A ball rolled from Point A to Point B in 18 second at a speed of 14 m/s. IT took another 18 seconds to roll form Pint B to Pint C at a speed of m/s. Find the total distance the ball rolled.
Answer:
d=252m, u dint put the speed it was rolling at from point B to C so I could only solve for A to B. However if you use the formula below you can find the distance from B to C and add that to A to B giving the total distance rolled.
Step-by-step explanation:
d=vt
v=14m/s
t=18s
d= vt, (14m/s)(18s)
d=252m

What is the volume of the figure composed of two congruent triangular prisms if a = 4 units, b = 2 units, and c = 6 units?
Write your answer as cubic units, e.g. 20 cubic units
The volume of the figure composed of two congruent triangular prisms is 48 cubic unit.
What is Volume?The area that any three-dimensional solid occupies is known as its volume. These solids can take the form of a cube, cuboid, cone, cylinder, or sphere.
Cubic units are used to quantify a solid's volume. For instance, the volume will be given in cubic metres if the dimensions are given in metres.
We have, a= 4 unit, b= 2 unit and c= 6 units
So, the Volume of Triangular prism
= 1/2 x b x h x l
= 1/2 x 4 x 2 x 6
= 4 x 6
= 24 cubic unit
Thus, the required volume is
= 24 x 2
= 48 cubic unit

Ok soo for the first one we're gonna use sine, (remember SOH CAH TOA) since we know the value of the hypotenuse.
Sin37° = x/9.3
0.6018=x/9.3
x= 5.59674
The last one we'll use cosine because we know the value of the side adjacent to 96°.
Cos42°=5.1/y
0.7431=5.1/y
y= 6.86272692
I assume it has you round your answers to the nearest tenth so the first one would be 5.6 and the second would be 6.9 .

Help question is in the pic PLEASE EXPLAIN HOW YOU GOT THE ANSWER!
Part A
The rectangular prism is a box, and the volume of the box is
V = L*W*H
so we simply multiply the length (L), width (W) and height (H)
In this case, the dimensions of the box are
L = 13W = 5H = 6The order doesn't matter in this case because we can multiply two or more numbers in any order we want (eg: 6*7 = 7*6 = 42)
So,
V = L*W*H
V = 13*5*6
V = 390
The volume of one box is 390 cubic inches.
I'm not sure what formula Diego is using. It seems like he's computing the perimeter of the base (the 13 inch by 5 inch rectangle) to get 13+5+13+5 = 36 inches. Then he's multiplying that by 6 to get 36*6 = 216; however, this value is meaningless because we won't involve the perimeter at all when it comes to finding the volume.
--------------
So in short, Diego is incorrect. All Diego needs to do is multiply the three values 13, 5 and 6 to get the volume of one box to be 390 cubic inches.
====================================================
Part B
Use the same formula back in part A. That formula being V = L*W*H.
We'll use this formula to compute the volume of each carton.
Carton A has a volume of 10*13*28 = 3640 cubic inchesCarton B has a volume of 10*14*22 = 3080 cubic inchesCarton C has a volume of 11*12*26 = 3432 cubic inchesAll three cartons have a volume larger than 390 cubic inches, meaning that we can fit at least one box.
If one box is 390 cubic inches, then 8 of them lead to a volume of 8*390 = 3120 cubic inches. Note that this value (3120) is larger than the volume of carton B. There's no way that Diego can use carton B to hold all 8 boxes at once. So we have no choice but to rule it out.
Carton C on the other hand has a volume of 3432 cubic inches, which is larger than the 3120 figure we got. Meaning he can house all 8 boxes here. The amount of leftover space is 3432-3120 = 312 cubic inches which is what the packing material will take care of. In other words, you need 313 cubic inches of packing material for carton C. Carton A is a similar story, but will require more packing material (since carton A's volume is larger).
The best option is to go with carton C. It allows him to hold all the 8 boxes, with the least amount of packing material required.
Kim surveyed the students at her school to find out if they like hotdogs and/or burgers. The table below shows the results of the survey:

Total
Like Burgers
32
49
81
Do Not Like Burgers
44
25
69
Total
76
74
150
If a student likes hotdogs, what is the probability that student also likes burgers?
93.8%
50.7%
42.1%
39.5%
Answer:
like burgers with the wrong total of 76/150 is 50.7%
do not like burgers with also the wrong total of 74/150 is 50% simplified
now with the right totals its 54% for liking burgers and 46% for not liking
Step-by-step explanation: 32 + 49 + 81 = 162
44 + 25 + 69 = 138
right total (162) wrong total (76)
right total (138) wrong total (74)
right (300) wrong (150)
unless u simplified by 2 which is 150/300 then its right simplified
so im confused but this is my answer
Answer:
Years late but I'll answer anyway. It is C. 42.1%
Step-by-step explanation:
A two-way table is a bivariate table. Bivariate tables have rows and columns just as your table has.
Remember, a column is vertical and a row is horizontal. Each value in the data table is called a cell.
In this case, you have to do column relative frequency. This is a cell frequency divided by the column total. It's not as hard as it may sound.
The number of people who like hotdogs and burgers is 32, and the total for that column is 76. All you have to do is divide 32 by 76 and you have your answer.
32 / 76 = 0.421 or 42.1%

In a right triangle, apart from the right angle, the other two angles are
x + 1 and 2x + 5. find the angles of the triangle.
Answer:
The two other angles are 29 degrees and 61 degrees
Step-by-step explanation:
There are 180 degrees in a triangle. Given this is a right triangle one of the angles is 90 degrees. As in the other two angles have to equal up to 90 degrees. Now we have to find x.
180 - 90 = 90
If x equals 28
28 + 1 = 29
2 x 28 + 5 = 61
29 + 61 = 90
The two other angles are 29 degrees and 61 degrees
Answer:
29 , 61
Step-by-step explanation:
Sum of all angles of a triangle = 180
90 + x + 1 +2x +5 = 180 {Combine like terms}
96 + 3x = 180 {Subtract 96 from both sides}
3x = 180 - 96
3x = 84 {Divide both sides by 3}
x = 84/3
x = 28
x +1 = 28 +1 = 29
2x +5 = 2*28 + 5 = 56 + 5 = 61
