In the diagram, Triangle ABC ~ Triangle ACD. If AD = 12 and DB = 15, What is AC?
Answer:
AC = 9
Step-by-step explanation:
We solve using Pythagoras Theorem
The formula is given as:
a² + b² = c²
Where:
AC = a = ?
AD = b= 12
DB = c = 15
Hence,
a² + 12² = 15²
a² = 15² - 12²
a² = 225 - 144
a² = 81
Square root both sides
√a² = √81
a = 9
Hence, AC = 9

Eduardo mixed 5 pounds o cashews and almonds. Cashews cost $8 per pound and almonds cost $6 per pound. The total cost of the mixture was $33. How much of the mixture was almonds?
Answer:
3.5 pounds of the mixture was almonds
Step-by-step explanation:
Assume that the mixture contains x pounds of cashews and y pounds of almonds
∵ x represents the amount of cashew
∵ y represents the amount of almond
∵ Eduardo mixed 5 pounds of cashews and almonds
∴ x + y = 5 ⇒ (1)
∵ Cashews cost $8 per pound
∵ Almonds cost $6 per pound
∵ The total cost of the mixture was $33
→ Multiply x by 8 and y by 6 and equate their sum by 33
∴ 8x + 6y = 33 ⇒ (2)
Now we have a system of equations to solve it
→ Multiply equation (1) by -8 to eliminate x
∵ -8(x) + -8(y) = -8(5)
∴ -8x - 8y = -40 ⇒ (3)
→ Add equations(2) and (3)
∵ (8x + -8x) + (6y + -8y) = (33 + -40)
∴ -2y = -7
→ Divide both sides by -2
∴ y = 3.5
∵ y represents the amount of almond
∴ 3.5 pounds of the mixture was almonds
The prime factorization of 1080 is ____
.
List the factors from least to greatest and be sure to use the * between different the factors. For example, the prime factorization for 12 can be entered as 2*2*3. Do not use exponents.
Answer:
1080 = 2 * 2 * 2 * 3 * 3 * 3 * 5
Step-by-step explanation:
Start dividing by prime numbers.
1080 / 2 = 540
540 / 2 = 270
270 / 2 = 135
135 / 3 = 45
45 / 3 = 15
15 / 3 = 5
5 / 5 = 1
So we have 3 2s, 3 3s, and 1 5.

Kristin is filling 3 jars with jellybeans. If she has 1,856 jellybeans and wants to split them evenly between the jars, will Kristin have any jellybeans left over? If so, how many?
Answer:
Yes, Kristin will have 2 jelly beans left
Step-by-step explanation:
Total jelly beans = 1,856
Total jars = 3
Kristin is filling 3 jars with jellybeans
She wants to split them evenly between the jars, will Kristin have any jellybeans left over?
Jellybeans in a jar = total jellybeans / total jar
= 1,856 / 3
= 618 remainder 2
Yes, Kristin will have jelly beans left
Kristin will have 2 jellybeans left
Check:
618 × 3 = 1,854
Remaining jellybeans = 1,856 - 1,854
= 2 jellybeans

Han says that you can wrap a 5-foot rope around a wheel with a 2-foot diameter because is less than pi. Do you agree with Han? Copied for free from openupresources.Org
Given :
Han says that we can wrap a 5 foot rope around a wheel with a 2 foot rope.
To Find :
It this true or false.
Solution :
Radius of wheel, r = 1 foot.
Circumference of wheel is given by :
[tex]C = 2\pi r\\\\C = 2\times 3.14\times 1\\\\C = 6.28 \ foot[/tex]
Since, circumference is greater than 5 foot, therefore, we cannot wrap a 5-foot rope around a wheel with a 2-foot diameter.
Hence, this is the required solution.

A pair of boots are $94.99. They are 25% off. With this
discount, what is the sale price? Round to nearest
cent if necessary.
If there are 25% discount on the pair of shoes, then the sale price of boots are, $71.24
What is the sale price ?Sale price refers to the price at which a product or service is offered for sale after a discount or reduction from its original or regular price. Sale price is a promotional tool used by retailers to encourage customers to purchase products or services by offering them at a lower price than their regular price. The purpose of a sale price is to increase sales and generate revenue, as well as to clear inventory, attract new customers, and increase brand awareness. The calculation of sale price is typically performed by subtracting a certain percentage or dollar amount from the original or regular price.
Given that,
The boots are $94.99 and are 25% off,
so the discount amount is
⇒ $94.99 x 0.25 = $23.75.
The sale price of the boots is
⇒ $94.99 - $23.75
⇒ $71.24
Rounded to the nearest cent, the sale price is $71.24

A lifeguard is in an observation chair and spots a person who needs help. The angle of depression to the person is 22°. The eye level of the lifeguard is 10 feet above the ground. What is the horizontal distance between the lifeguard and the person? Round to the nearest foot.
Answer:
The horizontal distance between the lifeguard and the person is approximately 24.751 feet.
Step-by-step explanation:
At first we include a geometrical representation of the statement, which is shown in the image attached below. We can determine the horizontal distance between the lifeguard and the person by means of the following trigonometrical relationship:
[tex]\tan \theta = \frac{OL}{OP}[/tex] (1)
Where:
[tex]\theta[/tex] - Angle of depression to the person, measured in sexagesimal degrees.
[tex]OL[/tex] - Height of the lifeguard above the ground, measured in feet.
[tex]OP[/tex] - Horizontal distance between the lifeguard and the person, measured in feet.
If we know that [tex]OL = 10\,ft[/tex] and [tex]\theta = 22^{\circ}[/tex], then the horizontal distance between the lifeguard and the person is:
[tex]OP = \frac{OL}{\tan \theta}[/tex]
[tex]OP = \frac{10\,ft}{\tan 22^{\circ}}[/tex]
[tex]OP \approx 24.751\,ft[/tex]
The horizontal distance between the lifeguard and the person is approximately 24.751 feet.

If 1 droplet of water falls from a pipe every 10 seconds. How many droplets of water would have fallen 6 minutes?
Answer:
36
Step-by-step explanation:
60 seconds in one minute = 6 drops times 6 equals 36
Answer:
36 droplets of water in 6 minutes
Step-by-step explanation:
If there are 60 seconds in a minute, and one droplet of water falls in the pipe every 10 seconds then you would need to divide.
The first step is to divide 60 by 10. The answer will be 6. This means that six droplets will fall for every minute.
60/10 = 6
This gives us a unit rate to work with.
6:1 or [tex]\frac{6}{1}[/tex] or 6 droplets per minute
All you have to do is multiply.
[tex]\frac{6}{1} * 6[/tex] (the minutes)
Your answer should be 36 droplets of water have fallen into the pipe in 6 minutes.
Best of Luck!
