Josie is training for a race the ratio of the number of minutes she wants to the number of miles she wants is 2043 she plans to

guajiro [1.7K]

Answer:

Josie takes 0.93 minutes to run 2 miles.

Step-by-step explanation:

We are given the following in the question:

Ratio:

Number of minutes: Number of miles = 20:43

Josie wants to run 2 miles. We have to find the number of minutes she need to run to maintain the ration.

Let x be the number of minutes Josie run.

This can be done in the following manner:

$\dfrac{20}{43} = \dfrac{x}{2}\\\\\Rightarrow x = \dfrac{20}{43}\times 2\\\\\Rightarrow x = 0.93$

Thus, Josie takes 0.93 minutes to run 2 miles.

The interest rate r required to increase your investment p to the amount a in t years is found by . Find the interest rate r for

Dahasolnce [82]

Answer:

The interest rate was of 0.1173 = 11.73%.

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

$E = P*I*t$

In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

After t years, the total amount of money is:

$A = E + P$

In this problem, we have that:

$A = 10000, P = 8100, t = 2$

$A = E + P$

$10000 = E + 8100$

$E = 1900$

$1900 = 8100*I*2$

$I = \frac{1900}{8100*2}$

$I = 0.1173$

The interest rate was of 0.1173 = 11.73%.

The line parallel to x-3y=-12 that passes through (-3,4)

gulaghasi [49]

X-3y=12
3y=x-12
y=1/3x-4
parallel means same gradient, which is 1/3.
Use formula y-y1=m(x-x1), m=gradient and y1 is y coordinate of point and x1 is x coordinate of point.
y-4=1/3[x-(-3)]
y-4=x/3+1
y=x/3+5

Find mZLKM. м. M K/(3x – 70) 60° L mZLKM= l

Bingel [31]

Answer:

125

Step-by-step explanation:

( 3x - 70 ) is exterior angle.

60 and x are interior angles.

Formula : -

Exterior angle of a triangle

= Sum of two interior angles in a triangle

3x - 70 = x + 60

3x - x = 60 + 70

2x = 130

x = 130 / 2

x = 65

m∠LKM = 3x - 70

= 3 ( 65 ) - 70

= 195 - 70

m∠LKM = 125
