Answer:
1) From the measure of 40°, you can write:
tan(40°) = 100/x, where x is the base from the building to the tower
⇒x=100/tan(40°) = 119,18 m
2) From the measure of 30°, you can write
tan(30°) = y / 119,18, where y is the height from the roof of Jill's building to the top of the tower.
Then, y = tan(30°) * 119,18 = 68,81 m
3) The height of Jill's building is 100 - 68,81 = 31,19 m
When the height of the tower is 100 meters, the height of Jill's apartment building is 31.19m
How to calculate the height?Let the base from the building to the Rowe be represented by x. Based on the information given, the value will be:
x = 100/tan 40°
x = 119.18m
The height can be represented as:
= 100 - [tan30° × 119.18]
= 100 - 68.81
= 31.19m

A restaurant serves only tacos and enchiladas. If 60% of everyone who ate at the restaurant on a certain day ordered tacos, what percentage of those who ate at the restaurant ordered enchiladas that day
Answer:
i. 70%
ii. 70%
Step-by-step explanation:
Since in the question, it is given that 60% of everyone is ordered tacos so 40% of everyone is ordered enchiladas
i. Now if half ordered tacos that means out of these 30 orders enchiladas.
since 30 ordered tacos that means 70% ordered enchiladas
ii. Now for 3 by 4 we have to assume the number of people who ordered only enchiladas be x
So,
For both, it would be 0.75 x
And, the number of people who did not order is 40 as 60 tacos are ordered by people
So, the percentage is
= 40 × 0.75 + 40
= 30 + 40
= 70%
Two 6-sided dice are rolled. What is the probability the sum of the two numbers on the die will be 3?
Answer as a fraction = 1/18
Answer in decimal form (approximate) = 0.0556
Answer in percent form (approximate) = 5.56%
========================================================
Explanation:
We have 6*6 = 36 ways to roll out two dice. I recommend making a chart to show all the possible outcomes. You can search online for a "dice chart" or "sum of dice chart" and one will be made for you. The chart is a handy reference to see all the outcomes.
Of those 36 total outcomes, only 2 outcomes have the dice add to 3. Those two outcomes are 1+2 and 2+1.
So the number of events we want is 2 out of 36 total, meaning 2/36 = 1/18 is the probability.
Using your calculator, you should find that 1/18 = 0.0556 approximately, which converts over to 5.56% roughly.
The probability the sum of the two numbers on the die will be 3 is 5.56% roughly.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.

Answer:
76.
Step-by-step explanation:
It is given that N is a 2-digit number.
Last two digits of N^2 is the same as N.
We know that, a number is even if it ends with 0,2,4,6,8.
[tex]2^2=4,4^2=16,6^2=36,8^2=64[/tex]
If 0 is in end then we get two zeros in the square of that number.
It is clear that, number should ends with 6 to get the same number at the end.
[tex]16^2=256[/tex]
[tex]26^2=676[/tex]
[tex]36^2=1296[/tex]

A zookeeper weighed an African elephant to be 9 × 103 pounds and an African lion to be 4 × 102 pounds. How many times greater is the weight of the elephant than the weight of the lion? A. 2.25x 10 B. 5 C. 13x10 D. 3.6x10
Answer:
2.25 x 10
Step-by-step explanation:
In the above question, we were given :
The weight of the Elephant = 9 × 10³ pounds
The weight of the African Lion = 4 × 10² pounds
We would compare both weights to determine which size is bigger
Weight of Elephant : Weight of Lion
9× 10³ : 4 × 10²
= 9 × 10³/4 × 10²
= 2.25 × 10¹
= 2.25 × 10
The weight of the elephant is 2.25 × 10 times greater than the weight of the lion.

Answer:
H. 1/9.
Step-by-step explanation:
The area of a circle is calculated by solving for π[tex]r^2[/tex].
The smallest circle has an area of π[tex]1^2[/tex] = π * 1 = π.
The middle ring will then have an area of π[tex]2^2[/tex] - π = π * 4 - π = 4π - π = 3π.
The largest ring will then have an area of π[tex]3^{2}[/tex] - π[tex]2^{2}[/tex] = 9π - 4π = 5π.
5π + 3π + π = 9π
So, the probability of hitting the innermost circle will be π / 9π = 1 / 9.
Your answer is H. 1/9.

Plane A is descending toward the local airport, and plane B is ascending from the same airport. Plane A is descending at a rate of 2,500 feet per minute. Plane B is ascending at a rate of 4,000 feet per minute. If plane A is currently at an altitude of 14,000 feet and plane B is at an altitude of 1,000 feet, how long will it take them to be at the same altitude? The equation representing plane A’s descent is y = -2,500x + 14,000. The equation representing plane B’s ascent is y = 4,000x + 1,000. In both equations, y represents altitude and x represents time in minutes.
Answer: 2 minutes
Step-by-step explanation:
Given the following :
Plane A's descent :
y = -2,500x + 14,000
Plane B's Ascent :
y = 4,000x + 1,000
where y = altitude x = minute
Time to be at the same altitude :
Being at the same altitude means ;
Plane A's descent = Plane B's Ascent
-2,500x + 14,000 = 4,000x + 1,000
-2500x - 4000x = 1000 - 14000
-6500x = - 13000
x = 13000 / 6500
x = 2
x = 2minutes.

A right triangle B N O is shown with angle B marked 55 degrees, side B N marked x and side B O marked 15000 feet.
Answer:
x = 18311.61 m
Step-by-step explanation:
It is given that, An observer (O) spots a bird flying at a 55° angle from a line drawn horizontal to its nest. The distance from the observer (O) to the bird (B) is 15,000 ft. We need to find the distance between the bird and the nest. It is based on trigonometry. So,
[tex]\sin (35)=\dfrac{\text{opposite}}{\text{hypotenuse}}[/tex]
Let x is the distance between the bird and the nest
So,
[tex]\sin (55)=\dfrac{15000}{x}\\\\x=\dfrac{15000}{ \sin(55)} \\\\x=18311.61\ m[/tex]
So, the distance between the bird and the nest is 18311.61 m.

Answer:
C
Step-by-step explanation:
First, f(x) and g(x) are mirror image over the x-axis. so add a -ve in front.
Second, f(x) is about 2x steeper than g(x), that is its slope is doubled. so add a 2 in front.
Thus, f(x) = -2 g(x)

WY = x = 8
WX = y = ?
Therefore,
[tex] \frac{y}{sin(Y)} = \frac{x}{sin(X)} [/tex]

1. A rectangle measures 6 cm by
4 cm. Another rectangle with adjacent
sides o on and x cm is geometrically
similar to it.
Find the two possible value of x.
Answer:
Two figures are similar if they have the same shape:
For example, two rectangles are similar if the quotient between length and wide is the same.
Now, we know that one of the rectangles is 6cm by 4cm.
The quotient of the lengths is 6cm/4cm = 3/2
Here we have a problem; you wrote
" Another rectangle with adjacent
sides o on and x cm ....."
I guess that this means:
The other triangle has one side with a measure of x cm, and the other side will have the lenght A, a constant number that you can complete after.
Now, if this new triangle is similar to the first one, then we must have;
If x > A.
x/A = 6cm/4cm = 3/2
x = (3/2)*A.
if x < A
A/x = 6cm/4cm = 3/2
x = (2/3)*A
There you have the two possible values of x, for a known A.
