Answer and explanation:

If Magdala is trying to divide 2.12 by 4 then she would definitely need to change the place value of the dividend(2.12) and the divisor(4). In other words, both numbers need to be whole numbers.

To make 2.12 a whole number, we shift the decimal point two places to the right of the decimal point to get 212. We do same for 4 to get 400, since both numbers have to have their place values adjusted equally.

We divide 212 by 400 to get 0.53

Therefore 2.12 divided by 4= 0.53

Answer:

x = 3

y = 2

Step-by-step explanation:

5x - 3 = 6y

5x + 3 = 9y

y = 5/6 x - 1/2

5x + 3 = 15/2 x - 9/2

-5/2 x + 15/2 = 0

-5/2 (x - 3) = 0

x = 3

Answer:

x = 3

y = 2

Step-by-step explanation:

because it's a rectangle, opposite sides are equal

AD = BC

AB = DC

so we can use their measures to create a system of equations:

5x + 3 = 9y

5x - 3 = 6y

if we multiply the first equation by -1 we can eliminate the x-values:

-(5x + 3 = 9y)

 -5x - 3 = -9y

+ 5x - 3 = 6y

        -6 = -3y

         y = 2

If y = 2 then BC = 12 and we can set up this equation:

12 = 5x - 3

15 = 5x

3 = x

D) the time spend reading book and the number of pages remaining to be read in the book.

Step-by-step explanation:

First, we need to put this standard form into slope-intercept form

To do this you need to move the "y" to all by itself

-25x+25x-20y=100-25x

-20y=100-25x

y=5/4x-5

Answer:

y=5/4x-5

The slope is-5/4 and the -intercept is (0,5)

Locating the y-intercept on a graph requires knowing the value of y at x=0. This is where the graph intersects the y-axis.

25x−20y=100

20y = 100 + 25x

20y=100+25x

y = [tex]5 + \frac{5}{4}[/tex]

She concluded that the slope is   [tex]\frac{5}{4}[/tex]

​and the y-intercept is (0,5).

y = mx + b where m is the slope and b is the y-intercept. So, the slope is 5/4 and the y-intercept is -5.

The slope is-5/4 and the -intercept is (0,5)

There are 30 two-point questions and 20 five-point questions.

What is equation?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

According to questions, Brandon took a 50-question exam worth a total of 160 points.

There were x two-point questions and y five-point questions.

So,[tex]y=50-x[/tex]

Now, according to question, we will get the following equations

[tex]2x+5(50-x)=160[/tex]

⇒[tex]2x+250-5x=160[/tex]

⇒[tex]-3x=-90[/tex]

The final cost of meal is $171.35

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given:

price of food = $137 . 61

Tip = 18%

tax = 6.5%

Now, price after giving tip

=137.61 x 0.18

= 24.7698

and, after tax

=137.61 x 0.065

=8.94465

Hence, final cost of meal = 137.61 + 24.7698 + 8.94465 = $171.35

Answer:

  UV is not the midline. (The midline length is 4.5.)

Step-by-step explanation:

The trapezoid midline is the average of the lengths of the bases. Here, the midline length would be ...

  (7 ft +2 ft)/2 = (9 ft)/2 = 4.5 ft

The line length shown is 3.5 ft, so the segment shown is not the midline.

Step-by-step explanation:

From the original question, we can rewrite this as:

An airplane company is determining the difference in selling price if rows of first-class seats are added to a new design. The total selling price for one new row is f(r) = 4,000r. Each row in first class eliminates a pair of rows of economy seats. The total price for each pair of removed rows is e(r) = 1,800r. Which is d(r), the profit or loss for adding r rows of first class seats?

f(r) = 4000r

e(r) = 1800r

d(r) = ? (profit or loss)

Assuming we had added a row of first class seats,

+ f(r) = 4000r

But we had to remove a pair or rows from the economy seats,

- e(r) = 1800r

Translating these into one equation:

d(r) = f(r) - e(r) = 4000r - 1800r = 2200r

Therefore, OPTION A.) d(r) = 2200r

The value of d(r) will be 2200r. The correct option is A.

Answer and Step-by-step explanation:

Since we know that this figure is a square pyramid, the base is a square. And the area of a square is its side multiplied by its side, which the sides would equal the same (since it is a square).

So, we square 625 to find One side of the square.

[tex]\sqrt{625} = 25[/tex]

We get 25 as the side.

The volume equation for a square pyramid is:

[tex]V = a^{2}( \frac{h}{3} )[/tex]

Where a is the side length of the base, and h is the height.

Plug in the values.

[tex]V = (25)^{2} (\frac{30}{3} )\\\\V = 625(10)\\\\V = 6250[/tex]

The volume of the square pyramid is 6250 cubic meters.
