The square pyramid shown below has a base with sides of 10 units. The slant height of the pyramid is 8 units. What is the vertical height, h?
Make a right triangle by using half the base and using the Pythagorean theorem calculate the height.
Height = sqrt(8^2 - 5^2)
Height = sqrt(64 - 25)
Height = sqrt(39)
Height = 6.245 ( Round the answer as needed).
Answer:
6.2
Step-by-step explanation:
We can use the Pythagorean Theorem to find h.
The equation for the Pythagorean Theorem is a^2+b^2=c^2
We see that the hypotenuse of the right triangle is 8. One leg is h. The other leg is 5 , which is half the length of the base.
We have:
a^2+b^2=c^2
5^2+h^2=8^2
25+h^2=64
h^2=39
h= square root of 39
h = 6.244

Sum of 2 numbers is 36. The larger is 3 more than twice the
smaller number, Find the smaller number below.
Answer:
11
Step-by-step explanation:
so we just make a system of equations:
x+y=36
say that x is the larger and y is the smaller
x-3=2y
so we can combine the equations and solve for x and y
re-arrange x-3=2y to be x=2y+3
x+y=36
x=2y+3
insert the value for x into x into x+y=36
2y+3+y=36
3y+3=36
y=11
now insert that back into x+y=36
11+x=36
x=25
Out of the two numbers x and y, 11 is the smaller number

Answer:
[tex]\frac{8}{25}[/tex]
Step-by-step explanation:
Convert 32% to the fraction [tex]\frac{32}{100}[/tex]Since any percentage is out of 100, we make 100 the denominator.
[tex]\frac{32}{100}[/tex] can be simplified because both 32 and 100 can be divided by 4 evenly.32/4 = 8 100/4 = 25This makes the fraction [tex]\frac{8}{25}[/tex]If buyers and sellers expect higher gasoline prices next week,
a. demand increases and supply decreases today, therefore the equilibrium price increase today

Step 1: Identify
Leg a = 7.5
Leg b = 10
Hypotenuse c = c
Step 2: Solve for c
Substitute in variables [Pythagorean Theorem]: 7.5² + 10² = c²Rewrite: c² = 7.5² + 10²Evaluate exponents: c² = 56.25 + 100Add: c² = 156.25[Equality Property] Square root both sides: c = 12.5Combine like terms to simplify 12x+4y-3x+2-8y²+3²

x – 5 and x + 2
x – 2 and x + 5
x and x + 3
x + 3 and x – 10
Answer:
x - 2 and x + 5

How many more consecutive free throws would he need to make to raise his free throw percentage to 75%?
Answer:
Need ( 3 ) more consecutive free throws to make to raise his free throw percentage to 75%
A percentage is a way to describe a part of a whole. To raise his free throw percentage to 75% he needs to make 3 more baskets.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.

Over the last 3 evenings, Huda received a total of 94 phone calls at the call center. The third evening, she received 3 times as many calls as the second evening.
The second evening, she received 9 fewer calls than the first evening. How many phone calls did she receive each evening?
Please answer??
Answer: See explanation
Step-by-step explanation:
Let the number of calls received the first evening be x.
The second evening, she received 9 fewer calls than the first evening. This will be: = x - 9
The third evening, she received 3 times as many calls as the second evening. This will be: = 3(x - 9) = 3x - 27
Then, the expression for each evening can then b put together and solved further as:
x + (x - 9) + (3x - 27) = 94
x + x - 9 + 3x - 27 = 94
5x = 94 + 9 + 27.
5x = 130
x = 130/5
x = 26
First evening = 26 calls
Second evening = x - 9 = 26 - 9 = 17 calls
Third evening = 3x - 27 = 3(26) - 27 = 78 - 27 = 51 calls

Find the equation of a line that passes through the point (-2,4) and has a gradient of -3.
Leave your answer in the form
y
=
m
x
+
c
Equation of a line is y = mx +c
m is the gradient, which is given as -3 so now you have:
y = -3x + c
Replace y and x with the given point and solve for c:
4 = -3(-2) + c
Simplify:
4 = 6 + c
Subtract 6 from both sides:
c = -2
The equation becomes:
y = -3x-2
