36-4.5x+36=102-7.5x-60

-4.5x=42-7.5x

7.5x-4.5x=42

Answer:

5000kg/m3

Step-by-step explanation:

Its easy to get the answer of a question from the unit.

So, it will be mass over metre cube.

Therefore, m=40kg x= (0. 2)^3 =0. 008m

40/0. 008 = 5000kg/m^3

24 Students

If 1/8 of the total is 3, then the total is 3 multiplied by 8 = 24

        Another way:

1/8= 12.5%

 12..5%_____3

     100%_____x

Cross multiplication

12.5x =3x100(300)

X=24

   12.5% of 24 = 3

There are 24 students in Ted's class.

Given that;

In Ted's class, students were asked to name their favourite sport.

And, Football was the response of 1/8 of them.

Let's assume the total number of students in the class is represented by "x".

According to the information given, 1/8 of the class said football, which means (1/8) × x students named football.

We also know that 3 students said football.

So, we can set up the equation:

(1/8) × x = 3

To solve for x, we can multiply both sides of the equation by 8:

x = 3 × 8

x = 24

Therefore, there are 24 students in Ted's class.

8:12 is 2/3 and so is 16:24, 2:3, and 20:30

Step-by-step explanation:

For example (includes simplified problem solving),

8 ÷ 4 = 2

12 ÷ 4 =3

You would want to divide the numerator and denominator by the greatest common factor (GCF)

The ratio 8:12 can be reduced to its lowest terms by dividing both terms by the GCF

Therefore 8:12 is 2:3

Answer:

  (-4, 8]

Step-by-step explanation:

The vertical extent of the graph is ...

  -4 < y ≤ 8

In interval notation, the range is (-4, 8].

Additional comment

There is a horizontal break (in the domain) at y=3, but no vertical break there. Hence the range is continuous through that region.

Answer:

$36

Step-by-step explanation:

The stock value of $40 increased by 20%.

Increased value

= 20% of $40

= (20/100) × $40

= $800/100

= $8

New stock value

= Initial value + increased value

= $40 + $8

= $48

Then, the value decreased by 25%.

Decreased value

= 25% of $48

= (25/100) × $48

= $1200/100

= $12

New stock value

= Initial value + decreased value

= $48 - $12

= $36

So, the resulting stock value is $36.

Answer:

The resulting value of the stock is $36.

Step-by-step explanation:

First, we need to find out what 20% of $40 is.

40 x 0.20 = 8

40 + 2 = $48

Therefore, the stock value, when increased, is $48.

Now, we need to see what 25% of $48 is.

48 x 0.25 = 12

48 - 12 = $36

Therefore, the resulting value of the stock is $36.

Answer:

x = -2

Step-by-step explanation:

7 - 48x - 42 = - 18x + 24 + 1

-35 - 48x = -18x + 25

-48x +18x = 25 =35

-30x = 60

x = -2

Answer:

-2

Step-by-step explanation:

7+6 (-8x-7)=3 (-6x+8)+1

7-48x-42= -18x+24+1

-48+18= 24+1-7+42

-30x=60 then divide the two sides with -30

Answer:

a^6

Step-by-step explanation:

When the same numbers, the power can be just added together

For example

n x n x n =n^3 right?

Ya cuz when they don't put the power, it means to the power of 1

Therefore

a x a^2 x a^3

Just means

a ^ (1+2+3)

=a^6

Answer: a^6

Step-by-step explanation:

Term does not have an exponent so it’s automatically 1. So, a^1xa^2xa^3.

Multiply terms and add their exponents. So, a^1+2+3z

Add all exponents and you get 6. So, a^6

Answer:

What is question? surface area of upright part of cylinder is approx 314 sq yd.  Surface area of entire cylinder is approx 471 sq yd, which isn't a choice.

Step-by-step explanation:

Assuming you're looking for surface area of cylinder (since answers are in sq units), you would need to find the area of the top and bottom circles, and the rectangle made by flattening out the upright part of cylinder.

Area of a circle is πr^2 so area of bottom is 25π and of both circles is 50π which equals approx 157.08 sq yd.

The rectangle formed from the upright part would have a width of 10 yds and a length equal to circumference of the circle.  Since C = πd, C is approx 31.4yd.  A = l x w so A = 31.4 x 10 or approx 314 sq yd.

Answer:

A.

Step-by-step explanation:

one x value cant go to two y values

Answer:

No....Not at all

You can select option A as the correct answer

Step-by-step explanation:

There can be two possibilities

From the definition of Function, We know, the value of a dependent variable corresponds to exactly one value of the independent variable

For possibility 1, For x = 5 and 9, y = 2 & for x = 5 and 7, y = 3

So this can't be a function

For possibility 2, For y = 3 and 2, x = 5

So this can't be a function
