Answer:

\frac{9}{20}

Step-by-step explanation:

experimental probability is the probability of an event occuring when we perform an experiment.

It goes according to the results of the experiment, not the theory behind it.

<u>Probability of landing tails up, therefore, is the number of times it came tails up divided by the total number of times the coin was flipped.</u>

<u />

Hence

P (tails) = 36/80 = 9/20

The distance between Joshua's home and school is 800 m. Joshua takes 5 min to walk
Fynjy0 [20]

Answer:

= 0.38 m/s

Step-by-step explanation:

▪Total distance = 800 m

5 min = 100 m

▪Remaining distance = 800 - 100 = 700 m

20 min = 700 m

▪Total time taken = 20 + 10 + 5 = 35 min

If 1 min = 60 sec

What about 35 min = ?

= 35 x 60

= 2100 sec

▪Average speed = TD ÷ TT

= 800 ÷ 2100

= 0.38 m/s

A carpenter is building a unique jewelry box in the shape of a right triangular prism. The base has measurements of 4 inches, 3
BlackZzzverrR [31]
Answer: The carpenter will need 84 square inches of wood.

In this problem we are looking for the surface area of the jewelry box. This box has 5 faces. The two triangles at each end and the 3 rectangle pieces between them.

The sides of the triangles are 3, 4, 5 which always forms a right triangle with legs of 3 and 4. Use the formula for the area of a triangle, we have 3 x 4 / 2 = 6. The area of each triangle is 6 square inches.

Now, the three sides, each one has a height of 6.
3 x 6 = 18
4 x 6 = 24
5 x 6 = 30

If we add all the sides together, we get an area of 84 square inches.
6 + 6 + 18 + 24 + 30 = 84

Diagram 2 shows a piece of rectangular card in grey colour
Ilya [14]

Solution:

we have given the length of the rectangular card-

x + 5  \: cm

and, width-

7 \: cm

now, the area of the card will be- length×width.

so, we have-

(x + 5) \times 7 \: cm^{2}  \\ 7x + 35 \: cm^{2}

we also have given the length of ribbon-

7 \: cm

and, width-

y \: cm

so, area of the ribbon is-

length×width

7 \times y \: cm^{2}  \\ 7y \: cm^{2}

now the area of shaded gray region will be-

7x + 35 - 7y

Hence, the required expression would the above expression.
