Answer:
y = 7.75x
Step-by-step explanation:
Steven earns extra money babysitting.
Step 1
Let us find the amount he earns per hour based on the charges given in the question.
a) He charges $31.00 for 4 hours
4 hours = $31
1 hour = x
Cross Multiply
4x = $31
x = $31/4
x = $7.75
b) And $46.50 for 6 hours.
6 hours = $46.50
1 hour = x
Cross Multiply
6x = $46.50
x = $46.50/6
x = $7.75
This means, Steven earns $7.75 per hour.
Step 2
Let
x represent the number of hours Steven babysit
y represent the amount he charges.
Therefore, an equation to represent the relationship is written as:
y = $7.75 × x
y = 7.75x

find the slope of the line that passes through (23,-3) and (81,91)
Answer: m = 94 / 58 = 47 / 29 = 1.62069
Step-by-step explanation:
Answer:
47/29
Step-by-step explanation:
To find the slope between two points
m = ( y2-y1)/(x2-x1)
= ( 91- -3)/(81 - 23)
= ( 91+3)/(81 - 23)
= 94/58
= 47/29
What is the measure of S?
Answer:
Step-by-step explanation:
90+42 angle S=180 degree(being sum of interior angles of a triangle)
132 angle S=180
angle S=180-132
angle S=48 degree
A bag contains 4 red, 2 blue, 6 green and 8 white marbles. What is the probability of selecting a green marble, replacing it, then selecting a red marble
Answer:
14.7%
Step-by-step explanation:
Being that there is 4 red, 2 blue, 6 green, 8 white, that means there is 20 marbles, with 8 success, 8/20. Since the marble is not replaced, that drops it to 7/19 for the second pull. Multiply these together and you get 14.7%.
(8/20)*(7/19)=.147
.147*100=14.7

Find the volume of the rectangular prism. 4.5 cm 2.5 cm 3 cm
Answer:
33.75 [tex]cm^{2}[/tex]
Step-by-step explanation:
The formula for a rectangular prism is [tex]l*w*h[/tex] where l is the length, w is width, and h is height. So, to solve plug in the given sides to get, 2.5*3*4.5. This equals 33.75 [tex]cm^{2}[/tex].

find the area of a circle with a diameter of 102 in
The area of a circle is the radius squared x pi.
Area = r^2 x pi
R is the radius which is half the diameter.
Diameter = 102 inches
Radius = 102/2 = 51 inches
Area = 51^2 x pi
Area = 2,601pi inches^2 ( in terms of pi) or
Area = 8,167.14 inches^2
Area of circle is 8,167.14 cm ²
Step-by-step explanation:We have
diameter of circle = 102 cm
And we need to find area of circle,
So the formula we using is
Area of circle = π ×r ²
Here,
R denotes for Radius
π denotes for pi.
For finding area of circle we need to find radius
here we have diameter of circle = 102 cm and
We know that ,diameter is the double of radius it means radius is the half of diameter
So, radius of circle = 102/2 = 51 cm
Now Solve it
Area of circle = π × ( r ) ²
Substitute the value
Area of circle = 3.14 × ( 51cm )² .. [ using π = 3.14 ]
Multiply the values
Area of circle = 3.14 × ( 51 cm × 51cm) ..[( 51 ) ²= 51 × 51]
Area of circle = 3.14 × 2,601 cm².
Therefore , Area of circle is 8,167.14 cm ²

y=9x+17
y=x+49
Answer:
y = 10x + 66
Step-by-step explanation:
I don't know if this is how you wanted me to do it, there was not enough information for me to conclude if this was the correct way to do it. but I added 9x + x and whenever there is a variable without a number in front of it the variable = 1x or whatever the variable is. So 9x + 1x= 10x and 17+49= 66 so put it together and you get y= 10x +66
Answer:
y-9x=17-----1
y-x. =49----2
2-1
y-x-(y-9x)=49-17
y-x-y+9x.= 32
8x =32
x=4
y=4+49
=53
x=4
y=53

find the length of the diagonals of rectangle QRST
Answer:
11. 26
12. 111
Step-by-step explanation:
_____________
Answer:
11:
since diagonal are equal of rectangle
QS=RT
4x+6=6x-4
6+4=6x-4x
2x=10
x=10/2
x=5
now
diagonal :4x+6=4*5+6=26
12.
again
QS=RT
9x+12=11x-10
12+10=11x-9x
2x=22
x=11
now
diagonal=9*11+12=99+12=111

A submarine, located at point S, was hidden at a secret place on a coordinate plane before it
moved to its current position. The movement of the submarine is described by the translation x,y→x+4,y-6.
Answer:
The submarine moves 4 units right and 6 units down to get to its current position
Step-by-step explanation:
Given
[tex](x,y) \to (x + 4, y - 6)[/tex]
Required
Describe the movement of the submarine from the initial to the current position
The rule of translation is as follows:
[tex]x \to x + a[/tex] --- This implies right translation by a units
[tex]y \to y -b[/tex] --- This implies down translation by b units
So, we have:
[tex]x \to x + a[/tex]
[tex]x \to x + 4[/tex]
By comparison;
[tex]a =4[/tex]
[tex]y \to y -b[/tex]
[tex]y \to y - 6[/tex]
By comparison:
[tex]b = 6[/tex]
Hence, the submarine moves 4 units right and 6 units down to get to its current position
Two complex numbers are represented by c + d[tex]i[/tex] and e-f[tex]i[/tex] , where c, d, e, and f are positive real numbers. In what two quadrants may the product of these complex numbers lie? Explain your answer in complete sentences.
Answers: First Quadrant and Fourth Quadrant
======================================================
Explanation:
Let
w = c + diz = e - fibe the two complex numbers.
Multiply them out to see what we get
[tex]w*z = (c+di)(e-fi)\\\\w*z = c(e-fi)+di(e-fi)\\\\w*z = ce-cf*i+de*i-df*i^2\\\\w*z = ce-cf*i+de*i-df*(-1)\\\\w*z = ce-cf*i+de*i+df\\\\w*z = (ce+df)+(-cf+de)*i\\\\[/tex]
The result we get is in the form a+bi where
a = ce+df = real partb = -cf+de = imaginary partRecall that any complex number of the form a+bi can be plotted on the xy plane with 'a' being treated as the x coordinate and b as the y coordinate. In short, the location of a+bi is at the point (a,b)
With c,d,e,f being positive, this means ce and df are positive, and a = ce+df is also positive.
This places the result of wz in either the first or fourth quadrants (the northeast or southeast quadrants respectively), due to the positive x coordinate.
We don't have enough info to determine whether b = -cf+de is positive or not. So that's why we can't nail down the precise quadrant of wz
If b > 0, then wz is in quadrant 1
If b < 0, then wz is in quadrant 4

Compute the mean score of these students The following data set are the quiz scores for 14 students. . 76,66,55,80,80,72,97,70,80,72,88,50,63,76
Answer:
73.214285714285714285714285714286 (or 73 rounded down)
Step-by-step explanation:
76, 66, 55, 80, 80, 72, 97, 70, 80, 72, 88, 50, 63, 76
76 + 66 + 55 + 80 + 80 + 72 + 97 + 70 + 80 + 72 + 88 + 50 + 63 + 76 = 1025
1025/14 = 73.214285714285714285714285714286
73.214285714285714285714285714286 ≅ 73
