What do the sides in a triangle add up to? I know that the inner angles of a triangle add up to 180°, but what do the sides of a triangle add up to?
Answer:
The most basic fact about triangles is that all the angles add up to a total of 180 degrees. The angle between the sides can be anything from greater than 0 to less than 180 degrees. The angles can't be 0 or 180 degrees, because the triangles would become straight lines.

-9y-2=x
4x-3y=31
Solve by substitoution
Answer:
x=7
y=-1
Step-by-step explanation:
x=-9y-2--------(1)
4x-3y=31
4x=31+3y
x=31/4+3/4y-------(2)
x=-9y-2=31/4+3/4y
-9y-3/4y=31/4+2
-39/4y=39/4
y=-1
substitute in 1
(-9*(-1))-2=x
x=7
Which of the following questions is a statistical question

I believe your answer is:
The first question.

Here’s why:
⸻⸻⸻⸻
Statistical questions have answers in which data varies. The first question, "How many sticks of gum can you chew at one time?" can be statistical because not all people can chew the same number at one time. Some can chew 2 sticks, others can chew 3 or 4.The other three questions can be answered with a fixed number.⸻⸻⸻⸻

Triangle not drawn to scale
O A. 3.5 yds
O B. 4.1 yds
C. 2.8 yds
D. 4.5 yds
Answer:
3.5 yards
Step-by-step explanation:
The value of c in the triangle ABC is 3.5 yds, Option A is correct.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
The given triangle is ABC.
We have to find the length c in the triangle.
Now let us use sine rule to find the value of c.
c / sin 28° = 4 / sin 32°
The value of sin 28° is 0.4695 and sin 32° is 0.5299
c / 0.4695 = 4 / 0.5299
Apply cross multiplication
c × 0.5299 = 4 × 0.4695
c × 0.5299 = 1.8636
Divide both sides by 0.5299
c = 1.8636/0.5299
c = 3.516
= 3.5 yds
Hence, the value of c in the triangle ABC is 3.5 yds, Option A is correct.

Find the number if 20% of 64 is 10% of it?
Answer:
128
Step-by-step explanation:
20% of 64
= 0.2 × 64 = 12.8
10% = 12.8 , then
100% = 12.8 × 10 = 128
Answer:
The number is 128
Step-by-step explanation:
Let the number be represented by X
Therefore
20/100*64=10/100*X
---10X=1280
Now dividing both sides of the equation by 10 it will be
=10X/10=1280/10 which is
---X=128
Therefore the number is 128

Find the value of x in the triangle shown below.
13
5
х
Answer:
x=12
Step-by-step explanation:
This is a right triangle, so the Pythagorean theorem can be used. The Pythagorean theorem states that [tex]C^2=a^2+b^2[/tex] where C is the hypotenuse and a and b are legs. In this question, we are given a and C. So, plugin 13 for C and 5 for a and solve for b. Once you rearrange the equation you get, [tex]b=\sqrt{13^2-5^2}[/tex]. Next, solve what is under the root to get, [tex]b=\sqrt{144}[/tex]. Finally, square root 144 for the final answer b=12.
Answer:
x = 12
Step-by-step explanation:
c² = a² + b²
13² = 5² + b²
169 = 25 + b²
b² = 169 - 25
b² = 144
b = 12

Help me with this question please‼️‼️
Explanation:
The gradient is the same as the slope
m = slope
m = rise/run
m = (change in y)/(change in x)
m = (y2-y1)/(x2-x1)
m = (6-1)/(6 - (-4))
m = (6-1)/(6+4)
m = 5/10
m = 1/2
In decimal form, this becomes 0.5
A slope of 1/2 means we move up 1 and to the right 2 units each time to generate points along the diagonal line.
A positive slope goes uphill as we move to the right (due to the positive rise value).
Answer:
One way to find the gradient is using the expression :
[tex]m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} = \frac{y_{B} - y_{A}}{x_{B} - x_{A}}[/tex]
So [tex]m = \frac{6 - 1}{6- (-4)} =\frac{5}{10} =\frac{1}{2}[/tex]

Answer:
a) q = 15 at minimum average cost; q = 10 at minimum marginal cost
b) marginal cost = average cost = 225 at q = 15
Explanation:
The average cost is the total cost divided by the number of units.
A = C/q = 300 -10q +1/3q^2
The marginal cost is the derivative of the total cost.
M = 300 -20q +q^2
__
a) The minimum average cost is where its derivative is zero.
A' = 0 = -10 +2/3q ⇒ q = 15
The minimum marginal cost is where its derivative is zero.
M' = -20 +2q ⇒ q = 10
__
b) The average cost for 15 units produced is ...
A(15) = 300 -10(15) +1/3(15^2) = 225
The marginal cost at that same production level is ...
M(15) = 300 -20(15) +15^2 = 225
The average cost and marginal cost are equal at the minimum average cost.
