What is the length or area of shaded part?

Ivanshal [37]

Answer:

29.7345 square units

Step-by-step explanation:

Area of the shaded part = Area of the rectangle - Area of the quarter circle

Area of the rectangle = Length × Width = 10 × 8 = 80 square units

Area of the quarter circle = $\frac{1}{4}$ × π × r² (r for radius) = 0.25 × π × 8² = 50.2655 square units (answer rounded up to four decimal places)

Area of the shaded part = 80 square units - 50.2655 square units = 29.7345 square units

Jacob trims trees and mows lawns during the summer months he earns 50$ per lawn and 120$ per tree he wants to purchase a car for

Artemon [7]

Answer:

at least 19

Step-by-step explanation:

Let t represent the number of trees Jacob needs to trim. He wants ...

50(45) +120t ≥ 4500

120t ≥ 2250 . . . . . . . . . subtract 2250

t ≥ 18.75

Jacob must trim at least 19 trees to earn at least $4500.

The area of a triangular flag is 132 square centimetres. Its altitude is 2 centimetres longer than twice its base. Find the leng

Anika [276]

Answer:

24 cm and 11 cm

Step-by-step explanation:

GIVEN: The area of a triangular flag is $132 \text{ cm}^2$ . Its altitude is $2\text{ cm}$ longer than twice its base.

TO FIND: lengths of the altitude and the base.

SOLUTION:

Let the altitude and the base of flag be $a$ and $b$

According to the question

$a=2+2b$

area of triangle $=\frac{1}{2}\times base \times alltitude=\frac{1}{2}a\times b$

$\implies \frac{1}{2}(2b+2)b=132 \Rightarrow 2b^2+2b-264$

Solving equation we get

$b=11$ then $a=24$

Hence the lengths of altitude and base of triangular flag is 24 cm and 11 cm respectively.

First person with a answer is marked as the Brainliest Answer

kramer

Answer:

h(x) = x/5

Step-by-step explanation:

We want to know the value of y to satisfy the given equation. So:

$6x+y=4x+11y\\\\y-11y=4x-6x\\\\-10y=-2x\\\\10y=2x\\\\y=\dfrac{2x}{10}\\\\\boxed{y=\dfrac{x}{5}}$

Hence, since h(x) returns the value of y we found before:

$\boxed{h(x) = \dfrac{x}{5}}$
