Answer:

T4 = 162 T5 = 486 T6 = 1458

Explanation:

the pattern is multiply the previous number by 3

so 6 x 3 = 18

18 x 3 = 54

54 x 3 = 162 and so on.

Principal is 15000 interest rate is 8.75 simple interest is 5425.00 what is the time

stellarik [79]

in simple interest, I=PRT

I=interest

P=principal

R=rate in decimal form

T=time in years usually, but could be months or weeks, dunno

I'm assuming that the 8.75 is 8.75% or 0.0875 in decimal

I=PRT

we know I, P, and R, so solve for T

I=PRT, divide both sides by PR

I/(PR)=T

subsitute

I=5425.00, P=15000, R=0.0875

I/(PR)=5425.00/(15000*0.0857)=4.133333333=T

so the time is 4.13333333 units of time

Alexa has some dimes and some quarters. She has a minimum of 28 coins worth a maximum of $5.05 combined. If Alexa has 17 quarter

Lerok [7]

Answer:

There are no possible solutions

Step-by-step explanation:

Given:

Minimum number of coins Alexa has =28 coins

Number of quarters Alexa has = 17 quarters

Total amount in coins = $5.05 = 505 cents

Let number of dimes be = $x$ coins

So we can have two inequalities.

1) Total number of coins

$x+17\geq28\\$ [Since minimum number of coins=28]

2) Total value of coins

$10x+(25)(17)\leq505$ [As 1 dime=10 cents and 1 quarter=25 cents]

$10x+425\leq505$

Solving inequality (1)

Subtracting both sides by 17.

$x+17-17\geq28-17$

∴ $x\geq 11$

Solving inequality (2)

Subtracting both sides by 425.

$10x+425-425\leq505-425$

$10x\leq 80$

Dividing both sides by 10.

$\frac{10x}{10}\leq \frac{80}{10}$

∴ $x\leq 8$

On combining both solutions

$x\geq 11$ and $x\leq 8$ ,

we see that there are no possible solutions as number of dimes cannot be ≥11 and ≤8 at the same time.

Question 1 options:

Musya8 [376]

Answer:

x = 1.56 or x = -2.56

Step-by-step explanation:

From the equation;

x2 +x − 4 = 0

a = 1 , b = 1, and c = -4

x = (-b ± √(b² -4ac))/2a

= (-1 ± √(1²- 4×1×-4))/2

= ( -1 ± √(17)/2

= (-1 ± 4.12)/2

= (-1 + 4.12)/2 or (-1 - 4.12)/2

<u>x = 1.56 or x = -2.56</u>

Hypotenuse of 15 and opposite of 12For this triangle what is the cos

muminat

<h3>Given</h3>

right triangle with side "a" = 12 and hypotenuse "c" = 15

cos(∠A)

<h3>Solution</h3>

The Pythagorean theorem tells you

... b = √(c² - a²) = √(225 - 144) = √81 = 9

The definition of the cosine tells you

... cos(A) = b/c = 9/15

... cos(A) = 3/5 . . . . . . reduce the fraction
