Answer: 100
Step-by-step explanation:
Since she had a mean score of 94 in her 5 tests, then the total score will be:
= 94 × 5
= 470
Since she She remembered getting scores of 97, 88, 90, and 95, for 4 quizzes out of 5 quizzes, the total of the four quizzes will be:
= 97 + 88 + 90 + 95
= 370
Then, her 5th quiz will be:
= 470 - 370
= 100
For the following right triangle, find the side length x. Round your answer to the nearest hundredth. X, 18, and 10
Answer:
152
Step-by-step explanation:
All segments in a triangle add to 180. 1
8+10+x=180
x=152
The length x using Pythagoras theorem is 15 unit.
What is Pythagoras theorem?According to the Pythagorean theorem, the square of the hypotenuse of a right triangle equals the sum of the squares of the other two sides.
Given:
Hypotenuse = 18 unit
Perpendicular = 10 unit
using Pythagoras theorem
H² = P² + B²
18² = 10² + B²
324 = 100 + B²
324 - 100 = B²
B² = 224
B= 14.966 unit
B= 15 unit
Thus, the measure for x is 15 unit.

What is the volume of a cone that has a height of 10 feet and a base with a surface area(B) of 9 square feet?
Answer:
30 cubic feet
Step-by-step explanation:
According to the scenario, calculation of the given data are as follows,
Height of cone (h) = 10 feet
Base surface area = π[tex]r^{2}[/tex] = 9 sq. feet
So we can calculate the volume of cone by using following formula,
volume of cone = (1/3)π[tex]r^{2}[/tex]h
By putting the value in the formula, we get
Volume of cone = (1/3) 9 × 10
= 3 × 10
= 30 cubic feet

What is the average rate of change for this exponential function for the interval from x = 7 to x = 8?
Answer:
4374
Step-by-step explanation:
Since, we are given table for x and y values
and table for average rate of changes
we can see the pattern of average rate of change
average rate of change for 5 to 6 is three times average rate of change for 4 to 5
but we have to find
average rate of change for 7 to 8
so, using same pattern
average rate of change for 6 to 7 is three times average rate of change for 5 to 6
average rate of change for 7 to 8 is 3*3( average rate of change for 5 to 6)
so, we can plug value
average rate of change for 7 to 8 is 3*3*486
average rate of change for 7 to 8 is 4374

Answer:
NA
a = 53
Step-by-step explanation:
A bisector creates two equal angles. Set them equal to each other.
5a - 160 = 2a - 1 ( subtract 2a from both sides)
3a = 159 (add 159 to both sides)
a = 53 (divide by 3)

How many \frac{1}{2} 2 1 - pound packages of cheese can the deli make with 1212 pounds of cheese?
Given:
Total cheese = 12 pound
Cheese in each package = [tex]\dfrac{1}{2}[/tex] pounds
To find:
The number of cheese packages.
Solution:
We need to divide the total amount of cheese by quantity of cheese in each package to find the the number of cheese packages.
[tex]\text{Number of cheese packages}=\dfrac{\text{Total cheese}}{\text{Cheese in each package}}[/tex]
[tex]\text{Number of cheese packages}=\dfrac{12}{\dfrac{1}{2}}[/tex]
[tex]\text{Number of cheese packages}=12\times \dfrac{2}{1}[/tex]
[tex]\text{Number of cheese packages}=24[/tex]
Therefore, there are 24 number of cheese packages.
Which represents the explicit formula for the arithmetic sequence on = 7 - 3(n - 1) in function form?
f(n) = 3n - 6
B f(n) = -3n - 6
f(n) = 3n - 10
D f(n) = -3n + 10
Answer:
Step-by-step explanation:
All this question is asking you to do is distribute through the parenthesis to simplify. Doing that gives us
f(n) = 7 - 3n + 3 and
f(n) = 10 - 3n or
f(n) = -3n + 10, choice D.
The representation of the function of the given arithmetic sequence 7 - 3(n - 1) is f(n) = -3n + 10 thus option (D) is correct.
What is a function?An arrangement known as a function connects inputs to essentially one output.
The machine may only produce one output for each input and will only accept inputs that are specifically listed as part of the function's domain.
As per the given,
a_n = 7 - 3(n - 1)
f(n) = 7 - 3n + 3
f(n) = -3n + 10
Hence "The representation of the function of the given arithmetic sequence 7 - 3(n - 1) is f(n) = -3n + 10".

you can know this by dividing the sugar by the pies
then you can multiply 12 by 3/4 to find how many cups are needed for 12 pies, which is 9
Answer:
9
Step-by-step explanation:
6 devided by 2 is three
8 divided by two is four
four times three makes the amount of pies you need

Answer:
-1.2
Step-by-step explanation:
3n + 5 = 1/2(11n + 16)
3n + 5 = 5.5n + 8
5 = 2.5n + 8
-3 = 2.5n
-3/2.5 = n
-1.2 = n
Hope this helps!
Answer:
[tex]n=-1.2[/tex]
Step-by-step explanation:
First, solve both sides of the equation:
[tex]3n+5=\frac{1}{2} (11n+16)[/tex]
[tex]3n+5=(\frac{1}{2} )(11n)+(\frac{1}{2} )(16)[/tex] (Distribute)
[tex]3n+5=\frac{11}{2} n+8[/tex]
Then, subtract 11/2 n from both sides:
[tex]3n+5-\frac{11}{2}n=\frac{11}{2} n+8-\frac{11}{2} n[/tex]
[tex]\frac{-5}{2}n+5=8[/tex]
Now, subtract 5 from both the sides:
[tex]\frac{-5}{2} +5-5=8-5[/tex]
[tex]\frac{-5}{2} n=3[/tex]
For the last step, multiply both the sides by 2 / -5
[tex](\frac{2}{-5} )*(\frac{-5}{2} )=(\frac{2}{-5} )*(3)[/tex]
[tex]n=\frac{-6}{5}[/tex]
Convert it to decimal:
