Answer:

Knowing that 3²+4²=5, draw the 3cm side and 4cm side with right angle between them. The 5cm side will fit to form a right triangle.

Option D is correct option.

Step-by-step explanation:

We are given sides: 2cm, 3cm, 4cm and 5cm. We need to choose the correct option according to converse of the Pythagorean Theorem

The converse of the Pythagorean Theorem is:

<em>If the square of the length of the longest side of a triangle is equal to the sum of the squares of the other two sides, then the triangle is a right triangle.</em>

Now, if we sum the square of 2 smaller sides, it should be equal to square of longest side.

So, if add:

(3)^2+(4)^2=(5)^2

We get: 9+16=25

25=25

So, the sides of triangle are 3cm, 4cm and 5 cm.

Now, the longest side will be hypotenuse so, 5cm is hypotenuse, 3 cm and 4cm can be base and perpendicular.

And the angle will of 90 degrees will be between base and perpendicular.

So, the correct option is:

Knowing that 3²+4²=5, draw the 3cm side and 4cm side with right angle between them. The 5cm side will fit to form a right triangle.

Option D is correct option.

The formula for the size of a file that was downloaded over time t and at an average rate r is r.t.
lakkis [162]

Answer:

The size of file downloaded is  <em>88 megabytes.</em>

Step-by-step explanation:

Given that:

Average rate of downloading the file = r

Time taken to download = t

Formula for the size of file downloaded = r.t

Rate of downloading, r = 800\ kilobytes/sec

Time taken, t = 110 seconds

To find:

Size of file downloaded in megabytes = ?

Solution:

First of all, let us apply the given formula to find the size of file downloaded:

Size of file downloaded = r.t

Size of file downloaded = 800 kilobytes seconds \times 110 seconds =

<em>88000 kilobytes</em>.

Now, let us convert the unit kilobytes to megabytes to find the answer.

<em>Conversion formula:</em>

1000 kilobytes = 1 megabyte

Let us use unitary method to find the number of megabytes in 88000 kilobytes.

1 kilobytes = \frac{1}{1000} megabytes

88000 kilobytes = \frac{1}{1000} \times 88000 megabytes

\Rightarrow <em>88 megabytes.</em>

Therefore, the size of file downloaded is  <em>88 megabytes.</em>

25 POINTS Trina's Toy Company charges $0.85 per pound to ship toys.
d1i1m1o1n [39]

Answer:

Part A

C = $.85p

For 2 pounds , the charge is $1.70

Part B

C = $.05 * p

Step-by-step explanation:

Part A

Cost = charge per pound * pounds

We know the charge per pound is $.85

C = $.85 * p

We want to ship 2 pounds

C = .85*2

C = 1.70

Part B

Cost = charge per pound * pounds

We know the charge per pound is now $.05

C = $.05 * p
