Answer:
1 1/4 milesStep-by-step explanation:
Amount of miles ran as part of an exercise routine = 7 1/2 miles = 15/2 miles
If you run 1/2 of that distance on a hill, the distance ran on the hill will be;
= 1/2 of 15/2
= 1/2 * 15/2
= 15/4 miles
If You run down a slope for the last 1/3 of the hill, the number of miles that you run down the hill will be;
1/3 of 15/4
= 1/3 * 15/4
= 15/12
= (3*5)/(3*4)
= 5/4
Write 5/4 as a mixed fraction
5/4 = 1 1/4 miles
Therefore you ran 1 1/4 miles down the slope

Answer:
x=60
Step-by-step explanation:
Answer: The equation 60 + x= 3x -70 could be set up to solve for x.
Step-by-step explanation:
The two remote interior angles sums will equal to the exterior angle .
Meaning that angle 60 plus angle x has to equal to angle 3x -70.
60 + x= 3x -70 Now solve for x by adding 70 to both sides
+70 +70
130 + x = 3x Now subtract x from both sides
-x -x
130 = 2x Divide both sides by
x = 65

Diane flipped a coin 600 times and it landed heads up 240 times. What is the relative frequency of the coin landing heads up based on the results of this experiment?
4%
6%
40%
60%
Step-by-step explanation:
The relative frequency of the coin landing heads up is 0.4 or 40%.
Step-by-step explanation:
We are given that,
Total number of times coin is tossed = 600
Number of times heads comes = 240
Since, 'relative frequency' is the fraction of number of times an event occurs and the total number of events.
Thus, the relative frequency that heads comes = \frac{240}{600}
600
240
i.e. Relative frequency that heads comes = 0.4 or 40%
Thus, the relative frequency of the coin landing heads up is 0.4 or 40%.
Answer: 40%

the difference between two numbers is 48. the ratio of the two nukbers is 7:3. what are tge two numbers
The difference between the two numbers is 48. The ratio of the two numbers is 7 : 3. Hence, 84 and 36 are the two numbers.
Given :-
The difference between the two numbers is 48.
The ratio of the two numbers is 7 : 3.
To Find :-
The Two Numbers
Solution :-
Let the first number be 7x
And the second number be 3x
According to the Question,
⇒ 7x - 48= 3x
⇒ 7x-3x = 48
⇒ 4x = 48
⇒ x = 48/4
⇒ x = 12
1st number is= 7x = 84
2nd number= 3x = 36
Hence, 84 and 36 are the two number

The y-intercept is the y value when x = 0. Another way to reword that is when the graph crosses the y-axis. The x-intercept is the x value when y = 0. Another way to reword that is when the graph crosses the x-axis.Step-by-step explanation:
x-int
According to the graph, it crosses the x-axis at 5. Therefore, our x-int is (5, 0)
y-int
According to the graph, it crosses the y-axis at 4. Therefore, our y-int is (0, 4)
A line's y-intercept is 9, and its slope is 10. What is its equation in slope-intercept form?
Answer:
y=10x+9
Step-by-step explanation:
Slope intercept form is y=mx+b
m represents slope so 10 replaces the m
b represents the y-intercept (where the line crosses the y-axis) so 9 replaces the b
Is 0.000027 greater than 270?
Answer:
no because it is lower than 1 and 270 is higher

Mrs. Dobbs rides a taxi that charges a flat rate of $6.75 plus $3.20 per mile. The taxi charges Lupita $40.03 in total for her trip.
Subtract the flat rate from the total, then divide by price per mile for total miles:
40.03 - 6.75 = 33.28
33.28/3.20 = 10.4 miles.
Lupita drove 10.4 Miles for her trip.
Explanation:
40.03 - 6.75 = 33.28 dollars left
33.28 ÷ 3.20 = 10.4 Miles
Find the hypothesis for side a 16 side b 20
I think you mean to say "hypotenuse". If so, then use the pythagorean theorem to get the following
a^2 + b^2 = c^2
16^2 + 20^2 = c^2
256 + 400 = c^2
656 = c^2
c^2 = 656
c = sqrt(656)
c = sqrt(16*41)
c = sqrt(16)*sqrt(41)
c = 4*sqrt(41)
The hypotenuse is exactly 4*sqrt(41) units long

Find out how long it takes a $ investment to double if it is invested at compounded . Round to the nearest tenth of a year. Use the formula . A. years B. years C. years D. years
Answer:
(A) 8.8 years
Step-by-step explanation:
Given that the principal amount = $ 3100
Rate of compound interest = 8% compounded semiannually.
The given formula is
[tex]A=P\left(1+\frac{r}{n}\right)^{nt}[/tex]
Where A is the final amount, P is the principal amount, r is the rate of compound interest, t is the time and n is the number of times per year the interest is compounded.
From the given condition,
P=$3100
r= 8%=0.08 compounded semiannually
n=2
A=2 x 3100=$ 6200.
Put all these in the given formula to get the required time, we have
[tex]6200=3100\left(1+\frac{0.08}{2}\right)^{2t}[/tex]
[tex]\Rightarrow \left(1+0.04\right)^{2t}=6200/3100[/tex]
[tex]\Rightarrow 1.04^{2t}=2\\\\\Rightarrow 2t\log_{10}(1.04)=\log_{10}(2)\\ \\\Rightarrow 2t =\frac{\log_{10}(2)}{\log_{10}(1.04)}\\\\\Rightarrow 2t =17.673\\\\\Rightarrow t = 17.673/2=8.8365\\[/tex]
On rounding to the nearest tenth of a year, t=8.8 years.
So, the invested amount will be double in 8.8 years.
Hence, option (A) is correct.

If she earns that much for 18 h, divide the amount she makes in 18 h by 18 parts because 18h/18 = 1 h. If done properly, you will get $7.36.
In which figure is point G a centroid?
a
b
c
d
Answer:
Step-by-step explanation:
You didn't provide us with correct choice
The centroid of a triangle is the point of intersection of its medians.
The lines that pass through the centroid of a triangle divides the side lengths of the triangle into equal halves.
The figure whose centroid is point G is triangle LMN.
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Now, From the attached image, we have the following highlights
There is no evidence that the lines that pass through point G divides the three sides of triangle ABC into equal halves
The lines that pass through point G divides the three sides of triangle LMN into equal halves
The above highlights mean that:
Point G is the centroid of triangle LMN.
Hence, the figure whose centroid is point G is triangle LMN.
