A single batch of cookies requires two cups of sugar and three cups of flour. If more than one batch or a partial batch was made, the unit rate of sugar to flour would remain the same.

Match the correct amount of sugar to the correct amount of flour to keep the same unit rate of sugar and flour in a single batch.

11.25 cups of flour
8 cups of sugar
7.5 cups of flour
11.5 cups of flour

What is the equation of the line that passes through the point (5, -2) and has a slope of 6/5

Answers

Answer:  y = (6/5)x-8

Slope = 6/5 = 1.2

Y intercept = -8

==================================================

Work Shown:

m = 6/5 = 1.2 is the given slope

(x,y) = (5,-2) is the point the line goes through

y = mx+b .... slope intercept form

y = 1.2x + b .... plug in the given slope

-2 = 1.2*5 + b ... plug in the coordinates of the given point

-2 = 6 + b

-2-6 = 6+b-6 .... subtracting 6 from both sides

-8 = b

b = -8

The equation y = mx+b turns into y = 1.2x-8

This is equivalent to y = (6/5)x-8

Describe the transformation from the parent function to the function g(x)=2 times 3^x-4

Answers

Answer:

Step-by-step explanation:

The parent function of g(x) = 2*3^x-4 would be 3^x

The transformation would include: shifting parent function 4 units down (-4) and compressing the function (2)

The movement (shifting) of the graph is caused by the y-intercept. If the y-intercept is positive, the graph moves up and vice versa.

The coefficient which is multiplied determines whether the function is compressed (squeezed) or stretched. If the coefficient is less than 1, then the function is stretched. If the coefficient is greater than 1, then the function is compressed.

Find the 76th term of the arithmetic sequences 16 14 12

Answers

Answer:

a₇₆ = - 134

Step-by-step explanation:

The n th term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 16 and d = a₂ - a₁ = 14 - 16 = - 2, then

a₇₆ = 16 + (75 × - 2) = 16 - 150 = - 134

3 1/6 cups of flour.

Step-by-step explanation

Answer: 3 1/6 cups

Step-by-step explanation:

The question is asking to find the sum of both types of flour. 1 1/2 cups of the first flour was used and 1 2/3 cups of the second was used. In order to combine these fractions, they must first have a common denominator. the fractions can be made into 1 3/6 and 1 4/6 in order to do this. Next, add the fractions to get 2 7/6 cups of flour. Finally, simplify the previous fraction to get the final answer of 3 1/6 cups.

Set up an algebraic inequality, solve, and write a sentence answering the question. Jasmine has a goal to workout a total of at least 6 hours this week. Her workout sessions are always 3/4 an hour long. She already worked out for 1 1/2 hours. What is the minimum number of workout sessions she would need to complete in order to achieve her weekly goal?

Answers

Answer:

6 work out sessions

Step-by-step explanation:

From the above question, we know that:

Jasmine has a goal to workout a total of at least 6 hours this week.

Her workout sessions are always 3/4 an hour long.

Hence: Her total workout sessions

3/4 hour = 1 workout session

6 hours = x

Cross Multiply

3/4 × x = 6 × 1

x = 6/3/4

x = 6 ÷ 3/4

x = 6 × 4/3

x = 8 work out sessions

We are told that:

She already worked out for 1 1/2 hours.

Hence: if :

3/4 hour = 1 workout session

1 1/2 hours = x

Cross Multiply

3/4 × x = 1 1/2

x = 1 1/2 ÷ 3/4

x = 3/2 ÷ 3/4

x = 3/2 × 4/3

x = 2 work out sessions

Therefore:

the minimum number of workout sessions she would need to complete in order to achieve her weekly goal is calculated as:

8 work out sessions - 2 work out sessions

= 6 work out sessions

Converting this to workout sessions

a television is reduced in price from £800 to £600, what is the percentage production

Answers

Answer:

The percentage decrease = 25%

Step-by-step explanation:

Given

Starting value = £800Final value = £600

To determine

Percentage decrease

Using the percentage decrease formula

% decrease = [Starting Value - Final Value] / [Starting Value] × 100

                    = [800 - 600] / [800] × 100

                    = [200] /  [800] × 100

                    = 0.25 × 100

                    = 25%

Therefore, the percentage decrease = 25%
