A party supply store needs to know how much helium to put inside of balloons. Determine the volume of a spherically shaped balloon with a radius of 10.5 cm.

Answer:

- 25/13

Step-by-step explanation:

4+9x+26= -4x+5

30+9x= -4+5

9x+4x= 5-30

13x= -25

x=-25/13

Answer:

Step-by-step explanation:

g(x) = (x+4)² - 5

Answer:

x=4

Step-by-step explanation:

1. 2x+4=12

2. 2x+4-4=12-4

3. 2x=8

4. 2x/2=8/2

5. x=4

Answer:

x=4

Step-by-step explanation:

2x+4=12

Step 1: subtract both sides by 4

4-4=0 and 12-4=8

Now you are left with 2x=8

Step 2: divide 2 on both sides

2/2=1x and 8/2=4

Therefore, x=4

Answer: 40

Step-by-step explanation:

Given

Jar contains 200 old dimes

Chances to pick the 1960s is 20% i.e. 1960s is 20% of 200 old dimes

So, we can write

[tex]\Rightarrow \text{No of 1960s is }=20\%\ \text{of}\ 200=0.2\times 200\\\Rightarrow \text{No of 1960s is }=40[/tex]

Answer:

b

Step-by-step explanation:

Answer: Step 1: Find the whole number

We first want to find the whole number, and to do this we divide the numerator by the denominator. Since we are only interested in whole numbers, we ignore any numbers to the right of the decimal point.

50/10 = 5

Now that we have our whole number for the mixed fraction, we need to find our new numerator for the fraction part of the mixed number.

Step 2: Get the new numerator

To work this out we'll use the whole number we calculated in step one (5) and multiply it by the original denominator (10). The result of that multiplication is then subtracted from the original numerator:

50 - (10 x 5) = 0

Step 3: Our mixed fraction

We've now simplified 50/10 to a mixed number. To see it, we just need to put the whole number together with our new numerator and original denominator:

5

0

10

You maybe have noticed here that our new numerator is actually 0. Since there is no remainder, we can remove the entire fraction part of this mixed number, leaving us with a final answer of:

5

Answer:1

Step-by-step explanation:

Answer:

Step-by-step explanation:

x      - an angle

x - 150°     - the angle's suplementary angle

Measure of suplementery angles adds to 180°

x + x - 150° = 180°

2x = 180° + 150°

2x = 330°

 x = 330°÷2

 x = 165°

x-150° = 165° = 150° = 15°

Answer:

D. (3,-2)

Step-by-step explanation:

When we rotate a point 180 degrees about the origin, the rule is:

(x,y) -> (-x,-y)

So let's use this rule with our point.

(-3,2) -> (3,-2)

The answer is D (3,-2)

Answer:

is 2 because you multiply 7×6 and then you divide 21 by 42 because 7×6 is 42 so you do 42÷21 and you get 2 as your answer I hope this helps

Answer:

8/25 or 32%

Step-by-step explanation:

if 17/25 do sprout on time than 8 or the twenty five don't.  So 8/25 is the amount that don't and by multiplying both the top and bottom fraction by 4 you will get 32/100 or 32%
