Answer:
20 people
Step-by-step explanation:
Take the amout of bowls (25) and divide by the ratio (5)
25/5=5
Multiply 5 *4 = 20
25 bowls to 20 people = 25/20 = 5/4
Angle-5 and angle-7 are 'vertical angles', so they're equal,
and we can write ...
<u>10x- 9 = 9x</u>
Subtract 9x from each side: x - 9 = 0
Add 9 to each side: <u> x = 9</u>
Now that we know what 'x' is, we can find the size of Angles-5 and -7 .
Angle-7 = 9x = 81° .
Now look at Angle-6 ... the one that's the answer to the problem.
Angle-6 and -7 together make a straight line, so they must
add up to 180°.
<u>Angle-6 + 81° = 180°</u>
Subtract 81° from each side: Angle-6 = <em>99° .</em>
<span>1. The highest speed is 39 mph.
2. 50 percent of the students drove between 15 and 28 mph.
3. A box and whisker plot shows the median speed.
4. 20 is the median speed for this data set.
5. A box and whisker plot is helpful in plotting variations in data and making it easy to read. It is also useful when there are multiple sets of data.</span>
Parallel is when the lines go the same direction and never touch whereas perpendicular lines are when the lines cross each other so the they are like a plus sign with all 90 degree angles. Hope i helped.
