What is tangent of an angle?The tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side.
What is sine of an angle?The sine (sin) of an acute angle in a right angled triangle is the ratio between the side opposite the angle and the hypotenuse of the triangle.
According to the given question.
We have a right angled triangle.
In which one angle is 44 degrees and hypotenuse is 17 units.
Here,
With respect to angle 44 degrees the adjacent side is x and the opposite side is y.
Therefore,
Sine of 44 degrees is given by
[tex]sin44^{o} = \frac{opposite\ side }{Hypotenuse}[/tex]
[tex]\implies sin44^{o} = \frac{y }{17}[/tex]
[tex]\implies 0.6946 = \frac{y}{17}[/tex]
[tex]\implies 0.6946 \times 17 = y[/tex]
[tex]\implies y = 11.80[/tex]
[tex]\implies y = 11.8[/tex]
And, tangent of 44 degrees is give by
[tex]tan 44^{o} = \frac{opposite \ side }{adjacent \ side }[/tex]
[tex]\implies tan44^{o} = \frac{y}{x}[/tex]
[tex]\implies tan44^{o} = \frac{11.8}{x}[/tex]
[tex]\implies 0.9657 = \frac{11.8}{x}[/tex]
[tex]\implies x = \frac{11.8}{0.9657}[/tex]
[tex]\implies x = 12.22[/tex]
[tex]\implies x = 12.2[/tex]
Therefore, the value of x and y is 12.2 and 11.8 respectively.

Aubrey is going to invest $160 and leave it in an account for 7 years. Assuming the interest is compounded daily, what interest rate, to the nearest tenth of a percent, would be required in order for Aubrey to end up with $220?
Answer:
4.5%
Step-by-step explanation:
compound interest formula:
[tex]PV(1+\frac{i}{n})^{t*n}[/tex]
[tex]220=160(1+\frac{x}{365})^{365*7}\\\\1.375=(1+\frac{x}{365})^{2555}\\1.0001246=1+\frac{x}{365}\\x=.0454962254126[/tex]
this rounds to
x=4.5%
Aubrey would need an interest rate of 6.3%.
What is compound interest?It is the interest we earned on the interest.
The formula for the amount earned with compound interest after n years is given as:
A = P [tex](1 + r/n)^{nt}[/tex]
P = principal
R = rate
t = time in years
n = number of times compounded in a year.
We have,
A = P [tex](1 + r/n)^{nt}[/tex]
A = the final amount (in this case, $220)
P = the initial investment (in this case, $160)
r = the interest rate (what we are trying to find)
n = the number of times the interest is compounded per year (since it's compounded daily, n = 365)
t = the time period (in years, in this case, 7)
Substituting in the given values and solving for r:
220 = 160(1 + r/365)^(3657)
220/160 = (1 + r/365)^(3657)
1.375 = (1 + r/365)^2555
ln(1.375) = 2555 ln(1 + r/365)
ln(1 + r/365) = ln(1.375)/2555
1 + r/365 = e^(ln(1.375)/2555)
r/365 = e^(ln(1.375)/2555) - 1
r = 365(e^(ln(1.375)/2555) - 1)
r ≈ 6.3%
Therefore,
Aubrey would need an interest rate of 6.3%.

The hypotenuse in this 45-45-90 triangle is given. How would you find the length of a leg
of the triangle?
8 V2
45degrees
Answer:
The length of the legs of the triangle is 8 units.
Step-by-step explanation:
45-45-90 triangle
A 45-45-90 triangle is a special case of a right triangle in which both legs l have the same value and the hypothenuse is h. By the Pythagorean Theorem:
[tex]2l^2 = h^2[/tex]
Hypothenuse of 8 V2
This means that [tex]h = 8\sqrt{2}[/tex]
So
[tex]2l^2 = h^2[/tex]
[tex]2l^2 = (8\sqrt{2})^2[/tex]
[tex]2l^2 = 64*2[/tex]
[tex]l^2 = 64[/tex]
[tex]l = \sqrt{64}[/tex]
[tex]l = 8[/tex]
The length of the legs of the triangle is 8 units.

