Answer:
Step-by-step explanation:
in 10 hrs distance covered=speed×time=15×10=150 nautical miles.
x²=600²+150²-2×600×150×cos 20°
x²=360,000+22,500-180,000×cos 20°
x=√(382,500+180,000×cos 20°)
x\approx 742.73 nautical miles
time taken=742.73/15 \approx ~49.52 hours
total time taken=10+49.52=59.52 hours
applying sine formula
[tex]\frac{sin ~B}{150} =\frac{sin~20}{742.73} \\\sin~B=\frac{150}{742.73} \times~sin~20\\B=\sin^{-1} [\frac{150}{742.73} \times \sin~20]\\B\approx~3.96 ^\circ\\B\approx 4^\circ[/tex]
so it has to make a turn=20+4=24°

Tyler has to figure out the amount of metal to cover the back of the shelves in Mrs. Edwards room. These are the dimensions. What is the amount of metal he will need to cover the back of the shelves?
210 square inches
108 square inches
180 square inches
36 square inches
Answers
The amount of metal he will need to cover the back of the shelves is 180 inches².
The figure above is like a composite figure. Therefore, lets find the area.
Area of the composite figureThe area of the figure is the sum of the whole individual 2 dimensional shapes in the composite figure.
Therefore, two rectangles can be drawn from it.
area of rectangle = lw
where
l = length
w = width
Therefore,
area of rectangle 1 = 9 × 8 = 72 inches²
area of rectangle 2 = 6 × 18 = 108 inches²
Total area = 108 + 72 = 180 inches²
Therefore, the amount of metal he will need to cover the back of the shelves is 180 inches².

14. 4
7. 2. 2. 2
Answer:
Spot 1: 14
Spot 2: 7
Step-by-step explanation:
To fill in the first empty spot, we just have to look at the other side.
We can see that the factor on the right is 4
That means the factor on the left has to multiply by 4 to get 56
To find which number that is, we divide 56 by 4
56 ÷ 4 = 14
So, the first spot is 14
Then, to find the spot below it, we need a number that multiplies by 2 to get 14
Well, 14 ÷ 2 = 7
The second spot is 7

Use the properties of logarithms to expand the logarithm as much as possible. Rewrite the expression as a sum, difference, or product of logs.
log(x3y−8−−−−−−√)
Answers
Answer:
You are multiplying two factors in the argument. So we add the logs.
log(x4y3) + log((x2y5)1/3)
log(x4y3) + log(x2/3y5/3)
For each log term. The arguments are being multiplied. So we further add the logs. Also, any exponents become of the coefficients of logs.
4log(x) + 3log(y) + (2/3)log(x) + (5/3)log(y)
Combine like log terms.
(14/3)log(x) + (14/3)log(y)

2. A father offers three portions of his crop land to his daughter for a corn maze. All
portions are circular and the daughter can only choose one portion. The first
portion has an 875 feet radius. The second portion has a 1715 feet diameter. The
third portion has a 5305 feet circumference. The daughter does not want more
than 2,250,000 square feet of corn maze. Which of the portions will be chosen by
the daughter?
Answers
If the daughter does not want more than 2,250,000 square feet of the corn maze, hence she will choose all the portions
Circumference and area of circlesThe formula for calculating the area of circle is expressed as;
A = πr²
r is the radius of the circle
If r = 875ft
A = 3.14(875)²
A = 2,404,062.5squar feet
For the diameter = 1715feet
r = 1715/2
A = 3.14(1715/2)²
A =2,308,861.625 square feet
For the third portion has a 5305 feet circumference;
5305 = 2(3.14)r
r = 844.74ft
A = 3.14(844.74)^2
A = 2,240,686.70
If the daughter does not want more than 2,250,000 square feet of the corn maze, hence she will choose all the portions

The dot plot states that:
2 students have 4 vowels in their first and last name.
3 students have 5 vowels.
8 students have 6 vowels.
9 students have 7 vowels.
Then:
Total of 2 + 3 + 8 + 9 = 22 students.

x = length of the actual car in inches
5% of x = 9 inches
0.05x = 9
x = 9/(0.05)
x = 180 inches
