If 3 varies inversely as x and y=2 when x=25, find x when y=40

Answers

since y varies inversely as x , the equation is y=k/x....... Then you plug in 2 for y and 25 for x to find K....... After that you get K= 50...... Then plug in 50 for K and 40 for y then solve for x....... After that you get X= 1.25

PLEASE HELP WHATS THE ANSWER

Answers

Answer:

2,744

Step-by-step explanation:

[tex]C = 400 \sqrt[3]{n} + 200 \\ \\ plug \: C =5800 \\ \\ 5800 = 400 \sqrt[3]{n} + 200 \\ \\ 5800 - 200 = 400 \sqrt[3]{n} \\ \\ 5600 = 400 \sqrt[3]{n} \\ \\ \frac{5600}{400} = \sqrt[3]{n} \\ \\ 14 = \sqrt[3]{n} \\ \\ {(14) }^{3} = {(\sqrt[3]{n})}^{3} \\ (cubing\: both\: sides) \\\\ 2,744 = n \\ \\ n = 2,744[/tex]

a sphere has a volume of 905cm. what is the radius of the sphere rounded to the nearest whole number ?

Answers

Answer:

r = 6

Step-by-step explanation:

The value of radius of the sphere rounded to the nearest whole number is,

⇒ r = 6 cm

We have to given that,

Volume of a sphere = 905 cm

Since, We know that,

Volume of sphere = 4/3 (πr³)

Where, 'r' is radius of sphere.

Now, Substitute the given value, we get;

⇒ 905 = 4/3 (πr³)

⇒ 905 × 3 = 4 × 3.14 × r³

⇒ 2,715 = 12.56 × r³

⇒ r³ = 216.16

⇒ r = ∛216.16

⇒ r = 6 cm

Thus, The value of radius of the sphere rounded to the nearest whole number is,

⇒ r = 6 cm

Jim makes $5 an hour at the surf shop. His boss gives him a one-time bonus of $50. Sarah makes $8 an hour at the clothes store. Her boss givers her a one-time bonus of $14. If they both work 15 hours, who will have a bigger paycheck?

Answers

Answer:

Sarah had the bigger paycheck of $134

Step-by-step explanation:

First we would need to find the total amount of money each one of them made in those 15 hours. We do this by multiplying their hourly rate by the hours worked and then adding the bonus

Jim:  (5*15) + 50 = x

          75 + 50 = x

              125 = x

Sarah: (8 * 15) + 14 = x

             120 + 14 = x

                  134 = x

Finally, we can say that Sarah had the bigger paycheck of $134 which is $9 more than Jim's

the ratio of two sums of money are 4:5. the first sum is $6. what is the second?

Answers

7.5
Cross multiply (4•x) and (5•6) and get 30=4x
X=7.5

The second sum of money is $7.5

The ratio of the sum is given as:

Ratio = 4 : 5

Represent the second sum of money with x.

So, we have:

4 : 5 = 6 : x

Express the ratio as a fraction

4/5 = 6/x

Make x the subject of formula

x = 6 * 5/4

Evaluate the product

x = 7.5

Hence, the second sum of money is $7.5

c) Work out an estimate for the number of times
coin B will land on Heads.
(2)
Total marks: 5

Answers

Answer:

Please check explanations for answer

Step-by-step explanation:

Firstly, we need all the probability in the same decimal form

P(A) = 0.66

P(B) = 0.067

P(C) = 2/3 = 0.67

P(D) = 60/100 = 0.6

a) The least likely is the smallest value of decimal

This is 0.067 which is for coin B

most likely is the highest probability; this is C which is 2/3

b. Probability that D will land on tail is 1 - probability that it lands on head

= 1 - 0.6 = 0.4

c. Mathematically that is the product of the probability and the number of times it was thrown

That will be;

0.066 * 4000

= 264 times

Answers

Answer:

24 = x

Step-by-step explanation:

You use Pythagorean theorem. Since the normal equation is [tex]a^{2} + b^{2} =c^{2}[/tex], you already have the [tex]c^{2}[/tex] and another side which can be [tex]a^{2}[/tex] or [tex]b^{2}[/tex].

Because you have the hypotenuse and a side , your equation looks like this now: [tex]7^{2} +b^{2} = 25^{2}[/tex]

and when you solve for be you just subtract [tex]25^{2} -7^{2}[/tex] to get 24.
