I thought of a number R added 12 and then doubled the result
Answer:
2r+24
Step-by-step explanation:
The number is R · R is added to 12 : R + 12. Double the result: 2 (R + 12). = 2 R + 24. So the answer is ultimatley 2r+24.
Answer: 2R+24
Step-by-step explanation:
(R+12)*2= ==> multiplication comes before addition, so in order to indicate that addition occurs before multiplication, there should be parentheses around
2(R+12)=
2R+2*12=2R+24
Rochelle needs to pack a picture frame that measures 7611 inches on each side. Will it fit into a box that measures 7.52 inches on each side? Explain.
No, the picture frame will not fit into a box that measures 7.5 inches on each side because the side of the frame will be greater than it that is 7.54 inches.
Length of picture frame is given as:
= 7 (6 / 11)
= 7.54 inches
The length of Box is given as = 7.5 inches
From the above, we can see that the length of the box is smaller than the length of the picture frame.
So, the picture frame will not be able to fit in the box.
Therefore, we get that, the picture frame will not be able to fit into a box that measures 7.5 inches on each side because the side of the frame will be greater than it that is 7.54 inches.

Answer:
[tex]\textsf{C}\quad f^{-1}(x)=24-6x[/tex]
Step-by-step explanation:
You want the inverse function of f(x) = 24 -x/6.
Inverse functionThe function relates x to y by y = f(x). The inverse function gives the reverse relation: x = f(y). Solving this for y gives the inverse function in the form you want.
x = f(y)
x = 4 -y/6 . . . . . use definition of f(x)
6x = 24 -y . . . . multiply by 6
y = 24 -6x . . . . add y-6x
f⁻¹(x) = 24 -6x . . . . write using function notation

By using the given graph, we can see that f(-5) = 3.
How to find the value of f(-5)?
Here we have an image with the graph of the function y = f(x).
Remember that each point on that grid has the coordinates (x, y), where the values of x are on the horizontal axis, and the values of y are in the vertical axis.
So, if we want to find f(-5), then we want to see what value of y takes f(x) when x = -5.
So, first we need to go to the horizontal axis and find x = -5.
Once we find that value, now we need to move up or down along a vertical line (depending on where is the graph of the function). In this case we would move upwards. Now, count how many units we move up until we hit the graph of the function, that number of units will be the value of y.
In this case, we need to move 3 units upwards to hit the graph, then we have y = 3.
This means that the value of the function when x = -5 is y = 3, so we can write:
f(-5) = 3

Find y if the slope between (1,y) and (-5,-1) is 2/3
Answer:
y = 3
Step-by-step explanation:
Points: (1, y), (-5, -1)
slope = (y_2 - y_1)/(x_2 - x_1)
slope = (-1 - y)/(-5 - 1) = (-1 - y)/(-6)
slope = 2/3
(-1 - y)/(-6) = 2/3
Multiply both sides by -6.
-1 - y = -6 × 2/3
-1 - y = -12/3
-1 - y = -4
-y = -3

Sid makes a living baking cakes. For each cake, he uses 1 3/4 cups of sugar, 4 1/5 cups
of flour, and 3/10 of a cup of milk. How many cups of ingredients will Sid need to
make 4 cakes? Please I need the answer
By adding the number of cups needed for each cake, we conclude that you will need 25 cups of ingredients to make the 4 cakes.
How many cups of ingredients sill Sid need for 4 cakes?We know that the recipe calls for:
(1 + 3/4 ) cups of sugar.(4 + 1/5) cups of flour.3/10 of a coup of milk.That is for a single cake, so in a single cake you need a total of cups given by the sum of the above quantities, this gives:
(1 + 3/4) + (4 + 1/5) + 3/10 = (1 + 4) + (3/4 + 1/5 + 3/10)
= 5 + (3/4 + 2/10 + 3/10) = 5 + (3/4 + 5/10) = 5 + (3/4 + 1/2) = 5 + 5/4
= 5 + 4/4 + 1/4 = 6 + 1/4
Each cake needs (6 + 1/4) cups of ingredients, so 4 cakes will need:
4* (6 + 1/4) = 24 + 4/4 = 25
You will need 25 cups of ingredients to make the 4 cakes.

