so first we need to find the total number of crayons
to do that we're going to multiply 6 by 24 cause each box has 24 crayons
24 × 6 = 144
so the answer of total number of crayons is 144 crayons
next we're going to find the total number of paint brushes
to do that we're going to multiply 9 by 15 cause each package has 15 paint brushes
9 × 15 = 135
so the answer of total number of paint brushes is 135 crayons
finally we're going to calculate the difference
so its 144 crayons subtracted by 135 paint brushes
144 - 135 = 9
so the difference of total number of crayons and total number of paint brushes is 9
hope that helped :))
The difference between the crayons and the paintbrush the total. I just see which one is greater

Use the general slicing method to find the volume of the following solid. The solid whose base is the region bounded by the curve y=38cosx and the x-axis on − π 2, π 2, and whose cross sections through the solid perpendicular to the x-axis are isosceles right triangles with a horizontal leg in the xy-plane and a vertical leg above the x-axis. A coordinate system has an unlabeled x-axis and an unlabeled y-axis. A curve on the x y-plane labeled y equals 38 StartRoot cosine x EndRoot starts on the negative x-axis, rises at a decreasing rate to the positive y-axis, and falls at an increasing rate to the positive x-axis. The region below the curve and above the x-axis is shaded. A right triangle extends from the x y-plane, where one leg is on the x y-plane from the x-axis to the curve and is perpendicular to the x-axis, and the second leg is above the x-axis and is perpendicular to the x y-plane. y=38cosx
Answer:
The volume of the solid = 1444
Step-by-step explanation:
Given that:
The region of the solid is bounded by the curves [tex]y = 38 \sqrt{cos \ x}[/tex] and the axis on [tex][-\dfrac{\pi}{2}, \dfrac{\pi}{2}][/tex]
using the slicing method
Let say the solid object extends from a to b and the cross-section of the solid perpendicular to the x-axis has an area expressed by function A.
Then, the volume of the solid is ;
[tex]V = \int ^b_a \ A(x) \ dx[/tex]
However, each perpendicular slice is an isosceles leg on the xy-plane and vertical leg above the x-axis
Then, the area of the perpendicular slice at a point [tex]x \ \epsilon \ [-\dfrac{\pi}{2},\dfrac{\pi}{2}][/tex] is:
[tex]A(x) =\dfrac{1}{2} \times b \times h[/tex]
[tex]A(x) =\dfrac{1}{2} \times(38 \sqrt{cos \ x})^2[/tex]
[tex]A(x) =\dfrac{1444}{2} \ cos \ x[/tex]
[tex]A(x) =722 \ cos \ x[/tex]
Applying the general slicing method ;
[tex]V = \int ^b_a \ A(x) \ dx \\ \\ V = \int ^{\dfrac{\pi}{2} }_{-\dfrac{\pi}{2}} (722 \ cos x) \ dx \\ \\ V = 722 \int ^{\dfrac{\pi}{2}}_{-\dfrac{\pi}{2}} cosx \dx[/tex]
[tex]V = 722 [ sin \ x ] ^{\dfrac{\pi}{2}}_{-\dfrac{\pi}{2}}[/tex]
[tex]V = 722 [sin \dfrac{\pi}{2} - sin (-\dfrac{\pi}{2})][/tex]
[tex]V = 722 [sin \dfrac{\pi}{2} + sin \dfrac{\pi}{2})][/tex]
[tex]V = 722 [1+1][/tex]
[tex]V = 722 [2][/tex]
V = 1444
∴ The volume of the solid = 1444
One number is 28 less than another number. If the sum of the two numbers is 92, find the two numbers.
Answer:
The two numbers are 32 and 60.
Step-by-step explanation:
We can create two simultaneous equations to solve this problem using the information given in the question.
Let number 1 = x
Let number 1 = y
x = y - 28 -> ( 1 )
x + y = 92 -> ( 2 )
We can solve simultaneous equations using substitution or elimination. For this question, we will use substitution as it is the easier option.
Substitute ( 1 ) into ( 2 ):
x + y = 92 -> ( 2 )
( y - 28 ) + y = 92
2y - 28 = 92
2y = 120
y = 120 / 2
y = 60 -> ( 3 )
Substitute ( 3 ) into ( 1 ):
x = y - 28 -> ( 1 )
x = ( 60 ) - 28
x = 32
Therefore:
x = 32 , y = 60

Sue weighed 82 kg at the start of the year, but she has lost weight at a consistent rate because she has been diligent with her exercise and diet plan. Sue weighed herself at the end of each month and tracked her progress for the full year using the graph above. How much weight did Sue lose each month? Question 5 options: A) 4 kg B) 2 kg C) 3 kg D) 1 kg
Answer:
Option (B)
Step-by-step explanation:
Sue's weight at the start of the year = 82 kg
Sue weighed herself at the end of every year, so that the straight line on the graph shows the gradual reduction in the weight every month.
Slope of the line will describe the reduction in the weight per month.
Let the two points on the given line are (1, 80) and (11, 60).
Slope of the line will be,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
= [tex]\frac{60-80}{11-1}[/tex]
= -2 kg per month
(Here minus sign denotes the reduction of weight per month)
Option (B) will be the answer.
Answer:
2 kg

Point a is at (2,-8) and point c is at (-4,7). Find the coordinates of point b on ac such that the ratio of ab to bc is 2:1
Answer:(-2,2)
Step-by-step explanation:
Point S is on line segment RT. Given ST = 3x
= 3x – 8, RT = 4x, and
RS = 4x 7, determine the numerical length of RT.
Answer:
RT = 20
Step-by-step explanation:
Given that,
Point S lies on the line segment RT.
We have, ST = 3x-8, RT = 4x and RS = 4x-7
It is clear that, RT = RS+ST
Putting the values, we get :
4x = 4x-7 + 3x-8
Taking like terms together,
4x-4x-3x = -7-8
-3x = -15
x = 5
Put the value of x in RT = 4x.
So,
RT = 4(5)
RT = 20
Hence, length of RT = 20.

