2/5 of the product of 5/6 and 42
no links plz and explain
10 pts
Answer:
140
Step-by-step explanation:
first you take the product of 5/6 and 42/1, which is 210/6.
Then you devide that with 5, 210/6/5 = 210/30 or 210/6 . 1/5 = 70.
Next you multiply that with 2; 70 . 2 = 140.

A tennis ball has a radius of about 1.4 inches What is the volume of the tennis ball to the nearest half inch.? Use 3.14 as an approximation for
Answer:
Volume of tennis ball = 11.49 inch³
Step-by-step explanation:
Given:
Radius of tennis ball = 1.4 inches
Value of π = 3.14
Find:
Volume of tennis ball
Computation:
Volume of sphere = [4/3][π][r]³
Volume of tennis ball = [4/3][π][Radius of tennis ball]³
Volume of tennis ball = [4/3][3.14][1.4]³
Volume of tennis ball = [1.333][3.14][1.4]³
Volume of tennis ball = [1.333][3.14][2.744]
Volume of tennis ball = [4.1856][2.744]
Volume of tennis ball = 11.4852
Volume of tennis ball = 11.49 inch³

the diameter of a circle is 4 in. find its area in terms of pi
Step-by-step explanation:
A ≈12.57in²
d = Diameter
Using the formulas
A=πr2
d=2r
Solving forA
A=1/4πd²=1/4·π·4²≈12.56637in²
Answer:
A = 4π in²
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( r is the radius )
Here d = 4, then r = 4 ÷ 2 = 2
A = π × 2² = 4π in²

If 3^r=19, then 3^(r+1)=3^r × 3=19 × 3=57
This question has four parts.
32 Colton is heating a pot of water. He records the temperature of the water in
the pot every minute. This equation models Colton's data, where x represents
the number of minutes the water has been heated, and y represents the
temperature of the water in degrees Fahrenheit.
y = 7.5x + 40
What is the temperature in degrees Fahrenheit of colton's pot of water after 16 minutes. Hi Ayer boils at a temperature of 212 after 16 minutes of heating how much additional time to the nearest minute will be needed for the water to boil.
Answer:
Step-by-step explanation:
PART A
7.5 represents the ounces of water heating up inside the pot.
PART B
40 in the equation will represent the starting point. It can be described as where the temperature started.
PART C
The temperature, of Colton's pot of water after 16 minutes will be 120° 7.5(16) = 120 7.5 being the ounces of water and 16 being minutes.
PART D
After 16 minutes of heating, about 13.3 as additional time will be added for the water to start boiling at 212°.
The temperature in degrees Fahrenheit of colton's pot of water after 16 minutes is 160° F. The additional time to the nearest minute will be needed for the water to boil is 7 minutes approximately.
How to evaluate a given mathematical expression with variables if values of the variables are known?You can simply replace those variables with the value you know of them and then operate on those values to get a final value. This is the result of that expression at those values of the considered variables.
For this case, it is specified that:
y = 7.5x + 40 ( where x = number of minutes the number of minutes the water has been heated, and y represents the temperature of the water in degrees Fahrenheit.)So, if the water is boiling for x = 16 minutes, then the temperature would be:
[tex]y = 7.5 \times 16 +40 = 160^\circ \: \rm F[/tex]
Also, we need to make the temperature reach to 212 degree Fahrenheit after 16 minute of boiling.
Let it takes T time (in minutes more) to reach 212 degree Fahrenheit, then: y = 212, x = 16 + T
Putting these values in the equation, we get:
[tex]y = 7.5x + 40\\212=7.5\times(16+T) + 40\\212 = 120 + 7.5T + 40\\7.5T = 212-160\\\\T = \dfrac{212-160}{7.5} = \dfrac{52}{7.5} \approx 6.93 \: \rm minutes \approx 7 \: \rm minutes[/tex]
Thus, the temperature in degrees Fahrenheit of colton's pot of water after 16 minutes is 160° F. The additional time to the nearest minute will be needed for the water to boil is 7 minutes approximately.

how do I solve for something like this and figure out what x equals?
Answer:
There are many way to solve this problem. But I'm using one X = 5 and X = 8.
Step-by-step explanation:
5 x 10 = 50
50 + 2 = 52
52 + 12 = 64
Heads up
4 + 8 = 12
Answer:
x=8
Step-by-step explanation:
first you have to multiply 2 and x and then 2 and 4. You should get 2x + 8. then you should add comon numwrals which would be 5x and 2x to get 7x. your equation should now be 7x + 8= 64. then subtract 8 from 64 to get 56. it should now be 7x = 56. devide 56 by 7 and 7x by 7. your answer is x=8

Tareq is 7 years old and his older sister Fatma is 10. Tareq challenges his sister to a pizza eating contest. They each make an identical extra extra large pizza. Tareq eats 2/8 of his pizza. His sister Fatma eats 3/4 of her pizza. Who ate more pizza and how do you know?
Answer:
Fatima ate more pizza
Step-by-step explanation:
Assume
The total pizza = 1
Tareq eats 2/8 of his pizza
Tareeq = 2/8 of 1
= 2/8 * 1
= 2/8
= 0.25 of his pizza
Fatma eats 3/4 of her pizza
Fatima = 3/4 of 1
= 3/4 * 1
= 3/4
= 0.75 of her pizza
The pizza is identical in size
Therefore,
Fatima ate more pizza
I got to know this by finding the decimal of fraction eaten and picking the larger decimal value as who ate more pizza
