Answer:
C: √74
Step-by-step explanation:
We have to use the Pythagorean theorem to answer this (a² + b² + c²). We have a and b so all we have to do is square 5 and 7 (a and b) so we get a² b², then we add this to get c² as stated by the Pythagorean theorem. So, 7² (7 x 7) is 49, and 5² (5 x 5) is 25. 25+49 (a² + b²) is 74 (c²). So the square root of this would be the absolute length of the hypotenuse because this is the hypotenuse squared. Meaning that the answer would be √74 (square root of 74)

Answer:
see below
Step-by-step explanation:
a. -11r ≥ 220
Divide both sides by -11 to isolate r.
r ≥ -20
b.
-8 ≤ -7 + (x/10)
Add 7 to both sides.
-1 ≤ x/10
Multiply both sides by 10 to cancel out the denominator of x.
-10 ≤ x
c. -1 - 6(5q - 2) ≥ -139
Distribute the -6 across the parentheses.
-1 - 30q + 12 ≥ -139
Combine like terms on the left side.
-30q + 11 ≥ -139
Subtract 11 from both sides.
-30q ≥ -150
Divide both sides by -30 to isolate q.
q ≥ 5
Hope this helps!
divide both sides by -11
since both sides are divided, flip the sign
r<=-20
r is less than or equal to negative twenty

Explain how to solve an equation in the form x². Then, explain how to solve an equation in the form √=x.
Answers
Answer:
To solve an equation in the form of x^2, you square root both sides of the equation, since x^2 equal x^x, the square root of x^2 is x
To solve an equation in the from of √=x, you square both sides of the equation, the square root of x's square is x, √x^2 = x.

The cube volume is 1000cm find the all face area
A. 200cm
B. 300cm
C. 500cm
D. 600cm
Answers
Answer:
D. 600 [tex]cm^{2}[/tex]
Step-by-step explanation:
Volume of a cube = [tex]s^{3}[/tex] = 1000, s = [tex]\sqrt[3]{1000} =10[/tex]
So, the side length is 10 cm
Surface area of a cube is 6[tex]s^{2}[/tex] where s is the side length
so [tex]s^{2}[/tex] = [tex]10cm^{2} = 100 cm^2[/tex]
6*100[tex]cm^{2}[/tex] = 600 [tex]cm^{2}[/tex]
So the answer is D. 600 cm (it should have a little superscript 2 next to it)
70% of x is 63. Write an equation that represents this statement.
Answers
answer:
70/100x = 63
step-by-step explanation:
so first we must turn 70% into a fraction-
70/100
and since we know that 63 is the answer
that must mean that x is being multiplied by 70/100
therefore making the equation 70/100x=63

Taylor emptied out her change jar to buy a new soccer ball for practice. The jar contained 128 coins consisting of quarters and dimes that totaled $25.10. Which system of equations could be used to determine how many quarters, q, and how many dimes, d, Taylor had in her change jar?
Answers
Answer:
.25q+.10d=25.10
q+d=128
Step-by-step explanation:
Since a quarter is 25 cents and a dime is 10 cents that is how you figure out your first equation. You set it equal to 25.10 because that is the amount of money it totals to. The second equation (q+d=128) is used because the amount of quarters plus dimes needs to make 128.
q+d=128
25q+10d=2510
These are the system of equations. To solve it, we do this:
q=128-d
25(128-d)+10d=2510
3200-25d+10d=2510
15d=690
d=46
q=128-46=82
