Given : the perimeter of the right angle triangle is 96cm the length in sides are in a ratio 6:8:10. work out the area of the triangle in cm²

Need to Find : The area of the Rectangle

_____________________________________

Let us assume the constant multiple be x

So,

Let the length be 10x

Let the breadth be 6x

Let the height be 8x

Now, as we know that the Perimeter of rectangle is 96 cm

★ Perimeter = Sum of all three sides of a triangle

➛ 96 cm = 6x + 8x + 10x

➛ 96 cm = 24x

➛ x = 96/24

➛ x = 4 cm

Putting x = 4 we get

Length = 10(4) = 40 cm

Breadth = 6(4) = 24 cm

Height = 10(4) = 32 cm

As we know that

★ Area = ½ × Base × Height

➛ Area = ½ × 24 × 32

➛ Area = 12 × 32

➛ Area = 384 cm²

Henceforth the area is 384 cm²

Answer:

384 cm^2

Step-by-step explanation:

The perimeter is calculated by adding all side lengths

if the ratio is 6:8:10 then let x represent the numbers

then we can make this equation

6x + 8x + 10x = 96

24x = 96 divide both sides by 24

x = 4 the side lengths are 6*4, 8*4 and 10*4

The area of a triangle is calculated by multiplying height and base and that divided by two

in right triangles the height is the larger leg and the base is the shorter leg

so the area of this triangle is :

32*24 / 2 = 384 cm^2

Jasmine fills her bathtub, takes a bath, and then drains the tub. Which graph best depicts this situation by relating time to wa

S_A_V [24]

Answer:

Step-by-step explanation

It would be thw third option bc she fills up the tub with water = Increas level of water

Than she bathes in it= Constant

and than she drains her bath tub= Decreases

So it would be the third option that states

A graph has time on the x-axis and water level on the y-axis. The water level increases, is constant, and then decreases.

A heap of rubbish in the shape of a cube is being compacted into a smaller cube. Given that the volume decreases at a rate of 3

inna [77]

Answer:

-1/4 meter per minute

Step-by-step explanation:

Since, the volume of a cube,

$V=r^3$

Where, r is the edge of the cube,

Differentiating with respect to t ( time )

$\frac{dV}{dt}=3r^2\frac{dr}{dt}$

Given, $\frac{dV}{dt}=-3\text{ cubic meters per minute}$

Also, V = 8 ⇒ r = ∛8 = 2,

By substituting the values,

$-3=3(2)^2 \frac{dr}{dt}$

$-3=12\frac{dr}{dt}$

$\implies \frac{dr}{dt}=-\frac{3}{12}=-\frac{1}{4}$

Hence, the rate of change of an edge is -1/4 meter per minute.

A half-gallon carton of organic

kotegsom [21]

Answer:

The price of milk in 5 years = $7.16

Step-by-step explanation:

Given:

Present cost of half-gallon carton milk = $4.45

Increase percentage = 10%

To find the price of milk in 5 years.

Solution:

To find the price of milk in 5 years we will apply the exponential growth formula which is given as:

$F_v=P_v(1+r)^t$

where

$F_v\rightarrow$ final value

$P_v\rightarrow$ present value

$r\rightarrow$ rate of increase in decimals

$t\rightarrow$ time in years.

From the given data, we can plugin values in the equation to calculate final value in dollars after 5 years.

$F_v=4.45(1+0.1)^5$

$F_v=4.45(1.1)^5$

$F_v=4.45(1.61)$

$F_v=7.16$

Thus, price of milk in 5 years = $7.16

Help I am confused this does not come back to me when ever I look in my book.

KIM [24]

We know that point M is a midpoint of segment RS, and line l passes through segment RS. Since l passes through RS at its midpoint, M, then we can declare that l is the bisector of RS. Your best answer is A since the above is the basic definition of a bisector.
