brainliest
Norma-Jean [14]

Answer:

23˚

Step-by-step explanation:

If x = 10, then angle VYZ = 157 by basic algebra. Knowing that VYZ and WYZ are supplementary angles, we can do 180-157 to find angle WYZ. 180-157 = 23˚

A line with slope 3 passes through the point (0,10). What is the y-coordinate of the point on the line with x-coordinate 2?
lana [24]
Hello!

So to find the y-coordinate we need an equation for the line. The equation we can use is

y = mx + b

In this we already know m(the slope which is 3) and we can find b by plugging in the points that are given.

10 = 3(0) + b
10 = 0 + b
10 = b

So now that we've found b, we can use this in our equation

y = 4x + b

So now we can plug in the x-coordinate that we know (2) and find the y - coordinate.

y = 4(2) + 10
y = 8 + 10
y = 18

18 is your y-coordinate
