When jack bought his new truck, there were 96 different ways his truck could be equipped. He had four choices of engines and two choices of transmissions. If only other choice was color, how many colors were available?
To Find all the different ways the truck could be, you would mutiply all the choices together.
There were three different choices.
Multiply the two known ones together than divide the total different ways by that to find the third choice.
4 x 2 = 8
96 / 8 = 12
There are 12 colors available.
Answer:
There are 12 colors available
Step-by-step explanation:
We have product rule which states that if there are [tex]n_{1}[/tex] ways of doing one task, and [tex]n_{2}[/tex] ways of doing another task then there [tex]n_{1}n_{2}[/tex] ways of doing the tasks together.
Let us assume that there are x choices for colors
so we have 4 ways of selecting engines , 2 ways of selecting transmissions and x ways of selecting colors
number of ways of truck could be equipped = [tex]4*2*x[/tex]
= [tex]8x[/tex]
it is given that number of ways truck could be equipped= [tex]96[/tex]
so we have
[tex]8x= 96[/tex]
[tex]x=\frac{96}{8}[/tex] ( divide both side by 8)
[tex]x= 12[/tex]
There are 12 colors available
Using the distributive property, which number sentence represents the total area of the rectangle?
A) 4 x 5 = 20 square units
B) (4 x 3) + (4 x 2) = 20 square units
C) (4 x 3) + (3 x 2) = 18 square units
D) (4 x 3) + (4 x 3) = 24 square units
The correct option that represents the total area of the rectangle using the distributive property is B) (4 x 3) + (4 x 2) = 20 square units.
Explanation:The correct option that represents the total area of the rectangle using the distributive property is B) (4 x 3) + (4 x 2) = 20 square units.
The distributive property states that when you multiply a number by a sum or difference of numbers, you can multiply each number individually and then add or subtract the products.
In this case, the rectangle has a length of 4 units and a width of 3 units.
So, the area of the rectangle can be found by multiplying the length by the width, which is 4 multiplied by 3. Then, you add the product of the length multiplied by the width, which is 4 multiplied by 2. This gives us a total area of 20 square units.
How do you solve by graphing
Answer:
See Explanation Below :)
Step-by-step explanation:
To solve a pair linear equations by graphing, you would first need to find the slope and y-intercept of each of the equation and then graph it in a coordinate plane. Then, you would see where the two lines intersect, and the coressponding coordinates for that point will be your solution.
Example:
y = 2x +2
y = x -1
For the first equation we know the slope (m) is 2 becuase y = mx + b, and m is 2. We know that the y intercept (b) is also 2 becuase y = mx + b, and b is 2.
Similarly, for the second equation the slope (m) is 1 and the y-intercept (b) is -1.
When you use this data and plot the two lines, we can see that they intersect on the 3rd quadrant at (-3,-4) which will be your solution. See the attached graph for this example.
Simplify -20b^8 + 2b^8
Answer:
Step-by-step explanation:
Answer:
-18b^8.
Step-by-step explanation:
To simplify an expression, we combine the elements that are similar (look the same).
So, it we have -20b^8 + 2b^8, we see that there are 2 terms with b^8. We need to simplify them.
So, we have -20b^8 + 2b^8, that addition leaves -18b^8.
-18b^8 cannot be simplified more.

Two coins are flipped. What is the probability that both of the coins land on heads up
Answer:
0.25, 25%, or 1/4
Step-by-step explanation:
There are two possibilities for each coin: heads or tails. So the chance of getting heads for the first flip is 50%, or 1/2. To find the probability for both, you multiply 1/2*1/2 and get 1/4.
The probability that both of the coins land on heads up when two coins are flipped is 1/4. This can be obtained by obtaining the possible outcomes and using formula for probability.
What is the formula of Probability?The formula of Probability is,
P= number of favorable outcomes/ total number of outcomes
Calculate the probability for the question:When two coins are flipped the possible outcomes are,(H,H), (H,T), (T,H), (T,T), that is, the total number of outcome is 4.
The outcome where both of the coins land on heads up is (H,H),that is, the number of favorable outcome is 1.
Thus the probabilty is, P(both coins heads up)=1/4Hence the probability that both of the coins land on heads up when two coins are flipped is 1/4.

