If it takes a sloth 10 minutes to climb 7.5 feet what’s its climbing speed in miles per hour

Answer:

.009 miles/hour

Step-by-step explanation:

$\frac{7.5}{10}\frac{feet}{minutes} * \frac{1}{5280} \frac{miles}{feet} *\frac{60}{1}\frac{minutes}{hour}$

This is the method you should take with unit conversions in general, just set up fractions so the units cancel out, like the 7.5 feet cancels out with the feet in the 1/5280 so miles is left on top.

Answer:

$50

Step-by-step explanation:

If the original price was $10 more than the sale price, so we know that in this case, 20% = $10. Because 20% is equivlalent to $\frac{1}{5}$ , multiply $10 by 5 to get the answer of $50.

If your starting salary were $40,000 and you received a 3% increase at the end of every year for 15 years, what would be the tot

Dmitry [639]

T = 40000 + 40000(1.03) + 40000(1.03)^2 + ... + 40000(1.03)^15

Multiply the above equation by 1.03 giving

1.03(T) = 40000(1.03) + 40000(1.03)^2 + 40000(1.03)^3 + ... + 40000(1.03)^15 + 40000(1.03)^16

Now subtract the first equation from the second to give

0.03T = 40000(1.03)^16 - 40000

0.03T = 40000(1.03^16 - 1)

0.03T = 24188.26

T = 24188.26 / 0.03 = $806275.25

In Exercises 15-18, find the measure of the exterior angle.

valina [46]

Answer:

The measure of the exterior angle is 92 degrees

Step-by-step explanation:

Problem 16)

we know that

An exterior angle of a triangle is equal to the sum of the opposite interior angles

so

In this problem

$(2x-2)\°=x\°+45\°$

solve for x

$2x-x=45+2$

$x=47\°$

Find the measure of the exterior angle

$(2x-2)\°=(2(47)-2)=92\°$

What is the slope of the line represented by the equation below?y=-2/3x+3 A-2/3 B. 2/3 C.2 D.x

Black_prince [1.1K]

ANSWER

A.

$- \frac{2}{3}$

EXPLANATION

The given equation is

$y = - \frac{2}{3}x + 3$

This equation is already in the form:

$y =mx + b$

This is called the slope-intercept form.

The slope is

$m = - \frac{2}{3}$

and the y-intercept is 3.

The correct answer is A.

In a situation where the line is not given in the slope intercept form, then you must rewrite in this form before comparing.
