Find the 8th term of the arithmetic sequence - 2x + 7,4x + 1, 10x – 5, ...
Answer:
Step-by-step explanation:
a1 = -2x + 7
d = 4x + 1 - (-2x + 7)
d = 4x + 1 + 2x - 7
d = 6x - 6
n = 8
a8 = -2x + 7 + (n-1)*d
a8 = -2x + 7 + (8 -1 ) * (6x - 6)
a8 = -2x + 7 + 7 * (6x - 6)
a8 = -2x + 7 + 42x - 42
a8 = 40x - 35

I need help on this question
Answer:
I think you need to combine the equations, which would end with 26x - 2, and to solve for x just isolate it by adding to the other side which would look like 26x = 2
Then divide 26 on both sides, 26x/26 = 2/26
You should end with x = 1/13

Answer:

Step-by-step explanation:
Just find the area of all the triangles and add
Answer:
18 metres squared
Step-by-step explanation:
it looks like you want to find the area of the kite as a whole, and lucky for you, the kite is conveniently cut into right triangles.
to find the area of a right triangle, you use the equation
A = (b × h)/2
where A is the area, b is the base, and h is the height.
now we plug in the numbers for each individual area and solve for the total area.
let's start with the 1st triangle, where it's base is 30cm and the height is 25 cm.
A = (30 × 25)/2
A = 375 cm squared
now the next one whose base is 30 and it's height is also 25 (We just did this last time so the area is the same)
A = 375 cm squared
now we'll do the next one whose base is 30 and height is 35.
A = (30 × 35)/2
A = 525 cm squared
and the last one is the same as the one we just did so I'll just copy the other answer.
A = 525 cm squared
alright now we'll add up all of the areas we just found to get the total area of the kite.
Total A = 375 + 375 + 525 + 525
Total A = 1800 cm squared
now we will divide our total by 100 because it takes 100 centimetres to get 1 metre and what we have right now is centimetres.
1800/100 = 18 metres squared.

=648 in.^2
Answer:
648 inches
Step-by-step explanation:
First, you do 14 times 12 times 2 and get 336.
Next, you do 14 times 6 times 2 and get 168.
Then you do 6 times 12 times 2 and get 144.
Now add 336, 168, and 144 together to get 648.
Which of these quadrilaterals can have two sides with length 8 cm and two sides with length 3 cm? Select all that apply. Rectangle Rhombus Square Parallelogram Trapezoid
Answer: Rectangle
Rhombus
Parallelogram
Step-by-step explanation:
A rectangle has four sides and the opposite sides are equal.
A rhombus is simply a flat shape that has 4 equal straight sides and the sides have equal length.
A square has all the four sides equal.
A parallelogram is a quadrilateral that has two pairs of parallel sides. It should be noted that the opposite sides of the parallelogram have equal length.
A trapezoid doesn't have two sides with equal lengths. Therefore, the correct answer to the question will be:
• Rectangle
• Rhombus
• Parallelogram

A new LED light bulb uses 10 watts of power. Since
energy
=
power
×
time
, then the energy used for this light bulb can be found my multiplying the power times the time the bulb is lit. If the bulb is lit for one hour, the energy used will be 10 watt*hours or 10 Wh. If three 10 watt bulbs in one room are kept on for 5 hours, how many watt*hours of energy are used?
Parents sometimes yell at their children for leaving the light on in their bedroom when they aren't in the room. If the child's room is lit with two 10 watt bulbs for one extra hour a day for everyday of the year (365), and the cost of energy is $0.068 per kilowatt*hour (kWh), how much money is wasted on lighting that isn't being used, to the nearest cent.
Answer:
150 Wh
I guess the question means, how much money is wasted on lighting in a year ?
$0.50
Step-by-step explanation:
3 × 10W × 5 hours = 150 Wh
2 × 10W × 1 hour × 365 × 0.068 / 1000
divided by 1000, because the price is in kWh (1000 Wh), but the rest of the calculation refers to W. so, we need to bring all factors to the same dimension. the division by 1000 either brings the Wh to kWh, or the price to the price for Wh (instead of kWh). it does not matter which one. just one of these 2 things have to happen here, so that all factors have the same dimension.
=> 20 × 365 × 0.068 / 1000 = 7300 × 0.068 / 1000 =
= 7.3 × 0.068 = $0.50 (rounded from 0.4964)
On a test that has a normal distribution, a score of 49 falls three standard deviations below the mean, and a score of 59 falls two standard deviations above the mean. Determine the mean of this test.
The mean of the test that has a normal distribution is 55.
What is the mean of the test?Let's denote the mean of the test by μ, and the standard deviation by σ. We can use the information given to set up a system of two equations:
49 = μ - 3σ equation (1)
59 = μ + 2σ equation (2)
To solve for μ, we can eliminate σ by adding equations (1) and equation (2) to get:
49 + 59 = μ - 3σ + μ + 2σ
Simplifying, we get:
108 = 2μ - σ
We can also solve for σ by subtracting equation (1) from equation (2) to get:
59 - 49 = μ + 2σ - (μ - 3σ)
Simplifying, we get:
10 = 5σ
Therefore, σ = 2.
Substituting this value of σ into the equation we found earlier, we get:
108 = 2μ - σ
108 = 2μ - 2
Solving for μ, we get:
2μ = 108 + 2
2μ = 110
μ = 110/2
μ = 55
Therefore, the mean of the test is 55.
