4.65 x 10 to the 3rd power
Answer:
(4.65 x 10)^3 = 100,544.625
Step-by-step explanation:
First, multiply 4.65 by 10
46.5
Now multiply this number by itself 3 times
46.5 x 46.5 = 2,162.25
2,162.25 x 46.5 = 100,544.625
So the answer is 100,544.625

Answer:
MN║OP
Step-by-step explanation:
From the picture attached,
MP and OP are the two lines and OT is a transversal intersecting these lines at R and S.
Angles on the same side of transversal OT measure the same as 45°
By the converse of corresponding angles theorem,
"If the corresponding angles formed by the transversal with the lines, are equal in measure, then the lines are parallel."
Therefore, MN║OP is the answer.

Let |u| = 10 at an angle of 45° and |v| = 13 at an angle of 150°, and w = u + v. What is the magnitude and direction angle of w?
a) |w| = 9.4; θ = 72.9°
b) |w| = 9.4; θ = 107.1°
c) |w| = 14.2; θ = 72.9°
d) |w| = 14.2; θ = 107.1°
Answer:
D
Step-by-step explanation:
Here, the direction angle is 107.1° and the magnitude is 14.2. Therefore, option D is the correct answer.
Given that, |u| = 10 at an angle of 45° and |v| = 13 at an angle of 150°.
We need to find magnitude and direction angle of w.
We have, w = u + v, θ=45° and ϕ=150°.
[tex]u_{x}[/tex]=|u|cosθ=10cos45°=7.071
[tex]u_{y}[/tex]=|u|sinϕ=[tex]u_{y}[/tex]=|10sin45°=7.071
[tex]v_{x}[/tex]=|v|cosθ=13cos150°=-11.25833
[tex]v_{y}[/tex]=|v|sinϕ=[tex]v_{y}[/tex]=13sin150°=6.5
Using this information, we get
[tex]R_{x} =u_{x} +v_{x}[/tex]=7.071-11.25833=-4.18733
[tex]R_{y} =u_{y} +v_{y}[/tex]=7.071+6.5=13.571
Direction angle=[tex]tan^{-1}[/tex](Ry/Rx)
Direction angle=[tex]tan^{-1}[/tex](13.571/-4.18733)
=-72.8239 or 107.1476≈107.1
Now, [tex]|w|=\sqrt{(|u|cos \theta +|v|cos \phi )^{2}+(|u|sin \theta +|v|sin \phi )^{2}}[/tex]
=[tex]|w|=\sqrt{(10cos45\textdegree +13cos150\textdegree )^{2}+(10sin 45\textdegree+13sin150\textdegree)^{2}}=14.2026[/tex]
Here, the direction angle is 107.1° and the magnitude is 14.2. Therefore, option D is the correct answer.

If ∆JKL is an equilateral triangle, JK = 13x + 5, KL = 17x – 19, and JL = 8x + 35, what is the value of x?
Answer:
x = 6
Step-by-step explanation:
Given that Δ JKL is equilateral then the 3 sides are congruent.
Equate any 2 sides and solve for x, that is
13x + 5 = 8x + 35 ( subtract 8x from both sides )
5x + 5 = 35 ( subtract 5 from both sides )
5x = 30 ( divide both sides by 5 )
x = 6
An equilateral triangle is a triangle where all three sides are equal.
The value of x is 6.
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
An equilateral triangle is a triangle where all three sides are equal.
∆JKL is an equilateral triangle.
JK = 13x + 5
KL = 17x – 19
JL = 8x + 35
Now,
JK = 13x + 5
KL = 17x – 19
JK = KL
13x + 5 = 17x - 19
5 + 19 = 17x - 13x
24 = 4x
x = 6
Thus,
The value of x is 6.

1. Mr. Jones receives 10% commission on each sale that he makes. He earned $450 last week in commissions. How much were his sales? SHOW WORK.
Given:
Rate of commission = 10% on each sale
Commission = $450
To find:
The total sales.
Solution:
Let the total sales be x. Then,
Commission = 10% of total sales
[tex]450=\dfrac{10}{100}\times x[/tex]
[tex]450=\dfrac{1}{10}\times x[/tex]
Multiply both sides by 10.
[tex]4500=x[/tex]
Therefore, the total sales is $4500.
The last week sales of Mr. Jones who receives 10% commission on each sale that he makes is $4500.
What is percentage ?Percentage of a number is the part of the number expressed in the in every hundred. Percentage of a number is expressed with the symbol '%'.
Supose Mr. Jones sold x dollar item last week. As Mr. Jones receives 10% commission on each sale that he makes and he earned $450 last week in commissions.
Thus, the 10 percent of x is equal to the $450. It can be written in expression form as,
[tex]\dfrac{10}{100}\times x=450\\x=\dfrac{45000}{10}\\x=4500[/tex]
Hence, the last week sales of Mr. Jones who receives 10% commission on each sale that he makes is $4500.
