adult tickets cost 1.25
Child tickets cost 0.75p
you sell 80 tickets for 7500p
How many are adult tickets and how many are child tickets

Answers

Let x = the number of adult tickets you sold.
Naturally, the number of child tickets you sold would be 80-x.
1.25x + 0.75(80-x) = 75
1.25x + 60 - 0.75x = 75
0.5 x = 15
x = 30
adult tickets = 30
child tickets = 80-30 = 50

During a football game, the ball is placed 20 yards 2 feet from the goal line. How many feet from the goal line is the football?

Answers

Answer:

62 feet

Step-by-step explanation:

During a football game, the ball is placed 20 yards 2 feet from the goal line. How many feet from the goal line is the football?

Step 1

We convert 20 yards to feet

1 yard = 3 feet

20 yards = x feet

Cross Multiply

1 yard × x feet = 20 yards × 3 feet

x feet = 20 yards × 3 feet/1 yard

x feet = 60 feet

Step 2

How many feet from the goal line is the football?

This is calculated as:

20 yards 2 feet =

60 feet + 2 feet = 62 feet

Therefore, the football is 62 feet from the goal line

Cuánto tiempo debe transcurrir para que un capital de $3,000.00 alcance un monto de $7,000.00, si la inversión se hizo con 5% de interés simple mensual?

Answers

Answer:

27 years approx

Step-by-step explanation:

Given data

Principal P= $ 3,000

Final amount A= $ 7000

Rate r= 5%

The simple interest expression is

A=P(1+rt)

substitute and solve for t

7000=3000(1+0.05t)

7000=3000+150r

7000-3000=150r

4000=150t

t= 4000/150

t= 26.66

Hence, the time is 27 years approx

EZ Excavation: y = 24.5x

Happy Hauling Service: y = 25x

Step-by-step explanation:

✔️Equation for EZ Excavation:

This can be written in slope-intercept form, y = kx

Where k is the unit rate/slope/constant of proportionality

y = cost

x = dirt

Thus,

k = y/x

Using any given pair of values from the table, say, (8, 196),

k = 196/8

k = 24.5

To write the equation, substitute k = 24.5 into y = kx

Thus:

y = 24.5x

✔️Equation for Happy Hauling Service:

This can be written in slope-intercept form, y = kx

Where k is the unit rate/slope/constant of proportionality

y = cost

x = dirt

Thus,

k = y/x

Using the coordinate of any point on the line, say (1, 25),

k = 25/1

k = 25

To write the equation, substitute k = 25 into y = kx

Thus:

y = 25x

A rectangle is 7 ft by 12 ft. Find the length of its diagonal. Round to the nearest tenth.

Answers

Answer:

13.9

Step-by-step explanation:

7² x 12² = 49 + 144 = 193

√193= 13.89

Divide the rectangle into two right triangles, like in the photo

you now have two congruent right triangles with 7ft and 12ft long legs

Use the pythagorean theorem to find the missing diagonal length (aka hypotenuse)

7^2 + 12^2 = c^2

49 + 144 = c^2

c^2 = 193

Square root both sides to get rid of the ^2

c = 13.9 ft

Answers

Answers

Answer: The answer is D

Step-by-step explanation:

Circle A has translated 2 units to the right and 8 units up to produce circle B ad circle B was reduced by a factor of 3/4

Transformation of coordinates

Given the equation of circles A and B defined as (x-5)^2+(y-6)^2=16 and (x+3)+(y+2)^2=9

The scale factor of a dilation is given as:

k = √9/√16

k = 3/4
