i didnt know how to do b
Step-by-step explanation:
it is bcz 99÷16 is 6
Answer:
(a) 3 rows had 16 chairs.
(b) 3 rows had 17 chairs.
Explanation:
There must be 6 rows, which is constant.
Make equation's:
1st equation: 16p + 17w = 99
2nd equation: w + p = 6, w = 6 - p
Solve by substitution:
⇒ 16p + 17(6 - p) = 99
⇒ 16p + 102 - 17p = 99
⇒ -p = -3
⇒ p = 3
Then find w, w = 6 - p = 6 - 3 = 3
Hence, there is 3 rows of 16 chairs and 3 rows of 17 chairs.
Try to match match and confirm the answer:
17 × 3 + 16 × 3 = 99 chairs in 6 rows9. Three dice are tossed. Find the probability of the specified event.

The following figures are similar. Find the value of x.
PLEASE HELP I CURRENTLY HAVE AN F BUT I WONT ANYMORE IF YOU HELP ME
(If you can help me with my Graphing Coordinations question please do!)
Answer:
x = 10
Step-by-step explanation:
Both obects are similar right. That means that they must have similar angles, similar sizes and similar scale factors.
For me by just looking at the figires I can conclude a similar scale factor which is 1.7. However we are going to calculate the scale factor.
First we must take notice that the triangle D'E'F' is an enlargement. So to find the scale factor we must the same sides of both triangle and divide the larger sid by the smaller side.
68 ÷ 40 = 1.7
Now that we have the scale factor (1.7) we can now find x.
The similer side D'F' = 17 and DF = x.
We are gonna use the scale factor to divide D'F' to find DF.
17 ÷ 1.7 = 10
Therefore x is 10
-(-9)_l-9l is it grater than or less than or eqaul to?
Answer:
Equal to
Step-by-step explanation:
Hello!
Let's simplify the left side:
- ( -9 ) 9Remember that the negative sign also means opposite, so the opposite of negative 9 is positive 9.
Let's simplfy the right side:
| - 9 |9Remember that in an absolute value bracket, any positive value stays positive, but any negative value turns to the positive value.
So the inequality is 9 _ 9
Therefore the sign should be "=" as 9 is equal to 9.

19. In a "TriboNcci" sequence, each number after the third number is the sum of the preceding three numbers. For example, if the first three numbers are 5,6, and 7 , then the fourth number is 18 because 5 + 6 + 7 = 18, and the fifth number is 31 because 6 + 7 + 18 = 31. The first five numbers of another TriboNcci sequence are P, Q, 86, 158, and 291 in that order. What is the value of P ?
Answer: each number after the third number is the sum of the preceding three numbers. For example, if the first three numbers are 5, 6, and 7, then the fourth number is 18 because 5 + 6 + 7 = 18 and the fifth number is 31 because 6 + 7 + 18 = 31.

Heres another brainly question giving 20pts!!
Answer:
We are given an area and three different widths and we need to determine the corresponding length and perimeter.
The first width that is provided is 4 yards and to get an area of 100 we need to multiply it by 25 yards. This would mean that our length is 25 yards and our perimeter would be 2(l + w) which is 2(25 + 4) = 58 yards.
The second width that is given is 5 yards and in order to get an area of 100 yards we need to multiply by 20 yards. This would mean that our length is 20 yards and our perimeter would be 2(l + w) which is 2(20 + 5) = 50 yards.
The final width that is given is 10 yards and in order to get an area of 100 yards we need to multiply by 10. This would mean that our length is 10 yards and our perimeter would be 2(l + w) which is 2(10 + 10) = 40 yards.
Therefore the field that would require the least amount of fencing (the smallest perimeter) is option C, field #3.

Answer:
(-5,7)- Quadrant 2
(8 1/2,-4)- Quadrant 4
(0,5)-y axis
Step-by-step explanation:
Step 1: Determine where the point lies
(-5, 7) has a negative x value which means that it's either in the second or third quadrant. Now looking at the y value and it being positive we know that we are in the second quadrant.
(8.5, -4) has a positive x value which means that it's either in the first or fourth quadrant. Now looking at the y value and it being negative we know that we are in the fourth quadrant.
(0, 5) has a x value of 0 which means that our point lies on the y-axis.
A train travels at an average speed of 80 km/h. How long will it take the train to travel 320 km?
Answer:
4 hours
Step-by-step explanation:
If the train travels at ~80 kilometers per hour, you just divide the total distance (in this case, 320 kilometers) by the speed traveled (80 kilometers). 320/80 = 4 hours.
Susan is buying 5 and a half pies from the market. Write this amount as a mixed number, improper fraction, decimal and percent.

Find the surface area of a rectangular prism that has the dimensions shown.
length: 4.5 in.
width: 6 in.
height: 12 in.
S
A
=
in
2
Answer:
S(A) = 306 in²
Step-by-step explanation:
The surface area of a rectangular prism can be found using the following equation:
SA(rectangular prism) = 2(wl + hl + hw)
Note:
w = width = 6
h = height = 12
l = length = 4.5
Plug in the corresponding numbers to the corresponding variables:
SA(rectangular prism) = 2((6 * 4.5) + (12 * 4.5) + (12 * 6))
SA(rectangular prism) = 2((27) + (54) + (72))
SA(rectangular prism) = 2(27 + 54 + 72)
SA(rectangular prism) = 2(153)
SA(rectangular prism = 306
S(A) = 306 in²

(08.05 MC) The box plot below shows the number of years that 12 schools have participated in an interschool swimming meet: A box and whisker plot is drawn using a number line from 0 to 10 with primary markings and labels at 0, 5, 10. In between two primary markings are 4 secondary markings. The box extends from 1 to 6 on the number line. There is a vertical line at 3.5. The whiskers end at 0 and 8. Above the plot is written Duration of Participation. Below the plot is written Years. At least how many schools have participated for more than 1 year and less than 3.5 years? (1 point) 3 6 10 11
Answer:
20% of the total schools participated for 6 years or more. This is because the part of the box plot wherein it hits 6 years and above is 20%. Thus, if there are 20 schools, then 20% of it would be 4. In conclusion, there are 4 schools that participated for 6 years or more.

Turn the equation into a simpler form
[tex]s = \sqrt{\frac{SS}{n-1} }[/tex]
[tex]s = \sqrt{\frac{64}{5-1} }[/tex]
[tex]s = \sqrt{\frac{64}{4} }[/tex]
[tex]s = \sqrt{16}[/tex]
That said, we know the square root of 16 is 4, so 4 would be your answer.
