i need help , what’s the answer ?
Answer:
D,
Step-by-step explanation:
that's because you only factorise when you have a common factor, ax-3b cannot be factorised because they have nothing in common so it is wrong to use x to factorise it. If you want to be sure that it is not factorisable, try expanding it and you'll see that you will not get the same answer.

Step-by-step explanation:
The following list details the numbers of tickets sold for a talent show grade 9:22; grade 10:32; grade 11: 41; and grade 12:30. What are the
domain and range of this relation?
A domain: (22, 32, 41, 30); range: {9, 10, 11, 12}
B. domain: {9, 22, 10, 32); range: {11, 41, 12, 30}
C. domain: {9, 10, 11, 12); range: (22, 32, 41, 30)
D
domain: {11, 41, 12, 30}; range: {9, 22, 10, 32)
Answer: C. domain: {9, 10, 11, 12); range: (22, 32, 41, 30)
Step-by-step explanation:
The data set is:
(9, 22)
(10,32)
(11, 41)
(12, 30).
In the usual notation, the number at the left is the input (belons to the domain) and the number in the right is the output (belongs to the range).
Then the domain would be:
{9, 10, 11, 12}
and the range:
{22, 32, 41, 30}

S=(n-2).180
(Solve for n)
Answer:
[tex]n = \frac{S}{180} + 2[/tex]Step-by-step explanation:
S = 180 × ( n - 2)
To solve for n divide both sides by 180°
That's
[tex]n - 2 = \frac{S}{180} [/tex]Add 2 to both sides in order to isolate n
That's
[tex]n + 2 - 2 = \frac{S}{180} + 2[/tex]We have the final answer as
[tex]n = \frac{S}{180} + 2[/tex]Hope this helps you
Multiplying a number by which of the following would result in a smaller number?
O 100
O 101
O 102
10-1
Answer:
10^(-1)
Step-by-step explanation:
Recall that a value that is multiplied by a number that is between 0 and 1 will result in a number that is smaller than the original number.
the first 3 are all greater than 1, hence will result in a greater value if when multiplied with another number.
The last one is 10^(-1) = 0.1
Anything multiplied by 0.1 will result in a value that is 1/10th of the original value.
Hence this is the answer.
Answer:
10/\-1 is correct
Step-by-step explanation:

Step-by-step explanation:
[tex]C=\frac{1}{2}t(c1-c2)\\2(C)=2(\frac{1}{2}t(c1-c2))\\2C=t(c1-c2)\\\frac{2C}{c1-c2}=\frac{t(c1-c2)}{c1-c2}\\t=\frac{2C}{c1-c2}[/tex]
Answer:
[tex]t=\frac{2C}{c_{1}-c_{2}}[/tex]
Step-by-step explanation:
[tex]C=\frac{1}{2}*t(c_{1}-C_{2})\\\\[/tex]
Multiply both sides by 2,
[tex]2*C=2*\frac{1}{2}*t*(c_{1}-c_{2})\\\\2C=t*(c_{1}-c_{2})\\\\\frac{2C}{(c_{1}-c_{2})}=t\\\\\\t=\frac{2C}{c_{1}-c_{2}}[/tex]

The area of a rectangular wall of a barn is 90 square feet. It’s length is 8 feet longer than twice it’s width. Find the length and width of the wall of the barn
Answer: The answer is that the length is square ft, and the width is .
Step-by-step explanation:
The length and width of the wall of the barn are 18, 9
What is the area of rectangle?The area of rectangle is product of length and width
Given area of rectangle is 90 ft²
given length = 8 ft + 2ₓ width
l = 8 +2 w
area = l × w
90 = (8 +2 w) × w
90= 8w +2w²
2w²+ 8w -90 =0 or w²+4w - 45 =0
On solving w= 9, -5
as width cannot be negative so w= 9
l= 8+2×9
l=26
Thus the length and width of the wall of the barn are 18, 9

