Answer:

Question 2 = 15 drinks

Question 3 = 7/12

Step-by-step explanation:

Question 2:

For every drink, there are three sizes

Ratio = 1:3

There are 5 flavors

Multiply each side by 5

5:15

15 drinks

Question 3:

5 red, 6 yellow, 8 blue, 3 orange, 2 purple

Possible outcomes = 5 + 6 + 8 + 3 + 2 = 24 possible outcomes

Favourable outcomes = 6 + 8 = 14 favourable outcomes

Fraction = 14/24 = 7/12

If my answer is incorrect, pls correct me!

A blimp is flying at a speed of 40mph and going in a direction of 80 degrees. After 3 hours of flying it turns and travels 1 hou

kykrilka [37]

Bearing is a topic that can be used to locate the position of an object at a given time. Therefore, the blimp is 80 m far away from its starting point. And in the North-East direction.

The speed of an object relates the distance it covers to the time taken to cover the said distance.

i.e speed = $\frac{distance}{time taken}$

⇒ distance = speed x time taken

In the given question, the initial distance covered can be determined as;

distance = 40 mph x 3 h

= 120 m

The final distance covered can be determined as;

distance = 40 mph x 1 h

= 40 m

Let the distance from its starting point to its final location be represented by x.

Thus applying the Cosine rule, we have:

$c^{2}$ = $a^{2}$ + $b^{2}$ - 2abCos C

$x^{2}$ = $120^{2}$ + $40^{2}$ - 2(120 x 40) Cos 90

= 14400 + 1600 - 9600

$x^{2}$ = 16000 - 9600

= 6400

x = $\sqrt{6400}$

= 80

x = 80 m

Therefore, the distance of the blimp from its starting point to its final destination is 80 m.

Write an expression to represent each of the following sketches. Then give the value of each sketch.

zysi [14]

The sketches are illustrations of inequalities

The first sketch is: $-2 \le x \le 5$ .
The second sketch is: $3 \ge x \ge -4$

Sketch A

In sketch A, we have the following observations:

The arrow faces left (this implies less than)
The dots on -2 and -5 are closed dots (this implies less than or equal to).

Hence, the inequality is:

$-2 \le x \le 5$

Sketch B

In sketch B, we have the following observations:

The arrow faces right (this implies greater than)
The dots on -4 and 3 are closed dots (this implies greater than or equal to).

Hence, the inequality is:

$3 \ge x \ge -4$
