What is the percent of change from 100 to 23

Answer:

A. $47,403.20

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

For this, the question is about Simple Interest, so the formula is PRT

p- principal (the amount of money you started with)

r- (rate, also the percentage)

t- time (the amount of time it says, in years or so)

So, they had $45,580

Multiply that by 4%, and 4% is 0.04 so multiply 0.04 x 45,580 = 1,823.20. So, the answer is D

Hope this helps!!

Answer:

plug in -1 for x and 2 for y

solve equation

Step-by-step explanation:

y= 3x+5

2= 3(-1) + 5

2= -3 + 5

2= 2

Answer:

[tex]x=\frac{1+\sqrt{31}}{2},\:x=\frac{1-\sqrt{31}}{2}[/tex]

Step-by-step explanation:

[tex]-> 0=2x^2-2x-15[/tex]

-zeros means the solution aka x intercept, meaning y=0

[tex]x_{1,\:2}=\frac{-\left(-2\right)\pm \sqrt{\left(-2\right)^2-4\cdot \:2\left(-15\right)}}{2\cdot \:2}[/tex]

=> according to quadratic formula

[tex]x_{1,\:2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

where [tex]ax^2+bx+c=0[/tex]

=> [tex]x_{1,\:2}=\frac{-\left(-2\right)\pm \:2\sqrt{31}}{2\cdot \:2}[/tex]

simplify

[tex]x_1=\frac{-\left(-2\right)+2\sqrt{31}}{2\cdot \:2},\:x_2=\frac{-\left(-2\right)-2\sqrt{31}}{2\cdot \:2}[/tex]

[tex]x=\frac{1+\sqrt{31}}{2},\:x=\frac{1-\sqrt{31}}{2}[/tex]

Cannot simplify farther

Answer:

356.93sq. cm

Step-by-step explanation:

Area of the composite figure = Area of rectangle + Area of semicircle

Area of rectangle = length * wiidth

Area of rectangle =  14cm * 20cm

Area of rectangle = 280 sq. cm

Area of semicircle = πr²/2

Area of semicircle = 3.14(7²)/2

Area of semicircle  = 3.14 * 49/2

Area of semicircle  = 76.93 sq. cm

Hence the area of the figure = 280 + 76.93

Hence the area of the figure = 356.93sq. cm

Answer:

n = 95.75

m = 17.75

Step-by-step explanation:

n = one number

m = another number

System of Equations:

n = 7+5m

n - m = 78

Substitution Method:

7+5m - m = 78

4m + 7 = 78

4m = 71

m = 17.75

n - 17.75 = 78

n = 95.75

Answer: x = 3

Step-by-step explanation:

-10x - 2y = -30

3x + 2y =9

use elimination method...

-2y and 2y = 0

-10x = - 30

3x = 9

add together...

-7x = -21

solve...

x= 3

Three ways to write 5^11

In product:48828125

In powers:

[tex]5^{11}[/tex]

5 to the power of 11

Step-by-step explanation:

I learned this before in class like few years ago

Answer:

5^1 * 5^10

5^2 * 5^9

5^3 * 5^8

5^4 * 5^7

5^5 * 5^6

also

5^11 * a^0 (for any a except 0)

Answer:

1.3 + 1.3 = 2.6

2.6 x 2.2 = 5.72

5.72 divided by 2 = 2.86

2.86 x 2 = 5.72

Answer: 37, [tex]\frac{x+2}{7}[/tex]

Step-by-step explanation:

Given

[tex]f(x)=7x-2\\g(x)=x^2+1\\h(x)=3x[/tex]

now,

[tex]g(h(x))=(3x)^2+1\\g(h(x))=9x^2+1[/tex]

for x=2

[tex]g(h(2))=9\cdot (2)^2+1\\g(h(2))=36+1\\g(h(2))=37[/tex]

Inverse of [tex]f(x)[/tex] is given by

[tex]y=7x-2\\x=\dfrac{y+2}{7}\\\\f^{-1}(x)=\dfrac{x+2}{7}[/tex]

Answer:

Volume = 2,143.57 mm³

Step-by-step explanation:

Given:

radius (r) = 8 mm

π = 3.14

Required:

Volume of the sphere

Solution:

Volume of the sphere = ⁴/3πr³

Plug in the values

Volume = ⁴/3 × 3.14 × 8³

= ⁴/3 × 3.14 × 512

= 6,430.72/3

Volume = 2,143.57333

Volume = 2,143.57 mm³ (nearest hundredth)

Answer:

1/3

Step-by-step explanation:

since number 2 card was not replaced, we have;

probability of picking a second card, 3;

let S be number of sample space

n(S)= 4

n(3)= 1

Pr(3/2)= 1/3

(because since one was already chosen and n, the sample space would reduce)

Answer: I got 200

Step-by-step explanation: 14+14+5+5=38*2=76 Thats the front and back and then The sides are 6+6+5+5=22*2=44 then the top and bottom are 14 +14+6+6=40*2=80 then add that all up and 44+80+76=200 (Sorry if its a bit confusing to understand)
