Answer: 10 books
Step-by-step explanation:
Let the number of books bought be represented by x.
Let the number of dvds bought be represented by y.
The information given in the question can be formed into an equation as:
x + y = 18 ........ i
0.50x + 0.75y = 11 ....... ii
Multiply equation i by 0.75
Multiply equation ii by 1
0.75x + 0.75y = 13.50 ........ iii
0.50x + 0.75y = 11 ........ iv
Subtract iv from iii
0.25x = 2.50
x = 2.50/0.25
x = 10

Answer:
x = 1.5
Step-by-step explanation:
Based in the tangent-secant theorem,
KI*JI = HI²
KI = (x + 0.5)
JI = 0.5
HI = 1
Plug in the values
(x + 0.5)(0.5) = 1²
0.5x + 0.25 = 1
0.5x = 1 - 0.25
0.5x = 0.75
x = 0.75/0.5
x = 1.5

Mr. Wedmore works at a car dealership and earns
a monthly salary of $2,000. He also earns 25%
commission on the gross profit of the car sales. If
Mr. Wedmore brought in $10,000 worth of profit
for the dealership, how much would he earn this
month?
Answer: $2,000. + 25% + $10,000= 12,500 Or $2,000. - 25% - $10,000=8500
Step-by-step explanation:
Answer: $4,500
Step-by-step explanation: First, the monthly salary is $2,000 so this is part of the total already. The 25% commission is on the profit they earn and the profit they earned was $10,000. To find 25% of $10,000, you do 10,000 times 0.25 which is $2,500.
Total Earned: $2,000 (Monthly Salary) + $2,500 (Commission Amount) = $4,500

Intr un album numarul de fotografii s a micsorat cu 50%. Cu cat trebuie sa se mareasca pentru a reveni la numarul initial? Raspunsul trebuie sa fie 100%.
Răspuns:
100%
Explicație pas cu pas:
Permiteți numărul inițial de fotografii = x
x - 50% din x = x - 0,5x = 0,5x
0,5x + câte% din 0,5x = x
x - 0,5x = y% de 0,5x
0,5x / 0,5x = 1
Prin urmare,
100% = 1
Prin urmare, x trebuie mărit cu 100% pentru a reveni la numărul original.
A 45 foot ladder is set against the side of a house so that it reaches up 27 feet. If Latanya grabs the ladder at its base and pulls it 3 feet farther from the house, how far up the side of the house will the ladder reach now? (The answer is not 24 ft.) Round to the nearest tenth of a foot.
Answer:
22.4 ft
Step-by-step explanation:
The side of the ladder from the house will be 22.4 ft far.
What is the Pythagorean theorem?Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal to the square of the sum of the other two sides. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.
Given that a 45-foot ladder is set against the side of a house so that it reaches up to 27 feet. If Latanya grabs the ladder at its base and pulls it 3 feet farther from the house.
The distance will be calculated as,
a² + b² = c²
a² + (39)² = 45²
a² = 45² - 39²
a=√504
a = 22.4 ft
Therefore, the side of the ladder from the house will be 22.4 ft far.

A water sprinkler sends water out in a circular pattern. How many feet away from the sprinkler can it spread water if the area formed by the watering pattern is 1256.00 square feet? Use 3.14 for pi
Answer:
20 feet
Step-by-step explanation:
A water sprinkler sends water out in a circular pattern. How many feet away from the sprinkler can it spread water if the area formed by the watering pattern is 1256.00 square feet? Use 3.14 for pi
From the above question, we are to find the radius of the circular pattern
The formula for the Area of the circle = πr²
To find r
r² = A/π
r = √A/π
In the above question, Area = 1256 square feet
π = 3.14
r = √1256/3.14
r = √400
r = 20 feet
The radius/distance from the sprinkler that can spread water = 20 feet
You are planning a backpacking trip. You must hike a minimum of 11 miles each day in order to complete the trip in the time you have available. Write an inequality to represent the situation. Let x represent the number of miles you must hike each day.
Answer:
x≥11
Step-by-step explanation:
The information provided indicates that you have to hike minimum 11 miles each day to be able to complete the trip in the time you have and this means that the number of miles you hike each day has to be greater than or equal to 11 and this can be expressed as:
x≥11, where:
x is the number of miles you must hike each day.

Answer:
The number of tickets purchased typically varies from the expected value by 0.95 tickets.
Step-by-step explanation:
The standard deviation of the distribution is 0.95.
What is Standard Deviation?The standard deviation in statistics is a measure of the amount of variation or dispersion in a set of values. A low standard deviation implies that the values are close to the set's mean, whereas a high standard deviation shows that the values are spread out over a larger range.
We have
P (X = 1)= 0.29
P (X = 2) = 0.44
P( X= 3) = 0.19
P (X = 4) = 0.06
P (X = 5) = 0.02
The expected value is given by the sum of each value multiplied by it's respective probability, hence:
E(X) = 0.29(1) + 0.44(2) + 0.19(3) + 0.06(4) + 0.02 (5)
E(X) = 2.08
As, The standard deviation is the square root of the total of the difference squared between each value and the mean, multiplied by the likelihood of each value.
[tex]\sigma[/tex] = √0.29 (1- 2.08)² + 0.44(2- 2.08)² +.....+ 0.02 (5- 2.08)²
= 0.95
Thus, the standard deviation is 0.95.
