How do I find the perimeter of a rectangle that has 9m and 3m

1 answer:

7 0

With the given numbers, you can already assume what the other two lengths are. The shorter length of 3m will typically be the length of the shorter side or the height while 9m will typically be the width.

With this information, you have all your sides now - both of the shorter sides are 3 and the longer sides are 9.

To find perimeter, you now add all of the sides together which results in 24m being you're perimeter.

Hope this helps!

A jar contains 3 red, 2 white, and 1 green marble. Aside from color, the marbles are indistinguishable. Two marbles are drawn at

IRISSAK [1]

Answer:

0.6

Step-by-step explanation:

A permutation is an arrangement of outcomes whereas a combination is a grouping of outcomes.

Order matters in case of permutations but does not matter in combinations.

Given:

Number of red marbles = 3

Number of white marbles = 2

Number of green marbles = 1

To find: probability of picking 4 marbles and getting one of each color

Solution:

Total number of outcomes = $6_C__4$ = $\frac{6!}{4!\,2!}=\frac{6\times 5\times 4!}{4!\times 2}=15$

Number of favourable outcomes = 2 red, 1 white and 1 green marble + 1 red, 2 white and 1 green marble = $3_C_2\,2_C_1\,1_C_1+3_C_1\,2_C_2\,1_C_1$ = $\frac{3!}{2!\,1!}\times \frac{2!}{1!\,1!}\times 1+\frac{3!}{2!\,1!}\times 1\times 1=6+3=9$

So, probability of picking 4 marbles and getting one of each color = Number of favourable outcomes/Total number of outcomes = $\frac{9}{15}=\frac{3}{5}=0.6$

Find the inverse of the function y = x2 - 12.

Semmy [17]

Good evening ,

Answer:

The inverse of the function y = x² - 12 is

x = √(y + 12)

Step-by-step explanation:

for y ≥ -12 :

x² - 12 = y ⇔ x² = y + 12 ⇔ x = √(y + 12).

Adam is going to cook a turkey for 14 people and wants to allow ¾ lb of turkey for each person.

ArbitrLikvidat [17]

I did (450*3/4=337.5) to get how much each person would eat, then I did (337.5*14=4725g) to see how big the turkey should be. I then converted grams to kilos (4725*0.001=4.725 kg), and I got how big the turkey would be. It turns out the appropriate size of the turkey would be medium, so then what I did was that I looked for the medium price of the turkey per kg, and found that it was £5.99 per kg. I did (4.725*5.99) and I got about £28.30. It would cost £28.30 for 14 people.
