Problem 10

<h3>Answer: 80 degrees</h3>

Work Shown: 80-0 = 80

You subtract the values on the protractor where the two angle arms line up.

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

Problem 11

<h3>Answer: 45 degrees</h3>

Work Shown: 45-0 = 45

Same idea as problem 10

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

Problem 12

<h3>Answer: 83 degrees</h3>

Work Shown: 128-45 = 83

Same idea as the others. The arm TS isn't fully on 130 degrees, and it's a bit short of it. It looks to be about 128 degrees or so.

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

Problem 13

<h3>Answer: 35 degrees</h3>

Explanation: Luis forgot to subtract the value of each arm of the angle. So he should have done 80-45 = 35. The answer would be 80 degrees if arm TQ was at 0 degrees (so 80-0 = 80), but instead TQ is at 45 degrees.

For the first figure the Circumference of the circle is: 5.3 $\ip$ $\pi$ cm.

For the second figure the Circumference of the circle is: 80 $\ip$ $\pi$ inch.

<h3>What is Circumference of the Circle?</h3>

The circumference of a circle is defined as the linear distance around it.

i.e., $C= 2 *\pi*r$

For First Figure,

Circumference of the circle:

$= 2 *\pi*r$

$= 2 *\pi* \frac{5.3}{2}$

$= 2 *\pi*2.65$

$Circumference= 5.3*\pi cm$

For the second Figure,

Circumference $= 2 *\pi*r$

$= 2 *\pi*40$

$= 80 *\pi$

$Circumference =80\pi \;inch$

For the first figure the Circumference of the circle is: 5.3 $\ip$ $\pi$ cm.

For the second figure the Circumference of the circle is: 80 $\ip$ $\pi$ inch.

The costs of 5 similar digital cameras and 3 similar video cameras is $3,213. Each video camera costs 4 times as much as each di

mariarad [96]

Let,
digital cameras be "x"
video cameras be "y"
Now,
According to the question,
5x + 3y = $3,213..................................................equation (1)
y = 4x..................................................................equation (2)

Taking equation (1)
5x + 3y = $3,213
Substituting the value of "y" from equation (2), we get,
5x + 3(4x) = $3,213
5x + 12x = $3,213
17x = $3,213
x = $3,213 / 17
x = $189

Taking equation (2)
y = 4x
Substituting the value of "x", we get,
y = 4 ($189)
y = $756

Now,
John buys a digital and a video camera. So, it costs him ($189 + $756) = $945
