I just need the ratio and the explanation, Lin, Diego, and Elena are competing to see who can finish their book the fastest.

Lin read the first 54 pages from a 270-page book in the first 3 days.

Diego read the first 100 pages from a 320-page book in the first 4 days.

Elena read the first 160 pages from a 480-page book in the first 5 days.

If they continue to read every day at these rates, who will finish first, second, and third? Explain or show your reasoning:

Answers

Answer: The answer to your question is:

1st Diego

2nd Diego and Elena ( both 15 days)

Step-by-step explanation:

Data

Lin 54 pages 270-page book 3 days

Diego 100 pages 320 page 4 days

Elena 160 pages 480 page 5 days

Process

Lin

54 pages ------------------- 3 days

270 page ----------------- x

x = (270 x 3) / 54

x = 15 days

Diego

100 pages ----------------- 4 days

320 -------------------- x

x = (320 x 4) / 100

x = 12.8 days

Elena

160 pages ------------------- 5 days

480 pages -------------------- x

x = (480 x 5) / 160

x = 15 days

Step-by-step explanation: First add 23x + 4x=27x

Then subtract 54x gives you -27x

You can't add a regular number with x's so your final answer is -27x+7

A triangle has an area of 15. One of its sides has length 10. What is the length of the altitude to that side?

Answers

Answer:

Altitude = 3

Step-by-step explanation:

Given the area of a triangle as 15, with a length of 10:

We can use the following formula for finding the area of a triangle:

Area (A) = ½bh

Where:

Base (b) = 10

Height (h) or altitude = unknown

Substitute the given values into the formula:

Area (A) = ½bh

15 = ½(10)h

15 = 5h

Divide both sides by 5 to solve for h:

[tex]\displaystyle\mathsf{\frac{15}{5}\:=\:\frac{5h}{5} }[/tex]

h = 3

Therefore, the length of the altitude or height of the given triangle is 3.

- Can a whole number be 5 more than another number and
also 5 times as many as the other number? Give an example
to explain your answer.

Answers

Answer:

Nope

Step-by-step explain

1+5=6

6/5 is not 1

2+5=7

7/5 is not 2

NO, a whole number can't be 5 more than another number, & 5 times another number.

Let a whole number be = n

5 more than whole number = n + 5 ; And 5 times the whole number = 5n

Equating them , n + 5 = 5n

5n - n = 5

4n = 5

n = 5 / 4

5 / 4 is not a whole number, as it is in fractional form.

Also, 5/4 + 5 = (5 + 20) / 4 = 25 / 4

5 / 4 x 5 = 25 / 4

Both above sum & product are also in fractional form, so are not whole numbers.

Hence proven.

Answers

Answer: The correct answer is - 50.

Step-by-step explanation: :)

Answer:

Step-by-step explanation:

To calculate the mean, we do the total divided by the number of values. Therefore, to get 30, with 7 values, we need to have a total of 210. Currently, we have a total of 160, so Saturday needs to be 50, because 210-160=50.

The area of the triangle is less than 18 square inches. Select an inequality that represents a

Answers

Answer:

(1/2)(6)(a) < 18

Step-by-step explanation:

We know the formula for the area of a triangle is 1/2 b x h

The base is 6in and the height is a, so the equation is 1/2 6 x a.

The area is less than 18 sq in, so 1/2 x 6 x a < 18

Now, let's solve the inequality.

1/2 6 x a < 18

3 x a < 18

a < 6