The city of Atlanta plans to hold a parade after the Atlanta Falcons win the Super Bowl. They intend to allow fans to watch from the sidewalk on both sides of Peachtree Street. The parade route will be 1 mile long (5,280 feet are in a mile) and the sidewalks are 10 feet deep. If the average person takes up 3 square feet of space, what is the estimate for the number of people who can attend the parade?
Answer:
17600 people.
Step-by-step explanation:
Given that The parade route will be 1 mile long (5,280 feet are in a mile) and the sidewalks are 10 feet deep.
The area of the parade route will be
5280 × 10 = 52800 ft^2
If the average person takes up 3 square feet of space, then, divide the area by 3. That is,
52800 / 3 = 17600 people.
Therefore, the estimate for the number of people who can attend the parade will be 17600 people.

Chicken eggs can be categorized as large if they weigh at least 2 ounces. Clare weighs 48 large eggs and finds that they have a mean weight of 2.1 ounces and a mean absolute deviation of 0.08 ounces. Interpret 0.08 ounces in this situation.
Answer: The average difference of weights of all 48 eggs from mean eight is 0.08.
Step-by-step explanation:
The mean absolute deviation of a data interprets the mean distance between each data point and the mean.
When this distance goes larger it means data has greater variability
Given, 48 large eggs have a mean weight of 2.1 ounces and a mean absolute deviation of 0.08 ounces.
It means that the average difference of weights of all 48 eggs from mean eight is 0.08.

Old Mc Donald raises ducks and cows. The animals have a total of 100 heads and 354 feet. How many ducks and how many cows does Old Mc Donald have?
Answer:
The number of ducks Old Mc Donald raises are 23 and the number of cows Old Mc Donald raises are 77.
Step-by-step explanation:
We are given that Old Mc Donald raises ducks and cows. The animals have a total of 100 heads and 354 feet.
Let the number of ducks Old Mc Donald raises be 'x' and the number of cows Old Mc Donald raises be 'y'.
So, according to the question;
The first condition states that the animals have a total of 100 heads, that means;[tex]x+y=100[/tex]
[tex]x=100-y[/tex] -------------------- [equation 1]
{because one head of a duck and one head of cow}
The second condition states that the animals have a total of 354 feet, that means;[tex]2x+4y=354[/tex]
[tex]x+2y=177[/tex] --------------- [equation 2]
{because there are two feet of a duck and four feet of cow}
Now, putting the value of x in equation 2 we get;
[tex]100-y+2y=177[/tex]
[tex]y=177-100[/tex]
y = 77 cows
Putting this value of y in equation 1 we get;
x = 100 - y
x = 100 - 77 = 23 ducks
Hence, the number of ducks Old Mc Donald raises are 23 and the number of cows Old Mc Donald raises are 77.

Step-by-step explanation:
you can just plug in the numbers to get your answer and if two numbers aren't the same then its not a solution

1.) A boy has $12 saved. He decides to start saving on a regular basis. He figures out that he
can
save $1.50 per day. What is the total amount he will have saved after 1 day? 2 days? 3 days?
17days? X days?
Answer:
12 + (1.50 multiplied by x)
Step-by-step explanation:
You have 12 dollars as the base. For every x days (x is the amount of how many days) he'd save $1.50. For one day, he'd save 1.50 plus his 12 dollars. Two days, he'd save 12 + (1.50 x x). Three, it'll be 12 + (1.50 x x) and so on.

If 3x - 8= -2, find the value of x - 6.
Answer:
x-6 = -4
Step-by-step explanation:
3x - 8= -2
Add 8 to each side
3x - 8+8= -2+8
3x = 6
Divide by 3
3x/3 = 6/2
x =2
We want to find x-6
2-6 = -4
Answer: - 4
Step-by-step explanation:
3x - 8 = -2
3x = -2 + 8
3x = 6
x = 6/3
x = 2
so, therefore x - 6 => 2 - 6 = -4
