What is the value of this expression when a=3 and b= -2? (3a (exponent) -2 b (exponent) 6) exp. -2 ___________________________ (2a (exponent) -1 b (exponent) 5) Its all one equation!

Answers

Answer 1

Answer:

I looked online to find the equation well written, but i could not find it, so i will guess that the equation is:

[tex]\frac{3*a^{-2} - 2*b^{-6}*e^{-2}}{2*a^{-1}*b^{5}}[/tex]

Now we want to find the value of this equation when:

a = 3 and b = -2

So we can just replace these values in the equation, each a is replaced by a 3, and each b is replaced by a -2.

The equation becomes.

[tex]\frac{3*3^{-2} - 2*(-2)^{-6}*e^{-2}}{2*3^{-1}*(-2)^{5}} = 44.3[/tex]

What is the simple Intrest to 1,250 at 4.5% for 2 years

Answers

Answer:

1,362.50 Dollars

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 4.5%/100 = 0.045 per year.

Solving our equation:

A = 1250(1 + (0.045 × 2)) = 1362.5

A = $1,362.50

Challenge You have 2 different savings accounts. For Account​ A, the simple interest earned after months is ​$. For Account​ B, the simple interest earned after months is ​$. If the interest rate is ​% for Account A and ​% for Account​ B, how much is the principal in each​ account? Which account earned you the most interest the first​ month? Explain your answer.

Answers

Answer and Step-by-step explanation:

The computation is shown below;

As we know that

The simple interest is

Simple interest = Principal × rate × time

For Account A, the principal would be

2 = Principal × 3.2% × 3

So, the principal is $20.83

For account B, the principal would be

38.50 = Principal × 2.2% × 30

So, the principal is $58.33

Now the interest for both the accounts are as follows

For account 1

= $20.83 × 3.2%

= $0.67

And, for the account 2

= $58.33 × 2.2%

= $1.28

As it can be seen that the account 2 has the highest interest

The same is to be considered

Como se resuelve un circuito en serie matemáticamente?

Answers

Answer:

Step-by-step explanation:

En un circuito en serie, toda la corriente pasa a través de cada uno de los resistores, uno a la vez. Esto significa que cada resistor contribuye su resistencia completa al circuito. Si conoces el valor individual de cada resistencia, solo súmalos para encontrar la resistencia total del circuito.

In a series circuit , all of the current passes through each of the resistors, one at a time. This means that each resistor contributes its full resistance to the circuit . If you know the individual value of each resistor, just add them together to find the total resistance of the circuit .

Ruben brought 2 large popcorn buckets and 4 small drins for 20. Lucia bought 2 large popcorn buckets and 2 small drinks for 14.What was the cost of the large popcorn and the small drinks

Answers

Answer:

Cost of large popcorn = 4

Cost of small drinks = 3

Step-by-step explanation:

Given that :

Let cost of large popcorn = x

Cost of small drinks = y

Cost of 2 large popcorn and 4 small drinks

2x + 4y = 20

2x + 2y = 14

x + 2y = 10 - - - (1)

x + y = 7 - - - (2)

Subtract :

2y - y = 10 - 7

y = 3

Substitute y = 3 into (2)

x + 3 = 7

x = 7 - 3

x = 4

Hence,

Cost of large popcorn = 4

Cost of small drinks = 3

Answers

Answer:

Tammy

Step-by-step explanation:

Tammy read 7.75 hours last month. Kelley read 7.69 hours

Jim read 7.075 hours.

We would arrange the hours of reading from smallest to the highest

7.075, 7.69, 7.75

The person who spent the most time reading is the person with the highest number of hours that was spent reading. This person is Tammy.

Therefore, person who spent the most time reading is Tammy because she read for 7.75 hours.

The person who spent the most time reading is Tammy.

Tammy read 7.75 hours last month reading.Kelley read 7.69 hours reading.Jim read for 7.075 hours.

Therefore, from the decimals given, we can see that the highest is 7.75 hours that was used by Tammy.

Glen is making accessories for the soccer team. He uses 536.25 inches of fabric on headbands for 37 players and 2 coaches. He also uses 325.97 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player?

Answers

Answer:

For Headband

Each player used 13.75 inches of fabric

For Wristband

Each player used 8.81 inches of fabric

Step-by-step explanation:

Glen is making accessories for the soccer team.

For head bands :

He uses 536.25 inches of fabric on headbands for 37 players and 2 coaches.

Let the inches of fabric used be represented by x

536.25 = 37 x + 2x

536.25 inches = 39x

x = 536.25 inches/39

x = 13.75 inches of fabric.

For Wristbands

He also uses 325.97 inches of fabric on wristbands for just the players.

Let y represent the inches of fabric used for players

We have 37 players

Hence:

325.97 = 37y

y = 325.97 inches/37

y = 8.81 inches

Therefore:

For Headbands

Each player used 13.75 inches of fabric

For Wristbands

Each player used 8.81 inches of fabric

Engineering=120+22x; Business=105-4x;Biology=98+6x; how many years will it be before Engineering has twice as many students as Business; how many years will it be before Engineering has twice as many students as Biology.

Answers

Answer:

Step-by-step explanation:

Given

Engineering=120+22x;

Business=105-4x;

Biology=98+6x;

If Engineering has twice as many student as biology then,;

120+22x = 2(98+6x)

Expand

120+22x = 196+12x

Collect like terms

120-196 = 12x-22x

-76 = -10x

x = -76/-10

x = 7.6

Hence it will take like 7 and a half years before engineering has twice as many student as biology

A recipe for chicken marinade says, ''Mix 3 parts oil with 2 parts soy sauce and 1 part orange juice. ''if you need 42 cups of marinade in all,how much of each ingredient should you see?

Answers

Answer:

Parts of oil in 42 cups of marinade = 21 cups

Parts of soy sauce in 42 cups of marinade = 14 cups

Parts of orange juice in 42 cups of marinade = 7 cups

Step-by-step explanation:

Given that:

Parts of oil = 3

Parts of soy sauce = 2

Part of orange juice = 1

Total cups of marinade = 42

To find:

How much of each ingredient should be there ?

Solution:

This problem can be solved by taking the ratio of ingredients into account.

The ratio is:

Oil : Soy Sauce : Orange Juice = 3 : 2 : 1

So, we can let the parts of oil = [tex]3x[/tex]

Parts of soy sauce = [tex]2x[/tex]

Parts of orange juice = [tex]x[/tex]

As per the question statement:

[tex]3x+2x+x=42\\\Rightarrow 6x=42\\\Rightarrow x =7[/tex]

So, parts of oil in 42 cups of marinade = 3 [tex]\times[/tex] 7 = 21 cups

Parts of soy sauce in 42 cups of marinade = 2 [tex]\times[/tex] 7 = 14 cups

Parts of orange juice in 42 cups of marinade = 7 cups

Tasks: Find the price per pound of each turkey. Stater Bros.: Ralphs: Food for Less: Which store has the best price? Store name:

Answers

Answer: See explanation

Step-by-step explanation:

At Stater Bros., she found an 18 lb turkey for $21.42. The cost per pound will be:

= $21.42 / 18

= $1.19 / lb

At Ralphs, she found a 20 lb turkey for $24.20. The cost per pound will be:

= $24.20 / 20

= $1.21 / lb

At Food for Less, she found a 17 lb turkey for $18.36. The price per pound will be:

= $18.36 / 17

= $1.08 / lb

Based on the explanation, Food for Less has the best price as it's cheaper than others.
