Answer:
$109.97
Step-by-step explanation:
Each straight piece of wire is the diagonal of a square that is 3" on a side. The Pythagorean theorem tells you the length of that diagonal is ...
d = √(3^2 +3^2) = √18 = 3√2 . . . inches
There are 4 such diagonals on each trivet, so the total length of wire for 12 trivets is ...
(12)(4)(3√2) = 144√2 . . . inches
At a cost of $0.54 per inch, the total cost for 12 trivets will be ...
($0.54)(144√2) = $109.97
The cost of the copper wire for making 12 trivets is $109.97.

Answer:
3.99 or 4
Step-by-step explanation:
The sum of the six known measurements is 78.4
3.99+78.4=82.39
Divide 82.39 by seven to get the average and it equals 11.77

Two brothers went shopping at a back-to-school sale where all shirts were the same price, and all the shorts too. The younger brother spent $230 on 8 new shirts and 10 pairs of shorts. The older brother purchased 8 new shirts and 4 pairs of shorts and paid a total of $116. How much did each item cost?
Answer:
Younger: 12.78 per item
Older: 9.67 per item
Step-by-step explanation:
Well, if all the shirts and shorts were the same price divide the total price and total amount of items they bought.
Younger Brother:
8 shirts + 10 shorts = 18 items for $230
$230 ÷ 18 items = about 12.78 per item (it comes out to a lot of number so I estimated it the nearest hundredth)
Older Brother:
8 shirts + 4 shorts = 12 items
$116 ÷ 12 items = about 9.67 per item (estimated again)
Determine which of the lines, if any, are parallel. Explain.
Line a passes through (-1, - 2) and (1,0).
Line b passes through (4, 2) and (2, – 2).
Line c passes through (0, 2) and (-1,1).
The slopes are
Answer:
Line A and Line C are parallel
Step-by-step explanation:
Slope Equation: [tex]m=\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]
Step 1: Find the slope of the first line
Line a passes through (-1, -2) and (1, 0).
[tex]m = \frac{(0- (-2))}{(1 - (-1))}[/tex]
[tex]m=\frac{2}{2}[/tex]
[tex]m=1[/tex]
Step 2: Find the slope of the second line
Line b passes through (4, 2) and (2, -2).
[tex]m = \frac{(-2- 2)}{(2 - 4)}[/tex]
[tex]m = \frac{-4}{-2}[/tex]
[tex]m=2[/tex]
Step 3: Find the slope of the third line.
Line c passes through (0, 2) and (-1, 1).
[tex]m=\frac{(1-2)}{(-1 - 0)}[/tex]
[tex]m=\frac{-1}{-1}[/tex]
[tex]m=1[/tex]
Answer: Line A and Line C are parallel

Answer:
answer is:
Circum: 25.13274 cm^2
Area: 50.26548 cm^2
Step-by-step explanation for the CIRCUMFERNCE ONLY:
Original equation for the circumference of a circle:
C=2(pi)r
We will use 3.14 as pi
We know that the diameter of a circle is 2 times the radius, so in order to find the radius all we have to do is divide the diameter by 2.
8/2 = 4
So now we know what the radius is equal to.
4
So now just plug in your numbers to the original equation
2 X (3.14) X 4
25.13274
If we were to round up the answer would be
25.13

For f(x)=0.01(2) , find the average rate of change from x=3 to x=8.
Option b. 0.496
Step-by-step explanation:we know that
f(x)=0.01(2^{x})
The average rate of change is equal to
\frac{f(b)-f(a)}{b-a}
where
a=3
b=8
f(a)=f(3)=0.01(2^{3})=0.08
f(b)=f(8)=0.01(2^{8})=2.56
Substitute
\frac{2.56-0.08}{8-3}
\frac{2.48}{5}
0.496
Enter an expression equivalent to (3x^2+2y^2-3x)+(2x^2+y^2-2x)-(x^2+3y^2+x) using the fewest number of possible terms
Answer:
2x(2x - 3)
Step-by-step explanation:
Given:
(3x^2+2y^2-3x)+(2x^2+y^2-2x)-(x^2+3y^2+x)
Written as:
(3x² + 2y² - 3x) + (2x² + y² - 2x) - (x² + 3y² + x)
= 3x² + 2y² - 3x + 2x² + y² - 2x - x² - 3y² - x
Collect like terms
= 3x² + 2x² - x² + 2y² + y²- 3y² - 3x - 2x - x
= 4x² + 0 - 6x
= 4x² - 6x
= 2x(2x - 3)

Answer:
∠D = 68°
Step-by-step explanation:
In a quadrilateral that is inscribed in a circle, opposite angles are supplementary.
∠D = 180° - ∠B
∠D = 180° -112°
∠D = 68°

Final Step: Biggest Common Factor Number
We found the factors and prime factorization of 36 and 56. The biggest common factor number is the GCF number.
So the greatest common factor 36 and 56 is 4.
The highest common factor of 36 and 56 is 4 after using division algorithm, the answer is 4.
What is LCM?It is defined as the common number of two integers, which is the lowest number that is a multiple of two or more numbers. The full name of LCM is the least common multiple.
It is given that:
The two numbers are: 36 and 56
As we know GCF means highest common factor, the factor which presents the in both numbers:
The GCF(36, 56) can be found using the Division Lemma:
56 = 36x1 + 20
36 = 20x1 + 16
20 = 16x1 + 4
16 = 4x4 + 0
The value of GCF(36, 56) :
GCF(36, 56) = 4
Thus, the highest common factor of 36 and 56 is 4 after using division algorithm, the answer is 4.

Answer:
A. The perimeter of the third triangle will be equal to the perimeter of the second triangle because the lengths of line segments are preserved during translations.
Step-by-step explanation:
When a shape is translated, it simply means it is moved. Nothing about it is being changed besides the location. Therefore, it will have the same perimeter because its sides are the exact same.

Find the value of x. If necessary, write your answer in simplest radical form. 30 x 25 x nothing (Simplify your answer. Type an exact answer, using radicals as needed.)
Answer:
x = 38.05
Step-by-step explanation:
Using the Pythagoras theorem to find x
x is the hypotenuse
The other sides are opposite and adjacent
x² = 30²+25²
x² = 900+625
x² = 1525
x = √1525
x = 39.05

Answer:
B. 160 inches
Step-by-step explanation:
The wrapping paper would be the surface area of the box.
The surface area of a box is 2(h * W) + 2(h * L) + 2(W * L)
h = height
W = width
L = length
length x width x height
length = 5 in
width = 2 in
height = 10 in
2(10 * 2) + 2(10 * 5) + 2(2 * 5)
2(20) + 2(50) + 2(10)
40 + 100 + 20
160 inches
How many right angles need to be put together to make:
a.) 360 degrees?
b.) 180 degrees?
C.) 270 degrees?
d.) A straight angle?
Answer:
A 180° angle is called a straight angle. Angles such as 270 degrees which are more than 180 but less than 360 degrees are called reflex angles. A 360° angle is called a complete angle.
Answer:
A. 4
B. 2
C. 3
D. 2
Step-by-step explanation:
Multiplication!!! Always remember that a right angle is 90 degrees, also a straight angle is 180 degrees..
Remember like this:
90 x 1 =90
90 x 2 =180
90 x 3 = 270
90 x 4 = 360
