There are 35 squares shaded in a 50 square grid. What percentage of the grid is shaded?

There are 63 students are in the 2015 senior class, 5 students who are taking chemistry and biology, but not physics, and 18 students who are not taking science.

A Venn diagram is a graphic that employs circles to depict connections between objects or finite groups of objects.

Circles that overlap share characteristics, but circles that do not overlap do not.

In the Venn diagram the following data is observed;

Chemistry - 9                                          

Biology - 11                                            

Physics - 7                                            

Biology+Chemistry- 5

Biology+Physics - 4

Physics+Chemistry -6

Physics+Chemistry+Biology-3

None of the three - 18

Total -- 63      

We can clearly see from the table that the grand total of the table of data is the total number of pupils in the senior class. In other words, the total number of people is 63.

In addition, there are 7 students who are taking chemistry and biology but not physics.

The number of students who do not take science is equal to the number of students who do not take biology, chemistry, or physics, i.e. the 18 students outside the circle.

There are 63 students are in the 2015 senior class

There are 5 students who are taking chemistry and biology, but not physics.

There are 18 students who are not taking science.

Hence there are 63  students are in the 2015 senior class, 5 students who are taking chemistry and biology, but not physics, and 18 students who are not taking science.

Answer:

5.12$

Step-by-step explanation:

I know this because when your dealing with 20% think of it like 1/5.

Know 1/5 of 25.60 is 5.12 how I can calculate this is by timesing 5.12 by 5.

Here is what is would look like.

5.12 x 1=5.12$

5.12 x 2=10.24$

5.12 x 3=15.36$

5.12 x 4=20.48$

5.12 x 5=25.60$

And there's your answer(the last one by the way:))

If you want another example based upon 1/5 and 20% then say they were

30 cows and 30 horses 1/5 of them or 20% of them are sitting how many are sitting.

And since it is 1/5 what times 5 would=60 ?

It would be 12 so 20% of 60 is 12, do you understand what I am saying.

Hope this helps have a great day:)

The radius of the cylinder will be  [tex]r=2.25ft[/tex]

It is given that

[tex]Volume of the cylinder = 400 ft^{3}[/tex]

[tex]height of the cylinder= 25 ft^{3}[/tex]

Now we know that

[tex]Volume of the cylinder = \pi r^{2} h[/tex]

putting values in the formula

[tex]400= \pi \times r^{2} \times25[/tex]

[tex]r= \dfrac{4}{\sqrt{3.14} }[/tex]

[tex]r=2.25 ft[/tex]

Answer:

x>1

Step-by-step explanation:

In order to do this, we can take the inequality:

3+2x>5

now there are constants on both sides meaning we can combine them like the following:

3+2x>5

-3      -3

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

2x>2

Now we can simplify

2x/2>2/2

therefore, the answer is x>1

In order to graph this on a line you would need to put in a circle which is not filled in because x isn't equal to and greater than 1 so we put in a blank circle and since x is always going to be greater than 1, we would put a line that keeps going on.

You would put this line to the right of 1

The parking lot is 25 feet long and 22 feet wide

Step-by-step explanation:

Let's say the rectangle is [tex]x[/tex] feet long. It means it has to be [tex]x+3[/tex] feet wide.

Knowing it's area we can write an equation for the unknown:

Angel is 3 years younger than seven times Nancyś age and if Angel is 25 then Nancy is 4 years old.

Two or more expressions with an Equal sign is called as Equation.

Given that Angel is 3 years younger than seven times Nancyś age.

Let N be Nancy's age.

We know that Angel's age is 7N - 3.

We also know that Angel is 25.

So we can set up the equation: 7N - 3 = 25.

7N-3=25

Add 3 on both sides to isolate N

7N=28

Divide both sides by 7

N=4

Hence, if  Angel is 25 then Nancy is 4 years old.

Answer:

a = 3, b = 8

Step-by-step explanation:

Since x+3 is a factor, x=-3 is a root. =>  f(−3)=2(−3)3+a(−3)2−b(−3)+3=0

=>  9a+3b=51   =>  3a+b=17 — (1)

x-2 leaves a reminder of 15 =>  f(2)=2(2)3+a(2)2−b(2)+3=15

=>4a−2b=−4=>2a−b=−2 —- (2)

Adding (1) & (2),  5a=15=>a=3

Substituting the value of a in (1),  b=8

WY = 180

Step-by-step explanation:

the diagonals of an isosceles trapezoid are congruent , so

ZX = WY , that is

8y - 4 = 7y + 19 ( subtract 7y from both sides )

y - 4 = 19 ( add 4 to both sides )

y = 23

Then

WY = 7y + 19 = 7(23) + 19 = 161 + 19 = 180

12÷5= 2.5

ANSWER:2.5

The value of the 24th term is 16.

where

a = first term

d = common difference

n = number of terms

Therefore,

6 = a + 3d

8 = a + 7d

let's find a and d

2 = 4d

d = 2 / 4

d = 1 / 2

6 = a + 3 / 2

a = 6 - 3 /2

a = 4.5

Therefore, the 24th term can be found as follows;

24th term = 4.5 + 23(0.5)

24th term = 4.5 + 11.5

24th term = 16
