What is the greatest common factor if 9 and 15

Answer:

True

Step-by-step explanation:

Let A denotes the point (1,7)

Let B denotes the point (5,5)

We are supposed to find The length of the line segment containing the points

Formula : [tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

[tex](x_1,y_1)=(1,7)\\(x_2,y_2)=(5,5)\\ d = \sqrt{(5-1)^2+(5-7)^2}\\ d = \sqrt{4^2+(-2)^2}\\ d = \sqrt{4^2+(-2)^2}\\d=4.47[/tex]

So,The length of the line segment containing the points (1,7) and (5,5)  is 4.47 units is true.

Hence Option A is true

Hey!

Your answer is 56 miles!

Step-by-step explanation:

To find speed, we do 294 divided by 5hrs and 15mins (5.25)

So next= 294 / 5.25

Which gives us 56 mph!

HOPE THIS HELPS!!

The car travel 56 miles per hour.

The speed can be defined as the rate at which an object covers some distance.

Here, we know that,

Speed = Distance / Time

Now, Distance = 294 miles

         Time = 5 hours and 15 minutes

                  = 5.25 hours.

Now, Speed = 294 / 5.25

                     = 56 miles per hour.

Thus, the car travel 56 miles per hour.

Answer: option A is correct

Step-by-step explanation:

The given side lengths are

A) 5, 12, 13

B) 4, 4, 8

C) 2, 3, 4

To be able to form a right ange triangle, the given side lengths must be a Pythagorean triple. Pythagorean triple obeys the Pythagorean theorem such that

Hypotenuse² = opposite side² + adjacent side²

Hypotenuse = the longest side

Applying it to the given options,

A) 13² = 5² + 12² = 25 + 144

169 = 169

It forms a right angle triangle

B) 8² = 4² + 4² = 16 + 16

64 ≠ 32

It does not forms a right angle triangle

C) 4² = 3² + 2²

16 ≠ 13

It does not forms a right angle triangle

Answer:

Option A) 5, 12, 13 is a right angle triangle.

Option C) 2, 3, 4 is approximately a right angle triangle.

Step-by-step explanation:

A right angle triangle always follow pythagora's theorem which basically states that the addition of the squares of the two smaller sides must give the square of the largest side.

For option A)

5^2 + 12^2 = 25 + 144 = 169

Square root of 169 is 13, so it's correct.

For option B)

4^2 + 4^2 = 16 + 16 = 32

Square root of 32 is 5.65, which is not equal to 8. This is not a right angle triangle.

For option C)

2^2 + 3^2 = 4 + 9 = 13

Square root of 13 is 3.606, approximately 4. So this is approximately a right angle triangle.

If the answer requires that it must be exact then choose only A, Otherwise, A and C are correct.

There are 20 rosebushes, Juanita painted 3/4 of them.

So, we can convert 3/4 into a decimal or just multiply it by 20 to get the number of rose bushes that were painted red. Either way works.

Work:

20 x 3/4 = 15

3/4 = .75

.75 x 20 = 15

20 - 15 = 5

Therefore, 15 rosebushes were painted red and 5 rosebushes were painted white.

Answer:

He can make 2 batches of lemonade with 1 pint of lemon juice.

Step-by-step explanation:

First convert 1 pint to ounces

1 pint of lemon juice = 16 fluid ounces

To get the number of batches  that can be made with 1 pint (16 fluid ounces) of lemon juice, we can simply use proportion;

Let x be the number of batches Farid can make with 1 pint(16 fluid ounces) of lemon juice

8 fluid ounces = 1 batch

16 fluid ounces = x

cross-multiply

8x = 16

Divide both-side of the equation by 8

8x/8 = 16/8

x= 2 batches.

Therefore, he can make 2 batches of lemonade with 1 pint of lemon juice.

He can make 2 batches of lemonade with 1 pint of lemon juice.

Given that,

Farid uses 8 fluid ounces of lemon juice in one batch of lemonade.

We have to determine,

How many batches can he  make with 1 pint of lemon juice?

According to the question,

First, convert 1 pint to ounces

1 pint of lemon juice = 16 fluid ounces

To find the number of batches that can be made with 1 pint (16 fluid ounces) of lemon juice, the equation can be simplified by using proportion;

Let, x be the number of batches Farid can make with 1 pint (16 fluid ounces) of lemon juice.

8 fluid ounces = 1 batch

16 fluid ounces = x batch

Solving the equation by cross multiplication,

[tex]\dfrac{8}{16} = \dfrac{1}{x}\\\\8x = 16\\\\x = \dfrac{16}{8}\\\\x = 2[/tex]

Therefore, he can make 2 batches of lemonade with 1 pint of lemon juice.

Answer: Mean of the sample proportion = 74.4

Standard deviation of the samnple proportion is 5.32.

Step-by-step explanation:

Given : A random sample of 120 is taken from a population of 10000.

Let n = 120

Also, from previous survey, it is believed that 62% of the population has an Instagram account.

i.e, population proportion : p = 0.62

Now , the mean of the sample proportin would be :

[tex]\text{Mean}=\mu_{\hat{p}}=np\\\\=120\times0.62=74.4[/tex]

i.e. Mean of the sample proportion = 74.4

The standard deviation of the samnple proportion would be :

[tex]\text{standard deviation}=\sigma_{\hat{p}}=\sqrt{np(1-p)}\\\\=\sqrt{120(0.62)(1-0.62)}\\\\=\sqrt{28.272}\\\\=5.31714208951\approx5.32[/tex]

Answer:

5. 34°

6. 29.7

Step-by-step explanation:

5. Using sine law

25/sin(93) = 14/sin(C)

sin(C) = 0.5592325395

C = 34.00273934°

6. Using cosine law

AC² = 23.2² + 18.1² - 2(23.2)(18.1)cos(91)

AC² = 880.507229

AC = 29.67334206

Answer:

5. m∠C ≈ 34°

6. AC ≈ 29.7 metres

Step-by-step explanation:

5. We need to use the Law of Sines here, which says that for a triangle with sides a, b, and c and angles A, B, and C:

[tex]\frac{a}{sinA} =\frac{b}{sinB} =\frac{c}{sinC}[/tex]

Here, a = 25, ∠A = 93°, and c = 14, so we want to find ∠C:

[tex]\frac{a}{sinA} =\frac{b}{sinB} =\frac{c}{sinC}[/tex]

[tex]\frac{25}{sin93} =\frac{14}{sinC}[/tex]

sinC ≈ 0.56

∠C ≈ 34°

6. We need to use the Law of Cosines here, which says that for a triangle with sides a, b, and c and angles A, B, and C:

[tex]c^2=a^2+b^2-2abcosC[/tex]

[tex]b^2=a^2+c^2-2accosB[/tex]

[tex]a^2=b^2+c^2-2bccosA[/tex]

Here, a = 23.2, c = 18.1, ∠B = 91°, and b = x. We want to find b, so:

[tex]b^2=a^2+c^2-2accosB[/tex]

[tex]x^2=23.2^2+18.1^2-2*23.2*18.1*cos(91)[/tex] ≈ 880.5

x ≈ 29.7 metres

Answer:

x = 26.45

Step-by-step explanation:

Switch the x and the cos 50

x = 17 / cos 50

x =26.44730506

Rounding to 2 decimal places

x = 26.45
