Answer:

7.27%

Step-by-step explanation:

Answer:

z*(z - 3) = 520

Step-by-step explanation:

Use the following representations:

Width:  W  

Length:  L = W + 3, or W = L - 3

Area = L*W = L*(L - 3) = 520

Equation b) is the correct one:  z*(z - 3) = 520

Answer:

Here is how you graph your equations correctly :D

Step-by-step explanation:

Graph y > x − 2.

Use the slope-intercept form to find the slope and y-intercept.

Slope: 1

y-intercept: (0, -2)

Graph a dashed line, then shade the area above the boundary line since y is greater than x − 2 .

y > x - 2

Graphy < −4x + 2.

Use the slope-intercept form to find the slope and y-intercept.

Slope: -4

y-intercept: (0, 2)

Graph a dashed line, then shade the area below the boundary line since y is less than − 4 x + 2 .

y < -4x + 2

Plot each graph on the same coordinate system.

y > x - 2

Y < -4x + 2

Answer:

its c 8%

Step-by-step explanation:

its c

Answer: 8%

Step-by-step explanation:

Answer:

(-4) - (+2) = -6

(+6) + (+9) = -3

(-36) divide (+3) = -12

(-12) x (-8) = 20

(-4) + (-7) = -11

(+7) - (4) = 11

(-5) - (+12) = 17

(+6) + (+9) = 15

(-10) + (+12) = -22

(+6) + (+6) = 12

(+10) divide (-10) = 1

(+4) + (-5) = -20

(-10) + (-10) = -20

(-4) x (+7) = 28

(+11) + (-2) = 9

(-2) - (-3) = 1

(-7) - (+1) = -8

(+1) + (+4) = 5

geez this took me a while lol

i hope that help!

an = 2n

1 = 2(1) = 2

2 = 2(2) = 4

3 = 2(3) = 6

4 = 2(4) = 8

so, the first four terms are 2 , 4 , 6 , 8.

Answer:

20 boys in class

Step-by-step explanation:

easy

x+(x+5)=35

30=2x

x=15

Answer:

let X be number of boys & y be number of girls in the class

x +y = 35 .....eq 1

x = y +5

y = x -5.......... eq 2

substitute eq 2 in eq 1

x + x -5 =35

2x = 40

x = 20

The value of  function f(-7) is 157.

Functions have the property that each input is related to exactly one output. The function defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

For the given situation,

The function is f(x) = 3 x^2 + 10

Then  f( - 7) becomes,

⇒ [tex]f(-7)=3(-7 )^{2} +10[/tex]

⇒ [tex]f(-7)=147+10[/tex]

⇒ [tex]f(-7)=157[/tex]

Hence we can conclude that the value of  function f(-7) is 157.

Answer:

151 ft

48 ft/s

Step-by-step explanation:

h(t)=-16t^2+v₀t+h₀

v₀ = 96  and

h₀ = 7

h(t)=-16t^2+96t+7

The maximum height is at the vertex

The x values of the vertex is at

x = -b/2a = -96/ (2*-16) = -96/-32 =3

Substitute this into the function to find the maximum height

h(3) = -16 ( 3)^2 +96*3+7

    -16*9 +288+7

     151

The maximum height is 151 ft

Average rate of change from 0 to 3

[tex]y = \frac{1}{9}x + 2 \\ [/tex]

Subtract the sides of the equation minus 2

[tex]y - 2 = \frac{1}{9}x \\ [/tex]

Multiply the sides of the equation by 9

[tex]9(y - 2) = x[/tex]

[tex]9y - 18 = x[/tex]

Step-by-step explanation:

396/12 = 33

Answer:

72

Step-by-step explanation:

9/11 = ?/88

multiply each side by 8 (because 88 divided by 11 is 8)

72/88 = ?/88

multiply each side by 88

72 = ?

10. x = 180-81= 99 = 180-(99+19)= 62°

11. x = 180-115= 65 = 180-(65+41)= 74°

12. x = 180-(36+42) = 102 = 180-102 = 78°

13. a = 180-(112+33) = 35°

14. b = 180-(71+35) = 74°

15. c = 180-(43+71) = 66°

Answer:

The number of quarters in total = 16 quarters

The number dimes = 32 dimes

Step-by-step explanation:

The given information are;

The total amount of money in held = $7.20

The denomination of the money held = Dimes and quarters

The number dimes = 2 × The number of quarters

Given that a dime = 10 cents = $0.1

A dollar = 25 cents = $0.25

Let the number of quarters in the sum of money = X

Therefore, we have;

X × $0.25 + 2 × X × $0.1 = $7.20

X × $0.25 + X × $0.2 = $7.20

X × $0.45 = $7.20

X = $7.20/$0.45 = 16

Therefore, the number of quarters = 16

The number of quarters in total = 16 quarters

The number dimes = 2 × The number of quarters = 2 × 16 = 32 dimes

The number dimes = 32 dimes.

Answer:

I think it is 350(1.2)^t because you take the starting amount (350) and then multiple it by the growth rate (which is 20%, but when added to 100 and the put into a decimal is 1.2) raised by the number of hours (t).
