Step-by-step explanation:
Jared and Alyssa made a stack of hay bales. Each bale has a volume of 1 m3. They made 3 layers with 6 bales in each layer. A) What is the volume of the stack? _______ b) How many rows of bales could be in each layer? _______ c) How many bales could be in each row? _______
Answer:
1) 18 m^3
2) 2 rows per layer.
3) 3 bales per row.
Step-by-step explanation:
Volume of bale = 1 m^3
Layer has 3 layers tall ams 6 layers.
Total volume = 1 x 3 x 6 = 18 m^3
The most stable arrangement will be to have 2 rows of 3 bales per layer.
There could be 3 bales per row

Step-by-step explanation:
Rory was with some friends outside an ice cream parlor. He noticed that one out of every four people bought a vanilla cone. He wants to know the estimated probability that five randomly picked people entering the shop will not buy vanilla cones. How could you design a simulation of the scenario?
Answer:
"Spin the spinner 5 times with 4 equal segments. One of the segment represents vanilla on either the spinner as well as three parts reflect certain flavors" would be the right answer.
Step-by-step explanation:
The actual probability of the given scenario will be:
⇒ [tex](1-\frac{1}{4})^5[/tex]
⇒ [tex](1-0.25)^5[/tex]
⇒ [tex](0.75)^5[/tex]
On solving the power, we get
⇒ [tex](0.237304)[/tex]
Now on multiplying the above value in 100, we get
⇒ [tex]23.73[/tex]%
Approximately 23.73% chance vanilla was not chosen by either of the five. So that the above is the right answer.
Answer:
Spin a spinner with four equal sections five times. On the spinner, one section represents vanilla and three sections represent other flavors.
Which constant could each equation be multiplied by to eliminate the x variable in this system of equations?
4x + 5y = 62
5x – 3y = 22
Step-by-step explanation:
4x + 5y = 62 | ×5 |
5x – 3y = 22 | ×4 |
20x + 25y = 310
20x – 12y = 88
_____________--
37y = 222
y = 222/37
y = 6
4x + 5y = 62 | ×3 |
5x – 3y = 22 | ×5 |
12x + 15y = 186
25x – 15y = 110
_____________+
37x = 296
x = 296/37
x = 8

Answer:17.32
Step-by-step explanation:
AB =
Round your answer to the nearest hundredth.
B
5
2
40
Answer:
AB = 6.53
Step-by-step explanation:
cos theta = adjacent/ hypotenuse
cos 40 = 5/ AB
AB cos 40 = 5
AB = 5/ cos 40
AB = 6.527036447
Round to the nearest hundredth
AB = 6.53

