-12(5/6a-7/8)+1/14(3 1/2a-1 2/5)
Answers
First change mixed fractions to be full fractions
-12(5/6 a -7/8) + 1/14 (7/2 a - 7/5)
Now multiply out
-12(5)/6 a -12(-7)/8) + 7/14(2) a -7/14(5)
-60/6 a + 84/8 + 7/28 a -7/70
-10a + 10.5 + 1/4a - 1/10
-10a + 0.25a +10.5 -0.1
-9.75a + 10.4
*if this =0 and you need to solve for a then
9.75a=10.4
a= 10.4/9.75
a=16/15
The perimeter of a rectangle is 20 feet. The width is 4 feet less than the length. Find the dimensions of the rectangle. Then find its area.
Answers
Answer:
length = 7 ft
width = 3 ft
area = 21 sq ft
Step-by-step explanation:
let l = length
let l - 4 = width
2l + 2(l - 4) = 20
2l + 2l - 8 = 20
4l = 28
l = 7
w = 3
Area: 7 x 3 = 21

<GHI = 135 degrees
Step-by-step explanation:
(3x + 12) + (x + 4) = 180
4x + 16 = 180
4x + 16 - 16 = 4x
180 - 16 = 164
4x = 164
4x / 4 = x
164 / 4 = 41
x = 41
3 * 41 + 12
3 * 41 = 123
123 + 12 = 135

If another sample of size 100 is taken, what is the probability that its sample mean will
be greater than 2.56 in?
Answers
Answer:
I don't know the answer to this but
Suppose we draw a sample of size n=16 from this population and want to know how likely we are to see a sample average greater than 22, that is P( > 22)? So the probability that the sample mean will be >22 is the probability that Z is > 1.6 We use the Z table to determine this: P( > 22) = P(Z > 1.6) = 0.0548.

That being said we can create equation
5x + 40 = 115
now we solve for x
step 1 subtract 40 from each side
40 - 40 cancels out
115 - 45 = 75
now we have 75 = 5x
step 2 divide each side by 5
5x/5=x
75/5=15
we're left with x = 15

You can buy 12 cookies for $4. What is the unit rate for the cost of each cookie?
Answers
Answer:
$0.33 per cookie
Step-by-step explanation:
The unit rate (cost per cookie) is
$4
---------------- = $0.33 per cookie
12 cookies
Answer:
Roughly $0.34
Step-by-step explanation:
Set up an equation:
Variable x = cost of one cookie
12cookies/$4 = 1cookie/x
12/4 = 1/x
Cross multiply
12 × x = 4 × 1
12x = 4
Divide both sides by 12
12x ÷ 12 = 4 ÷ 12
1x = 4/12
x = 0.333333
x = is about $0.34

[tex]\large\boxed{A = 12.5 \text{ units}^{2}}[/tex]
Find the area of the shape using the formula for the area of a trapezoid:
A = 1/2(b1 + b2) · h
Where:
b1 = base 1
b2 = base 2
h = height
A = area
Plug in the given bases and height:
A = 1/2(7.5 + 2.5) · 2.5
Simplify:
A = 1/2(10) · 2.5
A = 5 · 2.5
A = 12.5 units²

What is the solution set of the equation?
[tex]\sqrt{x} -18+9x=x[/tex]
Answers
9514 1404 393
Answer:
x ∈ {2.07014981016}
Step-by-step explanation:
The equation can be rewritten as ...
√x = 18-8x
x = 324 -288x +64x²
64x² -289x +324 = 0
x = (289 ±√577)/128 ≈ {2.07015, 2.44548}
Since √x must be positive, we know that ...
18 -8x ≥ 0
x ≤ 18/8 = 2.25
The larger of the above solutions is extraneous, so the solution set is ...
x ∈ {(289 -√577)/128} ≈ {2.07015}
