Answer:
Z is 66. If you want an explanation, I could give it to you, FYI.
Answer:
x=66°
Step-by-step explanation:
Solve for x:
If the two vertical lines are parallel, then the given angles are same side interior angles that are supplementary angles. This means that their values add up to 180°:
∠1+∠2=180°
Substitute known values:
[tex]x+114=180[/tex]
Subtract 114 from both sides to isolate x:
[tex]x+114-114=180-114\\\\x=66[/tex]
The value of x is 66°.

What similarity property, if any, can be used to show that the following two triangles are similar.
Answer:
The angles
Step-by-step explanation:
On both triangles, there is a square in the corner which means that both angles are 90 degrees, and then on the left side of the triangle, there are two signs that are the sames meaning those two have the same angle measurement. Based on this knowledge I know that the last angle of the triangle must also be the same degrees since both triangles follow the same equation 90+a+b=180. I know that all angle measurements from one triangle must equal 180. So these are the same triangles with different sizes.

Answer:
2 apples = .24 kilograms
12 apples = 1.44 kilograms
Step-by-step explanation:
If 5 apples all weigh The same amount. Let x represent one apples weight
5x = 0.60
divide by 5
one apple weighs .12 kilograms
then multiply by the number of apples. So 2 apples is .24
and 12 apples is 1.44
Zack wants to purchase vinyl to go on his bathroom floor. The vinyl is sold by the foot in length. If the area of his bathroom is 100 square feet, what will one side of the square bathroom measure?
Answer:
x = 10 feet
Step-by-step explanation:
Given that,
The area of his bathroom is 100 square feet.
We need to find the one side of the square bathroom.
Let the side be x. The area of a square is given by :
[tex]A=x^2\\\\100=x^2\\\\x=10\ \text{feet}[/tex]
So, the side of the square bathroom is 10 feet.

Answer:
C. x=2.5, DC=7.5, EC=15
Step-by-step explanation:
since the triangles have congruent angles, the sides have a relationship too. Basically, the ratio between the triangle is 4:10 because those sides math up. So, that also means it is 2:5. Therefore, BC:EC=6:15. 15-12.5=2.5, so x=2.5.
Now you can just do 2.5+5=7.5 so DC=7.5

Avery owns a small business selling ice-cream. She knows that in the last week 6
customers paid cash, 48 customers used a debit card, and 16 customers used a credit
card.
If next week, she is expecting 400 customers, about how many would you expect to
pay with a credit card? Round your answer to the nearest whole number.
Answer:
About 91 customers would be expected to pay with a credit card.
Step-by-step explanation:
Well you have ro set up a ratio of 16/70 = x/400
This way the amount of people that used a credit card out of all of the people that came and you can figure out the amount of people that will use a credit card out of the 400 people that are expected tho come. You multiply like a butterfly. 70 times x and 400 by 16. Then you will get 6,400=70x divide both sides by 70 and get 91.42=x so if ypu round, 91 people are expected to pay using a credit card out of the 400 customers that are expected to come.

8-(8)= 0
3-(-2)= 5
since the two points have 8 in the Y space the line would be equal to y= 8
Explain why the exponents cannot be added in the product 12^3 x 11^3?? I need a simple answer that won’t be confusing pls.
Answer:
The bases aren't the same
Step-by-step explanation:
If the bases are the same, then their exponents are added. In this case, since the exponents are the same, then 12^3*11^3=(12*11)^3=132^3=2299968
Morgan is in the business of manufacturing phones. She pays a cost of $200
per phone produced for materials and labor and also must pay a daily fixed
cost of $400 to rent the building and equipment. Make a table of values and
then write an equation for C, in terms of p, representing total cost, in dollars,
of producing p phones in a given day.
Answer:
C = 200p + 400
Step-by-step explanation:
Because C is the cost of a given day, 400 acts as a y-intercept.
400 is the initial fee paid then 200 per each phone manifactured, meaning that 200 is the slope.

Answer:
AB≅AC (two legs of isosceles triangles are always equal)
6x-14 = 4x+20
2x-14 = 20
2x = 34
x = 17
Base ⇒ 7x-12
= 7(17)-12
= 119-12
= 107
Answer:
x=17, 107
Step-by-step explanation:
Since it is given that the triangle is isosceles, we can make the following equation:
6x-14=4x+20
x=17
To find the base (7x-12), all you have to do is plug in the value of x
7x-12
7*12-12
107

The formula d-2r can be used to find the distance(d) traveled after 2 hours when driving at rate r.
A. Solve the formula for r.
B. Find the rate(r) when the distance traveled is 130 miles.
Answer:
A. d/2 = r
B. r=65 miles/hour
Step-by-step explanation:
A. d/2 = 2r/2
B. Using the formula you found for R it is
130/2= r, therefore r = 65
The formula for r is:
r = d/2.
The rate r when the distance traveled is 130 miles is:
= 64 miles per hour.
Given,
The formula d = 2r can be used to find the distance(d) traveled after 2 hours when driving at rate r.
We need to:
- Solve the formula for r.
- Find the rate(r) when the distance traveled is 130 miles.
What is the formula for speed?Speed = distance / time
We can find the distance as:
distance = speed x time
We have,
d = 2r where d = distance and r = rate.
Here 2 = 2 hours
The formula for r :
d = 2r
Divide both sides by 2.
d/2 = r
r = d/2
r = distance / 2 hours
The rate at a distance of 130 miles is:
d = 130 miles
r = d / 2
r = 130 / 2 = 65 miles / hour
Thus,
The formula for r is d/2.
The rate r when the distance traveled is 130 miles is 64 miles per hour.

Un hacendado a comprado doble numero de vacas que de bueyes, por cada vaca pago 70 dólares y por cada buey 85 dólares, si el importe de la compra fueron 2,700 dólares cuantas vacas y bueyes compro
Responder:
Número de bueyes = 12
Número de vacas = 24
Explicación paso a paso:
Dado que :
Número de vacas compradas = 2 veces el número de bueyes;
Sea número de bueyes = y
Número de vacas = 2 años
Costo de la vaca = 70
Costo de bueyes = 85
Costo total = 2700
Por lo tanto;
(2 años * 70) + (y * 85) = 2700
140 años + 85 años = 2700
225 años = 2700
225 años / 225 = 2700/225
y = 12
Número de bueyes = y = 12
Número de vacas = 2y = 2 * 12 = 24
