1. 11x36=396

penjelasan: Cara cepetnya pertama taro 3 di awal 6 diakhir teruskan tengahnya kita gatau isinya berapa jadi caranya 3 plus 6 jadi 9 jadi hasilny 396.

2. 20x30 = 600

3. 35 + 15 = 50

4. 100x (25-12) = 1300

5. 60 + 20 + 30 = 110

6. 100 % + 200 % = 300 %

7. 25/4 x 100 = 625

8. cos 210 = 1/2 akar 2

9. 999 - 99 = 900

10. 24/33 x 11 = 8

Algebra 2 need help on a ( ABC )
Len [333]

Answer:

b)

x =  \frac{15}{4}

Step-by-step explanation:

b) set up equations so they are equal to each other,

2x - 2 =  - 3x + 12

5x = 14

x = \frac{14}{5}

this is when f(x)=g(x) so our approximation was close.

c)solving it graphically is nearly impossible because the solution can be any value around the intersection. only way to be sure is to solve it symbolically.

For the rotation - 660°, find the coterminal angle from 0° < 0 < 360°, thequadrant and the reference angle.
guajiro [1.7K]

Given the angle:

-660°

Let's find the coterminal angle from 0≤θ≤360.

To find the coterminal angle, in the interval given, let's keep adding 360 degrees to the angle until we get the angle in the interval,

We have:

Coterminal angle = -660 + 360 = -300 + 360 = 60°

Therefore, the coterminal angle is 60°.

Since 60 degrees is between 0 to 90 degrees, is is quadrant I.

60 degrees lie in Quadrant I.

Also since it is in quadrant I, the reference angle is still 60 degrees.

ANSWER:

The coterminal angle is 60°, which lies in quadrant I, with a reference angle of 60°

Cambridge slim ate 27 sausages in the first 11 minutes of a high stakes eating contest assuming that he conuitnes at the same pa
velikii [3]

Answer: 36 whole sausages by the end of the contest.

Step-by-step explanation:

We know that he ate 27 sausages in 11 minutes, then the rate at which he ates sausages is:

R = (27 sausages)/(11 minutes) = 2.45 sausage/min

So if he ate at this rate for 15 minutes, the total number of sausages eaten by the end is:

Total number = (2.45 sausage/min)*15min = 36.8 sausages

(where we are counting again the 27 sausages that he ate in the first 11 mins)

If we only count the number of whole sausages eaten, he ate 36 whole sausages.

Which function has zeros at x=-2 and x=5?
Licemer1 [7]

Answer:

x^{2} - 3x - 10

Step-by-step explanation:

To start, lets form our polynomial factors from our zeroes.

x = -2

x + 2 = 0

x = 5

x - 5 = 0

Now lets put these into factored form by moving them into parenthesis and multiplying them with each other!

(x+2)(x-5)

We can start moving them out! I am going to use FOIL, but you could also use distributive or any other method/property.

x · x = x²

x · -5 = -5x

x · 2 = 2x

2 · 5 = 10

Now lets put our terms into our polynomial function, based on the order of the powers.

x^{2} - 3x - 10

We are done! Hope this helps!

Members of the band are selling candy bars to raise money. The director uses this equation to calculate the amount of profit, p,
ivolga24 [154]

Answer:

<h3>C. 800</h3>

Step-by-step explanation:

Given the equation used to calculate the amount of profit, p, made from selling n candy bars expressed as  p = 1.50n – 500

To find the number of candies sold for $700, we are going to substitute p = $700 into the given expression and find n as shown;

700 =  1.50n - 500

Add 500 to both sides

700+500 = 1.50n-500+500

1200 = 1.50n

Divide both sides by 1.50

1200/1.50 = 1.50n/1.50

800 = n

Rearrange

n = 800

Hence 800 candy bars must be sold to make $700 profit