What is the smallest solution to this equation?
Answer:
x = - 6
Step-by-step explanation:
Given
[tex]\frac{2}{3}[/tex] x² = 24 ( multiply both sides by 3 )
2x² = 72 ( divide both sides by 2 )
x² = 36 ( take the square root of both sides )
x = ± [tex]\sqrt{36}[/tex] ← note plus or minus
x = ± 6
solutions are x = - 6, x = + 6
The smallest solution is x = - 6

Step-by-step explanation: Since we know that segment AB and BC are the same measure indicated by the black lines running perpendicular to the lines in triangle themselves, we know that angle A and angle C are the same measure. This means we know this equation... Solve this to complete step 1...
69°=(9y-3)°
If you solve for y, you should get 8. This means that y=8. In knowing that a triangle's interior angles add up to 180°, we know that Angle B must be... Solve this equation for step 2...
∠B=180°-(∠A+∠C)
If you solve to find angle B, you should get that ∠B=42°. Knowing this, we can set up another equation similar to that in step 1 (when we found y knowing the angle) to find x... Solve this equation for your third and final step...
42°=(5x+2)°
If done step 1 through 3 correctly, you should get x to be equal to... and the final answer... x=8
You can rent time on computers at the local copy center for a $6 setup charge and an additional $5.50 for every 10 minutes. How much time can be rented for $21?
21$ is the start.
You need to take 6$ off because of the setup charge.
21-6= 15$ left
Every 10 minutes costs $5.50 so you need to divide 5.50 from 15 and multiply that answer by 10. 20 minutes can be rented. with 4$ left
Darren is painting a wooden block as part of his art project. The block is a rectangular prism that is 12 cm long by 9 cm wide by 5 cm high. Describe the rectangles that make up the net for a prism
Answer:
The answer in the procedure
Step-by-step explanation:
we know that
The rectangles that make up the net for a prism are six rectangles
two rectangles are L by W ----> 12 cm by 9 cm
two rectangles are L by H ----> 12 cm by 5 cm
two rectangles are W by H ---> 9 cm by 5 cm
Final answer:
The rectangular prism net Darren is painting consists of two 12x5 cm rectangles for the top and bottom, two 9x5 cm rectangles for the front and back, and two 12x9 cm rectangles for the sides.
Explanation:
Darren is working on an art project involving painting a wooden block that is in the shape of a rectangular prism. To understand the net for this prism, we need to describe the rectangles that would make it up when the prism is unfolded into a flat shape.
The net of a rectangular prism is made up of six rectangles, each corresponding to a face of the prism. For Darren's block, which has dimensions of 12 cm in length, 9 cm in width, and 5 cm in height, we can determine the rectangles as follows:
When painting, Darren would treat each of these rectangles as separate sections to ensure complete coverage.

