Answer:

Step-by-step explanation:

All triangles have 180 as the sum of the 3 interior angles.

x + 74 + 55 + 54 = 180 Combine

x + 183 = 180 Subtract 183 from both sides.

x = 180 - 183 Combine

x = - 3

You probably have been told that there is no such thing as a minus angle, and that's true. The angle isn't minus. Just x is. The size of the angle is

Angle size = 74 - 3 = 71

Now try adding them together

55 + 54 + 71 = 180 which is what it should come to

Vadim26 [7]

Hence the answer is 480ml

Step-by-step explanation:

Given Elena wonders how much water it will take to fill her cup. She drops her pencil in the cup and notice it just fit diagonally. The pencil is 17cm long (hypotenes) and the cup is 15cm tall.

To find how much water it can hold

SOLUTION

$\sqrt{x {} ^{ 2} + x {}^{2} + 15 {}^{2} = 17 }$

$2x {}^{2} = 64$

$x {}^{2} = 32$

$x = 5.66$

therefore volume of the cup

$5.66 \times 5.66 \times 15cm|$

480cm³= 480ml

Select the correct answer1 - quadratic, linear, exponential2 - 1.5, 18, 16, 123 - 16, 12, 20, 184 - 18, 6, 20, 12

1 - The equation is:

$p(x)=-0.5x^2+6x$

Since it has no variable on exponents and it has a term with x to the second power, this is a quadratic function.

2 - x represents the length of the tomato patch, so if we want the area of the bell pepper patch, we can input x = 8 into the function:

$\begin{gathered} p(8)=-0.5\cdot8^2+6\cdot8 \\ p(8)=-0.5\cdot64+48 \\ p(8)=-32+48 \\ p(8)=16 \end{gathered}$

Thus, the area is 16 square feet.

3 - Since the leading coefficient is negative, the vertex of the parabola gives the maximum value for the function.

The x value of the vertex is:

$\begin{gathered} ax^2+bx+c \\ x_v=-\frac{b}{2a} \end{gathered}$

So, in this case:

$x_v=-\frac{6}{2\cdot(-0.5)}=-\frac{6}{-1}=6$

And to find the value for the area, we need to input that into the function:

$\begin{gathered} p(6)=-0.5\cdot6^2+6\cdot6 \\ p(6)=-0.5\cdot36+36 \\ p(6)=-18+36 \\ p(6)=18 \end{gathered}$

Thus, the maximum area is 18 square feet.

4 - The value for the length of the tomato patch is just the corresponding x for this maximum, which we calculated as the vertex x:

$x_v=6$

Thus, the length of the tomato patch for this maximum value is 6 feet.

What is the property of it

Olenka [21]

Answer:

Commutative Property of Addition

Step-by-step explanation:

The commutative property of addition says that changing the order of addends does not change the sum. This is what the problem is doing.
