Mr. duc asked to set up 450 chairs in a large hall. Perry puts 20 chairs in each row. He has already set up 15 rows of chairs
Each row consists of 20 chairs
He already set up 15 rows
So number of chairs he already set up = chairs in each row * number of rows
20 * 15 = 300
So , he already set up 300 chairs
Total chairs to set up is 450
Remaining chairs to set up = 450 - 300 = 150
So, 150 more chairs to set up
Answer:
Reflections, translations, rotations, and combinations of these three transformations are "rigid transformations".
Step-by-step explanation:
The formula for area of a triangle is: 1/2 x base x height.
You are given the height of 4 and the area of 4.
Replace those in the formula and solve for x ( base)
4 = 1/2 x base x 4
Divide both sides by 4:
1 = 1/2 x base
Multiply both sides by 2:
2 = base
x = 2
Answer:
All real numbers are solutions!
Step-by-step explanation:
Let's solve your equation step-by-step.
5x+4=9+5(x−1)
Step 1: Simplify both sides of the equation.
5x+4=9+5(x−1)
5x+4=9+(5)(x)+(5)(−1)(Distribute)
5x+4=9+5x+−5
5x+4=(5x)+(9+−5)(Combine Like Terms)
5x+4=5x+4
5x+4=5x+4
Step 2: Subtract 5x from both sides.
5x+4−5x=5x+4−5x
4=4
Step 3: Subtract 4 from both sides.
4−4=4−4
0=0
Answer:
231
Step-by-step explanation:
Let's compute the probability of this event and then multiply it by 100.
As each deck has 4 suits and each suit has 3 faces, there are 12 faces in a deck.
As a deck has 52 cards, the probability of drawing a face is
<em>12/52 = 0.23076
</em>
This means that if you choose a card 1000 times from a deck of poker cards, you probably will select 231 times a face (rounding to the nearest integer).
