Answer:

Step-by-step explanation:

=======================================================

Explanation:

x = total number of students surveyed

According to the table, 0.075 of the students (aka 7.5%) have blond hair and blue eyes. This means 0.075x is the number of blond hair blue eye people.

Also, 0.125x is the number of brown hair blue eye people for similar reasoning as the previous paragraph.

We're told that "There are 4 more students with brown hair and blue eyes than blond hair and blue eyes"

So,

(BrownHair_BlueEyes) = (BlondHair_BlueEyes) + 4

0.125x = (0.075x) + 4

0.125x-0.075x = 4

0.05x = 4

x = 4/0.05

x = 80

There are 80 students surveyed.

Of those eighty students,  0.075x = 0.075*80 = 6 have blond hair and blue eyes; while 0.125x = 0.125*80 = 10 have brown hair and blue eyes. Notice how this is four more than the blond person count with blue eyes. This confirms we have the correct sample size.

The last step is to calculate how many of the students have black hair based on the sample size we just found.

The table shows 25% = 0.250 of the students have black hair, so 0.25x = 0.25*80 = 20 students have black hair

Let the tens digit of the number be x .

ones digit = ( 14 - x ) ( since the sum of the 2 digits is 14 )

Two - Digit number = 10 ( tens digit ) + ones digit

Required number ,

Reversed number ,

Given ,

Reversed number - Required number = 36

✯ 140 - 9x - ( 9x + 14 ) = 36

✯ 140 - 9x - 9x - 14 = 36

✯ 126 - 18x = 36

✯ 126 - 36 = 18x

✯ 18x = 90

✯ x = 5

♧ Thus , Required number is 10 × 5 + 9 = 59

Given -

i.e, if two numbers are x and y then, x + y = 14

i.e, if 10y + x then 10y + x = 10x + y + 36.

To find -

Concept -

If a, b and c are real number (and if a and b both are not equal to 0) then ax+by=c is called a linear equation in two variables (The two variables are x and y)

The numbers a and b are called the coefficient of the equation ax+by=c. The number r is called the constant of the equation ax+by = c

PS - first we will construct two linear equations and then we'll find the number.

Solution -

Let, x + y = 14

➜ y = 14 - x ----(i)

and we'll solve 10y + x = 10x + y + 36 further,

➜ 10y + x = 10x + y + 36

➜ 10y - y = 10x - x + 36

➜ 9y = 9x + 36

➜ 9x - 9y = -36

➜ 9(x - y) = -36

➜ x - y = -4 ----(ii)

Substituting the value of y (in equation (i)) in equation (ii),

➜ x - (14 - x) = -4

➜ x - 14 + x = -4

➜ 2x = -4 + 14

➜ 2x = 10

➜ x = 10/2

➜ x = 5

Now to find the value of y we will substitute the value of x in equation (i),

➜ y = 14 - 5

➜ y = 9

Therefore, the number is {10(5)+9,i.e,} 59.

Answer:

Answer:

4GB

Step-by-step explanation:

cause if you think about it if they already have used 2GB in half the month then its' reasonable to think it would be 4GB. simple math

Pattern A = 1, 4, 7, 10, 13

Pattern B = 1, 5, 9, 13, 17

Each term is increases at a faster rate in pattern B; the difference between terms increases by one per step. In pattern A, 1 jumps to 4, while in pattern B, 1 jumps to 5. There is a difference of one. But when in pattern A, 4 jumps to 7, in pattern B, 5 jumps to 9. The is a difference of two between these two terms even though they are on the same "jump." This difference increases by one per "jump." (Jump is not the official word for this but I'm assuming this isn't a sequence problem.)

Answer:

1. 83 square inches

2. 7.065 square centimeters

Step-by-step explanation:

Hey there!

