S part of a statistic project, a math class weighed all the children who were willing to participate as shown below.
How many children weighed less than 50 pounds?
Answer:
18 children weighed less than 50 pounds.
Step-by-step explanation:
Ok, adding into the explanation what the heck this kind of a table is. The "stem" column is the tens place of each of the children's weights. The "leaf" is the ones digit of each of the children's weights. So in the row where the stem is 2, there were 2 kids weighing 23 and 25 pounds.
For your question, we have to add up how many students have a weight with a "stem" less than 5, because that's where 50 pounds starts.
8 + 2 + 5 + 3 = 18 children weighed less than 50 pounds.
If CosA= sqrt 3/2, what is TanA?
Answer:
√(3)/3
Step-by-step explanation:
cos(A) = adj./hyp.
adj. = √(3) or √(3)/2
hyp. = 2 or 1
use unit circle:
hyp. = 1
adj. = √(3)/2
use pythagorean theorem c² - b² = a²
1² - (√(3)/2)² = 1 - 0.75 = 0.25
a² = 0.25
a = √(0.25)
a = 0.5
tan(A) = opp./adj.
tan(A) = 0.5/(√(3)/2)
tan(A) = 1/√(3)
rationalize
tan(A) = √(3)/3
A cell phone company expects that every 2 out of 25 cell phones will have some formof defect. At this rate, how many cell phones out of 500 will be expected to have a defect?
Answer: 40 phones
Step-by-step explanation:
The company expects that every 2 out of 25 phones will have some form of defect.
In percentage terms, this is:
= 2 / 25 * 100%
= 8%
If there are 500 phones therefore, the defected phones would still be the same percentage and the actual number would be:
= 8 % * 500
= 40 phones

Geeta saves 18% of her monthly salary. If she spends Rs.10250 per month, what is her monthly salary? Please explain by step by step procedure.
Answer:
Rs.12500
Step-by-step explanation:
18% = saved
100 - 18 = 82%(used salary)
82% = 10250
100% = ?
100 × 10250 = 1025000
1025000 ÷ 82 = Rs.12500

Which of the following tables best represents the relationship between p and f in the equation p = 3.5f?
Answer:
A
Step-by-step explanation:
The image shows the angles formed by a pair of scissors. When the scissors are closed, m∠1 = 0°. As the scissors are opened, the measures of all four angles change in relation to each other.
Describe how the measures change as m∠1 increases from 0° to 180°.
Angle 3 is a vertical angle of angle 1 and will always be identical to what angle 1 is.
Angle 2 and angle 4 are supplementary angles to angle 1 and will always be the difference between 180 and what angle 1 is.
For example if angle 1 was 45 degrees, angle 3 would also be 45 degrees and angle 2 and angle 4 would be 180-45 = 135 degrees.

if 20% of a number is 386, what will be 30% of the same number
if the 20% of a number is 386, what will be 30% of the same number
Answer will be 157
If 20% of a number is 386, 30% of the same number is 579
How to determne the number?Let the number be x.
So,we have:
20% * x = 386
Express 20% as 0.20
0.20 * x = 386
Divide both sides by 0.20
x = 1930
30% of the number is represented as:
30% * 1930
Evaluate the product
30% * 1930 = 579
Hence, 30% of the same number is 579
