Answer:
y = 4
Step-by-step explanation:
In this situation, because all the angles have the same arc mark, they must have the same measure which means that the triangle is equiangular. Therefore, you can use the definition of an equilateral triangle which states that if the triangle is equiangular, it must be equilateral which means that all sides are the same. This is because x + x + x = 180 → 3x = 180 → x = 60. When you learn trigonometry, you will realize that the proportion of sides corresponds to the angles. Or you could experiment and you may realise that if the angles of the triangles are all 60° then you can only form a triangle where the sides are all equal. If all sides are the same, then 9y - 3 = 7y + 5
So if 9y - 3 = 7y + 5, then
9y - 3 = 7y + 5 →
[subtract 7y from both sides]
9y - 7y - 3 = 7y - 7y + 5 →
2y - 3 = 5 →
[add 3 to both sides]
2y - 3 + 3 → 5 + 3 → 2y = 8 →
[divide both sides by 2]

the sum of length and breadth of a room is 20m,find it's perimeter
Answer:
80 m.
Steps: perimeter =4 x side
=4x20=80m
Answer:
40 m
Step-by-step explanation:
Formula of perimeter of a rectangle = 2(l + b)
where l = Length & b = Breadth
According to the question ,
Sum of length & breadth = l + b = 20m
Perimeter = 2(l + b) = 2 × 20 = 40m

Answer: x = 4
Step-by-step explanation:
JL = 2 (MN)
3x - 2 = 2 (x + 1)
3x - 2 = 2x + 2
Subtract 2x from both sides
x - 2 = 2
Add 2 to both sides
x = 4

2. angle ABE = angle MNP
Write another valid congruency statement:
Given:
[tex]\Delta ABE\cong \Delta MNP[/tex]
To find:
The congruent angles and sides, then find the another valid congruency statement.
Solution:
We have,
[tex]\Delta ABE\cong \Delta MNP[/tex]
We know that, corresponding parts of congruent triangles are congruent (CPCTC).
Using CPCTC, we get
Angles:
[tex]\angle A\cong \angle M[/tex]
[tex]\angle B\cong \angle N[/tex]
[tex]\angle E\cong \angle P[/tex]
Sides:
[tex]AB\cong MN[/tex]
[tex]BE\cong NP[/tex]
[tex]AE\cong MP[/tex]
The another congruent statement is [tex]\Delta BEA\cong \Delta NPM[/tex].
Therefore, the required table is
Angles Sides
[tex]\angle A\cong \angle M[/tex] [tex]AB\cong MN[/tex]
[tex]\angle B\cong \angle N[/tex] [tex]BE\cong NP[/tex]
[tex]\angle E\cong \angle P[/tex] [tex]AE\cong MP[/tex]
The another congruent statement is [tex]\Delta BEA\cong \Delta NPM[/tex].
In kite WXYZ, mZWY = 41° and mXYW = 11°
What is mWZY?
Answer:
128°
Step-by-step explanation:
In kite WXYZ, WY and XZ are longer and smaller diagonals respectively.
Longer diagonal bisects the opposite angles.
[tex] \therefore m\angle ZYW =m\angle XYW[/tex]
[tex] \because m\angle XYW = 11\degree... (given) [/tex]
[tex] \therefore m\angle ZYW =11\degree [/tex]
[tex] In\: \triangle WYZ[/tex]
[tex] m\angle ZYW + m\angle ZWY + m\angle WZY=180\degree [/tex]
[tex] 11\degree + 41\degree+ m\angle WZY=180\degree [/tex]
[tex] 52\degree+ m\angle WZY=180\degree [/tex]
[tex] m\angle WZY=180\degree - 52\degree [/tex]
[tex] \purple{\bold {m\angle WZY=128\degree}} [/tex]
John jogged 4.5 miles on Thursday, 7 2/5 miles on Friday, and 10.4 miles on Saturday. How many miles does John have to run in order to run 25 miles for the week
im giving 20 points
Answer:
2.7 miles
Step-by-step explanation:
25 - 10.4 - 4.5 - 7 2/5 will give you 2.7
Answer:
8 miles
Step-by-step explanation:
If we divide 70 by 50, we get the unit rate for the ratio 70 minutes for every 50 miles.
70÷50=1.4
So the runner is running 1.4 minutes per mile. We can multiply this unit rate by the number of miles:
1.4 minutes mile × 5 miles = 7 minutes
Thus it will take her 7 minutes to run 5 miles at this pace.
If it takes her 7 minutes to run 5 miles, it will take her 7÷5 = 1.4 minutes to run 6÷3=2 miles at the same pace.
If it takes her 1.4 minutes to run 5 miles, it will take her 1.4×5=7 minutes to run 4×2=8 miles at the same pace. Since 60 minutes is 1 hour, she is running at a speed of 8 miles per hour.
We found her pace in minutes per miles in part (a).

