Troy and Lisa were shopping for school supplies. Each purchased different quantities of the same notebook and thumb drive. Troy bought 4 notebooks and 5 thumb drives for $116. Lisa bought 2 notebooks and 3 thumb drives for $68. Find the cost of each notebook and each thumb drive.

Answers

Answer:NOTEBOOK= 4

THUMB DRIVE=20

Step-by-step explanation:

The cost of thumbdrive and notebook purchased are $20 and $4 respectively

Let :

Cost of Notebooks = n

Cost of Thumb drive = t

Troy :

4n + 5t = 116 - - - - (1)

Lisa :

2n + 3t = 68 - - - - (2)

Solving by elimination :

Multiply (1) by 2 and (2) by 4

8n + 10t = 232 - - - (3)8n + 12t = 272 - - - (4)

Subtract (3) and (4)

-2t = - 40t = 40 ÷ 2 = 20

From (1)

4n + 5(20) = 1164n + 100 = 1164n = 116 - 1004n = 16n = 16 ÷ 4 = 4

Hence, cost of notebook is $4 and cost of thumbdrive is $20

What percentage of the shape is purple?
Write your answer using a percent sign (%).
(Please help!) almost done 3

Answers

Okay, we see that there are 10 pieces in the circle - thus, it is our denominator. Next, we see that 9 out of them are coloured in. Therefore, the fraction is 9/10. To express our answer as a percent, we need to divide 9 and 10 to get 0.9. Then, we multiply 0.9 by 100 to get 90%. As a result, your answer is 90%.

The percentage of the shape that is purple is approximately 90%.

To find the percentage of the shape that is purple, we need to calculate the proportion of purple pieces out of the total number of pieces and express it as a percentage.

Given that there are 10 pieces in total and 9 of them are colored in, we can calculate the percentage as follows:

Percentage of purple pieces = (Number of purple pieces / Total number of pieces) × 100

Percentage of purple pieces = (9 / 10) × 100

Percentage of purple pieces = 0.9 × 100

Percentage of purple pieces = 90%

Therefore, the percentage of the shape that is purple is approximately 90%.

how many sides does a regular polygon have if the measure of an interior angle is 160 degrees? justify ur answer EXPLAIN HOW PLSSS

Answers

Step-by-step explanation:

Size of Interior angle = 180° - 360°/n, where n is the number of sides of the regular polygon.

We have 180° - 360°/n = 160°.

=> 360°/n = 20°, n = 18.

Therefore it is a 18-sided regular polygon.

A bouncy ball is dropped such that the height of its first bounce is 6.25 feet and each

successive bounce is 80% of the previous bounce's height. What would be the height

of the 11th bounce of the ball?

Answers

Answer:

0.67 feet

Step-by-step explanation:

This question can be interpreted as find the 11th term of a geometry progression where a = 6.25 and r = 80%

So, we have:

[tex]T_n = ar^{n-1}[/tex]

In this case:

[tex]r - 80\% = 0.8[/tex]

[tex]n = 11[/tex]

So, we have:

[tex]T_{11} = 6.25 * 0.8^{11-1}[/tex]

[tex]T_{11} = 6.25 * 0.8^{10}[/tex]

[tex]T_{11} = 6.25 * 0.1073741824[/tex]

[tex]T_{11} = 0.67ft[/tex]

Hence, the height of rebound at the 11th time is approximately 0.67

A bottie contains 255 coins.

1/3 of the coins are £1 coins.

110 of the coins are 50p coins.

The rest of the coins are 20p coins.

Work out the total value of the coins contained in the bottle.

Answers

Answer:

£152

Step-by-step explanation:

Solution:

Find out how much is 1/3 of 255 coins:

255 x 1/3 = 85

Since you know how many 50p and £1 coins there are, the remaining of the coins after the 50p and £1 get deducted from the total coins.

255 - 85 - 110 = 60

There are 60 20p coins, 85 £1 coins and 110 50p coins.

Find out the total value by calculating them all altogether.

60 x 20p = 1200

85 x 100p which is £1 = 8500

110 x 50p = 5500

I did them separately so that it wouldn't be so confusing.

Convert them into £, then after that add them up.

£12 + £85 + £55 = £152

Determine the length of a chord whose central angle is 65° in a circle with a radius of 9 feet.
Question 5 options:


1)
4.84 feet


2)
9 feet


3)
9.67 feet


4)
8.16 feet

Answers

Answer:

3)

9.67 feet

Step-by-step explanation:

The length of the chord is approximately 8.16 feet. The correct option is 4.

What is the length of the chord of the circle?

A line segment connecting two points on a circle is referred to as a circle's chord in geometry. The circle's center is traversed by the longest segment that can be drawn between any two points on the circle.

To get the chord's length, we can utilize the formula for a circle's chord length. The equation is:

Length of chord = 2r sin(θ/2)

where r is the circle's radius, is its radian central angle, and sin is the sine function.

First, we need to convert the central angle from degrees to radians:

θ = 65° = (65/180)π = 1.14 radians

Now we can plug in the values:

Length of chord = 2(9 feet) sin(1.14/2) ≈ 8.16 feet

Therefore, the length of the chord is approximately 8.16 feet.
