The Surface Area of Pyramid is 104 cm².
What is Surface Area?Simply calculating the areas of each face in a figure is surface area. It is considerably simpler for us to calculate because the amount is supplied to us as a net of.
So, Area of square base= (side²)
= 8²
= 64 cm²
and, Area of one triangular face
= (1/2 x b x h)
=1/2 x 8 x 5
= 20 cm²
Now, Multiply by 4 as we have 4 triangular faces
= 20 cm² x 4
= 80 cm²
Then, Surface Area of Pyramid is
= 64 cm² + 40 cm²
= 104 cm²

Susan estimated she would spend $250 on school clothes at the start of the school year. She actually ended up spending only $230. What was her percent of error in her calculations?
Answer:
8.7%
Step-by-step explanation:
the formula for % error is = [ (approx. - exact ) / exact ] x 100
so, we know the approx value was 250 while the exact one is 230
thus; [ ( 250-230 ) / 230 ] x 100
= 8.7%

Answer:
MN = 4 units
m<MLN = 42 degrees
Step-by-step explanation:
For this problem, we need to know the definition of congruence. Two shapes are said to be congruent if the angles and sides have the exact same measurements.
We are given that these two triangles are congruent, so we know they are the same. XYZ ~= NML
Since we know this, we simply rotate the triangles to be the same to know the measurements.
We know that XY = MN = 4 units.
We know that m<YZX = m<MLN = 42 degrees.
So, these are the solutions.

A sphere with a radius of 21cm JUST fits in a cube-shaped box. Calculate the amount of empty space in the box rounded to the nearest tenth of a cubic centimetre.
How do you solve this?
Answer:
Since its a cube and a sphere just fits in side it we know that both the sphere and the cube are 21cm wide and since its a cube the dimensions of the cube is 21*21*21 giving you 9,261 cm³ then you find the volume of the V=4/3π10³≈4849.04826 now all you have to do is subtract your two totals to get 4411.95174
Step-by-step explanation:
Brₐinliest plz
Answer:
35,295.6 cm^3 to the nearest tenth.
Step-by-step explanation:
The diameter of the sphere = 2*21 = 42.
The volume of the box = 42^3 ( because the dimensions of the box = the diameter of the sphere).
The volume of the sphere = 4/3 π r^3
= 4/3 π 21^3
So the empty space = 42^3 - 4/3 π 21^3
= 35295.615 cm^3.

Sally designed a gold bracelet using 8 thin gold circles, arranged each circle has a radius of 2.5 what is the diameter and what is the length '5cm' of the chain
Answer:
Diameter of the circle = 5.0 unit
The length of the chain = 40 units
Step-by-step explanation:
Given
Number of thin gold circles used for making bracelet is equal to 8
Radius of the circle = 2.5 units
Diameter of the circle = 2 * Radius of the circle
Diameter of the circle = 2 * 2.5 = 5.0 unit
The length of the chain = 8 * diameter = 8 * 5 = 40 units
Martin is considering the expressions 12(7x+48) and −(12x−3)+4(x+5). He wants to know if one expression is greater than the other for all values of x. Show or explain how you found your answer to Part A. Enter your work or your explanation in the box provided.Write a new expression that always has a greater value than both of these expressions. Enter your expression in the box provided.
Answer:
Part A
The first thing we must do for this case is to rewrite both expressions.
We have then:
1/2 (7x + 48) = (7/2) x + 24
- [1 / 2x - 3] + 4 (x + 5) = - (1/2) x + 3 + 4x + 20 = (7/2) x + 23
Answer:
We note that the first expression is greater than the second for all values of x.
Part B:
A new expression that is greater than both written expressions is:
(7/2) x + 25
For all values of x, this expression is always greater.
Answer:
(7/2) x + 25

How many credit hours a student have to take for the two tuition cost to be equal round the answer to the nearest 10th of an hour 250+200 H equals 300+180 250+200 H equals 300+180-180-180 H 250+20 = 300 H equals credit hours
Answer:
Total credit hours a student have = 2.5 hours.
Step-by-step explanation:
P.S - The exact question is -
Given - The tuition costs, C, for a local community college are modeled by C(h) = 250 + 200h, where h represents the number of credit hours taken. The local state university has tuition costs, S, modeled by the function S(h) = 300 + 180h.
To find - How many credit hours will a student have to take for the two tuition costs to be equal.
Proof -
If the two tuition cost are equal, then
C(h) = S(h)
⇒250 + 200h = 300 + 180h
⇒200h - 180h = 300 - 250
⇒20h = 50
⇒2h = 5
⇒h = [tex]\frac{5}{2}[/tex]
⇒h = 2.5
∴ we get
Total credit hours a student have = 2.5 hours.

How do u work the problem m/-14 < -4 out
Answer:
m = 56
Step-by-step explanation:
The same way you would solve an equation.
m/-14 < -4
multiply both sides by -1
-1(- m/14) < -1 (-4)
since you are multiplying by a negative number, invert the inequality sign
m/14 > 4
multiply both sides by 14
m = 4 * 14
m = 56

Answer:
the trid one becasue
Step-by-step explanation:
To get the correct answer, you can count the total number of shaded tenths and the total number of shaded hundredths and then regroup.
There are 9 shaded tenths and 18 shaded hundredths. Regroup 10 hundredths into 1 tenth to get 10 tenths and 8 hundredths. Then regroup the 10 tenths in one whole, giving you 1 whole and 8 hundredths. The product is 1.08.
Another way to get the answer is to count the total number of shaded hundredths. There are 108 hundredths. Regroup 100 of them as one whole, giving you 1 whole and 8 hundredths.
Option A is correct, the product of (√14 - √3) (√12+√7) is 2√42-7√2-6-√21
What is Expression?An expression is combination of variables, numbers and operators.
We need to find the product of (√14 - √3) (√12+√7)
Let us apply distributive property to solve this
√14(√12+√7) - √3(√12+√7)
√14.√12 + √14√7 -√3√12-√3√7
√168 + √98 -√36 -√21
168 can be written as 4 times of forty two.
98 can be written as forty nine times of 2.
So we get
2√42-7√2-6-√21
Hence, Option A is correct, the product of (√14 - √3) (√12+√7) is 2√42-7√2-6-√21
