The track increased 400m:


1600 - 1200 = 400



Use the rule of 3:


1200 - 100%

400 - x


(400 * 100) / 1200 = x

40 000 / 1200 = x

33,33... = x


The increase was of 33% aproximately.




Hope it helped,


Happy homework/ study/ exam!

Beverly is painting a mural on a 1-square-meter section of a wall. She has completed a rectangular part of the mural that's is 5
yawa3891 [41]

Answer:

0.21 square meter

Step-by-step explanation:

Area of the section of wall = 1 square meter

Dimension of part of mural completed = \frac{1}{4} meter by \frac{5}{6} meter

Part of the mural completed = Area of the rectangular part of mural completed

But,

Area of a rectangle = length x width

So that,

Part of the mural completed = length x width

                                             = \frac{1}{4} x \frac{5}{6}

                                            = \frac{5}{24}

                                            = 0.2083

Part of the mural completed = 0.21 square meter

The part of the mural that has been completed by Beverly is 0.21 square meter.

Please help i suck at these

Answer:

1st Option;

j = 4.5

k = 2

Step-by-step explanation:

Let's solve for "j" first:

=> We know that by the definition of midpoint segment theorem we can say;

3j = 5j - 9

0 = 5j - 3j - 9

0 = 2j - 9

0 + 9 = 2j

9 = 2j

9/2 = j

4.5 = j

=> Now that we have j-value we use the same method to solve for k-value;

6k = k + 10

6k - k = 10

5k = 10

k = 10/5

k = 2

Therefore;

j = 4.5

k = 2

<u>So the first option would be correct!</u>

Hope this helps!

Answer me if you need a friend<br><br> Also 5x+25=35<br><br> x=
STALIN [3.7K]

Answer:

x = 2

Step-by-step explanation:

You are solving for the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operation, and =

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction.

First, subtract 25 from both sides of the equation:

5x + 25 (-25) = 35 (-25)

5x = 35 - 25

5x = 10

Isolate the variable, x. Divide 5 from both sides:

(5x)/5 = (10)/5

x = 10/5

x = 2

x = 2 is your answer.

Please help me with this<br> I'll mark you as brainliest
Rainbow [258]

Answer:

a) Just add 1 square on the right and 1 square on top for figure 4. Add 1 more in each place for figure 5.

b) Each stage adds a square above and a square to the right. The pattern never decreases. This trend is shown by figures 1, 2, and 3.

c) Figure 0 would be a single square. Simply follow the pattern in reverse. As the figure number decreases, squares are removed from the right and the top rather than added.
