Answer:
f(3) = 71
Step-by-step explanation:
f(x) = 10(x + 5) − 9
f(3) = 10(3 + 5) - 9
f(3) = 10(8) - 9
f(3) = 80 - 9
f(3) = 71

Answer:
#1: 1) Buying a pack of 3
#2: 2) Jim
#3: 2) 65
#4: 1) $0.04 per fluid ounce
Step-by-step explanation:
#1:
5 shirts for $26.25; divide $26.25 by 5 to get the individual shirt which is $5.25
3 shirts for $14.25; divide $14.25 by 3 to get the individual shirt which is $4.75
10 shirts for $52.25; divide $52.25 by 10 to get the individual shirt which is $5.225 ($5.23).
The cheapest individual shirt is the 3 shirt package.
#2:
Dwight: 3 tickets for $191; divide $191 by 3 to get the individual ticket cost which is $63.67 (Rounded to the nearest hundredth)
Jim: 5 tickets for $309; divide $309 by 5 to get the individual ticket cost which is $61.80
Pam: 7 tickets for $435; divide $435 by 7 to get the individual ticket cost which is $62.14 ( Rounded to the nearest hundredth
Andy: 4 tickets for $256; divide $256 by 4 to get the individual ticket cost which is $64.00
The one who paid the lowest price per ticket is Jim.
#3:
91 portraits in 7 weeks
? portraits in 5 weeks
By cross multiplying, we get 455 portraits in 7weeks*?
To find the unknown, we divide 7 by both sides, leaving the unknown by itself.
[tex]\frac{455}{7}[/tex] = ?
? = 65 portraits
#4:
2-quart bottle for $2.56
1 quart is equal to 32 ounces
Since we know that the bottle cost $2.56, we can divide the cost with the amount of ounces it needs, like the following: $2.56 divided by 64 ounces.
Why 64? The bottle of juice is 2-quarts, so we multiply 32 ounces by 2 to get 64 ounces.
The answer should be $0.04 per fluid ounce.

1/4 (y+6) + 5 = 1/3 (4y-1) -17
Answer:
y = 22
Step-by-step explanation:
1/4 (y + 6) + 5 = 1/3 (4y - 1) - 17
1/4y + 6/4 + 5 = 4/3y - 1/3 - 17
1/4y - 4/3y = - 1/3 - 17 - 6/4 - 5
3/12y - 16/12y = - 4/12 - 17 - 18/12 - 5
- 13/12y = - 22/12 - 22
- 13/12y = - 22/12 - 22/1
- 13/12y = - 22/12 - 264/12
- 13/12y = - 286/12
- y = - 286/12 / 13/12
- y = - 286/12 * 12/13
- y = - 286/1 * 1/13
- y = - 286/13
y = 286/13
y = 22
One of those fraction type questions, that I don’t know
Answer:
C
Step-by-step explanation:
To solve this problem, we need to first find the ratio of numbers less than four to total numbers.
There are 3 numbers on the wheel less than 4 (1, 2, and 3). There are 8 total numbers, meaning the ratio of numbers less than 4 to total numbers is 3:8.
Now, we need to find the probability of spinning a white number. There are 3 white numbers on the wheel (3, 5, 8). However, one of these numbers (3) is less than 4, so it is already accounted for in the previous ratio. There are 2 numbers left, meaning the ratio of remaining white numbers to total numbers is 2:8.
Adding this to the original equation, we get 5:8. As a fraction, 5:8 = 5/8. The answer that correctly highlights this is C.

A jar contains nine blue marbles, eight yellow marbles, 11 black marbles, and 12 red marbles.
Without looking, what is the probability of pulling a white marble from the jar?
1
0
3/10
9/40
Answer:
0%
Step-by-step explanation:
The first thing you need to do, is add the total of all of the marbles together.
9 + 8 + 11 + 12 = 40.
Knowing this, you can take the amount of white marbles, (0) and put this against the 40 total marbles.
Since there are 0 white marbles in the jar, you know that it is impossible to pull one out of the jar.
0%
Answer: The answer is 0, because there is 0 white marbles in the jar to begin with.

