square root of 625 is 25.
Step-by-step explanation:
Use the Pythagorean Theorem to find the hypotenuse.
a² + b² = c² where a and b are the sides and c is the hypotenuse
20² + 15² = c²
400 + 225 = c²
625 = c²
Write the fraction
2/7
as an equivalent fraction with the given denominator 28.
Answer:
8/28
Step-by-step explanation:
2/7 = ?/28
Well we have both of the denominators, and all they did was multiply the denominator of "7" by 4 to get "28" as the other denominator, so now all we have to do is multiply the first numerator by 4 to get the equivalent fraction.
2*4/7*4 = ?/28
8/28 = ?/28
The given numerator will be 8.
2/7 is equivalent to 8/28

Explain what you know about the product when you multiply tenths by tenths.
Answer:
1/10 times 1/10 is 1/100
Step-by-step explanation:
this is the same as 0.1
The product when you multiply tenths by tenths will become hundredths.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
For instance, since the challenge asks us to determine one-tenth of eight-tenths, 0.1 x 0.8 = 0.08 One tenth of eight-tenths equals eight hundredths because a tenth (or a tenth repeated by a tenth) is equal to a hundredth.
Repeated addition is what multiplication is. Put a 0 at the end of the number when combining whole numbers by 10.
The product when you multiply tenths by tenths will become hundredths.

A coffee shop owner blends a gourmet brand of coffee with a cheaper brand. The gourmet coffee usually sells for $9.00 per pound. The cheaper brand sells for $3.00 per pound. How much of each type should be mixed in order to have 40 pounds of coffee that is worth $7.50 per pound?
Answer:
30 pounds of $9 brand
10 pounds of $3 brand
Step-by-step explanation:
let x = $9 brand
let y = $3 brand
system of equations:
x + y = 40
9x + 3y = 40(7.5)
substitution method: x = 40 - y
9(40 - y) + 3y = 300
360 - 9y + 3y = 300
360 - 6y = 300
-6y = -60
y = 10
so, x = 40 - 10 or 30

Ben thinks of a number. If he doubles ut and add 4 he gets the same answer as multiplying the number by 10 and subtracting 8
Whag was Bens number
Answer:
Ben's number was [tex]\frac{3}{2}[/tex].
Step-by-step explanation:
Given that:
Ben thinks of a number.
Let,
x be that number.
According to given statement;
Double of number plus 4 is equals to number multiplied by 10 and subtracting 8.
2x + 4 = (x*10) - 8
2x + 4 = 10x - 8
4 + 8 = 10x - 2x
12 = 8x
8x = 12
Dividing both sides by 8
[tex]\frac{8x}{8}=\frac{12}{8}\\x=\frac{3}{2}[/tex]
Hence,
Ben's number was [tex]\frac{3}{2}[/tex].
