Find the value of x.log 3 x = 4

A.) 7
B.) 12
C.) 27
D.) 81

Answers

Answer 1

Answer:

Hello from MrBillDoesMath!

Answer:

Choice D, 81

Discussion:

By log 3x = 4 I presume that "3" is the base not a multiplier of x. Assuming it is the base, then the equation is equivalent to

x = 3^4

= 81

This is Choice D.

Thank you,

MrB

If annual college tuition and fees cost $8675, room and board cost $2235, books are $1850, and other charges are $250 per year, what is the total cost for 1 year of attendance?

Answers

well we have to do 8675 + 2235 + 1850 + 250 which equals $13,010
so the answer is $13,010

13010 because all you need to do is add all of the numbers up

The pair of points (6,y) and (10,-1) lie on a line with a slope 1(over)4. What is the value of y?

Answers

The formula for Slope is m = $(y_2 - y_1)/(x_2 - x_1)$ where m is the slope and the x's and y's are your given coordinates. So, plug the given information into the formula and solve for y.

m = $(y_2 - y_1)/(x_2 - x_1)$ Plug in the given values
$(1)/(4)$ = $(-1 - y)/(10 - 6)$ Cross multiply
10 - 6 = -4 - 4y Subtract
4 = -4 - 4y Add 4 to both sides
8 = -4y Divide both sides by -4
-2 = y Swich the sides to make it easier to read
y = -2

Check your answer by plugging -2 back into the equation with the other values.

[tex] \frac{1}{4} [/tex] = $(-1 - (-2))/(10 - 6)$ Simplify the double negative
$(1)/(4)$ = $(-1 + 2)/(10 - 6)$ Simplify the numerator and denominator
$(1)/(4)$ = $(1)/(4)$

Since both sides equal each other, y = -2.

Use the formula to find the slope which is m= y2-y1 over x2-x2. The equation would look like 1/4= -1 -y over 10-6. First, you do the subtraction in the denominator and you get 4. The equation would look like 1/4=-1-y over 4.

Then, you multiply the 4 to both side in order to get rid of the fraction from the equation. You would then have 1=-1-y. You add -1 to both side and you would have 2=-y. Since the variable cannot be negative, you divide -1 from both side and get -2=y. Therefore the answer is y=-2.

Hope this helps.

Wheels are 1.25 inches in diameter covert the wheels diameter to feet

Answers

Wheels are 1.25 inches in diameter covert the wheels diameter to feet For this process to take place or in order to convert the said measurement to another such as inches to feet, we first have to determine the conversion values for the units asked. Thus,
1. 1 in = 0.0833333 foot

Solution.
a. 1.25 in x 0.0833333 ft / 1 in = 0.1041667 ft

Answer:

0.1041667 (approximation)

Step-by-step explanation:

divide that by 12
