Answer:
5
Step-by-step explanation:
W = x
L = x + 3
P = 2W + 2L
26 = 2(x) + 2(x + 3)
26 = 2x + 2x + 6
26 = 4x + 6
26 - 6 = 4x
20 = 4x
x = 5

The area sector of a circle with radius 7 is 9 π/. What is the radian measure θ, the central angle of the sector? Express your answer in exact form.
Answer:
Radian angle = 1.154
Central angle = 66.123°
Step-by-step explanation:
Area of Sector, A
A = 1/2 * r² * θ ; θ measured in radian
A = 9 π
r = 7
9 π = 1/2 * 7² * θ
9 π = 24.5θ
θ = 9 π / 24.5
θ = 1.154 radian
1 radian = 57.296°
1.154 radian = (57.296 * 1.154)
1.154 radian = 66.123°
2. A square had a side length of 5x units. A triangle has side lengths of 5x, (4x+14), and (5x+4) units, For what value of x, will the square and triangle have the same perimeter?
A 2
B 4
C 5
D 3
Answer:
Step-by-step explanation:
for the square, it's got 4 sides so
4(5x) = 5x + 4x+14 +5x + 4
20x = 14x +18
6x = 18
x = 3

What is the volume of a ball if its diameter is 6 inches? Leave your answer in terms of π.
A) V = 12 π cubic inches
B) V = 36 π cubic inches
C) V = 288 π cubic inches
D) V = 27.75 π cubic inches
Answer:
B
Step-by-step explanation:
I am assuming that this ball is a perfect sphere.
The volume of a sphere is [tex]\frac{4}{3} *\pi *r^3[/tex]
We have the diameter, and in order to find the radius, we just have to divide by 2. 6/2=3. Now, we have to plug in the 3 to the equation.
[tex]\frac{4}{3} *\pi *3^3[/tex]
3 cubed is 27, so now we have [tex]\frac{4}{3} *\pi *27[/tex]
27*4/3*pi=36pi

Answer:
Option 3
Step-by-step explanation:
By applying Pythagoras theorem in the given triangle,
(Hypotenuse)² = (Leg 1)² + (Leg 2)²
x² = (9.5)² + (10.5)²
x² = 200.5
x = √(200.5)
x = 14.16
x ≈ 14.2
Therefore, measure of the unknown side is 14.2 in.
Option (3) will be the correct option.

If $500 is invested at 8% annual interest, how much will be in the account after 3 years if it's compounded quarterly?
Answer:
FV= $634.12
Step-by-step explanation:
Giving the following formula:
Initial investment (PV)= $500
Number of periods (n)= 3*4= 12 quarters
Interest rate (i)= 0.08/4= 0.02
To calculate the future value, we need to use the following formula:
FV= PV* (1 + i)^n
FV= 500*(1.02^12)
FV= $634.12

The sum of three consecutive odd integers is 189. What
are the integers?
Answer:
61, 63, 65
Step-by-step explanation:
n + n+2 + n+4 = 189
3n = 183
n = 61
Answer:
The three consecutive odd integers are 61, 63, and 65
Step-by-step explanation:
Let the three consecutive odd integers be:
n + 1, n + 3 and n + 5
Therefore:
n + 1 + n + 3 + n + 5 = 189
3n + 9 = 189
3n = 180
n = 60
n + 1 = 61
n + 3 = 63
n + 5 = 65

In Richmond, Chloe ordered $40 worth of sushi. She knew that when the bill came, she would need to pay Richmond sales tax for 5% and would want to leave a 20% tip on the original $40. including tax and tip, How much did Chloe meal cost?
Answer:
$50
Step-by-step explanation:
Given data
Cost of sushi= $40
Tax= 5%
Tip= 20%
Let us find the amount of the tax and the tip
Tax
=5/100*40
=0.05*40
=$2
Tip
=20/100*40
=0.2*40
=$8
Hence the total amount paid is
=40+2+8
=$50
Answer:
$50
Step-by-step explanation:
To avoid confusion, we can solve for the sales tax and the tip separately.
Tip
Original Bill x 20%Original Bill x 1/5$40 x 1/5$8Tax
Original Bill x 5%Original Bill x 1/20$40 x 1/20$2Total
Original Bill + Tip + Tax$40 + $8 + $2$501) You had $22 to spend on three pencils. After buying them you had $16. How much did each
