find the radius of a sphere with surface area of 100 Pi square centimeters

Answers

Answer 1

The surface area of a sphere = 4πr²

4πr²=100π

Dividing both sides by 4π,

r² = 100π÷4π = 25

r² = 25

Taking the square root on both sides,

r = 5 centimeters

The table shows the results of spinning a spinner several times. (Don’t mind my answer)

Answers

The answer is 1/4. To find this, add all the frequencies together, then you get 12. Then add B and C together to get 4. Divide 12 by 4 and get 1/4.

The experimental probability of spinning a B or a C is [tex]$ \frac{1}{4} $[/tex].

To find the experimental probability of spinning a B or a C, we need to sum up the frequencies of outcomes B and C and then divide that by the total number of spins.

Given frequencies:

Outcome A: 3

Outcome B: 2

Outcome C: 1

Outcome D: 4

Outcome E: 2

Total frequency of B and C: 2 (from outcome B) + 1 (from outcome C) = 3

Total number of spins: Sum of all frequencies = 3 + 2 + 1 + 4 + 2 = 12

Experimental probability of spinning a B or a C: [tex]$\frac{\text{Total frequency of B and C}}{\text{Total number of spins}} = \frac{3}{12} = \frac{1}{4}$[/tex]

So, the experimental probability of spinning a B or a C is [tex]$\frac{1}{4}$[/tex].

The internal angle of a square is equal to [tex]90\°[/tex]

To find the internal angle of a regular pentagon, apply the formula

When Sally went bowling her scores were 108, 72, and 95. If she bowls a 4th game, what will her score need to be to give her an average of 91?

Answers

x= score of 4th game

Add the 4 scores, divide by 4 and set it equal to 91

(108 + 72 + 95 + x)/ 4= 91
multiply both sides by 4 to eliminate fraction

108 + 72 + 95 + x= 364
275 + x= 364

subtract both sides by 275
x= 89

ANSWER: The scored needed for the fourth game is 89.

Hope this helps! :)

To achieve an average score of 91, Sally needs to bowl an 89 in her fourth game, calculated by subtracting her current total score of 275 from the desired total of 364 points.

To calculate the score Sally needs in her fourth game to achieve an average of 91, we first need to determine the total points she needs after four games. We can calculate the required total points by multiplying the desired average score by the number of games:

91 × 4 = 364 total points

Next, we add up the scores from Sally's first three games:

108 + 72 + 95 = 275 points

Finally, we subtract the sum of her first three games from the total required points to find the score Sally needs in her fourth game:

364 - 275 = 89 points

Therefore, Sally needs to bowl a score of 89 in her fourth game to achieve an average of 91.

Justin is exchanging dollars for rolls of quarters and rolls of dimes at a bank. Each roll of quarters has a value of $10 and each roll of dimes has a value of $5. He exchanges $90 and receives 11 rolls of coins. How many of each type of roll of coins did he receive?

Answers

Well, it really depends but it could be 9 rolls of quarters, 5 rolls of quarters and 8 rolls of dimes, 4 rolls of quarters and 10 rolls of dimes, 3 rolls of quarters and 12 rolls of dimes, etc.

Answer:

Justin got 7 rolls of quarters and 4 rolls of dimes.

Step-by-step explanation:

Let the roll of quarters be x

Let the rolls of dimes be y

As total money received is $90, the equation becomes;

[tex]10x+5y=90[/tex] .....(1)

And he got 11 roll of coins, so equation becomes;

[tex]x+y=11[/tex] or [tex]x=11-y[/tex] .... (2)

Substituting the value of x from (2) in (1)

[tex]10(11-y)+5y=90[/tex]

[tex]=> 110-10y+5y=90[/tex]

[tex]=> -5y=-110+90[/tex]

[tex]=> -5y=-20[/tex]

So, y = 4

As [tex]x=11-y[/tex]

So, [tex]x=11-4[/tex]

x = 7

Hence, Justin got 7 rolls of quarters and 4 rolls of dimes.

Which system of equation can represent the equation?

Answers

Answer:

y₁ = --------------
          log(4)

         log(2 + x)
y₂ = ----------------
           log(2)

Explanation:

1) Here you must use the property named change of base of the logarithm.

That rule is:

[tex]log_{a}b= \frac{log_c{b}}{log_ca} [/tex]

2) Changing to base 10 that is:

[tex]log_{b}a= \frac{loga}{logb} [/tex]

3) Using it with the given equation, you get:

[tex]log_4(x+3)= \frac{log_(x+3)}{log(4)} log_2(2+x)= \frac{log(2+x)}{log(2)}[/tex]

4) Now, to set your system you can make the left side of the equation equal to y₁ and the right side equal to y₂

       log(x+3)
y₁ = -------------
       log(4)

         log(2 + x)
y₂ = ---------------
            log(2)

And that is your system which is the first choice of the list.

1 lb of walnut= 2 lb

3*3=9

A new patio will be an irregular hexagon. The patio will have two long parallel sides and an area of 360 square feet. The area of a geometrically similar patio is 250 square feet, and it’s long parallel sides are 12.5 feet apart. What is the corresponding distance on the new patio

Answers

The length of the new patio will be evaluated as follows:
The area scale factor=(area of new patio)/(area of original patio)
=360/250
=36/25
but
Linear scale factor=√(area scale factor)
Linear scale factor=√(36/25)=6/5
thus the length of the patio will be:
length=(linear scale factor)*(length of the original patio)
=6/5×12.5=15 ft

Which word best describes 8(2x +4)

Answers

Final answer:

The word that best describes 8(2x + 4) is multiplication. When we multiply a number by an expression, we distribute the multiplication to each term in the expression. Simplifying further, 8(2x + 4) becomes 16x + 32.

Explanation:

The word that best describes 8(2x + 4) is multiplication. In this expression, the number 8 is being multiplied by the expression 2x + 4. When we multiply a number by an expression, we distribute the multiplication to each term in the expression. Therefore, the expression becomes 8 * 2x + 8 * 4.

Simplifying further, we get 16x + 32. So, the word that best describes 8(2x + 4) is multiplication.

Answers

The first step for solving this expression is to remove the first set of parenthesis.
-x² + 9 + (-3x² - 11x + 4)
Now,, remember that when there is a "+"sign in front of the parenthesis,, then the parenthesis in the expression remains the same. This means that all you need to do for the second side of the expression is remove the parenthesis.
-x² + 9 + -3x² - 11x + 4
Collect the like terms that have an exponent of two.
-4x² + 9 - 11x + 4
Add the regular numbers together.
-4x² + 13 - 11x
Lastly,, use the commutative property to reorder the terms and get your final answer.
-4x² - 11x + 13
Since we cannot simplify this expression down any further,, our final answer is going to be -4x² - 11x + 13 or option B.
Let me know if you have any further questions.
