Answer:
47
Step-by-step explanation:
First, we convert 20¾ pounds into ounces.
1 lb = 16 oz
20¾ pounds * 16 oz/lb = 332 oz
Now we divide 332 oz by 7 oz.
332/7 = 47 3/7
You can make 47 full bags, and you'll have 3/7 of an ounce left.

solve x and y in 2^x ×3^y =72
Answer:
x = 3 , y = 2
Step-by-step explanation:
We need to solvd the the given exponential equation , the equation is,
[tex]\bf\implies 2^x \times 3^y = 72 [/tex]
Now write 72 as prime factors of 2 and 3 ,
[tex]\bf\implies 2^x \times 3^y = 2^3 \times 3^2 [/tex]
On comparing ,
[tex]\bf\implies x = 3 \\[/tex]

what is f(x)? What point is on the graph of f?
Answer: A) -2; (2, -2)
Step-by-step explanation: If x is 2 then only the first two answers have the possibilty of being correct since in the coordinate pair the x coordinate is 2.
Sub in x and solve equation
[tex]\frac{x^2-2}{x-3}\\\frac{2^2-2}{2-3}\\\frac{4-2}{-1} \\\frac{2}{-1} \\-2[/tex]
f(x)=-2 so that is where the point of f is.

Step-by-step explanation:
If two people paint a wall, each will paint half of the sall
If jamie paints the entire wall in 54 minutes alone then he/she can paint half the wall in 54/2=27 minutes
The question said that it took 36 minutes all together, so if 27 minutes(jamies half) is subtracted from 36, we get that it took Connie 9 minutes for her half.
If connie paints an entire wall, then we multiply the time it took her( 9 minutes) by 2 to get 18 minutes.

How many ways can six of the letters of the word palindrome be selected and written in a row where either the first two letters are PA(in order) or the last two letters are ME (in order)
There are 48 ways to select and arrange six letters from the word "palindrome".
Case 1: First two letters are "PA" (in order)
In this case, to select four letters from the remaining seven letters of the word "lindrome" and arrange them.
The order of the selected four letters is important.
So, the number of ways for this case is:
Number of ways = 4! = 24
Case 2: Last two letters are "ME" (in order)
Similarly, in this case, to select four letters from the remaining
seven letters of the word "palindr" and arrange them.
The number of ways for this case is also:
Number of ways = 4! = 24
Now, the total Number of ways
= Number of ways in Case 1 + Number of ways in Case 2
= 24 + 24
= 48
Therefore, there are 48 ways to select and arrange.

Use the graph to answer the questions.
1) write into vertex form.
2) identify the vertex, focus, and directrix.
Answer:
y = 2( x+5)^2 -4
Vertex (-5,-4)
directrix y = -33/8
focus (-5, -31/8)
Step-by-step explanation:
First identify the vertex, which is the minimum
Vertex = (-5,-4)
The vertex form is y = a( x-h)^2 + k
y = a( x- -5)^2 -4
y = a( x+5)^2 -4
We need to determine a
Substitute a point on the graph
(-3,4) is on the graph
4 = a( -3+5)^2 -4
4 = a( 2)^2 -4
4 = 4a -4
Add 4 to each side
8 = 4a
Divide by 4
8/4 = a
a=2
y = 2( x+5)^2 -4
To find the focus and directrix, write in standard form
4p(y-k)=(x-h)^2
y+4 = 2(x+5)^2
1/2 (y+4) = (x+5)^2
4p = 1/2
p = 1/8
The focal length is 1/8
Subtract this from the y coordinate to get the directrix
y = -4 -1/8
y = -32/8 - 1/8 = -33/8
Add this to the y coordinate to get the coordinate for the focus the x coordinate the same
(-5, -4+1/8)
(-5, -32/4+1/8)
(-5, -31/8)
Which of the following describes a compound event?
A. Tossing 5 coins and getting 4 heads
B. Rolling 3 on a die
C. Tossing a coin and getting tails
D. Drawing the ten of diamonds from a deck of cards
Answer:
A. Tossing 5 coins and getting 4 heads
Step-by-step explanation:
Compound events may be described as events whose occurence has more than one possible outcome, that is the number of possible events is more than one. From the options given above, Rolling 3 on a die, this event has only one possible outcome, which is rolling 3 ; tossing a coin and getting tails also has one obe possible outcome. Drawing 10 diamonds from a deck also focuses on one event which is drwinh diamonds. However, tossing 5 coins and getting 4 heads involves that the 5th toss will be tail. This has more than one event and thus a compound event.
Answer: A.
Step-by-step explanation:
Tossing five coins and getting four heads is a compound event as the coins and cards are different

Sorry for asking for help for all of these questions but I’m really struggling so I need help again
Answer:
c. 17
Step-by-step explanation:
So the equation is 3g = 51.
What we are given is {15, 16, 17}
Let's plug in each of these into the equation for g.
3(15) = 51
45 = 51
45 does not equal 51.
3(16) = 51
48 = 51
48 does not equal 51
3(17) = 51
51 = 51
51 does equal to 51.
So 17 is your answer, because if you plug it into the equation, you get an equivalent answer of 51.

The diameter of a circle is 3 cm. Find the circumference to the nearest tenth.
Answer:
The answer is 9.4 cm.
Step-by-step explanation:
To solve for the circumference of the circle, use the circumference formula, which is C = 2 [tex]\pi[/tex] [tex]r[/tex].
Next, in the problem, the circle has a diameter measure but no radius measure. To find the radius of this circle, divide the diameter (3 cm) by 2, and it will equal 1.5 cm. The radius is being divided by 2 because the radius of any circle is equal to half the diameter of the circle.
Then, plug in the information given from the problem into the formula, and the formula will look like C = (2) ([tex]\pi[/tex]) (1.5 cm).
Finally, solve the equation, and the answer is 9.4 cm.

What is the probability of flipping a coin 12 times and getting heads 3 times? Round your answer to the nearest tenth of a percent. O A. 5.4% O B. 12.5% O C. 12.1% O D. 19.3% SUBMIT
==================================
Explanation:
We use the binomial probability formula here
P(k) = (n C k)*(p)^k*(1-p)^(n-k)
In this case, there are n = 12 trials and p = 0.5 is the probability of getting heads. The value of k = 3 means we want 3 heads.
So,
P(k) = (n C k)*(p)^k*(1-p)^(n-k)
P(3) = (12 C 3)*(0.5)^3*(1-0.5)^(12-3)
P(3) = 220*(0.5)^3*(1-0.5)^(12-3)
P(3) = 0.0537109375
P(3) = 0.054
P(3) = 5.4%
