Answer:

3. 60° is the correct answer.

Step-by-step explanation:

3. sum of all the sides of a quadrilateral is 360°

hence,

2h+2h+h+h=360°

6h=360°

h=360°/6

h=60°

4. Sum of interior angle of a polygon with n sides is 1080. N=8 (octagon)

Hope this helps you. Have a nice day.^_^

Which function has the same y-intercept as the function y equals 2/3 x - 3​
aleksley [76]

We have the function y = \frac{2}{3} x -3 and we want to find a function that has the same y-intercept than the previous function.

First, let's find the y-intercept by subtituting 0 for 'x'.

y = \frac{2}{3} (0) -3 = -3

Now that we found that y-intercept =-3, any lineal function of the type: y = ax - 3 will have the same y-intercept. Where 'a' can take all the real values.

Also, any quadratic function of the type: y=ax^{2} + bx - 3 will have the same y-intercept. Where 'a' and 'b' can take all the real values.

Question is shown below.
Andrei [34K]

ANSWER

D. 4 minutes 40 seconds

EXPLANATION

The given data set showing the number of seconds of each song the playlist is:

283,204,198,229,173,230,168,236,215,204

Let the length of the 11th song be x.

Because he wants the mean to be 3 minutes 40 seconds, which is equal to 220 seconds, we write and solve the following equation for x.

\frac{283 + 204 + 198 + 229 + 173 + 230 + 168 + 236 + 215 + 204 + x}{11}  = 220

\frac{2140 + x}{11}  = 220

2140 + x = 2420

x = 2420 - 2140

x = 280

We convert 280 seconds to minutes.

\frac{280}{60}  = 4 \frac{2}{3}  = 4mins : 40 sec

The correct choice is D

Mina has 4/5 of the flour she needs to make a loaf of bread. It takes the same amount of flour to make 1 loaf of bread as it tak
KATRIN_1 [288]

Answer:

<h2>Mina can make 9 rolls with 4/5 of flour.</h2>

Step-by-step explanation:

Givens

  • Mina has 4/5 of the flour she needs to make a loaf of bread.
  • 1 loaf of bread requires the same amount of flour than 12 rolls.

Basically, the problem states that with the complete flour, which is 5/5, Mina can make 12 rolls or 1 loaf of bread. Using the rule of three, if 5/5 is equivalent to 12 rolls, how many rolls would be 4/5 of the flour.

x=\frac{4}{5} \ flour \times \frac{12 rolls}{1 \ flour}= 9.6

Therefore, Mina can make 9 rolls with 4/5 of flour.

(Notice that the result is 9.6, however we can't use the approximation 10, because that would imply an incomplete roll.
