To find the surface are of the base: 8 * 8 = 64/2(becasue its a triangle not a square base) = 32.
To find the surface are of the 3 other faces, 12 * 8 = 96/2 = 48 * 3(for the 3 sides) = 144.
The entire surface area is 176.
Answer:
Step-by-step explanation:
B. for it to be a proper function, it must pass the vertical line test (meaning, if you were to fill a continuous line between each of the dots, and then drew a string vertical line down at any point along the function, that vertical line cannot intersect with the function line more than once.
A, would fail the vertical line test, C< and D would also fail, as a vertical line would intersect/cross the function line more than once.
Answer:
Jennifer should expect a number less than 3 23 times
Step-by-step explanation:
The probability of rolling a number less than 3 on a number cube is 2/6. .
The probability of rolling a number less than 3 on a number cube is 2/6
= 1/3
Jennifer rolls a number cube 69 times
Expectations= probability*total outcome
Expectations= 1/3 * 69
Expectations= 69/3
Expectations= 23 times
Answer:
151 degrees
Step-by-step explanation:
∠3 and ∠4 are on a straight line, therefore they are supplementary. This means that they add to 180 degrees.
∠3+∠4=180
We are given the m∠3, it is 29, so we can substitute that in
29+∠4=180
We want to find the m∠4. To do this, we need to get ∠4 by itself. Subtract 29 from both sides, since 29 is being added to ∠4.
29-29+∠4=180-29
∠4=151
So, the m∠4 is 151 degrees
