Answer:
72 Wrong, so find how many are right with 135 total
Step-by-step explanation:
It's similar to saying if she answered half and this continued how many would she have answered after answering a bigger number, you would say half.
so she answered 8/15 incorrectly a a smaller number, so she will answer that ratio with a bigger number. If it helps 8/15 is about 53%. just like 1/2 is half. So to find half you would multiply something by 1/2 and int he same way you multiply something by 8/15 to get that proportion of it.
so 135, if you take this 53%, or simply multiply it by 8/15 you get your answer of 72. So 72 wrong so al others are right, which you get with 135-72 = 63.
You could also do 135*(1-8/15) = 135 * 7/15. if you ever want to find something NOT part of the proportion you do 1 - that proportion.
Answer:
it's 3.
Step-by-step explanation:
10-4/5-3
6/2
3..
70 cups>35 pints>17.5 quarts of water in a week
10 cups × 7 days (a week)= 70 cups
2 cups = 1 pints
70 cups ÷ 2= 35 pints
2 pints = 1 quart
35 pints ÷2 = 17.5 quarts
Hope this helps!
When reading questions like these, watch out for "or", which means to add.
There are a total of 15 tiles;
There are 5/15 (1/3 simplified) A tiles.
There are 3/15 (1/5 simplified) E tiles.
There are 1/15 Z tiles.
There are 2/15 M tiles.
There are 3/15 (1/5 simplified) L tiles.
There is 1/15 Y tiles.
We are looking for E or Y, which means we must add their fractions together.
E = 3/15, Y = 1/15.
3/15 + 1/15 = 4/15
You have a 4/15 chance of drawing an E or a Y.
I hope this helps! :)
Using the equation of best fit provided:
y=0.216x + 32.575
The slope is the number with the x, so the slope is 0.216 and the y- intercept is the number added at the end. The y intercept is 32.575
