Answer:

f(6) = 53

Step-by-step explanation:

f(x) = 10x - 7

We want to find f(6)

To do so simply substitute 6 for x in the equation

Equation: 10x - 7

x = 6

f(6) = 10(6) - 7

multiply 10 and 6

f(6) = 60 - 7

subtract

f(6) = 53

Answer:

$f(x)=53$

Step-by-step explanation:

For $f(x)=10x-7\\$ substitute x for 6

$10\cdot 6=60\\60-7=53$

$f(6)=53$

Alice wants to buy 3 pounds of veal at the grocery store, but the scales at the store only show weight in kilograms. If one kilo

kaheart [24]

Alice should buy 1.36 kilograms of veal.

Step-by-step explanation:

Given,

According to store's scale;

2.20 pounds = 1 kilogram

1 pound = $\frac{1}{2.20}\ kg$

As Alice wants to buy 3 pounds, therefore,

3 pounds = $\frac{1}{2.20}*3\\$

$3\ pounds = \frac{3}{2.20}\\3\ pounds = 1.36\ kg$

Alice should buy 1.36 kilograms of veal.

The rate of change of atmospheric pressure P with respect to altitude h is proportional to P, provided that the temperature is c

jonny [76]

Answer:

$P = 101.5 e^{-0.00015h}$

Step-by-step explanation:

dP/dh = kP

dP/P = k dh

ln P = kh + C

Now, using the points given,

ln 101.5 = C, so C = 4.62

ln 87.3 = k*1000 + 4.62

k = -0.00015

So, we have

ln P = -0.00015 h + ln 101.5

P = 101.5 e^(-0.00015h)

In 1990, the price of a gallon of unleaded gasoline was $1.37. In 1998, it was $1.02 per gallon. What is the decrease expressed

mojhsa [17]

The decrease is 35c

Q= X/100 of $1.37 = 0.35

1.37x/100 = 0.35

1.37x = 35 then divide each side by 1.37

Result is 25.5474453 percent, round up to nearest tenth.
Answer is 25%

How is the area of a parallelogram related to the area of a circle?

sergejj [24]

Answer:

The area of a parallelogram is base times height. Since the area of that rectangle is twice the area of the circle, then the area of the circle is half the base times the height. It will be half of 2πr· r. The area of the circle will be πr2.
