Answer:

768.51

Step-by-step explanation:

To find 35% change the percentage to a decimal (.35)

Then multiply the original amount by .35

2195.73 *.35

768.5055

Since this is money, we round to the nearest cent

Answer:

(- 3, 0 ) and (5, 0 )

Step-by-step explanation:

To find the x- intercepts let f(x) = 0 , that is

x² - 2x - 15 = 0

Consider the factors of the constant term (- 15) which sum to give the coefficient of the x- term (- 2)

The factors are - 5 and + 3 , since

- 5 × 3 = - 15 and - 5 + 3 = - 2 , then

(x - 5)(x + 3) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 5 = 0 ⇒ x = 5

x + 3 = 0 ⇒ x = - 3

The x- intercepts are (- 3, 0 ) and (5, 0 )

Answer: It is 12

Step-by-step explanation:

Answer:

it is five

Step-by-step explanation:

5v-2=8 then v=x2 because 5x2=10-2=8

so 7v-9=5

The correct answer is 5

Answer:

1/13 (1 in 13)

Step-by-step explanation:

so, there's 4 aces in a standard deck of 52 cards.

so far, we can see this as 4/52 (4 in 52)

these are both divisible by 2, lets go ahead and simplify that to 2/26

still divisible by 2. this then becomes 1 /13

so, she has a 1/13 (1 in 13) chance to get an ace.

Answer:

[tex]\frac{3+/-i\sqrt{55} }{2}[/tex]

Step-by-step explanation:

[tex]x^2-3x=16[/tex]

Subtract 16 from both sides;

[tex]x^2-3x-16=0[/tex]

[tex]\frac{-(-3)+/-\sqrt{(-3^2)-4(-16)} }{2}=\frac{3+/-\sqrt{9-64} }{2}=\frac{3+/-\sqrt{-55} }{2}=\frac{3+/-\sqrt{55i^2} }{2} =\frac{3+/-i\sqrt{55} }{2}[/tex]

Answer:

b-16/25

Step-by-step explanation:

cause 0.64 would be 64/100 but I can be simplified down to 32/50 but that also could be simplified down to 16/25 which would be your answer because it can not be simplified any more

Answer:

#9

given, angle BOD = 95 degree

and angle     COD = 35 degree

assume that, angle BOC = x degree

so, angle BOC + angle COD = angle BOD

or, x + 35 degree = 95 degree

so, x = 95 degree - 35 degree = 60 degree

so, angle BOC = 60 degree

#10

given, angle AOC = right angle = 90 degree

and angle    AOB = 30 degree

assume that, angle BOC = y degree

so, angle AOB + angle BOC = angle AOC

or, 30 degree + y = 90 degree

so, y = 90 degree - 30 degree = 60 degree

so, angle BOC = 60 degree

Step-by-step explanation:

Step-by-step explanation:

The first part of solving the area is multiplying the rectangle. So you do 15*18 which is 270. Then to solve a triangle you make it a square/rectangle. So it would be 8*15 which is 120. Because the length is the length of the rectangle and the width is shown on top. Then because it’s a rectangle not a triangle you divide by 2 because you were adding half to it when you were making it a rectangle. So it’s 120/2 which is 60. And 270+60 is 330. So the area is 330. To get the perimeter you add all the sides together. And because one of the sides is not added but half of the bottom line is the same length as the top so it would be 18+ the 8 on the top which is 26. So 15+18+17+26 is 76. So the perimeter is 76

So the answer is the bottom one. P=76 and A=330

Answer:

Slope intercept form (y = mx + b) = [tex]y = \frac{2}{3} x + \frac{7}{3}[/tex]

X intercept (slope): [tex](-\frac{7}{2} , 0)[/tex]

Y Intercept: [tex](0, \frac{7}{3} )[/tex]

Step-by-step explanation:

To find the x-intercept, substitute in  0  for  y and solve for  x.

To find the y-intercept, substitute in  0  for  x and solve for  y.

Hope this helps! :D

Step-by-step explanation:

solve for y

[tex]3y - 7 = 2x[/tex]

isolate the y variable to one side

let's first add 7 to both sides of the equation

[tex]3y - 7 + 7 = 2x + 7[/tex]

sevens on the left side of the equation cancel so we get

[tex]3y = 2x + 7[/tex]

Now let's divide everything in the equation by 3 to further isolate the y variable

[tex] \frac{3y}{3} = \frac{2x}{3} + \frac{7}{3} [/tex]

The threes on the left hand side of the equation cancel

[tex] y = \frac{2}{3}x + \frac{7}{3} [/tex]
