Phoenix [80]2 years ago

8 0

Answer:

option A

Step-by-step explanation:

take 45 degree as reference angle

using sin rule

sin 45 = opposite / hypotenuse

$\frac{1}{\sqrt{2} }$ = s/ $8\sqrt{2}$

$\frac{1}{\sqrt{2} } *8\sqrt{2}$ = s

root 2 and root 2 gets cancel

8 = s

A bag contains 5 red marbles, 8 blue marbles and 4 green marbles. If three marbles are drawn out of the bag, what is the probabi

Zarrin [17]

Step-by-step explanation:

step 1. let's assume they are drawn without replacement and probability is denoted P.

step 3. P = (5/17)(4/16)(3/15)

step 4. P = (5/17)(1/4)(1/5)

step 5. P = 5/340

step 6. P = 1/68 = 0.0147 = 1.5%

What is the surface area of the pyramid?

-Dominant- [34]

Answer:

166 square units

Step-by-step explanation:

Let’s find the area of the shapes that in the net.

First, we can see two of the triangles have a base of 2 and a height of 13. The formula for surface area of a triangle is bh÷2. (13x2)÷2=13. Since there are two triangles, we multiply 13 by 2 and get 26.

Second, we can see two of the triangles have a base of 10 and a height of 12. (10x12)÷2=60. Since there are two triangles, we multiply 60 by 2 and get 120.

Third, we can see a rectangle has a base of 10 and a height of 2. The formula for surface area of a rectangle is bh. 10x2=20.

Last, we add up all the areas:

20+120+26=166.

Answer:

Probably the first one Bc the rest are technically somewhat correct and I’d think just 3 would be the least accurate

There are a total of 120 bicycles and tricycles in a shop. There are 302 wheels in allmany bicycles and how many tricycles are i

Contact [7]

Answer: There are 62 tricycles in the shop.

Step-by-step explanation:

Given: Number of wheels in a bicycle = 2

Number of wheels in a tricycle = 3

Let x = Number of bicycles , y = Number of tricycles.

As per given , we have

x+y =120 (i)

2x+3y=302 (ii)

Multiplying 2 on both sides of (i)

2x+2y=240 (iii)

Subtract (iii) from (ii) , we get

y= 62

Put value of y in (i) , we get

$x+62=120\\\\\Rightarrow\ x=120-62\\\\\Rightarrow\ x= 58$

Hence, there are 58 bicycles and 62 tricycles in the shop.
