Step-by-step explanation:

so in order to find the surface are of square and rectangle we have this formula square =a^2

Some of the rectangles are 11*5 = 55

And for the squares they are 2*5=10

But we have 2 rectangle with 2*11=22

Basically just add them up and the answer is 174m^2

174.

the L of the main rec is 11x14 the side boxes both have an area of 10. add all up and you get 174

can someone explain how to do this, I don't want the answer?

The table is filled out by following these steps:

Step 1) Pick any number you want for x. Usually small values work such as x = 0, but you can choose anything you want. Be sure it fits within the window of the graph.Step 2) Replace x with that number you picked. If you picked x = 0, then y = (1/3)x becomes y = (1/3)*0 = 0. Meaning x = 0 leads to y = 0. The point (0,0) is on the graph.Step 3) Go back to step 1 and repeat the process with other x values. I recommend picking multiples of 3 so you can avoid fractional values of y.

Follow those steps listed above so you can fill out the table. Each row of the table generates a different (x,y) point on the graph. Then draw a line or curve through the points. In this case, it's a straight line.

This straight line has a slope of 1/3 because y = (1/3)x is in slope-intercept form y = mx+b where,

m = 1/3 = slopeb = 0 = y intercept

A slope of 1/3 means "go up 1, over to the right 3" when hopping from point to point along the line.

The unit rate and slope are the same thing when it comes to linear equations.

You have the slope already, you need to find the unit rate with the slope, you just have to put 1/3 in the graph and use rise/run

Vowels include AEIOU, so in the first box there is 2 vowel out of the 5 letters so 2/5 probability for the first box. Box 2 includes 2,4,6,8 as the even numbers out of the 9 numbers so 4/9
If you were solving the probability for each box individually that would be your answer
However if you are doing statistics and need to do it in a certain order you multiply the fractions
2/5 x 4/9 = 8/45
(.17777)
This leaves you with a 17% (8/45) chance of picking a vowel then an even number.

the probability of getting a vowel is 2/5 because a vowel is A E I O U and sometimes Y, and there’s 2 vowels out of 5 letters

Mrs. Hanger is painting the following picture of an H to hang in the entryway of her home. She has made the following scale drawing as her model. The scale used on the drawing is 1:6. On the scale drawing, H is centered on the page and is inches from the top, bottom, and sides of the drawing.

As you can see, the "H" is going to be painted brick red in the center of a rectangular beige background. This means the distance from the "H" to the top of the picture will be the same as the distance from the "H" to the bottom of the picture. Similarly, the distance from the "H" to the left side of the picture will be the same as the distance from the "H" to the right side of the picture.

Find the volume of the cone. Round to two decimal places

Answers

Answer:

564.44

11*7 squared

Answer:

V = 564.15 ft^3

Step-by-step explanation:

The formula for the volume of a cone of base radius r and height h is

V = (1/3)(pi)(r^2)(h). Here, r = 7 ft and h = 11 ft, and so the volume of this particular cone is

V = (1/3)(3.14)(7 ft)^2*(11 ft), or V = 564.15 ft^3

11x+2=5x+10+58

Answers

x = 11

Step-by-step explanation:

=> 11x + 2 = 5x + 10 + 58

=> x = 66/6

=> x = 11

We are asked to solve the equation [tex]\large\pmb{11x+2=5x+10+58}[/tex].

[tex]\triangle~\fbox{\bf{KEY:}}[/tex]

The goal is to get x all by itself.

So here's how we solve the equation...

///\\\///\\\///\\\///\\\///\\\///\\\///\\\///\\\///\\\///\\\\///\\\///\\\///\\\///\\\///\\\///\\\///\\\

Notice that we can add 10 and 58 right off the bat:

[tex]\large\pmb{11x+2=5x+68}[/tex]

Now we subtract 2 from both sides of the equal sign:

[tex]\large\pmb{11x=5x+66}[/tex]

Now we subtract 5x from both sides of the equal sign:

[tex]\large\pmb{6x=66}[/tex]

Divide both sides by 6:

[tex]\large\pmb{11}[/tex]

That's the value of x.

A book store is hosting a special night in which families can enjoy a story and craft time. Tickets to the
event must be purchased ahead of time and are $1.50 for children and $2.50 for adults. So far, 45
children's tickets have been sold, which is 60% of the total tickets sold. How many tickets have been
sold so far? Show your calculations or explain how you got your answer.

Answers

Answer:

75 total tickets

Step-by-step explanation:

METHOD 1:

We know that 45 children's tickets have been sold, being 60% of the total tickets having been sold.

So, basically, we solve for x:

We have, 60% × x = 45

or, 60/100 × x = 45

Multiplying both sides by 100 and dividing both sides by 60,

we have x = 45 × 100/60

x = 75

If using calculator, enter 45x100/60, which will give you the answer.

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

METHOD 2:

Division is the opposite of multiplication

Start with the formula to calculate the percentage of total

y=value÷ percentage/100

Substitute values in the equation

y=45÷60/100

Simplify and solve

y=45÷0.6

y=75

Both methods give you 75, therefore 75 tickets have been sold

So your supposed to do 1.50/1 x 60% which is 90
