Round your answer to the nearest tenth.
Answer:
10.8
Step-by-step explanation:
using Sine Law
a/sin A = b/sin B = c/sinC
a = 8
A = 40°
b = ?
B = 120
substitute the values and you will get the answer 10.778370842670, rounding to the nearest 10ths.
10.8 is the measure of the value of x to the nearest tenth.
The sine rule formulaThe given diagram is a triangle with side 8 and angles 40 and 120 degrees.
Applying the sine rule, we will have:
x/sin120 = 8/sin40
Cross multiply to have:
8sin120 = xsin40
x = (8sin120)/sin40
x = 6.9282/0.6428
x = 10.8
Hence the measure of the value of x to the nearest tenth is 10.8.

The average of the first five multiple of 7 is
a. 7
b. 14
c. 21
d. 28
n innings In the tenth innings he sco
Answer:
b. 21
Step-by-step explanation:
The first five mutiples of 7 are: 7, 14, 21, 28, 35. You can get these by multiplying 7 to any integer.
7x1 = 77x2 = 147x3 = 217x4 = 287x5 = 35In order to get the average of these numbers, you have to add them and divide the sum to the total number of multiples.
Let's add first.
7+14+21+28+35 = 105
Let's divided 105 by 5, which is the number of the multiples of 7.
105÷5 = 21
The answer is 21.
Solve the following quadratic inequality x^2+x-6>0
Answer:
x < -3 or x > 2
Step-by-step explanation:
x² + x - 6 > 0
Convert the inequality to an equation.
x² + x - 6 = 0
Factor using the AC method and get:
(x - 2) (x + 3) = 0
If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.
x - 2 = 0
x = 2
x + 3 = 0
x = -3
So, the solution is x < -3 or x > 2

How many reflections symmetries does a decagon shaped like a five- pointed star have? How many rotational symmetries does the decagon have? Draw the reflection symmetries on the decagon.
Decagon has a total of 5 reflection symmetries
A reflection symmetry of a shape is a line that divides the shape into two halves that are mirror images of each other. To find the number of reflection symmetries of the decagon, we can draw lines through the center of the decagon that pass through pairs of opposite vertices.
We can draw a total of 5 lines through the center of the decagon that pass through pairs of opposite vertices. Each of these lines is a reflection symmetry of the decagon. Therefore, the decagon has a total of 5 reflection symmetries.
A rotational symmetry of a shape is a rotation about a fixed point that leaves the shape unchanged.
To find the number of rotational symmetries of the decagon, we can count the number of times we can rotate the decagon about its center by 36 degrees (which is the central angle of the decagon) and obtain the same shape. In this case, we can rotate the decagon about its center by 36 degrees 10 times and obtain the same shape each time.
A decagon shaped like a five-pointed star has 10 sides and 5 vertices, and it looks like this:

Pythagoras is most famous for the theorem that bears his name, the Pythagorean theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. This theorem is fundamental to the study of geometry and has applications in many fields, from architecture to physics.

Line f has a slope of -3/4 line g is perpendicular to f. What is the slope of like g
Answer:
Slope of line g = \(1\frac{1}{3}\)
Step-by-step explanation:
Line f has a slope of \(-\frac{3}{4}\) Line g is perpendicular to f* Mathematics rule: If two lines are perpendicular to each other, then the product of their slopes is equal to -1 .
∴ \(-\frac{3}{4}\) × slope of line g = -1
Slope of line g = -1 ÷ \(-\frac{3}{4}\) = 4/3 = \(1\frac{1}{3}\)
the angel of elevation from a ball on a football field to the top of a 30 foot tall goal post 16 degree 42'. How far is the football from the base of the goal post? Round to the nearest tenth of a foot.
The football is approximately 96.4 feet from the base of the goal post.
What is tangent function?The tangent function in trigonometry is used to determine the proportion between the lengths of the adjacent and opposite sides in a right triangle. Where theta is the angle of interest, the tangent function is defined as:
tan(theta) = opposing / adjacent.
When the lengths of one side and one acute angle are known, the tangent function is used to solve for the unknown lengths or angles in right triangles. In order to utilise the tangent function, we must first determine the angle of interest, name the triangle's adjacent and opposite sides in relation to that angle, and then calculate the ratio of those sides using the tangent function.
Given, the angle of elevation is 16 degrees 42'.
That is,
Angle of elevation = 16 degrees 42' = 16 + 42/60 = 16.7 degrees
Using tangent function we have:
tan(16.7) = 30/x
x = 30 / tan(16.7)
x = 96.4 feet
Hence, the football is approximately 96.4 feet from the base of the goal post.

If principal is $2,658 and rate of interest 9% then the value of the account balance is approximately $10,253 by using continuous compound interest formula.
What is the Continuous Compound Interest ?Recurring interest is interest calculated on principal plus all interest and other interest. The idea is that lenders always receive interest, not individually at specific times.
The formula for continuous compound interest :
A= Peˣⁿ

A =Amount of money after a certain amount of time
P= principal or the amount of money you start with
e =Napier's number, which is approximately 2.7183
x =Interest rate
n =Amount of time in years.
Use the continuous compound interest formula :
Given P= 2658
x =9% = = 0.09
n = 15
e = 2.7183
By using
A= Peˣⁿ
A= (2658)(2.7183)⁰°⁰⁹¹⁵

\(\sin^2(\theta)+\cos^2(\theta)=1 \implies \cos^2(\theta)=1-\sin^2(\theta)\)
Therefore,
\(\sin(\theta) \times \csc(\theta)+\cos(\frac{3 \pi}{2}-\theta)\times\sin(\theta)\)

Step-by-step explanation:
Every 3 days 1 pound of hay is used every day 1 pound of grain is used. There are 10 pounds of grain and 8 pounds of hay. On the 6th day there are 6 pounds of hay left and 6 pounds of grain left.
The number of days after which the amount of hay and the grain will be the same is 12 days.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Hay = 8 pounds
1 pound = 3 days
From the graph,
Grain = 10 pounds
5 pounds left after 10 days
1 pound = 2 days
Now,
The number of days x after which the pounds left will be the same.
(-1/3)x + 8 = 10 - (1/2)x
(-1/3)x + (1/2)x = 10 - 8
(-2x + 3x)/6 = 2
x/6 = 2
x = 12
Thus,
After 12 days the hay and the grain left over will be the same.
