If q, s, and t are all different numbers, is q < s < t ?

1 answer:

7 0

It very well could be, but not necessarily. What if q = 10, s = 8, and t = 6?

The statement is that q is less than s, and s is less than t (which therefore also means q is less than t).

However, when we substitute (replace) all the letters with the values we assigned them, we can find that the expression becomes:

10 < 8 < 6

This clearly isn’t right, as 10 is the greatest number there, and 8 is definitely less than 10 and greater than 6.

If you’re looking for an equation for both of these, Bob’s rentals would be 20+2m and Bella’s would just be 6m. If you are trying to figure out how many movies it would take to be the same, set up the equation 20+2m=6m and solve. Im not exactly sure what you are asking for but I hope this helps.

Identify the percent of change as an increase or decrease. Then find the percent of change. Round to the nearest tenth of a perc

bazaltina [42]

I'll do the first two problems to get you started. All problems shown will use the same formula.

===========================================

Problem 4

The formula to use is

C = 100*(B-A)/A

where

A = old value

B = new value

C = percent change

In this case, A = 12 and B = 36, so

C = 100*(B-A)/A

C = 100*(36-12)/12

C = 100*(24/12)

C = 100*2

C = 200%

We have a 200% increase. It is an increase because the value of C is positive.

===========================================

Problem 5

Use the same formula as in the previous problem. This time,

A = 75 is the old value

B = 25 is the new value

C = 100*(B-A)/A

C = 100*(25-75)/75

C = 100*(-50/75)

C = 100*(-2/3)

C = -66.6667%

C = -66.7%

The value of C is negative, so we have a percent decrease of roughly 66.7%

If a triangle is 12 inches high and has a 20 inch long hypotenuse then how wide is it?

Ber [7]

Answer:

The triangle should be 16 inches wide.

Step-by-step explanation:

$\text {Use the Pythagorean Theorem to solve for the leg.}\\a^2 + b^2 =c^2$

What we know:

One of the legs measures 12 inches.

The hypotenuse is 20 inches.

We need to solve for b. Solving for a while b is 12 would also be acceptable.

$12^2 + b^2 = 20^2 \text { OR } a^2 +12^2=20^2$

We will use the first equation.

$12^2 + b^2 = 20^2\\12 * 12 = 144\\20 * 20 = 400\\\\\boxed {144 + b^2 = 400}$

$\text {Subtraction property of equality: }\\144-144+ b^2 = 400-144\\\boxed {b^2 = 256}\\\\\text {Take the square root of 256: }\\\sqrt{256}=\sqrt{b^2} \boxed {16 = b}$

The triangle should be 16 inches wide.
