An office supply store in san diego sells 7 writing tablets and 4 pens for $6.40 also two tablets and 19 pens cost $5.40 find the price of each

Answers

7t + 4p = 6.40
2t+ 19p = 5.40

Let’s substitute equation 1 in equation 2

T= (6.40 -4p)/7

2(6.4-4p)/7)) +19p=5.4
(12.8-8p)/7 +19p = 5.5

0.25 r – 0.125 + 0.5 r = 0.5 + r

solve for r please show steps so i can actually understand.,

Answers

0.25r - 0.125 + 0.5r = 0.5 + r
Step 1: Move all similar terms (r) to the same side of the equation by
subtracting "r" from each side of the equation
0.25r - 0.125 + 0.5r - r = 0.5
Move terms without r to the other side of the equation, by adding +0.125 to each side of the equation
0.25r + 0.5r - r = 0.5 + 0.125
Add similar terms, note that r is equal to 1r
0.75r - 1r = 0.625
-0.25r = 0.625
Solve for r by dividing both sides of the equation by -0.25
r= 0.625/(-0.25)
r=-2.5

Scott is beginning racquetball at a club. his equipment will cost $67.95, the fees are $70 membership plus $5.50 per hour for 40 hours, and he will make 30 trips at $1.34 per trip. what are his total costs?

Answers

Total cost = $67.95 + $70 + ($5.5 × 40) + (30 × $1.34)

Total cost = $398.15

Answer: Total cost will be $398.15.

Step-by-step explanation:

Since we have given that

Cost of his equipment = $67.95

Cost of membership fees = $70

Cost of per hour =$5.50

For 40 hours,

Cost will be [tex]5.50\times 40=\$220[/tex]

Cost of per trip = $1.34

Cost for 30 trips will be

[tex]1.34\times 30=\$40.2[/tex]

According to question,

[tex]\$67.95+\$70+\$220+\$40.2=\$398.15[/tex]

Hence, total cost will be $398.15.

2. Quadrilateral ABCD is inscribed in a circle. Find the measure of each of the angles of the quadrilateral. Show your work

Would the measure of angle B be x for this??

Answers

On this picture is shown a quadrilateral inscribed in a circle and by the Inscribed Quadrilateral Theorem the angles on the opposite vertices are supplementary, or in other words are equals to 180 degrees.

On this exercise it is asked to find the measure of angle B, First of all, you need to find the value of x. To so you have to select two opposite angles on this case angles A and C.

m<A+m<C=180 Substitute the given values for angles A and C
x+2+x-2=180 Combine like terms
2x=180 Divide by 2 in both sides to isolate x
x=90

Now, that the value of x is known you can substitute it in the expression representing angle D, and then subtract that number from 180 to find the measure of angle B.

m<D=x-10 Substitute the value of x
m<D=90-10 Combine like terms
m<D=80

m<B=180-m<D Substitute the value of angle D
m<B=180-80 Combine like terms
m<B=100

The measure of angle B is 100 degrees, and the value of x is 90.

The value of a stock share in a new technology company has been increasing at a rate of 8.6% quarterly. The initial price of one share was $102.15. An investor plans to sell once the value of one share reaches $233.10.

If t is the number of quarters since the initial price of one share was set, which equation could be used to determine how long it will take the share to reach $233.10, assuming it continues to grow at the same rate?

A. 102.15 = 233.10(0.086)t
B. 102.15 = 233.10(0.914)t
C. 233.10 = 102.15(1.86)t
D. 233.10 = 102.15(1.086)t

Answers

Answer: The correct answer would be choice D, as long as the t was an exponent.

It should be written as 233.10 = 102.15(1.086)^t

The t has to be an exponent because you are multiplying the investment by 1.086 repeatedly each quarter. We used 1.086 because we added on 8.6% (or 0.086) to the investment.

Final answer:

The correct equation to use is D. 233.10 = 102.15(1.086)^t, which represents how the value of the share increases over time assuming consistent growth. The growth factor is represented by (1.086)^t as the share is increasing by 8.6% quarterly.

Explanation:

The correct equation to determine how long it will take for the share to reach $233.10 is D. 233.10 = 102.15(1.086)^t.

This equation represents a classic compound interest formula that describes how an investment grows over time, where 102.15 is the initial share price, 1.086 is the quarterly growth rate (1+8.6%), and t is the number of quarters.

The equation shows that the future value, $233.10, is equal to the initial value, $102.15, multiplied by the growth factor, (1.086)^t, raised to the number of quarters.

