What is the total length of the tadpoles that are 1/8-inch and 1/4-inch long?
nasty-shy [4]

The dot plot shows the frequency or length of the tadpoles

The total length of the tadpoles that are 1/8-inch and 1/4-inch long is 7/8 inches

<h3>How to determine the total length?</h3>

From the dot plot, we have the following parameters:

  • 3 tadpoles have a length of 1/8
  • 2 tadpoles have a length of 1/4

So, the total length is:

Total = 3 * 1/8 + 2 * 1/4

Evaluate the product

Total = 3/8 + 1/2

Rewrite as;

Total = 3/8 + 4/8

Evaluate the sum

Total = 7/8

Hence, the total length of the tadpoles that are 1/8-inch and 1/4-inch long is 7/8 inches

PLSS HELPP BRAINLIEST AND 65 POINTS <br> pls do the graph too
Eddi Din [679]

Answer:

\Large \boxed{ -x+65}

Step-by-step explanation:

Two points are (0, 65) and (10, 55)

Calculate slope <em>m</em>

\displaystyle m=\frac{y_2 - y_1}{x_2 - x_1}

\displaystyle m=\frac{55-65}{10-0}=-1

Use slope-intercept form

y=mx+b

y=-1x+b

<em>b</em>  is the y-intercept, y-intercept is (0,65)

y=-1x+65

Cube shaped box for packing tape Cube shaped container the edge of the length of the storage container is 2 and 1/2 ft of each b
Amanda [17]

Answer:

  1/8 ft³

Step-by-step explanation:

Apparently cubic blocks that are 1/5 of 2 1/2 ft on a side are used to fill the cube that is 2 1/2 ft on a side. Then each edge of the block is ...

  (1/5) × (5/2 ft) = 1/2 ft

The volume of the block is the cube of that:

  (1/2 ft)³ = 1/8 ft³
