if the evaluated answer is correct (but my answer above is correct) it would be -4+6+3 then the answer would be 5 but I am not sure
Joe ate twice as many pieces of Halloween candy as Ed. Together they ate 48 pieces.
How many pieces of candy did Ed eat?
A. 12
B. 16
C. 24
D. 32
Answer: 16
Step-by-step explanation:
Let the number of candy Ed took be denoted as "x"
Since Joe ate twice the amount of candy Ed ate, then the number of candies joe ate will be denoted as "2x"
Since all together they ate a total of 48 candies, then the sum of the candies eaten by Joe and Ed is what gives a total of 48
This means:
2x + x = 48
3x = 48
X = 16.
Add (-2x + 4) + (4x + 6)
A) 2x + 10
B 6x + 10
C) 2x - 2
D) 6x-2
Answer:
A. 2x + 10

A bag contains 9 red, 7 blue, and 4 yellow marbles. If a marble is chosen at random from the bag, what is the probability that it is NOT yellow? (in fraction form) A) 1 5 B) 1 3 C) 3 5 Eliminate D) 4 5
Answer:
D
Step-by-step explanation:
if you add all the numbers together you get a total of 20. if you add the non yellow marbles together you get 16. so the fraction is 16/20. then you shorten the fractions by dividing the numbers. both are divisible by 4, so the final answer is 4/5.
Pls answer its khan academy I really need it
Answer:
Step-by-step explanation:
Note the f(0) = 9
and f(1) = 15
Since, f(x) = abˣ substituting for x, we get:
9 = f(0) = a . b⁰ = a
⇒ a = 9
Now, f(1) = 15
⇒ 15 = a . b¹
⇒ 15 = 9 . b
⇒ b = 15/19
Therefore,
f (r) = 9. (5/3)
Hence, the answer.
Transform the given function f(x) as described. f ( x ) = x 3 Translate right 2 units Translate up 3 units
Answer:
Step-by-step explanation:
f(x) = x^3
To get this to move right, you must do the opposite to what you think you should do.
f(x) =(x - 2)^3.
That looks like it should go left, but it doesn't. It does go right. Suppose you want to know where (0,0) has moved to. If you put x = 2 into x - 2 you get a value of y = 0. That's where the point 0,0 has moved to. It has gone to 2,0
Now you want f(x) to move up 3 units.
f(x) = (x - 2)^3 + 3 The y value lf x = 2 moves up 3 units
Let's see if this is correct.
If you look at the graphs,
The red one is y = x^3The blue one is y = (x - 2)^3The green one is y = (x - 2)^3 + 3The point 0,0 has been marked for the blue one as it shifts to the right and becomes (2,0) and up 3 in the green graph.

PLEASE HELP ME TO ANSWER THIS QUESTION.
A right pyramid PQRST has a rectangular base QRST. Given
that W is the midpoint of QS and RT, the lengths of QT = 8 cm,
TS = 6 cm and point P is vertically above point W, calculate
(a) PT, in cm, if PW = 12 cm
(b) the value of < PTR [angle PTR]
THANK YOU!!!
Answer:
(a) PT = 13 cm
(b) <PTR = [tex]39.7^{o}[/tex]
Step-by-step explanation:
(a) Applying the Pythagoras theorem to QST, we have;
[tex]QS^{2}[/tex] = [tex]ST^{2}[/tex] + [tex]QT^{2}[/tex]
= [tex]6^{2}[/tex] + [tex]8^{2}[/tex]
[tex]QS^{2}[/tex] = 36 + 64
100
QS = [tex]\sqrt{100}[/tex]
= 10
QS = 10 cm
Since QS = TR, then;
WT = [tex]\frac{1}{2}[/tex] TR
= [tex]\frac{1}{2}[/tex] x 10
WT = 5 cm
Thus, applying Pathagoras theorem to PWT;
[tex]PT^{2}[/tex] = [tex]PW^{2}[/tex] + [tex]WT^{2}[/tex]
= [tex]12^{2}[/tex] + [tex]5^{2}[/tex]
= 144 + 25
[tex]PT^{2}[/tex] = 169
PT = [tex]\sqrt{169}[/tex]
= 13
PT = 13 cm
(b) To determine <PTR, TR = 10 cm. Apply the required trigonometric function;
Cos θ = [tex]\frac{adjacent}{hypotenuse}[/tex]
Cos θ = [tex]\frac{10}{13}[/tex]
= 0.7692
θ = [tex]Cos^{-1}[/tex] 0.7692
= 39.7179
θ = [tex]39.7^{o}[/tex]
Therefore, <PTR = [tex]39.7^{o}[/tex]

