Answer:
x = 19° ; Write 19° in the box ( don't forgot ° or answer will be incorrect )
Step-by-step explanation:
If XW ║YZ, we can tell that YW is a transversal, as YW ∩ XW, YX;
By alternate interior angles, ∠ ZYW ≅ ∠ YWX, so that ⇒
m∠ ZYW = m∠ YWX,
m∠ YWX = 2x, ⇒ given m∠ ZYW = 2x
By ∑ of angles in triangle Theorem;
m∠ YXW + m∠ XYM + m∠ YWZ = 180° ⇒ through substitution,
( 3x - 5 ) + 90 + ( 2x ) = 180 ⇒ now apply algebra,
3x - 5 + 90 + 2x = 180 ⇒ combine like terms,
3x + 2x - 5 + 90 = 180 ⇒ add,
5x + 85 = 180 ⇒ subtract 85 from either side of equation,
5x = 95, divide 5 on either side,
x = 19°
Solution; x = 19°
What is the rate of change between (29,9) and (33,10)?
Answer:
[tex]\frac{1}{4}[/tex]
Step-by-step explanation:
The rate of change is a measure of the slope
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (29, 9) and (x₂, y₂ ) = (33, 10)
m = [tex]\frac{10-9}{33-29}[/tex] = [tex]\frac{1}{4}[/tex] ← rate of change

liz is installing a tile backsplash. if each tile is an equilateral triangle with sides that measures 6 cm in length how many tiles does she need to cover an area of 1800 cm²
Answer:
116 tiles
Step-by-step explanation:
You want to know the number of 6 cm equilateral triangle tiles required to cover 1800 cm².
AreaThe area of an equilateral triangle of side s is given by the formula ...
A = (√3/4)s²
The area of a 6 cm equilateral triangle tile is ...
A = (√3/4)(6 cm²) = 9√3 cm² ≈ 15.588 cm²
TilesThe number of tiles required is the total area divided by the area per tile:
1800 cm² / (15.588 cm²/tile) ≈ 115.47 tiles
In order to cover 1800 cm², Liz will need 116 triangular tiles.
Answer:
100 tiles
Step-by-step explanation:
Each tile is an equilateral triangle with sides 6 cm in length, so the area of each tile can be found using the formula for the area of a triangle:
[tex]\sf:\implies{A = (b \times h) / 2}[/tex]
where b is the base and h is the height.
Since each side of the triangle is 6 cm, the base and height of the triangle are both 6 cm, so:
[tex]\sf:\implies{A = (b \times h) / 2}[/tex]
[tex]\sf:\implies{A = (6 \times 6) / 2}[/tex]
[tex]\sf:\implies{A =18}[/tex]
So each tile has an area of 18 cm².
To find the number of tiles needed to cover an area of 1800 cm², divide the total area by the area of each tile:
[tex]\sf:\implies{A = 1800 / 18}[/tex]
[tex]\sf:\implies{A = 100}[/tex]
Therefore, Liz needs 100 tiles to cover an area of 1800 cm².

What are the x intercept and the y intercept of this function
Answer:
D
Step-by-step explanation:
When you graph, you can see that the Line crosses the x at (-3,0) and then passes through the y at (0, 12)
Answer:
D
Step-by-step explanation:
To find the intercepts, set the variable you are not trying to find to 0. Also, in case you don't know, f(x) and y are the same thing here. So on this question, it would be:
X-Intercept:
0=4x+12
-12=4x
-3=x
so x intercept is (-3,0)
Y-Intercept:
y=4(0)+12
y=12
so y intercept is (0,12)
How do I answer this
Answer:
Step-by-step explanation:
A. Model is linear
B. y = -16x - 16
(-3, 32) (-2, 16)
(16-32)/(-2 + 3) = -16/1= -16
y - 32 = -16(x + 3)
y - 32 = -16x - 48
y = -16x - 16

Can a right triangle have the measurements of 8,11, and 13?
Answer:
yes it can
Step-by-step explanation:
yes
Answer:
No
Step-by-step explanation:
You need to use the Pythagorean Theorem. This will show you if the ratio between the sides is accurate.
a² + b² = c²
8² + 11² = 13²
64 + 121 = 169
185 ≠ 169
The measurements will not fit in a right triangle.

