Find the Area ( PLEASE LEAVE EXPLANATION)

Answers

Answer:

28 ft²

Step-by-step explanation:

Hello There!

To solve for the area of an irregular shape we want to split the irregular shape into regular shapes

For this irregular shape we would split it into a square with a side length of 2ft and a rectangle with a length of 6ft and a width of 4ft ( width was found subtracting total height of irregular figure (6ft) from height of square (2ft) 6ft - 2ft = 4ft so the width would be 4ft)

now we can easily solve for the area of each individual shape

area of square -

the area of a square can simply be found by raising the side length to the power of 2

so

[tex]a =2^2\\2^2=4\\a=4ft^2[/tex]

so we can conclude that the area of the square is 4ft^2

Now we want to find the area of the rectangle

the area of a rectangle is simply equal to the width times the length

so

[tex]a=6*4\\6*4=24\\\\a=24ft^2[/tex]

so we can conclude that the area of the rectangle is 24ft^2

Finally we add the two areas together

24 + 4 = 28

thus meaning the area of the irregular figure is 28 ft²

josie makes fruit punch by mixing fruit juice and lemonade in the ratio 1:4 she needs to make 40 litres of punch for a party
how much of each ingredient does she need

Answers

Answer:

the fruit juice and lemonade required 8 liters and 32 liters respectively

Step-by-step explanation:

The computation of each ingredient does she needed is given below:

Given that

There is liters of punch for a party is 40

And, the ratio of fruit juice to lemonade is 1:4

So,

The fruit juice is

= 40 × 1 ÷ 5

= 8 liters

And, for lemonade it is

= 40 × 4 ÷ 5

= 32 liters

hence, the fruit juice and lemonade required 8 liters and 32 liters respectively

Find cosθ, tanθ, and cscθ, where θ is the angle shown in the figure.
Give exact values, not decimal approximations.

Answers

Answer:

Cos(θ) = 7/√58 ; Tan(θ) = 3/7 ; Csc(θ) = √58/3

Step-by-step explanation:

First, let's solve for the hypotenuse by using the Pythagorean Theorem.

a² + b² = c²

⇒ 7² + 3² = c²

⇒ 49 + 9 = c²

⇒ 58 = c²

⇒ √58 = c

Now that we know the hypotenuse is √58, we can solve for the trig ratios.

Cos(θ) = adjacent/hypotenuse = 7/√58

Tan(θ) = opposite/adjacent = 3/7

Csc(θ) = hypotenuse/opposite = √58/3
