Telephone poles are stored in a pile with 30 poles in the first layer, 29 in the second, and so on. If there are 12 layers, how many telephone poles does the pile contain?
Answer: 294
Step-by-step explanation:
Given
First layer has 30 Poles
Second layer has 29 Poles
There are twelve layers
It follows an A.P. with first term [tex]a_1=30[/tex] and common difference [tex]d=-1[/tex]
Sum of n terms of an A.P. is
[tex]\Rightarrow S_n=\dfrac{n}{2}[2a+(n-1)d][/tex]
Insert the values
[tex]\Rightarrow S_n=\dfrac{12}{2}[2\times 30+(12-1)(-1)]\\\\\Rightarrow S_n=6[60-11]\\\Rightarrow S_n=294[/tex]
So, there are 294 Poles in 12 layers
1;3;5;7…(determine the value of the 19th term of the sequence)
Answer:
37
Step-by-step explanation:
fistly find how much different
3-1=2 5-3=2 7-5=2
so for the next and next value just plus two until the 19th then you will get 37
=============================================================
Explanation:
a = 1 is the first term
d = 2 is the common difference, since we add 2 to each term to get the next term.
The nth term is a+d(n-1) which becomes 1+2(n-1). That simplifies to 2n-1
The last step is to plug in n = 19 and you should get 2(19)-1 = 37

1/2n+3=6 what is the solution to this equation
Answer:
n=6
Step-by-step explanation:
1/2 n + 3 = 6
Subtract 3 from each side
1/2 n +3-3=6-3
1/2n = 3
Multiply each side by 2
1/2 n * 2 = 3*2
n = 6
Given that,
1/2n + 3 = 6
Now we can subtract 3 from each side,
→ 1/2 n +3-3 = 6-3
→ 1/2n = 3
Now we can multiply each side by 2,
→ 1/2 n × 2 = 3 × 2
→ n = 6
Hence, 6 is the correct answer.
What is the slope of a line perpendicular to the line whose equation is x + 2y = 2. Fully simplify your answer.
9514 1404 393
Answer:
2
Step-by-step explanation:
We can solve for y to find the slope of the given line.
x +2y = 2
2y = -x +2 . . . . . subtract x
y = -1/2x +1 . . . . divide by the coefficient of y
The slope is the x-coefficient, -1/2.
Any perpendicular line will have a slope that is the opposite reciprocal of this:
-1/(-1/2) = 2
A perpendicular line will have a slope of 2.

June has 248 oranges. She sells of these oranges. How many oranges did June sell?
Answer.
Answer:
93. Divide 248 by 8. One eighth of 248 = 31.
June sold 3/8 of the 248 oranges.
If 1/8 = 31 and June sold 3/8 of the oranges.
Multiply 3 × 31. Therefore June sold 93 oranges.

It is one-half the area of a square of side length 4 units.
It is twice the area of a rectangle of length 4 units and width 2 units.
It is twice the area of a square of side length 4 units.
9514 1404 393
Answer:
(b) It is one-half the area of a square of side length 4 units.
Step-by-step explanation:
The triangle described can be formed by drawing the diagonal through a square 4 units on a side. Such a diagonal cuts the square cleanly in half, so the area of the triangle is half the area of the square.

If the measure of angle 2 Is (4x+10)degrees and the measure of angle 3 is (3x-5)degrees, what is the measure of angle 2 in degrees?
Answer:
110°
Step-by-step explanation:
4x+10 + (3x-5) = 180
7x + 5 = 180
7x = 175
x = 25
∠2 = 4(25) + 10 = 110
The measure of angle 2 in degrees, when both lines are perpendicular, is approximately 58.56 degrees.
To find the measure of angle 2 when the lines are perpendicular, we can set up an equation. Since the angles are formed by perpendicular lines, we know that the sum of angle 2 and angle 3 will be equal to 90 degrees. Mathematically, we can write this as:
(4x + 10) + (3x - 5) = 90
Now, let's solve the equation to find the value of x. First, combine like terms:
4x + 3x + 10 - 5 = 90
7x + 5 = 90
Next, isolate x by subtracting 5 from both sides:
7x = 85
Finally, divide by 7 to solve for x:
x = 85 / 7 ≈ 12.14
Now that we have the value of x, we can find the measure of angle 2 by substituting x back into its expression:
Angle 2 = 4x + 10
Angle 2 = 4(12.14) + 10
Angle 2 ≈ 48.56 + 10
Angle 2 ≈ 58.56 degrees

can someone help me solve this pls ? solve |x| + 7 < 4
Answer:
no solution
Step-by-step explanation:
|x| + 7 < 4
Subtract 7 from each side
|x| + 7-7 < 4-7
|x| < -3
But an absolute value must be greater than or equal to zero
There is no solution
Answer: No solutions
Let's solve the inequality step-by-step
[tex]|x|+7<4[/tex]
First subtract 7 from both sides
[tex]|x|+7-7<4-7\\|x|<-3[/tex]
Now usually you'd solve absolute value, but absolute value cannot be less than 0 so there can't be a solution.

Answer:
C = 2(3.14)r
C = (3.14)d

Circumference in terms of radius:

So replacing pi with 3.14 you would get 2(3.14)r
Circumference in terms of diameter:

The area of a triangle is 2/5 square feet. What is the base of the triangle if the height is 6/5 feet?
24/25 feet
25/24 feet
2/3 feet
3/2 feet
Answer:
2/3 feet.
Step-by-step explanation:
The formula for finding the area of a triangle is A = (B x H)/2. Or, area is equal to base times height, all divided by two. In your case, we don't know the base. If we substitute in values, we get 2/5 = (B x 6/5)/2.
Next, we have to multiply both sides by two, to cancel the "/2." That results in 4/5 = B x 6/5. Then, to isolate the variable, we have to divide both sides by 6/5. 4/5 ÷ 6/5 is 4/5 x 5/6. The fives cancel out, and we are left with 4/6.
Finally, we simplify! 4/6 simplifies to 2/3.

3x+7y=1 and y=x-7
Substitute the second equation in for y in the first equation
3x+7( x-7)=1

Combine like terms
10x - 49 =1
Add 49 to each side
10x-49+49 = 1+49
10x = 50
Divide by 10
10x/10 = 50/10
x = 5

"The sine of any acute angle is equal to the cosine of its complementary angle."[help me plzz!!]
==================================
Work Shown:
sin(angle) = opposite/hypotenuse
sin(alpha) = MN/NP
sin(alpha) = y/z
---------
cos(angle) = adjacent/hypotenuse
cos(beta) = MN/NP
cos(beta) = y/z
----------
Both sin(alpha) and cos(beta) are equal to y/z, so that means sin(alpha) = cos(beta). This is true because alpha+beta = 90, ie the angles are complementary.
Similarly, you should find that sin(beta) and cos(alpha) are both equal to x/z, which is further proof that the statement is true.
