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°

x=98/1000
x=49/500
x=0.98
if it is rounded to the nearest hundredth then x=0

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.

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.

Maria is making paper flowers as decorations for the fall dance. She has made 40 flowers so far, and she is 16% finished. If she plans to finish making 70% of the total flowers needed by tonight, how many more will she need by then? Please answer soon its due 11:59 tonight!!
Answer:
the number of additional she needed is 135
Step-by-step explanation:
The computation is shown below:
GIven that
40 flowers of 16%
So for 100% it would be
= 40 ×100 ÷ 16
= 250
Now she needs to make is
= 70% - 16%
= 54%
Now the additional would be
= 250 × 54%
= 135
Hence, the number of additional she needed is 135
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
