Answer:

21/41

Step-by-step explanation:

Find the total number of students

6+7+2+3+6+8+4+5=41

Then find the students that do not study chemistry

6+7+2+5 = 20

P( not study chemistry) = do not study chem)/total

                                       =21/41

Joe is finding the length of a rectangular prism. The volume of the prism is 204 ft3. The width is 3.5 ft, and the height is 5 f
zmey [24]

Answer:

B. He added 3.5 and 5 when he should have multiplied them.

Step-by-step explanation:

Let's observe Joe's steps:

- V = lwh

- 204 = 3.5 * (5) * l

Here, * means to multiply, so we're supposed to multiply 3.5 to 5, which would give you the answer 17.5. Unfortunately, look what Joe got: he obtained the value of 8.5, and if we observe, 3.5 + 5 = 8.5.

That's how we know that Joe added instead of multiplied, as he should have done. Thus, the answer is B.

What is 7 plus the sum of m and -17​
olasank [31]

Answer:

m - 10

Step-by-step explanation:

7 plus = 7 +

The sum of m and -17 = m + (-17)

7 + (m + -17)

We can get rid of the parentheses

7 + m + -17

Combine like terms

7 + -17 = -10

m + -10

Get rid of the addition sign

m - 10

SHORT RESPONSE Two angles of a triangle have measures of 35° and 80°. Find the values of the exterior angle measures of the tria
Oduvanchick [21]

Answer:

Step-by-step explanation:

Before giving the exterior angles, find the third angle. A triangle (all triangles) measure 180 degrees.

35 + 80 + x = 180

115 + x = 180

x = 180 - 115

x = 65

Exterior angles are supplements of the interior angles.

So the exterior angle to 65 degrees is 180 - 65 = 115

And the exterior angle to 35 degrees is 180-35 = 145

The exterior angle to 80 degrees is 180 - 100 = 80
