Answer:

8

Step-by-step explanation:

I'm guessing the answer is 8 because when y is -8, x is 4. So, my thought in mind is when x is negative, y is positive. It also says, "If the value of "y" varies directly with "x". So, this means the answer is 8. You're very much welcome! Also, I'm sorry if this is incorrect. I tried my best with this question but I'm pretty sure the answer is 8! Have a great day sunshine!! :)

Explanation:

Let's find the expression for angle TUS in terms of x

Angle TUA has the expression 11x+2. It will add to angle TUS to get 180 degrees

(angle TUS) + (angle TUA) = 180

angle TUS = 180 - (angle TUA)

angle TUS = 180 - (11x + 2)

angle TUS = 180 - 11x - 2

angle TUS = -11x + 178

Now focus on the interior angles of triangle TUS. We have these three angles

For any triangle, the interior angles always add to 180, so,

T+U+S = 180

(5x+10) + (-11x+178) + (58) = 180

(5x-11x) + (10+178+58) = 180

-6x + 246 = 180

-6x = 180-246

-6x = -66

x = -66/(-6)

x = 11

Use this x value to find the angle measures we're after:

--------------------------

As an alternative route, you can apply the remote interior angle theorem. This says that adding two interior angles leads to the exterior angle that isn't adjacent to either one.

In this case, we would say

(angle STU) + (angle TSU) = angle TUA

that leads to the equation

(5x+10) + (58) = 11x+2

Solving this should lead to x = 11 to generate the angles mentioned earlier.

Answer:

D. c(p) = 0.59p

Step-by-step explanation:

The total cost, c(p), to purchase sugar is equal to the product of the pound cost equal to $0.59 and the number of pounds of sugar, p. Thus, the answer to this item is C(p)=0.59p

The total cost, c(p), to purchase sugar is equal to the product of the pound cost equal to $0.59 and the number of pounds of sugar, p. Thus, the answer to this item is,

                                c(p) = ($0.59)p

We multiply the number of pounds of sugar, p, time the cost per pound ,.59, to get the total cost

c(p) = .59*p

Answer:

2.4

Step-by-step explanation:

Smaller sheet length = 10u

Smaller sheet width = 10u

Smaller sheet area = 10u * 10u = 100u^2

Larger sheet length = 1.5 * 10u = 15u

Larger sheet width = 1.6 * 10u = 16u

Larger sheet area = 16u * 15u = 240u^2

240u^2 / 100u^2 = 2.4

The factor when the area of the larger sheet greater than the area of the smaller sheet should be considered as the 2.4.

Since

Smaller sheet length = 10u

Smaller sheet width = 10u

Now

Smaller sheet area = 10u (10u) = [tex]100u^2[/tex]

And,

Larger sheet length = 1.5 ( 10u) = 15u

And,

Larger sheet width = 1.6 (10u) = 16u

So,

Larger sheet area = 16u (15u) = [tex]240u^2[/tex]

Now

[tex]= 240u^2 \div 100u^2[/tex]

= 2.4

hence, The factor when the area of the larger sheet greater than the area of the smaller sheet should be considered as the 2.4.

Answer:

1 The angles in an equilateral triangle are always 60°. When a triangle has two congruent sides it is called an isosceles triangle. The angles opposite to the two sides of the same length are congruent. A triangle without any congruent sides or angles is called a scalene triangle.

Answer:

To find the slope, use the formula rise/run or change in y/change in x

In this case, the slope is 5

To find y-intercept, substitue  values for x and y

Step-by-step explanation:

-3 = 5(2) + b

-3 = 10 + b

-10    -10  

-13 = b

Therefore, b is -13

So here's how the equation looks in slope-intercept form

y = 5x + -13

Answer:

The measurement of the third angle would be 139 degrees.

Step-by-step explanation:

Using the triangle sum theorem, you already know that all interior angles of a triangle add up to 180 degrees. So since you already have two angle measurements, all you have to do is add them together and subtract them from 180 degrees. In this case it is 29+12, which equals 41. Now you subtract that from 180 and get 139.

Answer:

Step-by-step explanation:

Let the roof be square shaped

Area of the roof = L²

L is the side length of the roof

Given

L = 40ft

Area of the roof = 40²

Area of the roof = 1600ft²

If plants used for a green roof cost $0.75 per square foot, this means

1 ft² = $0.75

Let the cost needed to cover both sides of the roof be y, hence;

1600ft² = y

Divide both expressions

1/1600 = 0.75/y

y × 1 = 0.75×1600.

y = 0.75×1600

y = 1200

Hence it will cost $1200 to cover both sides of the roof
