Answer:
$12.78.
Step-by-step explanation:
To determine the expected price of a good in 2000, knowing that in 2015 it cost $ 17.6 and that the consumer price indexes were worth 172.2 in 2000 and 237.017 in 2015, the following calculation must be performed:
237.037 = 17.6
172.2 = X
X = 172.2 x 17.6 / 237.037
X = 3,030.72 / 237.037
X = 12.78
Thus, the expected price of the good in the year 2000 is $ 12.78.

What is BD? please help bru i keep getting trollers
Answer:
BD=13
(This must not be drawn to scale)
Step-by-step explanation:
You have to use the Angle Bisector Theorem to get a ratio.
12/x=27/(x+5)
cross multiply
12(x+5)=27x
12x+60=27x
60=27x-12x
60=15x
60÷15=x
x=4
BD=x+x+5=4+4+5=13
pls make sure ur answer is correct

In 1985, there were 20 students
In 2005, there were 45 students
This is a change of 45-20 = 25 students.
This amount of change is divided by the original amount 20 to get 25/20 = 1.25 and converts to 125% when you move the decimal point 2 spots to the right.
-------------
If you want, you can use the formula below
x = old value = 20
y = new value = 45
z = percent change
z = [ (y-x)/x ] * 100%
z = [ (45-20)/20 ] * 100%
z = (25/20) * 100%
z = 1.25*100%
z = 125%
The z value being positive means we have a percent increase.
It's possible to have over 100% increase since 100% of 20 is 20. Having a 100% increase means we increased by 20. Since we increased by more than 20, this means the increase must be over 100%.
Solve the equation -10(d+1)=-14 I ready, please help ASAP!!
Answer:
d = 0.4
Step-by-step explanation:
-10 (d + 1) = - 14
=> -10d - 10 = -14
=> -10d = -14 + 10
=> -10d = -4
=> 10d = 4
=> d = 4 / 10
=> d = 0.4
Hope it helps :)

Answer:
adjust city gallons to 3 gallons and freeway to 7 gallons
make your line in the chart:
3 | 10-3 = 7 | 3(25) = 75 | 7(40) = 280 | 75 =280 =355 | 355 | yes
Step-by-step explanation:
x = city gallons
y = freeway gallons
x+y = 10 then y = 10-x
25x+40y = 355
substitute for y
25x+40(10-x) = 355
25x+400-40x = 355
-15x+400 = 355
subtract 400 from each side
-15x = -45
divide both sides by -15
-15x/-15 = -45/-15
x = 3 gallons
y = 7 gallons

Answer and Step-by-step explanation:
Let's solve your equation step-by-step.
−2(x+5)=4
Step 1: Simplify both sides of the equation.
−2(x+5)=4
(−2)(x)+(−2)(5)=4(Distribute)
−2x+−10=4
−2x−10=4
Step 2: Add 10 to both sides.
−2x−10+10=4+10
−2x=14
Step 3: Divide both sides by -2.
-2x/2 = 14/-2
x equals...

There are formulas to solve cubics, but that probably is not the way you are expected to go. Here is a trial and error approach that works in this case.
Assume that the cubic can be factored and that the roots are r1, r2, and r3. Then the factored form is
(x-r1)(x-r2)(x-r3)=0
This shows that the constant must equal the product of the roots.
(r1)(r2)(r3)=-33
One possibility is that the roots are integers. In this case, a factor of 33 might work. Prime factorization of 33 gives 3 and 11. Try 3. Then (x-3) is a factor.
Divide the cubic by (x-3). It works. the result is
x^2+12x+11
This has factors of (x+11) and (x+1). Therefore, the roots are 3, -1, and -11
Write an expression to show k less than 10
Step-by-step explanation:
"Write an expression to show k less than 10"
"less than" means that the number is being subtracted from a different number.
This means that "10" is being subtracted from "k"
Thus,
k - 10 is the appropriate expression for the statement, "k less than 10"
ANSWER: k - 10

the distance between two cities on a map is 3.5 centimeters. The map uses a scale in which 1 centimeter reprecents 20 kilometers. what is the actual distance between these two cities in kilometers?
Answer:
70 kilometers
Step-by-step explanation:
Set up a proportion where x is the actual distance
[tex]\frac{1}{20}[/tex] = [tex]\frac{3.5}{x}[/tex]
Cross multiply:
x = (20)(3.5)
x = 70
So, the actual distance is 70 km
find the value 4/25 1/2
Answer:
2/5
Step-by-step explanation:
we know any number raised to power 1/2 means that we need to find the square root of that number.
(4/25)^1/2= =√(4/25)√4/√25
√4=2
√25=5
√(4/25=2/5

A side of the triangle below has been extended to form an exterior angle of 128° . Find the value of x.
Answer:
Step-by-step explanation:
The sum of adjacent angles traversed by a line must equal 180 degrees.
128+x=180
x=52
Answer:
x=52 degrees
Step-by-step explanation:
x=180-128=52 degrees because x is supplementary to 128 degrees.

