Answer:

i. Time = 2 hours.

ii. Average speed for the whole journey = 25 km/h

Step-by-step explanation:

Distance from Antville to Beetleton = 60 km

Mr. Caterpillar's speed = 30 km/h

Speed = $\frac{distance}{time}$

⇒ time = $\frac{distance}{speed}$

= $\frac{60}{30}$

= 2

time = 2 hours

It would take Mr. Caterpillar 2 hours to travel from Antville to Beetleton at that speed.

On his return journey, his average speed is 20 km/h. Therefore;

average speed for the whole journey = $\frac{30 + 20}{2}$

= $\frac{50}{2}$

= 25

average speed for the whole journey = 25 km/h

Answer:

1 more slice

Step-by-step explanation:

1/2 of the pizza would be 4 since (8÷2=4)

So since we need 4 pizza slices to be gone in order to make 1/2 of the pizza...

and since we know that there are three slices missing....

the equation for this is 8-3=5 and we can't have 5 we need 4 so we need 1 more slice to be eaten

Find the missing angles. will give brainliest if done correctly.

NISA [10]

Answer:

Step-by-step explanation:

the sum of the interior angles in a triangles is 180°, take away from 180 the know angles (34° and 77°) and you will have your answer

180 - 34 - 77 = 69°

Now we find angle V

The angle V and the angle of 77 ° are on a straight line, so the sum is 180°, from 180° you subtract 77 ° and you have the value of V

180 - 77 = 103 °

Explain how you would create and use a spinner to simulate the probability of an event with the following probabilities:

castortr0y [4]

To simulate the probability in a spinner divide the spinner into colors depending on the probability each color represents.

<h3>What does the word "probability" mean?</h3>

This word refers to the likelihood for an event to occur. Moreover, it is often expressed either as a fraction, a percentage, or a number.

<h3>How to create a spinner to simulate probability?</h3>

In this case, each of the colors represents a probability:

Green 20%
Blue 1/4 or 25%
Yellow 2/5 oe 40%
Orange 15%

Due to this, the best is to divide the spinner by colors and considering the percentanges of each color. For example 40% of the spinner should be red, while 15% should be orange.
