It can be noted that the diameter will be 4.26 inches.

From the information given, the area has been given as 14.18 square inches.

Therefore, the diameter will be calculated thus:

πr²= 14.18

3.14 × r² = 14.8

r² = 14.18/3.14

r² = 4.5

r = 2.13

Therefore, the diameter will be;

= 2r

= 2 × 2.13

= 4.26 inches.

Answer:

101.4 floz

Step-by-step explanation:

If I'm correct, you should multiply 16.9 by 6 because there are 6 bottles and each has 16.9 fluid ounces of water.

A water bottle has 16.9 fluid ounces of water, there would be a total of 101.4 fluid ounces of water.

We are given that each water bottle contains 16.9 fluid ounces of water. This is the capacity or volume of a single bottle.

To find the total amount of water in a pack of 6 bottles, we can multiply the amount of water in one bottle by the number of bottles in the pack.

Amount of water in one bottle: 16.9 fluid ounces

Number of bottles in the pack: 6

Total amount of water in the pack: 16.9 fluid ounces/bottle * 6 bottles = 101.4 fluid ounces

Therefore, there would be a total of 101.4 fluid ounces of water in a pack of 6 bottles.

Answer:All non-negative integers less than 70 for f(n) and All integers greater than or equal to 70

Step-by-step explanation:

It asks about the price before and after the free delivery.I’m not the best at explaining but I hope my answer helped.

The domain of the given functions are required.

The domain of [tex]f(n)[/tex] is All non-negative integers less than 14.

The domain of [tex]g(n)[/tex] is All integers greater than or equal to 14.

When the order is less than $70 a delivery charge of $89 is added and each plant costs $5.

The function representing the situation is

[tex]f(n)=89+5n[/tex]

If the order is or more than $70 then the function will be

[tex]g(n)=5n[/tex]

The domain of a function is the permissible values of [tex]n[/tex] for which the function is valid.

In the first function the number of plants that need to be bought so that the order will be 70 dollars would be

[tex]\dfrac{70}{5}=14[/tex]

So, only if less than 14 plants are bought then the first function can be used.

Also, the number of plants cannot be negative or zero hence it will be positive.

So, the domain of [tex]f(n)[/tex] is All non-negative integers less than 14.

In the second function the number of plants has to be 14 or more as it costs 70 dollars or more.

So, the domain of [tex]g(n)[/tex] is All integers greater than or equal to 14.

h=20.4

Step-by-step explanation:

=> 7780.05 = 28.25 x 13.5 x h

multiply h by 13.5

=> 7780.05 = 28.25 x 13.5h

make h the subject of formula

=> 13.5h × 28.25 = 7780.05

Let's solve your equation step-by-step.

=> 13.5h(28.25)=7780.05

Step 1: Simplify both sides of the equation.

=> 381.375h=7780.05

Step 2: Divide both sides by 381.375.

=>[tex] \frac{381.375h}{381.375}= \frac{7780.05}{381.375}[/tex]

Answer:

i

Step-by-step explanation:

is this my question answer?

Answer:

Kindly check explanation

Step-by-step explanation:

Given the data : 5, 9, 10, 11, 15

s = √[(ΣX - m)² / (n - 1)]

n = number of sample = 5

m = mean

m = ΣX/n

m = (5 + 9 + 10+ 11 + 15) / 5

m = 50/5 = 10

s =√((5-10)^2 + (9-10)^2 + (10-10)^2 + (11-10)^2 + (15-10)^2) / 5-1

= 3.601

(B) Multiply each data value by 5 to obtain the new data set 25, 45, 50, 55, 75. Compute s.

m = ΣX/n

m = (25 + 45 + 50 + 55 + 75) / 5

m = 250/5 = 50

s =√((25-50)^2 + (45-50)^2 + (50-50)^2 + (55-50)^2 + (75-50)^2) / 5-1

= 18. 028

(c) Compare the results of parts (a) and (b). In general, how does the standard deviation change if each data value is multiplied by a constant c?

The standard deviation changes by almost c times multiplied by the initial value.

3.601 * 5 = 18.005 which is almost equivalent to 18.028

(d) You recorded the weekly distances you bicycled in miles and computed the standard deviation to be s 3.1 miles. Your friend wants to know the standard deviation in kilometers. Do you need to redo all the calcula- tions?

No

Given 1 mile 1.6 kilometers, what is the standard deviation in kilometers?

If 1 mile = 1.6km

s = 3.1 miles

s in kilometers = (1.6 * 3.1) = 4.96km

Answer:

[tex]A. 10\sqrt{2}[/tex]

Step-by-step explanation:

The triangle is a 45-45-90 triangle, which has the property that the side across from the 90°, in this case, x, is equal to one of the other sides multiplied by [tex]\sqrt{2}[/tex].

So:

10 x [tex]\sqrt{2}[/tex] = [tex]10\sqrt{2}[/tex]

The value of x in the given triangle is 10√2. So, correct option is A.

In triangle ABC, since angle B is a right angle, we can use the Pythagorean theorem to find the length of side AC (denoted by x).

The Pythagorean theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

In this case, AB and BC are the two sides adjacent to the right angle:

AB² + BC² = AC²

Substitute the given values:

10² + 10² = x²

100 + 100 = x²

200 = x²

Now, to find the value of x, take the square root of both sides:

x = √200

Simplify the square root:

x = √(100 * 2)

x = 10√2

So, the value of x in the triangle is 10√2.

The correct answer is A: 10√2.

1)

Take 12x as a common factor

12 since both 36 and 24 are divisible by 12

2)

Take 12x as a common factor again

12x(x-2)

3)

Take 15x as a common factor

15x(3x²-2)

3x²-2 can be written as the difference of 2 squares

15x(√3 x+√2)(√3 x-√2)

Answer:

[tex]12x(3x-2); 12x(x-2); 15x(3x^2-2)[/tex]

Step-by-step explanation:

Look at the coefficients of the first espression. 36 and 24 are both multiples of 12. We can collect 12x from both and we get

[tex]36x^2-24x=12x(3x-2)[/tex]

Second, 12 and 24 are obviously one twice the other, the common factor is again 12x:

[tex]12x^2-24x = 12x(x^2-2)[/tex]

Third polynomial: this time the greatest common divisor of 45 and 30 is 15. Let's collect 15x from either

(First Option): 2 over 3 tablespoon of vinegar is mixed with every tablespoon of olive oil

Step-by-step explanation

For every 2 tablespoons of vinegar, it was mixed with 3 tablespoons of olive oil. This leads to a ratio of 2:3, and that rules out option 2 and 3. To get the unit rate we divide 2 tablespoons of vinegar by 3 tablespoons of olive oil. This means that there is 2/3 tablespoons of vinegar for every tablespoon of olive oil and leads it to be answer choice 1.
