A man drove his car at 80km per hr for 1 and a quarter hrs .He rested for 45mins and then covered 240km, at the same time. Calculate his average speed for the whole journey
Answer:
Probably 128 km/h, but maybe 98.5 km/h. See below.
Step-by-step explanation:
What does "at the same time" mean?
If it means that he covered the 240 km in the same time as he convered the 80 km, then this is how you solve it:
80 km in 1.25 hour
240 km in 1.25 hour
Total distance: 80 km + 240 km = 320 km
Total time: 1.25 hour + 1.25 hour = 2.5 hour
average speed = (total distance)/(total time) = 320 km / 2.5 hour = 128 km/h
If it means he covered the 240 km in the same time he covered the 80 km plus the rest, then this is how you solve it:
80 km in 1.25 hour
240 km in 1.25 hour + 45 min = 240 km in 1.25 houir + 0.75 hour = 240 km in 2 hour
Total distance: 80 km + 240 km = 320 km
Total time: 1.25 hour + 2 hour = 3.25 hour
average speed = (total distance)/(total time) = 320 km / 3.25 hour = 98.5 km/h
A sweater is marked 30% off the original price. The original price was $37.50. What is the sale price of the sweater before sales tax?
(I will give brainliest if you show your work)!!
Answer:
$26.25
Step-by-step explanation:
To find the discounted price, subtract the discount amount from the original price. The amount of the discount is the product of the discount rate and the original price.
__
discounted price = original price - (original price) × (discount rate)
You can calculate it this way, or you can factor out the original price:
discounted price = (origina price) × (1 - discount rate)
= $37.50 × (1 -0.30) = $37.50 × 0.70 = $26.25
The sale price of the sweater is $26.25.
__
Additional comment
The amount of the discount is ...
$37.50 × 0.30 = $11.25
which makes the discounted price be ...
$37.50 -11.25 = $26.25
Write a propotion that can be used to convert 50 meters into kilometers. Then solve
Answer:
0.05km
Step-by-step explanation:
There are 1000 meters in a single kilometer. Using some dimensional analysis, we get set up the following expression:
[tex]\frac{50}{1} \frac{meters}{1}\frac{1}{1000} \frac{kilometers}{meters}[/tex]
The meters will cancel leaving the units of kilometers:
[tex]\frac{50}{1000} km=0.05km[/tex]
Set up a system of linear equations to represent the scenario. Solve the system by using Gaussian elimination or Gauss-
Jordan elimination.
Sylvia invested a total of $27,000. She invested part of the money in a certificate of deposit (CD) that earns 3% simple

If 43,560 square feet equals one acre, how many acres are in one square mile?
Answer: 640
Step-by-step explanation:
How many acres are there in 1 square mile? There are 640 acres in 1 square mile. To convert from square miles to acres, multiply your figure by 640 (or divide by 0.0015625) .
Answer:
640 acres²
Divide the area value by 68
[tex]43,560 / 68 = 640[/tex]
or
[tex]1~mile^2 * 640 = 640[/tex]
you multiply the area value by 640 for each square mile, since there is only one square mile, the answer is 640

Which account recorded a greater percentage change in amount of money over the previous year? Justify your answer. (5 points)
2
Answer:
Account A: Decreasing at 8 % per year
Account B: Decreasing at 10.00 % per year
Account B shows the greater percentage change
Step-by-step explanation:
Part A: Percent change from exponential formula
f(x) = 9628(0.92)ˣ
The general formula for an exponential function is
y = ab^x, where
b = the base of the exponential function.
if b < 1, we have an exponential decay function.
ƒ(x) decreases as x increases.
Account A is decreasing each year.
We can rewrite the formula for an exponential decay function as:
y = a(1 – b)ˣ, where
1 – b = the decay factor
b = the percent change in decimal form
If we compare the two formulas, we find
0.92 = 1 - b
b = 1 - 0.92 = 0.08 = 8 %
The account is decreasing at an annual rate of 8 %.The account is decreasing at an annual rate of 10.00 %.
Account B recorded a greater percentage change in the amount of money over the previous year.

What is the area of this figure?
Answer:
35 cm^2
Step-by-step explanation:
First find the area of a square by multiplying its side lengths together: 5 * 5 = 25 cm^2.
Now find the area of the triangle by multiplying the base by the height and dividing by 2: 4 * 5 / 2 = 10 cm^2.
Therefore the total area of the figure is 25 + 10 = 35 cm^2.
Corrine picked 1/4 gallon of blackberries. She poured the berries equally into 4 containers. What fraction of a gallon is in each container?
Answer:
1/16
Step-by-step explanation:
In the starting, Corrine had 1/4 gallon of blackberries. Now, she poured the berries equally into 4 containers. Therefore, the amount of berries in each container is:1/4 : 4=1/16
Thus, each container has 1/16 of a gallon of blackberries.
Answer:
1/16 th of a gallon in each container.
Step-by-step explanation:
That would be 1/4 divided by 4.
1/4 / 4

Ciera can swim 400 meters in 1 minute and 20 seconds. What is Ciera’s average rate in meters per second?
Answer:
5 meters per second.
Step-by-step explanation:
There are 60 seconds in 1 minute:
1 minute 20 seconds = 60 seconds + 20 seconds = 80 seconds.
Divide the amount of meters swam (400) with the total amount of seconds used (80) to get the average meters per second:
(400 meters)/(80 seconds) = 5 meters/second.
5 is your answer.
~
Answer:
5 MPS
Step-by-step explanation:
If Ciera can swin 400 meters in 1 minute and 20 seconds,
400 meters = 1 minute 20 seconds (1 1/3 minutes).
Divide both sides by 1 1/3.
400/ 1 1/3 = 300
Since it asks in seconds, divide by 60.
300/60=5

Equation:
C = 1.75x + 5 25
A 22-mile ride costs $43.75.
Step-by-step explanation:
Because there is a flat fee of 5.25, only the first two equations could possibly be correct.
Then check with the examples given. If a 7 mile ride costs 17.50, the second equation cannot possibly be right. 7 miles times over $5 per mile will cost more than $35 not even including the flat fee.
Check:
1.75(7) + 5.25 = 17.50
and
12(1.75) + 5.25 = 26.25
So, the correct equation is
C = 1.75x + 5.25
Next use this equation to find the cost of the 22 mile ride.
1.75(22) + 5.25
= 43.75
Sheila is 1.7 m tall her son is 109 cm tall how many meters taller is Sheila than her son
Answer:
61 cm or 0.61 m
Step-by-step explanation:
1. One meter is 100 cm, so you multiply 1.7 meters by 100 to get 170 cm.
2. Now that they are in the same units, to get their difference in height, you subtract Sheila's height from her son's (170 - 109) and get 61 cm.
3. Convert it back to meters by dividing by 100 and you get their difference in height in meters, 0.61 m.
Answer:
0.61
Step-by-step explanation:
One cenimeter is equivalent to 0.01 meter.
109cm • 0.01 = 1.09m
1.7m - 1.09m = 0.61m
Sheila is 0.61m taller than her son

Answer:
17.51
Step-by-step explanation:
this is a right triangle, so sohcahtoa applies
we want x
relative to the angle, x is opposite of it and 25 is adjacent to it (the hypotenuse is the other side)
the formula that combines opposite and adjacent is tan
tanθ = opposite/adjacent
tan(35°) = x/25
multiply both sides by 25 to isolate x
tan(35°) * 25 = x
x ≈ 17.51
