Answer:
Megan needs a 95 to get an average of 90.
Step-by-step explanation:
Add up the test scores Megan has earlier, you would get 355 as a result of all scores added. In order to get an average of 90%, you would need to accumulate 450 points which she will need to take her final exam on it. Subtract 355 from 450 to get a score of 95% in which she will need that score to average it to 90%.

PLEASE HELP!!!!!!!!!!!!!!!!!!
Answer:
Option C [tex](\sqrt{120}) [/tex]
Step-by-step explanation:
The easiest method is to find the number closest to the square of 11 i.e. 121. From all the options , ignore the square root , just find out the number
nearest to 121 ; we'll come to that 120 is very close to 121. So, [tex] \sqrt{120}[/tex] is the correct answer.
Let's verify all the options.
[tex] \sqrt{118} = 10.8627804912 = 10.86(appx)[/tex]
[tex] \sqrt{115} = 10.7238052948 = 10.72(appx)[/tex]
[tex] \sqrt{120} = 10.9544511501 = 10.95(appx)[/tex]
[tex] \sqrt{123} = 11.0905365064 = 11.09(appx)[/tex]
After verifying the values of all the options , 10.95 (appx value of [tex]\sqrt{120}[/tex]) is very close to 11.

1) Use the graph of f(x) = x2 to sketch the graph of the function h(x) = (x + 5)2
Answer:
[tex]f(x)=x^2[/tex]
[tex]h(x)=(x+5)^2[/tex]
To find:
The graph of h(x) using the graph of f(x).
Solution:
We have,
[tex]f(x)=x^2[/tex]
It a parent quadratic function. The graph of this function is an upward parabola with vertex at origin, i.e., (0,0).
Now,
[tex]h(x)=(x+5)^2[/tex]
It can be written as
[tex]h(x)=f(x+5)[/tex] [tex][\because f(x)=x^2][/tex]
It means, the graph of f(x) shifted 5 units left to get the graph of h(x)
Therefore, the graph of both functions are shown below.

Jack is buying a subscription to a magazine club the function C equals 45+3.75M describes the cost of a yearly subscription see in terms of the number of magazines he orders what is appropriate domain for the function
Given:
The cost function of a yearly subscription is
[tex]C=45+3.75M[/tex]
where, M is the number of magazines.
To find:
The appropriate domain.
Solution:
We have,
[tex]C=45+3.75M[/tex]
Domain is the set of input values and here input variable is M, which is number of magazines.
Linear function is defined for all input values. But the number of magazines can not be negative or decimal or fractional values. So, the possible value of M is always a whole number.
Therefore, the domain for the function is the set of whole numbers, i.e., {0, 1, 2, 3, ....}.
Diego measured the diameter and the circumference of several circular objects and recorded his measurements in the table. One of his measurements is inaccurate. Which measurement is it?
Answer:
flying disc
Step-by-step explanation:
The formula of the circumference of circles is: diameter × [tex]\pi[/tex]
I will find the circumference of each object to see if it matches the circumferences on the table.
Half dollar coin: 3[tex]\pi[/tex] = 10 (rounded to nearest integer) CORRECT!
Flying disc: 23[tex]\pi[/tex] = 72 (rounded to nearest integer) WRONG!
Jar lid: 8[tex]\pi[/tex] = 25 (rounded to nearest integer) CORRECT!
Flower pot: 15[tex]\pi[/tex] = 48 (rounded to nearest integer) CORRECT!
Based on the table, it was recorded that the circumference of the flying disc is 28, but we have calculated based on the diameter that it should be 72, so the measurement is inaccurate.

Step-by-step explanation:
The 2100 people surveyed said they would buy it again, meaning they were satisfied. A total of 3500 people were surveyed.
So 2100 / 3500 = 60%

Find the domain and the range of the following:
x y
3 2
5 7
1 4
9 2
3 7
Given:
The table of values.
To find:
The domain and range.
Solution:
The set of input values or x-values are known as domain.
In the given table, possible values of x are 1, 3, 5 and 9. So,
Domain = {1, 3, 5, 9}
The set of output values or y-values are known as range.
In the given table, possible values of y are 2, 4 and 7. So,
Range = {2, 4, 7}
Therefore, Domain = {1, 3, 5, 9} and Range = {2, 4, 7}.
You are making a poster to support your friend for homecoming. Your original photo is 4 inches by 6 inches. You want the photo on the poster to be 3 feet by 4/12 feet. What is the scale factor of this dilation?
Answer:
9
Step-by-step explanation:
Given that:
Dimension of Original photo = 4 inches by 6 inches
Intended dimension of model = 3 feet by 4 1/2 feets
Converting from feets to inches :
1 foot = 12 inches
Therefore,
Intended dimension of model :
3 feets = (3 * 12) = 36 inches
by 4 1/2 feets = (4 1/2 * 12) = 54 inches
Hence, scale factor required :
36 /4 = 9
54 / 6 = 9
Scake factor = 9

IM DEAD PLS HELP ASAP
Answer:
a. y = 0
b. x = 0
c. y = x
d. y = -x
Step-by-step explanation:
a. Since it is a horizontal line, its gradient does not change so its gradient shall remain as 0. Thus, y = 0x which is basically y = 0.
b. Since it is a vertical line, it is impossible to define its gradient or y-intercept but its x-intercept would always be at 0 so x = 0.
c. Since it is a line that is gradually getting higher across the x-axis, its gradient would be 1. It's y-intercept is 0 so the equation of this line would be y = 1x + 0, which is basically y = x. (We don't write 1x, but rather just x, putting zeros behind an equation is redundant)
d. Since it is a line that is gradually getting lower across the x-axis, its gradient would be -1. It's y-intercept is also 0 so the equation of this line would be y = -1x + 0, which is basically y = -x ((We don't write -1x, but rather just -x, putting zeros behind an equation is redundant)

help wit all
show work for all
I will mark brainllest
Answer:
Work shown below!
Step-by-step explanation:
Slope-intercept form: y = mx + b
11. [tex]y=\frac{2}{5}x+1[/tex]
12. 3x - 7y = 28
Subtract 3x from both sides;
-7y = -3x + 28
Divide both sides by -7
[tex]y = \frac{3}{7} x-4[/tex]
13. [tex]y+4=\frac{1}{2}(x+1)[/tex]
Distribute;
[tex]y+4=\frac{1}{2}x+\frac{1}{2}[/tex]
Subtract 4 from both sides;
[tex]y=\frac{1}{2}x-\frac{7}{2}[/tex]

Which function has the least value for the y-intercept?
Answer:
y-intercept is the value of y when x is equal to zero. Because the y intercept is a point on a graph, you'll usually write it in point/ coordinate form.
Step-by-step explanation:
The y-intercept is where the parabola of a function crosses (or intercepts) the y axis.
Which system is the solution of the graph?

CALCULATE THE NUMBER OF APPLES IN THE 12TH BAG
NOTE:PLS MAKE SURE THE FINAL ANSWER SAYS...APPLES
Step-by-step explanation:
The mean number of apples in each bag is 8. We have to calculate the number of apples in the 12 bag. Hence, there are 96 apples in 12 bags.
Answer:
9 applesStep-by-step explanation:
GivenTotal number of bags = 12Mean number of apples = 8To findNumber of apples in the 12th bagSolutionTotal number of apples is:
8*12 = 96Number of apples in 11 bags as per given table:
6*1 + 7*4 + 8*2 + 9*3 + 10*1 = 87Number of apples in the 12th bag:
96 - 87 = 9So there are 9 apples in the 12th bag
