Find The Value Of Cos F Rounded To The Nearest Hundredth, If Necessary. E 6 F 8 10 D

Answers

Answer 1

Answer:

cosF = 0.6

Step-by-step explanation:

cosF = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{EF}{DF}[/tex] = [tex]\frac{6}{10}[/tex] = 0.6

Answer 2

Answer:

Cos F = 0.6

Step-by-step explanation:

Trigonometry ratios:

    [tex]\sf \boxed{\bf \ Cos \ F = \dfrac{adjacent \ side \ of \ \angle F}{hypotenuse}}[/tex]

                   [tex]\sf =\dfrac{EF}{DF}\\\\=\dfrac{6}{10}\\\\= 0.6[/tex]

If the length of the longest side of the rectangle is 20cm find the shaded area to the nearest hundredth

Answers

Answer:

Step-by-step explanation:

diameter of each circle = 20/2 = 10 cm

rectangle is 20 cm by 10 cm

area of rectangle = 20×10 = 200 cm²

radius of each circle = 10/2 = 5 cm

area  of each circle = πr² = 25π cm²

shaded area = 200  - 2(25π) = 200 - 50π =42.92 cm²

Answer:

50 minutes left.

Step-by-step explanation:

The easiest way to do this is to convert all the fractions into minutes

So, she would've spent 1 hour and 30 minutes on her homework and 40 minutes on her telephone. If you add those amounts up, you get 2 hours and 10 minutes. Since she goes to bed 3 hours after dinner, and 2 hours and 10 minutes have gone by, you do 3 hours - 2 hours 10 minutes and you get 50 minutes.

Hope that makes sense. Let me know if you have any questions.

Find x and y plz help

Answers

Based on the angles, we know this is a 45-45-90 triangle.

In this type of triangle, x and y will be equal. The formula for the sides is x * rad 2 = 8 .

8/ rad 2 = 5.66

Both X and Y are 5.66 units.

Answer:

x = 6.81 and y = 4.20

Step-by-step explanation:

by using SOHCAHTOA

hypotenus = 8

adjacent = x

opposite = y

sin45° = y/8

y = 8sin45°

y = 6.66

cos45° = x/8

x = 8cos45°

x = 5.66

Answers

Answer:

1: 65 in^2

2. 55 ft^2

Step-by-step explanation:

1. First you have to find the area of the trapezoid using the formula (a+b)h/2 where a= 10, b=15, and h=8. The answer will be 100. Then subtract the area of the square inside, which is 35. The final answer is 65.

2. Subtract from the dimensions of the landscape to find the dimensions of the patio. The length of the patio is 11 ft and the width is 5 ft. Therefore, the area is 55 ft^2

Answer:

Alright, helping you because I feel bad. 1) 76 in. 2) 24 in.

Step-by-step explanation:

1. [tex]A= \frac{a+b}{2} h[/tex]    a= base b= base h= height   Plug in the numbers, [tex](\frac{10+15}{2} ) 8= 100[/tex], but we still need to subtract the area of the un-shaded region (5×2)+(7×2)= 24

100-24= 76

2. Find the area of both landscaping rectangles, including the patio bit.

(14×2)+(8×2)=

28+16=

44in.    The two rectangles are the same size, so they both have an equal area. Now we find the area of just the patio spot, W= (8-3)×2  L= (14-3)×2 W= 10 L= 22  A=32 in.

Now, we multiply by two, since we counted it twice, 64 in.

Finally, subtract 64 from the the sum of the two areas from the landscape rectangles,  88-64= 24 in.

w is directly proportional to u if w=5 when u=3,find u when w is =2/7​

Answers

Answer:

u = 6/35

Step-by-step explanation:

w = k * u

w = ku

Where

k = constant of proportionality

if w=5 when u= 3

w = ku

5 = k * 3

5 = 3k

k = 5/3

find u when w is =2/7​

w = ku

2/7 = 5/3 * U

2/7 = 5/3u

u = 2/7 ÷ 5/3

= 2/7 × 3/5

= (2*3)/(7*5)

= 6/35

u = 6/35

The wife of a rich man fell sick: and when she felt that her end drew nigh, she called her only daughter to her bedside, and said, "Always be a good girl,and I will look down from heaven and watch over you." Soon afterwards she shut her eyes and died, and was buried in the garden; and the little girl wentevery day to her grave and wept, and was always good and kind to all about her. And the snow spread a beautiful white covering over the grave; but by thetime the sun had melted it away again, her father had married another wife. This new wife had two daughters of her own: they were fair in face but foul atheart, and it was now a sorry time for the poor little girl.
