1. A rectangular room measures 13 feet by 15 feet. It is going to be carpeted 1 point with carpeting that sells for $31.50 per SQUARE YARD. (A square yard is 3 feet by 3 feet, or 9 square feet)... So, this carpet sells for 31.50/9 or $3.50 per square foot. b. If the room is drawn to 1/4 inch represents 1 foot scale, give the dimensions of the room in inches on the scale drawing."
Answer:
The dimensions of the room in inches on the scale drawing is
[tex]3\frac{1}{4}[/tex] inches by [tex]3\frac{3}{4}[/tex]inches OR 3.25 inches by 3.75 inches
Step-by-step explanation:
From the question, the dimension of the room is 13feet by 15feet.
Now, if the room is drawn to 1/4 inch represents 1 foot scale, i.e 0.25 inch represents 1 foot, then the dimension of the room in inches on the scale drawing can be determined as follows
Since 1 foot = 0.25 inch
∴ 13 feet on the scale drawing will be 13 × 0.25 = 3.25 or 3 1/4 inches
and 15 feet on the scale drawing will be 15 × 0.25 = 3.75 or 3 3/4 inches
Hence, the dimensions of the room in inches on the scale drawing is
[tex]3\frac{1}{4}[/tex] inches by [tex]3\frac{3}{4}[/tex]inches OR 3.25 inches by 3.75 inches.

A balloon lifts off the ground and reaches a height of 200m. The total mass of the balloon is 1000 kg. What is the GPE of the balloon?
Answer:
1,960,000Joules
Step-by-step explanation:
Gravitational Potential Energy is expressed as;
GPE = mgh
m is the mass
g is the acceleration due to gravity
h is the height
Given
m = 1000kg
h = 200m
g = 9.8m/s
Substitute;
GPE = 1000 * 9.8 * 200
GPE = 9800 * 200
GPE = 1,960,000Joules
Hence the GPE of the balloon is 1,960,000Joules

Answer:
The value is 0.025
Step-by-step explanation:
We get the z-score that is equal to the given value
Mathematically we have this as:
z-score = (x-mean)/SD
x = 93
mean =79
SD = 7
So we have the z-score as;
z-score = (93-79)/7 = 14/7 = 2
So we want to calculate the probability equal to the calculated z-score value of 2
Using the standard normal distribution table, we have this value as;
1 - 0.975= 0.025
Can the sides of a triangle have lengths 3, 16, and 19?
The answer is no. The Triangle Inequality Theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third.
Answer:
No
Step-by-step explanation:
Because you have to add the smallest ones which are 3 and 16 if u add them up it = 19 and you cant have 19 , 19 you have to have the smallest numbers ADD UP Greater Than the biggest number, when its equal to itself it doesn't form a triangle because the lengths are short by 1 please tell me if u need more help
Kyle held a balloon 8 feet off the ground, straight above his head. Ava is standing 15 feet directly to the right of Kyle.
Complete Question:
Kyle held a balloon 8 feet off the ground, straight above his head. Ava is standing 15 feet directly to the right of Kyle.
Write an equation using the Pythagorean Theorem to find the value of x.
How far are Ava's feet from the balloon?
Answer:
Ava's feet is 17ft away from the balloon
Step-by-step explanation:
Given
[tex]height = 8ft[/tex]
[tex]distance = 15ft[/tex]
The attached image represents the scenario
Using Pythagoras theorem (from the attachment), we have:
[tex]x^2 = 8^2 + 15^2[/tex]
[tex]x^2 = 64 + 225[/tex]
[tex]x^2 =289[/tex]
Take square roots of both sides
[tex]x = \sqrt{289[/tex]
[tex]x = 17[/tex]

Answer:
(6, - 1 )
Step-by-step explanation:
Given the 2 equations
2x + y = 11 → (1)
[tex]\frac{1}{2}[/tex] x - 5y = 8 ← (2)
Multiplying (2) by - 4 and adding to (1) will eliminate the x- term
- 2x + 20y = - 32 → (3)
Add (1) and (3) to eliminate x
0 + 21y = - 21
21y = - 21 ( divide both sides by 21 )
y = - 1
Substitute y = - 1 into either of the 2 equations and solve for x
Substituting into (1)
2x - 1 = 11 ( add 1 to both sides )
2x = 12 ( divide both sides by 2 )
x = 6
solution is (6, - 1 )

Step-by-step explanation:
From looking at this figure we could break it up into 3 different shapes and find the area of each giving us the area of the shape by adding.
Area of a square formula: A=LW
Area of a triangle formula: A=1/2bh
Rectangle:
A=8 x 4
A=32
Triangle 1:
A=1/2bh
A=1/2(3)(2)
A=3
Triangle 2:
A=1/2bh
A=1/2(3)(3)
A=4.5
Now add them all together to get your area of the figure.
32+3+4.5=39.5
Area=39.5

Answer:
Do you have a diagram to follow?
It will much help, and easier for answering.
The radius of the other similar circle is, 6 inches
What is a circle?In mathematics, the circle is a two dimensional rounded figure which has no corner edges.
Standard form = (x - a)² + (y - b)² = r²
Angle = Arc / Radius
Given that,
The two arc lengths for the circles are equal
One circle has a radius of 8 inches and a shaded sector with an angle measure of 90 degrees
The second circle has a shaded sector with an angle measure of 120 degrees
The radius of second circle = ?
α = 90°
It is known that,
π radian = 180°
1° = π/180 radian
Now,
α = 90 × π/180
= π/2
β = 120°
= 120 × π/180
= 2π/3
In Circle 1,
Angle = Arc / Radius
π/2 = Arc/8
Arc = 4π
In both the circles, length of arc is same,
In Circle 2,
Angle = Arc / Radius
2π/3 = 4π/Radius
Radius = 6
Thus, the radius of second circle is 6 inches

The measure of ⏜ is 161°, and the measure of ⏜ is 107°.
What is the measure of ∠ ?
Answer:
m<AEB = 46°
Step-by-step explanation:
Given:
Arc AD = 161°
Arc BC = 107°
Required:
m<AEB
Solution:
Vertex angle = ½(sum of intercepted arcs) => Theorem for angle inside a circle and its intercepted arcs)
This:
m<AED = ½(AD + BC)
m<AED = ½(161 + 107) => Substitution
m<AED = ½(268) = 134°
✔️m<AEB = 180° - m<AED => Linear pair theorem
m<AEB = 180° - 134° => substitution
m<AEB = 46°

Francesca is growing 1/2 inch in each year. How many years will it take for her to grow 6 inches
Answer:
The number of years it will take for Francesca to grow 6 inches is 12 years
Step-by-step explanation:
The height to which Francesca is growing, Δh/Δt = 1/2 inch per year
The number of years, 'Δt', it will take her to grow 6 inches given as follows;
Δh/Δt = 1/2 inch/year
Δh = 1/2 inch/year × Δt
When Francesca grows 6 inches, we have;
Δh = 6 inches
∴ Δh = 6 inches = 1/2 inch/year × Δt
6 inches = 1/2 inch/year × Δt
Δt = 6 inches/(1/2 inch/year) = 12 years
The number of years it will take for Francesca to grow 6 inches, Δt = 12 years
