When 40​% of a number is added to the​ number, the result is 168.
What is the number?

There are 20.65% of the total number of students increased on the honor roll.

Percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100.

Here, For last year

         Total boys for honor roll = 100

          total girls for honor roll = 84

          total students for honor roll = 100+84 = 184

For present year,

      Boys for honor roll = 100 + 100X0.17 = 117

      Girls for honor roll = 84 + 84X0.25 = 105

      Total students = 117 + 105 = 222

Increment in total students = 222 - 184 = 38

% increment in total student = 38 X 100 / 184

                                                = 0.2065 X 100

                                                = 20.65 %

Thus, there are 20.65% of the total number of students increased on the honor roll.

Answer:

25

Step-by-step explanation:

5(x+6)−(5−x)−6x

Remember PEMDAS

P – Parentheses

E – Exponents

M – Multiplication

/D – Division  (whichever comes first from left to right)

A – Addition

/S – Subtraction (whichever comes first from left to right)

First, let's distribute the left side:

5 * x = 5x

5 * 6 = 30

5x + 30

Now, lets distribute the right side

-(5 - x) = -1(5 - x)

-1 * 5 = -5

-1 * -x = x  ( - * - = +)

x - 5

Now we have:

5x + 30 + x - 5 - 6x

Let's combine like terms.

5x, -6x, and x are like terms. 5x + x =  6x - 6x = 0

30 and -5 are like terms. 30 - 5 = 25

25

Since we can't simplify this any further, that is our answer.

Answer:

(0,2)

Step-by-step explanation:

Since x is by itself plug that in for the second equations x

X+8y =16

2y-4+8y=16 solve for y

10y-4=16

10y=20

Y=2

Plug 2 for y into the first equation

X= 2y-4

X=2*2-4

X=4-4

X=0

Those are your points, (0, 2)

Answer:

A)53.25

B)35.5

Step-by-step explanation:

86-15=71

add his times and hers

3+1=4

71/4=17.75

17.75*3=53.25

53.25-17.75=35.5

Answer:

57 degrees

Step-by-step explanation

Answer:

x = 57

Step-by-step explanation:

So we know all triangles add up to 180 degrees. And that supplementary angles add up to 180 degrees.

So, we can do that missing angle + 138 = 180

180 - 138 = 42

180 - 42 - 81 = x = 57

Hey buddy, here is your answer. Hope it helps you.

Step-by-step explanation:

1. 0.008

2. Square root of 64 is 8 and cube root of 64 is 4. The difference is 4.

3. Area=100 sq.cm. The side is 10 cm. so the perimeter is 4 x Side= 4x10=40 cm.

4. the two square roots of 25 are 5 and 5. Cuz 5 and 5 gives 25.

Step-by-step explanation:

Morgan has $60. That is his spending limit.

He buys a pair of jeans for $25.

Each T-shirt is $5

We don't know how many t-shirts he can buy, so we can represent it with a variable, x

so,

[tex]25 + 5x \leq 60\\5x \leq 60 - 25\\5x \leq 35\\x \leq \frac{35}{5} \\x\leq 7[/tex]

Answer:

20mi[tex]1^{2}[/tex]

Step-by-step explanation:

Well, I'm guessing that the 1mi by 1mi is the two square sides and 5 mi is the length of the rectangular part

So with that information, the two surface areas of the squares would be 1mi[tex]1^{2}[/tex]+1mi[tex]1^{2}[/tex] is 2mi[tex]1^{2}[/tex]

And then the four rectangular sides would be 5mi[tex]1^{2}[/tex] *4 = 20mi[tex]1^{2}[/tex]

in conclusion

Step-by-step explanation:

The mean is just the multiplication of [tex]n[/tex] and [tex]p[/tex] so [tex]60 * 0.3[/tex] = [tex]18[/tex]

Variance is [tex](1 - p) * n * p[/tex] so [tex]0.7 * 60 * 0.3 = 12.6[/tex]

So the variance is [tex]12.6[/tex]

The standard deviation is just the root of the variance so: [tex]\sqrt{12.6}[/tex] = [tex]3.55[/tex] rounded to the nearest hundredth. :D

Given:

Alan salary P (in dollars) when he works h hours is represented by the equation

[tex]P=12.50h[/tex]

To find:

The earning per hour.

Solution:

We have,

[tex]P=12.50h[/tex]

Here, P is total salary and h is number of hours he works.

[tex]\text{Earning per hour}= \dfrac{\text{Total salary}}{\text{Number of hours}}[/tex]

[tex]\text{Earning per hour}= \dfrac{12.50h}{h}[/tex]

[tex]\text{Earning per hour}=12.50[/tex]

Therefore, the earning per hour is $12.50.

768

Step-by-step explanation:

First multiply by two

Then multiply by four

Answer: 768

Step-by-step explanation:

Because it’s 50% of 25% of 96, you may know that 100 divided by 25=4 So it’s kinda the same concept with this, you first can do 96*4=384, then do 384*2=768. You would multiply by 2 because 100/2=50, and what not. I know this is the same thing as the other person but whatevvvv

Answer:

it is the right triangle

Step-by-step explanation:

A set of three integers that can be the length of the sides of a right triangles

Answer:

Yes

Step-by-step explanation:

This is what I think:

This is because the hypotenuse of the triangle is 45m.

27 ^2 + 36 ^2 = 2025

2025 SQAURE ROOT IS 45.

So the square root of the two other measurements squared must be equal to the hypotenuse.

Answer:

Step-by-step explanation:

The sum of two interior angles in a triangle is equal to an

exterior angle that's complementary to the third interior angle

60 + 4 + 8x = 8 + 16x add like terms

8x + 64 = 16x + 8

64 - 8 = 16x - 8x

56 = 8x divide both sides by 8

Answer:

128+32=160

Step-by-step explanation:

Since a rectangle is 8 x 4=32, and there are 4 rectangles, the surface area of the four rectangles is 32 x 4=128

There are also two squares whose area is 4 x 4=16

16 x 2=32
