All angles in a triangle add up to 180°Step-by-step explanation:
Step 1: Set up equation
(x + 1)° + (10x - 7)° + (8x - 4)° = 180°
Step 2: Solve for x
Combine like terms: 19x - 10 = 180Isolate x term: 19x = 190Isolate x: x = 10Related Questions
If a gun fires 88 rounds per minute, how many rounds would it fire in 45 minutes?
Answers
Answer:
3960
Step-by-step explanation:
1minute = 88rounds
45minutes = xrounds
1/45 = 88/x
45(88)= 3960
3960/1 = 3960
x = 3960
The gun fires 3960 rounds in 45 minutes.
What is the proportion?A mathematical assessment of two numbers is called a proportion. If two sets of provided numbers rise or fall in the same relation, then the ratios are said to be directly proportional to each other.
Let x rounds would it fire in 45 minutes
As per the situation, we can write the proportion would be as:
1 minute : 88 rounds = 45minutes : x rounds
⇒ 1/88 = 45/x
Apply the cross-multiplication, and we get
⇒ x = 45(88)
⇒ x = 3960
This means a gun fires 3960 rounds in 45 minutes.

How do you know whether two quantities x and y are proportional?
1. Every ratio yx for related pairs of x and y is equivalent.
2. Every sum x + y is the same for related pairs of x and y.
3. Every x term is a multiple of the previous term.
4. Every difference x – y is the same for related pairs of x and y please help me
Answers
Answer:
The correct answer is:
1. Every ratio yx for related pairs of x and y is equivalent.
Step-by-step explanation:
Proportion is defined as the relationship between two quantities. When one quantity changes the other is also changes.
For two quantities y and x when we say that both are proportional then t can be written as:
y∝x
Removing the proportionality symbol introduces a constant which is the ratio of y and x.
[tex]\frac{y}{x} = k[/tex]
This ratio of y and x, i.e. k is equivalent for all related pairs of x and y.
Hence,
The correct answer is:
1. Every ratio yx for related pairs of x and y is equivalent.

Find the equation of the line that has a slope of 2
and passes through the point (5, -8). Write the
equation in point-slope form.
Answers
Answer:
The equation in the point-slope form will be:
[tex]y-(-8) = 2 (x-5)[/tex]
Step-by-step explanation:
The point-slope form of an equation is written as:
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope, and (x₁, y₁) is a point on the line.
Now, we will substitute the values of m and (x1, y1) in the given equation. Here,
m=2
and
(x1, y1) = (5, -8)
x1 = 5
y1 = -8
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-(-8) = 2 (x-5)[/tex]
Therefore, the equation in the point-slope form will be:
[tex]y-(-8) = 2 (x-5)[/tex]
The dimensions of a rectangular prism are 24 ft x 20 ft x 15 ft. What is the surface area
Answers
Answer:
2280 ft^2
Step-by-step explanation:
A rectangular prism has 6 faces. Each pair of opposite faces is congruent.
surface area = 2LW + 2LH + 2WH
surface area = 2(24 ft)(20 ft) + 2(24 ft)(15 ft) + 2(20 ft)(15 ft)
surface area = 960 ft^2 + 720 ft^2 + 600 ft^2

Step-by-step explanation
The sum of geometric sequence 2,10,50... up to 8 terms is 195312. Therefore, option C is the correct answer.
The given geometric sequence is 2+10+50+250+.....
What is the sum of the geometric sequence formula?Sum of the geometric sequence is S = a + ar + ar² +....+ [tex]ar^{n-1}[/tex].
The first term of the series is a and the common ratio is r.
The sum of the geometric sequence formula is [tex]S_{n} =\frac{a(r^{n} -1)}{(r-1)}[/tex] .
Now, a=2
To find r,
r = 10/2
r = 5 and n = 8
S = 2 ([tex]5^{8}[/tex]- 1) / (5 - 1)
S = 2(390625 - 1) / 4
S = (390624) / 2
S = 195312
Therefore, the sum of geometric sequence 2,10,50... up to 8 terms is 195312.

D. The graph is translated 2 units up.
E. The graph is vertically shrunk.
F. The graph is reflected across the x-axis.
Answers
Answer:
The descriptions that apply are E and F.
Step-by-step explanation:
Let's graph both functions, attached the result:
A: No. The graph is not reflected across x-axis. For this to happen, there should be a negative sign: g(x) = -x, for example
B: No, the graph doesn't translate. The graph only translates if there is: g(x) = a(x-c)+b, where b defines the vertical translation, and c the horizontal one.
C: No. This would happen for g(x)=x/2, for example.
D: No. Check the explanation of B.
E: Yes. The graph rotates due to the factor of 10. This rotation only applies for straight lines.
F: Yes. It stretched.
