both drive at a constant speed for 45 minutes, but your speed is 40 miles per hour and your friend’s speed is 35 miles per hour. What is the total distance between your town and your friend’s town?
Answer:
Your distance: 1800 miles Your friend's distance: 1575 miles
Total: 3375 miles
Step-by-step explanation:
Distance= S * T
The s stands for speed and t for time.
Your distance:
D= 45 * 40
D= 1800 miles
Your friend's distance:
D= 35 * 45
D= 1575 Miles
Total distance: 1800 + 1575 = 3375 MILES

A flagpole has a height of 25 meters. There are approximately 3.3 feet in 1 meter.
How tall is the flagpole, in feet, rounded to the nearest tenth?
Answer:
Step-by-step explanation:53
The height of the flagpole is 82.5 feet.
What is unit of Measurement?A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity.
Given that a flagpole has a height of 25 meters.
We know that there is 3.3 feet in 1 meter.
1 meter=3.3 feet.
Now we have to find the height in feet.
So we have to multiply twenty five with three point three
25×3.3=82.5 feet
25 meters=82.5 feet.
Hence, a flagpole has a height of 82.5 feet.

=============================================
Explanation:
We can set up the following proportion
a/b = c/d
where the numerators 'a' and 'c' represent the scaled down dimensions, and b and d represent the actual real life dimensions.
For this particular problem, we have to keep in mind that 'a' and 'c' are in cm; while b and d are in inches.
So we could have
a = 16.8 cmb = 84 inchesc = 15 cmd = x inches, where x is unknown for nowSince d is in inches, this makes x be in inches as well.
------------------
Let's solve for x
a/b = c/d
16.8/84 = 15/x
16.8x = 84*15 ..... cross multiply
16.8x = 1260
x = 1260/16.8
x = 75
The suspect is 75 inches tall. This converts to 75/12 = 6.25 feet or 6 feet 3 inches (since 0.25 ft = 0.25*12 = 3 ft)
Find k so that the distance from (–3, –1) to (k, 5) is 10 units.
Answer:
k = - 11, 5
Step-by-step explanation:
By distance formula:
[tex] \sqrt{ \{ {k - ( - 3) \}}^{2} + \{5 - ( - 1) \}^{2} } = 10 \\ \\ \sqrt{ {(k + 3)}^{2} + {(5 + 1)}^{2} } = 10 \\ \\ \sqrt{ {(k + 3)}^{2} + {(6)}^{2} } = 10 \\ \\ \sqrt{ {(k + 3)}^{2} + 36 } = 10 \\ \\ (k + 3)^{2} + 36 = {10}^{2} \\ ..(squaring \: both \: sides) \\ {k}^{2} + 6k + 9 + 36 = 100 \\ {k}^{2} + 6k + 45 - 100 = 0 \\ {k}^{2} + 6k - 55 = 0 \\ {k}^{2} + 11k - 5k - 55 = 0 \\ k(k + 11) - 5(k + 11) = 0 \\ (k + 11)(k - 5) = 0 \\ k + 11 = 0 \: or \: k - 5 = 0 \\ k = - 11 \: or \: k = 5 \\ \\ \huge \red { \boxed{k = \{ - 11, \: 5\}}}[/tex]
There are two solutions for [tex]k[/tex]: 5 and -11.
In this case, we must use the Length Equation for Line Segment to solve for [tex]k[/tex], whose formula is described below:
[tex]l = \sqrt{(x_{B}-x_{A})^{2}+ (y_{B}-y_{A})^{2}}[/tex] (1)
Where:
[tex](x_{A}, y_{A})[/tex] - Coordinates of the initial endpoint.
[tex](x_{B}, y_{B})[/tex] - Coordinates of the final endpoint.
[tex]l[/tex] - Length of the line segment.
If we know that [tex](x_{A}, y_{A}) = (-3, -1)[/tex], [tex](x_{B}, y_{B}) = (k, 5)[/tex] and [tex]l = 10[/tex], then the equation is expanded into this form:
[tex](k+3)^{2}+[5-(-1)]^{2} = 100[/tex]
[tex]k^{2}+6\cdot k + 9 + 36 = 100[/tex]
[tex]k^{2} + 6\cdot k -55 = 0[/tex]
The roots of this Second Order Polynomial are determined by Quadratic Formula:
[tex]k = 5[/tex] or [tex]k = -11[/tex].
There are two solutions for [tex]k[/tex]: 5 and -11.

