Answer:

$A = P(1 +\frac{r}{n})^{nt}$

P = 4100

r = 2.25% = 0.0225

n= 2

t= 12

$A = 4100(1 + \frac{0.0225}{2})^{24}\\$

$= 4100 *1.01125^{24}\\\\= \$ 5362.76$

Mark Ronnie and Lisa bought a 75 inch curved 4000 television.Lisa put 650 more than Mark had.Mark had twice as much and then Ron

Alexeev081 [22]

So since you gave all of the equations of everyone's amount that they put in, it saves some work.

Let's add up everyone's contribution and then solve for x:

$(2x+500)+x+(650+2x+500)$

Then since we know the television costs $2,000, we can set this expression equal to that and simplify terms. Then we can solve for x:

$5x+1,650=2000$

$5x=350$

$x=70$

So since Ronnie put in 'x', we can say that Ronnie paid $70.

Since Mark put in '2x + 500', we can plug in 70 for x to find that Mark paid $640.

And since Lisa put in '650 + 2x + 500', we can plug in 70 for x again to find that Lisa paid $1,290.

a triangular sail has a base length of 2.5 meters. the area of the sail is 3.75 square meters. how tall is the sail?

Alik [6]

Area=1/2 times height times base
base=2.5
area=3.75
subsitute

3.75=1/2 times height times 2.5
multiply both sides by 2 to get rid of fraction
7.5=height itmes 2.5
divide both sides by 2.5
3=height

sail is 3 meters tall

Calcula el radio de un cilindro que tiene 8 cm de altura y un volumen de 122 cm cúbicos

kondaur [170]

Answer:

$\huge{ \boxed{ \sf{2.20 \: cm}}}$

Step-by-step explanation:

$\star{ \sf{ \: altura \: de \: un \: cilindro\: = \: 8 \: cm}}$

$\star{ \sf{ \: volumen \: de \: un \: cilindro = 122 \: cm \: cúbicos}} \:$

$\star { \sf{ \: encontrar :radio \: de \: un \: cilindro }}$

$\boxed{ \sf{ \: Volume \: of \: a \: cylinder \: = \: {\pi \: radius}^{2} \: height}}$

$\mapsto{ \sf{122 \: = \: ( \frac{22}{7} )r \: ^{2} \: \times \: 8}}$

$\mapsto{ \sf{122 = 25.14 \: {r}^{2} }}$

$\mapsto{ \sf{25.14 \: {r}^{2} = 122 }}$

$\mapsto{ \sf{ \frac{25.14 \: {r}^{2} }{25.14} = \frac{122}{25.14}}}$

$\mapsto{ \sf{ {r}^{2} = 4.85 \: cm}}$

$\mapsto{ \sf{r = 2.20 \: cm}}$

radio de un cilindro = 2.20 cm

SAT scores probability 1

fredd [130]

Answer:

a. 81.5%

Step-by-step explanation:

The z-score for 400 is ...

Z = (X -μ)/σ = (400 -500)/100 = -1

The z-score for 700 is ...

Z = (700 -500)/100 = 2

The empirical rule tells you that 68% of the distribution is within ±1σ of the mean, and 95% is within ±2σ of the mean. Half of that first number is in the range Z = -1 to 0, and half that second number is in the range Z = 0 to +2. So, the probability you want is ...

(1/2)(68%) + (1/2)(95%) = 81.5% . . . . matches choice A
