Answer:
[tex]\frac{1}{r^{10} }[/tex]
Step-by-step explanation:
Using the rule of exponents
[tex]\frac{a^{m} }{a^{n} }[/tex] ( with n > m )
= [tex]\frac{1}{a^{(n-m)} }[/tex]
Then
[tex]\frac{r^{2} }{r^{12} }[/tex]
= [tex]\frac{1}{r^{(12-2)} }[/tex]
= [tex]\frac{1}{r^{10} }[/tex]

Answers
Step-by-step explanation:
(x + 8) / (5x - 1) > 0
Multiply both sides by (5x - 1)², which is always positive for all real values of x in the domain.
(x ≠ 1/5)
=> (x + 8)(5x - 1) > 0
=> x < -8 or x > 1/5.
The answer is the 2nd option.

Answer:
50 is the answer to this question
Answer:
50
Step-by-step explanation:
Well, you're having trouble with how it's supposed to be 50 right? So I suggest breaking it down a little bit.
As you see:
1100 ÷ 22
1100 and 22 are both divisible by 2 so if we divide both numbers by 2 you get:
550 ÷ 11
now try solving from there!!
If you still don't get it here:
firstly 11 goes into 5 zero times so put nothing
next does 11 go into 55? Yes! it does so how many times does it go into 55?
well let's see: 11 + 11 + 11 + 11 + 11 = 55
now if we count how many 11s there are there is 5! so then you put:
5_
now lets see the next number is 0 and does 11 go into 0? Nope! so we just put:
50 and that is your answer!!

The height of the cuboid is 6 cm.
The volume of the cuboid is 90 cm'.
What is the area of the shaded face?
Answers
Answer:
[tex]A=15\ cm^2[/tex]
Step-by-step explanation:
Given that,
The height of the cuboid = 6 cm
The volume of the cuboid = 90 cm²
We need to find the area of the shaded face.
The volume of a cuboid is given by the formula as follows :
[tex]V=A\times h[/tex]
A is area of the shaded face
Putting all the values,
[tex]A=\dfrac{V}{h}\\\\A=\dfrac{90}{6}\\\\A=15\ cm^2[/tex]
So, the area of the shaded face is [tex]15\ cm^2[/tex].

The ratio of the measures of the three angles of a triangle is 4:5:9. Find the measure of the largest angle of the triangle.
Answers
Answer:
[tex]90^{\circ}[/tex]
Step-by-step explanation:
The interior angles of all triangles sum up to [tex]180^{\circ}[/tex]. Therefore, we can write the following equation:
[tex]4x+5x+9x=180[/tex], where [tex]x[/tex] is some constant.
Combining like terms, we have [tex]18x=180,\: x=10[/tex].
Therefore, the angles of this triangle are [tex]4(10)=40^{\circ}, \: 5(10)=50^{\circ}, \: 9(10)=90^{\circ}[/tex], the largest of them being [tex]\fbox{$90^{\circ}$}[/tex].

Gavin is saving up to buy a new phone.
He already has $100 and can save an additional $7 per week using money from his after-school job
Let us assume that he worked for 'w' weeks
The amount earned for 'w' weeks = 100 + 7w
Hence, the required expression is 100 + 7w
The total amount saved in 10 weeks = 100 + 7(10) = $ 170
Therefore,

If an object is propelled upward from a height of 48 feet at an initial velocity of 96 feet per second, then its height after t seconds is given by the equation h(t)= -16t2+96t +48, where height is in feet. After how many seconds will the object reach a height of 192 feet?
Answers
Answer:
the number of seconds to reach the height is 3 seconds
Step-by-step explanation:
The computation of the seconds that reach the height is as follows;
Given that
h = -16t^2 + 96t + 48
here
H = 192 feet
So,
192 = -16t^2 + 96t + 48
-16t^2 + 96t - 144 = 0
Divide by -16
t^2 - 6t + 9 = 0
t^2 - 3t - 3t + 9
t(t - 3) - 3(t - 3)
t = 3 seconds
Hence, the number of seconds to reach the height is 3 seconds

In 7th grade, the ratio of boys to girls is 6 to 7. If there are 143 students in 7th grade, how many are girls? Do NOT write a label. Just write the number.
Answers
Answer:
123 if your going to the nearest whole number
Step-by-step explanation:
Since
6 : 7 = X : 143
Then we know
6/7 = X/143
Multiplying both sides by 143 cancels on the right
143 × (6/7) = (X/143) × 143
143 × (6/7) = X
Then solving for X
X = 143 × (6/7)
X = 122.57142857143
Therefore
6 : 7 = 122.57142857143 : 143
