Answer:

128 tons can be processed in 8 hours.

Step-by-step explanation:

48 divided by 3 = 16 (to see how much tons are produced in 1 hr.)

16 x 8

  =128

Answer:

128 tons in 8 hours

Step-by-step explanation:

do 48 divided by 3 = 16      

to see how much tons get produced in an hr.

then when you do 16x8 which is 128

Answer & Step-by-step explanation:

Vertical angles are congruent meaning that these two angles are going to have the same measurement. Since we know this, then we can set up an equation where one angle is equal to the other.

x + 10 = 55

Subtract 10 on both sides of the equation.

x = 45

So, the value of x is 45.

Answer:

a in this equation would be 3/4 because...

Step-by-step explanation:

2/3a−1/6=1/3

2/3a+−1/6=1/3

2/3a+−1/6+1/6=1/3+1/6

2/3a=1/2

Multiply both sides by 3/2.

(3/2)*(2/3a)=(3/2)*(1/2)

a=3/4

Hope this helps!

Answer:

31.4 trillion decimal places but no one really knows how many decimal places there are. 31.4 trillion decimal places is a world record set by google

Step-by-step explanation:

Answer:

`31.4 trillion decimal places.

Explanation:

As far as we know Google found out that there is about 31.4 trillion decimal places which is rounded to 3.14. Google is not 100% accurate though, Pi is a mathematical number that never ends so we just use what we know which is 3.14. Pi is an ideal that in numerical terms can be approached, but never reached. In order to calculate Pi simply involves taking any circle and dividing its circumference by its diameter. William Jones is the "founder" of Pi in 1706. Jones was a British little-known mathematics teacher, Jones was the first person to use a symbol to represent the platonic concept of Pi.

Answer:

120 [tex]\frac{13}{18}[/tex]

Step-by-step explanation:

The formula for finding the volume of a prism is:

V = Bh

You have to convert 13 [tex]\frac{2}{3}[/tex] into an improper fraction, like so:

[tex]\frac{41}{3}[/tex]

Convert the other:

[tex]\frac{53}{6}[/tex]

Multiply:

[tex]\frac{41}{3}[/tex] · [tex]\frac{53}{6}[/tex] = [tex]\frac{2173}{18}[/tex]

Convert to mixed fraction:

120 [tex]\frac{13}{18}[/tex]

i just took the quiz

The required range of the function is 37.75 ≤ y ≤ 40. Option D is correct.

Raj’s bathtub is clogged and is draining at a rate of 1.5 gallons of water per minute. The table shows that the amount of water remaining in the bathtub, y, is a function of the time in minutes, x, that it has been draining.

x =   0      0.5      1       1.5  
y = 40    39.25   38    37.75    

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Since the range of the function is the value of Y, so the range according to the y column of the table is all real numbers such that 37.75 ≤ y ≤ 40

Thus, the required range of the function is 37.75 ≤ y ≤ 40. Option D is correct.

Answer: B

Step-by-step explanation:

A compound event is the combination of two or more events. Letter b explains how you roll a dice 4 times. The rest of the letters are only talking about one event. letter b shows more than 1. So the answer is B. In general the answer for compound events have to be a event that includes something done more than once

Answer:

x=30, A=132

Step-by-step explanation:

These 2 angels are alternate interior angles so they are equal

5x-18=3x+42

Solve.

2x=60

x=30

Now substitute x into angle A

A=150-18

A=132

Answer:

The variable X should be 30.

Step-by-step explanation:

∠132=5(30)-18° = ∠132=3(30)+42°

Answer:

saa.

Step-by-step explanation:

if you look at where the triangles connect, you will see they share an angle. that makes those two congruent. then yousee the SAA thrm. you go side (the line through one side) then the angle (the one that the two triangles share) then angle (the two marked congruent angles)
