Answer:

B. 4, Heads

4, Tails

5, Heads

5, Tails

6, Heads

6, Tails

Step-by-step explanation:

Given that the cube is labelled 1 to 6 and the coin has a head or a tail, the only outcome when the number cube lands on a number greater than 3 means that the cube lands on 4 or 5 or 6.

On the other hand, the coin may give a head or a tail.

In light of this, the possible answers are;

4, Heads

4, Tails

5, Heads

5, Tails

6, Heads

6, Tails

Hence option B is right

What is the measure of EDH? 10° 40° 50° 90°

Katyanochek1 [597]

In this exercise, we need to find the angle ∠EDH, that is, according to the figure above, this angle is:

∠EDH = (5x)°

So, our goal is to find the value of x. By taking a look in the figure above, this equation is true:

(5x)° + (4x)° = 90°

Therefore:

(9x)° = 90° ∴ x = 10

So:

∠EDH = (5x)° ∴ ∠EDH = [(5)(10)]° ∴ ∠EDH = 50°

Finally, the right answer is 50°

Find the measure of angle x in the figure below A.35° B.47° C.51° D.62°

Dafna11 [192]

First of all, we know that a line is 180°. This means if we add the angles of 61°, 57°, and angle y, we should get 180°.

$\sf 61\textdegree +57\textdegree+y=180\textdegree$

Simplify:

$\sf 118\textdegree +y=180\textdegree$

Subtract 118° to both sides:

$\sf y=62\textdegree$

We also know that all three angles of a triangle add up to 180°. So we have:

$\sf 67\textdegree+62\textdegree +x=180\textdegree$

Simplify:

$\sf 129\textdegree +x=180\textdegree$

Subtract 129° to both sides:

$\sf x=\boxed{\sf 51\textdegree}$

Item 15 Write and solve an equation to find the number n. Eight plus the quotient of a number and 3 is −2. Equation: =−2 The num

BabaBlast [244]

Answer:

n = - 30

Step-by-step explanation:

Eight plus the quotient of a number and 3 is −2

Expressing in mathematical terms, we have;

8 + (n/3) = -2

To solve for n;

Multiply all through by 3.

3*8 + 3(n/3) = 3 * (-2 )

24 + n = - 6

n = -6 - 24

n = - 30
