The sum of the digits of certain two-digit number is 9. Reversing its digits increase the number by 45. Find the number.
A) 36
B) 30
C) 27
D) 26
If the original number can be written as ab, where a is the digits in the tens place and b is in the ones place, then it can be expanded as
10a + b
where a and b are chosen from {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}. The sum of the digits is 9, so
a + b = 9
Reversing the digits gives the number ba, or
10b + a
which is larger than ab by 45, so
10b + a = (10a + b) + 45
-9a + 9b = 45
a - b = -5
Solve for a and b :
(a + b) + (a - b) = 9 + (-5)
2a = 4
a = 2
Then
a + b = 9
2 + b = 9
b = 7
So the original number if (C) 27.
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.

hey need help fast!!!
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.

7(2+5v0=2v+14
Answer:
v=0
Step-by-step explanation:
I think you mean 7(2+5v)=2v+14.
14+35v=2v+14 distribute
33v=0 Subtract 2v and 14
v=0 divide by 33 on both sides
Hope this helps plz mark brainliest if correct :D
Suppose that Sin(θ)=5/13 and cos(θ)=-12/13. Find the value of tan(θ), cot (θ), CSC (θ), and sec (θ). Find the value of tan(2θ)
I know the values are tanθ=5/12, cscθ=13/5, secθ=13/-12 and cotθ=-12/5 but I don't know how to find tan(2θ)
Answer:
Because θ lies in quadrant II, 2θ must lie in quadrant IV. This means the tangent of 2θ is negative.
The adjacent side to θ is 7 because √(25²-24²)=7, so tanθ=7/24.
The double angle formula for tangent is tan 2θ = (2 tan θ) / (1 − tan² θ).
Substituting the value for tanθ in and keeping in mind that this is in quadrant IV, we get tan 2θ = -(2(7/24)/(1-(7/24)²)).
Simplified, this becomes tan 2θ = -336/527.
Therefore, the answer is C. -336/527.

Jemma gave 0.30 of her candy to her sister and 0.25 of her candy to her brother. How much of her candy to her brother. How much of her candy did she give away.
So, Jemma gave away 0.30 percent and also gave 0.25 away all we have to do is add these two percents and we have our answer!
0.30% + 0.25% =
0.30 plus 0.25 equals to 0.0055 so you get your answer 0.0055!
How do you write 23/25 as a percentage
Answer:
92%
Step-by-step explanation:
a Percent is equal to 1/100
so we need to make the denominator 100
so you multiply both the denominator and numerator by 4
4*23=92
4*25=100
92/100
which is also 92%
