well, if the room is 16' x 10', the area of it is simply 16*10 or 160 ft², now, we know that each ft² costs 5 bucks to carpet, so the total cost is just 160 * 5 = 800 bucks.
solve the equation. 2b+8-5b+3=-13+8b-9
Answer:
b=3Step-by-step explanation:
2b+8-5b+3=-13+8b-9
Combine like terms
-3b+11=8b-22
Subtract 11 from both sides:
-3b+11-11=8b-22-11
-3b=8b-33
Subtract 8b from both sides:
-3b-8b=8b-33-8b
-11b=-33
Divide both sides by -11:
-11b/-11=-33/-11
b=3

A local high school is raffle off a college scholarship to the students in its junior class, If a girl has a 0.55 chance of winning the scholarship and 154 of the juniors are girls, how many of the juniors are boys? (Assume that every junior has an equal chance to win.)
Answer: 126
Step-by-step explanation:
55% of student population is girls
if there are 154 girls then
0.55x = 154, where x represents school population
x=280
assuming the school only has boys and girls, anyone that's not a girl must be a boy, so
boys = 280 - 154 = 126.
if the school is not only boys and girls,
there will be 126 or less boys

Michael has collected 900 total coins. Of those
coins, 37% were minted in the year 1900 or
earlier. How many coins does Michael have that
were minted in 1900 or earlier?
Answer:
333 coins
Step-by-step explanation:
Simply multiply 37% by the total number of coins, 900:
37%(900)
= (37/100)(900)
= (900 / 100) * 37
= 9 * 37
= 333 coins
Also, optionally check this by dividing 333 by 900 to get 0.37:
333 ÷ 900 = 0.37 = 37%

Calculate the slope of a line with a run of 3 and a rise of 9.
Answer:
Slope = 3
Step-by-step explanation:
Slope is calculated as the "Rise/Run" of a straight line. The Rise is the change in the value of y, or the amount y changes per change in x. Run is the change in the x value. A line with a run of 3 and a rise of 9 is calculated as:
Rise/Run = 9/3 or 3
This means that the value of y will increase by 3 for every increase of 1 in the value of 3.
Slope in "m" in the slope-intercept form of a straight line equation: y = mx + b
The line y = 3x + 2 tells us the it has a slope of 3 and intercepts the y axis at x = 2.
Example points (y = 3x + 2)
(0,2)
(1,5)
(4,14)
Note that y changes by 12 when x changes by 4. Rise/Run = 12/4 or 3.

How much Water do you add to make each concentration 1% sugar syrup using 12 g sugar I saw the other answers were 33 but they were incorrect please help me
Answer:
1188 grams
Step-by-step explanation:
You want the 12g of sugar to be 1% of the whole solution.
So, say you add grams of water. The solution will be composed of 12 grams of sugar and grams of water, for a total of grams.
So, the ratio "sugar/total" will be
and we want this ratio to be 1%, i.e. 1/100:
Multiply both sides by 100 and to get
Subtract 12 from both sides:
So, a solution composed of 1188 grams of water and 12 grams of sugar will be 99% water and 1% sugar.
Answer: 1188 grams of water
Step-by-step explanation:
Sugar = 1% = 12
Whole = 100% = 12·100 = 1200
Water = 99% = 1200 - 12 = 1188
You Need 1188 Grams Of Water To Make The Solution 1% Sugar

4) The nth term of a sequence is 2n? (1) Find the 4th term of the sequence. (ii Is the number 400 a term of the sequence? Give reasons for your answer.
pls answer fast
Answer:
i) 8
ii) yes 400 is a value in the sequence as the nth term would be 200 for that, 400 is also divisible by 2, and as 2 is the coefficient of n, 400 can be a value in the sequence.
Step-by-step explanation:
for n as term number:
n = 4
2n = 8
i) 8 is the fourth term
for n as unknown:
2n = 400
400/2 = n
200 = n
ii) yes 400 is a value in the sequence as the nth term would be 200 for that, 400 is also divisible by 2, and as 2 is the coefficient of n, 400 can be a value in the sequence.