If the probability that your DVD player breaks down before the extended warranty expires is 0.034, what is the probability that the player will not break down before the warranty expires
Answer:
0.966
Step-by-step explanation:
Given that:
Probability of DVD player breaking down before the warranty expires = 0.034
To find:
The probability that the player will not break down before the warranty expires = ?
Solution:
Here, The two events are:
1. The DVD player breaks down before the warranty gets expired.
2. The DVD player breaks down after the warranty gets expired
In other words, the 2nd event can be stated as:
The DVD does not break down before the warranty gets expired.
The two events here, have nothing in common i.e. they are mutually exclusive events.
So, Sum of their probabilities will be equal to 1.
[tex]\bold{P(E_1)+P(E_2)=1}\\\Rightarrow 0.034+P(E_2)=1\\\Rightarrow P(E_2)=1-0.034\\\Rightarrow P(E_2)=\bold{0.966}[/tex]

The price-demand equation for gasoline is 0.3d + 4p = 80, where p is the price per gallon in dollars and d is the daily demand measured in millions of gallons. Write the demand d as a function of price What is the demand if the price is $ 8 per gallon?
Answer:
The demand d as a function of price is [tex]d=\frac{800}{3} -\frac{40p}{3}[/tex]
The demand if the price is $ 8 per gallon is 160 millions of gallons.
Step-by-step explanation:
You know that the price-demand equation for gasoline is 0.3d + 4p = 80
To write demand d as a function of price p, you must solve for or isolate demand d, remembering that:
All the terms that are multiplying on one side, go to the other side of the equality by dividing, and those that are dividing go to the other side of the equality by multiplying. The terms that are adding go to the other side of the equality by subtracting and those that are subtracting go to the other side by adding.So:
0.3d + 4p = 80
0.3d = 80 - 4p
[tex]d=\frac{80 - 4p}{0.3}[/tex]
[tex]d=\frac{80}{0.3} -\frac{4p}{0.3}[/tex]
[tex]d=\frac{800}{3} -\frac{40p}{3}[/tex]
The demand d as a function of price is [tex]d=\frac{800}{3} -\frac{40p}{3}[/tex]
To determine how much is the quantity demanded if the price is $ 8 per gallon, you simply plug that value into the previously determined expression and perform the corresponding calculations:
[tex]d=\frac{800}{3} -\frac{40*8}{3}[/tex]
[tex]d=\frac{800}{3} -\frac{320}{3}[/tex]
d= 160
The demand if the price is $ 8 per gallon is 160 millions of gallons.
Consider the Line L(t) = <2+t,5-4t>. Then L intersects:
The x- axis at the point (3.25,0) when t = 5/4
The y- axis at the point (0, 13) when t = -2
The parabola y = x^2 at the points ___ and ___ when t = ____ and ____
Answer:
The parabola [tex]y=x^{2}[/tex] at the points [tex](-2+\sqrt{17},21-4\sqrt{17})[/tex] and [tex](-2-\sqrt{17},21+4\sqrt{17})[/tex] when [tex]t=t_{1}=-4+\sqrt{17}[/tex] and [tex]t=t_{2}=-4-\sqrt{17}[/tex]
Step-by-step explanation:
We have the following line written in parametric form :
[tex]L(t)=(2+t,5-4t)[/tex] with [tex]t[/tex] ∈ IR.
In order to find the intersection between [tex]L(t)[/tex] and the parabola [tex]y=x^{2}[/tex] we know that ''[tex]2+t[/tex]'' is the x-coordinate of the line and ''[tex]5-4t[/tex]'' is the y-coordinate of the line. Now, to solve this problem we need to find the values of ''[tex]t[/tex]'' in which the intersection occurs. We can do this by replacing the components ''[tex]x[/tex]'' and ''[tex]y[/tex]'' of [tex]L(t)[/tex] in the equation of the parabola ⇒
[tex]L(t)=(2+t,5-4t)[/tex] = ( x component , y component ) = ( x , y ) ⇒
In the parabola : [tex]y=x^{2}[/tex] ⇒ [tex]5-4t=(2+t)^{2}[/tex]
Solving the equation we find that :
[tex]t^{2}+8t-1=0[/tex]
Using the quadratic formula with
[tex]a=1[/tex] , [tex]b=8[/tex] and [tex]c=-1[/tex]
We find that the two possible values for t :
[tex]t_{1}=\frac{-b+\sqrt{b^{2}-4ac}}{2a}[/tex] and [tex]t_{2}=\frac{-b-\sqrt{b^{2}-4ac}}{2a}[/tex]
are [tex]t_{1}=-4+\sqrt{17}[/tex] and [tex]t_{2}=-4-\sqrt{17}[/tex]
This values [tex]t_{1}[/tex] and [tex]t_{2}[/tex] are the values of the parameter t where the line intersects the parabola so we can find the points by replacing the values of the parameter in the equation [tex]L(t)[/tex] :
[tex]L(t_{1})=(-2+\sqrt{17},21-4\sqrt{17})[/tex] and
[tex]L(t_{2})=(-2-\sqrt{17},21+4\sqrt{17})[/tex]
The final answer is
The parabola [tex]y=x^{2}[/tex] at the points [tex](-2+\sqrt{17},21-4\sqrt{17})[/tex] and [tex](-2-\sqrt{17},21+4\sqrt{17})[/tex] when [tex]t=t_{1}=-4+\sqrt{17}[/tex] and [tex]t=t_{2}=-4-\sqrt{17}[/tex]
