Hello, I am papaguy Your answer is ready!

Answer: A rational number is any number that can be expressed as a whole number, a fraction, or as a non repeating decimal. Otherwise, it is an irrational number.

19/5: it is a rational number because it is in fraction form

√12: this is an irrational number

√49: this is a rational number because when you simplify this you will get the answer 7, that is a whole number.

0.3425563758: This is a decimal, hence, this is rational.

4/25 : it is a fraction so it is a rational number.

√1/8: this is an irrational number

√0.6¯: this is an <u>irrational number</u>

√12 irrational = 2 sqrt (3)

19/5 irrational cannot be simplified

√49 rational = 7

0.3425563758 if this is the last number rational if this continues irrational

√4/25 rational 2/5

√1/8 irrational = 1/(2sqrt(2))

0.6 rational

The net of a triangular prism is shown below. What is the surface area of the prism? A. 128 cm^2 B. 152 cm^2 C. 176 cm^2 D. 304

shtirl [24]

Answer:

B. 152 cm²

Step-by-step explanation:

To find the surface area using a net, do this:

Take apart the figure. We see that there are three rectangles and two triangles. Find the area of each ( $A=l*w$ ) and then add the values together:

The first rectangle on the left is the same as the one on the right.

$5*8=40$

Two measures are 40 cm².

The middle rectangle is:

$6*8=48$

48 cm²

The formula for the area of a triangle is $A=\frac{1}{2}*b*h$ :

$A=\frac{1}{2}*6*4\\\\A=\frac{1*6*4}{2}\\\\A=\frac{24}{2}\\\\ A=12$

The area of the two triangles is 12 cm².

Now add the values:

$40+40+48+12+12=152$

The area of the figure is 152 cm².

Kurt drives a total of 32 miles to and from work every day. He works 5 days a week. How many miles does Kurt drive in a week for

Naily [24]

Does Kurt drive 32 miles to work and 32 back home or does Kurt drive a combined total of 32 miles to and from work.

If he drive 32 miles to work and 32 home- Kurt would have driven a total of 64 miles each day. So if he works 5 days a week you would just use this simple equation: {64 x 5} which would get you 320 miles each week.

If he drives a combined total of 32 miles each day then you use this following equation: {32 x 5} which would get you 160 miles each week
