Gina travels a distance of 7 miles to reach home. The bus ride covers 5 miles. She then walks 2 miles to reach her home. What fraction of miles does Gina travel by bus
Answer:
5/7 miles
Step-by-step explanation:
Gina travels a distance of 7 miles to reach home. The bus ride covers 5 Given data
Total distance traveled = 7 miles
Bus ride= 5 miles
Walk= 2 miles
Hence the fraction of miles traveled by bus is
=5/7 miles

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.

Step-by-step explanation:
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]

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.

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]

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
