Answer:

490,000

Step-by-step explanation:

since 9 is the number we are rounding we look at the next number to the right and either we round up or down depending upon that number. since it is a 3 we round down but if it was a 5 or higher that number would be 500,000

Answer: 490,000 or 493,300 depending on the nine you are rounding.

Step-by-step explanation:

if the number before the 9 is 5 or more, you round up, if its 4 or less you round down .

A fish tank in a pet store has 23 fish in it. 10 are orange and 13 are white. Determine the probability that if we select 4 fish

Gala2k [10]

Answer:

ok so the probility of gettting one white fish is

13/23

and if we take out one white fish the problity is

12/22

so we just multiply

12/22*13/23=0.30830039525

so the problity is 0.30 if you choose two fish you will get white for both

Tony used a photocopier to dilate the design for a monorail track system. The figure below shows the design and its photocopy

Darina [25.2K]

Answer:

12 m

Step-by-step explanation:

Given that the design, ABCD, was dilated to get a photocopy, EFGH, a scale factor or ratio was multiplied by the original lengths of the design to get the new measurement of the photocopy.

Thus, we are given the ratio, CD:GH = 2:3.

This means, any of the corresponding lengths of both figures would be in that same ratio.

Using the ratio of the design to the photocopy, 2:3, we can find the length of side EH of the photocopy.

The corresponding side of EH in the design is AD = 8m. Thus, AD to EH = ⅔

$\frac{AD}{EH} = \frac{2}{3}$

$\frac{8}{EH} = \frac{2}{3}$

Cross multiply

$3*8 = 2*EH$

$24 = 2*EH$

Divide both sides by 2 to make EH the subject of formula

$\frac{24}{2} = \frac{2*EH}{2}$

$12 = EH$

The length of side EH = 12 m

Answer:

2 hours 40 minutes

Step-by-step explanation:

If you add 3 hours, it will be 7:45

You subtract 20 minutes to get to 7:25

3 hours - 20 minutes = 2 hours 40 minutes

Find the ratio of the area of triangle XBY to the area of triangle ABC for the given measurements, if BY = 3, YC = 2

Mazyrski [523]

Answer:

The ratio of the area of triangle XBY to the area of triangle ABC is $\frac{9}{25}$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is equal to the scale factor and the ratio of its areas is equal to the scale factor squared

In this problem

Triangles XBY and ABC are similar, because the corresponding internal angles are congruent

see the attached figure to better understand the problem

step 1

Find the scale factor

Let

z-------> the scale factor

$z=\frac{BY}{BC}$
