Answer:
The monument is approximately 86.6 feet tall
Step-by-step explanation:
The given monument parameters are;
The distance of the person from the monument = 50 feet
The angle of depression from the top of the monument to the person's feet = 64°
Given that the angle of elevation to the top of the monument from the person's feet = The angle of depression from the top of the monument to the person's feet, we have;
tan(Angle of depression) = tan(Angle of elevation) = (The height of the monument)/(The distance from the monument)
∴ The height of the monument = tan(Angle of depression) × The distance from the monument
Substituting the known values, gives;
The height of the monument = tan(60°) × 50 ≈ 86.6
The height of the monument ≈ 86.6 feet.

Answer:
Mei earn $2 less than three times as much as Olivia. Shane earns twice as much as mei. Together they earn $594 per week. How much does each person earn per week?
***
Step-by-step explanation:
let x=amt Olivia earns
3x-2=amt Mei earns ($2 less than three times as much as Olivia).
2(3x-2)=amt Shane earns (twice as much as mei)
..
x+3x-2+2(3x-2)=594
x+3x-2+6x-4=594
10x=600
x=60
3x-2=178
2(3x-2)=356
amt Olivia earns=$60
amt Mei earns=$178
amt Shane earns=$356

Step-by-step explanation:
If we accept that the left side of the left triangle corresponds to the left side of the right triangle, then the scale factor is 6/8 = 3/4. By multiplying the scale factor by the bottom side of the first triangle, you'll get the corresponding side of the right triangle: 20 * 3/4 = 15.

Answer:
Question 2: v = 25n
Question 3: b (the output is 250 because 10 quarters is 250 cents)
Step-by-step explanation:
Each quarter is worth 25 cents. n represents the number of quarters you have. The number of quarters you have multiplied by 25 with give the value of the quarters in cents.
v = 25n
v = 25(10)
v = 250
(v represents the value in cents)

Answer:
A) y = -1/2x + 2
Step-by-step explanation:
The line is negative, so you will have a negative slope
The line is crossing the y- axis at 2 so the y- intercept is 2.
Now do rise over run or rise/run
The lines rise is 2 and the run is 4
2/4 = 1/2 and since the line is negative the slope is negative -1/2
y = -1/2x + 2

The Vanderbloom family already traveled 200 miles on their vacation. The total distance that they will travel (d) is a function of their rate of travel (r) and their upcoming travel time (t).
Answer:
See explanation
Step-by-step explanation:
The question is incomplete. However, I'll ask and answer possible questions that emanate from the given parameter.
A possible question is: Write the given information as a function of distance.
We have that;
[tex]Base\ Distance = 200[/tex]
[tex]Time = t[/tex]
[tex]Rate = r[/tex]
The function would be calculated as:
Base Distance + Rate * Time
Substitute values for Base Distance, Rate and Time
This gives:
[tex]200 + r * t[/tex]
[tex]200 + rt[/tex]
Hence;
[tex]Distance = 200 + rt[/tex]
Another possible question is to determine the current distance travelled by the family at a rate of 80 miles per hour for 3 hours.
Here, we have:
[tex]r = 80[/tex]
[tex]t = 3[/tex]
Substitute these values in [tex]Function = 200 + rt[/tex]
[tex]Distance = 200 + 80 * 3[/tex]
[tex]Distance = 200 + 240[/tex]
[tex]Distance = 440[/tex]
1. The base of an open rectangular tank is 3.2 m by 2.8 m. Its height is 2.4 m. It contains
water to a depth of 1.8 m. Cal culate the surface area inside the tank that is not in conta
with water.
Answer:
16.64 m
Step-by-step explanation:
Subtract the depth of the water from the height of the tank (0.6) and use this measurement for height instead. then calculate l•h•2+w•h•2+l•w
(we multiplied the length and height and the width and height by two since there’s two sides with the same measurement for each)
In 3 hours Traci is 135 miles from home as she drives from San Francisco to Dawson. Let represent the number of hours and represent the number of miles. The rate of change is and in 12 hours Traci will be miles from home
Answer:
45 mph
540 miles
Step-by-step explanation:
Given that :
Number of miles from home = 135 miles
Number of hours = 3 hours
Rate of change : Distance / Time
Rate of change = 135 miles / 3 hours
Rate of change = 45 miles per hour
Distance covered in 12 hours :
45 mph * 12 hours = 540 miles
Hence, In 12 hours Traci will be 540 miles from home

Margo is selling boxes of nuts to raise money for her club. She finds that 3 out of every 7 boxes of nuts are cashews. Write a ratio to represent the number of boxes of cashews to the total number of boxes sold.
Answer:
3 : 7
Step-by-step explanation:
make sure the three of on the left
The number of boxes of cashews to the total number of boxes sold is expressed as 3:7 in ratio.
What is Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other. The general form of expressing a ratio between two quantities say 'a' and 'b' is a: b
Margo finds that 3 out of every 7 boxes of nuts are cashews.
In order to calculate the ratio of two quantities, we can use the following steps
First, we must determine the quantities for both scenarios for which we are calculating the ratio. In this situation, there are three cashews and seven boxes.
Write it as a fraction, a/b. As a result, we write it as 3/7.
Therefore, the number of boxes of cashews to the total number of boxes sold is expressed as 3:7 in ratio.

Marc mixes blue and yellow paint to make his favorite shade of green, which he'll use to paint his house. He has 14 cans of blue paint and 20 cans of yellow paint when he starts. He wants the same green color every time he mixes, so the amounts of blue and yellow must always be proportional to the original mixture. On day 1, he mixes 4 cans of blue and 6 cans of yellow. On day 2, he mixes 6 cans of blue and 9 cans of yellow. Fill in the blanks to find the highest number of cans of each color Marc can mix to make the same shade of green on day 3. 1. In simplest form, what is the ratio of blue paint to yellow paint in the mixture?
Answer:
2 : 3
Step-by-step explanation:
Total cans of blue paint = 14
Total cans of yellow paint = 20
Day 1:
Yellow paint = 6 cans
Blue paint = 4 cans
Ratio of blue paints to yellow paint
4 cans : 6 cans
= 2 : 3
Day 2:
Yellow paint = 9 cans
Blue paint = 6 cans
Ratio of blue paints to yellow paint
6 cans : 9 cans
2 : 3
The ratio of blue paint to yellow paint in the mixture is 2 : 3
Day 3:
Cans of yellow remaining after 2 days
Yellow paint = Total cans of yellow paint - day 1 cans of yellow paint - day 2 cans of yellow paint
= 20 - 6 - 9
= 20 - 15
= 5 cans
Cans of blue remaining after 2 days
Blue paint = Total cans of blue paint - day 1 cans of blue paint - day 2 cans of blue paint
= 14 - 4 - 6
= 14 - 10
= 4 cans
An item is regularly priced at $81. It is on sale for 45% off the regular price. Find the sale price.
Answer:
44.55
Step-by-step explanation:
Internet said this: "Thus, a product that normally costs $ 81 with a 45 percent discount will cost you $ 44.55, and you saved $ 36.45. You can also calculate how much you save by simply moving the period in 45.00 percent two spaces to the left, and then multiply the result by $ 81 as follows: $ 81 x. 45 = $ 36.45 savings."