The perimeter of a triangle is 29. One side of a triangle is 5 less than twice the side of the shortest length. The third side is 6 more than the shortest side. What are the lengths of the triangle?
Answer:
7, 9, 13Step-by-step explanation:
Let the sides of the triangle be a, b and c.
We have:
P = a + b + c = 29a = 2b - 5c = b + 6Substitute values and solve for b:
2b - 5 + b + b + 6 = 294b + 1 = 294b = 28b = 7Find a and c:
a = 2*7 - 5 = 14 - 5 = 9c = 7 + 6 = 13The sides are: 7, 9, 13

An auditorium has 40 rows of seats. There are 20
seats in the first row. Each row has 2 more seats
than the row before.
Identify the number of seats in the first 4 rows:
Answer:
140 seats
Step-by-step explanation:
40 rows
1ˢᵗ row = 20 seats
39 next rows = 2×20 = 40 seats
First 4 rows = 20 seats + 3(40) seats = 140 seats
➪the 2ⁿᵈ, 3ʳᵈ and 4ᵗʰ rows have equal number of seats = 40 seats

Review the graph of f(x).
On a coordinate plane, a curve approaches y = 2 in quadrant 2 and curves down and approaches x = negative 1 in quadrant 3. Another curve approaches x = negative 1 in quadrant 2, curves down through (0, 5), and approaches y = 2 in quadrant 1.
Which statement relates limits to an asymptote of the function?
The graph shows Limit of f (x) as x approaches plus-or-minus infinity = 2 so the function has a vertical asymptote at x = 2.
The graph shows Limit of f (x) as x approaches plus-or-minus infinity = negative 1 so the function has a vertical asymptote at x = –1.
The graph shows Limit of f (x) as x approaches plus-or-minus infinity = 2 so the function has a horizontal asymptote at y = 2.
The graph shows Limit of f (x) as x approaches plus-or-minus infinity = negative 1 so the function has a horizontal asymptote at y = –1.

Find the Compound Interest.
Principal: 1,000
Interest Rate: 3%
Time: 3 years
Answer:
92.727
Step-by-step explanation:
The formula for compound interest is [tex]P((1+i)^{t} -1)[/tex], where P is the principal amount, i is the interest rate and t is the time. Sub your values into this formula to find your answer.
1000((1+0.03)³-1)
1000(1.03³-1)
1000(1.092727-1)

Use the graph below to find the indicated function Value. y=f(x); f(4)
The value of f(4) is 3 if the graph of the function is shown in the picture, the answer is 3.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that:
The graph of the function is shown in the picture.
From the graph the value of f(4) can be evaluated as follows:
y = f(x)
Plug x = 4
y = f(4)
From the graph:
Draw a vertical line from point 3 on the x-axis and when it cuts the curve draw a horizontal line when the line cuts the y-axis note the point.
y = f(4) = 3
Thus, the value of f(4) is 3 if the graph of the function is shown in the picture, the answer is 3.

What is the volume of a rectangular prism with length equal to 13,width equal to 6 and height equal to 4
Given:
Length of the rectangular prism = 13 units.
Width of the rectangular prism = 6 units.
Height of the rectangular prism = 4 units.
To find:
The volume of the rectangular prism.
Solution:
We know that the volume of the rectangular prism is:
[tex]V=l\times b\times h[/tex]
Where, l is length, b is breadth or width and h is the height of the rectangular prism.
Putting [tex]l=13,b=6,h=4[/tex] in the above formula, we get
[tex]V=13\times 6\times 4[/tex]
[tex]V=312[/tex]
Therefore, the volume of the given rectangular prism is 312 cubic units.

Answer:
1/12
hope this helps
have a good day :)
Step-by-step explanation:
The solution is 1/12 , is the simplest form of 1/6 divided by 2.
What is division?Division is the process of splitting a number or an amount into equal parts.
Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.
here, we have,
1/6 divided by 2
i.e. 1/6÷ 2
=1/6* 1/2
=1/12
Hence, The solution is 1/12 , is the simplest form of 1/6 divided by 2.
