The total area of a cube is 486 cm2.
Find the area of one face and its lateral area.
Answer:
Step-by-step explanation:
A cube has 6 faces so:
Area of 1 face = 486/6 = 81 cm^2.
Lateral area = 4 * face area
= 4 * 81
= 324 cm2.
Answer:
one face = 81 cm²
lateral area = 324 cm²
Step-by-step explanation:
486/6 = 81 cm²
81 x 4 = 324 cm²

A driving range charges $4 to rent a golf club plus $2.75 for every bucket of golf balls you hit. Write an equation that shows the total cost c of hitting b buckets of golf balls.
Answer:
2.75x+4
Step-by-step explanation:
2.75x because for every one bucket it cost 2.75 dollars and I wouldn’t put x next to 4 since you only have to pay one time.

Answer:
She made $1230 more on printed shirts than plain shirts in 25 weeks.
Step-by-step explanation:
Hi,
Okay, I have to admit, this is pretty complicated. But, it's not impossible :) First things first, we know that the equation in the table is the number of shirts sold after W number of weeks. We know that we need to, first, find the total number of shirts sold in 25 weeks.
The equation for the plain shirts is 5w -4. Let's start with that.
Plugin 25 for w to find the total number of plain shirts sold after 25 weeks.
5w - 4
5(25) - 4
= 121
She sold 121 plain shirts after 25 weeks. But we're not done yet, we still have to see how much money she made after selling 121 plain shirts. To do this, we have to multiply the total number of plains shirts sold by 15. (we know that each plain short costs $15, that's why we're multiplying it by 121)
When you do this...
121 x 15
You get...
$1815
She got $1815 after 25 weeks just for selling plain shirts.
Now, let's find the total cost of printed shirts after 25 weeks.
The equation for the printed shirts if 8w + 3.
8w + 3
8(25) + 3
= 203
She sold 203 printed shirts in 25 weeks. Let's find the cost. Each printed shirt costs $15 so we need to multiply 203 by 15.
203 x 15
You get...
$3045
She made $3045 by selling printed shirts in 25 weeks.
Now, we have to subtract $3045 by $1815 to find how much more she made. You get...
3045 - 1815
= $1230
She made $1230 more on printed shirts than plain shirts in 25 weeks.
I really hope this helps :)
A B C ~ A D E: find x
Answer:
[tex] \frac{20}{28} = \frac{15}{2x + 3} \\ 20(2x + 3) = 15 \times 28 \\ 40x + 60 = 420 \\ 40x = 420 - 60\\ 40x = 360 \\ x = 9[/tex]
The value of x using the proportionality rule is 9.
What are Similar Triangles?Two triangles are said to be similar if the triangles are of the same shape but different size. The angles of the triangle will be equal and the sides are proportional.
Given that the two triangles ABC and ADE are similar triangles.
We have to find the value of x.
If two triangles are similar, then the corresponding sides are proportional.
A corresponds to A, B corresponds to D and C corresponds to E.
AB / AD = BC / DE = AC / AD.
Consider AB / AD = BC / DE.
28 / 20 = 2x+3 / 15
Cross multiplying,
20 (2x + 3) = 28 × 15
2x + 3 = 21
2x = 18
x = 9
Hence the value of x is 9.

23B) The equation is 24-x(7)=10
Because she spends twenty four dollars on seven rings which we don't know how much it costs giving us a change of ten dollars
23C) The equations solution:
24-x(7)=10
24-x*7=10
-7x=10-24
-7x=-14
-7x/-7=-14/-7
x=2
23D) Twenty four dollars is spent on seven rings that costs two dollars each, giving a total of fourteen dollars spendings. Therefore the change is ten dollars.

ΔABC and HGF are similar.
Step-by-step explanation:
In the given triangles ABC and HGF,
If both the triangles are similar,
Their corresponding sides will be proportional.
[tex]\frac{AB}{GH}=\frac{BC}{FG}= \frac{AB}{HF}[/tex]
[tex]\frac{72}{12}=\frac{48}{8}= \frac{84}{14}[/tex]
6 = 6 = 6
True.
Therefore, ΔABC and HGF are similar.
Solve w+ 13 = 11w - 7. w =
Answer:
5w+13
Step-by-step explanation:
w+13=11w-7w
=w+13+11w+-7w
=(w+11w+-7w)+(13)
=5w+13
Answer:
w=2
Step-by-step explanation:
Let's solve your equation step-by-step.
w+13=11w−7
Step 1: Subtract 11w from both sides.
w+13−11w=11w−7−11w
−10w+13=−7
Step 2: Subtract 13 from both sides.
−10w+13−13=−7−13
−10w=−20
Step 3: Divide both sides by -10.
−10w/−10 =−20/−10
Answer:
w=2

what is x 1/4(8x+12)=21
Answer:
x = 9
Step-by-step explanation:
1/4(8x+12) =21
1/4 * 8x = 2x
1/4 * 12 = 3
2x + 3 = 21
21 - 3 = 18
2x = 18
18/2 = 9
x = 9
Answer:
x=9
Step-by-step explanation:
Try first by multiplying the 8x and 12 in the brackets by 1/4 so it will be:2x+3=21
Now subtract 3 from each side2x=18
Then divide each side by 2x=9
Find a point K on the segment with endpoints F(-8, 10) and G(8, -2) that
partitions the segment, starting at point F 3/4 of the way to point G
Given:
The endpoints of a line segment are F(-8, 10) and G(8, -2).
Point K partitions the segment, starting at point F [tex]\dfrac{3}{4}[/tex] of the way to point G.
To find:
The coordinates of point K.
Solution:
Section formula: If a point divides a line segment in m:n, then the coordinates of that point are
[tex]Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)[/tex]
According to the given information,
[tex]\dfrac{FK}{FG}=\dfrac{3}{4}[/tex]
[tex]FK:FG=3:4[/tex]
Now,
[tex]FK:KG=FK:(FG-FK)[/tex]
[tex]FK:KG=3:(4-3)[/tex]
[tex]FK:KG=3:1[/tex]
It means point K divides the segment in 3:1.
Using the section formula, we get
[tex]K=\left(\dfrac{3(8)+1(-8)}{3+1},\dfrac{3(-2)+1(10)}{3+1}\right)[/tex]
[tex]K=\left(\dfrac{24-8}{4},\dfrac{-6+10}{4}\right)[/tex]
[tex]K=\left(\dfrac{16}{4},\dfrac{4}{4}\right)[/tex]
[tex]K=\left(4,1\right)[/tex]
Therefore, the coordinates of the point K are (4,1).

Given sequence us neither arithmetic sequence nor geometric sequence.
What is sequence?"It is the list of elements arranged in particular order."
What is an arithmetic sequence?"It is a sequence in which consecutive terms have common difference."
What is geometric sequence?"It is sequence in which consecutive terms have common ratio."
For given example,
we have a sequence 10; 110; 1,110; 11,110; . . .
If we take the difference between consecutive terms then it would be,
110 - 10 = 100
1110 - 110 = 1000
11110 - 1110 = 10000
this means, the difference between consecutive terms is not constant.
So, given sequence is not an arithmetic sequence.
Now, we take the ratio between consecutive terms then it would be,
110/10 = 11
1110/110 = 10.09
11110/1110 = 10.009
this means, the ratio between consecutive terms is not constant.
So, given sequence is not a geometric sequence.
Therefore, given sequence us neither arithmetic sequence nor geometric sequence.
