Answer:
b = 15.59
Step-by-step explanation:
a^2 + b^2 = c^2
9^2 + b^2 = 18^2
81 + b^2 = 324
-81 -81
b^2 = 243
b = 15.59
Pythagorean Theorem -
[tex]a^{2} + b^{2} = c^{2} [/tex]
1 - Input the values!
[tex] 9^{2} + x^{2} = 18^{2} [/tex]
2. Find the exponents!
[tex]81 + x^{2} = 324[/tex]
3. Multi step Equations!
[tex]81 - 81 = 0 \\ 324 - 81 = 243[/tex]
4. Use square roots to find x!
[tex]x = \sqrt{243}[/tex]
Answer: X=The Square Root Of 243

What is mArc SU?
49°
77°
98°
161°
Answer:
77°
Step-by-step explanation:
By the property of intersecting tangent and secant outside of a circle:
[tex]21 \degree = \frac{1}{2} ( 119 \degree - \widehat{SU} ) \\ \\ 42 \degree = 119 \degree - \widehat{SU} \\ \\ \widehat{SU} =119 \degree - 42 \degree \\ \\ \widehat{SU} =77\degree \\ \\ [/tex]
The mArc SU is option (B) 77 degrees
What is Tangent?A straight line or plane that touches a curve or curved surface at a point, but if extended does not cross it at that point.
What is secant ?A secant is a line that intersects a circle in exactly two points.
Here,
By the property of intersecting tangent and secant outside of a circle:
[tex]T=\frac{1}{2}(RU-SU)[/tex]
Here
T= 21 degrees
RU is the mArc RU = 119 degrees
Then,
[tex]21 =\frac{1}{2}(119-SU)\\ 42=119-SU\\SU=119-42[/tex]
SU = 77 degrees
Hence, the mArc SU is option (B) 77 degrees

Answer:
$109.97
Step-by-step explanation:
Each straight piece of wire is the diagonal of a square that is 3" on a side. The Pythagorean theorem tells you the length of that diagonal is ...
d = √(3^2 +3^2) = √18 = 3√2 . . . inches
There are 4 such diagonals on each trivet, so the total length of wire for 12 trivets is ...
(12)(4)(3√2) = 144√2 . . . inches
At a cost of $0.54 per inch, the total cost for 12 trivets will be ...
($0.54)(144√2) = $109.97
The cost of the copper wire for making 12 trivets is $109.97.

Step-by-step explanation:
adjacent angles are supp
Answer:
103° | See Attached Image
Step-by-step explanation:
The angle opposite of 77° is vertical (it makes an X, therefore the angles are equal.)
The corresponding angle to the vertical of 77° is also equal to 77°.
X is supplementary to the previously mentioned angle, so it adds up to 180°.
180 - 77 = 103°

f(n)=45⋅(4/5)^n−1
complete the recursive formula of f(n)
F(1) = 45
f(n) = f(n-1) * 4/5
Step-by-step explanation:
f(n) = 45 x (4/5)ⁿ⁻¹
f(1) = 45 x (4/5)¹⁻¹ = 45 x (4/5)⁰ = 45 x 1 = 45
f (n-1) = 45 x (4/5)ⁿ⁻¹⁻¹ = 45 x (4/5)ⁿ⁻²
f(n) = f(n-1) * (4/5)¹ = 45 x (4/5) ⁿ⁻²⁺¹ = 45 x (4/5)ⁿ⁻¹

Answer:
C
Step-by-step explanation:
Okay so on Saturday there is a 30% sale plus she comes early so +10% and that makes 40% off.
10% of 400=40
multiply by 4 to get 40%, 40*4=40%
40%=160
400-160=240
Hope this helps
400 x 0.30 = 120
400 - 120 = 280
280 x 0.10 = 28
280 - 28 = 252
So 252 is you answer.

Answer:
Step-by-step explanation:
3c + 2e = 6.10
e = c + 0.30
3c + 2(c + 0.30) = 6.10
5c + 0.60 = 6.10
5c = 5.50
c = 1.10 Є
e = c + 0.30 = 1.40 Є

Find the volume of this cylinder
Answer:
volume of cylinder= pie × radius square× height
= 22/7×4×20
=1760/7
=251.42cm
Answer:
using 3 for pi it's V = 960cm^3
Step-by-step explanation:
R is the radius, which as stated, is half the diameter.
r = 8cm / 2 = 4cm
H is the height, which is shown to be 20cm
h = 20cm
V = pi*r^2*h
V = pi*(4cm)^2*20cm
substituting 3 for pi as requested.
V = 3*(4cm)^2*20cm - 3 * (16cm^2) * 20cm = 48cm^2 * 20cm = 960cm^3
