Work Shown:
Let x be the measure of each of the two angles (which is valid because they both have the same measure). Since they are complementary, the angles add to 90
So,
x+x = 90
2x = 90
x = 90/2
x = 45
Each angle is 45 degrees
45+45 = 90

Answer:
1) 18 quarters and 30 nickels2) 8 quarters and 12 nickelsStep-by-step explanation:
1) Let quarters be x and nickels be y.
Equations based on given, 48 coins, total of $6 = 600c:
x + y = 4825x + 5y = 600Substitute y in the second equation, y = 48 - x
25x + 5(48 - x) = 60025x + 240 - 5x = 60020x = 360x = 18Then value of y is:
y = 48 - 18 = 302) Similarly to problem 1.
x + y = 2025x + 5y = 260Substitution: y= 20 - x
25x + 5(20 - x) = 26025x + 100 - 5x = 26020x = 160x = 8Then finding y:
y = 20 - 8 = 12ALREADY LATE PLS HELP!!!

The volume of a sphere with a radius of 3 cm is 14.3 cm³.
What is a sphere?In geometry, a sphere is a three-dimensional solid figure, which is round in shape.
The surface area is 4πr².
The volume is (4/3)πr³.
The diameter is 2×radius of the sphere.
We know a glope is in the form of a sphere.
We also know that the volume of a sphere is (4/3)πr³.
Therefore, The volume of a sphere with a diameter 3 cm Or a radius of
(3/2) cm has a volume,
= (4/3)π(3/2)³ cm³.
= 14.3 cm³.

What is the value of g(-9) for the function g(x) = x2 - x?
Answer:
72Step-by-step explanation:
Given the function;
g(x) = x^2 - x
We are to find g(-9)
g(-9) = (-9)² - 9
g(-9) = 81 - 9
g(-9) = 72
hence the value of g(-9) is 72

f(x)=-1/2(1-x)^2,
find f(-5).
Answer:
f(x)= -1/2(1-x)^2
replacing x with -5 since -5 was given as the function
f(-5)=-1/2(1-5)^2
according to bodmas we solve what is in the bracket first
f(-5)=-1/2(-4)^2
f(-5)=-1/2(16)

Let r = ⟨5, –1⟩, s = ⟨6, 0⟩, and t = ⟨–1, –3⟩. Aaron incorrectly determined 2r + 4s – 7t as ⟨41, –23⟩. Review his calculations.
2r + 4s – 7t
2⟨5, –1⟩ + 4⟨6, 0⟩ – 7⟨–1, –3⟩
⟨10, –2⟩ + ⟨24, 0⟩ + ⟨7, –21⟩
⟨41, –23⟩
What mistake did Aaron make?
He added ⟨10, –2⟩ + ⟨24, 0⟩ + ⟨7, –21⟩ incorrectly.
He should have subtracted ⟨7, –21⟩ rather than add.
He did not correctly distribute 4 to both components of s.
He did not correctly distribute the negative when subtracting 7t.

do –2(3x – 1) = –6x – 1 have one solution
Answer:
No solutions
Step-by-step explanation:
–2(3x – 1) = –6x – 1
First distribute the left side
-6x + 2 = -6x - 1
Add 1 to both sides
-6x + 3 = -6x
Add 6x to both sides
