Step-by-step explanation:
✦ The pattern is y ÷ 8. (So just divided by 8 each time.)
✧ 512 ÷ 8 = 64
✧ 64 ÷ 8 = 8
✧ 8 ÷ 8 = 1
✧ 1 ÷ 8 = 0.125
✧ 0.125 ÷ 8 = 0.015625
✦ So then the next values would be:
✧ 8⁰ = 1
✧ 8⁻¹ = 0.125
✧ 8⁻² = 0.015625

For every 8 boys signed up for intramural basketball, there are 6 girls. If there are 48 boys signed up to play intramural basketball, how many girls are signed up? 30 girls 33 girls 36 girls 42 girls
Answer:
36 girls signed up
Step-by-step explanation:
1. Create a ratio for boys to girls: 8:6
2. Multiply 8 * 6 to get 48 (amount of boys who signed up.)
Whatever we do one on side we do to the other, so multiply the girls by 6.
6 * 6 = 36
48:36 = 8:6

A silo is a building shaped like a cylinder used to store grain. The diameter of a particular silo is 6.5 meters, and the height of the silo is 12 meters.
Hey there! I'm happy to help!
To find the volume of a cylinder, you multiply the base by the height.
First, we find the base. The base is a circle. To find the area of a circle, you square the radius and multiply it by pi (we will use 3.14). The radius is half the diameter.
6.5/2=3.25
We square this.
3.25²=10.5625
And multiply by 3.14
10.5625(3.14)=33.16625
Now we multiply this by the height.
33.16625(12)=397.995
Therefore, the volume of this silo is 397.995 cubic meters.

Using the online regression calculator :
The obtained regression equation is :
ŷ = 3.79X + 2185.47
Comparing the obtained result with the general form of the equation:
y = mx + c
Where m = gradient or slope whose value gives the variation in cost per rental return (x)
c = intercept, which is constant or fixed, it is the value where the regression line crosses the y axis, hence, it corresponds to the fixed cost.
Hence,
The variable cost per rental return(m)
mx = 3.79x
m = $3.79
The fixed cost :
c = $2185.47

Given :
A sequence of numbers begins at 400.
To Find :
If the pattern increases by consecutive multiples of 5 starting with 5, then find the next 3 numbers in the sequence 400, ___, ___, ___ .
Solution :
This is the a question of arithmetic progression .
The first term is , a = 400 .
Now , it is given that the next numbers increase by the multiples of 5 starting with 5 .
So , common difference is , d = 5 .
Now , we know , [tex]n^{th}[/tex] number in A.P is given by :
[tex]a_n=a+(n-1)d[/tex]
Putting value of n = 2 , 3 , 4 .
We get :
[tex]a_2=a+(2-1)d=400+5=405\\\\a_3=a+(3-1)d = 400 + (5\times 2) = 410\\\\a_4=a+(4-1)d = 400 +(5\times 3)=415[/tex]
Therefore , the next 3 numbers in the sequence is 400 , 405 , 410 , 415 .
Hence , this is the required solution .

If you were 10 years old on
Earth, you would be 41.494 years old
on Mercury. Write the age on Mercury
as a mixed number in simplest form.
Answer:
[tex]41\frac{247}{500}[/tex]
Step-by-step explanation:
41.494
= [tex]41\frac{494}{1000}[/tex]
to simplify the fraction 494 /1000, we have to find and divide both numerator and denominator by the their highest common factor
494 = 2 x 13 x 19
1000 = 2 x 2 x 2 x 5 x 5 x 5
comparing the two, we can see that that the only common factor that both numbers share is 2, hence we divide both numerator and denominator by 2
41 494/1000
= [tex]41\frac{494}{1000}[/tex]
= [tex]41\frac{494/2}{1000/2}[/tex]
= [tex]41\frac{247}{500}[/tex]

