Solve perimeter of both rectangles and add

Answer 2

Answer:

238 meters

Step-by-step explanation:

Perimeter? The equation is P = 2 ( l * w )

So lets cut this irregular shape into 2 rectangles.

I added a picture to show you.

So on rectangle is 7 by 11 and the other is 7 by 6.

So lets find the perimeter of the larger rectangle first.

P = 2 ( 11 * 7 )

P = 2 ( 77 )

P = 154

Now the smaller one

P = 2 ( 7 * 6 )

P = 2 ( 42 )

P = 84

Now to find the full perimeter, add both perimeters together

P = 154 + 84

P = 238

238 meters

At angle θ lies in Quadrant III. If cosθ=-0.487, what is tanθ rounded to the nearest thousandth??

Answers

Answer:

TanФ=-1.793

Step-by-step explanation:

[tex]Sin^{2} (A) + Cos^{2} (A) = 1[/tex]

[tex]Sin(A)=\sqrt{1-Cos^{2} (A)}[/tex]

[tex]Tan(A) = \frac{Sin(A)}{Cos(A)}[/tex]

[tex]Tan(A) =\frac{\sqrt{1-Cos^{2}(A) } }{Cos(A)} \\Tan(A) =\frac{\sqrt{1-(-.487)^{2} } }{-.487}=-1.793433202[/tex]

A tropical punch recipe calls for 300 ml of sugar for every 222 flavor packages. Write an equation that shows the relationship between s, the amount of sugar in milliliters, and f, the number of flavor packages for this recipe.

Answers

Answer:

s = 150f

Step-by-step explanation:

A tropical punch recipe calls for 300 ml of sugar for every 2 flavor packages. Write an equation that shows the relationship between s, the amount of sugar in milliliters, and f, the number of flavor packages for this recipe.

The amount of sugar in milliliters = s

The amount of flavor packages for these recipe = f

The relationship between 2 variables

= y ∝ x

y = kx

k = constant of proportionality

Hence:

s ∝ f

s = kf

Note ,

s = 300

f = 2

300 = 2k

k = 300/2

k = 150

Therefore, the equation that shows the relationship between s, the amount of sugar in milliliters, and f, the number of flavor packages for this recipe is:

s = kf

s = 150f

Answer:

2=150f

Answers

Answer:

∠7 = 90°

Step-by-step explanation:

∠7 = 180 - 90

∠7 = 90°

see image below

Answer:

90°

Step-by-step explanation:

angle 7 is supplementary to the angle next to itself which has a measurement of 90° and since the sum of two supplementary angle would be 180° we can say that m<7 = 90° as well

Find the values of a and b please I will mark brainliest. (make sure to show your work)

Answers

Answer:

a = 29

b = 20

Step-by-step explanation:

2a - 1 = 57

+ 1 + 1

2a = 58

/ 2 / 2

a = 29

2a - 1 + 7b - 17 = 180

2 (29) - 1 + 7b - 17 = 180

58 - 1 + 7b - 17 = 180

57 + 7b - 17 = 180

7b + 40 = 180

- 40 - 40

7b = 140

/ 7 / 7

b = 20

Ted has an impressive total of 145 dimes and quarters. The collection is worth $24.25.
How many dimes and quarters does he have?

Answers

9514 1404 393

Answer:

80 dimes65 quarters

Step-by-step explanation:

Let q represent the number of quarters (the higher-value item). Then 145-q is the number of dimes. The total collection is worth ...

0.25q + 0.10(145 -q) = 24.25

0.15q = 9.75 . . . . . . . . . . . . . . . . subtract 14.50; collect terms

q = 65 . . . . . . . . . . . divide by 0.15

d = 145 -q = 80

Ted has 80 dimes and 65 quarters.

___

Check

80 dimes: $8.00

65 quarters: $16.25

Total: $8.00 +16.25 = $24.25.
