What is 82+(12 3+4)-10
Answer:
82 + (12 + 3 + 4) -10 = 91
82 + (12 times 3 + 4) -10 = 156
82 + (12 divided by 3 + 4) -10 = 73.71
82 + (12 - (3+4)) -10 = 77
I wasn't sure what the space between the 12 and the 3 + 4 meant so I put the answers to what it could have possibly meant.
Determine the common difference, the fifth term, the nth term, and the 100th term of the arithmetic sequence. 2, 7, 12, 17,...d= ________a5= _______an=_______
The common difference of the arithmetic sequence 2, 7, 12, 17, ... is 5. The fifth term is 22. The nth term is given by the formula an = 2 + 4(n - 1). The 100th term is 497.
The common difference is calculated by subtracting the first term from the second term. In this case, 7 - 2 = 5. The fifth term is calculated by using the formula an = a1 + (n - 1)d, where a1 is the first term, n is the term number, and d is the common difference. In this case, a5 = 2 + (5 - 1)5 = 22. The nth term is also calculated using the same formula. In this case, an = 2 + 4(n - 1). The 100th term is calculated by plugging in n = 100 into the formula, which gives an = 497.

The difference of the same side interior angles of two parrelels lines is 50 degrees find all angles
Answer:
Angle 1 = 115 degrees
Angle 2 = 65 degrees
Step-by-step explanation:
Angle 1: Same-side interior angle of Line 1
Angle 2: Same-side interior angle of Line 2
We know that the difference between the angles is 50 degrees. Since the angles are supplementary, we can write the equation:
Angle 1 + Angle 2 = 180
Now, we need to express the difference between the angles in terms of Angle 1 or Angle 2. We can choose either angle, so let's express it in terms of Angle 1:
Angle 1 - Angle 2 = 50
We can rewrite this equation as:
Angle 1 = 50 + Angle 2
Now substitute this expression for Angle 1 into the first equation:
(50 + Angle 2) + Angle 2 = 180
Combine like terms:
2Angle 2 + 50 = 180
Subtract 50 from both sides:
2Angle 2 = 130
Divide by 2:
Angle 2 = 65
Now substitute this value back into the equation for Angle 1:
Angle 1 = 50 + Angle 2
Angle 1 = 50 + 65
Angle 1 = 115
Therefore, the angles are as follows:
Angle 1 = 115 degrees
Angle 2 = 65 degrees
Matt earns $6 per hour spreading mulch and $4 per hour pulling weeds last week mat spent 3 hours spreading mulch and 2 hours pulling weed how many money did Matt earn?
From the word problem, we know that:
• Matt earns $6 per hour spreading mulch
,• Matt earns $4 per hour pulling weeds
Since Matt spent 3 hours spreading mulch, we can find his earnings multiplying 3 by $6.
\(3\cdot\text{\$}6=\text{\$}18\)Since Matt spent 2 hours pulling a weed, we can find his earnings multiplying 2 by $4.
\(2\cdot\text{\$}4=\text{\$}8\)Finally, we add up Matt's earnings from doing both activities.
\(\text{\$}18+\text{\$}8=\text{\$}26\)Therefore, last week Matt earned $26.

