Three years back, afather was 24 years older than his son at present the father is 5 times as old as the son how old will the son be three years from now?​

Answers

Answer:

Let current age of father be x and current age of his son be y.

So 3 years ago, difference between their age was 24.

Therefore equation becomes

(x-3)-(y-3) = 24.

x - y = 24.

At present father is 5 times as old as son.

x = 5y.

Therefore 5y - y = 24.

y = 6.

Current age of son is 6 years. So after three years he will be 9 years old.

Step-by-step explanation:

One year, an athlete won a gold medal with a long jump of some
meters. Several years later, another athlete won a gold medal with a
long jump of 7.12 meters. The second jump was 0.13 meters longer
than the first. How long was the first jump? Write an equation
and solve.

Answers

Answer:

6.99 meters

Step-by-step explanation:

For this we have to use subtraction:

So if the second jump was .13 meters longer then the first and we know the second jump was 7.12 meters, we have to subtract 7.12 by .13 to get the length of his/her's first long jump. So our equation is 7.12-.13=length of first jump. So we end up getting 6.99=length of first jump.

Hope this helps! :D

Answers

Answer:

1. (6,3)

2. x = 850, y = 150

Step-by-step explanation:

1. 3x-5y=3

4x-15y=-21

-9x +15y=-3 (multiply by -3)

4x-15y=-21

-5x=-30

x = 6

3(6)-5y=3

18-5y=3

-5y= -15

y= 3

so, x = 6, y = 3

2.

let x be regular

let y be reserved

x+y=1000

x= 5, y= 5+2=7 ("2 dollar more")

5x+7y=5300

x+y=1000

use the elimination method

x=850, y=150

so, the regular tickets were 850 and reserved tickets were 150 sold.

A circle has a diameter of 6, an area of b square units, and a circumference of c units. What is the value of b + c ?

Answers

Answer:

Step-by-step explanation:

Diameter = 6 units

Radius = Diameter/2 = 6/2 = 3 units

Taking π=3.14

Circumference = 2(π)(r) = 2(3.14)(3) = 6(3.14) = 18.84 = c

c = 18.84

Area = π(r)^2 = π(3)^2 = 9π =9(3.14) = 28.26 = b

b = 28.26

So,

b + c = 28.26 + 18.84 = 47.1

Answer:

b=6π the unit(cm)

c=18.84 the unit(cm)

b+c=

9+18.84=27.84

Step-by-step explanation:

circumference=c

diameter=d

radius=r

area=b

d=2r

6=2r

6=r

2

r=3

b=πr^2

b=3×3π

=9π

c=2πr

=2(3.14)3

= 3.14×6

=18.84

Taylor and Anya live 36 miles apart.On Some Saturdays.They ride theirs Bikes toward each other's houses and meet somewhere in between. Taylor is very Consistent rider she finds that her speed is always close to 12.5 miles per hour.Anya rides more slowly than Taylor, but she is working out and is becoming a faster rider as the weeks go by.On a Saturday in July, the two friends set out on their bikes at 8 a.m.Taylor rides at 12.5 per hour and Anya rides at 5.5 miles per hour.After one hour, how far apart are they? Show your work and Explain your Answer.​

At What Time will the two friends meet?How do you know? Show your Work and Explain your Answer.

Answers

Answer:

Taylor and Anya will meet at 10:00 a.m.

Step-by-step explanation:

If Taylor rides at 12.5 mph (miles per hour), and Anya rides at 5.5 mph (miles per hour), then we need to combine these ratios to see how far apart they will be in one hour.

12.5 mph + 5.5 mph = 18 miles

Therefore, after an hour, Anya and Taylor are 18 miles apart.

Since there houses are 36 miles apart, and 18 x 2 = 36, then we can infer that it will take two hours, two times the time it took for them to finish halfway of their journey, for them to meet.

8:00 a.m. + 2 hours = 10:00 a.m.

Therefore, Taylor and Anya will meet at 10:00 a.m.

3. The cost(P) in Ghana Ghana Cedis, of producing n items is given by the formula, P=3/4n + 1800. a. Find the cost of producing 2000 items il formulas.​

Answers

Answer:

3300

Step-by-step explanation:

P = 3/4n + 1800

P = 3/4(2000) + 1800

P = 3 × 500 + 1800

P = 1500 + 1800

P = 3300

Therefore, the cost of producing 2000 items is GHC 3,300.

cost of producing 2000 items =3300

Solution:-

P = 3/4n + 1800

P = 3/4(2000) + 1800

P = 3 × 500 + 1800

P = 1500 + 1800

P = 3300

Therefore, the cost of producing 2000 items is GHC 3,300.

There are 6 ways of arranging 9,5 and n.
Two have been used so the answer must be one of 59n, n95, 9n5 and 5n9
I will show one wrong and then the correct answer

95n - n59 = 5n9
950 + n - 100n - 59 = 509 + 10n
891 - 99n = 509 + 10n
382 = 109n
n = 382/109 wrong

95n - n59 = n95
950 + n - 100n - 59 = 100n + 95
891 - 99n = 100n + 95
796 = 199n
n = 796/199 = 4

So 954 - 459 = 495

The test of validity is used to determine whether a claim is true or not, based on certain condition(s).

The validity of the given statement is true.

From the question, the given condition is:

Whenever he participates in a race, he is the winner

This can be interpreted as follows:

He wins all races he participates in.He doesn't win a race he doesn't participate in.

So, if he is sick; it means that he does not participate in the race and as such he is not the winner.

Answers

Answer:

Explanation:

For every mile $0.20 is charged
