Answer:
512Step-by-step explanation:
The number 512 on prime factorization gives 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2. On combining the prime factors in groups of 3 gives 8. So, the cube root of 512 = ∛(2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2) = 8 (perfect cube).#CaRRyOnLeArNinG
Answer:
512
Step-by-step explanation:
you need to find the value of 8 cubed which is 8^3. All 8^3 means is multiplying 8 three times so 8 × 8 × 8 = 512.

What is the solution of log(2f+4)=log(14-3f)
A)-18
B)-2
C)2
D)10
Answer:
f = 2
Step-by-step explanation:
equate the log
therefore,
2f + 4 = 14 - 3f
collect like terms
2f + 3f = 14 - 4
5f = 10
divide through by 5
f = 10/5
f = 2
if the value of a in the quadratic function f(x) = ax^2 + bx + c is 1/2, the function will:
Answer:
Open up and have a minimum
Step-by-step explanation:
If the x² coefficient is:
Positive, the graph will open up and have a minimum
Negative, the gaph will open down and have a maximum
Answer:
opens up and has a minimum
Step-by-step explanation:
Provided a is not 0, y=ax^2+bx+c will be a parabola.
The parabola will open up and have a minimum if a is positive.
The parabola will open down and have a maximum if a is negative.
Since 1/2 is positive, then your parabola opens up and has a minimum.

Mr.Li bought a memory card for $138.89 including tax.The card had a sticker price of $129.20.What percent sales tax did he pay.
Answer:
7.5%
Step-by-step explanation:
Cost of memory card including tax = $138.89
Cost of memory card only = $129.20.
Cost of tax on memory card = Cost of memory card including tax - Cost of memory card only
= $138.89 - $129.20
= $9.69
Cost of tax on memory card = $9.69
What percent sales tax did he pay.
Percent of tax = Cost of tax on memory card / Cost of memory card only
= $9.69 / $129.20 × 100
= 0.075 × 100
= 7.5%
Percent of tax = 7.5%

The box-and-whisker plot below represents some data set. What percenta data values are less than 66?
Given:
The a box-and-whisker plot if a data set.
To find:
The percentage of data values that are less than 66.
Solution:
From the given box-and-whisker plot, it is clear that the number 66 is the highest value of the data set.
It means all the values of the data set are less than 66 and no value can be more than 66.
All value means 100%.
Therefore, 100% of data values are less than 66.

An electrician needs 3/8 of a roll of electrical wire to wire each room in a house. How many rooms can he wire with 2 1/4 rolls of wire? Write your answer as a fraction or as a whole or mixed number.
Answer: 6 rooms
Step-by-step explanation:
3/8 rolls of wire are needed to wire a room in a house. If there are a total of 2¹/₄ rolls of wires, the number of rooms that could be wired is:
First convert to an improper fraction:
2¹/₄ = 9/4 rolls of wire
Total number of rooms that can be wired are:
= Total amount of wire available / Wires per room
= 9/4 ÷ 3/8
= 9/4 * 8/3
= 72 / 12
= 6 rooms
How many degrees does the hour hand of a clock turn between 3 p.m and 7:30 p.m ?
A clock has 12 hours on it.
360/12 = 30
Each hour is 30 degrees.
3pm to 7:30pm is 4.5 hours
Multiply total hours by degrees per hour:
4.5 x 30 = 135 degrees
Answer:
135 degree
Step-by-step explanation:
difference of 3pm to 7:30 is 4 hrs 30 min
12hrs=360degree
60min=360degree
4×360/12
=120
360/12×60×30
360×30÷720
15
now
120+15
135degree
If [tex]\frac{a+b}{3} =\frac{b+c}{6} =\frac{c+a}{5}[/tex] then prove that: [tex]\frac{a+b+c}{a} =7[/tex]
Answer:
[tex]\dfrac{a+b+c}{a} =7[/tex]
Step-by-step explanation:
Given :-
[tex]\dfrac{a+b}{3} =\dfrac{b+c}{6} =\dfrac{c+a}{5}[/tex]And we need to prove that ,
[tex]\dfrac{a+b+c}{a} =7[/tex]So let us assume that ,
[tex]\dfrac{a+b}{3} =\dfrac{b+c}{6} =\dfrac{c+a}{5}=k[/tex]
Where k is a constant . Now equate each of the three terms separately to k . Therefore we have ,
[tex]\dfrac{a+b}{3}=k[/tex][tex]\implies a + b = 3k \quad \dots (i) [/tex]
Similarly we can say that ,
[tex]\implies c + b = 6k \quad \dots (ii)[/tex]
[tex]\implies a + c = 5k\quad \dots (iii) [/tex]
Subtracting (i) and (ii) :-
[tex]\implies a - c = -3k \quad \dots (iv) [/tex]Adding (iv) and (iii) :-
[tex]\implies 2c = 4k [/tex]
[tex]\implies \boxed{c = 4k }[/tex]
Put this is (ii) :-
[tex]\implies b +4k = 6k [/tex]
[tex]\implies \boxed{b= 2k }[/tex]
Similarly we will get ,
[tex]\implies \boxed{a = k }[/tex]
Proving the given equation :-
[tex]\implies \dfrac{a+b+c}{a} \\\\\implies \dfrac{k+2k+4k}{k} \\\\\implies \dfrac{7k}{k}=\boxed{\red{ 7}}[/tex]
Hence proved !

Xander's adult cat weighs 2,918 grams. As an 8-week old kitten, Xander's cat weighed 640 grams. What is the percent increase in the kitten's weight rounded to the nearest whole number?
Answer:
Percentage increase = 36%
Step-by-step explanation:
Kitten's weight = 640 grams
Adult's weight = 2918 grams
To find the percentage increase in the kitten's weight;
We will calculate the increase using the formula;
[tex] Increase = original \; number - new \; number [/tex]
Substituting the values, we have;
Increase = 2918 - 640 = 2278
Mathematically, percentage increase is calculated using the following formula;
[tex] Percentage \; increase = \frac{increase}{original \; number} * 100[/tex]
[tex] Percentage \; increase = \frac{2278}{640} * 100[/tex]
[tex] Percentage \; increase = 3.56 * 100[/tex]
Percentage increase = 35.5 ≈ 36%

second equation is substituted into the first equation
3x + 2y = -21
x - 3y = 4
3(3y + 4) + 2y = -21
3(-3y + 4) + 2y = -21
3x + 2(3y + 4) = -21
3x + 2(-3y + 4) = -21
Answer:
answer is
3(3y+4) + 2y = -21 .
Jay currently has a balance of $2,375 on her credit card. If she must make a minimum monthly payment of 5.8% of her total balance, what is her minimum payment, to the nearest cent?
Answer:
$137.75
Step-by-step explanation:
question is 'what is 5.8% of 2375'
'what' means assign a variable
'is' means an equal sign
'of' means to multiply
p = .058 x 2375
p = 137.75
*You could do the following: p = 5.8 x 2375 and get 13775 but you have to remember to move the decimal point two places to the left
