Answer:

The perimeter of the base is 13.1 centimeters

Step-by-step explanation:

we know that

The surface area of a triangular prism is equal to

SA=2B+Ph

where

B is the area of the triangular base

P is the perimeter of the triangular base

h is the length of the prism

we have

SA=117.3\ cm^2\\B=6.25\ cm^2\\h=8\ cm

substitute in the formula

117.3=2(6.25)+P(8)

solve for P

P(8)=117.3-12.50\\8P=104.8\\P=13.1\ cm

Martha made a mistake. In which step did Martha first make a mistake, and what is a correct expression for that step?
PtichkaEL [24]
We have  that
 f²{k^6/[k^4*k^3]}^-3

step 1
 f²{k^6/[k^(4+3)]}^-3---------> f²{k^6/[k^7]}^-3-------> step 1 is correct

step 2
 f²{k^6/[k^7]}^-3------>  f²{k^(6-7)]}^-3---->  f²{k^(-1)}^-3----> step 2 is correct

step 3
f²{k^(-1)}^-3------> f²{k^[(-1)*(-3)]}-----> f²{k^(3)}
therefore
Martha made a mistake in the step 3

the answer is
step 3
f²k³

Vinil7 [7]

Answer:

c. 10

Step-by-step explanation:

Pick any two points from the table. I chose (0, -20) and (1, -10)

Let's find the slope between your two points.

(0,−20) (1,−10)

(x1, y1)=(0, −20)

(x2, y2)=(1, −10)

Use the slope formula:

m=  y2 − y1  / x2 − x1

=  −10 − −20  / 1 − 0

=  10  / 1

= 10

Water is not a liquid if its temperature is above 100 °C or below 0 °C.

Answer:

0 \leq  x \leq  100

0, 40, and 80 are the values that work for this compound inequality.

Step-by-step explanation:

To create a compound inequality, we have to examine the conditions for x to work.

Since x can not be below 0° C, that means that x must be greater than or equal to 0.

Which is represented as x\geq 0, or 0\leq x.

Since x can not be above 100° C, that means x must be less than 100.

Which is represented as x \leq  100.

We can combine both inequalities into one, where x is shared between the two. This creates 0\leq x \leq 100.

Let's test each value of x .

0 is <em>equal to</em> 0 and less than 100, so it works.

40 is <em>greater  </em>than 0 and less than 100, so it works.

80 is <em>greater  </em>than 0 and less than 100, so it works.

120 is <em>greater  </em>than 0 and <em>greater</em> than 100, so it doesn't work.

160 is <em>greater  </em>than 0 and <em>greater</em> than 100, so it doesn't work.

Hope this helped!
