The field width of thestadium is 40m lessthan its length. The total length of the rectangular boundary of the open space in canopy is 420m. Frame a suitable
equation for the given situation and also find the length and width of the field in the stadium.

Answers

Answer 1

Answer:

I may have misubderstood the question, so review carefully.

width = 380 m

length is 420 m

Step-by-step explanation:

Let w and l stand for the width and length of the stadium.

We are told that w = l - 40 m

We also learn that l = 420 m

w = l - 40 m

w = (420 m) - 40 m

width = 380 m

length is 420 m

Answers

Step-by-step explanation:

x + 15 +2x + 66 = 180

3x + 81 = 180

3x = 99

x = 99/3 = 33

plz mark my answer as brainlist plzzzz.

hope this will be helpful to you.

Answer:

The angles are 66, 66, and 48 degrees

The triangle is isosceles because 2 angles are equal, thus two leg lengths are equal

Step-by-step explanation:

the sum of all three angles in a triangle = 180 degrees

66 + 2x + (x+15) = 180

simplify

66 +3x + 15 = 180

reduce

81 + 3x = 180

subtract 81 from each side

81 - 81 + 3x = 180 - 81

3x = 99

divide both sides by 3

3x/3 = 99/3

x = 33

The cheerleading squad at Kensington High School had 18 members with the old coach. Now, with the new coach, there are 50% more members on the squad, how many members are on the squad now

Answers

Answer:

27 members

Step-by-step explanation:

So we have 18 members and we see a 50% increase in members.

So:

Now the squad is 150% of 18

We can set up a percent proportion

x/150=18/100

To solve, we do:

(150*18)/100 = x

27 = x

There is an easier way to do this with benchmark fractions.

We find 50% of 18 which is 9

And since it's a 50% increase, we add 9 to 18 and get 27

Given: - 4x/7 > 10. Choose the solution set. {x | x < - } {x | x > - } {x | x > - } {x | x < - }

Answers

Answer:

{x | x < - 35 / 2}

Step-by-step explanation:

-4x / 7 > 10

Multiply both sides by 7

-4x /7 * 7 > 10 * 7

-4x > 70

Divide both sides by - 4

-4x / - 4 > 70 / - 4

x < - 35 / 2 (inequality sign changes)

What are the factors of the function represented by this graph?

C. (x + 4) and (x − 8)
D. (x + 4) and (x + 8)

Answers

The factors of the function represented by the graph are (x + 4) and (x - 8)

How to determine the factors of the function represented by the graph?

From the question, we have the following parameters that can be used in our computation:

The graph

From the graph, we can see that:

The graph intersects with the x-axis at x = -4 and x = 8

So, we have

x = -4 and x = 8

Set the equations to 0

So, we have

x + 4 = 0 and x - 8 = 0

This means that the factors of the function represented by the graph are (x + 4) and (x - 8)

Look at the angles and the little tallies to match up the triangle. Or use the given: triangle DEF is similar to triangle KJI. If it’s like that in a given you know the order is equal. (D and K are similar, E and J, and F and I)
So if line FD is the 3rd and 1st letters of the first triangle, then it has to be equal to the 3rd and 1st letter of the 2nd triangle.
IK

Another way to do this is that when you find FD on the triangle you can set that the line has 3 tally marks. Then look at the other triangle and find a line in which there are 3 tally marks.
The order in which you put the letters does not matter. IK and KI should both be considered correct
