Answer:
The value of [tex]x[/tex] is 15.222. We need to use the following equation: [tex]9\cdot x = 137^{\circ}[/tex]
Step-by-step explanation:
From Euclidean Geometry, we know that the sum of measures of internal angles in a triangle equals 180º. Then, we can find the value of [tex]x[/tex] by this formula:
[tex]43^{\circ}+3\cdot x + 6\cdot x = 180^{\circ}[/tex] (1)
[tex]9\cdot x = 137^{\circ}[/tex]
[tex]x = 15.222[/tex]
The value of [tex]x[/tex] is 15.222.

Answer:
If you aren't allowed to use calculators do (1280 - 128pi) but if you are do (877.876140341) Don't forget units in your work and answer.
Step-by-step explanation:
Volume of Rectangular prism = L*W*H = 8*10*16 = 1280in
Volume of Cylinder = pi*r^2*H = 8*pi*r^2
We know that the diameter is 8 (because that's the height of the rectangular prism as stated in the question) and diameter is 2*r thus the radius of the cylinder is 4.
therefore the volume of the cylinder is 8*pi*(4)^2 which is 128pi If you aren't allowed to use calculators do (1280 - 128pi) but if you are do (877.876140341)
Find a solution to this equation
y = x + 2
Type an (x,y) ordered pair that is a solution to this equation.
Answer:
(8,10)
Step-by-step explanation:
we could start off with that x as 0
0,?
since y-intercept is 2
(0,2)
then we could put x as 8
y=8+2
so y = 10 and x=8
(8,10)

According to the properties of inequality, when should the inequality symbol be reversed when solving a two-step inequality in the form below?
a x + b greater-than c
when a is positive
when a is negative
when b is positive
when b is negative
Answer:
B. when a is negativeStep-by-step explanation:
Inequality given:
ax + b > cWhen solving we do steps:
ax > c - bx > (c - b)/aAt the second step both sides divided by a.
When a is positive the inequality symbol remains as is, when a is negative we have to divide both sides by -1 as well. This will reverse the inequality symbol.
Correct answer choice is B.
Answer:
b

If z = 2, find the value of: a. 6z2–2z+5
b. 64–5z
Answer:
25 and 54
Step-by-step explanation:
(a)
6z² - 2z + 5 ← substitute z = 2
= 6(2)² - 2(2) + 5
= 6(4) - 4 + 5
= 24 - 4 + 5
= 20 + 5
= 25
(b)
64 - 5z ← substitute z = 2
= 64 - 5(2)
= 64 - 10
= 54

I got it wrong i need it help
Answer:
25
Step-by-step explanation:
Given,
Measurement of <1 = x + 10
Measurement of <2 = 4x + 5
Also, said in the question that both these angles are complementary.
Therefore, by the problem,
<1 + <2 = 90°
=> x + 10 + 4x + 5 = 90
=> x + 4x + 10 + 5 = 90
=> 5x + 15 = 90
=> 5x = 90 - 15 = 75
[tex] = > x = \frac{75}{5} [/tex]
=> x = 15
Now, we have got the value of x so,
Measurement of <1 is
<1 = x + 10 = 15 + 10 = 25 (Ans)

Simplify the product.
8p(-3p^2+6p-2)
Please show Step-by-Step
Answer:
-24p^3 + 48p^2 -16p
Step-by-step explanation:
Okay this isn't to hard for problems like this, you just have to multiply 8p to the numbers in the presentation so let's do it
8p*-3p^2= -24p^3
8*-3=-24
p*p^2=p^3
combine them both and get:
ans: -24p^3
8p*6p=48p^2
8*6=48
p*p=p^2
combine them both and get:
ans: 48p^2
8p*-2=-16p
8*2=-16
-16*p=-16p
ans:-16p
Then combine everything and get:-24p^3 + 48p^2 -16p

50w2−5w+25
Answer:
49w2+w+53
49 is a perfect square it'll be 7
Step-by-step explanation:
An expression has a leading coefficient that is a perfect square is 49w²+4+53.
What is a perfect square?A perfect square is a positive integer that is obtained by multiplying an integer by itself. In simple words, we can say that perfect squares are numbers that are the products of integers by themselves.
The term with the highest degree i.e., the term with the largest power of the variable is the leading term. The leading coefficient is the leading term's coefficient.
In the polynomial 49w²+4+53
The highest degree is with the term 49w² is 2, and its coefficient is 49.
49=7×7=7²

Step-by-step explanation:
a total of 420 tickets were sold for the school play. they were either adult tickets or student tickets. the number of students tickets sold was two times the numberof adult tickets sold. how many adult tickets were sold?
108 adult tickets sold.
Explanation:
To do this equation, we can set x equal to the number of adult tickets sold, and then set up the following equation:
x+3x=432
Since there are three times as many student tickets as adult tickets and the total is 432, you can just use all this information together to make an equation. From there, you can combine like terms to create this equation:
4x=432
After this, just divide both sides by 4 to reach the answer of:
x=108

(1,-2) as a function notation
Given:
The point is (1,-2).
To find:
The function notation of the given point.
Solution:
If a point is (x,y), then its function notation is f(x)=y.
The given point is (1,-2).
Here, x-coordinate is 1 and y-coordinate is -2. So, the function notation of the given point is
[tex]f(x-coordinate)=y-coordinate[/tex]
[tex]f(1)=-2[/tex]
Therefore, the function notation of the given point (1,-2) is f(1) = -2.
