Grandma Maude wanted a tall cake for her 80th birthday. The baker made a cake with 4x3 – x layers. Each layer was 2 + 3x2 cm. Which expression shows the total height of Grandma Maude’s cake?
Answers
Using proportions, it is found that the expression that shows the total height of Grandma Maude’s cake is:
[tex]t = 12x^5 + 5x^3 - 2x[/tex]
This question is solved by proportions, using a rule of three.The measure of one layer, in cm, was of [tex]2 + 3x^2[/tex]. In total, there were [tex]4x^3 - x[/tex] layers.The rule of three is:
1 layer - [tex]2 + 3x^2[/tex] cm

What is the function rule for the line?
Answers
Answer: It is f(x)= -3/2x-2
Step-by-step explanation: f(x) is the same as y. The formula for a line is slope-intercept form (y=mx+b). The -2 is the y-intercept, and the line intercepts the graph at -2. The slope is -3/2 because it rises 3 and goes to the left -2.
Has a slope of -2/5 and goes through (-10,-1)
Answers
Answer:
Below in bold.
Step-by-step explanation:
Using the point-slope form of a straight line equation:
y - y1 = m(x - x1)
y - (-1)) = -2/5(x - -10)
y + 1 = -2/5(x + 10)
y + 1 = -2/5x - 4
y = -2/5x - 5.
In standard form this is:
2x + 5y = -25.

Answers
The expression which best represents the volume of the can in discuss as evaluated from the formula; V = π r² h and as required is; 6.75π.
What is the volume of the can as described?It follows from the task content that the volume of the can whose radius is; 1.5 inches and height is; 3 inches is to be determined.
It is noteworthy to know that the volume of a can often the shape of a cylinder is given by the formula;
Volume, V = π r² h.
where, radius, r = 1.5 in.
height, h = 3 in.
Therefore, we have that the volume of the can can be evaluated as;
Volume, V = π × ( 1.5 )² × 3
Volume, V = 6.75 π.

Answers
Answer:

B. 36%
C. 16%
D. 4%
Step-by-step explanation:
13/25 people have freckles.
9/25 people have Blonde or red hair.
4/25 people have freckles and brown hair.
1/25 people have freckles and red hair.
Divide the fractions to get the percentages.
The probabilities are A. 52%, B. 56%, C. 16% and D. 4%
What is probability?A probability is a number that reflects the chance or likelihood that a particular event will occur.
Given that, Alan collects data about the students in his class. he records their hair colour and whether they have freckles,
P(E) = (Number of favourable outcomes) ÷ (Sample space).
There are total 25 students in data,
A) Students having freckles = 13
P(freckles) = 13/25% = 52%
B) Students having blonde or red hair = 14
P(blonde hair or red hair) = 14/25% = 56%
C) Students having freckles and brown hair = 4
P(freckles and brown hair) = 4/25% = 16%
D) Students with no freckles and red hair = 1
P(no freckles and red hair) = 4/25% = 4%
Hence, a. P(freckles) = 52%
b. P(blonde hair or red hair) = 56%
c. P(freckles and brown hair) = 16%
d. P(no freckles | red hair) = 4%

Troy is buying a car that costs $15,000. He
plans to get a 5-year loan to pay for it. He
can get a loan for $15,000 or he can pay
$3,000 from his savings and get a loan
for the rest. The savings account pays 2%
simple interest per year. The simple interest
rate for the loan is 0.5% per year.
a. How much interest over a 5-year
Answers
Answer:
300/75
Step-by-step explanation:
Cost of the Car = $15,000
a) Rate of interest received on savings(r) = 2%
Amount in savings account(p) =$3000
Time period(t) = 5 years
simple intrest.
Interest received on savings account = $300
b) Rate of interest on loan = 0.5%
IF P= 15000
intrest.
Difference between the interest = $75
c) Taking loan of the whole amount that is of $15,000 is more reasonable because though the interest is more but Troy will receive interest($300) from his savings account as well. But if he withdraws $3000 from savings and takes the loan for the rest of the amount, he would have no earnings.

Hello please help straight up answer I’ll give points thanks I’m just trying to pass
Answers
Answer:
I think it's 34°.
Step-by-step explanation:
The angle to the right of 3x+7 is the alternate interior angle to 2x+3, meaning that they are the same.
Now, that angle, 2x+3, and 3x+7, are on a line, which I'm assuming is a straight line with an angle of 180°. If it is, then (2x+3)+(3x+7)=180
Now you can solve for x.
2x+3+3x+7=180
5x+10=180
5x=170
x=34
Therefore, x=34°

Is it possible to arrange 152 books on a shelf so that the first shelf has 7 fewer books than the second shelf and 11 more than the third shelf?
Answers
Using a system of equations, it is found that since the solution of the system does not involve decimal numbers, it is possible to arrange the books in this way.
For the system, we consider that:
x is the number of books on the first shelf.y is the number of books on the second shelf.z is the number of books on the third shelf.In total, there are 152 books, hence:
[tex]x + y + z = 152[/tex]
The first shelf has 7 fewer books than the second shelf, hence:
[tex]x = y - 7[/tex]
Also, it has 11 more books than the third shelf, hence:
[tex]x = z + 11[/tex]
Then:
[tex]y - 7 = z + 11[/tex]
[tex]z = y - 18[/tex]
Then, replacing in the first equation:
[tex]x + y + z = 152[/tex]
[tex]y - 7 + y + y - 18 = 152[/tex]
[tex]3y = 177[/tex]
[tex]y = \frac{177}{3}[/tex]
[tex]y = 59[/tex]
The number of books in each shelf has to be countable, that is, cannot be decimal.
Then, since the solution of the system does not involve decimal numbers, it is possible to arrange the books in this way.To learn more about system of equations, you can take a look at https://brainly.com/question/14183076

If we look at the differences between the ratio numbers we see ...
14 -8 = 6
(x +6) -(x -3) = 9
That is, the numbers in the second ratio must be 9/6 = 3/2 times the numbers in the first ratio. In other words, ...

Tom is applying for a visa.
He has to pay £2,400 for the visa as well as a 8% charge on the visa price for an on-the-day service.
If Tom has 1 year to save, how much money should he save per month to be able to cover his costs?
Round your answer to the nearest £10.
Answers
Answer:
100
Step-by-step explanation:
The total amount Tom saved per month is equal to [tex]\£ 220[/tex] (nearest [tex]\£10[/tex]).
What is the amount?" Amount is defined as the total of all the given quantities as per given conditions."
According to the question,
The amount required to pay for a visa [tex]= \£ 2,400[/tex]
Percentage charges on the visa price as day service[tex]= 8\%[/tex]
Amount as day charge [tex]= 8\%[/tex] of [tex]2400[/tex]
[tex]= \frac{8}{100} \times 2400\\\\= \£192[/tex]
The total amount required for a visa [tex]= \£ (2400 + 192)[/tex]
[tex]= \£ 2592[/tex]
Tom has one year to save,
Therefore,
Amount Tom save in one month [tex]= \frac{2592}{12}[/tex]
[tex]=\£ 216[/tex]
≈[tex]\£ 220[/tex] ( round to nearest [tex]\£ 10[/tex])
Hence, the total amount Tom saved per month is equal to [tex]\£ 220[/tex] (nearest [tex]\£10[/tex]).
