driven x miles.
a. What is the truck rental cost when you drive 145 miles?
b. How many miles did you drive when your cost is $51.56?
Answer:
a. $89.30
b. 34 miles
Step-by-step explanation:
a. c(x)= 0.34(145)+40
=$89.3
b. 51.56=0.34x+40
-40 -40
11.56=0.34x
0.34. 0.34

Seven less than sixteen times a number is equal to the same number reduced by 5. What is the number?
Answer:
x = 2/15
Step-by-step explanation:
first, create a formula or expression
16x - 7 = x - 5
move x, subtract it
15x - 7 = -5
add 7
15x = 2
divide by 15
x = 2/15

A particle moves along a circular path with radius 3 centimeters. The particle has an angular velocity of 3π/4 radians per second. What is the length of the arc, in centimeters, generated after 5 seconds? Round your answer to the nearest tenth.
After 5 s, the particle traverses a path subtended by an angle of
(3π/4 rad/s) (5 s) = 15π/4 rad
Now, 15π/4 rad = 15/8 * 2π rad, so the arc has a length equal to 15/8 of the circumference of the path:
15/8 * 2π * (3 cm) = 45π/4 cm ≈ 35.3 cm

Choose the correct label for the point on the boxplot represented by the question mark
O 01
O Q3
OM
O min
Омах
QR
O Range
None of the above
Answer:
None of the above.
Step-by-step explanation:
The box plot given has an asterisk which represents an outlier in the data set plotted. This outlier is an extreme data set value which is obviously the maximum value in the data set.
The question mark can be regarded as the highest observation that doesn't take the outlier observation into consideration.
Therefore, none of the options given is the correct label for the point on the box plot represented by the question mark.

3. The following are the values of a, b, and c that Edna, Luisa,
Jane
and Christy got when they expressed 5-3x = 2x² in standard form
Edna :a=-2, b = -3,c=5.
Jane: a=2, b= -3,C=-5
Luisa : a = -2,b=3,6=-5 Christy: a=-2, b = -3,6=-5
who do you think got the correct values of ab
and c in the given equation?
a. Edna
b. Luisa
Jane
d. Christy
Answer:
a = 2
b = 3
c = -5
Step-by-step explanation:
We are given Algebraic expression:
5-3x = 2x²
We rewrite it in standard form
2x² + 3x - 5
Algebraic form :
ax² + bx + c
Hence, the values of a, b, c is given below:
a = 2
b = 3
c = -5
if the ratio of shirts to jeans 5:2 and number of shirts are 15 what is the the number of jeans
Answer:
We are given that the ratio of shirts to jeans is 5 : 2
This means that for every 5 shirts, we have 2 jeans
it also means that the number of shirts / number of jeans = 5 / 2
Since we are given the number of shirts,
we can easily find the number of jeans
(15) / (number of jeans) = 5 / 2
Number of Jeans = (15) * (2 / 5)
Number of Jeans = 6
Answer:
6 jeansStep-by-step explanation:
ratio of shirt to jeans = 5:2
shirt = 15
jeans = ??
ratio and proportion:
5 shirt = 15 shirts
2 jeans x jeans
cross multiply:
15 (2) = 5 (x)
x = 30 / 5
x = 6 jeans
The midpoint of JKis M (6, 3). One endpoint is J (14, 9). Find the coordinates of endpoint K.
The endpoint K (-2, -3)
Answer:
The coordinates of endpoint K are (-2,-3)
Step-by-step explanation:
Midpoint
Given two points J(jx, jy) and K(kx, ky), the coordinates of the midpoint M(mx,my) are given by:
[tex]\displaystyle m_x=\frac{j_x+k_x}{2}[/tex]
[tex]\displaystyle m_y=\frac{j_y+k_y}{2}[/tex]
We are given the coordinates of M and need to find the coordinates of K. From the equations above, solve for kx and ky:
[tex]k_x=2m_x-j_x[/tex]
[tex]k_y=2m_y-j_y[/tex]
The points are M(6,3) and J(14,9), thus:
[tex]k_x=2\cdot 6-14=-2[/tex]
[tex]k_y=2\cdot 3-9=-3[/tex]
The coordinates of endpoint K are (-2,-3)

– 2(3x – 5) – 12x - 2
Answer:
-18x+8
Step-by-step explanation:
First you have to distribute the -2 to the 3x and the -5 in the parenthesis giving you -6x+10-12x-2.
Next you combine like terms which gives you -18x+8

Jeff and his roommate are in the cake baking business. When they receive an order over the internet, Jeff prepares a bowl and mixes cake batter according to the order (takes 6 minutes). He then pours the batter into a baking pan that holds 1 cake (2 minutes). His roommate then puts the cake pan in the oven and sets a timer (1 minute). Cakes bake in the oven for 9 minutes and then are cooled outside the oven on a rack for 5 minutes. Finally the roommate takes 2 minutes to box the cake and then collects payment from the arriving customer (1 minute).
Expect that each order is composed of a two tier cake (2 cakes). Although the mixing bowl can hold batter for two cakes at one time, assume the oven can only hold one cake pan at a time. As mentioned above, pouring batter into each pan takes 2 minutes, and both cakes must be cooled before boxing the cake for the customer.
A. Determine theoretical flow time from the order thru payment. Assume no waiting over the entire process.
B. Buy a second oven that can bake one cake pan (plus existing oven cooking 1 cake pan).
C. Replace oven with one that can hold two cake pans at the same time (still 9 min bake).
D. Replace oven with a faster convection oven that can bake one cake pan in 6 minutes (instead of 9).
