A raindrop fallsat a rate of 4/50mile in 1/20hour. At this rate, how far will the raindroptravelin 1 hour?(60 minutes)
Answers
Answer:
Step-by-step explanation:
1/20 hour = 5 minutes
(We can now call 1/20 of an hour 5 minutes)
If it falls 4/50 of a mile in 5 minutes (1/20 of an hour),
we do 4/50 * 12 because there are 12 5-minute intervals in an hour/
4/50 * 12 = 48/50 = 24/25 of a mile
Therefore, the raindrop will travel 24/25 of a mile in an hour.
The distance of the raindrop in an hour will be 24/25 miles.
What is speed?The speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance. Speed is a scalar quantity and is described by its magnitude only.
Given that A raindrop falls at a rate of 4/50 mile in 1/20 hour. The distance in an hour will be calculated as:-
If it falls 4/50 of a mile in 5 minutes ( 1/20 of an hour ),
Distance = 4/50 x 12
Distance = 4/50 x 12
Distance = 48/50
Distance = 24/25 of a mile
Therefore, the distance of the raindrop in an hour will be 24/25 miles.

What is the equation of the line shown on the graph?
A y=x
B y=4x
C Y= -x
D Y =1/4 X
Answers
Take two points from the graph and solve for the slope:
Let (x1, y1) = (2, 8)
(x2, y2) = (4, 16)
substitute these values into the slope formula:
m = (y2 - y1)/(x2 - x1)
m = (16 - 8) / (4 - 2)
m = 8/2
m = 4
Therefore, the slope is 4.
The y-intercept is the y-coordinate of the point (0, b) where the graph of the linear equation crosses the y-axis. The y-intercept is also the value of y when x = 0.
Looking at the graph, the line crosses at the point of origin, (0, 0). Therefore, the y-intercept, b = 0.
The correct answer is option B) y = 4x.

The Correct choice is D
For the function f(x) = -x+8, f(x-k) = f(x)+k. Option (D) is correct.
What is function?Function is a combination of different types of variable and constants.
A function is denoted by f(x).
The given function is,
f(x) = -x+8,
Substitute x= x+k in the given function,
f(x+k) = -(x+k)+8
f(x+k) = -x-k+8
f(x+k) = -x+8-k
Substitute -x+8= f(x) here,
f(x+k) = f(x)-k
Substitute x= x-k in the given function,
f(x-k) = -(x-k)+8
f(x-k) = -x+k+8
f(x-k) = -x+8+k
Substitute -x+8= f(x) here,
f(x-k) = f(x)+k
Hence, option (D) is correct.

Answer:
Step-by-step explanation:
1) Determining the nature of roots:
Quadratic equation: ax² + bx +c = 0
Find D (Discriminant) using the D = b² - 4ac
If D = 0 , then the two roots are equal.
If D > 0, then the equation has two distinct real roots.
If D < 0, then the roots are complex/ imaginary.
One can find the sum and product of the roots using the below mentioned formula.
1) sum of roots = [tex]\frac{-b}{a}[/tex]
2) Product of roots = [tex]\frac{c}{a}[/tex]
If sum and product of the roots are given, one can frame the quadratic equation by x² - (sum of roots)*x + product of roots = 0
2) i) x² - 6x + 9 = 0
a = 1 ; b = -6 and c = 9
D = (-6)² - 4 * 1 * 9 = 36 - 36 = 0
D = 0. So, two equal roots
ii) x² - 4x + 3 = 0
a = 1 ; b = -4 ; c = 3
D = (-4)² - 4 * 1 * 3 = 16 - 12 = 4
D > 0. So, two distinct real roots.
iii) x² - 4x - 3 = 0
a = 1 ; b = -4 ; c = -3
D = (-4)² - 4*1*(-3) = 16 + 12 = 28 > 0
D > 0. So, two distinct real roots.
iv) x² - 4x + 7 = 0
a = 1 ; b = -4 ; c = 7
D =(-4)² - 4 *1 *7 = 16 - 28 = - 12
D< 0. So, two imaginary/ complex roots.
Paul paid $663 for a new freezer. He paid for the freezer with his credit card, which has an interest rate of 15.28% compounded monthly, and made monthly payments for five years until the freezer was paid off. He kept the freezer for seven years, and it used an average of $2.14 of electricity per week. Paul made no other purchases or payments with his credit card until the freezer was paid off. Between the interest and the electricity, which component of the lifetime cost of the freezer was greater, and how much greater was it? (Round all dollar values to the nearest cent.)
a.
The interest cost $106.60 more than the electricity.
b.
The interest cost $173.24 more than the electricity.
c.
The electricity cost $489.76 more than the interest.
d.
The electricity cost $115.96 more than the interest.
Answers
Answer:
c
Step-by-step explanation:
The electricity cost $489.76 more than the interest.
Thus, option C is correct.
What is Interest cost?Interest cost is the total measure of interest a borrower pays on an obligation commitment over the existence of the getting. Interest is paid on the obligation notwithstanding reimbursement of head.
The formula will be:
I = A - P
I = 663(1 + 0.1528/12)^(5*12) - 663
I = 663(1 + 0.1528/12)^60- 663
I = 1416.51 - 663
I = $753.51
The bill for electricity for 7 years and 52 weeks per year will be
= 7 x 52 x 2.14
= $778.96
The electricity cost is bigger than the interest:
$778.96 is bigger than $753.51 by $25.45:
$778.96 - $753.51 = $25.45.
Therefore, option C is correct.

2323
Step-by-step explanation:
Mental math means to find a way to do this problem in your head without using paper, pencil or a calculator.
The question says there are 23 classes and each class is to collect 101 items.
The equation would be 23 x 101.
To do this in your head real quick, make the numbers easier to multiply.
Make the 101 items 100. That means you are telling each class to collect 1 less item or 23 less items total.
You can do this in your head real quick. 23 classes collecting 100 items is 2300 items.
You had each class collect 100 items instead of 101. That mean you didn't collect 23 items. So if you add those back in, you will get
2323 items.
