Which fraction is greater than 1/2 and less than 3/4 ?

Answers

Answer:

a. [tex] \frac{2}{3} [/tex]

Step-by-step explanation:

The fraction, [tex] \frac{2}{3} [/tex] is greater than [tex] \frac{1}{2} [/tex] and less than [tex] \frac{3}{4} [/tex].

How do we know this? See below how the fractions are compared together.

First, compare [tex] \frac{2}{3} [/tex] and [tex] \frac{1}{2} [/tex].

Find a common denominator for both fractions:

Common denominator of 2 and 3 would be 6. Therefore, multiply as follows:

[tex] \frac{2 \times 2}{3 \times 2} = \frac{4}{6}[/tex] and

[tex] \frac{1 \times 3}{2 \times 3} = \frac{3}{6} [/tex].

Compare the numerators. Which one is greater?

Form the calculation above:

[tex] \frac{2}{3} = \frac{4}{6} [/tex] has a numerator of 4.

.

[tex] \frac{1}{2} = \frac{3}{6} [/tex] has a numerator of 3.

Since 4 is greater than 3, therefore, the fraction, [tex] \frac{2}{3} [/tex] is greater than [tex] \frac{1}{2} [/tex].

✍️Compare [tex] \frac{2}{3} [/tex] and [tex] \frac{3}{4} [/tex].

Find a common denominator for both fractions

[tex] \frac{2 \times 4}{3 \times 4} = \frac{8}{12} [/tex] and

[tex] \frac{3 \times 3}{4 \times 3} = \frac{9}{12} [/tex]

Comparing their numerator, 8 is less than 9, therefore:

[tex] \frac{2}{3} [/tex] is less than [tex] \frac{3}{4} [/tex].

✔️We can conclude that:

[tex] \frac{2}{3} [/tex] is greater than [tex] \frac{1}{2} [/tex], and less than [tex] \frac{3}{4} [/tex].

a rectangular prism has a width of 0.5 a height of 4 and a length of 1.5, what is the surface area of the rectangular prism?

Answers

Answer:

The surface area of the rectangular prism is 17.5

Step-by-step explanation:

We are given:

Width of rectangular prism (w) = 0.5

Length of rectangular prism (l) = 1.5

Height of rectangular prism (h) = 4

We need to find the surface area of the rectangular prism.

The formula used is: [tex]Surface \ area \ of \ the \ rectangular \ prism=2(lw+lh+wh)[/tex]

Putting values and finding the surface area of the rectangular prism

[tex]Surface \ area \ of \ the \ rectangular \ prism=2(lw+lh+wh)\\Surface \ area \ of \ the \ rectangular \ prism=2((1.5)(0.5)+(1.5)(4)+(0.5)(4))\\Surface \ area \ of \ the \ rectangular \ prism=2(0.75+6+2)\\Surface \ area \ of \ the \ rectangular \ prism=2(8.75)\\Surface \ area \ of \ the \ rectangular \ prism=17.5[/tex]

So, the surface area of the rectangular prism is 17.5

Bouncing Baby Company sells their cribs for the following amounts to stores
Number of Cnbs
10
Price
$1320
50
S6600
Which of the following statements about the price of the cribs are true if the price remains proportional to the number of cribs Select TWO that apply.
A. 6 cribs cost $600

B. 22 anos cost $2640

C. 40 cribs cost $5280

D. 55 cribs cost $7920
E. 80 cribs cost $10.500
F. 250 cribs cost $11 880

Answers

Answer:

Option C

Step-by-step explanation:

Since, Price of cribs (P) are proportional to the proportional to the number of cribs (N) sold,

P ∝ N

P = kN

Here 'k' is the proportionality constant

To get the value of proportionality constant,

Since, value of 10 cribs is $1320

1320 = k(10)

k = 132

Therefore, equation will be

P = 132N

Option A

If number of cribs = 6

P = 132(6) = $792

False.

Option B

For N = 22

P = 132(22) = $2904

False.

Option C

For N = 40

P = 132(40) = $5280

True

Option D

For N = 55

P = 132(55) = $7260

False

Option E

For N = 80

P = 132(80)

  = $10560

False

Option F

For N = 250

P = 132(250)

  = $33000

False

The cost of mailing a first-class letter is $0.46 for the first ounce and $0.20 for each additional ounce or portion of an ounce. Y is the total cost for mailing a letter that weighs x ounces. What is the cost of mailing a first class letter weighing 2.5 ounces based on the guidelines given in the previous problem?

Answers

Answer:linear function

Step-by-step explanation:

The cost of mailing a first class letter weighing 2.5 ounces is $0.96,

What are linear equation?

A linear equation only has one or two variables. No variables in a linear equation is raised to power greater than 1 or used as denominator of a fraction.

Now given that,

cost of mailing a first-class letter for the first ounce = $0.46

cost of additional ounce or portion of an ounce = $0.20

Since,the weight of letter is x ounces

cost of mailing a first-class letter = $0.2x

Now,Y is the total cost for mailing a letter

Y = 0.46 + 0.2x

Therefore, the cost of mailing a first class letter weighing 2.5 ounces

Y = 0.46 + 0.2*2.5

⇒ Y = 0.46 + 0.5

Y = $0.96

Thus,The cost of mailing a first class letter weighing 2.5 ounces is $0.96

A recipe calls for 2/3 cups of sugar per batch. Elena used 5 1/3 cups of sugar to make multiple batches of cookies. How many batches did she make?

Answers

Answer:

8

Step-by-step explanation:

In order you find the answer, you must divide 5 1/3 by 2/3.

In order to do this, you have to convert 5 1/3 into an irregular fraction, by multiplying 5 by 3 and adding it to 1. You'll end up with 16/3

When dividing fractions, you multiply the first number by the reciprocal of the second. 16/3 is the number being divided, so 2/3 will be our second number. The reciprocal of 2/3 is 3/2.

16/3 x 3/2 = 8.

What was the value of b?
A. –6
B. –2
C. 2
D. 10

Answers

Answer: C. 2

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

Begin by removing the brackets

4x + 5(-4x - b) = -16x - 5b

-(x - 2) = -x + 2

Add the two binomials together to get the third one

4x -20x - 5b - x + 2 = -17x - 8                 Combine the like terms on both sides

-17x - 5b +2 = -17x - 8                             Add 17x to both sides

-5b + 2 = - 8                                           Subtract 2 from both sides

-5b +2 -2 =- 8 -2                                     Combine    

-5b =  - 10                                               Divide by -5

b = -10/-5

b = 2
