I hope this helps
Step-by-step explanation:
So the way to handle a problem like this is to rewrite the three numbers in terms of their relationship to one of the three numbers. Let's call the numbers x, y, and z, where x is the first number, y is the second, and z is the third.
We know x + y + z = 83.
Since the third number is twice the second, we say that z = 2y.
Since the second number is seven less than the first, we say that y = x - 7. We can rewrite this as x = y + 7.
Now all three can be written in terms of y.
x + y + z = 83
(y + 7) + y + 2y = 83
4y + 7 = 83
4y = 76
y = 19
The second number is 19. The first is 19 + 7 or 26, and the third is 2 times 19 or 38.
A check reveals that 26 + 19 + 38 = 83.
The average value of a function f on [a, b]
always lies between f(a) and f(b). Justify your answer.
Answer:
False
Step-by-step explanation:
A parabola is a good example of proving this false, but more specifically is the graph of sin x on the interval [0, pi]. sin 0 = sin pi = 0, but the average value of sin x on this interval is greater than 0.
The average value of a function f on [a, b] always lies between f(a) and f(b) is false.
What is a function?A relation is a function if it has only One y-value for each x-value.
The average value of a function over an interval [a,b] is the total area over the length of the interval
A parabola is a good example of proving this false, but more specifically is the graph of sin x on the interval [0, pi].
sin 0 = sin pi = 0, but the average value of sin x on this interval is greater than 0.
So the average value of a function f on [a, b] always lies between f(a) and f(b) is false.
Hence, the average value of a function f on [a, b] always lies between f(a) and f(b) is false.

Answer:
5/8+1/3=6/11
first u add the fraction and u get the answer of 6/11.
Answer:
7/24
Step-by-step explanation:
5/8 = 15/24
1/3 = 8/24
15/24-8/24 = 7/24
The question was what fraction of all the songs are jazz. Therefore you need to find the common denominator which is 24. (8x3 =24).
Next you Multiply 5x3 which equals 15 and then you multiply 1x8 which equals 8. (We do this because you need to multiply your numerator by the same number you multiplied your denominator with)
Finally, you subtract 8/24 from 15/24 which equals 7. (15-8=7 [make sure you keep your denominator 24] )
Therefore your answer is 7/24
At a sale, coats were sold for 52% of their original price. If the coats originally cost
$200 each, how much did a coat cost on sale?
Help me please
Answer:
Answer is 104
Step-by-step explanation:
The selling price of the coat is $104.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Original price = $200
Selling price.
= 52% of $200
= 52/100 x 200
= $104
Thus,
$104 is the selling price of the coat.

Answer:
I am not sure but for
CAE it is 65˚
CBD it is 65˚
Step-by-step explanation:
x+40=3x-10
Move the 3x to the other side by subtracting by 3x on both sides
x-3x+40=3x-3x-10
The equation now looks like this:
-2x+40=-10
Move 40 to the other side by subtracting 40 both sides:
-2x+40-40=-10-40
-2x=-50
Divide by -2 on both sides:
-2x/-2=-50/-2
x=25
Since we found out what x is we can replace x in both CAE and CBD:
For CBD: 25+40 is 65
For CAE: 3(25)-10 is 65
Answer:
m∠CAE = 65, m∠CBD = 65
Step-by-step explanation:
Line CA is a transversal of lines AE and BD which are parallel, in this case corresponding angles are congruent. ∠CAE and ∠CBD are corresponding angles so you can make them equal to each other. x+40=3x-10 -> 2x=50 ->x=25. Now that we have x just plug it into the equations 25+40=65 which is m∠CBD. 3(25)-10=75-10=65 is m∠CAE
A recipe for sparkling grape jucie calle for 1 1/2 quarts of sparkling water and 3/4 quart of grape jucie. How much sparkling water would you need to mix with 9 quarts of grape jucie?
Answer: 18 quarts of sparkling water
Step-by-step explanation:
From the question, we are informed that a recipe for sparkling grape jucie calle for 1 1/2 quarts of sparkling water and 3/4 quart of grape jucie.
When there's an increase in the quarts of grape juice to 9, it simply means that the former grape juice has been multiplied 12 times (9 ÷ 3/4 = 9 × 4/3 = 12).
Therefore, we would also multiplybl the sparkling water given by 12 to get the new quantity needed. This will be:
= 1 1/2 × 12
= 3/2 × 12
= 18 quarts of sparkling water

I like this better without fractions, so would multiply by 16 at this point (or earlier).
x^2 -40x +144 = 0
(x -36)(x -4) = 0
x = 4 or 36 . . . . . . x = 4 is extraneous
The solution is x = 36.

Answer:
885.45
Step-by-step explanation:
Testuo monthly payments will be around 885$
What is InterestIt is a fee paid for borrowing money or other assets.
• the amount borrowed is called the principal.
• the interest is expressed as a percentage rate of the principal
for a given time interval.
It is given that
Value of the car = $32000
Time period of loan repayment = 36 months
T = 3 years
Rate of Interest = 6.71%
10% down amount from 32000 = 3200 $
So the amount he is putting for finance = 32000 - (0.1 × 32000)
= $28800
Rate of interest can be calculated from
I = P x R x T
I = Interest, P = Principle, R = Rate, T = Time
= (6.71 * 28800 * 3)/(100*12)
= $ 483.12
This is total interest for an year
In one month, rate of interest
= 483.12/12
= $40.26
The principal amount that will be payable per month
= 28800/36
= $800
Total amount payable will be
= $ ( 800 + 40.26 )
= $840
Hence, we can conclude, Tetsuo needs to pay $840.26 as monthly installments, so in the options given it is 885$

Which equation would best help solve the following problem? The height of a triangle is 5 m less than its base. The area of the triangle is 42 m² What is the length of the base?
Answer:
[tex]\boxed{\displaystyle 42=\frac{1}{2}x(x-5)}[/tex]
The second choice is correct
Step-by-step explanation:
Area of a Triangle
Given a triangle of base B and height H, the area is calculated by the formula:
[tex]\displaystyle A=\frac{1}{2}BH[/tex]
Let's call x=base of a triangle
Since the height of the triangle is 5 m less than the base:
x - 5 = height of the triangle.
Thus, the area is
[tex]\displaystyle A=\frac{1}{2}x(x-5)[/tex]
The value of the area is given as A=42 square meters, thus:
[tex]\boxed{\displaystyle 42=\frac{1}{2}x(x-5)}[/tex]
The second choice is correct
