The answer is b. In b, 10 is divided from both 90 and 60, and that's gives you 9+6.

You're answer is a. 30(3 + 2)

Distribute the 30 back into the parenthesis.

30(3) = 90
30(2) = 60

90 + 60 (which is the original question).

Therefore, A is your best choice

hope this helps

Solve for x: 2/7x-1/7x=100

Jet001 [13]

2/7x-1/7x=100
subtract the 2/7x and the 1/7x
so it would be
1/7x=100
multiply 1/7 on both sides
so
x=100 times 1/7
solve
x=100/7
x=14 2/7

A or B? Please show work!

Vilka [71]

Answer:

Step-by-step explanation:

x/4=3/8 multiply both sides by 4

x=12/8 divide numerator and denominator by 4

x=3/2

x=1.5

x/8=1.5/2 multiply both sides by 8

x=12/2

x=6

Find the volume of the cone. Use 3.14 for π. Round to the nearest tenth.

Leviafan [203]

$Volume\,\,of\,\,cone=1527.1\,\,cm^3$

So, Option C is correct.

Step-by-step explanation:

We need to find Volume of cone.

We are given:

π = 3.14

Length = 27 cm

Diameter = 15 cm

The formula used to find Volume of cone is:

$Volume\,\,of\,\,cone=\frac{1}{3}\pi r^2h$

We are given diameter but we need radius in the formula

So, Radius = Diameter/2 = 15/2 = 7.5 cm

We need to find height of cone.

Using Pythagoras theorem:

$h^2=p^2+b^2\\ (27)^2=p^2+(7.5)^2\\729=p^2+56.25\\p^2=729-56.25\\p^2=672.75\\Taking\,\,square\,\,root:\\p=25.93$

So, Height of cone = p= 25.93

So, r= 7.5 and h= 25.93 and π = 3.14

Putting values in the formula:

$Volume\,\,of\,\,cone=\frac{1}{3}3.14*(7.5)^2*25.93$

$Volume\,\,of\,\,cone=1526.62$

Rounding off to the nearest tenth:

$Volume\,\,of\,\,cone=1527.1\,\,cm^3$

So, Option C is correct.

List three solutions for the inequality x ≤ 3 and give three<br> numbers that are not solutions.

rjkz [21]

Answer:

Not:

1921131

Step-by-step explanation:

x needs to be equal or less than 3. It doesn't say that x cannot be negative so any number 3 and below is fine.

Not solutions would be any number above 3 in value
