Answer:
y= 80/9
Step-by-step explanation:
Given
" y varies directly as x" and "as the square of z" so y = x* z²* some number
if y =25/9 when x= 5, z= 1 and y = x*z²* some number
then 25/9 = 5 * 1² * some number
5*(5/9) = 5 * some number
therefore y = x* z²* (5/9)
y= ? when x=1 , z= 4
y = x * z² * (5/9)
y = 1 * 4² * (5/9)
y = 16*5 / 9
y = 80/9
What is the area of a square that has a side of 4 units
Answer:16
Step-by-step explanation: So we know that a square has 4 equal sides, and if one of the sides is 4, then that means all sides were 4. Are is side * side. so the area is 4*4 wich is 16!
Answer:
16
Step-by-step explanation:
Square formula: side²
So 4²=16

Find the surface area and volume of the basketball. Round your answer to the nearest hundredth.
Answer:
Surface area: 277.59 in^2
Volume: 434.89 in^3
Step-by-step explanation:
Radius = C/(2*pi)
29.5/3.14 = 9.39
Radius = 9.39/2 = 4.7 in
A = 4 pi r^2
A = (4) (3.14) (4.7)^2
A = 277.59 in^2
Volume = (4/3) (pi)(r)^3
(4/3)(3.14)(4.7)^3
= 434.89 in^3
Answer:
Surface area: [tex]277.59[/tex] in^[tex]2[/tex]
Volume: [tex]434.89[/tex] in^[tex]3[/tex]
Explanation:
Radius = C/([tex]2[/tex]*[tex]Pi[/tex])
[tex]29.5/3.14[/tex] = [tex]9.39[/tex]
Radius = [tex]9.39/2[/tex] = [tex]4.7[/tex] in
A = [tex]4[/tex] [tex]Pi[/tex] r^[tex]2[/tex]
A = ([tex]4[/tex]) ([tex]3.14[/tex]) ([tex]4.7[/tex])^[tex]2[/tex]
A = [tex]277.59[/tex]in^[tex]2[/tex]

what is the slope of the line that passes through the points 6,10 and -4,4
Answer:
Slope = 3/5
Step-by-step explanation:
Slope = (change in y) / (change in x)
= (4 - 10)/(-4 -6)
= -6/-10
= 3/5
Find the shaded region
maybe -10.8 cuz it looks like u gotta multiply by 10 to get the full shape
Write the equation of the line parallel to the line and passing through the point.
Chapter Reference
d
y=x+5, (8, 1)
Answer:
y = x - 7
Step-by-step explanation:
Parallel lines have the same gradient in this case 1 is the gradient.
Using the point (8,1) we can form our own equation.
1 will be y, 1 will be m, 8 will be x
All we have to do is find C in order to form the equation y=mx+c
1 = 1(8) + c
1 = 8 + c
C = - 7
Therefore;
y = x - 7

Answer:
Step-by-step explanation:
you just gotta add all the side-lengths together and consider each grid square as 10 instead of 1.
so 70 + 40 + 20 + 60 + 20 + 40 i believe.
this all equals 250.
ask your teacher if its a type, because there's no 250 on there. grab a calculator or something as proof.
Write the equation of the graph in slope-intercept form (y = mx + b)
Answer:
y = -3x + 4
Step-by-step explanation:
To find the slope, use rise over run with two points. The first point (0,4) to the second point (-2,-2) is 6 units down and 2 units to the right, so you can set up a fraction to solve for the slope:
-6/2 = -3
To find the y-intercept,find the point where the x-value is 0. That point is (0,4),so the y-intercept is 4.
mx represents the slope, so mx is -3x and b is the y-intercept, so that value is 4.
Answer:
y = -3x + 4
Step-by-step explanation:
m = the slope (rise/run)
b = y-intercept
we can see that the rise is 6 (based on the two points) and the run is 2 (based on the labeled points)
- that means that m = 6/2 or m = 3
y = 0 when x = 4, so the y-intercept is 4, or b = 4
put it together!
y = 3x +b
BUT WAIT!!
- the line is decreasing which means that your equation should be negative, so put a negative symbol before 3x.
- why? the rise is decreasing!
final equation --------> y = -3x + 4

how do i calculate slope?
Answer:
In order to calculate the slope, you'll need 2 ordered pairs (x, y).
The formula for calculating the slope is:
[tex]m = \frac{y2 - y1}{x2 - x1}[/tex]
where m = slope
(x1, y1) = first ordered pair
(x2, y2) = second ordered pair
Regardless of which values for the (x1, y1) and (x2, y2) you choose, you would still end up with the same slope (as long as it's done correctly).
As an example, let's say you have the following set of points:
(2, 4) (8, 1)
Let (x1, y1) = (2, 4)
(x2, y2) = (8, 1)
Plug these values into the slope formula:
[tex]m = \frac{y2 - y1}{x2 - x1}[/tex]
[tex]m = \frac{1 - 4}{8 - 2} = \frac{-3}{6} = -\frac{1}{2}[/tex]
Therefore, the slope of the line is - 1/2.
To prove that you'll end up with the same value for the slope:
This time, let (x1, y1) = (8, 1)
(x2, y2) = (2, 4)
[tex]m = \frac{y2 - y1}{x2 - x1}[/tex]
[tex]m = \frac{4 - 1}{2 - 8} = \frac{3}{-6} = - \frac{1}{2}[/tex]
Therefore, the value of the slope is still -1/2.

18. You have no more than $60 to spend. You want a drink that costs $1.50 including tax, and you want to buy a
pair of pants, which will have 4% sales tax.
a.) What is the inequality that represents the amount of money you have to spend?
b.) Given that you can spend no more than $60, what is the most a pair of pants could cost?
Answer:
a. pants + tax + drink ≤ 60 b. $56.16
Step-by-step explanation:
60-1.5 = 58.5 = money left for pants+tax
58.5/100 = 0.585 = 1%
0.585x 4= $2.34 = highest possible tax
58.5 - 2.34 = $56.16 most
pants + tax + drink ≤ 60

find the perimeter of rectangle.
Answer:
it depends on how big the rectangle is though...
Step-by-step explanation:
Answer:
6x + 10
Step-by-step explanation:
Given,
Length ( l ) = 3x
Breadth ( b ) = 5
To find : Perimeter of the rectangle = ?
Formula : -
Perimeter of the rectangle = 2 ( l + b )
Perimeter of the rectangle
= 2 ( 3x + 5 )
= 2 ( 3x ) + 2 ( 5 )
= 6x + 10

hope it will help u
Answer:
91.2 secondsStep-by-step explanation:
5 m = 4 second
1 m = 4/5 second
1 m = 0.8 second
∴ 114 m = 114 x 0.8
= 91.2 seconds.

2. Mary answered 6 questions correctly on her Biology test.
She answered 20% of the questions correctly. In total, how
many questions were on the Biology test?
Answer:
60
Step-by-step explanation:
if 6 questions is 20 percent, that means every 3 questions should be 10 percent. 60÷3=20
Answer:
The Answer is 30 questions in total.
Step-by-step explanation:
1. The first thing you would want to do is to break down this question.
For every 6 questions, this is 20% of the test done.
2. You now would want to divide 100% (the full amount on the test) by 20%.
100%/20% = 5
3. Now, multiply both to get your answer.
6·5= 30
20%x5= 100%.
Therefore, the total amount of questions on the test is 30 questions.