The pool above has a length of 32 feet, width of 18 feet, and depth of 6 feet. How much water can it hold?
Answer: 3456 cubic metres
Step-by-step explanation:
32 * 18 * 6 is the volume of which can be held in the pool
Answer: 3456 cubic feet
Step-by-step explanation:
Multiply the length times width times depth.
32 × 18 × 6 = 3456
Then multiply the unit measure.
Feet × feet = square feet. Ft^2
Feet × feet × feet = cubic feet. Ft^3
Raising 16 to a power that is 3 times some number is the same as raising 32 to twice the sum of the number and 2. Which exponential equation represents this situation?
Answer:
[tex]16^{3x}= 32^{2(x+2)}[/tex]exponential equation represents this situation
Step-by-step explanation:
Let the number be x
Raising 16 to a power that is 3 times some number=[tex]16^{3x}[/tex]
Raising 32 to twice the sum of the number and 2 =[tex]32^{2(x+2)}[/tex]
We are given that Raising 16 to a power that is 3 times some number is the same as raising 32 to twice the sum of the number and 2.
Equation:[tex]16^{3x}= 32^{2(x+2)}[/tex]
So, The required equation is[tex]16^{3x}= 32^{2(x+2)}[/tex]
Hence [tex]16^{3x}= 32^{2(x+2)}[/tex]exponential equation represents this situation

Answer:
hi! id say your answer should be B. DF/FB=EG/GC

Your question was if FB is parallel to BC, what must be true? A. and C. are not necessarily connected to FB and BC and do not prove that those two lines are parallel. while B. DF/FB = EG/GC does prove that they are parallel because the lines mentioned in the question, FG and BC, are attatched by the lines that are provided by answer B. I hope this helps!

What is the similarity of triangles?Similar triangles are those with the same form but different sizes. Examples of related objects are all equilateral triangles and squares with any side length. In other words, two triangles that are comparable have corresponding sides that are proportionately equal and corresponding angles that are congruent. The symbol "≈" above illustrates how the triangle looks similar.
Given that,
A right triangle ABC,
which contains two segments DE & FG
So according to properties of similar triangles, the ratio of length of the sides of the triangle is equal,
AB/AC = AD/AE
it can be further simplified as
AB/AD = AC/AE

In the system of equations above, r and s are nonzero constants. When these equations are graphed in
the xy-plane, the result is a pair of intersecting lines. At what point do the lines intersect?
Answer: (0, 0)
Step-by-step explanation:
We have the linear system:
y = r*x
y = s*x
We want to find the point where the lines intersect,
We know that
r*x = y = s*x
r*x = s*x
if r and s are different numbers (if r = s, this means that the two lines are the same line)
Then we have that the equality is only true when x = 0.
this means that the value of y is.
y = s*0 = r*0 = 0
So the point (x, y) where the lines intersect is (0, 0)

If 3b+2-6b=32+5b-2b, find b
I believe the answer is b= -5
Answer:
b=-5
Step-by-step explanation:
3b+2-6b=32+5b-2b(first you should collect like terms on each side.) so
3b-6b+2=32+5b-2b (lessen thing by both sides.)
-3b+2=32+3b (then you collect terms to one side)
-3b-3b=32-2
-6b=30 (you divide both sides by 6)
-b=5 (since b cannot be a negative u divide both sides by -1)
so..b=-5

Radius = 2cm
Step-by-step explanation:
We reverse equation for volume
V=πr2 h/3 becomes r2= V/( h* 3 *π)
We have height of 6cm so 6*3 = 18 Then V = 72/18π = 4
We then found the square r2 or ^2 or ^2 they are both same answers Radius = 2 as √4 = 2 and 4/2 also is 2
This radius is squared so we use the root √4cm and find r = 2.
