A bathroom is 6 ft 5in long and 4 ft 3in wide what is the area of the bathroom in square feet. I need work with the answer

Answers

Answer 1
Answer: you just multiply the sides. 
Firstly, it's easier if you convert both measurements to inches.
so you'd do 6 x 12 = 72 , 72 + 5 = 77 inches
and 4 x 12 = 48 , 48 + 3 = 51 inches.

Then you multiply the sides, so:
77 x 51 = 3927 inches
then you divide by 12 to get how many feet and inches it is
3927/12 = 327 feet and 4 inches

One circle has a diameter of 6 inches. A second, larger circle has a diameter that is four times the diameter of the first circle. What is the ratio of the area of the smaller circle to the larger circle?

Answers

The area of a circle:
A=\pi r^2
r - the radius, which is equal to half the diameter d

The first circle:
d_1=6 \nr_1=(6)/(2) = 3 \nA_1=\pi * 3^2=9\pi

The second circle:
the second circle has a diameter that is four times the diameter of the first circle.
d_2=6 * 4=24 \nr_2=(24)/(2)=12 \nA_2=\pi * 12^2 = 144\pi

The ratio of the area of the smaller cirlce to the area of the larger circle:
(A_1)/(A_2)=(9 \pi)/(144 \pi)=(9)/(144)=(9 / 9)/(144 / 9)=(1)/(16)

The ratio is 1:16.

I need to factor 5a^2 + 7a + 6b^2 - 4b  but I can't figure it out.......could it possibly be prime?

Answers

I kind of forgot how to do it but here is what I know so far : first you separate the two parts into (5a^2 + 7a) + (6b^2-4b). This process is called grouping. Now you find the greatest common factor in both of them which later your equation will be a(5a + 7) +2b(3b - 2). That is all I can remember so hope that helped

A store has apples on sale for $3.00 for 2 pounds. How many apples can you buy for $9.00? I got about 18 apples, is that considered correct?

Answers

No.

Bonnie and some friends went to an amusement park. They bought rve of thesame lunches and 3 desserts and spent a total of $60.25 on the food. Eachdessert costs $5.25 less than one of the lunches.a. Detine a variable: Write an equation that can be used to find the cost oflunch.b. Solve the equation to find the cost of a lunch.en5.2

Answers

Let the variable be the cost of the lunch: x

so they bought 5 lunches: 5x
deserts are cheaper than lunches; they cost:
x-5.25
So together they paid:
5x+3*(x-5.25)=60.25

(we know how much they paid, so we can make an equation)

Let's remove the bracket:
5x+3*x-15.75=60.25

8x-15.75=60.25//we add 15.75 to both sides:
8x=76
and divide by 8:
x=9.5

So each lunch costs 9.5 dollars!


What are the slope, m, and y-intercept, (0, b), of the line described bythe equation 3x + 6y=12?
Write an
anation in
I have no idea how to do this I need help

Answers

Answer:

\large \boxed{m = -(1)/(2);\text{ y-intercept = 2}}}

Step-by-step explanation:

The slope-intercept form of an equation is

y = mx + b, where

m = the slope and

b = the y-intercept

We must solve your equation for y.

It will then be in the slope-intercept form.

\begin{array}{rcll}3x + 6y  & = & 12 & \n6y & = & 12 - 3x & \text{Subtracted 3x from each side}\ny&= &2 -(1)/(2)x& \text{Divided each side by 3}\n\mathbf{y} &= & \mathbf{-(1)/(2)x + 2}& \text{Rearranged terms}\n\end{array}\n\n\large \boxed{\mathbf{m = -(1)/(2);\textbf{y-intercept = 2}}}

The diagram below shows the equation of your graph with m = -½ and the y-intercept at (0, 2)
