Answer:
1st: 22, 2nd: 27, 3rd: 88
Step-by-step explanation:
Make an equation
If she recieved x calls the 1st evening, then the 2nd evening she recieved x+5, and the 3rd evening she recieved 4x.
x+x+5+4x=137
Combine like terms
6x+5=137
Subtract 5 from both sides
6x=132
Divide by 6 on both sides
x=22
First:
22 calls
Second:
x+5
22+5
27 calls
Third:
4x
4*22
88 calls
Hope this helps!
Answer:
The radius of the cylinder is 2.52 cm.
Step-by-step explanation:
The formula for the volume of a cylinder of radius r and height h is
V = πr²h. We can solve this for r² by dividing both sides of the equation by πh:
r² = V / (πh)
Then the desired radius is found by taking the square root of this.
r = √{V / [πh]}
200 cm^2
Here, r² = ------------------- = 6.37 cm^2
3.14(10 cm)
and so r = √6.37 cm^2 = 2.52 cm
The radius of the cylinder is 2.52 cm.
Answer:
The people who said Yes to having a pet in their home is greater
Step-by-step explanation:
We are asked to compare 18% and 14/25. Let's get them to their lowest common denominator:
18% = 18/100
14/25 * 4 = 56/100
18/100 is clearly much less than 56/100. If you don't want to write all this out, you can also eyeball that 14/25 is over half, whereas 18% is not close to half.
I hope this helps! Sorry if its doesn't though:( I hope you have a amazing day! And maybe you could mark this brainly?
The exponent of the power in the scientific notation of the result of the expression (9.1 × 10^9)(7.5 × 10^2) is 12
<h3>How does scientific notations work?</h3>
The number is written in the form 
where we have 
The number b shows the order, which is the most important figure for which scientific notation is used. It tells us how much order large or small a value is in powers of 10. We can for a time, ignore the value of 'a' for two comparable quantities and only compare their orders(this type of comparison is useful when difference is too big, like size of human to size of a star etc sort of comparisons).
Scientific notations have some of the profits as:
- Better readability due to compact representation
- Its value in terms of power of 10 is known, which helps in easy comparison of quantities differing by a large value.
Expressing the multiplication of (9.1 × 10^9)(7.5 × 10^2) in terms of scientific notation, we get:
(the exponent is 12)
Thus, the exponent of the power in the scientific notation of the result of the expression (9.1 × 10^9)(7.5 × 10^2) is 12