ASAP PLEASEE The relationship between the number of pies-to-cakes chosen by middle school students as their favorite dessert is shown in the table.
Pie 36 42 60
Cake D 7 B
Total C A 70
What is the value of C in the table?
6
10
42
49
Step-by-step explanation:
To find the value of C, we need to add the values in the row labeled "Total."
Adding the values in the "Total" row, we get:
36 + 42 + 60 = 138
D + 7 + B = C
A + 70 = C
We can rewrite the last equation as:
C = A + 70
Substituting the values of A and C in the second equation, we get:
D + 7 + B = A + 70
Simplifying, we get:
D + B = A + 63
We have three equations and three unknowns (D, B, and C). We can use substitution to solve for C.
Substituting the value of A + 70 for C in the equation above, we get:
D + B = C - 7
Substituting the value of C - 7 for A + 63, we get:
D + B = (C - 7) - 6
Simplifying, we get:
D + B = C - 13
Substituting the values of D and B from the table, we get:
C = 42 + 7 = 49
Therefore, the value of C in the table is 49.
Answer: The value of C in the table is 42.
Step-by-step explanation:
To find the value of C, we need to add the values in the first row of the "Total" column.
36 + 42 + 60 = 138
Then we look at the "Pie" column and add up the values for D, A, and B.
D + A + B = 36 + 42 + 60 = 138
Since the totals for the "Pie" column and the "Total" column are the same, we know that the value of C is the same as the value of A, which is 42.
Therefore, the value of C in the table is 42.

A rectangular window is topped with a semicircle. The height of the rectangular part is 1 more than 3 times its width, w meters. Which function represents the total area, A, of the window in terms of the width?
The total surface area of the window is w + 3\(w^{2}\) +\(\pi\)\(w^{2}\)/8
What is a semi-circle?A semi-circle is a part of a full circle cut into two equal part.
The base of the semicircle is taken to be the diameter of the circle because it was cut through its diameter.
width of the rectangle = w
Since the height of the rectangular part is 1 more than 3 times the width.
height = 1 + 3w
The diameter of the semi-circle is the width of the rectangle = W
So, its radius is = w/2
Area of the rectangle = height x width = (1 + 3w) x w
= w + 3\(w^{2}\)
Area of the semi-circle = \(\pi\)\(r^{2}\)/2
But r = w/2
Therefore,
Area of semi-circle = \(\pi\)\((w/2)^{2}\)/2
= \(\pi\)\(w^{2}\)/8
Total surface area of the rectangular window = area of semicircle + area of rectangle
= (w + 3w + \(\pi\)\(w^{2}\)/8) m

Let A represent the height of Snowman A t hours after sunrise and let B represent the height of Snowman B t hours after sunrise. Write an equation for each situation, in terms of t, and determine which Snowman is taller after 9 hours.
After 9 hours, Snowman A is 9 inches tall, and Snowman B is 7 inches tall. Therefore, Snowman A is taller than Snowman B after 9 hours.
Snowman A has an initial height of 36 inches and melts at a rate of 3 inches per hour.
We can write its equation as:
A(t) = 36 - 3t, where A(t) represents the height of Snowman A at time t hours after sunrise.
Snowman B has an initial height of 52 inches and melts at a rate of 5 inches per hour.
Its equation can be written as:
B(t) = 52 - 5t, where B(t) represents the height of Snowman B at time t hours after sunrise.
Now, we need to determine which snowman is taller after 9 hours. We will do this by plugging t = 9 into both equations:
A(9) = 36 - 3(9) = 36 - 27 = 9 inches
B(9) = 52 - 5(9) = 52 - 45 = 7 inches
After 9 hours, Snowman A is 9 inches tall, and Snowman B is 7 inches tall. Therefore, Snowman A is taller than Snowman B after 9 hours.

Use double integrals to find the area of the region bounded by the parabola y=2-x^2, and the lines x-y=0, 2x y=0.
The area of the region bounded by the parabola y=2-x^2, and the lines x-y=0 and 2x-y=0 is 2.667 square units.
To find the area, we set up a double integral over the given region. The region is bounded by the curves y=2-x^2, x-y=0, and 2x-y=0. We need to determine the limits of integration for x and y. The parabola intersects the x-axis at x=-2 and x=2.
The line x-y=0 intersects the parabola at x=-1 and x=1. The line 2x-y=0 intersects the parabola at x=-√2 and x=√2. Therefore, the limits for x are -√2 to √2, and the limits for y are x-y to 2-x^2. Integrating the constant 1 over these limits, we obtain the area as approximately 2.667 square units.