In order to find the area of the shaded region of the rectangle, you need to first find the area of the whole shape

The dimensions are 10 and 16 and if you multiply them together, you get 160

This means that the area of the whole shape is 160

Now they are asking for the area of the shaded shape, so we need to find the area of the white rectangle, and then subtract that area from 160

The dimensions for the white rectangle is 11 and 7

This means that the area of the white rectangle is 77

Now what we need to do is subtract 77 from 160

160-77=83

So the area of the shaded region is 83 square inches

Now to get to the second question

We need to find the area of the quarter circle

In order to find this, we need to first find the area of the whole circle, then divide that by 2

They gave us the radius already which makes it a lot easier (the radiues is 3)

All we need to do is input 3 into the formula for the area of a circle

[tex]\pi r^2[/tex]

In this case, since they are telling us to use 3.14 as pi, the equation would look like this:

[tex]3.14*3^2[/tex]

This can be simplified to [tex]3.14*9[/tex] which is equal to 28.26

So this is the area of the whole circle

But the question is asking for the area of a quarter of that circle

So what we need to do is divide 28.26 by 4 which is 7.065

So the area of the quarter circle is 7.065 square centimeters

Answer:

  C)  18

Step-by-step explanation:

Let x represent the largest of the five consecutive integers. Then (x -4) is the smallest, and the sum of the five of them is ...

  sum = 5((x +(x -4))/2 = 5x -10

That sum is 46 less than 9 times the smallest.

__

This relation can be written as ...

  5x -10 = 9(x -4) -46

  72 = 4x . . . . . . . . . . . . add 82-5x and simplify

  18 = x . . . . . . . . . divide by 4

The largest of the consecutive integers is 18.

_____

Additional comment

Here, we have used the variable to represent what the problem is asking for--the largest of the integers. Often, in consecutive integer problems, it is convenient to let a variable represent the middle (or average) value of the consecutive integers. If we do that here, then sum of the 5 integers would be 5x, and the relation to find x would be ...

  5x +46 = 9(x -2)

This resolves to 64=4x ⇒ x=16, so the largest integer is x+2=18. The number of steps is about the same, but the sum is easier to find, and there aren't as many constant terms to play with in solving for x.

Step-by-step explanation:

Pythagoras's rule:  [tex]a^2 + b^2 = c^2[/tex]  becomes  [tex]x^2 + 10^2 = y^2[/tex]

If we try: 3) x = 4 y = [tex]29\sqrt{2}[/tex]...

[tex]\sqrt{(29\sqrt{2})^2 - 4^4} = 7\sqrt{34} \neq 10[/tex]

If we try: 4) x = 16 y = 116...

[tex]\sqrt{116^2 - 16^2} = 20\sqrt{3} \neq 10[/tex]

If we try: 2) x = 16 y = 29...

[tex]\sqrt{29^2 - 16^2} = 3\sqrt{65} \neq 10[/tex]

If we try: 1) x = 4 y = [tex]2\sqrt{29}[/tex]...

[tex]\sqrt{(2\sqrt{29})^2 - 4^2} = 10[/tex]

The point that is not on the graph of the linear equation y = 10 + x is given by:

C. (8, 2)

It is given by:

y = 10 + x.

Hence, all the points on the graph have the following coordinates:

(x, x + 10).

Option C does not follow this format, hence it is not on the graph.

Answer:

  325 adult tickets

Step-by-step explanation:

This "sum and difference" problem can be solved by assigning a single variable to the quantity you want to know. Let 'a' represent the number of adult tickets sold. Then (a-60) is the number of student tickets sold, and the total number sold is ...

  a +(a -60) = 590

  2a = 590 +60

  a = 650/2 = 325

There were 325 adult tickets sold.

__

Check

325-60 = 265 student tickets were sold, for a total of 325+265 = 590.

Answer:

[B] 68

Step-by-step explanation:

Given:

the figure in the picture

Solution:

Q - 124 + 56 =180

Since,  r is also 56 degrees that means S is 68 degrees because the sum of each angle has to add up to 180 degrees.

Step by step solving below:

Q = 180 - 124

Q = 56

56 (m∠Q) + 56 (m∠ R) = 112

S = 180 - 112

S = 68

Thus, the answer is [B] 68 which also means m∠ 68

Kavinsky

Answer:

mS = 68 (B)

Step-by-step explanation:

First, we are given mR, which is 56.

Next, we can figure out mQ by subtracting 124 from 180 (because it's a straight line) :: 180 - 124 = 56, SO, mQ = 56

Now, we know that the sum of all the interior angles is 180, so we'll subtract mR and mQ from that....

180 - (mR + mQ) >> 180 - (56 + 56) >> 180 - 112 = 68

therefore, mS = 68
