Janice works at a cell phone company. She wants to make a presentation to her team about the features of a new phone. She makes a scale drawing of the phone using a scale of 1 inch to 0.5 centimeter. The length of the scaled drawing is 28 inches, and its width is 15 inches. What are the actual dimensions of the phone?The length is 14 inches, and the width is 7.5 inches.
The length is 56 inches, and the width is 30 inches.
The length is 56 centimeters, and the width is 30 centimeters.
The length is 14 centimeters, and the width is 7.5 centimeters.
The length is 12 centimeters, and the width is 5.5 centimeters.

Answers

If 1 inch represents 0.5 centimeter, then 28 inches will represent 28 * 0.5 = 14 centimeters and 15 inches will represent 15 * 0.5 = 7.5 centimeters.

The actual dimensions of the phone is: the length is 14 centimeters and the width is 7.5 centimeters.

Answer:

The length is 14 centimeters, and the width is 7.5 centimeters.

Isosceles triangle with one angle of 100. What would most likely be the other angles?

Answers

Isoceles triangles have one pair of congruent base angles opposite their congruent sides. Also, the angles in a triangle add up to 180°. Therefore, we can set up this equation:

100 + x + x = 180

(we know it's not the 100° angle that has a congruent match because that would cause the total angle measure to go above 180°)

100 + 2x = 180
Subtract 100 from each side.
2x = 80
Divide by 2.
x = 40°

Both of the other angles would be 40°.

There's no "most likely" about it.

==> Every isosceles triangle has two equal angles.
==> In this one, the 100-degrees angle is either one of the two equal angles,
or else it isn't.
==> If the 100 is one of the two equal angles, then the other one is also 100,
and the sum of the angles in this triangle ... even without the third one ...
is already more than 180 degrees.
==> So the 100 CAN'T be one of the equal angles. It must be the third angle.

-- Now there are 80 degrees left over to split between the other two angles,
which ARE equal.

-- The other two angles, which are not 100 degrees, MUST be 40 degrees each.

Not probably, not maybe, not could-be, and not "most likely". They must be.

If you buy 10 printers for your office and each printer costs $199, what is your cost for all 10?a. $2,990
b. $1,999
c. $1,990
d. $2,999

Answers

You buy: 10 printers
Each cost: $199
Total cost = ?

199 × 10 = total cost
199 × 10 = 1990
$1,990

This proves that c. $1,990 is your answer.