Lupe put $24000 in a certificate of deposit that gained interest at a rate of 5.5%. How much interest did the account gain after 3 months?
He gained $330 of interest in the three months.
Here we will use the Simple interest formula
Simple Interest (SI) = Simple Interest (SI)
initial principal balance = P = 24000
annual interest rate = r = 5.5
time (in years) = t = 3 months out of 1 year
= 3/12 = 1/4
Lets substitute the values in the formula
Simple Interest (SI) = (P × R × T)/100
= (24000 × 5.5 × 1/4)/100
= 330
What is simple interest?Simple interest is a quick and straightforward approach to figure out how much interest has accrued on a sum of money. Interest is always applied to the main sum, and there is a constant rate of interest applied during the course of the calculation.
Any bank where we deposit money pays us interest on the amount when we do so. There are other forms of interest charged by banks, but simple interest is one of them. To begin with, let's define a loan before delving further into the idea of simple interest.

B) The reason why Susan had a higher retirement savings than bill is because Susan started investing 10 years earlier than bill and so her investment had a longer period to compound.
How to interpret Exponential graphs?A) From the given exponential graph, we see that Chris curve was simialr to that of susan between ages 25 to 35 and suddenly Chris curve began to rise at a faster rate than that of Susan after that until when retired at 65 years of age.
Since we are told that chris continued that amount till retirement at 65, we are told that susan contributed the same amount for only that period between ages 25 and 35. Thus, it means that the reason why Chris had higher savings by retirement age, is because he saved $5000 annually from ages 25 to 65 while susan did so only from ages 25 to 35 .

Inequality is like an equation which shows the relationship between two or more variables but in greater than,less than,greater than or equal to ,less than or equal to signs.
Because we have to include 26 in the inequality so we need to fill the circle on 26. So, the correct option showing the correct inequality is third.

The three angles in a triangle are in the ratio 3:4:5. Find the angles
Please help me with 1-4. I will give an Brainly and a bunch of extra points.
Answer:
1. A U C = {a, b, c, d, e}
2. B intersect A = {a, b, d}
3. B' = {c, f, g, h}
4. A - (B intersect C') = {a,c}
Step-by-step explanation:
U is a big set with all the letters a through f in it. Set A, B, and C are subsets of U. They have some of the letters in them. You could pick out the contents of set A, for example, from set U. Same with B and C. There's a little bit of overlap between A and B and C.
So for #1, the U shaped symbol means "Union" and you can remember that because of the U shape symbol. "Union" means throw everything in all together. A U C means all of A and all of C all together. But you don't have to write repeats, just list the letters once.
A is {a,b, c, d} and C is {a, e} so A U C is all of both of them:
{a, b, c, d, e}
The upsidedown Usymbol is "intersect" and that is only what the two sets have in common (whats the same) between the two sets.
BintersectA is what is the same in B{b,e,a,d} and A{a,b,c,d}. They both have a, b and d so that is the answer to BintersectA = {a,b,d}
The "apostrophe" looking mark means "Not this set". So B' means NotB. You list everything that is NOT in B. B is {b,e,a,d} so B' is NotB = {c,f,g,h}
The last one has what looks like a minus sign. Thats like normal "takeaway" along with parenthesis, use that normally like grouping/"do this first" and also intersect and Not. So basically all the work, all in one problem.
C = {a,e} so C' is NotC is {b,c,d,f,g,h}
The BintersectC' is what are the same beween B and NotC:
BintersectC' = {b,d}
A take away {b,d}
would be
{a,b,c,d} - {b,d}
= {a,c}
