Grace’s catering company receives an order for 118 Apple pies. Grace used 8 Apples to make one apple pie. How many apples does she need to make all 118 pies?

Answers

Tha answer is 15 apple pies. Divide 118 pies by 8 apples. You will get 14 and a remainder. Add one more to the quotient.
She can make 14 pies total. Because if you divide 118 by 8 you get 4.75 but with the problem you are working with you can't round up so 14 would be the max number of pies you can make and you will have a few apples left over (the .75 left)

Hi there,
To get the answer to your question, we must first convert the two given equations into slope-intercept form, or y = mx + b. 
2x - 5y = -5
→y = 2/5x + 1
y = 2/5x + 1. 
Since they are the same exact equations, they are the same line, meaning they have infinitely many solutions. Therefore, the graph that best fits this system of equations is the first graph. Hope this helps and have a great day!

For a designer suit, Daniel must specify his waist size in centimeters. If there are $12$ inches in a foot and $30.5$ centimeters in a foot, then what size should Daniel specify, in centimeters, if his waist size in inches is $34$ inches? (You may use a calculator on this problem; answer to the nearest tenth.)

Answers

Divided 30.5 by 2.833 then tell me what you get should be right.

complete question:

For a designer suit, Daniel must specify his waist size in centimeters. If there are 12  inches in a foot and 30.5 centimeters in a foot, then what size should Daniel specify, in centimeters, if his waist size in inches is 34 inches? (You may use a calculator on this problem; answer to the nearest tenth.) 

Answer:

Daniel waist size in cm ≈ 86.4 cm

Step-by-step explanation:

The designer wants Daniel to express his waist size in centimetres. But his waist size was given in inches .

Let us convert the unit base on the relationship given above

12 inches = 1 foot

34 inches =  ? foot

cross multiply

34/12

2.83 ft

Therefore,

1 foot = 30.5 cm

2.83 = ? cm

cross multiply

2.83 × 30.5

86.416

Daniel waist size in cm = 86.416

Daniel waist size in cm ≈ 86.4 cm

What are Arithmetic operations?

Arithmetic operations can also be specified by the addition, subtract, divide, and multiply built-in functions.

The operator that performs the arithmetic operations are called arithmetic operators.

+ Addition operation: Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

/ Division operation: Divides left-hand operand by right-hand operand

For example 4/2 = 2

Jessica spent $36.07 and Ben spent $7.79 at the grocery store.

To determine the amount of spending Jessica and Ben together

Apply the addition operation,

⇒ 36.07 + 7.79

⇒ 43.86

43.86 can be rounded to equal 44.

Hence, Jessica and Ben spent $44 together.

What is equivalent to 4x-6y

Answers

Final answer:

The equation 4x-6y is a form of a linear equation. When re-arranged in the form y=mx+b, it simplifies to y=2/3x, where m (slope) is 2/3.

Explanation:

The equation you provided, 4x-6y, is a form of a linear equation. A linear equation can be written in the form y = mx + b, where m is the slope and b is the y-intercept. The given equation can be rewritten as y = (2/3)x - n, where n is the y-intercept that is not given in this case. The equation represents a straight line in a two-dimensional coordinate system.

To see how this conversion is done, you can isolate y in the initial equation. The initial equation is 4x - 6y = 0. If you rearrange the terms, you get -6y = -4x, and after dividing both sides by -6, you get y = (2/3)x, which is its equivalent form.

Answers

I got -4/3 or 1.333333333 as my answer.

Hope my answer is correct ☺

Answer:

The answer as a mixed fraction is  - 1 [tex]\frac{1}3}[/tex].

Step-by-step explanation:

The expression given  is,

                           (3[tex]\frac{5}{9}[/tex]) ÷ (-2[tex]\frac{2}{3}[/tex]).

Converting the two values to an improper fraction, we have:

                        [tex]\frac{32}{9}[/tex] ÷ - [tex]\frac{8}{3}[/tex]

Convert the division sign to multiplication sign, so that;

                    =  [tex]\frac{32}{9}[/tex]  × -[tex]\frac{3}{8}[/tex]

                    = - [tex]\frac{96}{72}[/tex]

Divide both the numerator and denominator by 8.

                   = - [tex]\frac{12}{9}[/tex]

                   =  - 1 [tex]\frac{1}3}[/tex]

Thus, the answer as a mixed fraction is  - 1 [tex]\frac{1}3}[/tex].

The diagram shows corresponding lengths in two similar figures find the ratio of the perimeters and the ratio of the areas

Answers

The ratio of the perimeters is the same as the ratio of the side lengths.
The ratio of the areas is the square of the ratio of the side lengths.

For example, you have two similar rectangles.
One has a side of 4 m, and the other one has a corresponding side of 12 m.
The ratio of the side lengths is 12/4 = 3.
All sides of the second one are 3 times longer than the corresponding sides of the first one. Also the perimeter of the second one is 3 tomes the perimeter of the first one.

For the areas, you must square the ratio. Since the ratio of side lengths is 3, square 3: 3^2 = 9. The area of the second one is 9 times the area of the first one.
