Answer:

r ≅ 10.2m

Step-by-step explanation:

Use formula: s = r * θ

s = arc length

r = radius

θ = angle in radians

8 = r * π/4

r = 32/π

r ≅ 10.2m

Answer:

y=10

Answer:

  (x, y) = (10, 6)

Step-by-step explanation:

Any of the usual methods work to solve this: elimination, substitution, graphing, matrix methods. For a "no-work" solution, I prefer a graphing calculator.

__

In the second equation, both x and y have coefficients of ±1, so substitution or elimination can be used with equal ease. Adding x to the second equation gives an expression for y that can be substituted in the first equation.

  y = x -4

  -3x +8(x -4) = 18

  -3x +8x -32 = 18 . . . eliminate parentheses

  5x = 50 . . . . . . . . . add 32, collect terms

  x = 10 . . . . . . . . . . .divide by 5

  y = 10 -4 = 6 . . . . . use the expression for y to find y

The solution is (x, y) = (10, 6).

Answer:

x=18

Step-by-step explanation:

you are correct all you do is add the four to 41, which is 44. you then divide 2.5 it equals 18

Answer:

18

Step-by-step explanation:

2.5x - 4 = 41

add 4 to both sides

2.5x = 45

divide both sides by 2.5

x = 18

I'm sorry i tried my best but x=0 is the only thing i got even though it's wrong

if there was a x for 2 it would be correct.

Answer:

Given: In trapezium PQRS, A and B are midpoints of diagonals PR and QS.

To Show: AB=1/2(SR-PQ).

Construction:draw midpoints C and D of SP and RQ respectively and join CA and BD

Proof: In triangle SPQ ,C and B are midpoints of SP and SQ

Therefore,by midpoint theorem

CB || PQ and 2CB= PQ ......1

In triangle QSR B and D are midpoints of QS and RQ

Therefore, by midpoint theorem

BD II SR and 2BD =SR..2

In triangle SPR C and A are midpoints of SP and RP

Therefore by midpoint theorem

CA = 1/2 SR .3

From 2

2 BD = SR =

BD =1/2 SR ........4

From 3 and 4

CA = BD ........,.......5

From 1 and 2

SR -PQ= 2 BD -2 CB -

SR-PQ = 2( BD-CB)

From 5

CA = BD ,

Therefore,

1/2(SR-PQ) =AB

AB= 1/2(SR-PQ)

Hence Showed

Answer:

y-intercept= (0, 0.4)

x-intercept = (0.3, 0)

Step-by-step explanation:

The intercept is where the line crosses the axis, and a coordinate is written out as, (x,y).

With this knowledge in mind, for the y-intercept, the x coordinate would be 0, and the y coordinate would be 0.4, which is where it crosses the y axis. This would make the y-intercept (0, 0.4).

For the x-intercept, the y coordinate would be 0, and the x coordinate would be where the line crosses the axis, making it 0.3. With these numbers and coordinates in mind, the coordinate for where the line intercept the x axis is (0.3, 0).

Answer: A. We will divide total seeds by the number of total rows.

300 seeds will be planted in each row.

Step-by-step explanation:

Given: Total seeds = 2700

Total rows = 9

If each row will have the same number of seeds.

Then,  the number of seeds will be planted in each row = (Total seeds) ÷ (Total rows)

= 2700÷9

= 300

Hence, 300 seeds will be planted in each row.

Answer:

increase by the percent

The fraction will decrease by 20%.

A fraction represents a part of a whole.

Let's assume the original fraction to be x/y.

If we increase the numerator by 20%, it becomes 1.2x.

If we increase the denominator by 50%, it becomes 1.5y.

So, the new fraction will be:

(1.2x) / (1.5y)

Simplifying this expression, we get:

(4x/5y)

The new fraction is (4/5) times the original fraction.

Therefore, the fraction will decrease by 20%.

Answer:

5^2 < 2^5

Step-by-step explanation:

2^5 = 2x2x2x2x2 = 32

5^2 =  5x5 = 25,

since 25 is less than 32, the comparison 5^2 < 2^5 is correct, or 25 < 32

The value of 2^5 is greater than 5^2.

An expression in maths a sentence with a minimum of two numbers or variables and at least one math operation.

Given that the same digits are used for the expression 2^5 and 5^2

2^5 = 32

5^2 = 25

Therefore, 2^5 > 5^2

Hence, The value of 2^5 is greater than 5^2.
