hii im sorry to be a burden but could someone please help me with this problem it has to do with the pythagorean theorem :p

Answer:

Step-by-step explanation:

10 inches

**Answer:**

68.5 inches

**Step-by-step explanation:**

The pythagorean theorem is a^2+b^2 = c^2

In this case, a = 60, b = 33, and we are looking for c, so this is how you do it:

60^2 + 33^2 = 3600 + 1089 = 4689

sqrt(4689) = 68.47627326...

Rounded to the nearest tenth is 68.5!

Consider angle B in the diagram below . What is the length of “opposite side” to angle B?

Answer: a

**Answer:**

8

**Step-by-step explanation:**

use pythagoras theorem

a^2+b^2=c^2

a^2+6^2=10^2

a^2=10^2-6^2

a^2=100-36

a^2=64

a=square root of 64

a=8

There are 4 blocks in the bag. How many of the 4 blocks do you think are red (R)? The graph shows the results of the first 10 picks.

3 blue one red good luck

**Answer: 1 Red Block**

**Step-by-step explanation:**

**2:8 is the existing ratio shown in the graph. And so I think if we divide both sides by 2 we get 1:4 which is what we want. So we take the 1 part which is red. 1 Red Block.**

brainliest, please help, The line PQ has equation y = 3x - 8 and point P has co-ordinates (6, 10). Find the equation of the line that passes through P and is perpendicular to PQ. Give your answer in the form y = mx + c.

The **equation of the line** that** passes through P** and is **perpendicular** to **PQ** is **y=-1/3x+12**.

Given that, the line PQ has equation y = 3x - 8 and point P has coordinates (6, 10).

We need to find the **equation** of the **line** that passes through **P**.

The **slopes** of **two perpendicular lines** are **negative** **reciprocals** of each other. This means that if a **line is perpendicular** to a **line** that has a **slope** of **m**, then the **slope** of the **line is -1/m**.

Here, the **slope** of the **equation** is **3**.

The **equation** of the **line** that **passes through P** and is **perpendicular** to **PQ is -1/3**.

Now, 10=-1/3(6)+c

⇒c=12

Thus, y=-1/3x+12

Therefore, the **equation of the line** that** passes through P** and is **perpendicular** to **PQ** is **y=-1/3x+12**.

An architect is making a plan for a new circular playground. If the picture below is the

playground, how much fencing needs to go up to

keep the kids in the circle?

**Answer:**

201ft

**Step-by-step explanation:**

The circumference of a circle is equal to

C=piD

d=64ft

substitute:

c=pi(64)=64pift ft

assume pi=3.14

64pi=64*3.14=200.96ft

round to the nearest whole number:

200.96=201ft

another explanation:

Answer:

Length of the fencing required = 201.06 meters

Step-by-step explanation:

Architect is planning a circular playground with diameter = 64 m

We have to calculate the fencing required to cover this playground.

Length of fencing = circumference of the playground

Since circumference of a circle = π × (Diameter)

= 64π

= 201.06 meters

Therefore, length of fencing required to keep the kids in a circle will be 201.06 meters.

200.96 meters of **fencing** needs to go up to keep the kids in the **circle**. Therefore, option D is the correct answer.

The **circumference** of a circle is the perimeter of the circle. It is the total length of the boundary of the circle. The circumference of a circle is the product of the constant π and the diameter of the **circle**.

Given that, diameter of a **circle** is 64 meter.

Here, the radius = 64/2

= 32 meter

We know that, the circumference of a circle can be calculated using 2πr.

Now, circumference = 2×3.14×32

= 200.96 meters

Therefore, option D is the correct answer.
