Find the area of the figure
Answer:
A = 76.912Step-by-step explanation:
Area of triangle with angle of 30°:
[tex]A_1=\frac12\cdot 5^2\cdot\sin(30^o)=\dfrac{25}4=6.25[/tex]
Area of triangle with angle of 50°:
[tex]A_2=\frac12\cdot 5^2\cdot\sin(50^o)=\dfrac{25}2\cdot0.766=9.575[/tex]
Area of the rest of the figure:
[tex]A_3=\dfrac{(360-30-50)^o}{360^o}\cdot\pi\cdot5^2=\dfrac79\cdot\pi\cdot25 =61.087[/tex]
Therefore:
[tex]A=A_1+A_2+A_3=6.25+9.575+61.087=76.912[/tex]
Smiley and Grumpy won the competition 4 years ago. This year, their jumping totals are as follows: When Smiley jumps 3 times and Grumpy jumps twice, their total is 48 step
Answer:
Smiley: 8steps
Grumpy: 12 steps
Step-by-step explanation:
Given
See attachment for complete question
Required
Steps taken by each
From the second statement, we have:
[tex]3S + 2G = 48[/tex]
and
[tex]4S + 2G = 56[/tex]
Subtract both equations
[tex]3S - 4S + 2G - 2G = 48 - 56[/tex]
[tex]-S = -8[/tex]
Solve for S
[tex]S = 8[/tex]
Substitute [tex]S = 8[/tex] in [tex]3S + 2G = 48[/tex]
[tex]3*8+2G = 48[/tex]
[tex]24+2G = 48[/tex]
Subtract 24 from both sides
[tex]2G = 24[/tex]
Divide both sides by 2
[tex]G =12[/tex]

A 25 foot ladder is placed against a building at a point 21 feet from the ground find the distance from the base of the building to the base of the ladder
Answer:
The distance from the base of the building to the base of the ladder is 13.56 feet.
Step-by-step explanation:
This can be solved using Pythagorus theorem.
If the length of the ladder is taken as the hypotenuse and the distance from the building as the base of the triangle then the altitude can be found out by using
c²= a²+b²
Where c is the hypotenuse and b is the base and a is the altitude
Putting the values
25²= a²+ 21²
a²= 25²-21²
a²= 625-441
a²= 184
a= √184= 13.56 feet
The distance from the base of the building to the base of the ladder is 13.56 feet

A helicopter is sighted at the same time by two ground observers who are 5 miles apart, both ahead of the helicopter and in its direction of travel. They report angles of elevation of 19.5° and 31.2° to the helicopter. Find the distance from the helicopter to the further observer, to the nearest tenth of a mile.
Answer:
The distance from the helicopter to the further observer is:
d = 12.77 miles
Step-by-step explanation:
The observer with 19.5° of elevation will be denoted by 1
The observer with 31.2° of elevation will be denoted by 2.
Here we have two right triangles. Both of them have the same opposite sides, so will be useful to use the tangent function.
For the second observer:
[tex]tan(31.2)=\frac{h}{x}[/tex] (1)
Where:
h is the opposite sidex is the adjacent side (distance from the observer 2 to the point where the angle of elevation is 90° )For the first observer:
[tex]tan(19.5)=\frac{h}{5+x}[/tex] (2)
Where:
h is the opposite side5+x is the adjacent side (distance from the observer 1 to the 90° elevation point, 5 miles is the distance between observes )Let's find x from equations (1) and (2). Both of them have the variable "h" so we can equal these equations.
[tex]xtan(31.2)=(5+x)tan(19.5)[/tex]
[tex]x(tan(31.2)-tan(19.5))=5tan(19.5)[/tex]
[tex]x=\frac{5tan(19.5)}{tan(31.2)-tan(19.5)}[/tex]
[tex]x=7.04\: miles[/tex]
Now, if we use the right triangle with 19.5° of elevation, the hypotenuse will be the distance from the helicopter and the further observer (let's call d).
Let's use the cosine function to find d.
[tex]cos(19.5^{\cric})=\frac{5+x}{d}[/tex]
[tex]d=\frac{5+7.04}{cos(19.5^{\cric})}[/tex]
[tex]d=12.77\: miles[/tex]

1. Find the diameter of the circle.
9 in.
PLEASEEEEE HELPPPPPPPP
Answer:
142.5
Step-by-step explanation:
It is 142.5 because when finding area you have to do base x height our base here is 15 and are height is 9.5 so now that we know are base and height we just multiply! so 15 × 9.5 = 142.5 Hope this helps!

Complete the table and then graph the following exponential function.
() = (3)x
let f(x) = 6x^2 + 5 and g(x) = 3x-5. find f(g(7))
Answer:
let f(x) = 6x^2 + 5 and g(x) = 3x-5.
f(g(x))=f(3x-5)=6(3x-5)²+5=6(9x²-30x+25)-5
=54x²-180x+150-5=54x²-180x+145
again
f(g(7))=54×7²-180×7+145
=1531 is your answer

Armando took his dog, Tasha, to the vet. Tasha was placed on the scale and weighed 45.72 pounds. The veterinarian told Armando that Tasha’s breed should weigh no more than Thirty-six and one-half pounds. Armando calculated about how much weight Tasha should lose to be under the breed’s maximum weight. 45.72 rounds to 45 rounds to 37 45 – 37 = 8 pounds Which statements are true about Armando’s calculations? Check all that apply. Armando should have added 37 to 45. Armando should have rounded 45.72 to 45.5. Armando should not have rounded Thirty-six and one-half to 37. Armando should have calculated that the difference between 45 and 37 is 7. Armando’s last step should have shown 45.5 Minus thirty-six and one-half = 9.

Given the spinner below, the
probability of landing on an
A is . Predict how many times you would land on an A if you spun the spinner 24 times
A. 8
B. 9
C. 10
D. 12
Answer:
B. 9
Step-by-step explanation:
The probability of landing on A is 3/8. Now, multiply the fraction by the number of times it will be spun.
3/8 × 24 = 9
Hope this helps!
Answer:
9 times
Step-by-step explanation:
Probability for landing on A is 3/8. So, for every 8 times you spin, you predict that you will land on A 3 times (3 times out of 8 spins).
So you either
A.) multiply the probability by the total spins:
(3/8) * (24) = 9 times you land on A
or
B.) divide the 24 spins by 8, to get 3 different repeats of the probability.
So 3 * 3 = 9 times.
