Answer:
The height of the hot air balloon is 1514.54 feet approximately.
Step-by-step explanation:
Consider the provided information.
The angle of elevation from the top of a 95-foot tall building to a hot air balloon in the sky is 76. If the horizontal distance between the building and the hot air balloon is 354 feet, find the height of the hot air balloon
The figure is shown below:
Let the height of the balloon is AD, the height of the building is BC.
Draw a line BE parallel to CD.
Therefore, AD=x+95, BC=95 and BE=CD=354 ft
Now in triangle [tex]ABE[/tex].
[tex]\tan\theta=\dfrac{\text{Opp}}{\text{Adj}}[/tex]
[tex]\tan76^{\circ}=\dfrac{AE}{BE}[/tex]
[tex]AE\approx 4.01\times 354[/tex]
[tex]AE\approx 1419.54[/tex]
The height air balloon is 1419.54+95 =1514.54 ft
Hence, the height of the hot air balloon is 1514.54 feet approximately.

Answer:
MJK=90
MJL=63
JLK=63
KML=27
MNL=126
Step-by-step explanation:
If this is a perfect rectangle, then I should be correct:
Each angle of a rectangle is 90 degrees, so MJK is 90
Since we know angle KJL is 27, and MJK is 90, just subtract them to get 63.
Angle JLK should be equal to angle MJL so it is also 63
Angle KML should be equal to angle KJL so it would also be 27
And finally, angle JKN should be 27 so 27+27=54. And since all angles of a triangle add up to 180, you can get angle MNL by subtracting 180-54 to get 126 because angle MNL and JNK/KNJ are equal to each other

Which set of ordered pairs does not represent a function?
Answer: b
Step-by-step explanation: in order to be a function an input value should only have one output value. 8 has two output values ( 2 and -1 ) so it’s not a function.

40 cm is 8% of 5 m
Step-by-step explanation:
40 cm / 5m
= 40cm / 500cm
= 4/50
= 2/25
= 8%

Find the Slope
(−1, −2) , (3, −1)
Slope is equal to the change in y over the change in x, or rise over run.
change in y
m = ---------------
change in x
The change in x is equal to the difference in x-coordinates (also called run), and the change in y
is equal to the difference in y-coordinates (also called r ise).
y2 − y1
m = -----------
x2 − x1
Substitute in the values of x and y into the equation to find the s lope.
m = −1 − (−2) /3 − (−1)
Simplify the numerator.
Multiply −1 by −2.
m = −1 + 2 /3 − (−1)
Add −1 and 2.
m = 1/3 − (−1)
Simplify the denominator.
Multiply −1 by −1.
m = 1/3 + 1
Add 3 and 1.
m = 1/4

The cost before tax for an order of CDs from Music & More store was $214.60. If the store ordered 20 equally priced CDs, and the total shipping and handling fee was $15.00, what was the cost of one CD?
Answer:
Cost of one CD = $9.98
Step-by-step explanation:
Total cost = $214.60
Total shipping and handling fee = $15.00
Number of CDs = 20
Cost of 20 CDs = Total cost - Total shipping and handling fee
= $214.60 - $15.00
= $199.60
Cost of one CD = $199.60 / 20
= $9.98
Cost of one CD = $9.98
Answer:
$9.98

Triangle Deff is shown below. 110°, e, d, f, 135°
Answer:
Step-by-step explanation:
a° + 110° = 180° [Linear pair of angles]
a = 180° - 110°
a = 70°
b° + 135° = 180° [Linear pair of angles]
b = 180° - 135°
b = 45°
a + b + c = 180° [Triangle sum theorem]
45° + 70° + c = 180°
c = 180° - 115°
c = 65°
Therefore, a triangle similar to DEF will have an angle that measures 45 degrees, an angle that measures 70 degrees and an angle that measures 65 degrees.
A car travels at a speed of 55 kilometers per hour.Find the distance travelled by the car in 12 minutes and 30 seconds.Find the Answers in meters
Answer:
Step-by-step explanation:
(distance) d = (speed) s * t (time)
= 55km/h * 12.30m/s
= 11.275 km

Amy wants to buy a new set of paints. At store A, the cost is $22.00, and she has a coupon for 20% off. At store B, the cost is $22.50, and she has a coupon for $5 off. Which store has the better buy, and why?
Answer:
Store B
Step-by-step explanation:
Store A
20% is just 1/5 in percent form
22.00= 22*1/5 = 22/5 = 4.40
22.00-4.40=17.6
Store B
22.50-5=17.5
Now you can see that 17.5 is less than 17.6 by 0.1

The edges of a cube are 5 centimeters each and the diagonal of a face is approximately 7 centimeters. What is the approximate area of the cross section passing through the diagonals of opposite faces of this cube? A. 12 square centimeters B. 25 square centimeters C. 35 square centimeters D. 49 square centimeters
Answer:
C. 35 square centimeters
Step-by-step explanation:
What we need for this question:
The edges of a cube are 5 centimeters each.
The face diagonal is about 7 centimeters. (actually 7.0710678118655 cm)
To find the cross sectional area here, multiply 5 cm by 7 cm.
5 cm * 7 cm
35 cm² is your final answer, so C is the answer.
Answer:
It is C. 35 square centimeters

1. Find the slope and y-intercept of the graph of the following equation.
y=-x+4
Answer:
Slope -1 , y intersept is (0,4)
Answer:
Y intercept=4 and the slope is -1/1 or -1
Step-by-step explanation:
The numeral by itself is the Y intercept and thw number next to the x would be the slope is there is no number its just one and if its a single number for ex 4x it would be 4/1 so your answer would be Y intercept=4 and the slope is -1/1 or -1

The slope formula can be used to find the slope, m, of a line with points (L1, y1) and (22, 42).
Y2 - Yi
22 - 21
m
Which is an equivalent equation?
O Y1 = -m (22 – x1) + y2
yı = -m (x2 – 21) – Y2
Oyı = m (22 – 21) + y2
Oyı = m (22 – 21) – Y2
Answer:
A. [tex] y_1 = -m(x_2 - x_1) + y_2 [/tex]
Step-by-step explanation:
Given, slope formula = [tex] m = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
To find an equivalent equation, let's make [tex] y_1 [/tex] the subject of the formula.
[tex] m = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Cross multiply
[tex] 1(y_2 - y_1) = m(x_2 -x_1) [/tex]
[tex] y_2 - y_1 = m(x_2 - x_1) [/tex]
Subtract [tex] y_2 [/tex] from both sides
[tex] y_2 - y_1 - y_2 = m(x_2 -x_1) - y_2 [/tex]
[tex] - y_1 = m(x_2 - x_1) - y_2 [/tex]
Divide both sides by -1
[tex] \frac{- y_1}{-1} = \frac{m(x_2 -x_1) - y_2}{-1} [/tex]
[tex] y_1 = -m(x_2 - x_1) + y_2 [/tex]
