Which describes the cross section of the square prism that passes through the vertices A, B, C, and D shown

sasho [114]

Answer:

first of all,

Step-by-step explanation:

In triangle ABC one side equal and two sides equal

Step-by-step explanation:

We are given a prism whose base is square with sides 8 in and height 12 in.

If we take cross section through vertices A, B and C

We will get a cross section as triangle.

In triangle ABC, sides are AB, BC and AC

AB is diagonal of top square whose side 8 in.

AC is face diagonal of front face.

BC is face diagonal of right face.

AC=BC≠AB

Hence, In triangle ABC one side equal and two side equal

Which of the following points is a solution of y > Ixl + 5?

Step2247 [10]

Answer:

B. (1,7)

Step-by-step explanation:

We can substitute the x and y values of each coordinate into the inequality and test if they work.

Let's start with A, 5 being y and 0 being x .

$5 > |0|+5\\5> 0+5\\5 > 5$

5 IS NOT greater than 5, they are the exact same, so A is out.

Let's try B, 1 being x and 7 being y.

$7 > |1| + 5\\7 > 1 + 5\\7 > 6$

7 IS greater than 6, so B. (1,7) does work for this inequality!

Let's do C for fun, when 7 is x and 1 is y.

$1 > |7| + 5\\1>7+5\\1>12$

1 IS NOT greater than 12, it is quite less than 12, so C doesn't work.

Therefore B. (1,7) works for the inequality of $y > |x|+5$ .

Hope this helped!

If Mike does his mathematics homework today, the probability that he will do it tomorrow is 0.8. The probability that he will do

harina [27]

Answer:

d. 14:11

Step-by-step explanation:

There is a 7 in 10 chance that Mike does his homework today and a 8 in 10 chance he will do it tomorrow, the probability that he will do it both today and tomorrow is:

$P = \frac{7}{10}* \frac{8}{10}\\P=\frac{56}{100}=0.56$

The odds are the probability that an event occurs over the probability that it does not occur:

$Odds = \frac{0.56}{1-0.56}=\frac{56}{44}=\frac{14}{11}$

The odds that he will do it both today and tomorrow are 14:11.

The equation of a line is y= -1/2x - 2. What is the equation of the line that is perpendicular to the first line and passes thro

Fed [463]

If two line are perpendicular. The multiply of their slopes are equal to -1.
First line's slope is: -1/2x because if the line equation is form of y=ax+b a is slope.
Let say second line's slope is m
m.-1/2=-1 so m=2
y=ax+b is general form of linear function/equation. (a=slope)
y=2x+b
If this line passes through the point (2,-2),if we write -2 to y and 2 to x, the equation becomes true.
-2=4+b
b=-6
Thus,
y=2x-6 is true answer.
