Betsy drove from london to wolverhampton.it took her 2.5 hours at an average speed of 56 miles per hour.Mac drove the same journy by motor bike.It took him 2 hours.Assuming that both took the same route,work out Mac's average speed in mph.
Answer:
44.8 mph
Step-by-step explanation:
Betsy drove from london to wolverhampton.it took her 2.5 hours at an average speed of 56 miles per hour.Mac drove the same journy by motor bike.It took him 2 hours.Assuming that both took the same route,work out Mac's average speed in mph.
The above question is solved using Proportion method
2.5 hours = 56 mph
2 hours = x mph
Cross Multiply
2.5 hours × x mph = 2 hours × 56 mph
x mph = 2 hours × 56 mph/2.5 hours
x mph = 44.8 mph
Therefore, Mac's average speed = 44.8 mph

What is m∠Q=?
What does m∠R=?
What is m∠S=?
Answer:
89°, 123°, 91°Step-by-step explanation:
Inscribed angle is half of the intercepted arc.
m∠Q = 1/2(mPS + mRS) = 1/2(41° + 137°) = 89°Opposite angles are supplementary.
Supplementary angles sum to 180°.
m∠R = 180° - m∠P = 180° - 57° = 123°m∠S = 180° - m∠Q = 180° - 89° = 91°Simplify.

Mila went shopping for a new pair of pants because of a sale. The store was offering a 30% discount. What number should she multiply the prices on the tags by to find the price she would have to pay, before tax, in one step?
Answer:
Mila must multiply the price by 0.7 to obtain the price with the discount made.
Step-by-step explanation:
Since Mila went shopping for a new pair of pants because of a sale, and the store was offering a 30% discount, to determine what number should she multiply the prices on the tags by to find the price she would have to pay, before tax, in one step, the following calculation must be performed:
100 (price without discount) - 30 (discount) = X
100 - 30 = X
70 = X
70/100 = 0.7
Thus, Mila must multiply the price by 0.7 to obtain the price with the discount made.

How do I find the slope of a line?
Answer:
In order to find the slope of the line, find two points that are on the line and use the equation: m=(y2-y1)/(x2-x1). The 2 points should be whole numbers.
Answer:
Step-by-step explanation:
y2-y1
he first equation you need is m= ---------
x2-x1
x1 , y1 x2, y2
then you label the point like this ex: ( 2, -5) (1, 3)
and then place them in the places of the original eqatuion and you get your answer. but then you can simplify if you need too.

Points given:
M(-5, -2) - midpoint A(-3, 4) - endpoint B(x, y) - endpointUse midpoint formula to find the coordinates of B:
x = (x1 + x2)/2, y = (y1+ y2)/2Substitute known values and solve for x and y:
-5 = (-3 + x)/2 ⇒ -10 = -3 + x ⇒ x = -10 + 3 ⇒ x = -7 -2 = (4 + y)/2 ⇒ -4 = 4 + y ⇒ y = -4 - 4 ⇒ y = -8Point B is:

Step-by-step explanation:
Water flows from a faucet into a bathtub at a constant rate of 2.5 gallons per minute. The bathtub initially has 5 gallon of water in it.
Complete question :
Water flows from a faucet into a bathtub at a constant rate of 2.5 gallons per minute. The bathtub initially has 5 gallon of water in it. Write a function to represent the situation.
Answer:
f(x) = 2.5x + 5
Step-by-step explanation:
A function which could be used to represent the situation is the slope - intercept function ;
The constant rate of water flow per minute could represent the slope of the function, which is the change in y per unit change in x ;
The intercept is the initial water level in the bath tub = 5 gallons
Slope intercept equation:
y = mx + c
m = slope ; c = intercept
The water in the bathtub as a function of x, number of minutes is ;
f(x) = 2.5x + 5
Solve for x. Round to the
nearest tenth.

Lydia invested $83,000 in an account paying an interest rate of 6.7% compounded
monthly. Assuming no deposits or withdrawals are made, how long would it take, to
the nearest year, for the value of the account to reach $210,100?
Answer:
14
Step-by-step explanation:
The required time for Lydia's account to reach $210,100 is 13.9 years.
What is compound interest?Compound interest is the interest on deposits computed on both the initial principal and the interest earned over time.
First, convert R as a percent to r as a decimal
r = R/100
r = 6.7/100
r = 0.067 per year,
Then, solve the equation for t
t = ln(A/P) / n[ln(1 + r/n)]
t = ln(210,100/83,000) / ( 12 × [ln(1 + 0.067/12)] )
t = ln(210,100/83,000) / ( 12 × [ln(1 + 0.0055)] )
t = 13.9 years
Thus, the required time for Lydia's account to reach $210,100 is 13.9 years.

What does the value of the mean absolute deviation tell you about the spread of the data? HURRY PLEASE ILL GIVE 35 POINTS
Answer:
The Mean Absolute Deviation (MAD) of a set of data is the average distance between each data value and the mean. The mean absolute deviation is the "average" of the "positive distances" of each point from the mean. The larger the MAD, the greater variability there is in the data (the data is more spread out).
