Answer:
x = 26
Step-by-step explanation:
The angles x and 64 are complementary since they equal 90 degrees
They equal 90 degrees since the make a straight line with a right angle
x+64 = 90
Subtract 64 from each side
x+64-64 = 90-64
x = 26
What you must do for this case is to extract the relationship of the grapes that were eaten yesterday among the grapes that were eaten today.
To do it, let:
x: number of grapes that Reza ate yesterday
(x / 20) = (100/400).
Clearing x we have:
x = (100/400) * (20) = 5
answer
the number of grapes Reza ate yesterday was 5
Answer:
26

13+13=26
Answer:
if:
- The cards are drawn without replacement,
- All cards in this set are distinct from one another, and
- The ordering of the four chosen cards does not matter.
Step-by-step explanation:
.
Assume for now that the ordering of the four cards does matter. Hands like and would then be considered different from one another.
There would choices for the first card. Since the first card was not returned to the pile, there would be only choices for the second card. Likewise, there would be choices for the third card and for the fourth.
By this reasoning, there would be different ways to draw a hand of four cards from this set when the ordering of these four cards do matter.
However, in many card games, once a hand of cards is drawn, the ordering of cards within that hand does not matter. In other words, hands like and would not be considered as distinct from one another.
In that case, the ways of drawing cards would include a large number of duplicates.
There are be ways to arrange a hand of four cards when the order matter. Hence, when the ordering within a hand no longer matters, each hand of four cards would have been counted times among those ways.
Therefore, when the ordering of cards within a set does not matter, would give the number of distinct ways to draw a hand of four out of this set of thirty distinct cards.
The Answer for #1 is found as follows:
Perimeter is the sum of all sides so...
8x+2+5x-4+9x+3=?
Group together the x's and the numbers:
8x+5x+9x+2-4+3=?
<u>Answer = 22x+1</u>
The Answer for #2 is found as follows:
Area of a triangle is 1/2 base times height
The bottom of the triangle is 4t, but we know t is 4 inches, so the bottom is 16.
The height is 7 times t which is 4... so the height is 28 inches.
using the formula, it will be 1/2(16)(28). <u>The answer will be 224 inches squared.</u>
The Answer for #2 is found as follows:
Polynomials cannot have squares or fractions. <u>So the 2nd, 3rd, and 4th options are all not polynomials. </u>
