1-

Given length is 91 cm

1 cm = 0.3937 inch

so, 91 cm = 91* 0.3937 = 35.826 inches

1 day = 24 hours

In 24 hours the bamboo grows = 35.826 inches

In one hour it will grow = \frac{35.826}{24}

= 1.492 inches per hour. Hence the bamboo grows 1.492 inches per hour.


2-

We have to convert hours and seconds in minutes.

1 hour = 60 minutes

so 10 hours = 60 * 10 = 600 minutes.

60 seconds = 1 minute

so 24 seconds = \frac{24}{60} = 0.4 minutes.

Now we have been given the total time as 10 hours, 39 minutes and 24 seconds

So adding all values in minutes, we get

600 + 39 + 0.4 = 639.4 minutes

So Saturn takes 639.4 minutes to complete one rotation

3-

Given equation is 0.4(30h)+30h

0.4(30h) represents the amount of tax Kimberly has to pay.

Can you please hely me and tell me if my answer is right
Troyanec [42]

Answer:

x = (8√3)/3

Step-by-step explanation:

Reference angle = 30°

Hypotenuse = x

Side length adjacent to reference angle = 4

Apply CAH, thus:

Cos 30 = Adj/Hyp

Cos 30 = 4/x

x × Cos 30 = 4

x = 4/Cos 30

x = 4/(√3/2) (cos 30 = √3/2)

x = 4 × 2/√3

x = 8/√3

Rationalize

x = (8 × √3)/(√3 × √3)

x = (8√3)/3

The radius of a circular rug is 4 feet. How much ribbing will you need to buy to go around the rug? Use 3.14 for ?. A) 13 feet B
Amiraneli [1.4K]

Answer:

C =25.12 ft

I would get 26 ft

B) 26 feet

Step-by-step explanation:

To go around the rug, we are looking for circumference

C = pi*d = 2*pi*r

C = 2*pi*4

C = 8pi

We are approximating pi by 3.14

C = 8*3.14

C =25.12 ft

Please help…………..i have more to ask
ololo11 [35]

Answer:

YES

Step-by-step explanation:

Find each length using the distance formula, d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

✔️Distance between A(-4, 2) and B(1, 4):

AB = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

Let,

A(-4, 2) = (x_1, y_1)

B(1, 4) = (x_2, y_2)

AB = \sqrt{(1 - (-4))^2 + (4 - 2)^2}

AB = \sqrt{(5)^2 + (2)^2}

AB = \sqrt{25 + 4}

AB = \sqrt{29}

✔️Distance between C(2, -1) and D(4, 4):

CD = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

Let,

C(2, -1) = (x_1, y_1)

D(4, 4) = (x_2, y_2)

CD = \sqrt{(4 - 2)^2 + (4 - (-1))^2}

CD = \sqrt{(2)^2 + (5)^2}

CD = \sqrt{4 + 25}

CD = \sqrt{29}

AB = CD = √29

Therefore, they both have the same length.
