The length of a rectangular field is 25 m more than its width. The perimeter of the field is 450 m. What is the actual width and length?

Answers

Answer 1

Answer:

length= 125

width= 100

Step-by-step explanation:

let width have a length of x m

therefore length= (x+25)m

perimeter=2(length +width)

p=2((x+25)+x)

p=4x+50

but we have perimeter to be 450,, we equate it to 4x+50 above,

450=4x+50

4x=400

x=100 m

length= 125

width= 100

C. The graph of f(x) is shifted 11 units up.
D. The graph of f(x) is shifted 11 units down.

Answers

Answer:

C. The graph of f(x) is shifted 11 units up.

Step-by-step explanation:

Given

[tex]g(x) = f(x) + 11[/tex]

Required

Interpret g(x)

When a function is shifted up in b units, the rule is:

[tex](x,y) \to (x,y+b)[/tex]

Replace b with 11

[tex](x,y) \to (x,y+11)[/tex]

Replace y with f(x)

[tex](x,f(x)) \to (x,f(x)+11)[/tex]

So, we have:

[tex]g(x) = f(x) + 11[/tex]

Hence; f(x) is shifted 11 units up.

Water is leaking out of an inverted conical tank at a rate of13400cubic centimeters per min at the same time that water is being pumped into the tank at a constant rate. The tank has height8meters and the diameter at the top is6meters. If the water level is rising at a rate of24centimeters per minute when the height of the water is5meters, find the rate at which water is being pumped into the tank in cubic centimeters per minute.

Answers

9514 1404 393

Answer:

  2,664,118.8 cm³/min

Step-by-step explanation:

The diameter at the water level of 5 m is (5/8)(6 m) = 3.75 m, so the area of the water surface is ...

  A = (π/4)d² = (π/4)(3.75 m)² ≈ 11.044662 m²

When rising at the rate of 24 cm/min, the volume is increasing at the rate ...

  (110,446.62 cm²)(24 cm/min = 2,650718.8 cm³/min

The input volume must be sufficient to accommodate this increase as well as the leakage. Then the input volume is ...

  2,650718.8 cm³/min + 13,400 cm³/min = 2,664,118.8 cm³/min

Which system of linear inequalities has the point (3, -2) in its solution set?

Answers

Answer:

None of the given system of linear inequalities

Step-by-step explanation:

Given

[tex](x,y) =(3,-2)[/tex]

Required

The line inequalities with the above solution

The first set of linear inequalities, we have:

[tex]y < -3[/tex]

[tex]y \ge \frac{2}{3}x - 4[/tex]

[tex]y < -3[/tex] implies that the values of y is -4,-5.....

While [tex](x,y) =(3,-2)[/tex] implies that y = -2

Hence, the first set is wrong

The second set of linear inequalities, we have:

[tex]y > - 2[/tex]

[tex]y \ge \frac{2}{3}x - 4[/tex]

[tex]y > - 2[/tex] implies that the values of y is -1,0.....

While [tex](x,y) =(3,-2)[/tex] implies that y = -2

Hence, the second set is wrong

The system of linear inequalities having the point (3, -2) in its solution set is y > -3; y ≥ 2/3x - 4.

What are systems of linear inequalities?

A system of linear inequalities is known to be a composition of  linear inequalities that can be found in the same variables.

The graph that is showing  y > -3; y ≥ 2/3x - 4

y ≥ 2/3x - 4

A telephone pole has a wire attached to its top that is anchored to the ground. The distance from the bottom of the pole to the anchor point is 49 feet less than the height of the pole. If the wire is to be 14 feet longer than the height of the pole, what is the height of the pole?

Answers

Answer:

  105 ft

Step-by-step explanation:

Let x represent the height of the pole. Then (x -49) is the distance from the pole to the anchor point, and (x+14) is the length of the wire from the top of the pole to the anchor point.

The Pythagorean theorem gives us the relation ...

  (x +14)² = x² +(x -49)²

  x² +28x +196 = x² +x² -98x +2401 . . . . eliminate parentheses

  x² -126x +2205 = 0 . . . . . . . . put in standard form

Answer: [tex]y^\frac{1}{8}[/tex]

Step-by-step explanation:

Ok so when taking roots the number in the little corner at the left of the radical sign (if there is one) is the root you take. It could be the 4th root, 6th root, or the x root. You don't have to use the radical sign though, you can use an exponent to write it. All you have to do is take the reciprocal of the number to find what to write for the exponent. So for those examples it would be [tex]\frac{1}{4}, \frac{1}{6} ,\frac{1}{x}[/tex]. The number in the top left of the radical sign is 8 so the answer would be [tex]y^\frac{1}{8}[/tex]

The perimeter of a collage basketball court is 96 meters and the length is 14 meters more than the width. What are the dimensions? HELP MEEEEE

Answers

Mark Brainliest please

Perimeter of a rectangle,

Pr = 2L+ 2W

L = (W + 14)

Pr = 2(W+14) + 2W

Pr= 2W + 28 +2W

Pr =96 = 4W + 28

Pr = (96 — 28) = 4W

Pr = 68 = 4W

W = 68/4 = 17m, L= 17+14 = 31m

Check:

17m+17m+31m+31m= 96m

Answer:

width = 17 m ; length = 31 m

Step-by-step explanation:

w = width

l = length

perimeter of a rectangle = (length + width) * 2

l = 14 + w

(14 + w + w) * 2 = 96

(14 + 2w) * 2 = 96

28 + 4w = 96

4w = 68

w = 17 m

on monday, sammy the storekeeper decided the increase the price of avocados by 20%. on tuesday he increases this price by another 25%. what percent of the original avocados after both increases? on Wednesday, sammy decides to return the avocados to their original price. by what percent must he decrease the tuesday price?

Answers

Answer:

I think 55%

Step-by-step explanation:

Answer:

Increases = 50%On Wednesday, sammy must decrease 50% to return to original price

Step-by-step explanation:

price on monday go to: 100% + 20% = 120% = 1,2 x first price

price on tuesday go to: 125% of 120% = 1,25 x 1,2 = 1,5 x first price

Increases = 50%

on Wednesday, sammy must decrease 50% (of price after second increases) to return to original price

For example for understanding:

If original price is $100

firs increase: new price: $100 + $20 = $120

second increase: new new price: $120 + $30 = $150

final price - original price = $150 - $100 = $50

And  icreases/original = $50/$100 =0,5 = 50%

For return to orignial price, sammy must have to reduce 50% the price of avocados in wednesday