Which graph shows a dilation?
Answer:
the last one shows a dialation
Find the slope of the line represented by the data below
Answer:
Slope = -4
Step-by-step explanation:
Let us solve the question
∵ The slope of the line is m = Δy/Δx
∵ Δy is the change of y ⇒ Δy = y2 - y1
∵ Δx is the change of x ⇒ Δx = x2 - x1
→ Choose from the table x1, y1 and x2, y2
∵ x1 = -3 and y1 = 12
∵ x2 = -2 and y2 = 8
→ Use them to find Δx and Δy
∵ Δx = -2 - (-3) = -2 + 3 = 1
∴ Δx = 1
∵ Δy = 8 - 12 = -4
∴ Δy = -4
→ Use them to find the slope
∵ m = Δy/Δx
∴ m = [tex]\frac{-4}{1}[/tex]
∴ m = -4
∵ m is the slope of the line
∴ The slope of the line is -4

Solve the equation | w + 1.5 = 8.75
Answer:
8.75-1.5=7.25
w=7.25
Step-by-step explanation:
Answer:
w = 7.25
Step-by-step explanation:
w + 1.5 = 8.75
To find what w is, you need to isolate. To isolate w from 1.5, you have to subtract 1.5 by 1.5.
w + 1.5-1.5 = 8.75
What you do to one side of the equal sign, you have to do to the other
w + 1.5-1.5 = 8.75 - 1.5
1.5-1.5 cancels out and 8.75 - 1.5 equals to 7.25
w = 7.25
The value of a bank account is −$28. Money is then deposited into the account. Which could represent the value of the account now? A.-$33 B.-$6 C.-$45 D.$17 E.$0
Answer:
Step-by-step explanation:
depends how much money is deposited, however, the choices can be just D or E
Answer:
B,D,E
Step-by-step explanation:
Does it say how much was deposited? Ok so deposit means your bank gets bigger so it cannot be less than -28.
My guess is that it will be either B,D,E
The reason I say my guess is because I think the question should have given you an amount of how much was deposited.

The proportion of American adults who spend between 6 and 9.99 hours a day, inclusive, on digital devises is approximately 1/3. The proportion of Americans adults who spend more than 9.99 hours on a digital dev is approximately 2/7. Find the proportion of American adults who spend at least 6 hours on digital devices. Write your result as a fraction.
Answer: 13/21 of the American adults spend at least 6 hours on digital services.
Step-by-step explanation:
The proportion that spends between 6 hours and 9.99 hours is 1/3
The proportion that spends more than 9.99 hours is 2/7
We want to find the proportion who spends at least 6 hours.
This is easy, we just need to combine the two groups from above, and that will give use the proportion that spends 6 hours or more.
We only need to add:
1/3 + 2/7
Now, the first problem we see here is that the denominators are different, then we need to rewrite both fractions to have the same denominator.
We know that 3*7 = 21, then we can use 21 as the common denominator, by multipliying by 7/7 (this is equal to 1) the first fraction, and by 3/3 the second one:
1/3 = (1/3)*1 = (1/3)*(7/7) = 7/21
2/7 = (2/7)*1 = (2/7)*(3/3) = (3*2)/21 = 6/21
Then the previous sum becomes:
1/3 + 2/7 = 7/21 + 6/21 = 13/21
This means that 13/21 of the american adults spend at least 6 hours on digital services.
What is the slope of the line that passes through the points (8,-4) and (6,3) in simplest form
Step-by-step explanation:
Rise of y-value = (-4) - (3) = -7.
Run of x-value = (8) - (6) = 2.
Slope of the line = Rise / Run = (-7) / (2) = -3.5.

The numbers 1 through 10 are written on individual cards and placed in a bag. If you reach into the bag and pull out a cards, what is the probability that it will not be a 9
Answer:
9/10
Step-by-step explanation:
There are 10 cards in total (1-10 is 10 numbers). Only 1 of the numbers is a 9. So the probability of picking the 9 is 1/10. Then do 1 - 1/10 to find the probability of not picking the 9. This is 9/10.
