What are the side lengths of a rectangle if the area = 40 in and the perimeter = 48 in

Answers

Answer 1

Answer: 4, 10, 4, 10. 10*4 gives area of 40. 10+10+4+4 gives 48 as shown in question

Answer 2

Answer: $a,b-the\ side\ lengths\ of\ a\ rectangle\n \na\cdot b=40\ [in^2]\ \ \wedge\ \ \ 2\cdot(a+b)=48\ [in]\n \n a+b=24\ \ \ \Rightarrow\ \ \ a=24-b\ \ \ \Rightarrow\ \ \ ab=(24-b)b=24b-b^2\n \nab=40\ \ \ \Rightarrow\ \ \ 24b-b^2=40\ \ \ \Rightarrow\ \ \ -b^2+24b-40=0\ /\cdot(-1)\n \nb^2-24b+40=0\ \ \Rightarrow\ \Delta=(-24)^2-4\cdot40=576-160=416=16\cdot 26\n \n$

$√(\Delta) =4 √(26) \ \ \ \Rightarrow\ \ \ b_1= (24-4 √(26) )/(2)=12-2 √(26)\ \Rightarrow\ a_1=12+2 √(26) \n \n.\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ b_2= (24+4 √(26) )/(2)=12+2 √(26)\ \Rightarrow\ a_2=12-2 √(26)$

The number of chips of different colors in Gail's bag is shown below:3 blue chips
4 pink chips
8 white chips
Gail takes out a chip from the bag randomly without looking. She replaces the chip and then takes out another chip from the bag. What is the probability that Gail takes out a white chip in both draws?
A. $(8)/(15)$ + $(7)/(14)$ = $(217)/(210)$
B. $(8)/(15)$ × $(7)/(14)$ = $(56)/(210)$
C. $(8)/(15)$ + $(8)/(15)$ = $(16)/(15)$
D. $(8)/(15)$ × $(8)/(15)$ = $(64)/(225)$

Answers

Answer:

$(8)/(15) * (8)/(15)=(64)/(225)$

Step-by-step explanation:

Given : 3 blue chips

4 pink chips

8 white chips

To Find: What is the probability that Gail takes out a white chip in both draws with replacement?

Solution:

Blue chips =3

Pink chips =4

White chips =8

Total chips = 3+4+8 =15

Now Probability of getting white chip on first draw = $\frac{\text{Number of white chips }}{\text{Total no. of chips}}$

= $(8)/(15)$

Now ,She replaces the chip and then takes out another chip from the bag.

So, Probability of getting white chip on second draw = $(8)/(15)$

Probability of getting white chip in both draws = $(8)/(15) * (8)/(15)=(64)/(225)$

Hence the probability that Gail takes out a white chip in both draws is $(8)/(15) * (8)/(15)=(64)/(225)$

Thus Option D is correct.

most likely the probability is D because my mom said it is d i dont know how she got it

How many times can 7 go into 48

Answers

To find out the answer to this question, we can do it one way by subtracting 7 from 48 until we can't subtract 7 anymore without getting a negative number.

48 - 7 = 41

41 - 7 = 34

34 - 7 = 27

27 - 7 = 20

20 - 7 = 13

13 - 7 = 6

Now, we can just count the 7s that we subtracted, and when we do, we can see that there are 6 of them, and then we are left with 6, and since 7 can't be subtracted from 6, that will be our remainder.
7 goes into 48 6 times with a remainder of 6.
Hope that helped! =)

Name a pair of fractions that use the least common denominator and are equivalent to 9/10 and 5/6

Answers

The fractions that use the least common denominator and are equivalent to 9/10 and 5/6 are 27/30 and 25/30 respectively

Given:

9/10

5/6

find the least common multiple of the denominators 10 and 6

10 = 10, 20, 30, 40, 50

6 = 6, 12, 18, 24, 30, 36, 42

The least common multiple is 30

find an equivalent fraction that has 30 as the denominator using x as numerator

9/10 = x/30

9 × 30 = 10 × x

270 = 10x

x = 270/10

x = 27

5/6 = x/30

5 × 30 = 6 × x

150 = 6x

x = 150/6

x = 25

Therefore, the pair of fractions that use the least common denominator and are equivalent to 9/10 and 5/6 are 27/30 and 25/30 respectively

brainly.com/question/10600831

The Lowest Common Denominator is 30
9/10 = 27/30
5/6 = 25/30
