4. How many terms of the series 64 + 32 + 16 + ... ... must be taken so
that the sum may be 255÷2​

Answers

Answer 1

Answer:

... ... = .5

Step-by-step explanation:

I'm not sure if I'm right. But I got my answer by dividing 255 and 2 first

255 / 2 = 112.5

Then find out what 64 + 32 + 16.

64 + 32 + 16 = 112

Add 0.5 to get the same answer from 255 / 2

64 + 32 + 16 + 0.5 = 112.5

A skating rink changes one admission price for adults and a different admission price for children. The total admission price for a group of 4 adults and 10 children is $57. The total admission price for a group of 3 adults and 7 children is $41. What are the admission prices for an adult and for a adult?

Answers

Given:

The total admission price for a group of 4 adults and 10 children is $57.

The total admission price for a group of 3 adults and 7 children is $41.

To find:

The admission prices for an adult and for a children.

Solution:

Let the price of an adult be x and price of children be y.

According to the question,

[tex]4x+10y=57[/tex]         ...(i)

[tex]3x+7y=41[/tex]      ...(ii)

Multiply equation (i) by 3.

[tex]12x+30y=171[/tex]         ...(iii)

Multiply equation (i) by 4.

[tex]12x+28y=164[/tex]      ...(iv)

Subtract (iv) from (iii).

[tex]12x+30y-12x-28y=171-164[/tex]

[tex]2y=7[/tex]

Divide both sides by 2.

[tex]y=3.5[/tex]

Put y=3.5 in (i).

[tex]4x+10(3.5)=57[/tex]

[tex]4x+35=57[/tex]

[tex]4x=57-35[/tex]

[tex]4x=22[/tex]

Divide both sides by 4.

[tex]x=5.5[/tex]

Therefore, the price for an adult is $5.5 and price for a child is $3.5.

Step-by-step explanation:

how do you solve 2 - 2n = 3n + 17

Answers

First add 2n to 3n u get 5n
2=5n+17
Subtract 17 to both sides
-15=5n
Divide 5 both sides
N=-3

Final Answer: [tex]n = -3[/tex]

Steps/Reasons/Explanation:

Question: How do you solve [tex]2 - 2n = 3n + 17[/tex]?

Step 1: Subtract [tex]2[/tex] from both sides.

[tex]-2n = 3n + 17 - 2[/tex]

Step 2: Simplify [tex]3n + 17 - 2[/tex] to [tex]3n + 15[/tex].

[tex]-2n = 3n + 15[/tex]

Step 3: Subtract [tex]3n[/tex] from both sides.

[tex]-2n - 3n = 15[/tex]

Step 4: Simplify [tex]-2n - 3n[/tex] to [tex]-5n[/tex].

[tex]-5n = 15[/tex]

Step 5: Divide both sides by [tex]-5[/tex].

[tex]n = -\frac{15}{5}[/tex]

Step 6: Simplify [tex]-\frac{15}{5}[/tex] to [tex]-3[/tex].

[tex]n = -3[/tex]

This formula is used to calculate the weekly pay of a letting agent. Weekly pay = basic pay + number of houses rented x bonus The basic pay is £400 and a bonus of £75 is paid for each house rented. Mrs Lewis rents out 5 houses in one week. Calculate her pay.

Answers

Answer:

£775

Step-by-step explanation:

From the question, it was given that:

Weekly pay = basic pay + number of houses rented x bonus

This expression can be used to determine the amount of money being paid to the agent every week.

When basic pay = £400, bonus = £75, and the number of house rented = 5.

Then,

Weekly pay = 400 + 5(75)

                    = 400 + 375

                    = 775

Weekly pay = £775

The amount of money paid to Mrs Lewis every week is £775.

Brad has recorded insect activity data for 40 days. He has recorded 1/6 of the data needed for his science fair project. How many total days does he need to record data? Write an equation and  explain how you used it to find your answer​

Answers

Answer:

40/6= 6.6667(20/3)

Step-by-step explanation:

I divided the number of days into 6.

Answer:

[tex]x = 240 days[/tex]

Step-by-step explanation:

If we know that Brad completes 1/6 of his project every 40 days, that means it will take him 40 x 6 days to complete this project. If where to write this down as an equation we get the following.

Let "x" be the total number of days Brad needs to finish his project, then....

[tex]\frac{1}{6} x = 40 days[/tex]

[tex](\frac{1}{6} x)(6) = (40)(6)days[/tex]

[tex]x = 240 days[/tex]

1. After running, Maggie is 3 miles east of her starting point, and 4 miles north of her starting point. What angle could represent her direction of travel?​

Answers

Answer:

The angle is 53.13 degrees

Step-by-step explanation:

Here, we want to calculate angle representing the direction of travel

From the question, she is 3 miles east and 4 miles north of her starting point

So the angle that represents her direction of travel will be that which makes a cut with the horizontal (the east direction)

Now, let us picture a right-angled triangle, with 3 miles direction being the adjacent and the 4 miles direction (facing the angle we want to calculate and is the opposite)

the trigonometric identity to use is the Tangent

Tan theta = 4/3

theta = arc tan (4/3)

theta = 53.13 degrees
