Answer:
x = 10°, y = 20°
Step-by-step explanation:
Fill in the missing angle measures, 20° and 70°.
7x = 180 - 90 - 20
7x = 70
x = 10
2y = 180 - 7x - 5x - 20 = 40
y = 20
Y=20
Explanation-you would take 20+90 then subtract that from 180 which gives you 70 and 7x10 is equal to 70. 70+110=180. If x=10 then 5x would give you 50, then you add 20 and get 70. Then you add another 70 because the angle between the green line and black line is equal to 7x. This would give you 140. So 2y would have to be 2(20) which give you the remaining 40.

Q1: In the isosceles triangle below the legs are twice the
length of the base. The perimeter is 100 cm. What are the
dimensions of the isosceles triangle?
Answers
Answer:
The base of the triangle has a size of 20 cm, while each side has a size of 40 cm.
Step-by-step explanation:
An isosceles triangle is one that has two sides with an identical value, and one side with a different value from the previous ones. Thus, in the case the base will have a different value from the sides. In this regard, the perimeter (the sum of the sides) of the triangle is 100 cm, and the longest sides are twice the size of the base. Therefore, to determine the value of each side of the triangle, the following calculation must be performed:
X + 2X + 2X = 100
5X = 100
X = 100/5
X = 20
Thus, the base of the triangle has a size of 20 cm, while each side has a size of 40 cm.

Answers
Answer:
x = - 11 ; m∠B = 132°
Step-by-step explanation:
(33 - 9x)° + 48° = 180°
33 - 9x + 48 = 180
81 - 9x = 180
- 9x = 99
x = - 11
m∠B = [33 - 9(- 11)]° = (33 + 99)° = 132°
m∠B = 132°

A person places $85800 in an investment account earning an annual rate of 8.5%,
compounded continuously. Using the formula V = Pert, where V is the value of the
account int years, P is the principal initially invested, e is the base of a natural
logarithm, and r is the rate of interest, determine the amount of money, to the nearest
cent, in the account after 9 years.
Answers
Answer:
$184383.7
Step-by-step explanation:
We are given that
Principal, P=$85800
Rate of interest, r=8.5%=0.085
Time, t=9 years
We have to find the amount of money after 9 years
[tex]V=Pe^{rt}[/tex]
Using the formula
[tex]V=85800e^{0.085\times 9}[/tex]
[tex]V=184383.7[/tex]
Hence, the amount of money after 9 years=$184383.7

Two chemical plants, one at Macon and one at Jonestown, produce two types of fertilizer, low phosphorus (LP) and high phosphorus (HP). At each plant, the fertilizer is produced in a single production run, so the two types are produced in fixed proportions. The Macon plant produces 1 ton of LP and 3 tons of HP in a single operation, and it charges $600 for what is produced in one operation, whereas one operation of the Jonestown plant produces 1 ton of LP and 1 ton of HP, and it charges $1,000 for what it produces in one operation. If a customer needs at least 100 tons of LP and 180 tons of HP, how many production runs from each plant should be ordered to minimize the cost.

In 1990, the cost of tuition at a large Midwestern university was $99 per credit hour. In 2003, tuition had risen to $268 per credit hour
Answers
Answer:
63%
Step-by-step explanation:
From the question, we aim to find the percent increase in the tuition
Given data
initial cost= $99 per credit hour
Final cost= $268 per credit hour
% increase= (Final - initial )/initial *100
substitute
% increase= (268- 99 )/268 *100
% increase= 169 /268 *100
% increase= 0.630*100
% increase= 63%
Hence the increase in the tuition from 1990 to 2003 is 63%

A total of 328 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold was three times the
number of adult tickets sold. How many adult tickets were sold?
Answers
Answer:
246 adult tickets were sold
Step-by-step explanation:
System of equations:
Variables:
x = number of adult tickets sold
y = number of student tickets sold
There were a total of 328 tickets sold, thus:
x + y = 328
The number of student tickets sold was three times the number of adult tickets sold, thus:
y = 3x
Substituting in the first equation:
x + 3x = 328
Simplifying:
4x = 328
Dividing by 4:
x = 328/4
x = 82
y = 3*82= 246
246 adult tickets were sold
