Answer:

x=2/3

Step-by-step explanation:

3x + 7 = 9x + 3

Collect like terms (subtract 3x from both sides and subtract 3 f4=rom both sides)

The resulting equation will look like this:

4=6x

=6x=4

Divide be 6 on both sides:

x=4/6

Simplify:

x=2/3 :-)

The population of a town increased from 3500 in 2005 to 5600 in 2009. Find the absolute and relative (percent) increase.

Ket [755]

Answer:

Absolute increase in population will be 2100

And percentage increase will be 60 %

Step-by-step explanation:

We have given population in 2005 is 3500

And population in 2009 is 5600

So absolute increase in population = 5600-3500 = 2100

We have to find the percentage increase in population

So relative percentage increase in population will be $\frac{2100}{3500}\times 100=60$ %

So population will increase by 60 %

Answer:

Following are the solution to the given question:

Step-by-step explanation:

Please find the complete question in the attached file.

$Box \ average =\frac{1}{6} \\\\SD = \frac{1}{6} \times \frac{5}{6} = \frac{5}{36} \approx 0.373\\\\Expected \ value= 1000 \times \frac{1}{6} \approx 166.7\\\\SE = 1000 \times 0.373 \approx 11.8\\\\$

The total number of aces is approximately 167, 12 or more. The SE is 12 out of 1000, which is 1.2 percent.

The percentage of aces is expected to be around 16.67% , or 1.2%.

A biology class examined some flowers in a local meadow. Out of the 40 flowers they saw, 8 were perennials. What percentage of t

Sladkaya [172]

So first we want to say, 8 out of the 40 flowers were perennials.

8 out of 40 is 8/40, or simplified down to 1/5.

1/5 in percentage form is 20% because 1 divided by 5 = 20%.

The figure shows the dimensions of a metal sign. The shaded part of the sign is painted blue.

Sonja [21]

Step-by-step explanation:

the area of a triangle is

baseline × height / 2

we have here 2 triangles : the larger, outer shaded one, and the smaller, inner white one.

to get the area of the shaded part, we need to calculate the area of the large triangle and subtract the area of the smaller triangle.

large area :

12 × 15 / 2 = 6 × 15 = 90 ft²

small area :

8 × 10 / 2 = 4 × 10 = 40 ft²

the shaded area is

90 - 40 = 50 ft²