A rectangle has a length of 12 yards less than 10 times it’s width. If the area of the rectangle is 880 yards
Answer: The length is 88 yards and the width is 10 yards. Look into the steps for more information.
Step-by-step explanation:
The length is 12 yards less than 10 times the width so we can represent that by the equation L = 10w - 12
And the area is 880 so the width times the length has to equal 880. the width is w and the length is 10w -12
w( 10w -12 ) = 880 solve for w
10w^2 - 12w = 880 subtract 880 from both sides
-880 -880
10w^2 - 12w - 880 = 0 They share the same factors so dive each side by 2
5w^2 - 6w^2 - 440 = 0
a= 5 b = -6 and c=-440
The quadratic formula says that x= -b ± [tex]\sqrt{b^2- 4ac} / 2a[/tex]
x= 6 ±[tex]\sqrt{8836} / 5[/tex]
x= 6 ± 94 /10
x= 100 /10
x = 10
In this case the width is 10 yards.
The length is 12 less than 10 times the width .
So L = 10(10) - 12
L = 100- 12
l = 88
So the length is 88
The required length and width are 229 and 27 yards.
It is required to find the dimension of rectangle.
What is rectangle?A rectangle is a type of quadrilateral, whose opposite sides are equal and parallel. It is a four-sided polygon that has four angles, equal to 90 degrees. A rectangle is a two-dimensional shape.
Given:
A=l*w
w=width
10w-12=length
According to given question we have,
6183=(10w-12)(w)
6183=10[tex]w^{2}[/tex]-14w
9[tex]w^{2}[/tex]-14w-6183=0
By simplify we get,
(9w+229)(w-27)=0
w-27=0
w=27 yards
l=9*27-14=229 yards
Therefore, the required length and width are 229 and 27 yards.

Write an equation of a line perpendicular to
y = 2/7x - 5 through (2, -3)
Hi there! :)
Answer:
[tex]\huge\boxed{y = -7/2x + 4}[/tex]
Given equation:
y = 2/7x - 5
A perpendicular line will have a slope that is the opposite reciprocal, therefore:
2/7 --> -7/2
Substitute the x and y coordinates of the point given to write an equation in slope-intercept form:
(-3) = -7/2(2) + b
Simplify:
-3 = -7 + b
-3 + 7 = b
b = 4
Rewrite the equation:
y = -7/2x + 4

The graph of the line 4x+3y= 12 is translated right 1 unit and down 3 units. What is the equation of the new line?
Answer: y = 7/3 - (4/3)*x
Step-by-step explanation:
First, let's write our line in the notation:
y = f(x)
So we must isolate y in the equation:
4x + 3y = 12
3y = 12 - 4x
y = 12/3 - (4/3)*x = 4 - (4/3)*x
Now, we have two translations, one horizontal and one vertical.
Let's define them in general cases:
Horizontal translation.
When we have y = f(x) and we want to do a horizontal translation of A units to the right (A positive) we have:
y = g(x) = f(x - A)
So we replace our variable x by x - A.
Vertical translation.
When we have y = f(x) and we want to do a horizontal translation of A units up (A positive) we have:
y = g(x) = f(x) + A.
Then in this case we have:
y = f(x) = 4 - (4/3)*x
then, the horizontal translation of 1 unit to the right is:
y = f(x - 1) = 4 - (4/3)*(x - 1)
And the translation of 3 units down (a vertical translation) is:
y = f(x - 1) - 3 = 4 - (4/3)*(x - 1) - 3 = 1 + 4/3 - (4/3)*x
y = 7/3 - (4/3)*x
This equation represents the new line.

Benn Cornell and Tom Ingulli drove to Chicago a distance of 510 miles, their car gets 23 miles per gallon of gasoline. gasoline costs them $2.59 per gallon. how much did they spend for gasoline on there trip?
Answer:
about $57.42
Step-by-step explanation:
we know how many miles they drove in all (510) and how many miles they can drive per gallon (23)
we need to find out how many gallons of gas they used by dividing the total number of miles they drove (510) by the number of miles per gallon (23) which is about 22.17
510 ÷ 23 = 22.17
we then need to find out how much money they spent on the total number of gallons of gas they purchased by multiplying 22.17 by the amount of money for one gallon of gas ($2.59)
22.17 × 2.59 = $57.42

Answer:
B. 7Step-by-step explanation:
The question lacks the required diagram. Find the diagram attached.
From the diagram it can be seen that the line is parallel to the y axis, hence we are going to locate each endpoints on the y axis.
The lower end point is on 2units while the upper end point is on 9 units both on the y axis. The distance between this two points will be the difference between the end point values i.e 9-2 = 7 units.
Hence the distance between the two points shown is 7 units
