A particle travels 24.6 km in 30 minutes. Find the
speed of the particle in
(i) km/h,
(ii) m/s.
Answer:
See the solutions below
Step-by-step explanation:
Given data
Distance = 24.6km
in meters= 24.6*1000= 24600m
time= 30 minutes
in seconds= 30*60= 1800
int hours= 0.5 hour
speed of the particle in
(i) km/h= 24.6/0.5= 49.2 km/h
(ii) m/s.= 24600/ 1800= 13.66 m/s

find the value of x in the diagram below
Answer:
x = 12
Step-by-step explanation:
ZY is a midsegment and is half the measure of SQ, that is
x + 2 = [tex]\frac{1}{2}[/tex] (3x - 8) ← multiply through by 2 to clear the fraction
2x + 4 = 3x - 8 ( subtract 2x from both sides )
4 = x - 8 ( add 8 to both sides )
12 = x

In 2019, Chris made $142,000 as a dentist. Social Security tax was 6.2% to a maximum income of $132,900.
Medicare tax was 1.45% of all income. How much did Chris pay in FICA Taxes?
Type your answer
Answer: $10,298.80
Step-by-step explanation:
Chris made more than the limit required for the Social Security tax so his Social Security tax will be based on the maximum amount of $132,900.
His Social Security tax is therefore:
= 6.2% * 132,900
= $8,239.80
There are no limits for Medicare so Chris will pay taxes on the whole amount he earned of $ 142,000.
Medicare = 1.45% * 142,000
= $2,059
FICA tax = Social security + Medicare
= 8,239.80 + 2,059
= $10,298.80

Answer:
i think im to late sorry
Step-by-step explanation:
You earn $11 per hour working at a grocery store during the summer. The function p(x)=11x represents the amount you earn for working x hours.
a. You work 18 hours. How much do you earn?
b. How many hours do you have to work to earn $275?
plz help me!!!
Answer:
A. $198 and B. 25
Step-by-step explanation:
11 × 18 is 198, which is the first answer.
If you take 275 and divide it by 11, you get how many hours you have worked, which would be 25. :)
Answer:
a. $198
b. 25 hours
Step-by-step explanation:
a. You earn $11 per hour, and so if you work 18 hours, you multiply "11 x 18" to find out how much money you would make during that time period.
b. To find out how many hours you are required to work to be paid $275, you simply need to divide by 11, seeing as how that is how much you would be paid per hour. So, the equation would look like this: "275/11 = 25"
