Step-by-step explanation:

Given :-

To Find :-

Solution :-

As we know that,

Finding Slant height:

➝ L = √r² + h²

➝ L = √(16)² + (12)²

➝ L = √256 + 144

➝ L = √400

➝ L = 20 cm

Now,

Substituting the required values,

➝ LSA = 22/7 × 16 × 20

➝ LSA= 7040/7

➝ LSA ≈ 1005 cm²

Hence,

Answer:

0.00638

Step-by-step explanation:

Use some dimensional analysis. There are 60 minutes in 1 hour, and 60 seconds in 1 minute:

[tex] \frac{23}{1} \frac{units}{hour} \times \frac{1}{60} \frac{hour}{minutes} \times \frac{1}{60} \frac{minute}{seconds} [/tex]

The units of hour will cancel, minutes will cancel, leaving the units of seconds:

[tex] \frac{23}{60\times 60} \frac{units}{seconds} = 0.00638 \frac{units}{second} [/tex]

First of all we need to find the equations of the lines :

y( red ) = - x + 2

y(blue) = 2x - 1

Then we must to put the equations equal to each other and going to to find the value of x :

[tex]- x + 2 = 2x - 1[/tex]

Add both sides x

[tex] - x + x + 2 = 2x + x - 1[/tex]

[tex]2 = 3x - 1[/tex]

Add both sides 1

[tex]2 + 1 = 3x - 1 + 1[/tex]

[tex] 3 = 3x[/tex]

Switch sides

[tex]3x = 3[/tex]

Divide both sides by 3

[tex] \frac{3x}{3} = \frac{3}{3} \\ [/tex]

[tex]x = 1[/tex]

After u the value of x , put it in one the equations to find the value of y :

[tex]y = - x + 2[/tex]

[tex]y = - (1) + 2[/tex]

[tex]y = - 1 + 2[/tex]

[tex]y = 1[/tex]

Thus the solution is ( 1 , 1 ) .

Answer:

A: 5 cm2

B: 9 3/8 cm2

Step-by-step explanation:

Question A:

4 x 1 1/4

4/1 x 5/4 = 20/4

20/4 = 5 cm2

Question B:

3 3/4 x 2 1/2

15/4 x 5/2 = 75/8

75/8 = 9 3/8 cm2

3(3x−5)

(3 times 3x)(3 times -5)

9x-15

Since you don't know what x is, you can't simplify it any more than this.

Hey there!

Use the Distributive Property to simplify the expression 3(3x - 5) :

9x - 15 ✅

- Distributive Property :

A(B - C) = AB - BC

- Given expression :

3(3x - 5)

>> Distribute the 3 to the 3x and to the 5 :

3(3x - 5)

= 3*3x - 3*5

Therefore, your answer is 9x - 15 .

Have a good day ;)

k = 30/1

The constant of proportionality is 30:1. If we divided the number of area to be covered and the number of scoops, we will always get 30. 60/2 is 30, 120/4 is 30. 180/6 and 240/8 all equal 30.

Answer:

She drinks 4.5 oz in 1 hour.

Step-by-step explanation:

First,

1/2 of 6 would be 3

Shawnte drinks 3 ounces of water in 2/3 hrs.

3 oz = 2 / 3 hr

Multiply both sides by 3 to get 2 alone.

3*(3 oz) = 3*(2/3 hr)

9 oz = 2 hrs

She drinks 9 ounces of water in 2 hours.

9 / 2 oz = 2 / 2 hrs

Divide both sides by 2 so you can get how much she drinks in one hours

4.5 oz = 1 hr

Answer:

  legs limit the number of chairs that can be built

Step-by-step explanation:

The maximum number of chairs that can be built will be the minimum of the number of parts divided by the number of parts needed for each chair, as computed across the different kinds of parts required.

  seats: 12 available, used 1 per chair: 12/1 = 12 chairs possible

  backs: 15 available, used 1 per chair: 15/1 = 15 chairs possible

  legs: 44 available, used 4 per chair: 44/4 = 11 chairs possible

The maximum number of chairs that can be built will be the minimum of 12, 15, and 11. That is, 11 chairs can be built, limited by the number of available legs.