1) A new truck that sells for $42,000 depreciates 11% each year. write a function that models the value of the truck. Find the value of the truck after 8 years. Round to the nearest dollar.
2) Earl mows lawns one weekend. He earns $15 for each lawn that he mows. He spends $50 on gas and other supplies. What function equation represents Earl's profit from mowing x lawns?
A)f(x)=50x-15
B)f(x)=50x+15
C)f(x)=15x-50
D)f(x)=15+50
3) find the common geometric series.
-2,-4,-8,-16.....
Answer:
[tex]\boxed{1) V = 40 000(0.89)^{n}, \text{\$15 746; }\text{2) C) f(x) = 15x - 50 ; 3) }a_{n} = -2^{n}}[/tex]
Step-by-step explanation:
1) Depreciation
The formula for the value V of an asset after depreciation by an annual percentage rate is
V = P(1 - r)ⁿ
where
P = present value
r = annual percentage rate
n = number of years
Data:
V = 40 000
r = 11 % = 0.11
n = 8 yr
Calculations:
(a) Function model
V= 40 000(1 - 0.11)ⁿ = 40 000(0.89)ⁿ
The function model is [tex]\boxed{ V= 40 000(0.89)^{n} }[/tex]
(b) Future value
V = 40 000(0.89)ⁿ = 40 000 × 0.393 659 = $15 746
In eight years, the truck will be worth [tex]\boxed{ \text{\$15 476}}.[/tex]
2) Profit function
Income from 1 lawn = $15
Income from x lawns = 15x
Less gas and supplies = -50
Net income = 15x – 50
The function is [tex]\boxed{f(x) = 15x - 50}[/tex].
3) Geometric series
(a) Calculate the common ratio
a₁ = -2
a₂ = -4
a₃ = -8
a₄ = =16
The ratios of consecutive pairs are
a₄/a₃ = -16/(-8) = 2
a₃/a₂ = -8/(-4) = 2
a₂/a₁ = -4/(-2) = 2
All adjacent pairs have the same common ratio r = 2.
(b) Write the formula for the series
The formula for the nth term of a geometric series is
aₙ = a₁rⁿ⁻¹
If a₁ = -2, the formula for the series is
aₙ = -2(2)ⁿ⁻¹ = -2ⁿ
The formula for the series is [tex]\boxed{a_{n} = -2^{n}}[/tex].
Two cyclists left simultaneously from cities A and B heading towards each other at constant rates and met in 5 hours. The rate of the cyclist from A was 3 mph less than the rate of the other cyclist. If the cyclist from B had started moving 30 minutes later than the other cyclist, then the two cyclists would have met 31.8 miles away from A. What is the distance between A and B, in miles?
Answer:
73.92 miles
Step-by-step explanation:
Formula for calculating distance = speed × time
Rate/speed of cyclist from city A = ( x - 3 ) mph , Time Taken = 5 Hours
Rate/speed of cyclist from city B = x mph
If Cyclist from B had started moving 30 minutes later
Time Taken by cyclist from B = 4.5 Hours
If B had started 30 minutes later, then the two cyclist would have met 31.8 miles from A.
distance covered by cyclist from A = 31.8
Solution:
For city A:
distance = speed × time
31.8 = ( x - 3 ) × 5 ⇒ [tex]\frac{31.8}{5}[/tex] = x - 3
6.36 = x - 3 ⇒ x = 6.36 + 3 ⇒ x = 9.36 mph
For city B:
distance = speed × time
= 9.36 × 4.5
= 42.12 miles
Distance between A and B = 31.8 + 42.12
= 73.92 miles
Write the equation of a line in slope intercept form that has a slope of 1/5 and contains (-10,6)
Answer:
y = [tex]\frac{1}{5}[/tex] x + 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
here m = [tex]\frac{1}{5}[/tex], hence
y = [tex]\frac{1}{5}[/tex] x + c ← is the partial equation
To find c substitute (- 10, 6) into the partial equation
6 = - 2 + c ⇒ c = 6 + 2 = 8
y = [tex]\frac{1}{5}[/tex] x + 8
The function f(x)=x^2+4.2x+3.6 has an axis of symmetof x=-2-. What is the minimum value of the function
ANSWER
The minimum value is -0.8
EXPLANATION
The given
[tex]f(x)=x^2+4.2x+3.6[/tex]

Tom is clearing brush from a large piece of land. The table shows how many acres he cleared over time
Tom takes 1 day to clear 1 acre.
To find out how many days it takes Tom to clear 1 acre, we can calculate the rate at which he clears brush in acres per day.
Let's use the given information:
[tex]\frac{2}{3}[/tex] acre cleared in 2 days,
[tex]1\frac{2}{3}[/tex] acres cleared in 5 days,
[tex]2 \frac{1}{3}[/tex] acres cleared in 7 days.
First, let's find the rate in acres per day for each interval:
For the first interval:
[tex]\frac{\frac{2}{3} }{2} = \frac{1}{3}[/tex] acre per day.
For the second interval:
[tex]\frac{1\frac{2}{3} }{5} = \frac{5}{3} \times \frac{1}{5} = \frac{1}{3}[/tex] acre per day.
For the third interval:
[tex]\frac{2\frac{1}{3} }{7} = \frac{7}{3} \times \frac{1}{7} = \frac{1}{3}[/tex] acre per day.
It appears that the rate at which Tom is clearing brush is consistent at
[tex]\frac{1}{3}[/tex] acre per day.
Therefore, Tom takes 1 day to clear 1 acre.

whats the y-intercept of 5x-3y=4
Answer:
y = - [tex]\frac{4}{3}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange 5x - 3y = 4 into this form
Subtract 5x from both sides
- 3y = - 5x + 4 ( divide all terms by - 3 )
y = [tex]\frac{5}{3}[/tex] x - [tex]\frac{4}{3}[/tex] ← in slope- intercept form
with y- intercept c = - [tex]\frac{4}{3}[/tex]
Method 1: Plunging in 0 for x in the equation and solve for y
5(0) - 3y = 4
0 - 3y = 4
-3y= 4
y = [tex]\frac{-4}{3}[/tex] <<< y - intercept
Method 2: Converting the equation to slope-intercept form ( y = mx + b) and see what b is (that is the y-intercept). Do do this isolate y
-3y = 4 - 5x
y = [tex]\frac{-4}{3} +\frac{5}{3} x[/tex]
[tex]y = \frac{5}{3} x- \frac{4}{3}[/tex]
b = [tex]\frac{-4}{3}[/tex] <<< y - intercept
Y- intercept : (0, [tex]\frac{-4}{3}[/tex])
