Find the value of x A- 6 B-5 C-4 D-10

Snezhnost [94]

Answer:

x=4

Step-by-step explanation:

In triangle MLK

it is a equilateral triangle
Hence
ML=LK=MK=5

Now come to triangle MKJ

It is a isosceles triangle
Hence
MJ=Mk

MK=5

Hence

$\longrightarrow\sf MJ=5$

$\longrightarrow\sf x+1=5$

$\longrightarrow\sf x=5-1$

$\longrightarrow\sf x=4$

A student determined that the area of the segment of c shown above is Asegment = 137.71 ft2. The student's work is shown below.

ivolga24 [154]

Answer:

Option D. The student did not use the correct formula to calculate the area of the segment

Step-by-step explanation:

step 1

Find the area of the isosceles triangle

Applying the law of sines

$A=\frac{1}{2}(12^{2})sin(60\°)=62.35\ ft^{2}$

step 2

Find the area of the sector

The area of the sector is 1/6 of the area of the circle

$A=\pi r^{2}/6$

substitute the value

$A=(3.14)(12)^{2}/6=75.36\ ft^{2}$

step 3

Find the area of the segment

The area of the segment is equal to the area of sector minus the area of triangle

$A=75.36\ ft^{2}-62.35\ ft^{2}=13.01\ ft^{2}$

therefore

The student did not use the correct formula to calculate the area of the segment

What the answer to this all of those

zvonat [6]

So much stuff at once...
I'm only going to give you the information needed to do this.

All of these involve the 4 main exponent laws.

1) Multiplying.
When you multiply two 'numbers' that share the same base, you add exponents and keep the base the same. (ex. 4g²(4g⁴) = 4g²⁺⁴ = 4g⁶)

2) Dividing.
When you divide two 'numbers' that share the same base, you subtract exponents and keep the base the same. (ex. 3a⁷ / 3a⁴ = 3a⁷⁻³ = 3a³)

3) To the power of 1.
Anything to the power of 1 is the same. (ex. 5a¹ = 5a)

4) To the power of 0.
Anything to the power of 0 = 1. (ex. 2d⁰ = 2(1) = 2)

This should help.

The weather forecast says there’s 70% probability of rain tomorrow. What are the odds against rain

krok68 [10]

Answer:

30%

Step-by-step explanation:

Key skills needed: Probability

1) There is a 70% chance of rain.

2) We need to find the chances against rain.

3) To do this, we need to use the fact that

70% + x = 100% (Since all the probabilities add up to 1 or 100%)

4) If you subtract 70% from both sides, x = 30%

5) This means the probability against rain is 30%.

Hope you understood and have a nice day!! :D
