Answer:

108 participating schools

Step-by-step explanation:

Number of participating schools last year:  1.00(90 schools)

+20% more:  +0.20(90 schools)            (Increase over last year)

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

New count:  1.20(90 schools) = 108 participating schools

108 schools participated in the spelling bee this year.

Percentage is a ratio in the form of fraction of 100.

Percentage is defined by the "%" symbol.

According to the problem, In last year 90 schools participated in the state spelling bee.

This year 20% more schools are participating than last year.

So, Number of increased schools = 20% of 90

                                                        = ([tex]\frac{20}{100}[/tex]×90)

                                                        = 18

∴ Number of schools participated this year = 90+18 = 108

Answer:

150 degrees

Step-by-step explanation:

Let's start off by looking at what we are working with in this specific problem:

We can see that we are looking at 2 angles, angle L and angle M, that add up to a total of 180 degrees (aka a straight line)

Now that we know that, we also have to keep is mind that angle L + angle M = 180 degrees.

Now that we've got all of that out of the way, let's set up a simple algebraic equation:

angle L + angle M = 180

We also know that angle L is 30 degrees so let's add it into the equation we have just created:

30 + angle M = 180

We now know that 30 plus angle M (whatever it might be) is equal to 180 so in order to solve this problem we have to do some simple subtraction.

180 - 30 = angle M

Now we are left with:

150 degrees = angle M

Step-by-step explanation:

Given

There are 4 girls and 6 boys in a club

Probability of choosing 1 girl and 2 boys is

[tex]=\dfrac{\text{No of ways of choosing 1 girl and 2 boys }}{\text{No of ways of choosing 3 member out of 10 member}}[/tex]

No of ways of choosing 1 girl and 2 boys[tex]=^4C_1\times ^6C_2[/tex]

[tex]P=\dfrac{^4C_1\times ^6C_2}{^{10}C_3}[/tex]

[tex]P=\dfrac{4\times 15}{10\times 3\times 4}[/tex]

[tex]P=\dfrac{15}{30}=\frac{1}{2}[/tex]

i.e. [tex]50\%[/tex]

The probability that one girl and two boys will be chosen from the Spanish club is 50%.

Probability is used to determine the odds that an event would happen. If the event would happen with certainty, it would have a value of 1. If it is certain the event would not happen, it would have a value of 0.

The probability = number of ways of choosing 1 girl and two boys / number of ways of choosing 3 people

(4x15) / (10 x 3 x 4) = 15/30 = 1/2 = 50%

A straight line is an endless one-dimensional figure that has no width. It is a combination of endless points joined on both sides of a point. The x-intercept is (5/3, 0) and slope is 3.

A straight line is an endless one-dimensional figure that has no width. It is a combination of endless points joined on both sides of a point.

The standard form of a straight line is y=mx+c.

A slope of a line is the change in y coordinate with respect to the change in x coordinate

where m is the slope and c is the y intercept.

Here we have a straight line graph with y-intercept (0, -5)

and slope of m = 3.  

The x-intercept is (5/3, 0).

Hence the x-intercept is (5/3, 0) and slope is 3.

Answer:

0.014 cm .

Step-by-step explanation:

I am assuming that it is a closed cylinder whose total surface area.

Area = 2πrh + 2πr^2

Let the radius be r and the height h,  then we have the equations:

r + h = 34

2πrh + 2πr^2  = 2.992

From the first equation  h = 34 - r, so substituting for h:

2πr( 34 - r) + 2πr^2 = 2.992

2πr^2 + 68πr - 2πr^2 = 2.992

68πr = 2.992

r = 2.992 / 68π

r = 0.014

Answer:

29 feet in length, 5 feet in width and 12 feet in height

Step-by-step explanation:

We have that for the volume of a quadrangular prism is:

V = l * w * h

Ie length times width times height

In this case, the height is determined by the squares that you put in each corner, taking into account that a square has all the same sides, the height is 12 inches. h = 12

they tell us that the length is 24 inches more than the width, that is, l = 24 + w

replacing we have:

1740 = (24 + w) * w * 12

1740 = 12 * w ^ 2 + 288 * w

12 * w ^ 2 + 288 * w - 1740 = 0

if we calculate the root, we have w = 5 or w = -29

only works when w = 5

Thus:

l = 24 + 5

l = 29

which means that the dimensions are:

29 feet in length, 5 feet in width and 12 feet in height

29 feet in length, 5 feet in width and 12 feet in height

The volume of a quadrangular prism is:

[tex]V = l \times w \times h[/tex]

The length is 24 inches more than the width,

So l = 24 + w

Now

[tex]1740 = (24 + w) \times w \times 12\\\\1740 = 12 \times w ^ 2 + 288 \times w\\\\12 \times w ^ 2 + 288 \times w - 1740 = 0[/tex]

if we calculate the root, we have w = 5 or w = -29

only works when w = 5

So,

l = 24 + 5

l = 29

C = pi x d

d = r x 2

d = 5 x 2 = 10

C = pi x 10 = 10pi

Step 2) Find 1/4 of the circumference

10pi / 4 = 2.5pi = 7.85

Step 3) Add the two radii sides to the 1/4 circumference

7.85 + 5 + 5 = 17.85

C = 17.85 feet