Answer:
Factors: (x²y+6)(y²-11)
Step-by-step explanation:
Here's the original equation.
x²y³ - 11x²y + 6y² - 66
Let's separate it into two groups to make it easier.
(x²y³ - 11x²y) + (6y² - 66)
Let's take a look at (x²y³ - 11x²y) first. Do we notice anything that can be removed from the parentheses?
Yes, x²y can be taken from both polynomials to simplify the contents of the parentheses.
Both polynomials have x² and both have at least one y. Combine that to get x²y. That means that within the parentheses y² and - 11 will be left.
So (x²y³ - 11x²y) becomes x²y (y²-11)
This works because if we multiply x²y * (y² - 11) we get (x²y³ - 11x²)
Let's apply this same idea to (6y² - 66).
6 is the only thing in common between the two polynomials.
If we follow the same steps we get 6 (y²-11).
Notice how when we simplified both groups they each had something on the outside and (y² - 11) in the parentheses?
So lets combine the things that were on the outside of both (y² - 11).
What was on the outside of each? x²y was on the outside for the first one, and 6 for the outside of the second one.
This means that if we combine everything and simplify, the factors we have are (x²y+6)(y²-11).
If you want to confirm, work your way backwards using the distributive property. You'll find that when you multiply (x²y+6) * (y² -11) you'll get = x²y³ - 11x²y + 6y² - 66. That was the original equation, so we know that these are the factors.
Hope that helps!

A total of 500 married working couples were polled about their annual salaries, with the following information resulting: Husband Wife Less than More than $25,000 $25,000 Less than $25,000 212 198 More than $25,000 36 54 For instance, in 36 of the couples, the wife earned more and the husband earned less than $25,000. If one of the couples is randomly chosen, what is (a) the probability that the husband earns less than $25,000
Answer:
36/500
Step-by-step explanation:
The probability that the husband earns less than $25,000 is 0.496.
Given that,
A total of 500 married working couples were polled about their annual salaries, with the following information resulting:
Husband
Wife Less than $25,000 More than $25,000
Less than $25,000 212 198
More than $25,000 36 54
Thus, for instance, in 36 of the couples, the wife earned more and the husband earned less than $25,000. If one of the couples is randomly chosen.
We have to determine,
What is the probability that the husband earns less than $25,000?
According to the question,
The probability that the husband earned less than $25,000 is,
Total number of couples = 500
The count of husbands earning less than $25,000 is 212 and 36.
[tex]\rm Probability = \dfrac{Total \ number \ of \ couples}{Husband \ earn \ less \ than \ 25000}\\\\ Probability= \dfrac{212+36}{212+36+198+54}\\\\Probability = \dfrac{246}{500}\\\\Probability = 0.496[/tex]
Hence, The probability that the husband earns less than $25,000 is 0.496.

If the radius of circle A is 2 inches, the radius of circle B is 3 1/4 and the radius of circle C is 1 inch, what is the perimeter of ABC?
Answer:
39.26 in
Step-by-step explanation:
This problem, bothers on the mensuration of flat shapes.
we know that the perimeter of a circle is the same as the cirmcumference
we also know that the circumference is given as
C= 2πr
For circle A
C=2*3.124*2
C= 12.56 in
For circle B
C=2*3.124* 3 1/4
C= 2*3.142*13/4
C= 2*3.142*3.25
C= 20.42 in
For circle C
C=2*3.124*1
C= 6.284 in
Now the perimeter of all the circles ABC is
=12.56 +20.42 + 6.284
=39.26 in