If we observe these values, we can conclude that a Geometric Series is being formed.First number is multiplied by 3 to get the second number and second number is multiplied by 3 to get the third number. So the summation can be expressed using the Geometric Series.

The summation uses the general term to express the sum over the interval. So first we find the general term of geometric series.

First term of the series = 1
Common ratio = 3

So, the general term of the series will be: [tex]1(3)^{n-1} [/tex]

This general term gives the terms of given geometric series for different values of n. For n = 1, we will have the first term which will is 1. Similarly for n=2, we will have the second term which is 3.

So the summation will start with first term and end on 15th term. Therefore, correct summation for this case is expressed by first option.

20. Find the measure of each interior angle AND each exterior angles of the following regular polygons. Show your work. a. Pentagon b. 16-gon c. Dodecagon

Answers

a. Pentagon

Interior angle:

5 sides => form 5 triangles => central angle: 360 / 5 = 72°

interior angle = 2x

angles in every triangle: x => x + x + 72° = 180°

=> 2x = 180° - 72° = 108°

Answer 108°

Exterior angles = 360° / number of sides = 360° / 5 = 72°

Answer: 72°

b. 16 - gon

Interior angles: 2x

number of triangles = 16

central angle = 360 / 16 = 22.5°

interior angle 2x, where 180° - 22.5° + x + x => 2x = 180° - 22.5° = 157.5°

Answer: interior angle 157.5°

Exterior angles: 360 / 16 = 22.5°

Answer: exterior angles = 22.5°

c. Dodecagon

number of sides 12

central angle = 360° / 12 = 30°

interior angle, 2x => 30 + 2x = 180 => 2x = 180 - 30 = 150°.

Answer: interior angle = 150°

Exterior angle = 360° / number of sides = 360° / 12 = 30°

Answer: exterior angle = 30°

Which of the following best describes how to measure the spread of the data?

Answers

the best way to measure the spread of data is by the standard deviation

Final answer:

To measure the spread of data, you can use the range, variance, or standard deviation, which respectively measure the absolute difference between extremes, the average squared deviation from the mean, and the average deviation from the mean in the same units as the data.

Explanation:

The question refers to the methods used to measure the spread of data in a dataset. The spread, or variability, indicates how much the data points in a set differ from each other and from the central measures like the mean. There are several ways to quantify this spread, including:

The range, which is the difference between the largest and smallest values in the set.

The variance, which is the average of the squared differences from the mean.

The standard deviation, which is the square root of the variance and provides a measure of spread in the same units as the data.

Knowing the spread of data helps in understanding the distribution and consistency of the dataset, which is essential for statistical analysis.

A 12 sided die, numbered 1 to 12 is rolled. Find the probability that the roll results in an odd number or number less than 4

Answers

Answer:

6/12+3/12-2/12=.583

Step-by-step explanation:

6/12 amount of odd numbers

3/12 numbers less than 4

2/12 the amount of numbers that overlap

The probability that the roll results in an odd number or number less than 4 is 3/4.

Given that, a 12 sided die, numbered 1 to 12 is rolled.

What is the probability?

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favorable outcomes/Total number of outcomes

Total number of outcomes = 12

Odd numbered sides = {1, 3, 5, 7, 9, 11} = 6

Number less than 4 = {1, 2, 3} = 3

Probability of getting an odd number = 6/12

Probability of getting a number less than 4 = 3/12

So, probability = 6/12 + 3/12

= 9/12

= 3/4

Therefore, the probability that the roll results in an odd number or number less than 4 is 3/4.

Raymond has 120 books on his bookshelf that he has not read. He plans on reading 3 books per week until there are only 24 books that he still needs to read. Which equation can be used to determine the number of weeks, w, it will take Raymond to have only 24 books left, and how many weeks will it take? 3w - 24 = 120; 48 weeks 24w = 120 - 3; 4 weeks 120 - 3w = 24; 32 weeks 24w - 3 = 120; 5 weeks

Answers

⓵ The equation would be : 120 - 3w = 24

⓶ To test it out, let’s start by isolating the “W” :

120 - 3w = 24
-24 -24

↓

96 - 3w = 0
+3w +3w

↓

96 = 3w
÷3 ÷3

↓

32 = w

⓷ Now let’s see if everything works :

32 should be the number of weeks it will take Raymond to have only 24 books left!

If Raymond reads 3 books per week, how many did he read in 32 weeks?

32 × 3 = 96

If Raymond read 96 books in 32 weeks, how many books does he have left?

120 - 96 = 24

So the equation in #⓵ works!
