Hi pls answer the following 4 questions ​
Will mark as brainliest for the best answer

Answer: Hi!

Answers B and D are correct.

For B, since negative numbers are on the left side of the number line, a positive number would have to be to the right of a negative number. Since we are adding a negative and a positive number of the same absolute value (9), they would cancel out to 0, which makes D true.

Hope this helps!

Hi there! Hopefully this helps!

-----------------------------------------------------------------------------------------------------

Explanation for D: -9 + 9 = 0.

Explanation for B: Negative numbers are on the LEFT side of the number line.

And positive numbers are on the right.

Therefore, 9 is to the RIGHT of -9 on the numberline.

Answer:

Option (A)

Step-by-step explanation:

It has been given in this question that sign telling path has a 2% grade.

2% grade means a rise of 2 meters for a horizontal change of 100 m (As given in the figure attached).

All the trigonometric ratios for the angle θ between the path and the horizontal are,

Sinθ = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

Cosθ = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

tanθ = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

Since measures of the opposite side and adjacent sides are given

Therefore, tangent ratio will be applied to get the measure of the angle,

tanθ = [tex]\frac{2}{100}[/tex]

θ = [tex]\text{tan}^{-1}(\frac{2}{100})[/tex]

Option (A) will be the answer.

Hi

draw 1 :  4/12 = 1/3

draw2 :  3/11

draw 3 : 5/10 = 1/2

so probability to have  :  1 banana then 1 apple then 1 orange  is :  1/3*3/11*1/2 =  3/66 =  3*1 / 2*3*11 =  1/22

Answer:

1/22

Step-by-step explanation:

Work out the probability of selecting each fruit then times them together so

there are 12 fruits in total and 4 bananas so the chance of selecting a banana is 4/12 simplified 1/3

then as you dont put the banana back there is only 11 fruits left in the basket and 3 are apples so the chance of selecting an apple is 3/11

then as you dont put the apple back there is only 10 fruit left in the basket and 5 are oranges so the chance of selecting an orange is 5/10 simplified 1/2

then we multiply them all together 1/3 x 3/11 x 1/2 3/66 to get which simplifies to 1/22

Answer:

x = 25

Step-by-step explanation:

The measure of angle A is 108°

An angle is formed when two straight lines or rays meet at a common endpoint.

Supplementary angles are those angles that sum up to 180 degrees.

Given that angle A and angle B are supplementary angle

∠A=(7x+10)°

∠B=(7x−26)°

(7x+10)° + (7x−26)° =180°

14x - 16° =180°

14x =196°

x= 14°

∠A=(7x+10)°

∠A=(7(14) +10)°

∠A= 108°

Thus the measure of angle A is 108°

==========================================

There are 3 methods to find the lowest common multiple (LCM)

---------------------------

Method 1

List out the multiples of 6 and 8

multiples of 6 = {6, 12, 18, 24, 30, 36, 42, 48, ...}

multiples of 8 = {8, 16, 24, 32, 40, 48, ...}

We see that 24 is the smallest number in both sets at the same time. So this is the LCM.

---------------------------

Method 2

Write the prime factorization of 6 and 8

prime factorization of 6 = 2*3

prime factorization of 8 = 2*2*2

The unique prime factors here are 2 and 3. We have 2 show up at most three times meaning that 2*2*2 = 8 is a factor of the LCM. The number 3 is also a factor meaning that 8*3 = 24 is the LCM.

---------------------------

Method 3

Multiply the denominators 6 and 8 to get 6*8 = 48

48 is a common multiple, but its not the smallest

we can divide 48 over the GCF 2 to get 48/2 = 24, which is the actual LCM.

So when you have 2 different denominators, you can multiply their values and then divide by the GCF to get the LCM.

Answer:

Step-by-step explanation:

a n = a 1 r n − 1

Answer:

The length r can be found using the Law of sines.

Length r = 14.8

Step-by-step explanation:

The length r can be found using the Law of sines.

The formula for the Law of Sines states that:

a/Sin A = b/ Sin B

In the above question,

∠P = 27°

∠R = 135°

p = 9.5

r = ????

The formula =

p/Sin P = r/Sin R

9.5/Sin 27° = r/Sin 135°

Cross Multiply

r × Sin 27° = 9.5 × Sin 135°

r = 9.5 × Sin 135°/Sin 27°

r = 14.7966

Approximately Length r = 14.8

Answer:

102.5, 103.5

Step-by-step explanation:

a+a+1=206

2a+1=206

2a=205

a=102.5

103.5

I think there is a bug here. They can't be whole numbers.

Answer:

There are no two consecutive whole numbers that sum to 206 (See proof below)

Step-by-step explanation:

let the first number be x

since the numbers are whole and consecutive, the second number must be (x + 1)

we are given that the number sum to 206

hence,

x + (x+1) = 206

x + x + 1 = 206

2x + 1 = 206  (subtract 1 from both sides)

2x = 206 - 1

2x = 205  (divide both sides by 2)

x  = 205/2 = 102.5  (NOT A WHOLE NUMBER)

if x = 102.5, then the second number must be

x + 1 = 102.5 + 1 + 103.5 (ALSO NOT A WHOLE NUMBER)

Answer:

90 dollars. The total will be $1,590.00.

Step-by-step explanation:

6% of 1500 is 90

We start by converting 6% to a fraction :

6% = 3/50  

Then we have

6% of 1500 = 3/50 x 1500 = 3/50 x 1500/1 = 4500/50

Notice that 1500 was rewritten as the fraction 1500/1, and that to multiply two fractions together, you simply multiply the numerators and denominators.

In order to find the simplest form of the fraction 4500/50 we cancel out the greatest common divisor of 4500 and 50, which is 50 :

4500/50=90/1

So the final answer is

6% of 1500=90
