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 )

Crystal earns $5.50 per hour mowing lawns.
a. Write a rule to describe how the amount of money m earned is a function of the number of hours h spent mowing lawns.
b. How much does Crystal earn if she works 3 hours and 45 minutes?
m(h) = 5.50h; $18.98
m(h) = [tex]\frac{h}{5.50}[/tex]; $0.68
m(h) = 3h + 45; $61.50
m(h) = 5.50h; $20.63
Answer:
For this case, the first thing we must do is define a variable:
h: number of hours worked.
We now write the equation that models the problem:
So, for 3 hours and 45 minutes we have:
Remember that we have the following conversion:
1 hour = 60 minutes
Substituting values:
Answer:
Crystal earns about:
m = $ 20,625
Step-by-step explanation:
Answer:
1) Required equation
2)Crystal earns $20.625 in 3 hours and 45 minutes.
Step-by-step explanation:
Given : Crystal earns $5.50 per hour mowing lawns.
To find :
1) Write a rule to describe how the amount of money m earned is a function of the number of hours h spent mowing lawns.
It is given that Crystal earns $5.50 per hour mowing lawns.
Let m is the amount of money earned
and h is the number of hours spent
So, The equation form by the statement is
2) How much does Crystal earn if she works 3 hours and 45 minutes
1 hour=60 minutes
So, for 3 hours and 45 minutes
In 1 hour she earn $5.50
In 3.75 hours she earn
Crystal earns $20.625 in 3 hours and 45 minutes.

A right square pyramid has a base with sides that are 2 inches in length and a slant height of 7 inches. If the lengths of the sides of the base and the slant height are multiplied by 7, by what factor is the surface area multiplied? A. 7 B. 14 C. 28 D. 49
Answer:
Step-by-step explanation:
base b = 2 in
slant height L = 7 in
lateral area = 4·½bL = 4·½·2·7 = 28 in²
base area = b² = 4 in²
surface area = 28+4 = 32 in²
If b = 14 and L = 49:
lateral area = 4·½·14·49 = 1372 in²
base area = 196 in²,
and surface area = 1372+196 = 1568 in²
The surface area has multiplied by 49.

49

Solve for x based on the following system of equations:
x + y = 5
2x + 3y = 20
-10
-5
-2
5
10
Answer:
x = -5
Step-by-step explanation:
x + y = 5 can be also written as 3x + 3y = 15 by times 3 on both side, let it be equation (1), then let 2x + 3y = 20 be equation (2), then use equation (2) - (1), can get (2x - 3x) + (3y - 3y) = 20 - 15 ---> -x = 5, then x = -5.
The foot of a ladder is placed 18 feet from a wall. If the top of the ladder
rests 24 feet up on the wall, find the length of the ladder.
26 feet
27 feet
29 feet
O 30 feet
Answer:
I'm not sure
I think its 30 or 26
Step-by-step explanation:
Answer:
30 feet
Step-by-step explanation:
The ladder laying against the wall will create a right triangle.
The side lengths will be 18 and 24 and you will solve for the hypoteneuse which will be the length of the latter.
You can use the pythagorean theorm so
[tex]a^{2} +b^{2} =c^{2}[/tex] so you plug in the values
[tex]18^{2}+24^{2} =c^{2} \\324+576=c^{2} \\900=c^{2} \\\sqrt{900} =\sqrt{c^{2} } \\30=c[/tex]
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.
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.

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

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°
