The 100th term of the sequence is 2130.
How to calculate the value?a3 = a + 2d = 93
a5 = a + 4d = 135
Compute both equations
(4d - 2d) = (135 - 93)
2d = 42
d = 42/2 = 21
a + 2d = 93
a + 2(21) = 93
a + 42 = 93
a = 94 - 42 = 51
100th term will be:
= a + 99d
= 51 + 99(21)
= 51 + 2079
= 2130

What is the scale factor from the drawing to the actual airplane
the scale factor is _
Answer: 2
Step-by-step explanation: I just did this lesson
A scale factor is a ratio between the scale of the original object in an actual sense and the prototype figure of the same object.
If the height of the actual airplane is 20m and the in the scale drawing the height is 10m.
The scale factor of the airplane is 200.
What is a scale factor?A scale factor is a ratio between the scale of the original object in an actual sense and the prototype figure of the same object.
We have
The height of the plane in scale drawing:
= 10 cm
The height of the plane in an actual airplane.
= 20 m
The scale factor of the height of the airplane:
= 20m / 10 cm
[ 1 m = 100 cm ]
= (20 x 100) cm / 10 cm
= 200
Thus,
The scale factor of the airplane is 200.

Joel is buying packs of baseball cards to add to his collection. He wants to have at least 65 total. He already has 15 and each pack has 5 cards, c, in it. How many packs will Joel need to buy in order to have at least 65 total cards?
Answer:
10 cards
Step-by-step explanation:
In order to find how many packs Joel needs to buy we need Make an equation
Equation = 5c + 15 = 65
where,
c = cards5c+15=65
Step 1: Subtract 15 from both sides.
5c+15−15=65−15
5c=50
Step 2: Divide both sides by 5.
5c/5 = 50/5
c=10
Therefore, Joel need to buy total of 10 cards in order to have at least 65 total cards
[tex] {x}^{2} + 70 = 17x[/tex]
solve
I really neeed this done asap
Answer: x=7 x=10
Step-by-step explanation:
[tex]x^2+70=17x\\x^2+70-17x=17x-17x\\x^2-17x+70=0\\x^2-7x-10x+70=0\\x(x-7)-10(x-7)=\\(x-7)(x-10)=0\\x-7=0\\x=7\\x-10=0\\x=10[/tex]
Answer:
x = 7, x = 10
Step-by-step explanation:
x² + 70 = 17x ( subtract 17x from both sides )
x² - 17x + 70 = 0 ← in standard form
consider the factors of the constant term (+ 70) which sum to give the coefficient of the x- term (- 17)
the factors are - 10 and - 7 , since
- 10 × - 7 = + 70 and - 10 - 7 = - 17 , then
(x - 10)(x - 7) = 0 ← in factored form
equate each factor to zero and solve for x
x - 7 = 0 ⇒ x = 7
x - 10 = 0 ⇒ x = 10
If m∠j=91 m∠l=16 and m∠k=73 list the sides of ∆JLK in order from smallest to largest
Answer:
ikj
Step-by-step explanation:
In a triangle:
The shortest side is opposite the smallest angle.The longest side is opposite the biggest angle.When labeling angles and sides of triangles, it is convention to label the side opposite an angle with the same letter but in lower case.
Therefore in ∆JLK:
Side j is opposite angle J.Side l is opposite angle L.Side k is opposite angle K.As 16 < 73 < 91
⇒ m∠I < m∠K < m∠J
As the angles of ∆JLK in order from smallest to largest are IKJ, then the sides of ∆JLK in order from smallest to largest are ikj.

