Answer:

80

Step-by-step explanation:

since all 3 angles of a triangle = 180

and two sides are parallel/same length to each other

180-50-50=80

so my guess is 80 degrees

Answer:

  $18.06

Step-by-step explanation:

The price the pawn shop charged for the DVD player was 40% more than what it paid, so was ...

  $12.00 + $12.00 × 0.40 = $12.00×(1 +0.40) = $16.80

__

The tax on the purchase is this price multiplied by the tax rate:

  tax = 0.075×$16.80 = $1.26

__

Then the total including tax is ...

  $16.80 +1.26 = $18.06 . . . . . total cost of the DVD player

Answer:

f(x)

Step-by-step explanation:

Because f(x) = 4x + 5

Answer:

f(x)

Step-by-step explanation:

g(x) intercept Is shown to be 2

f(x) if u sub 0 into x to find the y intercept gives you 5

h(x) I you sub 0 into the equation in place of x to find the y intercept it gives you -1.84

and if you look at all ghe y intersect values f(x) is the greatest

Answer:

36 square feet

Step-by-step explanation:

Check the attachment for the missing sides.

1) We calculate the missing sides by subtracting one of the similar sides with the longest one possible. In this case, 6 - 2 = 4 and 8 - 3 = 5.

2) Strikethrough the compound shape, creating two shapes; then, label them. Check the diagram attached.

3) Now, let's find the area of each of the squares; and then, add them.

Shape A:

= 4 × 5

= 20

Shape B:

= 2 × 8

= 16

Total:

= 20 + 16

= 36 feet²

Answer:

18.17 × pi in²

Step-by-step explanation:

there are many seemingly different formulas out there for this, but they are actually all the same and differ only by what values of the cone we know at the beginning (and the custodian values are converted into the values we need for the calculation).

do we know the base area and the height of the cone, or the radius and the height, or the base area and the slant height (the length of the "mantle" straight from the bottom to the top), ... ?

well, here we know the diameter (this means it is 2 times the radius) and the slant height.

this is one of the easiest exercises.

the formula for this case is

LA = pi × radius × slant height = pi × (4.6 / 2) × 7.9 =

= pi × 2.3 × 7.9 = 18.17 × pi in²

Answer:

[tex]5/4\ or\ 1 \frac{1}{4}[/tex]

Step-by-step explanation:

Step 1:  Determine a common denominator

Looking at the bottom of the fractions, also known as the denominator, we see that we are given 6, 3, and 12 which all can be multiplied to have the denominator as 12.

Step 2:  Convert the fractions to have a common denominator

[tex]5/6 * (2/2) = 10/12[/tex]

[tex]1/3 * (4/4) = 4/12[/tex]

[tex]1/12 * (1/1) = 1/12[/tex]

Step 3:  Add up the fractions

[tex]10/12 + 4/12 + 1/12[/tex]

[tex]15/12[/tex]

[tex]5/4[/tex]

Step 4:  Convert to mixed fraction

[tex]5/4[/tex]

[tex]4/4 + 1/4[/tex]

[tex]1 + 1/4[/tex]

[tex]1 \frac{1}{4}[/tex]

Anwer:  [tex]5/4\ or\ 1 \frac{1}{4}[/tex]

Answer:

Explanation:

[tex]\Longrightarrow \ \sf Give n \ A = \sf \bold{\begin{pmatrix}2&-9&8\\ 4&2&-1\\ -5&-3&7\\ 4&8&-4\end{pmatrix}}[/tex]

[tex]\Longrightarrow \ \sf Given \ B = \bold{\begin{pmatrix}-5&3&2\\ 1&4&-8\\ 7&-2&5\\ -3&5&-2\end{pmatrix}}[/tex]

Solve:

[tex]\sf A - B = \begin{pmatrix}2&-9&8\\ \:4&2&-1\\ \:-5&-3&7\\ \:4&8&-4\end{pmatrix}- \begin{pmatrix}-5&3&2\\ 1&4&-8\\ 7&-2&5\\ -3&5&-2\end{pmatrix}[/tex]

subtract the elements in matching positions

[tex]\sf A - B = \begin{pmatrix}2-\left(-5\right)&\left(-9\right)-3&8-2\\ 4-1&2-4&\left(-1\right)-\left(-8\right)\\ \left(-5\right)-7&\left(-3\right)-\left(-2\right)&7-5\\ 4-\left(-3\right)&8-5&\left(-4\right)-\left(-2\right)\end{pmatrix}[/tex]

Final Outcome

[tex]\sf \bold{\begin{pmatrix}7&-12&6\\ 3&-2&7\\ -12&-1&2\\ 7&3&-2\end{pmatrix}}[/tex]

Answer:

Step-by-step explanation:

The distribution can be described by its shape. If the line plot is bell-shaped, the distribution is: Normal

The distribution can be described by its center. If the distribution is bell-shaped, the mean or median is an accurate measure of center.

The distribution can be described by its spread. If the data set has an outlier, the IQR is an accurate measure of spread.

Answer:

I think its 6

Step-by-step explanation:

Answer:

Step-by-step explanation:

Outline

You could have 2 values. The way to get them is to take the square root of 25, c is double the value you get for the first step.  Why 25? Well you only have 1 other choice and that is the 1 that is in front of the x^2. That's not very helpful.

Formula

c = ± 2*sqrt(25)

Solution

c = ± 2 * sqrt(25)

c = ± 2 * 5

c = ± 10

Comment

Where does the ± come from?

You need to get + 25

If you have (x - 5)(x - 5) the last term will be -5 * - 5 = 25

Similarly you get the same result with (x + 5)(x + 5)

When we say an angle is on a circle, we mean the vertex is on the edge of the circle. One type of angle on a circle is the inscribed angle (see Inscribed Angles in Circles). Another type of angle on a circle is one formed by a tangent and a chord.