Answer:

With Outlier:

Median: 85
Mean: 103
Mode: 85

Without Outlier:
Median: 85
Mean: 85
Mode: 85

Step-by-step explanation:

Basically order the numbers from least to greatest. Include the outlier to find the median, mean, and mode. The median is clear as day with the outlier, being the middlemost number: 77, 84, 85, 85, 88, 91, 211. To find the mean, just add all of the numbers together and then divide them by how many numbers there are. In this case, that'd be 7 and you get 103. The mode is simple as it's the number that repeats the most, which is basically 85 since it repeats twice in the set. After you find the median, mean, and mode with the outlier, now rewrite the numbers (still least to greatest) but excluding the outlier (211). It should now be 77, 84, 85, 85, 88, 91. For the median, our middlemost numbers are 85 and 85, so simply just add them together and then divide by two. This gets you 85 for the median. For the mean, simply just add the numbers in the new set excluding the outlier and divide by 6 since that's how many numbers we have in the set now. This gives you 85. The mode is the number most repeated, and that's still 85.

__________________________________________________________

Hello! In this question, we will be changing our given equation to turn it into slope-intercept form.

__________________________________________________________

Explanation:

We are given the following equation:

3y − 3x = 15

Our goal is to turn the equation into slope-intercept form, which is:

y = mx + b

Let us rearrange the equation and simplify it:

3y − 3x = 15

Add 3x to both sides, which would cancel the 3x on the left.

3y = 3x + 15

Now, divide everything by 3 to get the "y" variable by itself.

y = x + 5

Therefore, your simplified equation in slope-intercept form would be:

y = x + 5

__________________________________________________________

Answer:

y = x + 5

__________________________________________________________

Part I: Reviewing the slope intercept form equation

Given equation:

Slope intercept form: y = mx + b

[Where "m" is the slope and "b" is the y-intercept]

Part II: Isolating "y" and it's cooeficient on one side of the equation

In the slope intercept form equation, we can see that the "y" variable is completely isolated on one side of the equation. Therefore,

Part III: Isolating "y" from it's cooeficient

The "y" variable in the slope intercept form has no cooeficient. Therefore, we need to isolate the cooeficient of "y" in our equation ( 3y = 3x + 15 ). This can be done by dividing 3 both sides or multiplying 1/3 both sides.

Part IV: Simplify the other side of the equation

Finally, simplify the other side to obtain our equation in slope intercept form.

Therefore, the equation in slope intercept form is y = x + 5.

The sequence 15, 18, 108/5 is a geometric sequence

The value of the 7th term is [tex]44\frac{2468}{3125}[/tex]

The sequence is given as:

15, 18, 108/5

The above sequence is a geometric sequence with the following parameters:

First term, a = 15

Common ratio = 18/15

The nth term of a geometric sequence is:

an = a * r^(n - 1)

So, the 7th term is:

a7 = a * r^6

This gives

a7 = 15 * (18/15)^6

Evaluate

[tex]a_7 = 44\frac{2468}{3125}[/tex]

Hence, the value of the 7th term is [tex]44\frac{2468}{3125}[/tex]

Answer:

580,000 people

Step-by-step explanation:

First, find out how many times the population will double. Divide the number of years by how long it takes for the population to double.

48÷24=2

The population will double 2 times.

Now figure out what the population will be after it doubles 2 times. Multiply the population by 2 a total of 2 times.

145,00022=580,000

That calculation could also be written with exponents:

145,000 x 2^2=580,000

After 48 years, the population will be 580,000 people.

Answer:

Step-by-step explanation:

The equation represents how much will be in the account after 2 years will be A = $6,500 + ($6,500 x 4 x 2)/100.

Let P be the principal, R be the rate of interest, and T be the time. Then the interest rate is given as,

I = (PRT)/100

6,500 dollars is placed in a savings account with an annual interest rate of 4%.

Then the amount after 2 years is calculated as,

A = P + I

A = P + PRT / 100

A = $6,500 + ($6,500 x 4 x 2)/100

Thus, the equation will be A = $6,500 + ($6,500 x 4 x 2)/100.

The y-value of the solution to the system of equations is 2.

We have given a system of equation

3x + 5y = 1

7x + 4y = −13

A system of equations is a collection of two or more equations with the same set of unknowns.

First we have to find the value of x.

3x + 5y - 5y = 1 - 5y

divide both sides of the equation by 3

3x/3 = 1/3 - 5y/3

x = 1/3 - 5/3y

Now plug that into the other equation,

7(1/3 - 5/3y) + 4y = -13

7/3 - 35/3y + 4y = -13

7/3 - 7 2/3y - 7/3 = -13 - 7/3

- 7 2/3y (-3/23) = -15 1/3 (-3/23)

y = 2

The answer is 2.
