Mathematics
1 answer:
OLga [1]3 years ago
7 0

Answer:

1. 1072.6

2. 753.6

3. 194.2

4. 59.5

5. 4848.3

6. 1818.3

Step-by-step explanation:

We have to use the trigonometric functions sin, cos, and tan. Remember the mnemonic SOH-CAH-TOA when solving these problems. (sinθ=opposite/hypotenuse, cosθ=adjacent/hypotenuse, tanθ=opposite/adjacent)

1. tan(40)=900/x

x=900/tan(40)

x=1072.6

2. tan(37)=x/1000

1000tan(37)=x

753.6=x

3. sin(18)=60/x

x=60/sin(18)

x=194.2

4. sin(48)=x/80

80sin(48)=x

59.5=x

5. tan(22)=x/12000

12000tan(22)=x

4848.3=x

6. tan(33)=x/2800

2800tan(33)=x

1818.3=x

What is the probality of rolling a sum of 5 if two regular 6 -sides number cubes are rolled
Dmitry [639]

Each die has six numbers, the total number of possible combinations is 6 * 6 = 36


The combinations in which you can get a sum of 5 are:  1 &4, 2 & 3, 4 &1, 3 &2

There are 4 different combinations of getting a sum of 5.


The probability would be 4/36, which reduces to 1/9

How do u solve (2d-5)/2 = (5d+2)/9
Rzqust [24]

Answer:

D=  49/8

Step-by-step explanation:

Cross-multiply.

(2d-5)/2 = (5d+2)/9

(2d−5)*(9)=(5d+2)*(2)

18d−45=10d+4

Subtract 10d from both sides.

18d−45−10d=10d+4−10d

8d−45=4

Add 45 to both sides.

8d−45+45=4+45

8d=49

Divide both sides by 8.

d=  49/8

So the answer is 49/8

I hope it's right!

Theres 60 seconds in a minute. If it takes her 5 minutes, multiply 60 by 5. you will get 300. then all you will do is divide the meters by 300 seconds. you will get the answer of 1.5 metres per second.
