30% of 90 <em>whenever it says "of" put in a multiplication sign </em>
30% x 90 <em> take out the % sign (percent means divided by 100)</em>
30/100 =3/10 <em>simplify,then multiply by 90</em>
3/10 x 90 = 270/10 <em> simplify</em>
270 = 27
90 - 27 = 63 <em>subtract 27 because it is the amount read so far from the total</em>
Keisha has to read 63 more minutes to reach her goal.
Answer:
-x-6
Step-by-step explanation:
-4x - 2 + 3x - 4
Combine -4x and 3x -x - 2 - 4

You need to look at the question again, and notice the words "... did you ...".
From those words, it's clear that the question comes AFTER you have solved
several equations, and now, this question is asking you how you solved them.
The only way for YOU to answer this question is to solve the equations first.
And if you want someone ELSE to tell the math concepts and principles that
are used to solve them, then you have to show him what the equations are.
Answer:
Step-by-step explanation:
1. ¹/₃ × π × r² × l:so 33.9.29cm³
2. π × r² × l:so π x 2² x 3.5=43.98ft³
3.¹/₃ × π × r² × l, to get the radius from diameter you divide the diameter by 2 so it would look like: ¹/₃ × π x 4² x 12= 201.06in³
4.352cm³
5. cone: 1/3 πr²h
Cylinder: πr²h
cone : 33 Cylinder = 3 x 33 = 99 in³
Answer:
1,000,000
Step-by-step explanation: Since there are 10 possible digits, we know that there is a 1/10 chance for any possible digit in any slot. So, since there are 6 slots we can do 1/10^6, or 1 in 1 million.