James has a mass of 32.8 kg. Ricardo's mass is 8 3/4 kg more than James's. Winthorp's mass is 3.6 kg less than Ricardo's. What is the total mass of the three boys?
Answer:79.5
Step-by-step explanation:32.8+8.75=41.55 41.55-3.6=37.95 37.95+41.55+32.8=79.5
111.94 kg is the total mass of the three boys.
What is ratio?An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. An equation with two ratios set equal to one another is called a percentage.
given, James has a mass of 32.8 kg. Ricardo's mass is 8 3/4 kg more than James's. Winthrop's mass is 3.6 kg less than Ricardo's.
Since Mass of James = 32.8 kg
thus Mass of Ricardo = [tex]8\frac{3}{4}[/tex] + 32.8 = 41.55kg
And Mass of Winthrop = 41.55 - 3.6 = 37.59kg
Sum of mass of all three boys = 32.8 + 41.55+ 37.59
Sum of the mass of all three boys = 111.94 kg
Therefore, the Total mass of the three boys is 111.94 kg.

Step-by-step explanation:
Formulas for a cube:
The volume of a cube:
V = a3
The surface area of a cube:
the area of each face (a x a) times 6 faces
S = 6a2
Face diagonal of a cube:
By the Pythagorean theorem, we know that
f2 = a2 + a2
Then f2 = 2a2
solving for f we get
f = a√2
Diagonal of the solid cube:
Again, by the Pythagorean theorem, we know that
d2 = a2 + f2
substituting f into this equation we get
d2 = a2 + (a√2)2 = a2 + 2a2 = 3a2
solving for d we get
d = a√3

Answer:
[tex]x + y \ge 10[/tex]
[tex]x + 2y \le 20[/tex]
Step-by-step explanation:
The question is incomplete as the graphs are not shown. So, I will derive the inequalities and plot the graph.
Given
[tex]Banana = \$1[/tex]
[tex]Orange = \$ 2[/tex]
[tex]Purchase = 10lb[/tex] --- At least
[tex]Spedings = \$20[/tex] --- Not more than
And we have:
[tex]x = Banana; y = Orange[/tex]
The number of purchase will be represented as:
[tex]x + y \ge Purchase[/tex] ---- (at least)
[tex]x + y \ge 10[/tex]
The amount spent will be represented as;
[tex]1 * x + 2 * y \le 20[/tex] --- (not more than)
[tex]x + 2y \le 20[/tex]
So, the inequalities are:
[tex]x + y \ge 10[/tex]
[tex]x + 2y \le 20[/tex]

Answer:
B. 36π in²
Step-by-step explanation:
Given:
Volume = 54π in³
height (h) = 6 in.
Required:
Curved surface area of the can (area for the label needed to wrap around the can without overlapping)
Solution:
First, we need to find the radius (r) of the can.
Volume = πr²h
Plug in the given values and solve for r
54π = π*r²*6
54π = 6π*r²
54π/6π = r²
9 = r²
r = √9
r = 3 in
✔️Find the curved surface area:
Curved surface area = 2πrh
r = 3 in
h = 6 in
Plug in the values
C.S.A = 2*π*3*6
C.S.A = 36π in²

x+2y=6
since x is similar in both equations you cancel it out
subtract this
3y=7.25
2y=6
y=$1.25(price for 1 muffin)since we had 3 muffins it will be 1.25×3=7.25,where you do 7.25 to get 3.5 (price for 1 bagel)question 8:ticket(x)

6x+8y=70
eliminate x
y=2
so snack is $2
2x+(3×2)=24

Step-by-step explanation:
A ship left at the port at 9:00 p.m. and arrived at the next port at 5:00 a.m.
the next day. The distance between the 2 ports was 200 km.
Find the average
speed of the ship.
show solution
Answer:
25km/h
Step-by-step explanation:
It would be helpful to understand the 24 hour clock in this case so you don't get confused by the AM and PM. For reference, 5 AM is technically 17AM, since 5 + 12 = 17.
The ship departed at 9pm, subtract that from 17 and you'll get 8 hours.
17 - 9 = 8
We know that there are 8 hours total, and since the ship traveled 200km, we set up a fraction, which is 8hr/200km. Since we want the average speed, we'll go by km/hr. To do this, we need to set the hrs to 1.
8/x = 1
x = 8
200/8 = 25
Your answer is 25km/hr
