Answer:
7. about 41.8 degrees or 0.72972 radians (used [tex]sin^{-1} (\frac{4}{6} )[/tex], because the given leg is opposite from the angle)
8. about 50.4 degrees or 0.87946 radians (used [tex]tan^{-1} (\frac{29}{24} )[/tex])
9. about 12.8 degrees or 0.224 radians (used [tex]sin^{-1} (\frac{12}{54} )[/tex])
10. about 51.3 degrees or 0.8957 radians (used [tex]cos^{-1} (\frac{25}{40} )[/tex], given leg is opposite from angle)
Step-by-step explanation:
S.O.H.--C.A.H.--T.O.A
sine = opposite (to angle)/hypotenuse
cosine = adjacent (to angle)/hypotenuse
tangent = opposite (to angle)/adjacent (to angle)
I didn't know if it was degrees or radians, so I did both! I saw you on the film question asking for help, so I just wanted to do so! Have a great day!

In a mixture of raisins and peanuts, 30% of the mixture is raisins and there 56 peanuts; how many raisins are in the mixture?
Answers
Answer: 24 raisins
Step-by-step explanation:
30% of the mixture are raisins which means that 70% are peanuts.
That 70% translates to 56 peanuts.
The total of the mixture is therefore:
= 56 / 70%
= 80 mixture of raisins and peanuts
Raisins are 30%:
= 30% * 80
= 24 raisins

Pablo is on a road trip which will cover a distance of 840 miles. He plans to break the trip up and will complete it over three days. The distances and average speeds for the first two days are shown below.Day One: 55 hours at an average speed of 66 miles per hour. Day Two: 55 hours at an average speed of 58 miles per hour. If the average speed on the third day is 55 miles per hour, how many more hours will it take for Pablo to complete his trip?
Answers
Answer: 2.87 hours
Step-by-step explanation:
There may be a typo in the question because 55 hours in a day is not logical so you must have meant 5.5 hours.
In that case, the hours he will require on the third day would require the distance left to calculate. Get this distance from the first 2 days.
Day 1 distance travelled = Time * Speed
= 5.5 * 66
= 363 miles
Day 2 distance travelled = Time * Speed
= 5.5 * 58
= 319 miles
Total distance remaining
:= 840 - 363 - 319
= 158 miles
Travelling at 55 miles per hour, the time to be taken is:
= Distance remaining / Speed
= 158 / 55
= 2.87 miles per hour

so the angle inside of the triangle equals 36 to find the one on the outside of the triangle we subtract 36 from 180
180-36 which equals 144 so 1=144

Bidet used a computer algebra system (CAS) to find the quotient of (4x^3+2x^2+3x+5)^2 and x^2+3x+1. Which statement correctly shows a way to enter this problem into a CAS?
A. Division[4x^3+2x^2+3x+5^2, x^2+3x+1]
B. Division[ (4x^3+2x^2+3x+5)^2] [x^2+3x+1]
C. Division[ (4x^3+2x^2+3x+5)^2, x^2+3x+1]
D. Division[2 (4x^3+2x^2+3x+5), x^2+3x+1]
Answers
=============================================================
Explanation:
It honestly depends on the CAS program, but for GeoGebra for instance, the general format would be Division[P, Q]
Where,
P = numerator = (4x^3+2x^2+3x+5)^2Q = denominator = x^2+3x+1As another example, let's say we want to divide x^2+5x+6 all over x^3+7 as one big fraction
We would type in Division[x^2+5x+6, x^3+7]

Sandy's dad just finished working and was paid $8000 for his work. Her dad gave her mom 5/8 of his salary to pay for household expenses. Her mom gave her brother 1/15 of the amount she received as allowances for her brother. Her brother gave Sandy 2/3 of his allowances because he owed her money. How much money did Sandy get from her brother?
a) Write an equation for this scenario
b) Solve the scenario and find out how much money Sandy got from her brother
Answers
Answer:
Sandy got (approximately) $222.22 from her brother.
Step-by-step explanation:
5/8 (8000) = 5000
1/15 (5000) = 333.33
2/3(333.33) = 222.22
5. Vernon drew an 8 in, wide by 5 in. tall picture that will be turned into a
48 ft wide billboard. How tall will the billboard be?
ACTICE ORIEM SOLVING
Answers
Answer:
The billboard should be 30 feet tall
Step-by-step explanation:
Height of the picture = 5 inches
Width of the picture = 8 inches
But the billboard has a width of 48 feet = 12 x 48
= 576 inches
To know how tall the billboard is, we have to determine the scale factor required.
scale = [tex]\frac{width of billboard}{width of picture}[/tex]
scale = [tex]\frac{576}{8}[/tex]
= 72
scale = 72
The height of the billboard = scale x 5 inches
= 72 x 5 inches
= 360 inches
Also,
The height of the billboard = [tex]\frac{360}{12}[/tex]
= 30 feet
Therefore, the billboard would be 30 feet tall.

Answers
Answer: m<C = 40
Step-by-step explanation:
Triangle angle sum theorem states that the interior angles of a triangle sum to 180. We have two angles 90 and 50. Now we need to find the third. 90+ 50 +<C = 180. 140+ C = 180. C = 40
Answer:
40
Step-by-step explanation:
sum of angle in a triangle is 180
180=90+50+c
180=140+c
180-140=c
40=c
c=40°
