Answer:
242 + 118 - 109
Step-by-step explanation:
collected- 360 apples total ( 242 + 118 )
sold- 109 apples

HELP!! The side of a square is 3 raised to the 5/2 power inches. Using the area formula A = s squared, determine the area of the square.
Answer:
3^5/2 is 15.5885.
Step-by-step explanation:
This is plug in math! I'd recommend to get a Ti-84 (makes math like this so much easier)
Answer:
243 square inches
Step-by-step explanation:
The area is the square of the side length:
A = s^2
A = (3^(5/2))^2 = 3^(5/2*2) = 3^5 = 243
The area of the square is 243 square inches.

y=3x+12 positive or negative
Answer:
x = -4 thus negative
Step-by-step explanation:
Solve for x:
3 x + 12 = 0
Hint: | Isolate terms with x to the left hand side.
Subtract 12 from both sides:
3 x + (12 - 12) = -12
Hint: | Look for the difference of two identical terms.
12 - 12 = 0:
3 x = -12
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides of 3 x = -12 by 3:
(3 x)/3 = (-12)/3
Hint: | Any nonzero number divided by itself is one.
3/3 = 1:
x = (-12)/3
Hint: | In (-12)/3, divide 12 in the numerator by 3 in the denominator.
12/3 = (3×4)/3 = 4:
Answer: x = -4

Answer:

0.00365 in scientific notation
find the area of the figure
Answer:
90 inches squared
Step-by-step explanation:
To do this you would first find the area of the 2 triangles shown on the side so we would do 5 times 2 divided by 2 since that is how we solve this problem so we would get 5 inches squared for the 2 triangles then we would find the area of the square which is 100 since it is a 10 by 10 then you would subtract 5+5 by 100 which is 90 so 90 inches squared would be the answer
Answer:
Your correct answer is 90 sq. in.
Step-by-step explanation:
Find the area of the 2 triangles that are shown on the side.
5 x 2 divided by 2 = 5 sq. in.
Now, find the area of the square
The answer for this is 100 because it is a 10 x 10
Next, subtract
5 + 5 by 100 = 90
For every pound a company spends on advertising it spends £.0.49 on it website express the amount spent on advertising to it website as a ratio in it simplest form
Answer:
1/0.49
Step-by-step explanation:
Every pound = 1 pound
And for every one of this company spends 0.49pound
To express this in a ratio is 1:0.49
Which is also 1/0.49 in fraction.
A ratio tells us how many times a number contains another number. It compares two numbers in relation to each other.
Therefore 1/0.49 expresses the amount spent on advertising as a ratio
Which relation is also a function?
Answer:
Step-by-step explanation:
A relation from a set X to a set Y is called a function if each element of X is related to exactly one element in Y. That is, given an element x in X, there is only one element in Y that x is related to. For example, consider the following sets X and Y.
When we say about relation is a function
The given table relation is not a function
the graph relation is not a function
Given :
A relation is a function when all x values has exactly only one y value .
Each input has only one output for a function .
When x values are repeated then we can say that there is two output .
So that is not a function .
In the given table, we have x=5 repeated twice .
when x=5 there are two outputs [tex]-3 and -2[/tex]
for x=5, there are two outputs.
The given table relation is not a function
Now we consider the graph
When x=2 , there are 2 y values [tex]-3 \; and \; -4[/tex]
So input 2 has two output values
Hence , the graph relation is not a function

B. p varies inversely as r
Step-by-step explanation:
Since, p varies directly as q
[tex] \therefore p\:\:\alpha \:\:q\\
\therefore p= kq.. (k = constant)... (1)\\
[/tex]
Since, q varies inversely as r
[tex] \therefore q\:\:\alpha \:\:\frac{1}{r} \\
\therefore q= \frac{k}{r} .. (k = constant)... (2)\\
[/tex]
From equations (1) & (2)
[tex] p = k\times \frac{k}{r}\\
p = \frac{k^2}{r}\\
p\:\:\alpha \:\: \frac{1}{r}\\
[/tex]
Hence, p varies inversely as r.

let a and b be positive integers. 23^a x 23^b
Answer:
23 ^ ( a+b)
Step-by-step explanation:
23^a *23^b
Since the bases are the same, we can add the exponents
23 ^ ( a+b)
Answer:
23^(a+b)
Step-by-step explanation:
A^x*A^y = A^(x+y)
you can think of it like this
A^x = A*A*A*.......*A x times
A^y = A*A*A*....*A y times
therefore A^x * A^y = A*A*A*...*A (x+y) times
=A^(x+y),
so in our case A = 23, and x and y were a and b, so 23^a * 23^b = 23^(a+b)

The parabola opens downward so a<0
zeros are: x₁=-1 and x₂=2, so the factors are:
(x - x₁) = [x - (-1)] = (x + 1)
(x - x₂) = (x - 2)
which gives: - (x + 1)(x - 2)

8. Find the equation of a line in slope intercept form that is parallel to the line y = -2x - 3 that goes
through the point (2, 1).
Work:
Answer:
Step-by-step explanation:
Hey there!!
To solve this type of question, use these steps.
Find these 1st equation by using one point formula of point.After this from equation 2 find slope, by comparing it with y= mx + c if it is in slope intercept form. Then, as per the conditions of parallel lines, use m1=m2, then put the value of m1 in equation 1st.Then simplify them.So, let's work with these steps.
Now,
The equation of a st.line passing through point (2,1) is,
[tex](y - y1) = m1(x - x1)[/tex]
Put all values.
[tex](y - 1) = m1(x - 2)[/tex]
It is the 1st equation.
Another equation is,
y = -2x -3.......(ii)
Comparing the equation with y = mx+c.
Therefore, from equation (ii)
m2 = -2
Now, as per condition of parallel lines,
m1=m2= -2
Putting the value of m1 in equation 1st.
[tex](y - 1) = - 2(x - 2)[/tex]
y - 1 = -2x + 4
y = -2x +5.
Therefore, the equation is y = -2x +5.

Kenji earned the test scores below in English class. 79, 91, 93, 85, 86, and 88 After his next test, his mean and median scores both change to 88. How much does he earn on this test?
Answer:
Step-by-step explanation:
We need to find what number he got on the test.
We know he got a bigger number than 88.
79+85+86+88+91+93+x.
Let's substitute x for 94.
79+85+86+88+91+93+94/2 = 88.
Since any other number thats near 94 doesn't equal 88, we know that this is exactly the right answer.
A ship must be unloaded by two cranes in 12 hours. Both cranes worked for 8 hours and then one of them broke. The rest of the work was done by the other crane in 7 hours. How long would each crane take to do the entire job if it was working alone? Thank you!
Answer:
6 hours
Step-by-step explanation:
8 hours x 2 cranes = 16 hours of total work
After one broke
7 hours x 1 crane = 7 hours of total work
16 + 7 = 23 hours
It would take 23 hours for one crane to do the whole job.
Abdul wants to hang a square poster that measure 1 1/2 feet on a side in the center of a 12-foot-long wall. How far from the end of the wall should abdul place the side of the poster?
Answer:
5.25 feets
Step-by-step explanation:
Given the question :
Abdul wants to hang a square poster that measure 1 1/2 feet on a side in the center of a 12-foot-long wall. How far from the end of the wall should abdul place the side of the poster?
Length of one side of Square poster = 1 1/2 Feets = 3/2 feets
Length of wall = 12 feets long
Since Abdul wants the poster to be centered in the wall; then the picture should be placed such that there must be equal space left on either side of the wall after hanging.
Hence, (12/2 - 1 1/2) = (6 - 0.75) feets
= 5.25 feets
