Answer:
x=5
Step-by-step explanation:
you are solving for x
so...
start off by figuring out what goes into 20 4 times
you can also just do 20 divided by 4 which would give you 5
just need answer.....
HEY THERE!!!!
The correct answer is 34°
They are supplementary angles (connect with a straight line) which means that their angles add up to 180° so:
180 = x + 156
34 = x

The price of a coat is reduced by 15% in a sale.
The sale price of the coat is £136.
Work out the price of the coat before the sale.
Step-by-step explanation:
Find 100% of the price:
100 - 15 = 85% (Sale price)
85% = 136
1% = 136 divide 85 = 1.6
100% = 1.6 x 100 = 160
Ans: £160

11. Find mZJHI.
Answer:
JHI = 23°
Step-by-step explanation:
Since it's a rectangle it has 4 right angles.
90= 3x + 2 + 12x -17
90= 15x -15
105= 15x
x=7°
So HJI would be 12*7 -17 = 67°
Knowing that the sum of the angles of a triangle is 180°,
67° + 90°+ JHI= 180°
JHI = 23°
Answer:
Step-by-step explanation:
we have 2 equations that we can set equal to 90. that way, we can find x and then solve the equations for themselves. angle JHI is equal to GJK, which is an angle we can easily find. here is my work:
(3x + 2) + (12x - 17) = 90
15x - 15 = 90
+ 15 + 15
15x = 105
x = 7
3(7) + 2
21 + 2
GJK = 23
so, since the two angles are congruent, that means that angle JHI = 23 degrees

Answer:
Integers are Not Closed under Division
Step-by-step explanation:
Answer:
Integers are Not Closed under Division.
Step-by-step explanation:
There are three integers between-2 and 2. ... The set of integers is closed under addition, subtraction, and multiplication because when I add, subtract, or multiply any integers, the result is always an integer. The set is not closed under division because 2 + 4 = 0.5, and 0.5 is not an integer. The integers are "closed" under addition, multiplication and subtraction, but NOT under division ( 9 ÷ 2 = 4½). (a fraction) between two integers. Integers are rational numbers since 5 can be written as the fraction 5/1.

Answer:
x = 1 [tex]y=\frac{\sqrt{3}}{2}[/tex]Step-by-step explanation:
From the given right-angle triangle
The angle = ∠60°
The adjacent to the angle ∠60° is 1/2. The opposite to the angle ∠60° is y.The hypotenuse = x
Determining the value of x:
Using the trigonometric ratio
cos 60° = adjacent / hypotenuse
substituting adjacent = 1/2 and hypotenuse = x
[tex]cos\:60^{\circ }=\:\:\frac{\frac{1}{2}}{x}[/tex]
[tex]\cos \left(60^{\circ \:}\right)=\frac{1}{2x}[/tex]
[tex]\frac{1}{2}=\frac{1}{2x}[/tex] ∵ cos (60°) = 1/2
[tex]2x=2[/tex]
Dividing both sides by 2
[tex]\frac{2x}{2}=\frac{2}{2}[/tex]
Simplify
[tex]x=1[/tex]
Thus, the value of hypotenuse x is:
x = 1
Determining the value of y:
Using the trigonometric ratio
sin 60° = opposite / hypotenuse
As we have already determined the value of hypotenuse x = 1
substituting opposite = y and hypotenuse = 1
sin 60° = y/1
y = 1 × sin 60°
[tex]y=\frac{\sqrt{3}}{2}[/tex] ∵ [tex]\sin \left(60^{\circ \:}\right)=\frac{\sqrt{3}}{2}[/tex]
Therefore, the value of y is:
[tex]y=\frac{\sqrt{3}}{2}[/tex]
Summary:
x = 1 [tex]y=\frac{\sqrt{3}}{2}[/tex]Help me pls....
Find the distance on the map, in cm, which represents an actual distance of 14.4 km
Answer:
14.4 km = 1440000
Step-by-step explanation:
1 km = 1000m
14.4 km = 1000 ×14.4
=14400 m
1 m =100 cm
14400 m = 100 × 14400
= 1440000 cm

determine a similarity transformation that maps the primage to the image.
Answer:
Step-by-step explanation:
From the figure attached,
ΔABC has been dilated to form another triangle ΔA'B'C'.
Therefore, ΔA'B'C' is the image triangle of preimage ΔABC.
Coordinates of preimage ΔABC are,
A(3, 3), B(2, 0) and C(5, 2)
Coordinates of ΔA'B'C',
A'(6, 6), B'(0, 4) and C'(10, 4)
Since, dilation of a triangle is a similarity transformation which produces the similar image of the preimage.
Rule for the dilation is,
(x, y) → (kx, ky)
Here, k = scale factor of dilation
By this rule,
A(3, 3) → A'(6, 6)
→ A'(2×3, 2×3)
Scale factor = 2
Therefore, "Triangle (ABC) is dilated by a scale factor 2 about the origin to form triangle (A'B'C') ".
Lupe and her friends spend $20 on hot dogs and popcorn at a
sporting event. Hot dogs cost $2.50 each, and popcorn costs $1.00
each. They buy a total of 11 items at the concession stand. How
many of each item do they buy?
Answer:
They buy 6 hotdogs and 5 popcorn
Step-by-step explanation:
Assume that they buy x hotdogs and y popcorn
∵ They buy a total of 11 hotdogs and popcorn
∵ The number of hotdogs is x and the number of popcorn is y
∴ x + y = 11 ⇒ (1)
∵ Hot dogs cost $2.50 each
∵ Popcorn costs $1.00 each
∵ They spend $20 on hot dogs and popcorn
→ Multiply x by 2.5 and y by 1, add the products and equate the sum by 20
∴ 2.5(x) + 1(y) = 20
∴ 2.5x + y = 20 ⇒ (2)
Now we have a system of equations to solve it
→ Subtract equation (1) from equation (2)
∵ (2.5x - x) + (y - y) = (20 - 11)
∴ 1.5x + 0 = 9
∴ 1.5x = 9
→ Divide both sides by 1.5 to find x
∴ x = 6
→ Substitute the value of x in equation (1) to find y
∵ 6 + y = 11
→ Subtract 6 from both sides
∴ 6 - 6 + y = 11 - 6
∴ y = 5
∴ They buy 6 hotdogs and 5 popcorn

John is measuring a piece of glass to fit in a triangular frame. He can only remember
two sides of the frame, which are 6 centimeters and 11 centimeters. Between what
two numbers must the third side of the frame fall?
A. X < 17
B. X > 5
C.5< X < 17
D. 5 ≤ X ≤ 17
Answer: (c)
Step-by-step explanation:
Given
length of two sides of a triangle is 6 cm and 11 cm
In a triangle length of the third side lies between the sum and subtraction of the other two sides
Suppose x is the length of the third side so

A company rents out 11 food booths and 28 game booths at the county fair. The fee for a food booth is $200 plus $9 per day. The fee for a game booth is $95 plus $6 per day. The fair lasts for d days, and all the booths are rented for the entire time. Enter a simplified expression for the amount, in dollars, that the company is paid.
Step-by-step explanation:
Total company pay
= Pay for food booths + Pay for game booths
= 11($200 + $9d) + 28($95 + $6d)
= $2200 + $99d + $2660 + $168d
= $4860 + $267d
= $3(1620 + 89d).
