Answer:

X=64°

Step-by-step explanation:

Solution,

x+54°=118° because the sum of two interior angles is equal to the opposite non adjacent exterior angle.

x+54°-54°=118°-54°

x=64°

Answer:

64 degrees

The Process:

54 is already a number that's not going to change, so that's fine. 118 is an outside angle, and a flat line is 180 degrees, so to find the inside angle, you have to do 180 - 118. Once again, there are 180 degrees in a triangle to you need to add 180 - ((180 - 118) +54) and you have the value of x.

Answer:

x = 70

Step-by-step explanation:

To find the value of x we need to

we know that the figure is an isosceles triangle so the base angles will be equal

we also know that angle sum of triangle is 180

so

40 + x + x = 180

40 + 2x = 180

2x = 180 - 40

2x = 140

x = 140/2

x = 70

Answer:

part 7 = 15cm

Step-by-step explanation:

[tex]x {}^{2} = (12) {}^{2} + (9) {}^{2} \\ x {}^{2} = 144 + 81 \\ x {}^{2} = 225 \\ x = \sqrt{225} = 15[/tex]

Answer:

(0,-5)

Step-by-step explanation:

To find midpoint the formula is

([tex]\frac{x1+x2}{2}[/tex] , [tex]\frac{y1+y2}{2}[/tex])

So plug in the numbers

([tex]\frac{2+(-2)}{2}[/tex], [tex]\frac{-1+(-9)}{2}[/tex]) = ( [tex]\frac{0}{2}[/tex] , [tex]\frac{-10}{2}[/tex])

Simplify it and it equals (0,-5)

Answer:

Zeke will receive $2.75.

Step-by-step explanation:

Helmet cost: (3/5) x 28.75 = $17.25

Gives = $20

20 - 17.25 = 2.75

Original question:

Zeke goes to a skate shop with his friend Tristan. Tristan buys a helmet that costs $28.75. Zeke finds a helmet that is (3/5) of the cost of Tristan's helmet. If Zeke gives the cashier a $20 bill, how much change will he receive?

Answer:

f(m+n+p) = 9^(m+n+p)

while f(m) × f(n) × f(p) = 9^m+9^n+9^p = 9^(m+n+p)

so the second property explains why it's a + instead of ×

Answer:

b = -30

Step-by-step explanation:

Answer:

Step-by-step explanation:

[tex](\sqrt{17}+3\sqrt{48})-(\sqrt{17}-3\sqrt{48}) =\sqrt{17}+3\sqrt{48}-\sqrt{17}+3\sqrt{48}\\[/tex]

                                                 [tex]= \sqrt{17}-\sqrt{17}+3\sqrt{48}+3\sqrt{48}\\\\= 0 + (3+3)\sqrt{48}\\\\=6\sqrt{48}\\[/tex]

Now factorize 48

[tex]= 6\sqrt{2*2*2*2*3}\\\\=6*2*2\sqrt{3}\\\\=24\sqrt{3}[/tex]

K is the midpoint of AB, which is the correct answer that would be option (A).

A midpoint is defined as in the middle of the line connecting two points a position known as a midpoint. A location in the middle of a line connecting the two points that are equally far from both points is the midpoint.

A line segment is defined as a measured path between two places. Line segments can make up any polygon's sides because they have a set length.

The figure given shows a line segment AT, where the length of line segment AT refers to the distance between its endpoints, A and T.

Here AB = 10, KB = 5, and BT = 4.

Since AB = AK + KB,

We have that 10 = AK+5,

And AK= 10 - 5 = 5.

This means that AK = KB = 5 and K is the midpoint of AB

Therefore, K is the midpoint of AB, which is the correct answer that would be an option (A).

Answer:

a

Step-by-step explanation:

Answer:

223.05/x(11.95+7.95) 11.21.

Step-by-step explanation:

If each hat costs 11.95 plus a shipping fee of 7.95, you must add those numbers together. This makes the variable that will help indicate the number of hats ordered. Then you divide 223.05 by 19.9 (the total cost per hat) and you'll get your answer of 11.21 rounded.

Answer: 139

Concept:

Here, we need to understand the idea of evaluation.  

When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.

Solve:

Given information

5x² - x + 9

x = -5

Substitute value into the expression

=5(-5)² - (-5) + 9

Simplify exponents

=5 (25) + 5 + 9

Simplify by multiplication

=125 + 5 +9

Simplify by addition

Answer:

pi*z^2*a or "pizza"

Step-by-step explanation:

The dimensions given describe a cylinder, for which the basic volume formula would be base x height.

The base would be a circle, with the radius z as given while the height is a.

The formula for the area of a circle is pi * r^2, and our radius is z, so the area of a circle with radius z is pi * z^2.

Now, all we need to do is multiply by the height, a. This gives us a volume of pi* z^2 *a

Side note:

z^2 can be written as zz, so the actual area of the pizza could be represented by "pizza".

A general line equation can be written as:

[tex]y = a*x + b[/tex]

Where a is the slope and b is the y-intercept.

Here we will find that for N(x₁, y₁), the line q is:

[tex]y = \frac{7}{6}*x + (y_1 - \frac{7}{6}*x_1)[/tex]

If we know that the line passes through the points (x₁, y₁) and (x₂, y₂), then we can write the slope as:

[tex]a = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

In this case, we know that the line passes through (-4, -4) and (2, 3), then the slope is:

[tex]a = \frac{3 - (-4)}{2 - (-4)} = \frac{7}{6}[/tex]

So the line is something like:

[tex]y = \frac{7}{6} *x + b[/tex]

To find the value of b, we can use one of the two points, for example (2, 3) means that when x = 2, y must be equal to 3, then we can replace these two in the line equation to get:

[tex]3 = \frac{7}{6}*2 + b\\\\3 = \frac{7}{3} + b\\\\3 - \frac{7}{3} = b = 2/3[/tex]

Then the line LM is;

[tex]y = \frac{7}{6}*x + \frac{2}{3}[/tex]

Now we know that line q is in the same coordinate plane, but does not intersect LM. This means that these lines are parallel, and remember that two parallel lines have the same slope, then the slope of line q is also 7/6.

Now we know that line q passes through point N, but we do not know the coordinates of point N, then let's use general coordinates as N(x₁, y₁)

Then line q will be:

[tex]y = \frac{7}{6}*x + c[/tex]

To find the value of c we use the point N.

[tex]y_1 = \frac{7}{6}*x_1 + c\\\\y_1 - \frac{7}{6}*x_1 = c[/tex]

Then the equation of line q is:

[tex]y = \frac{7}{6}*x + (y_1 - \frac{7}{6}*x_1)[/tex]
