If the length of a rectangle is 5 m more than its width find the values of length and width if the area of a rectangle is 500 m²

astra-53 [7]

Answer:

Length of the rectangle =25

width of the rectangle = 20

Step-by-step explanation:

Step(i):-

Let 'x' be the width of the rectangle

Given that the length of a rectangle is 5 m more than its width

Given that Area of the rectangle = 500m²

length of a rectangle = x +5

width of a rectangle = x

Step(ii):-

Area of the rectangle = length × width

500 = x ( x+5)

x² + 5 x = 500

⇒ x² + 5 x - 500 =0

⇒ x² +25x - 20 x - 500 =0

⇒ x( x+25) -20(x+25) =0

⇒ (x-20)(x+25) =0

⇒ x =20 and x=-25

we can choose x =20

Step(iii):-

Length of the rectangle = x +5 = 20 +5 =25

width of the rectangle = 20

Final answer:-

Length of the rectangle =25

width of the rectangle = 20

The ratio of the number of beads Karen had to the number of beads Patricia had was 2:5 .After Patricia bought another 75 beads,t

Andre45 [30]

We can bring the ratios to a similar form, because 2:5 is the same as 4:10 (we can mupltiply rations by the same number)

so one ratio is 4:10 and the other is 4:15 and the difference is is 75 beads

in this ratio, we can see each number corresponding to a "unit" of beads: that means that what changed is that Patricia now has 5 more such groups (15-10=5), and since she has 75 beads more each unit must be 75/5=15.

so afterwards (and before) Karen had 4 such units, that is 60, and Patricia before had 10 such units, that is 150.

Bob spent $78,475 on supplies to build a house. The house is 2,150 square

solong [7]

Im pretty sure it’s $36.50 because you divide 78,475 by 2,150

Please help. Solve the triangle. Round ans to the nearest tenth.

White raven [17]

Answer:

C = 21°
a = 13.3
c = 5.4

Step-by-step explanation:

The third angle can be found from the sum of angles in a triangle.

A + B + C = 180°

C = 180° -62° -97°

C = 21°

The remaining side lengths can be found using the Law of Sines.

a/sin(A) = b/sin(B)

a = sin(62°)(15/sin(97°)) ≈ 13.34

Similarly, ...

c/sin(C) = b/sin(B)

c = sin(21°)(15/sin(97°)) ≈ 5.42

The remaining side lengths are approximately ...

a ≈ 13.3

c ≈ 5.4
