Answer:
A. 67.8%
Step-by-step explanation:
the total number of occurences are 202
Now the total number of occurencess for 4 and below are 137
So Heres the quickest way to do it: Divide 137 by 202 then multiply it by 100 being 100%
Then you would get 67.8, then well put the percent sign behind it.
Answer:
Mr Singleton will only need $198 to buy calculator for the 9 student without one. Therefore run fundraiser to raise $1000 for this is No it is much too high
Step-by-step explanation:
If there are 29 student in Mr Singleton class, and 18 has calculator. then those without calculator will be
29 - 18 = 9
if each calculator costs $22, then to get calculator for them all, Mr Singleton will need
$22 × 9 = $198
If Mr Singleton want to estimate $1000 for this at fundraiser, no it is much too high
Answer:
∠STU = 69°
Step-by-step explanation:
The angle with vertex T is called an "inscribed angle." It intercepts arc SU. The relationship you are asked to remember is that the measure of the inscribed angle (T) is half the measure of the arc SU.
Point V is taken to be the center of the circle. The angle with vertex V is called a "central angle." It also intercepts arc SU. The relationship you are asked to remember is that the measure of the central angle (V) is equal to the measure of arc SU.
__
Using these two relationships together, we realize angle V is twice the measure of angle T:
∠SVU = 2×∠STU
18x +12° = 2(18x -57°) . . . . . . relationship between the marked angles
18x +12° = 36x -114° . . . . . eliminate parentheses
126° = 18x . . . . . . . . . . . add 114°-18x
∠STU = 18x -57° = 126° -57°
∠STU = 69°

<em>Additional comment</em>
You may notice we did not solve for x. We only needed to know the value of 18x, so we stopped when we found that value. (Actually, we only need the value of 18x-57°. See below.)
__
<em>Alternate solution</em>:
(18x +12°) -(18x -57°) = 18x -57° . . . . . . . subtract 18x -57° from both sides of the first equation.
69° = 18x -57° . . . . . simplify. This is the answer to the problem.
40 x 0.08875 = 3.55
40 + 3.55 = 43.55
the sum is $43.55
