Step-by-step explanation:
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.

the model represents the equation x - 1 < -4. What is the solution for the inequality?
Answer:
any number equal to or less than -4
Step-by-step explanation:
x - 1 < -4
< represents that -4 is a larger number than x - 1. we know that -4 is a negative number, so anything below -4 would be less. x = -4 would be a good solution, but the reality is that any number equal to or less than -4 is the correct answer. I hope this helps!
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

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]

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°
find the values of the variables
Answer:
x = 31 and y= 11
Step-by-step explanation:
Since sum f angles on a straight line is 180°, hence;
2x+8+3x+17 = 180
Collect like terms
5x+25 = 180
5x = 180-25
5x = 155
x = 155/5
x = 31°
Similarly;
3x+17+5y+15 = 180
Substitute x = 31 into the equation
3(31)+17+15+5y = 180
93+32+5y = 180
125+5y =180
5y = 180-125
5y = 55
y = 55/5
y = 11°
Hence x = 31 and y= 11

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:

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

help me pretty please <3 (brainliest)
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

The value of x is 5 and y is 2 .
What is elimination method?The elimination method is the process of eliminating one of the variables in the system of linear equations using the addition or subtraction methods in conjunction with multiplication or division of coefficients of the variables.
According to the question
2x + 2y=14 ------------------- (1)
5x - 3y = 19 ------------------- (2)
Now,
solving both equation by elimination method
Multiplying equation (1) by 3 and by 2 to equation (2)
to make equal coefficient for y
So, y can be eliminated
3(2x + 2y)=14 * 3
6x + 6y = 42 -------------- (3)
2(5x - 3y) = 19*2
10x - 6y = 38 -----------------(4)
Now,
Adding both eq(3) and (4)
16x = 80
x = 5
Putting value of x in eq(1)
2*5 + 2y=14
10 + 2y = 14
2y = 4
y = 2
Hence, The value of x is 5 and y is 2 .
