The cube volume is 1000cm find the all face area
A. 200cm
B. 300cm
C. 500cm
D. 600cm
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)
Darnell is trying to understand the Pythagorean Theorem by drawing a few triangles. He found that 1² + 1² = (√2)² is accurate. Which statement is true about Darnell’s triangle?
A. The triangle is not a right triangle because the lengths of its sides measure the same.
B. The triangle is not a right triangle because the hypotenuse is shorter that the lengths of its sides.
C. The triangle is a right triangle, the lengths of its sides are 1 and √2 with a hypotenuse of 1.
D. The triangle is a right triangle, the lengths of its sides are 1 and 1 with a hypotenuse of √2.
PLEASE HELP ASAP!!!!
Answer:
D. The triangle is a right triangle, the lengths of its sides are 1 and 1 with a hypotenuse of √2.
Step-by-step explanation:
The Pythagorean Theorem is modeled by a² + b² = c².
c represents the hypotenuse and a and b represent the other two sides.
The Pythagorean Theorem can only be applied to right triangles.
Answer:
D.
Step-by-step explanation:
Srry if your question was already answered but im very sure its D.

Mr. Jimenez bought 12 gallons of gasoline at a station in Fayetteville. The
gas costs $1.59 cents per gallon. About how much did he pay for the gas?
A $10
B $15
C $20
D $25
please help and show work please
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!
Describe how you could use algebra tiles to model the equation 5x = 30
Answer:
If I’m interpreting this correctly: If there are 25 tiles in groups of 5, how many groups would it take to have 25 total tiles...5 groups of 5 tiles would equal a total of 25 tiles altogether.

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?
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.

Step-by-step explanation:
70% of x is 63. Write an equation that represents this statement.
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
good luck :)
i hope this helps

Find 44% of 625 using the facts that 40% of 625 is 250 and 4% of 625 is 25.
Answer:
275
Step-by-step explanation:
40% + 4%
250 + 25 = 275
OR
625 x .44 = 275
Answer:
= 275
Step-by-step explanation:
40% of 625 = 625 x 0.40 = 250
625 x 0.04 = 25
so 625 x 0.44 = 275

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)
