multiply
(-8) x 11

Answer:

121°

Step-by-step explanation:

Sum of angles in a pentagon = ( n-2) 180

(5-2)180

=3x180

=540°

X+87+92+105+135=540

X+419=540

X=540-419

X=121°

Step-by-step explanation:

Since all 3 sides of the triangle is equal, it is not only an isosceles, but an equilateral triangle.

x = 8sin60° = 6.928 or sqrt48.

That is a question about triangles.

In my answer I will show 2 ways to solve that question, ok? Let's go.

The line segment x divide the biggest triangle in 2 equals right triangles.

Let's choose one of them and note that is a triangule with hypotenuse equals to 8 and one cathetus equals to half of 8.

The Pythagoras's theorem says that:

[tex]\boxed{a^2 = b^2 + c^2}[/tex]

a is the hypotenuse and b and c are cathetus.

So, in our case, we know the hypotenuse and one cathetus, let's substitute that in the expression:

[tex]a^2 = b^2 + c^2\\8^2 = 4^4 + c^2\\64 = 16 + c^2\\c^2 = 64 - 16\\c^2 = 64 -16\\c^2 = 48\\c = \sqrt{48}\\c= 4\sqrt{3}[/tex]

Therefore, the value of x is [tex]4\sqrt{3}[/tex].

That way to solve the question is a consequence of the previous way.

That triangle has all the sides equals, so it is a equilateral triangle.The line segment x is the height of that triangle. And we can find the equilateral triangle height using that expression:

[tex]\boxed{h = \frac{S\cdot \sqrt{3} }{2} }[/tex]

h is the height and S is the triangle's side.

So, we know that the side of our triangle is 8. Let's change S value in the expression:

[tex]h = \frac{S\cdot \sqrt{3} }{2} \\h = \frac{8\cdot \sqrt{3} }{3} \\h = 4\sqrt{3}[/tex]

Thus, the value of x is [tex]4\sqrt{3}[/tex].

Note that in the 2 ways we find the same result, so that answer is correct.

I hope I've helped. :D

Answer:

7.4 L per minute

Step-by-step explanation:

Volume of air = 37 L

Time = 5 minutes

What is the te of change of volume of air per minute?

Rate of change of volume of air per minute = Volume of air / Time

= 37 L / 5 minutes

= 7.4 L/minutes

That is, the rate of change of volume of air = 7.4 L per minute

Answer:

Y = 3/4x + -5

___________

y = 3/4x – 5

Step-by-step explanation:

y = mx + b

m = slope = change in y/change in x = rise / run

b = y intercept = point where x = 0

Answer:

The first choice

Step-by-step explanation:

y = mx+b

y = -3x+b

4 = -3*-1 + b

4 = 3 + b

b = 1.

Answer:

4

Step-by-step explanation:

Since the line of the function is passing through the point (3, 4).

Here x = 3 and y = 4

So the value of the function at x=3 is 4.

Answer: the first graph

Step-by-step explanation:

The intersection of the graph of the function with the y-axis gives the y-intercept of that function. The correct option is A.

The intersection of the graph of the function with the y-axis gives the y-intercept of that function. The y-intercept is the value of y on the y-axis at which the considered function intersects it.

Assume that we've got: y = f(x)

At the y-axis, we've got x = 0, so putting it will give us the y-intercept.

Thus, y-intercept of y = f(x) is y = f(0)

Given f(x)=2, therefore, the graph will have a y-intercept as 0.

But when the value of f(x) = 2(x) + 2, then the graph of the function will have the y-intercept at 2.

Hence, the correct option is A.

  Deb raised $34 less than Bashir, so (x+29)-34 = (x -5).

Answer:

C and D, x = 5

Step-by-step explanation:

To solve this problem, you add 9.2 to both sides then divide both sides by 5.5. The Addition Property of Equality states that if two expressions are equal to each other, and you add the same value to both sides of the equation, the equation will remain equal. This is the first step to solve the problem. The Division Property of Equality states that when we divide both sides of an equation by the same non-zero number, the two sides remain equal. That is the second step to solve the problem. To solve the problem, add 9.2 to both sides, that gets us 5.5x = 27.5. Now, we divide both sides by 5.5. That gets us x = 5.

18 flower boxes

Step-by-step explanation:

Given that:

Capacity of each flower box = 4

Number of flowers to plant :

Red = 38

White = 33

Total = (38 + 33) = 71 flowers

Fewest number of flower boxes needed to plant all flowers :

Total flowers to plant / capacity of each plant

71 / 4

= 17.75

= 18 boxes

Answer:

1.1n

0.6p

0.3b

Step-by-step explanation:

Simplifying Like terms

Like or similar terms are those who have the same letters raised to the same power. For example, 5ab, -6ba, 0.6ab are like terms.

Terms like 5xy, -6xz, [tex]9xy^2[/tex] are not similar because they have different letters of powers.

The terms 1.6n-0.5n are similar and they can be simplified by operating their coefficients: 1.6-0.5=1.1. Thus

1.6n - 0.5n = 1.1n

Similarly, we can simplify 0.9p-0.3p. Operating 0.9-0.3=0.6 gives the result:

0.9p - 0.3p = 0.6p

Finally:

b - 0.7b = (1 - 0.7)b = 0.3b

Results:

1.1n

0.6p

0.3b
