Answers

Answer 1
Answer: 55% of 40 is 22

Change the percentage into a decimal by dividing it over 100:

55/100 = 0.55

Divide:

22/0.55 = 40
Answer 2

Answers

The other form of circle equation is (x-a)2 + (y-b)2 = r2. a and b is the coordinate of the center and r is radius. So the equation is x2+(y-4)2=9. Change it to the general form is x2+y2-8y+7=0. So A=1, B=1, C=0, D=-8 and E=7.

PLATO SAMPLE ANSWER:

If the center of the circle is to the right of the y-axis, C is negative and its absolute value increases as the center moves to the right. If the center is to the left of the y-axis, C is positive and its value decreases as the center moves to the right. D does not change when the center moves horizontally.

If the center of the circle is above the x-axis, D is negative and its absolute value increases as the center moves up. If the center is below the y-axis, D is positive and its value decreases as the center moves up. C does not change when the center moves vertically.

The values of C and D are not affected when the radius changes, as long as the center stays the same.

Yoko paid $10.70 for stamps. She bought three times as many 25 cent stamps as 14 cent stamps, twice as many 2 cent stamps
as 25 cent stamps and the same number of one-cent stamps as
2 cent stamps. How many stamps of each type did Yoko buy?

Answers

Answer:

  • 30 of 25 cent, 10 of 14 cent, 60 of 2 cent

Step-by-step explanation:

  • Note: it must be typo 10.70, changed to 10.10

Number of 25 cent stamps = x

Number of 14 cent stamps = y

Number of 2 sent stamps = z

  • Total = $10.10 = 1010 ¢
  • x = 3y
  • z = 2x ⇒ z = 6y

Solving equation

  • 25x + 14y + 2z = 1010
  • 25(3y) + 14y + 12y = 1010
  • 75y + 26y = 1010
  • 101y = 1010
  • y = 1010/101
  • y = 10

The finding x and z

  • x = 3*10 = 30
  • z = 6*10 = 60

In a right triangle, the measures of the two smaller angles are (3X+6) and (2X-1) . Find the measure of the smallest angle in the triangle.

Answers

In a right triangle the biggest angle is 90°.

Then the two smaller angles sum up 180° - 90° = 90 °.

Now you can use this equation: 3x + 6 + 2x - 1 = 90 and solve for x:

5 x + 5 = 90
5x = 85
x = 85/5
x = 17

Then, the smallest angle is 2(17) - 1 = 33°

Then, the smallest angle is 2(17) - 1 = 33°

If EG=10x+20, FG=43. EG=183, find the value of x.

Answers

Answer:

Option (3)

Step-by-step explanation:

Given: EF = 10x + 20

           FG = 43

           EG = 183

From the figure attached,

Length of segment EF + length of segment FG = length of segment EG

By substituting the values of each segment in the equation,

(10x + 20) + 43 = 183

10x + 20 = 183 - 43

10x = 140 - 20

x = (120)/(10)

x = 12

Therefore, x = 12 will be the answer.

Option (3) will be the correct option.
