Answer: the answer is x+8= 1
Find the missing angle
Answer:
Step-by-step explanation:
2x + 3x = 90
5x = 90
Divide both sides by 5
x = 90/5
x = 18
Angles are: 3x = 3*18 = 54°
2x = 2*18 = 36°
11. Suppose ∆ ≅ ∆. Which choice below shows corresponding parts to congruent triangles that are
congruent? Explain your answer.
Answer:
CStep-by-step explanation:
Cross out B and D, because angle D does not correspond with Y and Angle F does not correspond with X (order matters).
It comes down to either A or C, so look at the sides.
DF does not correspond to XY, again, the order it is displayed matters.
D is the first letter and F is the last, while X is the 2nd letter of the triangle, while it should be the first letter to correspond with D
Thus by Process of Elimination the answer is C.
(Also DF DOES correspond with WY)

Write an equation modeling the change in elevation c after s seconds.
Answer:
c=-2.5s
Step-by-step explanation:
The equation modeling the change in elevation c after s seconds is
c = -2.5s
Given,
A mountain climber descends a cliff at a rate of 2.5 ft/second.
We need to write an equation modeling the change in elevation c after s seconds.
How do we represent elevation and descent?Elevation means going up so we take it as a positive distance.
Descent means going down so we take it as a negative distance.
Find the rate at which the climber descents.
2.5 ft = 1 second
Find the equation that represents the descents c in seconds.
We have,
2.5 ft = 1 second
So,
s x 2.5 ft = s x 1 seconds
2.5 s ft = s seconds
This means,
In s seconds we will have a 2.5s distance descended.
We can write this as an equation:
c = change in elevation
c = - 2.5s
Thus the equation modeling the change in elevation c after s seconds is
c = -2.5s

) Lori and Jayden open 6 packs of baseball cards. They have 72 cards in all.
They want to know how many cards, c, were in each pack.
Answer:
12
Step-by-step explanation:
Since there are 6 packs in all, and a total of 72 cards, we can multiply 6×12=72
There were 12 cards in each pack if they have 72 cards in all.
What is a numerical expression?A numerical expression is algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.
Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
Lori and Jayden crack open six packs of baseball cards. They have a total of 72 cards.
As per the given question, the required solution would be as;
Lori and Jayden have 6 packs × c cards/pack = cards in total.
This means that there are c = 72 cards / 6 packs = 12 cards in each pack.

There are a number of ways to do this type of problem. One way is to divide the figure as shown in the diagram below. See the attached image.
I'm splitting the irregular shape into two rectangles and a triangle.
The upper rectangle is 10 miles by 9 miles to get an area of 10*9 = 90 square miles. Let A = 90 so we can use it later.
The lower rectangle is 4 miles by 19 miles. Its area is 4*19 = 76 square miles. Let B = 76.
The total vertical height of the figure is 9+4+10 = 23 miles.
Notice along the column that has "8 miles" up top over "9 miles" down below, we have a gap of some distance which I'll call x. This x adds to 8 and 9 to get the 23 mentioned.
x+8+9 = 23
x+17 = 23
x = 23-17
x = 6
This helps find the height of the triangle which is 9+x = 9+6 = 15 miles.
The triangle has a base of 9 miles.
The area of the triangle is base*height/2 = 9*15/2 = 135/2 = 67.5 square miles. Let C = 67.5
--------------
We found that:
A = 90 = area of the upper rectangleB = 76 = area of the lower rectangleC = 67.5 = area of the triangleThe total area is: A+B+C = 90+76+67.5 = 233.5 square miles.

A basket of goods and services is used to calculate CPI. Assume that the basket contains 5 toothbrushes and 2 tubes of toothpaste. The prices for those goods are shown in the table.
Year Toothbrush Tube of Toothpaste
year 1 $1.00 each $2.00 each
year 2 $1.25 each $2.10 each
What will the CPI for year 2 be?
A.
9.00
B.
10.45
C.
86.00
D.
116.11
The Consumer Price Index for the year 2 be 116.11.
How do we calculate Consumer Price Index?This is calculated by adding together a sampling of product prices from a previous year.
We then add together the current prices of the same products and divide the total of current prices by the old prices, then multiply the result by 100.
Given data
Year 1 = $9
Year 2 = $10.45
Year 2 / Year 1 = $10.45 / $9.00
Year 2 / Year 1= 1.6111
CPI for year 2 = 1.61 x 100
CPI for year 2 = 116.11
Therefore, the Option D is correct.

What are the values of the variables in the triangle below?
Answer:
x=9
y=3√3
Use trig ratios
Answer:
x = 3sqr3, y = 9
Step-by-step explanation:
Use SOH CAH TOA, to solve this.
Here I know the hypotenuse, so I could use either SOH either CAH or both to find the 2 unknowns.
To find y, I would use SOH, which is Sin(angle) = opposite/hypotenuse.
When I rearrange it, I get Sin(angle)*hypotenuse = opposite. Now let's fill in with the values to give:
Sin(30)*6sqr3 = 3sqr3
And then to find x, let's use CAH, which is Cos(angle) = adjacent/hypotenuse.
Rearrange it to get Cos(angle)*hypotenuse = adjacent. This gives us a side x with a value of:
Cos(30)*6sqr3 = 9

c^{2} = b^{2} +a^{2}
use a right triangle
Answer:
9.2 m
Step-by-step explanation:
The right triangle model is shown in the attachment. The lengths 6 m and 7 m are the legs of the triangle, and the requested distance is the hypotenuse. The given Pythagorean theorem equation can be used to find the desired distance:
c² = a² +b²
c² = 7² +6² = 49 +36 = 85
c = √85 ≈ 9.2
Gabe and Adele are about 9.2 meters apart.

If you can also tell me what "employment-to-population ratio" is, what "labor force participation rate" is, "unemployment rate" all using the values of the table, i will make you brainiest.
Answer:
Total Population = Young & Institutionalized + Working Age Population
Working-Age Population = Labor Force + Not in the Labor Force
Labor Force = Employed + Unemployed
Total population = 400
Working Age Population = 300
Young & Institutionalized = 100
Not in Labor Force = 100
Labor Force = 200
Employed = 150
Unemployed = 50
Employment-population ratio = (Employed ÷ Working Age Population) x 100%
= (150 ÷ 300) × 100%
= 50%
Labor force participation rate = (Labor Force ÷ Working Age Population) x 100%
= (200 ÷ 300) × 100%
= 66.7% (nearest tenth)
Unemployment rate = (Unemployed ÷ Labor Force) x 100%
= (50 ÷ 200) x 100%
= 25%

I bought x cans of fruit cocktail and two more cans of mushrooms than cans of fruit cocktail. A can of mushrooms cost $.80 and a can of fruit cocktail cost $.90. How much money did I spend?
Answer:
0.9x + 0.8(x + 2)
Step-by-step explanation:
# of cans of fruit cocktail: x
# of cans of mushrooms: 2 more than x, or x + 2
$ of can of mushroom: $0.80
$ of can of fruit cocktail: $0.90
To find out how much money you spent, you need to multiply the # of cans by their respective prices. Therefore:
The price of the cans of fruit cocktail = 0.90 * x
= 0.9x
The price of the cans of mushrooms = 0.80 * (x + 2)
= 0.8(x + 2)
Total price = 0.9x + 0.8(x + 2)
