Answer: 290 miles
Step-by-step explanation:
Distance = speed × time
(65 × 1.5) + ( 55 × 3.5)
97.5 + 192.5
The first step when adding or subtracting rational expression with unlike denominator is to
To add or subtract rational expressions with unlike denominators, first find the LCM of the denominator. The LCM of the denominators of fraction or rational expressions is also called least common denominator, or LCD. Write each expression using the LCD.
Adding or subtracting rational expressions is remarkably similar to adding and subtracting fractions, since a rational expression is a fraction.
The operations are the same.
When adding or subtracting fractions with unlike denominators, we multiply the denominator of one fraction times the denominator of the other fraction, and then alter the numerators.
The process with rational expressions is the same.
So the first step is to make sure both rational expressions have the same denominator.

Adrian is planning to drive from City X to City Y. The scale drawing below shows the distance between the two cities with a scale of ¼ inch = 18 miles.
City X to City Y is 3 1/2 in.
If Adrian drives at an average speed of 30 miles per hour during the entire trip, how much time, in hours and minutes, will it take him to drive from City X to City Y?
Answer:
takes him 8.4 hrs
Step-by-step explanation:
if 1/4=18inch then 3 1/2=7/2 so 7/2 divide by 1/4=14 then 18 x 14=252
so distance is 252 miles
speed is 30mph so 252/30=8.4h
the answer might need the 0.4 in hrs too

Darnell collected data from two different sales teams in his department, each with four employees the results of the study, based on each workers age and sales, are listed in the tables below. Which of the following is a true statement
The correct statement states that the sales range for team 2 is greater than the sales range for team 1.
What is the range?The range is defined as the difference between the maximum value to the minimum value.
Team 1
Worker's Age Sales
25 30,000
27 29,000
28 32,000
33 35,500
Team 2
Worker's Age Sales
25 35,000
28 37,000
29 38,000
31 65,000
Range Team 1 = 38000 - 30000 = 8000
Range Team 2 = 65000 - 29000 = 36000
Thus, The sales range for team 2 is greater than the sales range for team 1.

Write the expression in exponential form.
Answer:
In exponential form given function is equal to [tex]N = b^{r}[/tex]
Step-by-step explanation:
We are given with function,
[tex]log_{b} ^[/tex] [tex]^{N} = r[/tex]
We have to express it in exponential form.
Consider,
[tex]log_{b}^[/tex] [tex]^ {N} = r[/tex]
exponential both side to the power of b as base of given log function is b.
we get
[tex]b ^{logb}[/tex] [tex]^ {N} = b^{r}[/tex]
[tex]N = b^{r}[/tex]
Therefore In exponential form given function is equal to [tex]N = b^ {r}[/tex]

Find the volume of the sphere shown. Give each answer round to the nearest cubic unit. 15 CM
Answer:
a
Step-by-step explanation:
the volume (V) of a sphere is calculated as
V = [tex]\frac{4}{3}[/tex]πr³ ( r is the radius )
here the diameter = 15, then r = 15 ÷ 2 = 7.5 , then
V = [tex]\frac{4}{3}[/tex]π × 7.5³
= [tex]\frac{4}{3}[/tex]π × 421.875
= [tex]\frac{4\pi (421.875)}{3}[/tex]
≈ 1767 cm³ ( to the nearest cubic cm )

1. Find the volume of the solid that results when the region enclosed by the given curves = ^(−2), = 0, = 0, and = 1 is revolved about the x-axis.
2. Find the volume of the solid that results when the region enclosed by the given curves = ^(−2), = 0, = 0, and = 1 is revolved about the y-axis.
The volume of the solid that results when the region enclosed by the given curves y = e⁻²ˣ, y = 0, x = 0, and x = 1 is revolved around the x-axis and the y-axis is 0.77 and 0.7135.
What is the revolution of the curve?Revolving the region bordered by y = f(x) and the x-axis on the interval [a, b] around the x-axis generates the volume (V) of a solid.
The volume is given as
[tex]\rm Volume = \int _a^b \pi y^2 \ dx[/tex]
The volume of the solid that results when the region enclosed by the given curves y = e⁻²ˣ, y = 0, x = 0, and x = 1 is revolved around the x-axis.
[tex]\rm Volume = \int _0^1 \pi (e^{-2x})^2 \ dx\\\\\\Volume = \int _0^1 \pi (e^{-4x}) dx\\\\\\Volume = \pi [\dfrac{e^{-4x}}{-4}]_0^1\\\\\\Volume = - \dfrac{\pi}{4} [e^{-4} - e^0]\\\\\\Volume = -\dfrac{\pi}{4} [-0.98168]\\\\\\Volume = 0.77[/tex]
The volume of the solid that results when the region enclosed by the given curves y = e⁻²ˣ, y = 0, x = 0, and x = 1 is revolved around the y-axis.
[tex]\rm Volume = \pi \left [\int_{0}^{0.135} dy + \int_{0.135}^{1}\left ( \dfrac{\ln x}{-2} \right )^{2}dy \right ]\\\\Volume =0.71375[/tex]
