Answer:

B. 3/4

Step-by-step explanation:

Trey's car has a 20-gallon fuel tank so 1/4 of 20 is 5 so you add the 10 and the 5 so you get 15. so 15/20 simplified is 3/4 which is answer choice B.

Answer:

If 1/4 of the gas tank is filled, then there are 5 gallons currently in the gas tank.

If 10 gallons are added to the gas tank, there will be 15 gallons in the gas tank, meaning that the gas tank will be 3/4 full.

Let me know if this helps!

Stephen says that the numbers 38 and 40 are relatively prime. Explain why he is incorrect in making this statement. (make a good

Paha777 [63]

Answer:

He is incorrect in this statement because 38 and 40 both have factors, other than 1 x itself. Prime numbers are numbers the only have 1 factor pair, and that is 1 x itself. Factors are the numbers you multiply to get the end result, and an example is 10x4=40. The factors of 40 are 8x5, 4x10, 2x20, and of course, 1x40. The factors of 38 are 2x19, and 1x38.

The diagram shows , , and . Which statement can be proven true from the diagram?

tresset_1 [31]

What can be proven true in the diagram is the statement in letter C. angle CGB is complementary to angle AGD. It is because they both had the same vertex which is point G. Complementary angles are angles which are equal to 90 degrees wherein when you add both angles which are obviously 45 degrees, the sum is 90 degrees.

The smallest integer that can be added to -2m3 − m + m2 + 1 to make it completely divisible by m + 1 is .

dangina [55]

Recall the polynomial remainder theorem: if $m-c$ is a factor of some polynomial $p(m)$ , then the remainder upon dividing $p(m)$ by $m-c$ is $p(c)$ .

Let $c=-1$ and $p(m)=-2m^3+m^2-m+1$ . The remainder left from dividing $p(m)$ by $m+1$ is

$p(-1)=-2(-1)^3+(-1)^2-(-1)+1=5$

If we subtract 5 from both sides, we'd get a "remainder" of 0, which suggests that we have to add -5 to $p(m)$ to make $m+1$ a factor.