One number is five less than another. Their sum is fifteen. Find the numbers.
Answer:
THE NUMBERS ARE 10 AND 5
Step-by-step explanation:
LET THE ANOTHER NUMBER BE X THEN
ONE NUMBER = X - 5
BY THE QUESTION
X - 5 + X = 15
2X = 15 + 5
2X = 20
X = 10
X - 5 = 10 - 5 = 5
Answer:
hi 5 and 10 is required no.
let no. be x
another no.be x+5
Step-by-step explanation:
sum=15
x+x+5=15
2x=15-5
2x=10
x=10/2=5
x+5=5+5=10

Dan invests £18790 into his bank account. He receives 5,3% per year simple
interest. How much will Dan have after 7 years? Give your answer to the nearest
penny where appropriate,
Answer:
697109 pennies
Step-by-step explanation:
First, you use the formula A = P (1 + rt).
R= rate which is 5.3%
T= time which is 7 years.
P is the principle which is 18790
A= is the answer
so first you multiply 7*5.3% which you get 0.371
then you multiply that with 18790 which then you get 6971.09
if you want pennies you multiply it with 100 to get 697109
What will be the area of this parallelogram?
Include the appropriate unit in your answer.
Answer:
13.75 square feet
Step-by-step explanation:
all you have to do to find the area of a parallelogram is base * height
= 2.5 * 5.5
= 13.75 square feet
Answer:
13.75 ft^2
Step-by-step explanation:
I) Substitute equation to find the area
a = hb (area = height x base)
a = 2.5(5.5)
II) Solve:
a = 2.5(5.5)
a = 13.75
The area is 13.75 ft^2.

The net of a rectangular prism and its dimensions are shown in the
diagram.What is the total surface area of the rectangular prism in square
inches?
PLEASE
Answer:
286.5 in.²
Step-by-step explanation:
The surface area of the prism = sum of the area of each surface
= (7.5*3) + (11.5*3) + (7.5*3) + (11.5*3) + (11.5*7.5) + (11.5*7.5)
= 22.5 + 34.5 + 22.5 + 34.5 + 86.25 + 86.25
Surface area = 286.5 in.²

Describe the sequence of transformations that shows a quadrilateral of rstu is similar to quadrilateral VXYZ
Answer: What does the figure look like exactly?
Step-by-step explanation:
A gas station sells 1600 gallons of gasoline per hour if it charges $ 2.70 per gallon but only 900 gallons per hour if it charges $ 2.95
per gallon. Assuming a linear model
(a) How many gallons would be sold per hour of the price is $ 2.90 per gallon?
Answer:
(b) What must the gasoline price be in order to sell 1300 gallons per hour?
Answer:
Answer:
Look just at finding the linear model. Two points. Use price per gallon for x and gallons per hour sold for y. Your two points (x,y) are (2.15,1600) and (2.55,800).
Slope m=%281600-800%29%2F%280.15-0.55%29
m=800%2F0.40
m=2000
Using point-slope form for a line, and the lower-y point,
y-800=2000%28x-2.55%29
highlight%28y=2000%28x-2.55%29%2B800%29
answer and show work and ill give brainliest, Steven has one bag that contains three table-tennis balls numbered 1, 2, and 3. He also has a second bag that contains four table-tennis balls lettered A, B, C, and D.
Answer:
B
Step-by-step explanation:
Assuming Part A is the situation where the bags aren't merged, the probability of drawing a "1" followed by a "B" is (1/3)(1/4) or 1/12. This is because you have a 1/3 chance of getting a "1" and a 1/4 chance of getting a "B".
Now if we merge the bags, we have a 1/7 chance of getting a "1". We then have a 1/6 chance of getting a "B". This is because after we complete the first draw, the bag only has 6 remaining not 7. This gives us a probability of (1/7)(1/6) or 1/42.
So we know the probability will change so C is wrong. In both scenarios, we draw two balls anyways so A is wrong.
This leaves B, which is supported by the reasoning presented above.

Answer:
$76.32
Step-by-step explanation:
First, add up all the costs for everything:
17 + 30 + 25 = 72
Now, we need to add the sales tax. To do this we multiply 72 by 1.06. This is because the sales tax is 6% (the decimal form of 6% is 0.06), and we add it on to the 100% cost (which is 1 in decimal form).
(72)(1.06) = 76.32
Therefore the total cost of everything Walter bought plus the tax rate is $76.32.
