Answer:

a. 125 degrees

b. 62 degrees

c. 58 degrees

d. 130 degrees

Step-by-step explanation:

I assume these are the inner angles of the polygons.

remember, for a polygon with n sides we can fully split it into n-2 triangles without overlap.

each of these triangles has an angle sum of 180 degrees.

to get the total inner angle sum of the polygon, we need to multiply 180 by (n-2) (= the number of triangles).

out of that total we can then calculate the size of the missing angle.

a. 6 sides, therefore 4 triangles

4×180 = 720 degrees

the missing angle is

angle = 720 - 88 - 152 - 125 - 105 - 125 = 125

b. 5 sides, 3 triangles

3×180 = 540 degrees

angle = 540 - 109 - 111 - 140 - 118 = 62

c. 4 sides, 2 triangles

2×180 = 360

angle = 360 - 60 - 142 - 100 = 58

d. 7 sides, 5 triangles

5×180 = 900

angle = 900 - 90 - 120 - 140 - 150 - 120 - 150 = 130

Answer:

f(4) = 0

Step-by-step explanation:

f(4) means what is the value of y when x = 4

Now x = 4 is on the x- axis, where y = 0, thus

f(4) = 0

The graph shows the type and number of coins that three students plan to donate during a coin drivefundraiser.Coin Drive Donatio

yarga [219]

Answer:

39 dimes

Explanation:

From the graph:

• Total number of nickels = 9+4+7=20

• Total number of dimes = 7+10+9 = 26

The ratio of total nickels to total dimes = 20:26

If the total number of nickels the students donate is increased to 30, we have:

$\frac{\text{Total Nickels}}{\text{Total Dime}}\colon\frac{20}{26}=\frac{30}{x}$

We then solve for x:

$\begin{gathered} 20x=30\times26 \\ x=\frac{30\times26}{20} \\ x=39 \end{gathered}$

The number of dimes they should donate to keep the ratio of total nickels to total dimes the same is 39.

Please help. I need this answer, thanks if you answered. Also please be correct

The correct answer is 5/7 and 5/4.

We have given that the expression

$a. \frac{2}{7}+\frac{3}{7}$

$b. 2\times \frac{1}{4} +\frac{3}{4}$

<h3>What is the dividando and componendo?</h3>

Components and dividend is a theorem on proportions that allows for a quick way to perform calculations and reduce the number of expansions needed. It is particularly useful when dealing with equations involving fractions or rational functions in mathematical Olympiads, especially when you see fractions.

We have to determine the value of the given expression,

$=\frac{2}{7}+\frac{3}{7} \\=\frac{5}{7}$

Similarly, for the second equation, we get,

$b. 2\times \frac{1}{4} +\frac{3}{4}\\=\frac{2}{4} +\frac{3}{4}\\=\frac{5}{4}$

Therefore the correct answer is 5/7 and 5/4.
