Answer:
w = 6 x = 5.6
Step-by-step explanation:
w/8 = 7.5/10
10w = 8 (7.5)
10w = 60
w = 6
x/7.5 = 4.5/6
6x = 7.5 (4.5)
6x = 33.75
x = 5.625

The circle below is centered at the point (8, 4) and has a radius of length 4. What is its equation?
Answers
Answer:
(x-8)^2 + (y-4)^2 = 16
Step-by-step explanation:
Standard equation of a circle is expressed as;
(x-a)^2 + (y-b)^2 = r^2
(a, b) is the centre
r is the radius
Given
Centre (8, 4)
r = 4
Substitute
(x-8)^2 + (y-4)^2 = 4^2
(x-8)^2 + (y-4)^2 = 16
This gives the required equation
Answer:
(x-8)^2 + (y-4)^2 = 16

The coach of a softball team has 8 good hitters and 9 poor hitters. He chooses 5 hitters at random.In how many ways can he choose 4 good hitters and 1 poor hitter?
Answers
Answer:
He can choose 4 good hitters and 1 poor hitter in 630 different ways.
Step-by-step explanation:
The order in which the hitters are chosen is not important, which means that the combinations formula is used to solve this question.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
In how many ways can he choose 4 good hitters and 1 poor hitter?
4 good hitters from a set of 8.
1 poor hitter from a set of 9. So
[tex]T = C_{8,4}*C_{9,1} = \frac{8!}{4!(8-4)!}*9 = 630[/tex]
He can choose 4 good hitters and 1 poor hitter in 630 different ways.

graph the line whose y-intercept is -7 and whose x-intercept is 1
Answers
Answer:
[tex]y=7x -7[/tex]
Step-by-step explanation:
We are given two points, the y - intercept and the x - intercept.
The y - intercept being: ( 0, -7 )
The x - intercept being: ( 1, 0 )
The equation of a line in slope - intercept form is:
y = mx + b, where m is the slope and b is the y - intercept.
We already have the y - intercept. So far we have:
y = mx - 7
What we're missing is the slope.
To find the slope, we can use this formula:
[tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex], where [tex]x_{2}[/tex] and [tex]x_{1}[/tex] are the x - coordinates of both points and [tex]y_{2}[/tex] and [tex]x_{1}[/tex] are the y - coordinates of both points.
[tex]m=\frac{0-(-7)}{1-0} \\\\m=\frac{7}{1}\\m=7[/tex]
We now have the missing piece, the slope, so the equation now is:
[tex]y=7x -7[/tex]

If x = 5 units, y = 6 units, and h = 6 units, find the area of the trapezoid shown above using decomposition. A. 102 square units B. 30 square units C. 66 square units D. 48 square units
Answers
Answer:
C. 66 square units
Step-by-step explanation:
The area of the middle rectangle would by base × height, or y × h, or 6 × 6.
The area is 36.
The area for one triangle would 1/2 × base × height.
(But since there are two triangles to solve for, the 1/2 is not necessary, and we can just do base × height again.)
So, it would be x × h, or 5 × 6.
The area is 30.
Combine both areas to get the whole area of 66 units²

The scale factor of the dimensions of two similar wood floors is 4:3. It costs $207 to refinish the smaller wood floor. At that rate, how much would it cost to refinish the larger wood floor? $
Answers
Answer:
$276
Step-by-step explanation:
Create a proportion where x is the cost to refinish the larger wood floor:
[tex]\frac{4}{3}[/tex] = [tex]\frac{x}{207}[/tex]
Cross multiply and solve for x:
3x = 828
x = 276