Suppose that a duck swam 22.5 kilometers in 5 hours at a constant speed how far did the duck travel
Answer:
4.5 = x
Step-by-step explanation:
Given:
22.5 = 5x
(we need to find out what x is)
22.5 / 5 = 4.5
meaning that the duck traveled at 4.5 kilometers per hour.
Check:
4.5 x 5 = 22.5
Find the area 9ft 15ft 11ft
Answer:
[tex]A_{total} = 132\ ft^2[/tex]
Step-by-step explanation:
Step 1: Determine the area of the rectangle
[tex]A = l * w[/tex]
[tex]A = 9\ ft * 11\ ft[/tex]
[tex]A = 99\ ft^2[/tex]
Step 2: Determine the area of the triangles
[tex]A = \frac{h * b}{2}[/tex]
[tex]A=\frac{(15\ ft - 9\ ft)*(11\ ft / 2)}{2}[/tex]
[tex]A=\frac{6\ ft * 5.5\ ft}{2}[/tex]
[tex]A = 16.5\ ft^2[/tex]
Since we found only one of the right triangles we need to multiply the area that we got by 2 to get the total triangle area.
[tex]A = 16.5\ ft^2 * 2[/tex]
[tex]A = 33\ ft^2[/tex]
Step 3: Determine the total area
[tex]A_{total} = 99\ ft^2 + 33\ ft^2[/tex]
[tex]A_{total} = 132\ ft^2[/tex]
Answer: [tex]A_{total} = 132\ ft^2[/tex]

Answer:
(d) 2x +y = 8
Step-by-step explanation:
The answer choices are shown in "standard form," so the comparison to the given equation is easier if it is written in standard form. Add 2x to both sides:
2x +y = 5 . . . . . . given equation in standard form
The other equation in a system with no solution will look like this, but will have a different constant:
2x +y = 8 . . . . . . does not intersect the given equation
_____
Additional comment
All of the other equations shown will intersect the given equation. One way to show this is to use the given equation to substitute for y in the answer choices:
a: 2x -(-2x+5) = 8 ⇒ 6x -5 = 8 . . . one solution: x=13/6
b: x +2(-2x+5) = 8 ⇒ -3x +10 = 8 . . . one solution: x=2/3
c: x -2(-2x+5) = 8 ⇒ 5x -10 = 8 . . . one solution: x=18/5
d: 2x +(-2x+5) = 8 ⇒ 5 = 8 . . . no solution
For what values of x will the function f(x) = 7x ^ 2 + 27x - 4 equal zero?
In quadratic equation, x = 1/7, -4 are the values of x will the function f(x) .
What in mathematics is a quadratic equation?
A quadratic equation is a second-order polynomial equation in one variable using the formula x = ax2 + bx + c = 0 and a 0. The fundamental theorem of algebra ensures that it has at least one solution because it is a second-order polynomial problem.
f(x) = 7x² + 27x - 4
= 7x² + ( 28 - 1 )x - 4
= 7x² + 28x - x - 4
= 7x( x + 4) -1( x + 4 )
= (7x - 1 ) ( x + 4)
7x - 1 = 0
x = 1/7
x + 4 = 0
x = -4

A bicycle has a listed price of $808.98 before tax. If the sales tax rate is 8.75%, find the total cost of the bicycle with sales
tax included.
Round your answer to the nearest cent, as necessary.
Answer:
$879.76575 --> $880
Step-by-step explanation:
$808.98 × 0.0875 = $70.78575 <-- this represents the additional sales tax
$808.98 + $70.78575 = $879.76575 <-- add sales tax to original price

Let x = NK
7/13 = x/56 Notice that the longest side of the small trapezoid is the denominator of the fraction on the left. That means that the longest side of the large trapezoid must also be the denominator of that fraction on the right.
Cross multiply
13x = 7*56 Combine the right
13x = 392 Divide by 13
x = 392/13
x = 30.15
NK = 30.15
Answer:
30.2
Step-by-step explanation:
IJ is proportional to MN, which would give us 13/56. Next, JG is proportional to NK, which would give us 7/x. So, 13/56 = 7/x, 13x = 392, x = 30.15, which rounds to 30.2

Find the perimeter of the figure to the nearest hundredth. pls help
Answer:
50.26 in
Step-by-step explanation:
First you need the circumference of half of a circle.
Circumference = diameter x pi. The radius is 9, so the diameter is 18. 18 * 3.14 = 56.52. But you need half of that, so 56.52 / 2 = 28.26
Then add the other 3 sides
28.26 + 5 + 12 + 5 = 50.26
