Two angles are supplementary. If one angle measures twice the other, and the number of degrees in the smaller angle.
Answer:
60 Degrees
Step-by-step explanation:
Supplementary means it equals 180 together, so you divide it by 3 because the one is twice as big and you take the smaller answer
[tex]\frac{180}{3} =60[/tex]
Small and large angle are 60° and 120°.
Given that;
Angles are supplementary
Computation:
Assume;
Smaller angle = a
So,
Large angle = 2a
So,
In supplementary
a + b = 180
a + 2a = 180
3a = 180
a = 60
Smaller angle = 60°
Large angle = 2(60)
Large angle = 180°

Answer:
laptop: 14000
phone: 10200
Step-by-step explanation:
laptop: x + 3800
phone: x
x + 3800 + x = 24200
2x + 3800 = 24200
2x = 20400

Which expression is equivalent to 6423?
Owen made 60% of the shots he attempted during his hockey practice. He made 18 shots. How many shots did Owen attempt during his hockey practice?
Answer:
10.8 shots
Step-by-step explanation:
Owen made 60% of the shots he made, and he made 18 shots in total. Therefore, we would take 60% of 18. The answer we get is 10.8, but we can't have a part of a shot.
3=−2 |14s−5| +3 can i get a simple explination im kind of dumb lol
Answer:
s=5/14
Step-by-step explanation:
cancel equal terms on both sides of the equation
0=-2 x |14s-5|
swap the sides of the equation
-2 x |14s-5|=0
divide both sides of the equation by -2
|14s-5|=0
when the absolute value of 14s-5= 0, then 14s-5=0
move the constant to the right-hand side and change its sign
14s=5
now divide both sides of the equation by 14
s=5/14
When measuring the sides, triangles can be classified as acute, scalene and isoceles
Answer:
Yes, When measuring the sides, triangles can be classified as acute, scalene, and isosceles
Step-by-step explanation:
In any triangle, there are at least two acute angles
The types of triangles according to their angles are:
Acute-angled triangle ⇒ 3 angles are acuteRight-angled triangle ⇒ 2 acute angles and 1 right angleObtuse-angled triangle ⇒ 2 acute angles and 1 obtuse angleThe types of triangles according to their sides are:
Equilateral triangle ⇒ 3 equal sidesIsosceles triangle ⇒ 2 equal sidesScalene triangle ⇒ 3 different sideYou can classify the type of the triangle according to its angle using the measuring of its sides.
If a triangle has sides length a, b, c where c is the longest side
∵ a² + b² > c²
∴ The triangle is an acute-angled triangle
∵ a² + b² = c²
∴ The triangle is a right-angled triangle
∵ a² + b² < c²
∴ The triangle is an obtuse-angled triangle
You can classify the type of the triangle according to its sides using the measuring of its sides.
If a triangle has sides lengths a, b, c
∵ a, b, c have unequal lengths
∴ The triangle is scalene
∵ a and b or a and c or b and c have equal lengths
∴ The triangle is Isosceles
∵ a, b, c have equal lengths
∴ The triangle is equilateral
Yes, When measuring the sides, triangles can be classified as acute, scalene, and isosceles

Which of these relations is a function?
Why is this? This is the only relation that passes the vertical line test.
The other choices have situations where we can draw a single straight vertical line through more than one point on the blue curve. That means the graph fails the vertical line test and we do not have a function.
For a function to be possible, any x input must lead to exactly one y output.

X^2 - 6x - 7 = 0
Answer:
x = - 1, x = 7
Step-by-step explanation:
Given
x² - 6x - 7 = 0
Consider the factors of the constant term (- 7) which sum to give the coefficient of the x- term (- 6)
The factors are - 7 and + 1, since
- 7 × 1 = - 7 and - 7 + 1 = - 6, thus
(x - 7)(x + 1) = 0
Equate each factor to zero and solve for x
x - 7 = 0 ⇒ x = 7
x + 1 = 0 ⇒ x = - 1
5x-4 ≥12 or 12x+5 ≤-4

a) microwave ovens
b) brands
c) prices
d) colors
Answer:
a) microwave ovens
Step-by-step explanation:
Since we don't know what the dataset is, we cannot say with certainty what its elements are. The first sentence talks about microwave ovens, so it may be reasonable to assume that will be the members of the data set.

Mai uses Triangle A and says the slope of this line is 6/4.
Elena uses Triangle B and says no, the slope of this line is 1.5.
Do you agree with either of them? Explain.
The slope of the line is the ratio of the rise to the run, or rise divided by the run. Yes i can agree with both of their statements.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
As we know that the slope of a line will be always same on a given line. If slope triangle A has slope 6/4. Then triangle B will be also have the same slope.
As both triangles are connected to the same line. These two triangles A and B will have same slopes.
Mai uses Triangle A and says the slope of this line is 6/4.
If we convert fraction 6/4 to decimal we get 1.5 value.
So i agree with both of their statements.

A. (4, 8, 16) C. (8, 16, 4)
B. (4, 8, 12) D. (12, 6, 8)
Answer: C. (8, 16, 4)
Step-by-step explanation:
Given the following:
Let:
Trucks = T ; Cars = C ; SUVs = S
T =0.5(C + S) - 2 - - - (1)
C = 2T - - - (2)
T + C + S = 28 - - - (3)
T = 0.5(2T + S) - 2
T = T + 0.5S - 2
0 = 0.5S - 2
0.5S = 2
S = 2/0.5
S = 4
From T + C + S = 28
C = 2 T ; S = 4
T + 2T + 4 = 28
3T = 28 - 4
3T = 24
T = 24/3
T = 8
From T + C + S = 28
8 + C + 4 = 28
12 + C = 28
C = 28 - 12
C = 16
Hence, (T, C, S) = (8, 16, 4)

Answer:
7) (f+g)(x) = 4^x +5x -5
8) (f-g)(x) = 4^x +x +5
Step-by-step explanation:
7) add the two expressions.
(f+g)(x) = f(x) +g(x) = (4^x +3x) +(2x -5)
(f+g)(x) = 4^x +5x -5
__
8) subtract g(x) from f(x).
(f-g)(x) = f(x) -g(x) = (4^x +3x) -(2x -5) = 4^x +3x -2x +5
(f-g)(x) = 4^x +x +5

Kaitlyn is making big goods for charity bake sale he places a tray of scones a tray of muffins and a tray of cookies in the oven discounts bake for 15 minutes the muffins bake for 12 minutes and the cookies bake for 10 minutes when one trays done he removes it and replace it with another tray at the same I don't how many minutes after kaylan put the trays in the oven when he 1st remove the scones muffins and cookies at the same time
Answer:
So:
Counting from a given time t = 0min, we know that:
Each 15 mins she removes the scones
Each 12 mins she removes the muffins
Each 10 mins she removes the cookies.
So when will she remove both at the same time?
Well, this will happen in the smallest common multiple of 15, 12 and 10.
or at LCM(10, 12, 15).
How we find it?
well, in this case is easy.
All the multiples of 10 end with a zero.
So let's find the multiples of 12 and 15 that also end with a zero:
12*6 = 60
15*4 = 60
and
10*6 = 60
So the LCM(10,12,15) = 60.
Another way is by calculating:
10*12*15/(GCF(10,12)*GCM(12,15)*GCM(10,15)
Where GCF = greatest common factor.
Between 10 and 12 is 2.
Between 12 and 15 is 3
Between 10 and 15 is 5.
Then:
10*12*15/(2*3*5) = 60.
This means that 60 minutes after she starts, she will remove the scones, muffins and cookies at the same time.
