Answers

Answer 1

3.5% of 600...turn percent to a decimal..." of " means multiply

0.035 * 600 = 21 <=== 21 phones are likely to be defective

Answer 2

to find out how many phones are not defected, 600*96.5%=579 so 600-579 = 21 phones defected.

what is the area of a circular mirror with a radius of 10 cm?

Answers

area=pi r squared
area=3.14 x 10squared
area= 314
the answer is 314

Final answer:

The area of a circular mirror with a radius of 10 cm is calculated using the formula πr², which results in an area of 314.16 cm².

Explanation:

The area of a circular mirror can be calculated using the formula πr², where π (pi) is approximately 3.1416 and r is the radius of the circle. Given the radius of the circular mirror as 10 cm, we can substitute this value into the formula to find the area.

Area = π × (10 cm)²
A = 3.1416 × 100 cm²
A = 314.16 cm²

Therefore, the area of the circular mirror is 314.16 cm².

Laura drove to the mountains last weekend. there was heavy traffic on the way there, and the trip took 8 hours. when laura drove home, there was no traffic and the trip only took 6 hours. if her average rate was 16 miles per hour faster on the trip home, how far away does laura live from the mountains

Answers

Final answer:

To find the distance Laura lives from the mountains, calculate her average speed when driving to the mountains and use the time taken during the trip. With the given speeds and travel times, the distance can be determined using a simple equation.

Explanation:

To find the distance Laura lives from the mountains:

Let x be Laura's average speed when driving to the mountains.Since Laura drove 16 mph faster on the way home, her speed returning was x+16 mph.Distance to mountains = x * 8 (hours) and distance from mountains = (x+16) * 6 (hours).Set up the equation: x * 8 = (x+16) * 6 to solve for x.Once x is found, the distance Laura lives from the mountains can be calculated as x * 8.

Subtract the polynomials: (3x2 + 2x + 4) - (x2 + 2x + 1). Enter your answer as a polynomial in descending order below, and use the caret (^) for exponents. For example, you would write as 4x^2.

Line up the like terms like so

3x^2 + 2x + 4

2x - 2x = 0x = 0
4 - 1 = 3

The results of 2x^2, 0 and 3 are added up to get 2x^2 + 0 + 3 and that turns into 2x^2 + 3

The cruise control function on Georgina's car should keep the speed of the car within 3 miles per hour of the set speed. The set speed is 55 miles per hour. Write a compound inequality to show the leaves that are within each range. Then graph the solutions.

Answers

This should help. Sorry I had to make this rn.

Answer:

Given,

Set speed of car = 55,

∵ The speed of the car within 3 miles per hour of the set speed.

So, the maximum speed of car = 55 + 3,

And, the minimum speed of car = 55 - 3

Let x shows the current speed of car,

x ≤ 55 + 3 or x ≥ 55 - 3

x - 55 ≤ 3 or x - 55 ≥ - 3

x - 55 ≤ 3 or -(x-55) ≤ 3

⇒ | x-55 | ≤ 3

Which is the required compound inequality,

Now, 55 - 3 ≤ x ≤ 55 + 3

52 ≤ x ≤ 58

⇒ [52, 58]

Which is the solution of the above compound inequality.

Also, the graph is shown below.

Write an equation that represents degrees fahrenheit in terms of degrees celsius. let xx represent the temperature in degrees celsius and let yy represent the temperature in degrees fahrenheit.

Answers

As we know Conversion from fahrenheit to celsius is
[tex]F - 32 = \frac{9C}{5} [/tex]

We can write it also as

[tex]F = \frac{9C}{5}+32 [/tex]

F as y and C as x then we can write it as

[tex]y = \frac{9x}{5} + 32 [/tex]

An equation is formed of two equal expressions. An equation that represents degrees Fahrenheit in terms of degrees celsius is y=(9/5)x+32.

What is an equation?

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The equation to covert degrees fahrenheit to degrees celsius is given as,

(C × 9/5) + 32 = F

where C represents temperature in degrees Celcius and F represents the temperature in degrees Fahrenheit.

Now, we need to represent the degree Celcius by x, while the degree Fahrenheit by y. Therefore, the above equation can be rewritten as,

y = (x × 9/5) + 32

y = (9/5)x + 32

Hence, an equation that represents degrees Fahrenheit in terms of degrees celsius is y=(9/5)x+32.

4 pieces of wood each 11 and a half inches long are required to build a cabinet. If all four pieces are cut from one board and 1 inch is allowed for waste in cutting each piece, how long should the board be?

Answers

ok first we calculate the length of board without losses:
4 * 11.5 = 46 inches
then, we have 1 inch of waste allowed fir each piece, so the total waste is 4*1 = 4 inches

finally, we will add the length of the waste to the desired length to get the total length of the board as follows:
total length of board = 46+4 = 50 inches

if a and b are the measures of two first quadrant angles and sin a = 4/9 and sin b = 2/5 find sin (a+b)

Answers

The sine of the sum of two angles a and b, with sin a = 4/9 and sin b = 2/5, is calculated using the sine addition formula and is approximately 32.24/45.

To find sin(a+b) when given sin a = 4/9 and sin b = 2/5, we use the sine addition formula:

sin(a+b) = sin(a)cos(b) + cos(a)sin(b)

Since we have the sine values, but not the cosine values, we need to find cos(a) and cos(b). Knowing that [tex]sin^2(\theta) + cos^2(\theta) = 1[/tex]for any angle theta, we can find the cosines:

For cos(a): [tex]cos^2(a) = 1 - sin^2(a) = 1 - (4/9)^2 = 1 - 16/81 = 65/81[/tex]. So, [tex]cos(a) = \sqrt{(65/81)} = 8/9[/tex] (since a is in the first quadrant where cosine is positive).For cos(b): [tex]cos^2(b) = 1 - sin^2(b) = 1 - (2/5)^2 = 1 - 4/25 = 21/25[/tex]. So, cos(b) = [tex]\sqrt{(21/25)}= 4.6/5[/tex] (since b is in the first quadrant where cosine is positive).

Now, we plug these values into the formula:

sin(a+b) = (4/9)(4.6/5) + (8/9)(2/5) = 16.24/45 + 16/45 = 32.24/45

Thus, the sine of the sum of the two angles a and b is approximately 32.24/45.

I've never even seen a box and whiskers plot before!! Should be pretty straight forward though. Thanks!

Answers

For a box and whispers plot, each section represents 25% of the data. Therefore, the area from 85-99 represents 25% of the data.

25% of 24 students= 6 students
Final answer: 6 students

So a box and whiskers plot is relatively simple if you know how to do it.

The left whisker ending, which is at 35, signifies the minimum.

The right whisker ending, which is at 99, signifies the maximum.

The middle line, at 68, is the median.

And the edge of the box on the left, at 50, is the First Quartile. (If you don't know what that is, basically the marker in between the first quarter and the second quarter)

And the edge of the box on the right is the Third Quartile, (Same thing except in between the third quarter and fourth)

So since the question is asking how many students scored better than an 85, and we know that 85 is the third quartile here, we know that 1/4 of the students scored better than an 85.

(So basically each section is 1/4 of the data set)

And 1/4 of 24 is 6.

So 6 students scored better than an 85.

Let the length of the side opposite the wall be x, and the lengths of the other 2 sides be y.

y=(240-x)/2=120-x/2

The area of the rectangular enclosure is determined by the function
[tex]A(x)=x \cdot y =x \cdot (120-x/2)[/tex] (square feet)

both width and length must be >0,

so we must have:

i) x>0
ii) 120-x/2>0 (at the same time)

solving the second inequation:
