Answer: Density = 0.23 tons per cubic meter.

Step-by-step explanation:

Formula : Density=\dfrac{Mass(in \ ton)}{Volume (in\ m^3)}

1 ton = 32000 ounces

⇒ 1 ounce = 0.00003125 ton

⇒  7 ounces = 7(0.00003125)=  0.00021875 ton

1 gallon = 0.00378541 cubic meter

2.5 gallons = 0.009475 cubic meter

Density= \dfrac{0.00021875}{0.009475}\text{ tons per cubic meter}

\dfrac{21875}{94750}\text{ tons per cubic meter}\approx0.23\text{ tons per cubic meter}

Hence, Density = 0.23 tons per cubic meter.

What are the factors of m^2 – 12m + 20?
Anika [276]
I don't know what you mean by factors, but the quadratic equation of m^2 - 12m + 20 can be simplified to (m - 10)(m - 2).

Hope this helps!

Sketch the areas under the standard normal curve over
SOVA2 [1]

Answer:

a) P(Z

b) P(Z>0.15)=1-0.560=0.440

c) P(-1.40

Step-by-step explanation:

a)To the left of z = 0.72.

For this case the shaded area is on the figure 1 attached.

And we can find the area with the normal standard table of with the following excel code:

=NORM.DIST(0.72,0,1,TRUE)

P(Z

b)To the right of z = 0.15.

For this case the shaded area is on the figure 2 attached.

And we can find the area with the normal standard table of with the following excel code:

=1-NORM.DIST(0.15,0,1,TRUE)

P(Z>0.15)=1-0.560=0.440

c)Between z = -1.40 and z = 2.03.

For this case the shaded area is on the figure 3 attached.

And we can find the area with the normal standard table of with the following excel code:

=NORM.DIST(2.03,0,1,TRUE)-NORM.DIST(-1.40,0,1,TRUE)

P(-1.40

Every week, Fred deposits $84 into his savings account, which is 20% of his weekly income. How much income does Fred make each w
Alexeev081 [22]

Answer:

Fred's monthly income is $420.

Step-by-step explanation:

There are two main ways of solving this. There are many ways of solving for this, but personally I like to do divide the percentage by 100 so it would look something like this-

100/20 = 5.

Then I multiply $84 by 5 which is $420.

Find the value of x.
Korvikt [17]

Answer:

x = 52

Step-by-step explanation:

Since the inscribed angle measures 64 degrees, the minor arc is 64*2 = 128 degrees. Therefore the major arc is 180-128 = 232 degrees. Angle X is the difference of major and minor arc divided by 2, so X = (232-128)/2 = 52 degrees.