Answer:
3/8
Step-by-step explanation:
Find the height of the trapezoids
20 - 10 = 10
10/2 = 5
Find the area of the trapezoids
5*(20+10)/2 = 75
The formula for the area of the trapezoid is the height * the bases added together divided by 2
75*2(this is because there are 2 trapezoids) = 150
Put this to proportion of the total area of the dart board
150/[tex]20^{2}[/tex] = 150/400 = 3/8
3/8 is the probability that you score 3 points
What is the range of the following set?
27, 18, 29, 25, 23, 23, 21, 32, 20
Answer:
The range is 14.
Step-by-step explanation:
To find the range in a data set, you have to subtract the lowest number from the highest number in the set. The highest number is this set was 32. The lowest was 18. 32-18=14. Thus, the answer is 14.
You can drive 900 miles in 20 hours. At this rate, how long would it take to drive 135 miles?
Answer:
It would take 3 hours to travel 135 miles.
Step-by-step explanation:
[tex]\frac{900}{135} =\frac{20}{x}[/tex]
So, if you cross multiply 135 by 20 that equals 2,700
Next, 2,700 divided by 900= 3
It would take 3 hours to travel 135 miles.
Write an Algebraic Expression for Problems 1 - 6.
1. Five less than eight times a number
2. Thirteen more than a number
3. A number divided by seven
4. John went to Cinemark. The movie cost $12 and each drink cost $3.50. How much did he
spend after buying d number of drinks?
5. At the bowling alley, Stacey bowled x number of games and rented a pair of shoes. How
much did she spend at the bowling alley?
6. The volleyball team spent $675.95 at the mall. If each player spent the same amount, how
much did each player spend?
Answer:
I'm gonna rewrite each sentence in a way that lines up a little more with the Algebraic expression you would end up with. Just keep in mind that either way of saying it is correct.
1. "8 times some number (a variable) minus 5"
8x-5
2. "13 plus some number"
13+x
3. "Some number over 7"
x/7 or x÷7
4. "d number of drinks times 3.50 plus 12 equals how much John spent (we'll call it J)"
12+3.50d = J
5. "Stacey bowled x number of games times the cost of one game (call it B) plus the cost of the shoes (call it P) which equals how much they spent (call it S)"
xB+P = S
6. "675.95 dollars was spent at the mall by a number of players (call it P) to equal the total cost per player)"
$675.95÷p (players) = 675.95/p (dollars/player)
Essentially you're making expressions or equations out of numbers you know and putting in variables as place holders for numbers you don't know. The variables can be whatever letters you like, but you'll want to write what each variable represents down nearby. Otherwise the reader/your teacher won't know what's what.
How do u find the unknown angle measure in a triangle
Answer:
Use the sum of angle measures rule.
Step-by-step explanation:
If you are given two angles and one missing angle, it's good to remember that all angles add up to 180°.
You can add the the given angles measurements, and subtract them by 180. You should then get the missing angle measure.

Which triangle is both scalene and acute?
Answer:
i think its the first one
Step-by-step explanation:
What is the measurement of < SRT
Triangle
R unknow
S 53 degree
T 48 degree
A) 69 °
B) 79°
C) 99°
D)101 °
Answer:
The sum of all the angles of any triangle is 180°
So, 180 - (53 + 48) = 180 - 101 = 79
<SRT = 79°

The graph of f(x)= x is translated 3 units down to form the graph of g(x). Which of the following is g(x)
Answers :
A: g(x)= -3x
B: g(x)= 3x
C: g(x)= x - 3
D: g(x)= x + 3
Answer:
I'll edit the answer and try to answer it, but where is the graph?
Answer:
C: g(x)= x- 3
Step-by-step explanation:
translated 3 units down means you go 3 down on the y-axis. Therefore it is g(x)= x-3
can someone tell me how to do this
Answer:
must not be
Step-by-step explanation:
The whole thing equals 360 degrees
Angle B and Angle D are equal; which equals 190 degrees.
Add Angle A to 190 degrees; which is 86 + 190 = 276.
Subtract 360, which is what the whole thing equals, and 276, which is the known angle added together, and you get 56.
In order for this to be a parallelogram, the opposite angles need to be equal.
Since they are not, the answer is must not be.

brainly which is the distance between (-3,4) and (7,13)
Answer:
Root 181
Step-by-step explanation:
Using distance formula, we know that the answer will be the square root of 181. Unfortunately, this is not a perfect square, and it is prime, so that number will remain the same.
Distance Formula: [tex]\sqrt{(13-4)^{2} + (7+3})^2} = \sqrt{181}[/tex]

Using sigma notation write the geographic series: 6+12+24+48+96
Answer:
[tex] $$\sum_{n=1}^{5} 6(2^{n-1}) $$ [/tex]
Step-by-step explanation:
6 + 12 + 24 + 48 + 96 =
= 6 + 6 * 2 + 6 * 4 + 6 * 8 + 6 * 16
= 6 + 6 * 2^2 + 6 * 2^2 + 6 * 2^3 + 6 * 2 * 4
= 6 * 2^(n - 1)
[tex] $$\sum_{n=1}^{5} 6(2^{n-1}) $$ [/tex]
