What is the area❓ No links or troll answers you’ll be reported
Answer:
103
Step-by-step explanation:
Find the area of the rectangle on the top
A = 7*13 = 91
Now find the area of the rectangle on the bottom
13 - (5+5) = 3
11-7 = 4
The dimensions of the bottom rectangle are 3 by 4
A = 3*4 = 12
The total area is 91+12 = 103

What does n equal in 6(2n – 3) – 2(6n + 1) = 10n?.
Answer:
n = -2
Step-by-step explanation:
6(2n - 3) - 2(6n + 1) = 10n
multiply the brackets
6*2n - 6*3 - 2*6n - 2*1 = 10n
12n - 18 - 12n - 2 = 10n
add or subtract the like terms
0 - 20 = 10n
shift 10 to the right hand side .REmember when u shift multiplication changes to division.
-20 / 10 = n
-2 = n
Answer:n=-2
Step-by-step explanation:
12n-18-12n-2=10n
-20=10n
n=-2
Which functions are even?
Answer:
Step-by-step explanation:
First function: even, because both exponents are even; graph is symmetric about the x-axis
Second function: mixture of even and odd exponents: not even
Third function: This is the square root of x - 2; not even
Fourth function: |x| is even; graph is symmetric about the x-axis
Store a sells fabric for 3.00 per yard Store b sells packages of fabric for 3.00 The cost of fabric at either can be modeled by the function c(t)=3t where t is the number of yards of fabric at store a and t is the number of packages of fabric at store b The domain of c(t)=3t is all real numbers
Answer:
[tex]0 \le t < \infty[/tex]
Step-by-step explanation:
Given
[tex]c(t) = 3t[/tex]
Required
The domain
From the question, we understand that t represents number of yards/packages (depending on the store)
This means that:
[tex]t \ge 0[/tex] ---- the start value
[tex]t < \infty[/tex] --- the end value
Rewrite [tex]t \ge 0[/tex] as [tex]0 \le t[/tex]
So, we have: [tex]0 \le t[/tex] and [tex]t < \infty[/tex]
Hence, the domain is: [tex]0 \le t < \infty[/tex]
PLZ HELP A pantry contains cans of several different types of soup.
vegetable beef 22
black bean 3
chicken tortilla 12
cream of mushroom 1
minestrone 4
What is the probability that a randomly selected can will be black bean soup?
Write your answer as a fraction or whole number.
Answer:
3/42 or 1/14 if they have you reducing the number
Step-by-step explanation:
There are only 3 cans of black bean soup in the whole pantry. 3 is our numerator.
The denominator will be the total number of cans in the pantry, so
22 + 3 + 12 + 1 + 4 = 42
If you took a can of soup out of the pantry 42 times, 3 times it would be black bean soup

Find the total area for the composite figure below
Area of triangle + rectangle
= 1/2× 9×4 + 9×6
= 18+ 54
= 72
Answer:
72 units²
Step-by-step explanation:

Construct the 95% confidence interval estimate of the mean VAS score for patients given the magnet treatment. Find the Standard error and critical value. construct the 95% confidence interval estimate of the mean VAS score for patients given the sham treatment. You may do the shortcut.
Answer:
(3.442 ; 6.558)
Step-by-step explanation:
Given :
Mean score after patient is given the magnet treatment :
Mean score, xbar = 5
Standard deviation, s = 2.4
Sample size, n = 20
The confidence interval :
Mean ± margin of error
Margin of Error = Tcritical * standard error
The critical value at 95%, df = 20 - 1 = 19
Tcritical = 2.093 (T-student distribution)
The standard error = s/√n = 2.4 / √20 = 0.5367
The margin of error = 2.903 * 0.5367 = 1.558
The confidence interval :
Xbar ± Margin of error
5 ± 1.558
(3.442 ; 6.558)

Answer:
(√5)/2
Step-by-step explanation:
Of the several ways I can think of to do this, using a graphing calculator is about the easiest. It shows the minimum to be ...
f(1) = √1.25 = (√5)/2
__
Using the distance formula, you have ...
f(x) = √((x -(-2))² +((x² +2)-5/2)²)
f(x) = √(x² +4x +4 +x⁴ -x² +1/4) = √(x⁴ +4x +17/4)
The minimum is found where the derivative is zero.
f'(x) = (2x³ +2)/√(x⁴ +4x +17/4) = 0
x³ = -1 . . . . . f'(x) is zero when the numerator is zero
x = -1 . . . . . cube root
Then the minimum value of f(x) is ...
f(-1) = √(x⁴ +4x +17/4) = √((-1)⁴ +4(-1) +17/4) = √(1 -4 +17/4) = √(5/4)
f(-1) = (√5)/2 . . . . minimum value of f(x)
__
The graph shows f²(x) in red and its minimum of 1.25 = 5/4. The curve (x, x²+2) and the point (-2, 5/2) are also shown, for reference. (The slope of the curve at x=-1 is -2, and the normal to the curve at that point has slope 1/2. The normal goes through the point (-2, 5/2), consistent with f(x) being a minimum at x=-1.)

Paige ran four miles a day last week. This week, she ran five miles a day. How did adding a mile most likely affect her workout?
Answer:
A. It increased both her intensity and her workout time.
Step-by-step explanation:
A. It increased both her intensity and her workout time.
B. It decreased her intensity but increased her workout time.
C. It increased her intensity but decreased her workout time.
D. It decreased both her intensity and work out time
Last week = 4 miles per day
This week = 5 miles per day
Intensity refers to how hard one exercises.
Workout time refers to how long one exercises the body.
By adding a mile, she has increased how hard she exercises her body (intensity))
And also increased how long she exercises the body (workout time) because the time she spent on 5 miles per day is more than time spent on 4 miles per day

The diameter of his friend's similar wand is 4.5 millimeters shorter than the diameter of Arun's wand. How much wire did his friend need to make the circular part of his wand? Use 3.14 for T. Round to the nearest hundredth.
Answer:
15.9 mm²
Step-by-step explanation:
We solve using Area of the circle formula
Area of a circle = πr²
Diameter of his friend's wand = 4.5mm
Radius = 4.5mm/2
= 2.25 mm
How much wire did his friend need to make the circular part of his wand? Use 3.14 for π
= 3.14 × (2.25mm)²
= 15.89625 mm²
Approximately = 15.9 mm²
solve for the unknown value
Answer:
77
Step-by-step explanation:
180-61-42
Answer:
x = 77°
Step-by-step explanation:
the total among these angles are 180° so add 61 + 42 which equals 103 then subtract it from the total
180° - 103° = 77°
x = 77°

Roll one fair, six-sided die, numbered 1 through 6. Let A be the event you will roll an even number.
Answer:
P(A) = 1/2
Step-by-step explanation:
The question seems incomplete, I assume that we want to find the probability of event A.
Here we have a fair six-sided dice, so each one of the six numbers has exactly the same probability of being rolled.
Such that the possible outcomes of rolling the dice is:
{1, 2, 3, 4, 5, 6}
Now we define event A as rolling an even number.
The possible outcomes such that the event A is true are the even numbers:
{2, 4, 6}
So we have 3 outcomes out of 6.
Then the probability of rolling an even numbers, is just the quotient between the number of outcomes of even numbers (3) and the total number of outcomes (6).
Then:
P(A) = 3/6 = 1/2 = 0.5
