Tyler owned the librarian late fees he had to pay a 3% fee on the cost of the books, which was $35.62. What was he charged for a late fee?

Answers

Answer:

$1.07 for the late fees.

Step-by-step explanation:

You can find the fee for this price by finding 3% of the $35.62 (total cost of the books). You can find this number by multiplying (35.62*.03).

35.62*.03

1.0686

Find the theoretical probability of rolling two cubes and getting a sum of 3.

Answers

Answer:

The theoretical probability is 1/18

Step-by-step explanation:

Firstly, we need to know the total number of possible results

By rolling two cubes, there are a total of 36 possible results

Now, the sum of 3 can be gotten by the addition of 1 to 2 or 2 to 1

If we have 1 on the first cube and 2 on the second, we have the correct sum

we can also have 2 on the first cube and 1 on the second

This gives a total of 2 possible ways of getting 3

The probability can be calculated by dividing the number of ways to get 3 by the total number of possible results

we have this simply as 2/36 = 1/18

Answers

Answer:

21y = 23

Step-by-step explanation:

1. 25y-30 = 4y-7

2. 25y-4y = 30-7 (move like terms over to each side)

3. 21y = 23

4. Approximately 1.0952381

a(b-c) = axb - axc

25y - 30 = 4y - 28

25y - 30 + 30 = 4y - 28 + 30

25y = 4y - 2

25y - 4y = 4y - 4y - 2

21y/21 = 2/21

Answers

Answer:

Step-by-step explanation:

Tyron receives a 30% discount on a hat. Calculations of discount percent are provided below.

Find the discount percentage

The discount Percentage is calculated by = [tex]( Discount / Price )[/tex] × [tex]100[/tex]

What information do we have,

Usual cost = $28

Discount = $ 8.40

So,

Discount percentage [tex]= ( 8.40 / 28 )[/tex] × 100

= 30%

Thus, 30% is the correct answer.

He distance between Miami and Naples is 107 miles. The distance between Miami and Jacksonville is about three times this distance. Landon estimates the distance between Miami and Jacksonville is about 400 miles. Is Landon's estimate reasonable? Why or why not?

Answers

Answer:

Step-by-step explanation:

Distance between Miami and Naples = 107 miles

Distance between Miami and Jacksonville is about three times this distance.

Distance between Miami and Jacksonville = 3 * 107 miles

= 321 miles

Landon estimates the distance between Miami and Jacksonville is about 400 miles

The estimate is too high

He should have estimated 107 miles to 110 miles which gives a total of 330 miles

Estimated 400 miles compared to 330 miles is too high

show all the steps for x=10x^2-2

Answers

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

x-(10*x^2-2)=0

Step-1 : Multiply the coefficient of the first term by the constant -10 • 2 = -20

Step-2 : Find two factors of -20 whose sum equals the coefficient of the middle term, which is 1 .

-20 + 1 = -19
-10 + 2 = -8
-5 + 4 = -1
-4 + 5 = 1 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -4 and 5
-10x2 - 4x + 5x + 2

Step-4 : Add up the first 2 terms, pulling out like factors :
-2x • (5x+2)
Add up the last 2 terms, pulling out common factors :
1 • (5x+2)
Step-5 : Add up the four terms of step 4 :
(-2x+1) • (5x+2)

Solve : 5x+2 = 0

Subtract 2 from both sides of the equation :
5x = -2
Divide both sides of the equation by 5:
x = -2/5 = -0.400

Solve : -2x+1 = 0

Subtract 1 from both sides of the equation :
-2x = -1
Multiply both sides of the equation by (-1) : 2x = 1


Divide both sides of the equation by 2:
x = 1/2 = 0.500

which of the at eight o'clock, which of is the angle between the hour and the minute hands

Answers

Answer:

At 8 o'clock angle between the two hands is 120 degree.

Step-by-step explanation:

For even hours, it’s easy. There are 12 numbers on the 360 degree clock face so each number is 30 degrees. Now, if you are after 6 then “the angle” is the other way so for 8:00, 12–8 = 4*30 = 120 degrees.

The problem comes in when you are not at an even hour. At, say, 8:20, the minute hand has moved 120 degrees and the hour hand has moved 1/3 of 30 or 10 degrees so, the angle is now 8*30 - 4*30 + 10 = 240 - 120 +10 = 130 degrees.

At 8:40 the minute hand has moved 8*30 = 240 degrees and the hour hand has moved 2/3 of 30 or 20 degrees so the angle is now 8*30 - 8*30 + 20 = 20 degrees

Answer:

[tex]\overline {AD}[/tex] = 5

Step-by-step explanation:

From the given diagram we are required to find the length of [tex]\overline {AD}[/tex]

The given parameters are;

ΔABC and ΔCDA are congruent

The length of [tex]\overline {BC}[/tex] = 5

The length of [tex]\overline {AC}[/tex] = 7

The length of [tex]\overline {CD}[/tex] = 4

From ΔABC ≅ ΔCDA, we have;

[tex]\overline {AC}[/tex] = [tex]\overline {AC}[/tex]  By reflexive property

∴ [tex]\overline {BC}[/tex] = 5 is either equal to [tex]\overline {AD}[/tex] or [tex]\overline {CD}[/tex]

However, [tex]\overline {CD}[/tex] = 4, therefore, [tex]\overline {BC}[/tex] ≠ [tex]\overline {CD}[/tex]

We can then have;

[tex]\overline {BC}[/tex] = [tex]\overline {AD}[/tex] = 5.

length of the hypotenuse is 7.6 centimeters. Answer parts a and b.
a. Find the length of the hypotenuse of the right triangle to the nearest tenth of a centimeter.

Answers

Answer:

41.6 centimeters

Step-by-step explanation:

The right triangle formula: c^2 = a^2 + b^2

                                  c is the hypotenuse side of the triangle

                                  a and b are the legs of the triangle.    

 Find the hypotenuse :   c^2 = (24)^2 + (34)^2

                                          c = square root of (  (24)^2 + (34)^2)

                                          c = square root of ( 576 + 1,156)

                                          c = 41.6173
