The total of Jenny's 5 tests = 375
If she wants an average of 77 then
her 6 tests must total 6 x 77 = 462
462 - 375 = 87 which is what Jenny
must score on the sixth test for an
average of 77.
:-)
Answer:
79
Step-by-step explanation:
Sum of 4 test for Average of 82 must be 82 x 4 which is 328.
Subtract previous 3 scores from 328:
328 - (98 + 83 + 68)
328 - 249 = 79
She needs a 79
Brody has already read 8 books this year before joining a book club,and he plans to read 1 book every month now that he has joined. If Body has read 28 books so far,how many months has he been with his book club?
Answer: 20 months
explanation: You subtract 8 from 28 since 8 is the amount he had before he joined. He also said he planned on reading 1 book per month after joining the club. You want to subtract the 8 since it isn't relevant to the book club books read.
If x varies inversely as y and x=12 when y=9, find x when y=54
Answer:
x = 72
Step-by-step explanation:
We set the two equal to each other
x = 12/y = 9 is equal to x/y = 54.
In order for 9 to get to 54, you have to multiply it by 6. Since you multiplied the denominator with 6, you have to do the same with the numerator. 12 times 6 is 72.
x = 72

What following number is in between 2/5 and 7/8?
15/16, 3/4, 3/8, 1/3
Answer:
Step-by-step explanation:
You need to give all the fractions a common denominator so you can compare the numerators.
The least common multiple of 5, 8, 16, 4, 3 is 240.
⅖ = 96/240
⅞ = 210/240
15/16 = 225/240
¾ = 180/240
⅜ = 90/240
⅓ = 80/240
The only numerator between 96 and 210 is 180.
180/240 = ¾
⅖ < ¾ < ⅞

A raft travels downriver at a rate of 6 miles per hour. The total distance d in mile that the raft travels is equal to the rate times the number of hours h. Dependent Variable: Independent variable: Equation:
Answer:
Dependent variable: total distance (d)
Independent variable: number of hours (h)
Equation: d = 6h
Step-by-step explanation:
In this case given, the dependent variable, total distance (d), is dependent on the independent variable, number of hours (h). This is because, a change in the value of h leads to the change in the value of d. In order words, total distance (d) is a function of the number of hours (h).
Therefore:
Dependent variable: total distance (d)
Independent variable: number of hours (h)
Rate: 6 miles/hr
Equation: d = 6h

simplify the following using L'Hôpital's Rule:
[tex]\displaystyle\lim_{x\to 2}\frac{x^2+x-6}{x^2-4}[/tex]
[tex]\text{note:explanation is a must}[/tex]
Answer:
[tex] \displaystyle \: \frac{5}{4} [/tex]
Step-by-step explanation:
we are given a expression
we are said to solve it using L'Hôpital's Rule
recall, L'Hôpital's Rule:
[tex] \displaystyle \lim _{x \to \: c}( \frac{f(x)}{g(x)} ) = \lim _{x \to \: c} \frac{f ^{'}(x) }{ {g}^{'}(x) } [/tex]
it is to say the ' means derivative
our given expression:
[tex]\displaystyle\lim_{ x\to 2}\frac{x^2+x-6}{x^2-4}[/tex]
let's apply L'Hôpital's Rule
[tex]\displaystyle\lim_{ x\to 2}\frac{ \dfrac{d}{dx} (x^2+x-6)}{ \dfrac{d}{dx} (x^2-4)}[/tex]
some formulas of derivative
[tex] \displaystyle \: \frac{d}{dx} {x}^{n} = {nx}^{n - 1} [/tex]
[tex] \displaystyle \: \frac{d}{dx} {x}^{} = 1[/tex]
[tex] \displaystyle \: \frac{d}{dx} {c}^{} = 0[/tex]
[tex] \sf \displaystyle \: \frac{d}{dx} {f}^{} (x) + {g}^{}(x) = {f}^{'} (x) + {g}^{'}(x)[/tex]
use sum derivative formula to simplify:
[tex]\displaystyle\lim_{ x\to 2}\frac{ \dfrac{d}{dx} (x^2)+ \dfrac{d}{dx} (x) + \dfrac{d}{dx}( -6)}{ \dfrac{d}{dx} (x^2) + \dfrac{d}{dx} (-4)}[/tex]
simplify using exponents using exponent derivative formula:
[tex]\displaystyle\lim_{ x\to 2}\frac{ 2x+ \dfrac{d}{dx} (x) + \dfrac{d}{dx}( -6)}{ 2x + \dfrac{d}{dx} (-4)}[/tex]
use variable derivative formula to simplify variable:
[tex]\displaystyle\lim_{ x\to 2}\frac{ 2x+ 1+ \dfrac{d}{dx}( -6)}{ 2x + \dfrac{d}{dx} (-4)}[/tex]
use constant derivative formula to simplify derivative:
[tex]\displaystyle\lim_{ x\to 2}\frac{ 2x+ 1+ 0}{ 2x + 0}[/tex]
simplify addition:
[tex]\displaystyle\lim_{ x\to 2}\frac{ 2x+ 1}{ 2x }[/tex]
since we are approaching x to 2
we can substitute 2 for x
[tex]\displaystyle\lim_{ x\to 2}\frac{ 2.2+ 1}{ 2.2 }[/tex]
simplify multiplication:
[tex]\displaystyle\frac{ 4+ 1}{ 4}[/tex]
simplify addition:
[tex] \displaystyle \: \frac{5}{4} [/tex]
hence,
[tex]\displaystyle\lim_{ x\to 2}\frac{ \dfrac{d}{dx} (x^2+x-6)}{ \dfrac{d}{dx} (x^2-4)} = \frac{5}{4} [/tex]

Step-by-step explanation:
For this triangle to be a right triangle the following has to happen:
a^2 + b^2 = c^2
a=3, b=9, c= 12
3^2+9^2 does not equal 12^2
9+81 = 90 12^2 = 144
90 does not equal 144 so is not a right triangle
Answer:
see explanation
Step-by-step explanation:
Using converse of Pythagoras' identity
If the square of the longest side is equal to the sum of the squares on the other 2 sides then the triangle is right.
longest side = 12 , then 12² = 144
3² + 9² = 9 + 81 = 90 ≠ 144
Thus the triangle is not right.
a rational number m is called a perfect square if and only if for some positive rational number, m equals

The sum of the ages of mr a and mr z is 65 years. the difference of their ages is 7 years.what are their ages
Answer:
29, and 36
Step-by-step explanation:
65-7= 58
58/2= 29
29+7= 36
Answer:
29 and 36
Step-by-step explanation:
65 split in two since there are 2 people is 32.5
Since there is a 7 year difference, split 7 in half also which is 3.5
Subtract 3.5 from 32.5 to get the younger ones age and and add 3.5 to 32.5 to get the older one's age.
32.5-3.5= 29
32.5+3.5= 36

Answer:
376.99 cm^3 or 120π cm^3
Step-by-step explanation:
The volume of a cone is 1/3(B*h) where B is the base area and h is height.
The base of a cone is a circle.
Area of a circle=πr^2
Area of the circle=π6^2
Area of the circle=36π
Plug it into the formula for the volume:
V=1/3(36π*10)
V=1/3(360π)
V=120π
V=376.99
