Choose the two expressions that are equivalent to 5. 75 ÷ 1. 15
A: 575 ÷115
B: 5,750 ÷ 1,150
C: 5,750 ÷ 115
D: 575 ÷ 1,150​

Answers

Answer:

A and B, but I’m gonna explain it the best I can too.

Step-by-step explanation:

5.75 divided by 1.15 is the same as answer A, since all you are doing is taking away the periods, making it whole numbers.

Again 5.75 divided by 1.15 is the same as B as well, Since it is the same just without the periods and an added zero at the end of each.

This Is so that they are both all equivalent by being whole numbers, but whatever you do to one numbers in the expression that you think is the answer you have to do to the other numbers in the expression

they have to add up completely the same.

Use the law of cosines:

cos F = (e² + g² - f²)/2egcos F = (2.6² + 8.3²- 7.2²)/2(2.6)(8.3)          = 0.5516∠F = arccos 0.5516∠F = 57° (rounded to the nearest degree)

Answer:

57

Step-by-step explanation:

cos F = (e² + g² - f²)/2eg

cos F = (2.6² + 8.3²- 7.2²)/2(2.6)(8.3)

∠F = arccos 0.5516

∠F = 57° (rounded to the nearest degree)

Sandra bought 4 pounds of sweet potatoes for $6.28. What is the cost per pound of the sweet potatoes?

Answers

Answer:

Cost of 1 sweet potato is $6.28 divided by 4 which will give $1.75

Answer:

$1.57

Step-by-step explanation:

What we know:

- There are 4 pounds of sweet potatoes

- 4 pounds of sweet potatoes cost $6.28

To find the cost per pound of sweet potatoes, divide $6.28 by 4.

6.28 ÷ 4

= $1.57

Therefore, the cost per pound of sweet potatoes is $1.57.

Guys please help ahhhhhh math homework isnt the best haha

Answers

I'm not sure if this is exactly right because the wording of the problem is confusing.

Answer:

a) Number of square feet of wallpaper for bedroom = 12x^2 - 21

b) Number of square feet of wallpaper for living room = 14x^2 - 42

c) Total amount of wallpaper needed = 26x^2 - 63

d) 107 more sq ft of wallpaper will be needed for the living room than bedroom.

Step-by-step explanation:

a) First find the area of each wall.

Length: 3x, Width: 3x, Height: x

(3x × x) + (3x × x) + (3x × x) + (3x × x) = 3x^2 + 3x^2 + 3x^2 + 3x^2 = 12x^2

12x^2 represents the amount of wallpaper needed, including the door. Find the area of the door and subtract it from this value.

3 × 7 = 21

12x^2 - 21 = Total sq ft of wallpaper needed for bedroom

b) First find the area of each wall.

Length: 4x, Width: 3x, Height: x

(4x × x) + (4x × x) + (3x × x) + (3x × x) = 4x^2 + 4x^2 + 3x^2 + 3x^2 = 14x^2

14x^2 represents the amount of wallpaper needed, including the door. Find the area of both doors and subtract it from this value.

3 × 7 = 21 × 2 = 42

42x^2 - 42 = Total sq ft of wallpaper needed for living room

c) Add the two expressions to find the total amount of wallpaper needed.

(12x^2 - 21) + (42x^2 - 42) = 26x^2 - 63

26x^2 - 63 = Total sq ft of wallpaper needed for both rooms

d) Plug x = 8 into the equations found in part a and b.

12(8)^2 - 21 = 747

14(8)^2 - 42 = 854

Subtract these answers to find the difference in amount.

854 - 747 = 107

The living room needs 107 sq ft more of wallpaper than the bedroom

Convert the decimal to a fraction in simplest form:
0.333

O 533/1000

1
O 333 —

1
O 3 —
333


O 333/1000

Answers

Answer:

Decimal 0.333 to a fraction in simplest form is:   [tex]\frac{333}{1000}[/tex]

Step-by-step explanation:

Given the decimal

[tex]0.333[/tex]

Multiply and divide by 10 for every number after the decimal point.

There are three digits to the right of the decimal point, therefore multiply and divide by 1000.

Thus,

[tex]0.333=\frac{0.333\cdot \:\:1000}{1000}[/tex]

         [tex]=\frac{333}{1000}[/tex]         ∵ 0.333×1000 = 333

Let us check if we can reduce the fraction [tex]\frac{333}{1000}[/tex]

For this, we need to find a common factor of 333 and 1000 in order to cancel it out.

But, first, we need to find the Greatest Common Divisor (GCD) of 333, 1000

Greatest Common Divisor (GCD) :

The GCD of a, b is the largest positive number that divides both a and b without a remainder.

Prime Factorization of 333:      3 · 3 · 37

Prime Factorization of 1000:      2 · 2 · 2 · 5 · 5 · 5

As there is no common factor for 333 and 1000, therefore, the GCD is 1.

Important Tip:

As GCD is 1, therefore the fraction can not be simplified.

Therefore, decimal 0.333 to a fraction in simplest form is:   [tex]\frac{333}{1000}[/tex]
