For one side of the pyramid:
Since there are two symmetrical triangles on one side of the pyramid, calculate both together as a rectangle.
7x10 = 70cm
There are four equal sides to the pyramid, so multiply the area of one side by 4.
70x4 = 280cm
Finally, calculate the area of the base and add it to the total.
14x14 = 196cm
196+280 = 476cm

Answer:
5√15
Step-by-step explanation:
(√3 + √48)(√20 - √5)
step 1 simplify √48
(√3 + 4√3)(√20 - √5)
step 2 add √3 and 4√3
(5√3)(√20 - √5)
step 3 simplify √20
(5√3)(2√5 - √5)
step 4 subtract √5 from 2√5
(5√3)(√5)
step 5 multiply 5√3 and √5
= 5√15
explanation of each step
step 1 and 3
To simplify radicals you list the factors of the number under the sqaure root
For 48 we have 2 × 2 × 2 × 2 × 3
We then pair the factors off as powers of 2 if possible
We get 2² × 2² × 3 which can further be simplified as 4² × 3
We then list the number with the power on the outside of the radical and leave the numbers with no power on the inside to get 4√3.
This process is used to simplify √20 as well.
step 2 and 4
For these two steps we are adding and subtracting radicals with the same radicand ( number inside of the square root. ) This is very simply as we keep the radicand the same and just perform the operation to the coeffecients ( number on the outside of the square root )
Eg. a√b + c√b = (a+c)√b or a√b - c√b = (a-c)√b
Hence, 4√3 + √3 = (4+1)√3 = 5√3
Step 5.
Finally we multiply the two radicals. This is very simply as we can use the rule to do so.
a√b × c√d = (a×c)√b×d
Hence, 5√3 × √5 = (5×1)√(3×5) = 5√15

Answer:
Step-by-step explanation:
Given the slope-intercept form:[tex]y=\frac{1}{3}x-2[/tex]
Slope-intercept form: [tex]y=mx+b[/tex]
We substitute our x-values (-9, -3, 0, 6, and 9) for x in [tex]y=\frac{1}{3}x-2[/tex] to find the y-values.
For -9:

For 0:

A circular hot spring has a diameter of 96 meters. Over time, the diameter of the spring decreases by 8 meters. By how many square meters does the area of the hot spring decrease? Use 3.14 for pi.
about (BLANK) m2
Answers
The area decreases by 1155.52 square meters
Step-by-step explanation:What we must do is calculate the area before and after making the diameter cut.
The area of a circle is equal to:
a = pi * r ^ 2
now the diameter is equal to:
d = 2 * r
therefore r,
r = d / 2
before the cut would be
r = 96/2
r = 48
replacing in the area formula
a1 = 3.14 * 48 ^ 2
a1 = 7234.56 square meters.
after cutting the diameter decreases by 8, that is, 96 - 8 = 88, calculating the radius would be:
r = 88/2
r = 44
now calculating the new area would be:
a2 = 3.14 * 44 ^ 2
a2 = 6079.04 square meters.
now we calculate the difference
a1 - a2 = 7234.56 - 6079.04
= 1155.52 square meters
means that the area decreases by 1155.52 square meters

Answers
If you take the amount of money raised ($235) and put it over the total amount of money ($500), 235/500 will result in the decimal 0.47, and you can change that to a percentage by moving the decimal two places to the right
Assemble a fraction: 235/500.

Answers
Answer:
227.63 meters^2
Step-by-step explanation:
The formula to find an area of a parallelogram is a = bh (base multiplied by height). According to the figure, the base is 22.1 meters and the height is 10.3 meters.
a = bh
a = 22.1(10.3)
a = 227.63 meters^2

△AMC ≅ △BMC
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
CM ⊥ AB
∠3 = ∠4
We have to prove △AMC ≅ △BMC.
Now,
If CM ⊥ AB
AM = MB
Now,
AM = MB
CM = common side
∠3 = ∠4
△AMC ≅ △BMC
Thus,

A circle graph, or a pie chart, is used to visualize information and data. A circle graph is usually used to easily show the results of an investigation in a proportional manner. The arcs of a circle graph are proportional to how many percent of population gave a certain answer.
Example
An investigation was made in Mathplanet high school to investigate what color of jeans was the most common among the students. This circle graph shows how many percent of the school had a certain color. We now want to know how many angles each percentage corresponds to.
Pie 01
To find out the number of degrees for each arc or section in the graph we multiply the percentage by 360°.
Blue57%:0.57⋅360∘=205.2∘

Basketball tickets were $5 for the floor seats and $2 for the grandstand seats
If 210 people attended and paid $660, how many people bought floor seats?
Answers
Answer:
Good seats sold=80
Poor seats sold=130
Step-by-step explanation:
g + p = 210 seats. Then p = 210 - g.
($5)g + ($2)p = $660. Substite 210 - g for p,
($5)g + ($2)(210 - g) = $660
Simplify, 5g + 420 - 2g = 660 => 3g = 240 => g = 80
80 and 130
