Scott received a score of 91, 85, and 89 on three tests. What score must Scott get on the fourth test to have an overall average score of 90
Answer:
95
Step-by-step explanation:
So if you wanted to figure the average of the 3 tests, you would add 91+85+89 to get 265 & then divide by 3 tests to get an average of 88.
So that means for four tests, 91+85+89+4th test = answer that divided by 4 tests will equal 90. 90 x 4 = 360. Then 360 -265 (sum for 1st 3 tests) = 95

a
how many visits must tyler make to earn a free movie ticket?
Answer:
at least 10 visits
Step-by-step explanation:
Given:
75 rewards points for signing up
10.5 points for each visit
Total Number of Points are :
75 + 10.5 · number of visits he makes
How many visits must Tyler make to earn a free movie ticket?
75 + 10.5 · x ≥ 180 points for a free movie ticket
Where, x is how many visits must Tyler make to earn a free movie ticket
10.5 · x ≥ 180 -75
x ≥ 105/ 10.5
x ≥ 10
Since the number of visits to reach 180 points is 10 then Tyler has to visit the movie theater 10 times or more.
Check our answer:
75 + 10.5 · 10 = 180 will earn him a free movie ticket

An equation is formed of two equal expressions. The solution of the equation √(x+12)=x is x=4.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The solution of the equation √(x+12)=x can be done as,
[tex]\sqrt{x+12} = x\\\\\text{Square both the sides of the equation}\\\\x+12=x^2\\\\x^2-x-12=0\\\\x^2-4x+3x-12=0\\\\x(x-4)+3(x-4)=0\\\\(x-4)(x+3)=0[/tex]
Equate each of the factors with 0,
[tex](x-4)=0\\x=4\\\\(x+3)=0\\x=-3[/tex]
Now, if we substitute the value of x in the equation given, only the value of x as 4 will satisfy the equation.
Thus, the solution of the equation √(x+12)=x is x=4.

Answer:
Area of composite shape = 36 square units
Step-by-step explanation:
Area of composite shape:
Rectangle I:
Length = 3 units
width = 6 - 4 = 2 units
Area of rectangle I = length *width
= 3* 2
= 6 square units
Rectangle II:
length = 6 units
width = 5 units
Area of rectangle II = 6 * 5
= 30 square units
Area of composite shape = area of rectangle I + area of rectangle II
= 6 + 30
= 36 square units

Lucy Garcia took out a loan for $40,000 at 10 percent interest for 10 years. Her monthly payments are $528. 60. She made payments for one year and has paid the principal down to $37,546. 36. She now wants to repay the loan early. The loan specifies a $300 prepayment penalty if she pays the loan now. How much will she save by paying the loan early (round final answer to nearest dollar)?
The amount saved due to early payment is $19,242
Data;
Monthly payment = 528.60Number of payment = 10 years * 12 = 120 Total payment if not prepaid = 528.60 * 120 = $63,432Total Payment for the whole termThe total payment for the whole term is the equal to the product of monthly payment and the number of payment as calculated above.
The total amount in cash in case of prepayment is
[tex]total amount in case of prepayment = monthly payment * number completed + balance + penalty[/tex]

All sides add up to the perimeter. The perimeter of the kite is 27 units then the correct option is C.
What is the definition of geometry?It is concerned with the geometry, region, and density of various 2D and 3D forms.
The Pythagoras theorem will determine the kite's length (x).
H² = P² + B²
H² = 15² + 8²
H² = 225 + 64
H² = 289
H = 17
Then

What is the area of a parallelogram with a base of 26 m and a height of 18 m?
Answer:
468 m²
Step-by-step explanation:
Given:
→ Base = 26 m
→ Height = 18 m
Formula:
[tex]\text{Area of parallelogram: Base} \times \text{Height}[/tex]
To determine the area of the parallelogram, we need to substitute the base and the height in the formula.
Substitute the measures in the formula:
[tex]\implies \text{Area of parallelogram: Base} \times \text{Height}[/tex]
[tex]\implies \text{Area of parallelogram} = 26 \times 18[/tex]
Evaluate the area of the parallelogram:
[tex]\implies \text{Area of parallelogram} = 26 \times 18[/tex]
[tex]\implies \text{Area of parallelogram}= \bold{468 \ \text{m}^{2}}[/tex]
Answer:
468 m²
Step-by-step explanation:
Given,
Base ( b ) = 26 m
Height ( h ) = 18 m
To find : The area of parallelogram
Formula : -
Area of parallelogram = bh
Area of paralleogram
= 26 x 18

please find the area of the shaded region
Answer:
Step-by-step explanation:
Remark
The way to solve the shaded region is to find the area of the square first and subtract the area of the circle from it.
Area of the square
Area = s^2
s = 12
Area of the square = 12 * 12
Area of the square = 144 yd^2
Area of the circle = pi * r^2
r = d/2
d is actually the same as the side length of the square
r = 12/2
r = 6
pi = 3.14
Area of the circle = pi * 6^2
Area of the circle = 3.14 * 36
Area of the circle = 113.04
Area of the shaded region
Area of shaded region = area of the square - area of circle
Area of shaded region = 144 - 113.04
Answer: Area of the shaded region 30.96
