Answer:
∠A = 115°
∠B = 65°
∠C = 115°
∠D = 65°
Step-by-step explanation:
The figure given is of parallelogram.
We need to find measure of each interior angle.
We are given:
∠A = (2x-15)°
∠B = x°
∠C = (2x-15)°
∠D = x°
We need to find measure of ∠A , ∠B, ∠C, ∠D
We know that sum of all angles of parallelogram = 360°
So, we can write: ∠A +∠B+ ∠C+ ∠D = 360°
Now putting their values and finding value of x first:
[tex]2x-15+x+2x-15+x=360\\Combining\:like\:terms:\\2x+x+2x+x-15-15=360\\6x-30=360\\6x=360+30\\6x=390\\x=\frac{390}{6}\\x=65[/tex]
So, we get x= 65
Now finding measure of each angle:
∠A = (2x-15)° = 2(65)-15 = 130-15 = 115°
∠B = x° = 65°
∠C = (2x-15)° = 2(65)-15 = 130-15 = 115°
∠D = x°= 65°
Answer is:
∠A = 115°
∠B = 65°
∠C = 115°
∠D = 65°
A 7-pack of tickets to the zoo costs $78.61. What is the unit price?
Answer:
$11.23
Step-by-step explanation:
To find the unit price divide the price by the product. For example, 12 ounces of juice costs $2.45. You divide $2.45 by 12 ounces. The unit price would be $0.20.
I hope this helped you, if it did more than all the other answers that may be on your question, feel free to give me brainliest, I would really appreciate it.
A 7-pack of tickets to the zoo costs $78.61. Therefore, the unit price of ticket to the zoo $11.23.
What is division?The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into same number of parts.
Given that a 7-pack of tickets to the zoo costs $78.61.
To find the unit price;
Cost of one pack of ticket to the zoo = total cost of 7 pack of tickets / number of tickets
Cost of one pack of ticket to the zoo = $78.61 / 7
Cost of one pack of ticket to the zoo = $11.23
Therefore, the unit price of ticket to the zoo $11.23.

if a car travels 120 miles in 4 hours. what is its speed per hour
Answer:
v = 30 km/h
Step-by-step explanation:
Given that,
Distance covered by a car, d = 120 miles
Time, t = 4 hours
We need to find the speed of the car. The speed of an object is equal to the distance covered divided by the time taken. It can be given by :
[tex]v=\dfrac{d}{t}\\\\v=\dfrac{120\ \text{miles}}{4\ \text{hour}}\\\\v=30\ \text{mph}[/tex]
So, the speed of the car is 30 km/h.

Write the equation that represents the situation then determine the cost of 5 cans of coffee: A supermarket sells 2 cans of ground coffee for$18.50. The cost of coffee varies directly with the number of cans.
Answer:
The equation is;
C = kg
c is the cost in $
k is the proportionality constant $/can
g is the number of cans
cost of 5 cans of coffee is $46.25
Step-by-step explanation:
From the question, 2 cans of ground coffee costs $18.50
Let c be the cost and g be the number of ground coffee
18.50 = k * 2
where k is the constant of proportionality;
k = 18.5/2
k = 9.25
So, the cost of 5 coffee cans will be;
c = 9.25 * 5 = $46.25

A product promoter will be working a booth at the county fair. The worker will be paid $30 for the day and an additional $2 for every person they get to sign up for a trial of their product. Write an equation that models the situation. Y represents the total amount of money earned for a day. X represents the number of people signed up for a trial of the product.
Need the answer soon!
What would the Equation be.
Answer:
I believe it is Y=30+2x
Step-by-step explanation:
Since the $30 is given no matter what, we can use it as b.
Since slope always changes, we use it as our m.
X= amount of people
2= charge per person
If there were 5 people there, the equation would look like this: y= $2(5)+$30
The dollar signs are just an aid.
Answer:
Y=2x+30
Step-by-step explanation:
The b is 30
While the slope is 2
Using y=mx+b that will be your answer.

did i get this question right?? please help me omg :((
Answer:
the answer is C because it's the only one that doesn't have any repeating x-values or repeating y-values.
D is incorrect because it's saying that no matter what the x-value is, the y-value will come out to be 6. that isn't a function
a function is when every x-value produces it's own y-value when plugged into the equation
