Answer:
C. The factors had the same sign.
Step-by-step explanation:
Factors that had the same sign will have a positive product.
Two positive numbers will have a positive product.
For example, 3 times 3 is 9.
Two negative numbers will also have a positive product, because multiplying negative numbers by other negative numbers will cancel out the negative.
For example, -3 times -3 is 9.
So, C is correct
Answer:
0.8 would be the approximate height
Step-by-step explanation:
you can make an equation and solve for the height (x)
375 = 3.14(12.5^2)x
when you solve this equation, you specifically get 0.76. but your question is asking for the approximate, so you would round it up to 0.8. hope this helps!
A fraction that means the same as 2/3 is 4/6.
To find this, you can simply multiple both the numerator and denominator (top and bottom) by any number as long as it's the same number for both top and bottom.
In this case, we used 2 as the number, and multipled it to the top and bottom of 2/3, to get 4/6.
I hope this helps!

Answer:
25.19
Step-by-step explanation:
Change the percentage into a decimal. 30% is the same as saying 30/100.
This is 30 hundredths and in decimal form, it looks like this:
0.30 since 30/100 is the same as 3/10
To find out how much of a discount he gets, multiply 0.30 times 35.99.
0.30 x 35.99 = 10.797 which rounds up to 10.80.
This means he gets 10.80 off of the original price.
To find out what the new price is, subtract that from the original price.
35.99 - 10.80 = 25.19
