A bookstore bought a case of 10 books at a wholesale price of $84. The bookstore will sell the books at a 25 percent
markup, and each book will be sold for the same amount. How much will they sell each book in the case for?
O $8.40
O $10.50
O $105.00
O $105.80
Answer:
$ 8.40
Step-by-step explanation:
divide 84 by 10 and you will get $8.40.
To find how much they bought each book for, you must divide by 10. 74 divided by 10 is 7.4. Then if they are selling them for 20% more, then multiply 7.4 and 1.2
Your answer is $8.80

Two 6-sided dice are rolled. What is the probability that the sum of the two numbers of the dice will be less than 6?
Answer:
I believe it would just be 5/6.
Step-by-step explanation:
In a six-sided dice, there are five numbers less than 6!
Step-by-step explanation:
sum of dice=1+2+3+4+5+6=21
sum of two sided dice=21(2)=42
sum of numbers less than 6=1+2+3+4+5=15
probability of two numbers less than 6=2/12=1/6

Answer:
A = 51° b = 15.3858... c = 24.448
Step-by-step explanation:
Given: B= 39°
a = 19
and that it's a right triangle
so that means the other 3rd angle is
A+39+90=180
A= 51°
use SOH CAH TOA to remember how sin cos and tan fit on the triangle
Sin(x)=Opp/Hyp Cos(x)=Adj/Hyp Tan(x)=Opp/Adj
Let's use Tan to find b
Tan(b) = Opp / Adj
Tan(39) = b / 19
19*Tan(39) = b
15.38589... = b
use Pythagoras to find c
c = [tex]\sqrt{a^{2} +b^{2} }[/tex]
c = [tex]\sqrt{19^{2} +15.3858^{2} }[/tex]
c = 24.448....

The local school board wants to get parents to evaluate teachers. They select 100 parents and find that 89% approve of their child’s teacher
Answer:
Ok? Did you finished asking the question? Just in case, that is 89/100 or 0.89
Step-by-step explanation:
Here, Population: All parents, Sample: 100 parents and Parameter: Parents’ approval of teachers
What is sample space in probability?The sample space of a random experiment is the collection of all possible outcomes. An event associated with a random experiment is a subset of the sample space. The probability of any outcome is a number between 0 and 1. The probabilities of all the outcomes add up to 1.
Given that, A local school board wants to get parents to evaluate teachers. They select 100 parents and find that 89% approve of their child’s teacher, here we need to find the population, sample and parameter of interest
So, as we see,
The population is the entire group that you want to draw conclusions about.
Therefore, the population here is = All parents
The sample is the specific group that you will collect data from.
Therefore, the sample = 100
The parameter is any characteristic that can help in defining or classifying a particular system.
Therefore, the parameter = Parents’ approval of teachers
Hence, we get Population: All parents, Sample: 100 parents and Parameter: Parents’ approval of teachers

Use a pythagorean triple to the lengths of the hypotenuse of a right triangle if the legs have lengths of 20 units and 48 units
Answer:
52 units.
Step-by-step explanation:
Use the Triple 5-12-13
20 / 4 = 5
48/ 4 = 12
So the hypotenuse = 4 * 13 = 52.
The lengths of Hypotenuse 52 units.
What is Pythagoras Theorem?The Pythagoras theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares.
According to the Pythagoras theorem, the square of the hypotenuse of a triangle, which has a straight angle of 90 degrees, equals the sum of the squares of the other two sides.
Given:
The measurement of two sides are 20 units and 48 units.
Now, Using Pythagoras theorem
H² = P² + B²
H² = 20² + 48²
H² = 400 + 2304
H² = 2704
H = 52 units.
Hence, lengths of Hypotenuse 52 units.

From his house, Tristan could drive due north to get to his parents' house or he could drive due east to get to his grandparents' house. It is 6 miles from Tristan's house to his parents' house and a straight-line distance of 6.4 miles from his parents' house to his grandparents' house. How far is Tristan from his grandparents' house? If necessary, round to the nearest tenth.
Answer:
[tex]TG = 2.2[/tex]
Step-by-step explanation:
Represent Tristan's house with T, his grandparent's with G and his parents with P.
Such that:
[tex]TP = 6[/tex]
[tex]GP = 6.4[/tex]
Required
Find TG
To solve this, we make use of Pythagoras Theorem which is represented as:
[tex]GP^2 = TP^2 + TG^2[/tex]
Substitute values for GP and TP
[tex]6.4^2 = 6^2 + TG^2[/tex]
[tex]40.96 = 36 + TG^2[/tex]
Collect Like Terms
[tex]TG^2 = 40.96 - 36[/tex]
[tex]TG^2 = 4.96[/tex]
[tex]TG = \sqrt{4.96[/tex]
[tex]TG = 2.2[/tex] --- Approximated
Hence, the distance between Tristan ans his grandparent's house is 2.2 miles

if you were to make a restaurant, and need 29 items, how much of each would you have?
Answer:
3 beverages, 5 appetizers, 8 entrees, and 4 desserts.
Step-by-step explanation:
I think you meant 20 items, so let's do that. To find 15% of 20, we multiply 20 by .15. This gets us 3. We repeat this with all the other numbers, using different decimals, of course. We get 3 beverages, 5 appetizers, 8 entrees, and 4 desserts. 3 + 5 + 8 + 4 is 20, so everything checks out.

7. Slips are drawn form a box containing 100 slips written with numbers 1 to 100. If three slips are
drawn one after the another with replacement, then the probability that first slip bears an even
number, second bears an odd number, third bears a perfect square number, is
a)1/100
b)1/25
c)1/45
d)1/40
Answer:
D
Step-by-step explanation:
We need the numbers of each before we can calculate the probability
Number of even numbers are 50
Number of odd numbers are 50
Number of perfect squares;
1 , 4 , 9 , 16 , 25 , 36 , 49 , 64 , 81 and 100
10 perfect squares
Probability of selecting even = probability of selecting odd = 50/100 = 1/2
Probability of selecting a perfect square = 10/100 = 1/10
Thus, the probability of having the draws in the other stated in the question will be;
1/2 * 1/2 * 1/10 = 1/40

its given that x varies directly with y square and x=3 and y=3.Find the value of x when y=45
Step-by-step explanation:
x = ky², where k is a real constant.
When x = 3, y = 3.
=> 3 = 9k, k = 1/3.
Therefore x = y²/3.
When y = 45, x = 45²/3 = 675.
