Cost of five lemons is $2.
What is the cost per lemon?
Answer: $
per lemon
Part B
At this rate, what is the cost of 9 lemons?

Answers

Answer:

Part a: $0.40 per lemon, Part b: $3.60

Step-by-step explanation:

Because the cost of five lemons is $2, it would be: 5 lemon = $2

$2/5 lemons = $x/1 lemon

so divide by 5 on the numerator and denominator. 2 divided by 5 = 0.4

So part a: 40 cents or $0.40 per lemon!

Part B:

cost of 1 lemon compared to 9 lemons:

$0.40/1 = x/9

Multiply both numerator and denominator by 9

So, it costs $3.60 for 9 lemons.

The rule:

y = x + 3

y = 0 + 3

y = 3

y = 3 + 3

y = 6

y = 11 + 3

y = 14

y = 7 + 3

y = 10

y = 9 + 3

y = 12

Therefore, the missing number on the table is 14

b) Sea Grass is the furthest below the Surface of water.

What is Ascending Order?

Numbers can be arranged in ascending order, from least value to highest value. The arrangement is left to right. Increasing order is another name for ascending order.

Given:

-20 3/4, -15 1/2, -14 3/4, -1/4

Now, Writing the above fraction into Normal fraction

-83/4, -31/2, -67/4, -1/4.

Now, Arranging the data in ascending Order

-83/4 < -67/4 < -62/4 < -1/4.

A construction worker drops a hammer while building the Grand Canyon skywalk 4,000ft above the Colorado River. Use the formula t=h−−√4 to find how many seconds it takes for the hammer to reach the river. Round your answer to the nearest tenth of a second.

Answers

Answer:

15.8

Step-by-step explanation:

We are asked to find how many seconds it takes for an object to fall from a height of 4,000ft. We will use the given formula, t=h−−√4. Substituting h=4,000, we find

t=4000−−−−√4=15.8

So, the hammer reaches the river after 15.8 seconds.

a. Explain in words what is done to the input value (20) to produce the output value (y).
b. Write the rule you described in part (a) with algebraic symbols.

Answers

Answer:

(a) Rule: Multiply the input (x) by 2 and add 5 to the result of the product

(b) [tex]y =2x +5[/tex]

Step-by-step explanation:

Given

The attached table

Solving (a): The rule of the table in words

First, we calculate the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Using:

[tex](x_1,y_1) = (2,9)[/tex]

[tex](x_1,y_1) = (10,25)[/tex]

So, we have:

[tex]m = \frac{25 - 9}{10 - 2}[/tex]

[tex]m = \frac{16}{8}[/tex]

[tex]m=2[/tex]

The equation is calculated using:

[tex]y - y_1 =m(x - x_1)[/tex]

Using:

[tex](x_1,y_1) = (6,17)[/tex]

We have:

[tex]y - 17 =2(x - 6)[/tex]

[tex]y - 17 =2x - 12[/tex]

Make y the subject

[tex]y =2x - 12+17[/tex]

[tex]y =2x +5[/tex]

Hence, the rule is:

Multiply the input (x) by 2 and add 5 to the result of the product

(b): The rule, in algebra

As solved in (a), the rule is:

[tex]y =2x +5[/tex]
