Given that x:y=5:1 find 4x+5y:3x

Mathematics
1 answer:
kotykmax [81]4 years ago
6 0

Answer:

5:3

Step-by-step explanation:

When the ratio says x:y=5:1, it means that x is 5 times greater than y. So, plug in 5 for x and 1 for y.

4(5)+5(1):3(5)

20+5:15

25:15 , if simplified then the ratio 5:3

Credit cards place a three digit security code on the back of cards. What is the probability that a code starts with the number
yan [13]
<h2>Answer:</h2>

The probability that a code starts with the number 7 is:

                          1/10

<h2>Step-by-step explanation:</h2>

There are total 10 digits:

0   1   2    3    4   5   6   7   8   9

Also, the total number of codes that are possible using these digits are:

                            1000

( Since there are 10 choices for first place, 10 for second and 10 for third as well

Hence, total possibilities are: 10×10×10=1000 )

Also, if the first place of the code is fixed with number 7.

So, we need to chose the digits for second and third place.

Hence, total codes whose first digit is 7 are:

                      100

( Since the choice for first place is fixed and for second and third place we have 10 choices i.e. total such cases are: 1×10×10=100   )

Hence, the probability is calculated as:

            Probability=100/1000

                               =1/10

9 cm and the other leg measures 11 cm. Find the measure of the hypotenuse. If necessary, round to the nearest tenth.
nasty-shy [4]

Answer:

14.2 cm

Step-by-step explanation:

The hypotenuse of a triangle is measured using the pythagorean theorem. This formula sums up the squares of both legs of the triangle which would give the squared value of the hypotenuse. Therefore, we can then square root that value to find the hypotenuse. This would be the following...

9^{2} + 11^{2} = x^{2}

81 + 121 = x^{2}

202 = x^{2}

14.21 = x^{2}

Finally, we can see that the value of the hypotenuse is 14.2 cm

a motorist starts from O nd moves in a direction 030° for 36km.he then moves 7km towards the west .how far east his he now from
gavmur [86]

Answer:

  11 km

Step-by-step explanation:

Assuming your "direction 030°" is a bearing measured clockwise from north, the amount the motorist moved east on the first leg of the journey was ...

  (36 km)sin(30°) = 18 km

From that point, moving 7 km west makes his easterly position ...

  18 km -7 km = 11 km . . . . east of O

_____

The sine of an angle is the ratio of the side opposite to the hypotenuse. You can find the length of the side opposite (the easterly motion) by multiplying the sine of the bearing angle by the distance of travel. A diagram can help.
