Answer:
817.71
Step-by-step explanation:
Hi!
This involves applying trigonometry.
Because we are trying to figure out the height of Burj Khalifa, we are trying to find the length of AB. We already have CB, which is the adjacent side with respect to the angle. Then, AB would be the opposite side with respect to the angle given.
Remember SOH CAH TOA? Well, we have the adjacent and opposite sides involved in this, so we use the tangent function!
It will be as follows:
tan(73) = AB / 250
AB = (250)(tan(73))
AB = 817.71 meters

Find the area of each figure and round to the nearest tenth if necessary
Answers
Given:
The figure of two semicircles with diameters 6 cm and 5 cm.
To find:
The area of the combined figure.
Solution:
It is given that the diameters of the semicircles are 6 cm and 5 cm so their radii are 3 cm and 2.5 cm respectively.
Area of a semicircle is:
[tex]A=\dfrac{1}{2}\pi r^2[/tex]
So, the combined area of two semicircles with radii 3 cm and 2.5 cm is:
[tex]Area=\dfrac{1}{2}\pi (3)^2+\dfrac{1}{2}\pi (2.5)^2[/tex]
[tex]Area=\dfrac{1}{2}\pi (9)+\dfrac{1}{2}\pi (6.25)[/tex]
[tex]Area=14.137167+9.817477[/tex]
[tex]Area=23.954644[/tex]
Round the value to the nearest tenth (one decimal place.
[tex]Area\approx 24.0[/tex]
Therefore, the area of given figure is 24.0 sq. cm.

Answers
Answer:
y = 2x + 3
Step-by-step explanation:
We need to find m and b
Let's input the first 2 points (3, 9) and (5, 13) into y = mx + b
9 = m*3 + b
13 = m*5 + b
subtract the first from the second
13 - 9 = m*5 + b - (m*3 + b)
4 = m*2
m = 2
Now let's input m = 2 into 9 = m*3 + b
9 = 2*3 + b
9 = 6 + b
3 = b
So the final relationship is y = 2x + 3
We can verify that the other two points (8, 19) and (11, 25) also conform to this relationship.

A mother bear and her cub catch fish from a river . The mother bear catch 10 fish the mother bear catch 5 times as many
Answers
Answer:
This doesn't make sense.
Step-by-step explanation:
If the question was "A mother bear and her cub catch fish from a river. The cub catches 10 fish and the mother bear catches 5 times as many as the cub. How many fish did the cub catch?" then the answer would be, The mother bear caught 50 fish.
This is because if the cub caught 10, and the mother caught 5 times that amount, the mother caught 5 x 10 fish. 5 x 10 = 50.
On one day a pet store sells 2 birds 6 gerbils 3 fish and 3 hamsters whats the data and relative frequency as a percent?
Answers
Answer:
Birds [tex]F_b=14.3\%[/tex]
Gerbils [tex]F_g=42.9\%[/tex]
Fish [tex]F_f=21.4\%[/tex]
Hamsters [tex]F_h=21.4\%[/tex]
Step-by-step explanation:
From the question we are told that:
Sales
Number of birds [tex]n_b=2[/tex]
Number of gerbils [tex]n_g=6[/tex]
Number of fish [tex]n_f=3[/tex]
Number of hamsters [tex]n_h=3[/tex]
Generally the frequency for birds [tex]F_b[/tex] is mathematically given b
[tex]F_b=\frac{n_b}{n}*100[/tex]
[tex]F_b=\frac{2}{14}*100[/tex]
[tex]F_b=14.3\%[/tex]
Generally the frequency for Gerbils [tex]F_g[/tex] is mathematically given b
[tex]F_g=\frac{n_g}{n}*100[/tex]
[tex]F_g=\frac{6}{14}*100[/tex]
[tex]F_g=42.9\%[/tex]
Generally the frequency for fish [tex]F_f[/tex] is mathematically given b
[tex]F_f=\frac{n_f}{n}*100[/tex]
[tex]F_f=\frac{3}{14}*100[/tex]
[tex]F_f=21.4\%[/tex]
Generally the frequency for fish [tex]F_h[/tex] is mathematically given b
[tex]F_h=\frac{n_h}{n}*100[/tex]
[tex]F_h=\frac{3}{14}*100[/tex]
[tex]F_h=21.4\%[/tex]

ANYONE IM RUNNING OUT OF TIME!!!!!
Answers
Answer:
Y= -5/2x+3
Step-by-step explanation:
A perpendicular slope is always opposite (meaning if the original is negative, then it is positive and vice versa) and reciprocal (meaning the numerator and denominator of the original are flipped).
The y intercept I found by applying the slope to the point given.
y = mx + b
the m represents the slope
the opposite reciprocal of 2/5 is -5/2
y = -5/2x + b
to solve the rest of the problem, you will need to plug in your x and y coordinates.
-2 = -5/2(2) + b
-2 = -10/2 + b
-2 = -5 + b
Add 5 to both sides.
b = 3
This means your equation is...
y = -5/2x + 3