To make one cheese sandwich, Tina uses one bread roll and two cheese slices.
Pack of 15 bread rolls
£1.91
Pack of 20 cheese slices
£2.23
She is going to buy enough packs to
have exactly twice as many cheese slices as bread rolls
make more than 100 cheese sandwiches.
Work out the least amount she can spend.
Answer:
£42.04 is the correct answer.
Step-by-step explanation:
Cost of pack of 15 bread rolls = £1.91
Cost of pack of 20 cheese slices = £2.23
She has to buy exactly twice as many cheese slices as bread rolls.
She has to make more than 100 cheese sandwiches.
Number of bread rolls required for 100 bread rolls.
Minimum 15[tex]\times[/tex]7 = 105 bread rolls are to be bought.
105 bread rolls mean 210 cheese slices but it is a pack of 20 cheese slices.
So, at least 220 cheese slices can be bought.
But, 220/2 = 110 bread rolls are not possible to be bought.
So, at least 120 (15 [tex]\times[/tex] 8 i.e. 8 packs) bread rolls have to be bought and 120 [tex]\times[/tex] 2 = 240 (20 [tex]\times[/tex] 12 i.e. 12 packs) of sandwiches have to be bought.
So, minimum amount to be spent for at least 100 cheese sandwiches
= 1.91 [tex]\times[/tex] 8 + 2.23 [tex]\times[/tex] 12 = £42.04

A $20,000 investment earned a simple interest rate of 5.4%. How much interest was earned in one year?
Answer:
18,920.00
Step-by-step explanation:
discount = x
original price = $20,000
discount% = 5.4%
x/20,000 = 5.4/100
x · 100 = 5.4 · 20,000
100x = 108,000
100x/100 = 108,000/100
x = $ 1,080.00
Sale price = original $ - discount $ = final answer
$20,000 - $1,080 = $18,920.00
Answer:1,080
Step-by-step explanation:
20,000 x .54 equals $1,080
Justin packed two suitcases for his trip and compared the weights of the items he packed in each of the suitcases. A number line goes from 0 to 36. Suitcase 1's whiskers range from 4 to 30, and the box ranges from 8 to 12. A line divides the box at 9. Suitcase 2's whiskers range from 2 to 20, and the box ranges from 5 to 18. A line divides the box at 7. Which statement is true about the box plots? The data for suitcase 1 have an outlier, but the data for suitcase 2 does not. The data for suitcase 2 have a greater median than the data for suitcase 1. The data for suitcase 1 has a greater interquartile range than the data for suitcase 2. The data for suitcase 2 has a greater range than the data for suitcase 1.
Answer:
The correct option is;
The data for suitcase 1 have an outlier but the data for suitcase 2 does not
Step-by-step explanation:
Range of a box plot
Interquartile range (IQR) for bot suitcases we have
Here we have for suitcase 1
IQR = Q₃ - Q₁ = 12 - 8 = 4
For suitcase 2
IQR = Q₃ - Q₁ = 18 - 5 = 13
Lower outlier = Q₁ - 1.5×IQR
Higher outlier = Q₃ + 1.5×IQR
For suitcase 1 we have;
Lower outlier = 8 - 1.5×4 = 2 (No lower outlier)
Higher outlier = 12 + 1.5×4 = 18
Hence, whereby the whiskers range from 4 to 30, suitcase 1 has a higher outlier
For suitcase 2 we have;
Lower outlier = 5 - 1.5×13 = -14.5 (No lower outlier)
Higher outlier = 18 + 1.5×13 = 37.5
Hence, whereby the whiskers range from 2 to 20, suitcase 2 has no outlier.
Therefore, the correct option is the data for suitcase 1 have an outlier but the data for suitcase 2 does not.

The price of the box of 10 markers is $7. The price of the box of 24 markers is $14. All prices without tax, and the price of the boxes is the same. WILL MARK BARINLEIST OR WHATEVER YOU CALL IT I WILL
a) Write an equation which tell the price Y for the number of markers X
The linear equation where y is the price of the number of markers x is as follows:
y = 1 / 2 x + 2Let
the price of each marker = y
Therefore,
The price of a box with 10 markers = $7
The price of a box with 24 markers = $14
(10, 7)(24, 14)
Using linear equation
Slope intercept formy = mx + bwhere
m = slope
b = y-intercept
Therefore,
m = 14 - 7 / 24 - 10
m = 7 / 14
m = 1 / 2
Therefore, let's find b
7 = 1 / 2(10) + b
7 - 5 = b
b = 2
Therefore, the linear equation where y is the price of the number of markers x is as follows:
y = 1 / 2 x + 2learn more on equation here:https://brainly.com/question/12043800
Answer:
y = 1/2x+2
Step-by-step explanation:
We have two points ( 10,7) and (24,14)
We need to determine the slope using the slope formula
m = ( y2-y1)/(x2-x1)
= ( 14-7)/(24-10)
= 7/14
= 1/2
The slope is 1/2
The slope formula is y=mx+b where m is the slope and b is the y intecept
y = 1/2x+b
Using one of the points
7 = 1/2 (10)+b
7 = 5+b
7 -5 =b
2=b
y = 1/2x+2
Laila pours some rice into a pan to cook for supper. For every 1 cup of uncooked rice, she needs to use 2 cups of water. Which equation could be used to find the amount of water, w, she should use to cook r cups of rice?
Answer: w=2r
Step-by-step explanation:
so let say the amount of water is y instead of w and the cup of rice is x instead of r.
so if we were to create a table we use the numbers given
x y
