Find the volume of the rectangular prism.
Write your answer in simplest form.
3/5m
4/9m
2/5 m

Answers

Answer:

8/75

Step-by-step explanation:

To find the volume of a rectangular prism you multiply the length, width, and height.

So you do (3/5)*(4/9)*(2/5), and to multiply fractions you multiply the tops by eachother, and then the bottoms by eachother.

So its (3*4*2) over (5*9*5)

which gives you 24/225 which simplifies to 8/75

Pablo grew a plant for school and recorded the growth of the plant
each week. He wrote ordered pairs to organize his data: (1, 5), (2, 8),
(3, 8), (4, 11), (5, 15).
Is this relation a function? Explain.

Answers

Answer:

Yes. the relation is a function

Step-by-step explanation:

Here, we want to check if the relation is a function

if a relation is a function, then every x-values (input values) will have one y-value

No two output values (y values) will have a single x value

Looking at the pairs;

It is a function

Although two x values have same y value; 2 and 3 to 8; no two y values have same x value

Hence, the ordered pairs is a function

Tim has read ​30 % of a book. He has 56 more pages to finish. How many pages are there in the​ book?

Answers

Answer:

80 pages

Step-by-step explanation:

Let the number of pages is xTim has read ​30 % of a book

Remaining

100% - 30% = 70%

70% of x is 0.7x

0.7x = 56x = 56/0.7x = 80 pages

Answer:

[tex] \bf \huge 80 \: pages[/tex]

Step-by-step explanation:

Given that :

Tim has read 30 % of a book.He has 56 more pages to finish.

to find :

How many pages are there in the book ?

let us assume :

total pages of book is 100•/•

explanation :

⟼ total book = 100•/•

⟼ Tim has read 30 % of a book.

⟼ 100 - 30 •/• = 70 •/•

⟼ 70 •/• = 56 pages

⟼ 1 •/• = 56 / 70

⟼ 100 •/• = 56 / 70 × 100

⟼ 100 •/• = 56 / 7 × 10

⟼ 100 •/• = 8 × 10

⟼ 100 •/• = 80 pages

∴ tim has 80 total pages in book.

area of a regular hexagon with an apothem of 15 cm

Answers

Answer:

area = 779.4 cm²

Step-by-step explanation:

divide it into 6 equal equilateral triangles. Each corner of a triangle will be 60°.

tan 60° = 15/x

1.7321 = 15/x

x = 8.66 (this is one-half of the base of the triangle)

base = 17.32 cm

area of one triangle = 1/2(17.32)(15) = 129.9 cm²

129.9(6) = 779.4 cm²   (because 6 triangles make up the hexagon)

Find the intercepts of the linear function: -3 = 3y – 3.2

Answers

Answer:

The given line is a horizontal one, with slope 0 and y-intercept (0, -2/3)

Step-by-step explanation:

To find the y-intercept, set x = 0 (which is the y-axis) and find y:

-3 = 3y - 3.2

Add 3.2 to both sides, to isolate 3y:

0.2 = 3y

Dividing both sides by 3 yields   y = 0.06667

The given line is a horizontal one, with slope 0 and y-intercept (0, -2/3)

Answer:

The perimeter of the triangle is 34 cm

Step-by-step explanation:

Here, we want to find the perimeter of the triangle

This is simply the sum of the side lengths

mathematically, the distance of two lines from a point touching the circle is the same

so, on the other sides, we have the missing sides as;

5cm, 4 cm and 8 cm

So the perimeter will be;

4cm + 5cm + 8 cm + 4 cm + 8 cm + 5 cm = 34 cm
