• 1(1.69 ounce) package candy-coated milk chocolate pieces (such as M&M's(R))
• 1 (1.5 ounce) box raisins
Your answer

Answers

Answer:

12.65 = 12 65/100

         = 12 13/20

10.5 = 10 5/10

       = 10 1/2

3.2 = 3 2/10

     = 3 1/5

1.69 = 1 69/100

1.5  = 1  5/10

     = 1  1/2

Step-by-step explanation:

The weight of salted peanuts is expressed in fraction as [tex]12 \frac{13}{20}[/tex] ounce.

Given that, salted peanuts = 12.65 ounce.

How to convert decimals to fractions?

Decimals can be written in fraction form. To convert a decimal to a fraction, place the decimal number over its place value.

Now, salted peanuts = 12.65 ounce in fraction is

12.65 = [tex]12 \frac{65}{100}[/tex]

= [tex]12 \frac{13}{20}[/tex] ounce

10.5 ounce package miniature marshmallows

In fraction 10.5 = [tex]10 \frac{5}{10}[/tex]

= [tex]10 \frac{1}{2}[/tex] ounce

3.2 ounce package sunflower seeds

In fraction 3.2 = [tex]3 \frac{2}{10}[/tex]

= [tex]3 \frac{1}{5}[/tex] ounce

1.69 ounce package candy-coated milk chocolate pieces

In fraction [tex]1 \frac{69}{100}[/tex]

1.5 ounce box raisins

In fraction [tex]1 \frac{5}{10}[/tex]

= [tex]1 \frac{1}{2}[/tex]

Therefore, the weight of salted peanuts is expressed in fraction as [tex]12 \frac{13}{20}[/tex] ounce.

Work out the percentage change to 2 decimal places when a price of £60 is increased to £89.99.

Answers

Answer:

49.98%

Step-by-step explanation:

Original price: £60

New price: £89.99

The difference in prices: £89.99 - £60 = £29.99

£60 - 100% (the original price)

£29.99 - x  (the % that we want to calculate)

29.99 × 100 = 2999

Answer: The correct answer is y=15(100)−5

Step-by-step explanation:

The equation is written as y = 100 - 5x. Then the amount of money left after 5 months will be $25.

What is a linear equation?

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

Beth acquires $100 from her grandma. She intends to pay her grandma $15 every month until the cash is taken care of.

Let 'x' be the number of months and 'y' be the remaining amount. Then we have

y = 100 - 15x

The amount of money left after 5 months is calculated as,

y = 100 - 15 (5)

y = 100 - 75

y = $25

The condition is composed of y = 100 - 5x. Then how much cash left following 5 months will be $25.

one of the angles of a regular octagon has a measure of (7x-5) What is the value of x?

Answers

Answer:

  x = 20

Step-by-step explanation:

The interior angles of a regular octagon have measures of ...

  180° -360°/8 = 135°

We want that equal to the given expression.

  7x -5 = 135

  7x = 140 . . . . add 5

  x = 20 . . . . . divide by 7

The value of x is 20.

Answer:

20

Step-by-step explanation:

Regular octagon means that each angle is 135 degrees, so 135 = (7x - 5).

135 = 7x - 5,

135 + 5 = 7x,

140 = 7x,

140 / 7 = x,

Answers

The answer is: 7/7

hope this helps :))

The angle of slope of the line between the coordinates (-4, 10) and (-8, -6) is 4.

What is the Linear equation?

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.

To find the slope of a line, we use the formula:

slope = (change in y) / (change in x)

We can use the given points (-4, 10) and (-8, -6) to find the slope:

change in y = (-6) - 10 = -16

change in x = (-8) - (-4) = -4

slope = (-16) / 4 = 4

Therefore, the slope of the line passing through the points (-4, 10) and (-8, -6) is 4.
