Write the length and height of the small box. Show your working
LENGTH of small box: .......cm
HEIGHT of small box: ......cm
Answers
Answer:
length = 20 cm
height = 15 cm
Step-by-step explanation:
Large Toy Box
length = 120 cmheight = 90 cmGiven:
Each length of the small toy box is one sixth of the corresponding lengths of the large toy box.Therefore, to calculate the length and height of the small toy box, multiply the length and height of the large toy box by one sixth:
[tex]\sf length=120 \times \dfrac16=\dfrac{120 \times 1}{6}=\dfrac{120}{6}=20 \ cm[/tex]
[tex]\sf height=90 \times \dfrac16=\dfrac{90 \times 1}{6}=\dfrac{90}{6}=15 \ cm[/tex]
Therefore,
length = 20 cmheight = 15 cmAnswer:
length = 20 cm , height = 15 cm
Step-by-step explanation:
calculate [tex]\frac{1}{6}[/tex] of the dimensions by dividing the large box dimensions by 6
length of small box = 120 cm ÷ 6 = 20 cm
height of small box = 90 ÷ 6 = 15 cm

In the game of Pick-A-Ball, there are 10 colored balls: 2 red, 4 white, and 4 blue. The balls have been placed into a small bucket, and the bucket has been shaken thoroughly. You will be asked to reach into the bucket without looking and select 2 balls. Because the bucket has been shaken thoroughly, you can assume that each individual ball is selected at random with equal likelihood of being chosen. It is common in games of chance to be rewarded for obtaining unlikely results. For example, in the game of poker, hands that are less likely to occur tend to trump hands that are more likely to occur. That same concept applies in this game. It costs $10 to play Pick-A-Ball, and your prize is the reciprocal of the probability of obtaining your exact sequence of results, expressed in dollars. For example, if the probability of obtaining your exact sequence of results is 0.10, your prize is 1/0.10

What is the probability of selecting the color of ball that you just selected?
Answers
Answer:
The probability of selecting the color of ball that you just selected(a red ball) is [tex]P(r) = \frac{2}{10}[/tex]
Step-by-step explanation:
From the question we are told that
The total number of colored balls is n = 10
The number of red balls is r = 2 red
The number of white ball is w = 4
The number of blue balls is b = 4
The number of balls to be selected is N = 2 balls
The cost of playing picking a ball is c = $10
The winnings is [tex]k = \$ P(A)[/tex]
Here P(A) is the probability of obtaining the exact sequence of result and from the question it is P(A) = 0.10
Generally my price according to the question is
[tex]k = \frac{0.10 }{10}[/tex]
=> [tex]k = 0.01 [/tex]
Let assume we selected a red ball
Generally the probability of selecting a red ball is mathematically represented as
[tex]P(r) = \frac{2}{10}[/tex]

Step-by-step explanation:
=> 7780.05 = 28.25 x 13.5 x h
multiply h by 13.5
=> 7780.05 = 28.25 x 13.5h
make h the subject of formula
=> 13.5h × 28.25 = 7780.05
Let's solve your equation step-by-step.
=> 13.5h(28.25)=7780.05

The volume of two spheres are in the ratio 27:125. What is the ratio of their areas?
Answers
The volume of two spheres are in the ratio 27:125. The ratio of their areas is 9:25
If the volume of two spheres are in the ratio 27:125, then the ratio of their areas is 9:25.
How to compute the above ratioThe ratio of the volumes of two spheres is equal to the ratio of the cubes of their radii.
Therefore, if the volume ratio is 27:125, the radius ratio would be the cube root of that, which is 3:5.
The surface area of a sphere is given by the formula A = 4πr², where A is the surface area and r is the radius.
Since the radius ratio is 3:5, the ratio of their surface areas would be (3/5)² : 1², which simplifies to 9:25.
Therefore, the ratio of the surface areas of the two spheres is 9:25.

Use a net to find the surface area of the right triangular prism shown:
(I’ll give you 50 points)
Answers
The surface area of the right triangular prism is 270 sq ft
Total surface ara of the prismThe total surface area of the prism is the sum of all the area of its faces
For the two triangles
A = 2(0.5bh)
A = bh
A = 7 * 12 = 84 sq.ft
For the two rectangles
A = 2lw
A = 2(6*12)
A = 2 * 72 = 144 sq.ft
For the third triangle;
Area 6ft * 7ft
Area = 42 sq.feet
