LET ME KNOW ASAP

A Baker Puts A Chocolate Cake In The Oven To Bake For 30 Minutes. Let F(t) = 0.25 + 65 Be The Temperature

Answers

Answer 1

Answer:

Options (1) and (5)

Step-by-step explanation:

Given function 'f' representing the relation between temperature of the oven after 't' minutes is,

f(t) = 0.25t² + 65

Option (1).

f(0) means that when the cake was placed in the oven, its temperature was 65°.

True.

f(0) = 0 + 65 = 65

Option (2).

To find the temperature after 15 minutes, we need to find 't' when f(t) = 15

False.

We have to find the value of f(15) to find the temperature of the oven after 15 minutes.

Option (3).

Temperature of the cake was 81° F when it was kept in the oven for 8 minutes.

Given statement is False.

It should be represented by,

f(8) = 81

Option (4).

After 10 minutes,the temperature of the cake was 71.25 degree F.

False.

By putting t = 10 in the function,

f(10) = 0.25(10)² + 65

       = 25 + 65

       = 90° F

Option (5).

The temperature of the cake when the baker takes it out of the oven, can be represented by,

f(30) = 290

True.

f(30) = 0.25(30)² + 65

       = 225 + 65

       = 290

If you buy a car for $5,000 and you put down $1,500 for a down payment, how much equity will you have in the car?

A. $1,500
B. $5,000
C. $6,500
D. $3,500

Answers

Answer:

C.$6,500

Step-by-step explanation:

Because you payed $5,000 for a car and $1,500 more for a down payment, so we would have to add.

$5,000 (cost of car) + $1,500 (cost of down payment) = $6,500 (total pay)

The difference in the price of 2 TVs is $217.45. If one TV costs $450.50, which of the answer choices could represent the price of the other TV?
A.) $677.95
B.) $657.95
C.)$233.05
D.) $223.05

Answers

Answer:

C.

Step-by-step explanation:

450.50 - 217.45 = $233.05 :)

The cost of another TV is $677.95

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

The difference in the price of 2 TVs is $217.45.

One TV costs = $450.5

So, 450 -  Another Tv Cost = 217.45

Another Tv Cost = 217.45+ 450.5

Another Tv Cost = $677.95

Hence, the cost of another TV is $677.95

What is an equation of the line that passes through the point (−5,−1) and is parallel to the line 4x+5y=45?

Answers


This gives you, 4x + 5y = -25 as your final answer.

Answer:

y = -4/5x - 5

Step-by-step explanation:

4x + 5y = 45

we need to write it in slope intercept form, so:

5y = -4x + 45

y = -4/5x + 45/5

y = -4/5x + 9

The line is parallel so the slope will be -4/5x, point ( -5 -1 )

y = mx + b

-1 = -4/5(-5)+b

-1 = 4 + b

-1 - 4 = b

-5 = b

y = -4/5x - 5

Write and solve an equation for this situation. In one baseball season, Peter hit twice the difference between the number of home runs Alice hit and 3. Altogether, they hit 9 home runs. How many home runs did each player hit that season? Let h represent Alice's home runs. Alice hit home runs. Peter hit home runs.

Answers

Answer:

Y=8

Step-by-step explanation:

The difference between the number Alice hit and 6 is X - 6.  Twice that would be 2(X-6).  So Y = 2(X-6).  We also know that X + Y = 18 so we have 2 equations:

 

Y = 2(X-6)

X+Y = 18

 

Let's take the second equation and solve for Y in terms of X

 

Y = 18 - X

 

Now take that result and substitute that back into the first equation that starts with Y, because now you know that Y is also equal to 18 - X, now you have:

 

18 - X = 2(X - 6)

 

Let's solve for X

 

18 - X = 2X - 12

18 - 3X = - 12

- 3X = - 30

X = 10 <--number of home runs Alice Hit

 

That leaves us with Y = 8  <---number of home runs Peter hit

 

Go back to the original question and make sure the answer fits.  The difference between 10 and 6 is 4 and twice that is 8, the number Peter hit.  10 + 8 = 18.  Good to go!

Felipe es encargado de un laboratorio de informática y sabe que los alumnos frecuentemente ocupan memorias USB, con el fin de apoyar a los alumnos compra 100 memorias que a precio de mayoreo le salen a $92 cada una. Felipe vende cada USB en $100 ¿cual es el porcentaje de ganancia que obtiene Felipe por la venta de cada memoria?

Answers

Explicación paso a paso:

Cantidad total de USB comprado = 100

Precio al por mayor = $ 92

Costo de 100 memorias USB = 100 * $ 92 = $ 9,200

Si vende cada memoria USB por $ 100 cada una a precio minorista, la cantidad total en 100 USB será;

100 * $ 100 = $ 10,000

% beneficio = beneficio / precio de coste * 100%

Beneficio = precio de venta - precio de costo

Beneficio = $ 10,000 - $ 9,200

Beneficio = $ 800

% de beneficio = 800/9200 * 100

% de beneficio = 800/92

% beneficio = 8,696%

De ahí que el porcentaje de beneficio que obtiene felipe por cada venta de cada recuerdo es del 8,696%
