A cube has a surface are of 54. What's the volume?
A. 36
B. 27
C. 18
D. 64
80 points!!
We know that,
[tex]\bigstar \: \boxed{\sf {Volume_{(Cube)} = (\ell)^3}} \\ [/tex]
l = length of sideLet's find out the side first. We know that,
[tex]\bigstar \: \boxed{\sf {T.S.A_{(Cube)} = 6\ell^2}} \\ [/tex]
According to the question,
[tex] \longmapsto \sf {54 = 6\ell^2 } [/tex]
[tex] \longmapsto \sf {\dfrac{54}{6} = \ell^2 } [/tex]
[tex] \longmapsto \sf {9 = \ell^2 } [/tex]
[tex] \longmapsto \sf {\sqrt{9} = \ell } [/tex]
[tex] \longmapsto \sf \red{3 \: units = \ell } [/tex]
Now, calculating volume :
[tex]\bigstar \: \boxed{\sf {Volume_{(Cube)} = (\ell)^3}} \\ [/tex]
→ Volume = l × l × l
→ Volume = 3 × 3 × 3
→ Volume = 27
Option B is correct.Determine the measures of the angles if they are both vertical and supplementary.
Answer:
90, 90
Step-by-step explanation:
Since the two angles are vertical, it means that they must have the same measure. Because they are supplementary, that means they add to 180. Thus, the two angles must be 90 and 90.

For soccer season, Fred decided to buy a ball for $6.30, new shorts for $18.50, as well as a pair of soccer shoes for $43.20. Fred currently has $24.60, and a coupon for $14.00 off his purchase. How much more money does Fred need to complete his purchase.
Answer:
$29.40
Step-by-step explanation:
Ball: $6.30
new shorts: $18.50
soccer shoes: $43.20
total: $68
Fred has $24.60
Total - freds money
68-24.60= 43.40 (amount Fred needs to pay without coupon)
With coupon:
43.40-14= 29.40

5(2 + x) apply distributive property
Answer:
10+5x
Step-by-step explanation:
The distributive property is where you multiply what's on the outside with ALL the terms on the inside.
Here, you have to multiply 5 by two terms on the inside: 2 and x. 5*2 is 10 and 5*x is 5x. Add them together and your answer is 10+5x (or, 5x+10).

Question 5
show the work please
Answer:
D) 27
Step-by-step explanation:
It's a rectangle so the opposite sides are congruent to each other.
Long Side:
6x + 6 = 42
subtract 6 from both sides:
6x = 36
divide both sides by 6:
x = 6
Short Side:
5y + 5 = 30
subtract 5 from both sides:
5y = 25
divide both sides by 5:
y = 5
The Equation:
2x + 3y
substitute in the values:
2(6) + 3(5)
do the multiplication:
12 + 15
add the values together:
27
ill give brainlyest to anyone who can help
Answer:
Step-by-step explanation:
Substitution method:
y= -2x + 2
x - 2y = 6
so y = (-2x + 2)
Substitute into y
Hence x - 2y = 6 is:
x + 2x +2 = 6 (+2x because there was - in the equations so -×- = +)
3x + 2=6
Then bring 2 to the other side so
3x = 6-2
3x = 4
x = 3/4 or 0.75
To find y :
y= (-2 × 3/4) + 2
y = -1.5 +2
y = 0.5
That's all I can do for now!
Please answer this. Find the angles
Answer:
m2 = 145
m3 = 145
m4 = 35
Step-by-step explanation:
m<1 = m<4 because of vertical angles
m<2 + m<1 = 180
m<2 + 35 = 180
m<2 = 145
m<2 = m<3 because of vertical angles
Answer:
35°145°145°35°Step-by-step explanation:
180°-35°=145°
vertical angles are congruent so 1 ≅4 and 2≅3
