Answer:
20
Step-by-step explanation:
Your equation is correct. To solve it subtract 1.5r from both sides and divide by the resulting coefficient of r.
15 = 0.75r
15/0.75 = r = 20

Directed line segment porque is shown on the coordinate plane. What are the coordinates of the point 1/3 of the way from point P(4,4) to point Q(-2,1)?
Answer: (2,3).
Step-by-step explanation:
We need to find the coordinates of the point 1/3 of the way from point P(4,4) to point Q(-2,1).
Let the point be A.
[tex]PA:PQ=1:3[/tex]
[tex]PA:AQ=PA:(PQ-PA)=1:(3-1)=1:2[/tex]
It means the point A divide the segment PQ in 1:2.
Section formula: If a point divide a segment is m:n.
[tex]\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)[/tex]
[tex]A=\left(\dfrac{1(-2)+2(4)}{1+2},\dfrac{1(1)+2(4)}{1+2}\right)[/tex]
[tex]A=\left(\dfrac{-2+8}{3},\dfrac{1+8}{3}\right)[/tex]
[tex]A=\left(\dfrac{6}{3},\dfrac{9}{3}\right)[/tex]
[tex]A=\left(2,3\right)[/tex]
Therefore, the required coordinates are (2,3).

4) How many km in
58,795cm?
Please help thanks!!
Step-by-step explanation:
1 km is equal to 100,000 cm.
58,795 is close to 50,000, which is half of 100,000. So our estimate would be 1/2 km to 50,000 cm.
Convert 58,795 to a decimal.
0.58795
The decimal cannot be simplified so there is
0.58795 km in 58,795 cm

Solve the compound inequality. −5x≤−10 or 7x−21≥14
-5x ≤ -10
Divide both sides by -5
x ≥ 2
7x - 21 ≥ 14
Add 21 to both sides
7x ≥ 35
Divide both sides by 7

Mr. Green wants to know how far he can run. He knows he can run 103,000 mm. How many miles can he run? Show all work if you want to receive credit.
I know the answer is 0.064 miles but I need the work!! help please
Answer:
1 Mile = 1609000 mm.
1.03 × 10^5 × 6.21371192237337 = 0.064 mile
103000 /1609344= 103000 mm.
Step-by-step explanation:
The beginning process is just to find the amount that mm = miles. After that you will move the decimal to then get 0.064 of a mile.
103,000 mm is 0.064 miles
So he can run 0.064 miles.
Given,
He can run = 103,000 mm
We need to find how many miles he can run.
How many mm in a mile?1 mile = 1609344 mm
Find how many miles is 103,000 mm.
We have,
1 mile = 1609344 mm
Multiplying both sides by 103,000
103,000 x 1 mile = 103,000 mm x 1609344
Divide both sides by 1609344
( 103,000 x 1 mile ) / 1609344 = (103,000 mm x 1609344) / 1609344
0.064 miles = 103,000 mm
This means 103,000 mm is 0.064 miles.
Thus 103,000 mm is 0.064 miles

The table shows the maximum and minimum depths of two submarines. Find the range of depths for each submarine. Then determine which submarine has the greater range of depths.
Submarine A Submarine B
Minimum Depth −146 ft −194 ft
Maximum Depth −532 ft −621 ft
Answer:
Range A = 386ft
Range B = 427ft
B has the larger range.
Explanation:
To find the range, find the difference between the minimum and maximum depths for each submarine. Remember that your answer will be positive.
Sub A:
-146ft - (-532ft) = 386 ft
Sub B:
-194ft - (-621ft) = 427 ft
Submarine B has a larger range.
Solve the literal equation cy−7=5d+3y for y.
y=
Answer: y = 5d + 7 / c - 3
Step-by-step explanation:
Step 1: Add -3y to both sides
cy - 7 + -3y = 5d + 3y + -3y
= cy - 3y - 7 = 5d
Step 2: Now, add 7 on both sides
cy - 3y - 7 +7 = 5d +7
= cy - 3y = 5d +7
Step 3: Factor out y
y(c - 3) = 5d + 7
Step 4: Divide both sides by c-3
y(c - 3) / c - 3 = 5d+7 / c-3
Your answer for this should be
y = 5d + 7 / c - 3

The correlation coefficient r between an employee’s age, x, and yearly salary, y, is 0.633. What percent of the variation in yearly salaries can be explained by differences in the employees’ ages? 31.7% 63.3% 15.8% 40.1%
Answer:
The answer is 40.1%
Step-by-step explanation:
I just took the test
The variation in the yearly salaries can be explained by the differences in employee ages up to 40.1%.
When given the correlation coefficient of two variables, you can find out how much of the variation in the dependent variable can be explained by the independent variable by the formula:
= (Correlation coefficient)² x 100%
= 0.633² x 100%
= 0.4007 x 100%
= 40.1%
In conclusion, 40.1% of the variation in salary can be explained by age.