Answer:
See answers below
Step-by-step explanation:
This type o problem is known as a Diamond problem
From the diamonds on the top row, it is clear that the top cell of the diamond is the product of the two side numbers and the bottom is the sum of these numbers.
I will use top for the top cell and bottom for the bottom cell, left for and right respectively for left and right cells
a. Top = 2 x 5 = 10; Bottom = 2 + 5 = 7
b. Top = -2 x -1 = 2; Bottom = -2 - 1 = -3
c. Top = Left x Right = 8
Bottom = Left + Right = 6. The only two numbers that satisfy this equation are Left = 4 and Right = 2 since 4 x 2 = 8 and
4 +2 = 6
Answer to c: Left = 4, Right = 2
d We have Let unknown left be L and unknown bottom be B
We have L x (1/2) = 4 for the product
[tex]\rm{\frac{L}{2} = 4}\\\\L = 2 x 4 = 8[/tex]
We have Bottom = Left + Right = 8 + 1/2 = [tex]8\frac{1}{2}[/tex] = 17/2
Answer to d. : Left = 8, Bottom = 17/2
e. Similar to c.
Top = Left x Right = 12;
Bottom = Left + Right = -7
12 can be 2 x 6 or 3 x 4 (same as 4 x 3) or 12 x 1. 4 and 3 are the obvious choices and since they add up to - 7 they both have to be negative
So Left = -3, Right = -4
Note: (-3) x (-4) results in +12

We are given the equations:
7 x - y = 7 … (1)
x + 2 y = 6
x = 6 - 2 y … (2)
Substitute equation (2) in equation (1), we get that:

Inequality 1: g > 80
Inequality 2: g ≤ 3k – 3
Which inequality did Jane write incorrectly, and how could it be corrected?
Inequality 1 is incorrect; it should be g ≤ 80.
Inequality 1 is incorrect; it should be g ≥ 80.
Inequality 2 is incorrect; it should be g < 3k – 3.
Inequality 2 is incorrect; it should be g ≥ 3k – 3.
Answer:

Answer:

Step-by-step explanation:
First start by raising all the numbers to the power indicated:
5^4 = 625
8^5 = 32768
2^9 = 512
5^2 = 25
Then divide the numerators by the denominators:
625 / 8 = 78.125
32768 / 64 = 512
512 / 25 = 20.48
Finally, multiply all the numbers together
78.125 * 512 * 20.48 = 819200
4x = 0.5(2x- 12) solve for x
Answer: x = -2
Step-by-step explanation:
4x=0.5(2x−12)
Use the distributive property to multiply 0.5 by 2x−12.
4x=x−6
Subtract x from both sides.
4x−x=−6
Combine 4x and −x to get 3x.
3x=−6
Divide both sides by 3.
x= 3−6
Divide −6 by 3 to get -2.

- The circles are identical. Find the circumference of each circle. Round your
answer to the nearest tenth.
4x
6x - 6
Answer:
Circumference = 75.4
Step-by-step explanation:
Since the circles are identical, that means that the radii must be equal.
4x=3x+3
x=3
That means that radius = 12
The formula for the circumference = 2pi × radius
2pi × 12 = 24pi ≈ 75.4
Answer:
75.4 (nearest tenth)
Step-by-step explanation:
The diameter of a circle is the distance from one side of the circle to the other through the center. The diameter is the widest part of the circle.
The radius of a circle is the distance from the center to the circumference. The radius is half the diameter of a circle.
We have been given the radius of the circle on the left: r = 4x.
Therefore, as the diameter is twice the radius, the diameter of the circle on the left is: d = 2(4x) = 8x
We have been given the diameter of the circle on the right: d = 6x + 6
Equate the two diameters and solve for x:
⇒ 8x = 6x + 6
⇒ 8x - 6x = 6x + 6 - 6x
⇒ 2x = 6
⇒ 2x ÷ 2 = 6 ÷ 2
⇒ x = 3
Substitute the found value of x into one of the diameter expressions to find the diameter of both circles:
⇒ d = 8x
⇒ d = 8(3)
⇒ d = 24
Circumference of a circle
C = πd
(where d is the diameter)
Substitute the found diameter into the circumference formula:
⇒ C = πd
⇒ C = 24π
⇒ C = 75.39822...
⇒ C = 75.4 (nearest tenth)
Therefore, the circumference of each circle is 75.4 units (nearest tenth).
