Answer:

<h2>length = 44 in, width = 20 in</h2>

Step-by-step explanation:

\text{The formula of a perimeter of a rectangle:}\\\\P=2(l+w)\\\\l-length\\w-width\\\\\text{We have}\ l=(w+24)\ in,\ P=128\ in\\\\\text{Substitute:}\\\\128=2(w+24+w)\qquad\text{divide both sides by 2}\\\\64=2w+24\qquad\text{subtract 24 from both sides}\\\\40=2w\qquad\text{divide both sides by 2}\\\\20=w\to w=20\ in\\\\l=20+24=44\ in

Which of the following sample types should you always regard as unreliable? A) voluntary response samples 18) 9 simple random sa
Inessa [10]

Answer:

The type of sample that can be considered unreliable is type (a), in which responses are voluntary.

Step-by-step explanation:

The type of sample that can be considered unreliable is type (a), in which responses are voluntary.

It can be considered unreliable because being voluntary, the answers will give a biased result and the analysis will not be valid.

The rest of the options, if the necessary collections are taken, are samples that can be considered reliable.

The hypotenuse of a right triangle is 26 mm. One leg of the right triangle is 10 mm. What is the length of the other leg? (4 poi
PIT_PIT [208]

Answer:

24 mm

Step-by-step explanation:

Since it is a right triangle, we can use Pythagorean theorem

a^2+b^2=c^2

where a and b are the legs, and c is the hypotenuse.

We know one of the legs is 10, and the hypotenuse is 26, so we can substitute 10 in for a, and 26 in for c.

10^2+b^2=26^2

Solve the exponents

100+b^2=676

Now, solve for b. To do this, get b by itself.

First, subtract 100 from both sides

100-100+b^2=676-100

b^2=576

Take the square root of both sides

\sqrt{b^2}=\sqrt{576}

b=24

So, the other leg is 24 mm
