Answer:
18 square yards of rubber flooring
Step-by-step explanation:
We can look at the model as a 16x13 rectangle with a 6x9 rectangle cut out of it. So we can just find the area of the 16x13 rectangle and subtract the area of the 6x9 rectangle:
16*13=208
6*9=54
208-54=154
So the area of the floor is 154 square feet.
BUT the problem asks how many square YARDS of rubber flooring are required to cover the floor. Because there are 3 feet in a yard, there are 3^2 square feet in a square yard, or 9 square feet in a square yard. So we need to divide 154 by 9, which is 17 1^9. Because you can only buy 1 square yard of rubber flooring at a time, we need to buy 18 yards of rubber flooring to cover the floor.
I hope I explained this well enough. Happy mathing!
Edit: I just stood up too fast. The second picture is VERY true.
Answer:
154 ft.^2
Step-by-step explanation:
13 times 16 = 208
6 times 9 = 54
208 - 54 = 154

1# A right triangle has a hypotenuse with length 8 m and a leg of length 5.2 m.What is the length of the other leg of the right triangle? Enter the answer, rounded to the nearest hundredth, in the box.
2# A right triangle has legs of length 136 cm and 119 cm.What is the
length of the hypotenuse of the right triangle? Enter the answer, rounded to the nearest tenth, in the box.
3# The Pythagorean theorem states that a² + b² = c² for a right triangle with leg lengths, a and b, and hypotenuse length, c. The hypotenuse of a right triangle is 5 units long and has the points (3, 0) and (0, 4) as end points. One of the legs has length 3. Use the Point and Segment tools to draw a right triangle at demonstrates the other leg length is 4.

Q11 The price of a smartphone is $600 and a smart watch is $250. If you buy them together you get a discount of 20%. If you decide to buy both, how much will you end up paying?
Q12Another store is offering the smart watch for $100 if purchased with the smartphone. Is this a better deal than the previous one (Q11)?
Answer:
above is the solution to the question
Answer:
Yes, the deal for Q12 is better than the previous one.
Step-by-step explanation:
600 + 250 = 850
850 × 20 = 17000
17000 / 100 = 170
850 - 170 = 680 He will pay $680 (Q11)
Which points are reflections of each other across the y-axis?
Answer:
When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y).

Step-by-step explanation:
Sarah works at an electronic store. She earns 17% commission on everything she sells. If Sarah sold $38,000 worth of items this month, what is her commission for the month?
Answer:
$6,460
Step-by-step explanation:
I like to do it the long way, but I think it makes the most sense;
Divide 38k by 100 to get 1% of her amount (because 38k is 100%)
38000/100 = 380
Now multiply that number by 17 to get 17% because 380 is 1%, already determined above.
So thus 380*17 is 6460

i need some help with this
Answer:
it`s 5
Step-by-step explanation:
x is unknown, but it`s multiplied by 6 and by 5, so it`s 30, then space x again, which you need now to divide the opposite way. 30 / 6 = 5x
So, the answer is 5x, easy

Finding the answer for this one
Answer:
[tex]4 \frac{13}{30}[/tex] (4 13/30)
Steps :
1) Convert 1 1/6 and 3 4/5 to mixed numbers.
1 1/6 is 7/6 in mixed number and 3 4/5 is 19/5 in mixed number.
2) multiply 7/6 x 19/5, which is 7 x 19/6 x 5.
7 x 19 is 133 and 6 x 5, so it would be 133/30
3) Change 133/30 to a mixed number, which would be [tex]4\frac{13}{30}[/tex] ( 4 13/30)
To get the answer, you need to do 133/30, which is 4.43333, witch would be 4 13/30 ([tex]4\frac{13}{30}[/tex])

Which ratio best defines experimental probability?
Number of times an event occurs: Total number of times the activity is performed
Total number of times the activity is performed: Number of times an event occurs
Number of nonfavorable outcomes: Number of possible outcomes
Number of possible outcomes: Number of nonfavorable outcomes
Answer:
Number of times an event occurs : Total number of times the activity is performed
Step-by-step explanation:
Experimental probability is the probability of an event occurring based on actual experimental results, whereas theoretical probability is the expected probability of an event occurring.
For example, the theoretical probability of flipping a coin and it landing on a head is 1/2.
If we carried out an actual experiment where we flipped the coin 20 times, recorded the results, and only 5 of the flipped coins landed on heads, then the experimental probability of the coin landing on a head would be 5/20 = 1/4.
The more trials we carry out, the closer the experimental probability gets to the theoretical probability.
Therefore, the best definition of experimental probability is:
Number of times an event occurs : Total number of times the activity is performed
Answer:
Answer:Number of times an event occurs : Total number of times the activity is performedStep-by-step explanation:Experimental probability is the probability of an event occurring based on actual experimental results, whereas theoretical probability is the expected probability of an event occurring.For example, the theoretical probability of flipping a coin and it landing on a head is 1/2. If we carried out an actual experiment where we flipped the coin 20 times, recorded the results, and only 5 of the flipped coins landed on heads, then the experimental probability of the coin landing on a head would be 5/20 = 1/4.The more trials we carry out, the closer the experimental probability gets to the theoretical probability.Therefore, the best definition of experimental probability is:Number of times an event occurs : Total number of times the activity is performed
Step-by-step explanation:
A cell phone provider offers a plan that costs $40 per month plus $0.10 per text message sent or received. A comparable plan costs $60 per month but offers unlimited text messaging. If you send or receive an average of 50 text messages each month, which plan would you choose? Why?
Okay so $40 a month, 10 cents per message.
10 cents times 50 messages is only 5 dollars.
So, it would be around $45 a month.
If I only sent around that many messages a month, I would just go with the $40 a month, cause you can save around $15.

Which function has a y-value of 12, if the x-value is 3?
y = 4 x
y = x - 6
y = x + 8
y = 3 x
Replace x with 3 and solve for y to equal 12:
y = 4(3) = 12
the answer is y = 4x
Answer:4x
Step-by-step explanation:
i will give brainliest to good answer PLEASE HELP ME!!!!!! i'm so confused screenshot and instructions attached
Answer:
When 0< x < 5, |x - 5| = 5 - x and |x+5| = x + 5. Summed, we get y = 10
When -5< x < 0, |x - 5| = x - 5 and |x+5| = 5 - x. Summed, we get y = 10.
Combined, y = 10.

Answer:29
so the mini triangle in the corner is a mini model of the entire triangle, all you have to do is take the width or bottom number and find the factor in which it is smaller, then take the height of the smaller triangle and add the factor in which it increases to it. so the factor goes up by 31 1/2--9=22 1/2 and adding the factor in which it increases to the height is 22 1/2+6 1/2=29 because 2 halfs make a whole.
