Johnny bought an oil painting originally priced at $80 but on sale for 50% off. After 10% sales tax, what was the total cost?
Answer:
Step-by-step explanation:
A sales tax is never applied until money actually changes hands.
So you need to start by taking 50% off.
50% 0f 80 dollars = 50/100 * 80 = 4000/100 = 40
So the cost of the painting = 80 - 40 = 40
Now apply the sales tax
10% of 40 dollars = 10/100 * 40 = 400/100 = 4
The total cost = 40 + 4 = 44 dollars

Terry walks 1/4 mile each morning
and 2/4 mile each afternoon. How far does Terry walk in 3 days? Draw bar diagrams and write equations to solve
the problem
Answer:
1 1/2
Step-by-step explanation:
To solve this problem, we need to find how many miles Terry walks in one day. Then, we can multiply by 3 to find how far she walks in three days.
One day |
We need to add how much she walks in both the morning and afternoon. 1/4 + 2/4 = 3/4 miles.
Three days |
Now that we know how much Terry walks in one day, we need to find how much she walks in three days. Multiple by 3 to solve this.
3/4 * 3 = 6/4 = 3/2
You can write 3/2 as an improper fraction: 1 1/2.

Step-by-step explanation:
as the first 2 lines show us : there is a linear relationship between minutes and words.
1 minute correlates to 250 words.
2 minutes correlate to 500 = 2×250 words.
so, we see, every minute represents 250 words.
therefore, 3 minutes (A) correlate to 3×250 = 750 words.
and 5 minutes (B) correlate to 5×250 = 1250 words.

Why is 45 minutes
equal to 3/4 of an hour?
1 hour = 60 minutes
45 min = (45 min)/(60 min) = 45/60 = 3/4 of an hour.
To go from 45/60 to 3/4, I divided both top and bottom by the GCF 15.
Answer:
45 minutes equal to 3/4 of an hour because, if you convert the one hour into minutes (60 minutes) it is divisible by 15 four times.
3 · 15 = 45.

What is a circle?A circle is a geometrical figure which becomes by plotting a point around a fixed point by keeping a constant distance.
In another meaning, a circle is a geometrical figure whose shape is just like round wheel.
In our daily life, we always see circle objects for example our bike wheel.
Area of circle = πr² and the perimeter of circle = 2πr where r is the radius of the circle.
