Answer:
Cost of each book = 14.5
Step-by-step explanation:
Given:
Total amount spend = 52.50
Cost of calendar = 9
Number of books = 3
Assume;
Cost of each book = a
Find:
Cost of each book
Computation:
Total amount spend = Cost of calendar + Number of books(Cost of each book)
52.50 = 9 + 3(a)
Cost of each book = 14.5

Find the circumference of a 11cm radius circle using pi 3.14
Answer:
69.08 cm
Step-by-step explanation:
circumference= 2πr = 2 × 3.14 × 11 cm
Answer:
69.12 cm
Step-by-step explanation:
C = 2πr
C = 2(3.14)11
C = 6.28(11)
C = 69.12 cm
Part A: Xavier needs to collect at least 120 cans for a food drive to earn community service credit. He has already collected 64 items. Choose the correctly written inequality to represent the number of cans, c, that Xavier must still collect (before solving)
A 64 + c ≥ 120
B 64 + c < 120
C c - 120 ≤ 64
Answer:
A
Step-by-step explanation:
He needs to collect at least 120 so if c is what he must still collect
64 +c must be greater than or equal to 120

The cone and cylinder above have the same radius and height. The volume of the cylinder is 48 cm3. What is the volume of the cone?
A.
24 cm3
B.
16 cm3
C.
96 cm3
D.
144 cm3
Answer:
Option B (16 cm³)
Step-by-step explanation:
GIVEN :-
Both cone and cylinder have same radius and height.Volume of cylinder = 48 cm³TO FIND :-
Volume of coneFACTS TO KNOW BEFORE SOLVING :-
Volume of a cylinder having radius 'r' and height 'h' is [tex]\pi r^{2} h[/tex]Volume of a cone having radius 'r' and height 'h' is [tex]\frac{1}{3} \pi r^{2} h[/tex]Hence ,
Volume of cylinder = Thrice the volume of cone
[OR]
Volume of cone = One third of volume of cylinder
PROCEDURE :-
Volume of cone = [tex]\frac{1}{3} (Volume \: of \: cylinder) = \frac{48}{3} = 16cm^3[/tex]

4x^2+6x-9 if x=3
3y+7(2y-5) if y=4
Answer:
1. 45
2. 33
Explanation:
1. 4x² + 6x - 9
= 4(9) + 18 - 9
= 36 + 18 - 9
= 45
2. 3y + 7(2y - 5)
= 12 + 7(8 - 5)
= 12 + 56 - 35
= 33
i hope this helps! :D
Answer:
45
33
Step-by-step explanation:
4(3)^2+6(3)-9= 36+18-9= 45
3(4)+7(2*4-5)= 12+7(8-5)= 12+7(3)= 33

Answer:
D
Step-by-step explanation:
Hello There!
N = Nickels and D = Dimes
The total amount of nickels and dimes is 27
so d + n = 27
or d = 27 - n
or n = 27 - d
It says that the amount of nickels she has is 3 times the amount of dimes minus 1
so
n = 3d - 1
so looking at the information above we can conclude that the answer is D
Answer:
d
Step-by-step explanation:
Start at 4 3/4 and count on steps of 1/4. If 4 3/4 is the first number in the sequence write down the 3rd number and the 6th number and the 9th number
Answer:
5 1/4 ; 6 ; 6 3/4
Step-by-step explanation:
Using the nth term of an arithmetic progression relation.
an = a + (n - 1)d
First term, a = 4 3/4
Common difference, d = 1/4
3 rd term ; n = 3
a3 = 4 3/4 + (3 - 1)1/4
a3 = 4 3/4 + 2*1/4
a3 = 4 3/4 + 1/2
a3 = 5 1/4
6th term ; n = 6
a6 = 4 3/4 + (6 - 1)1/4
a6 = 4 3/4 + 5*1/4
a6 = 4 3/4 + 5/4
a6 = 6
9 th term ; n = 3
a9 = 4 3/4 + (9 - 1)1/4
a9 = 4 3/4 + 8*1/4
a9 = 4 3/4 + 2
a9 = 6 3/4

Total surface area??
Answer:
total area = 207 cm²
Step-by-step explanation:
base area = 9 x 9 = 81
side area = 1/2(9)(7) = 31.5 x 4 (for 4 sides) = 126
81 + 126 = 207 cm²
The product of two numbers is negative. What conclusion can you draw about the sign of the quotient of the same numbers? *
Answer:
The quotient is negative.
Step-by-step explanation:
The rules of signs for multiplication and division of two numbers are the same.
If you multiply or divide two numbers with the same sign (both positive or both negative), the answer is positive.
If you multiply or divide two numbers with different signs (one positive and one negative), then the answer is negative.
Since the product is negative, then the quotient is also negative.
Answer: The quotient is negative.

Raymond needs to cover the entire surface area of the square based pyramid with paper what is the minimum amount of paper he will need
Answer: 408 sq ft
Step-by-step explanation: You would need to use the surface area formula SA = 1/2LP + B. Note that L is the slant height, P is the perimeter of the base, and B is the area of the base. 11 is the slant height as shown in the image above, p is 48 since you add 12 + 12 + 12 + 12, and the area of the square will be 144 since 12*12 = 144. Once you substitute the numbers in their correct place, you should get SA = 1/2 (11)(48)+144 which gives you 408 sq ft. Hope this helps!

Answer:
B. 14/15
Step-by-step explanation:
I hope this helps.
Answer:
B: 14/15
Step-by-step explanation:
Here's why I say this:
The total is 120. 8 have a box meaning 112 do not have a box. The question is asking about those without a box, so 112 will be used. 112/120. Simply by dividing each the numerator and denominator, in this case by 8. The fraction left is 14/15

Slope intercept form of (2,4) slope is 2
To write slope intercept form from a point, you take the 2 and covert it to 2/1, or rise/run form. Then you find the y-intercept. Now listen, this is very complicated. Ready? It's the y-coordinate. 4. Veery complicated.
So y=2/1+4

63 1/4
Step-by-step explanation:
Given the function y=-\frac{3\sqrt{x^5}}{4},y=− 4 3 x 5 , find \frac{dy}{dx}. dx dy . Express your answer in radical form without using negative exponents, simplifying all fractions.
Given:
The function is:
[tex]y=-\dfrac{3\sqrt{x^5}}{4}[/tex]
To find:
The value of [tex]\dfrac{dy}{dx}[/tex].
Solution:
We have,
[tex]y=-\dfrac{3\sqrt{x^5}}{4}[/tex]
It can be written as
[tex]y=-\dfrac{3}{4}x^{\frac{5}{2}}[/tex] [tex][\because \sqrt[n]x=x^\frac{1}{n}][/tex]
Differentiate with respect to x.
[tex]\dfrac{dy}{dx}=-\dfrac{3}{4}\times \dfrac{5}{2}x^{\frac{5}{2}-1}[/tex] [tex][\because \dfrac{d}{dx}x^n=nx^{n-1}][/tex]
[tex]\dfrac{dy}{dx}=-\dfrac{15}{8}x^{\frac{5-2}{2}}[/tex]
[tex]\dfrac{dy}{dx}=-\dfrac{15}{8}x^{\frac{3}{2}}[/tex]
[tex]\dfrac{dy}{dx}=-\dfrac{15}{8}\sqrt{x^3}[/tex]
Therefore, the value of [tex]\dfrac{dy}{dx}[/tex] is [tex]-\dfrac{15}{8}\sqrt{x^3}[/tex].
