Answer:
169 units
13 units
The distance between the two points (4, 3) and (9, 15) will be 13 units. Then the correct options are A and D.
What is the distance between two points?Let one point be (x, y) and another point be (h, k).
Then the distance between the points will be
D² = (x - h)² + (y - k)²
The coordinate of the points is given below.
(4, 3) and (9, 15)
Then the distance between the two points (4, 3) and (9, 15) will be given as,
D² = (9 - 4)² + (15 - 3)²
D² = 5² + 12²
D² = 25 + 144
D² = 169
D = 13 units
The distance between the two points (4, 3) and (9, 15) will be 13 units. Then the correct options are A and D.

Weak battery is considered to be a part of routine
O A. wear and tear
O B. maintenance
O C. check
O D. inspection
Answer:
A. wear and tear
Step-by-step explanation:
A battery is generally expected to become weaker over time, as a consequence of the normal use of equipment. The presence of a weak battery would be found by a routine check, and replaced by routine maintenance.
The fact that a battery is weak would be considered the result of routine wear and tear

william runs 40 yards in 4.5 seconds. at the same pace how long will he take to run 100yards?
Answer:
11.25 seconds
Step-by-step explanation:
first, we need to figure how how far william can run per second
we can find this by 40 ÷ 4.5
= 8.889 per second
so we know that 8.889 • s (seconds) = 100
8.889s = 100 divide both sides by 8.889
s = 11.25 seconds
Answer:
William will take 11.25 seconds to run 100 yards
Step-by-step explanation:
Constant Rate
William runs 40 yards in 4.5 seconds. The rate of change of the distance is
[tex]\frac{40}{4.5}[/tex]
To run 100 yards, we divide by the rate obtained above:
[tex]\displaytstyle \frac{100}{\frac{40}{4.5}} =100*\frac{4.5}{40} =11.25[/tex]
William will take 11.25 seconds to run 100 yards
Elaine drives her car 180 miles and has an average of a certain speed. If the average speed had been 5mph more, she could have traveled 200 miles in the same length of time. What was her average speed?
Answer:
45 mph
Step-by-step explanation:
Using the equation d = rt, we can rearrange the equation to be t = d/r
Since the amount of time was the same, we can set d/r equal to each other for both speeds.
Let x represent the average speed.
[tex]\frac{d}{r}[/tex] = [tex]\frac{d}{r}[/tex]
[tex]\frac{180}{x}[/tex] = [tex]\frac{200}{x+5}[/tex]
Cross multiply and solve for x:
200x = 180x + 900
20x = 900
x = 45
So, the average speed was 45 mph

What are the coordinates of the image of point T(2,4) over the transformation D(1/2,R), where R(6,-2) is the center. X= ? Y= ?
9514 1404 393
Answer:
T'(4, 1)
Step-by-step explanation:
The dilation transformation around a center not the origin is ...
T' = k(T -R) +R . . . . for dilation factor k and center R
This can be simplified to ...
T' = 1/2T -1/2R +R = 1/2T +1/2R = (T +R)/2
Using the given point values, we find the image point to be ...
T' = ((2, 4) +(6, -2))/2 = (8, 2)/2 = (4, 1)
The image point is T'(4, 1).

Suppose a loaded die has the following probability model: If this die is thrown and the top face shows an odd number, what is the probability that the die shows a 1
Answer:
the probability is 0.6
Step-by-step explanation:
The computation is shown below:
Let us assume the X would be the number appear on the top face
Now
= P(X = 1) ÷ P(X = 0)
= 0.3 ÷ 0.3 + 0.1 + 0.1
= 0.3 ÷ 0.5
= 0.6
hence, the probability is 0.6

A.) A paint store sells exterior for $35.75 a gallon and paint rollers for $6.00 each. Write an equation in standard form for the number of gallons p of paint rollers r that a customer could buy with $190.
B.) Use your equation to determine the number of gallons of paint needed if a customer bought 6 rollers
The total price for the gallons of paint will be 35.75p
The total price for the rollers will be 6r
So the equation if the customer have 190 will be
price for gallons of paint + price for rollers = 190
35.75p + 6r = 190
(This is the equation)

The function f(x) =5x coverts x nickels to pennies. Find a function that converts X Pennys to Nichols then convert 50 pennies to Nichols. 
Answer:
[tex]f'(x) = \frac{1}{5}x[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 5x[/tex] --- Nickel to Penny
Required
Determine the function that converts penny to nickel
This question implies that we determine the inverse of the function.
We have:
[tex]f(x) = 5x[/tex]
Represent f(x) with y
[tex]y = 5x[/tex]
Swap the positions of x and y
[tex]x = 5y[/tex]
Make y the subject by dividing both sides by 5
[tex]\frac{1}{5}x = \frac{5y}{5}[/tex]
[tex]\frac{1}{5}x = y[/tex]
[tex]y =\frac{1}{5}x[/tex]
Replace y with f'(x)
[tex]f'(x) = \frac{1}{5}x[/tex]
Hence, the function that converts x pennies to nickels is [tex]f'(x) = \frac{1}{5}x[/tex]
A civil servant had a salary of Rs. 9600. Tax up to
Rs. 85000 per year would be exempted. If he paid
Rs. 377.50 as a tax per month, how much percent of
tax was imposed ?
(Ans: 15 %
Answer:
Step-by-step explanation:
The question is misleading. It was not specified that his salary is Rs 9,600 per month. That is 115,200 yearly. Of that, 115,200- 85,000 = 30,200 is taxable.
tax = Rs 377.50/month = Rs 4,530/year
4,530/30,200 = 0.15 = 15%

A soccer team gets three points for a win, one point for a tie, and zero points for a loss. The team plays ten games and has three more wins than losses. What is the greatest possible number of points the team could have?
Answer: 19.
Step-by-step explanation:
The highest you can go is 6 and 3 because you can't do 7 and 4. 6 wins would add up to 18 points. The one game that is missing we can say could be a tie, which would add 1 point, making it 19 possible points.
Answer:
Highest number of wins and losses can only be 6 & 3 and if u take 7 & 4 as taking 7&4 will make total 11 and we know that there was only 10 games.
So we can conclude like this
Number of wins: 6
Number of losses: 3
Number of draws: 1
Thus the points will be, (6*3)+(3*0)+(1*1)
18+0+1
=19 points
With a coupon, you can get a pair of shoes that normally cost $84 for only $72. What percentage was the discount. Please give the step by step explanation!
Answer:
14.28%
Step-by-step explanation:
Given that,
You can get a pair of shoes that normally cost $84 for only $72.
We need to find the discount percentage. So, it can be calculated as follows :
[tex]\%=\dfrac{84-72}{84}\times 100\\\\\%=14.28\%[/tex]
So, the required percentage is 14.28%.
