Answer:
a₁₅ = 240 55 is not term in the sequenceStep-by-step explanation:
[tex]n(n+1)=240\\\\n^2+n-240=0\\\\n=\dfrac{-1\pm\sqrt{1-4(-240)}}{2}=\dfrac{-1\pm\sqrt{1+960}}{2}=\dfrac{-1\pm31}{2}\quad\wedge\quad n\in N_+\\\\n=15[/tex]
if n is even number then (n+1) is odd number and if n is odd number then (n+1) is even number
The product of numbers where one of them is even will always be even.
55 is odd number so it is not term of this sequence.
Find the value of the missing angle
Answer:
130 degrees.... I am pretty sure
Cus angles of a triangle add to 180 and so the inside angle is 130 and they are vertical angles so they are the same right? right?
Step-by-step explanation:
Answer:
130 degrees
Step-by-step explanation:
I first came up with the equation 30+20+?=180 (I got 180 because every angle in a triangle added up is 180), then added the 30 and 20 to get 50+?=180. I subtracted 50 from both sides and got ?=130. I know that the angle on the inside and the outside are equal because it seems like a reflection, so if the inside angle is 130 the outside angle is 130 degrees too.
Hope this helps you :)
jamie and rhyns share some money in the ratio of 2:3.jamie gets 40 pounds. how much does rhys get.
Answer:
60 pounds
Step-by-step explanation:
The ratio of Jamie to Rhys is 2 to 3.
Jamie gets 40 pounds.
40 pounds is 20 times 2, so Rhys also has to get 20 times the amount in the ratio.
20 * 3 = 60
Answer: 60 pounds
4. Find the slope of the line through the
points A(8,7) and B(5,-2).
Explanation:
Answer:
Slope equals to 3
Step-by-step explanation:
-2-7=-9 over 5-8=-3. You then divide the 9 by 3 and because they are both negative they equal a positive.

the speed of a computer depends on the amount of memory.
Answer:
i believe the answer is...C
Step-by-step explanation:speed(memory) or s(m)
Step-by-step explanation:
Dependent variable states that a variable whose value dependent upon the dependent variable.
For example:
x is the independent variable and f(x) is the dependent variable
Given the statement:
The speed of a computer depends on the amount of memory.
Let m represents the amount of memory and s represents the speed of a computer.
m = Independent variable
s(m) = Dependent variable on m
Then
Answer:speed (memory), or s(m)

Mr Roman drove from his hometown to another city. He used 12 1/4 gallons of gas for 318 1/2 mile trip. On average, how many miles did Mr. Roman travel per gallon of gas
Answer: 26 miles
Step-by-step explanation:
Gallons of gas used = 12 1/4 = 12.25
Distance of the trip = 318 1/2 = 318.5 miles
The miles that Mr. Roman travel per gallon of gas will be:
= Distance of the trip / Gallons of gas used
= 318.5/12.25
= 26 miles
Mr Roman travelled 26 miles per gallon of gas

X= (a+b+c)/(ab)
for a.
Answer:
a = (b + c)/(bx - 1)Step-by-step explanation:
Given
x= (a+b+c)/(ab)Solving for a
x = (a + b+ c)/(ab)abx = a + b+ cabx - a = b + ca(bx - 1) = b + ca = (b + c)/(bx - 1)I'm dumb, please help me.

i guess you have to find square root of every number
like of 15 is 3,87 therefore higher than it is 4 and less than it 3
Answer:
4 and 35 and 43 and 27 and 610 and 911 and 10Step-By-Step Explanation: (Rounded to nearest hundred)
Square Root 15 = 3.87; rounded up: 4, rounded down: 3Square Root 24 = 4.90; rounded up: 5, rounded down: 4Square Root 7 = 2.65; rounded up: 3, rounded down : 2Square Root 48 = 6.93; rounded up: 7, rounded down: 6Square Root 83 = 9.10; rounded up: 10, rounded down: 9Square Root 105 = 10.24; rounded up: 11, rounded down: 10A 40-degree angle is translated 5 inches along a vector. What is the angle measurement, in degrees, of the Image?
Answer:
40°
Step-by-step explanation:
As clarified in an online document, a translation along a vector (which is a line in a plane) of a figure, is equivalent to a translation along a coordinate grid, and therefore, given that a translation is a form of rigid transformation, the the dimensions and inclinations of the rays forming the preimage are the same as those in the image and the angles measurement in the preimage and the image are equal.
Therefore, given that the angle measurement of the image is 40-degrees, the angle measurement of the image is also 40-degree (40°) angle.
is a 4 sided polygon a rectangle
Answer: A rectangle is a 4-sided polygon where all four of its angles are right angles. Normally, the longer side is called the length and the shorter side is called the width. If all the sides are of equal length then it will be called a square. Area of rectangle = length × width.
Exlpination: A polygon is a closed figure with three or more straight sides. For example, a triangle is a polygon with three sides, a rectangle is a polygon with four sides, and a pentagon is a polygon with five sides.
Answer:
its a rectangle yea have a nice time
2x-y=1
x-y=-2
......................................
Answer:
y=5 x=3
Step-by-step explanation:
x-y=-2 move the y over to isolate x
x=-2+y Now plug that in for x in the first equation
2(-2+y)-y=1 Distribute
-4+y=1 Add 4 on both sides
y=5
x-5=-2
x=3

Find the area of each circle
. Round to the nearest tenth.
Answer:
13: 312yd squared
14: 907.5 rounded up but not rounded is 907.46
Step-by-step explanation:
this is because the formula is pi*r^2 so you'd
Step by step:
1. 20yd/2= 10 to get the radius for 13
2. substitute r in the formula pi*r^2 for 10 making it pi*10^2
3. multiply 10 by itself, 10*10=100
4. multiply pi by 100, 3.14*100= 314
314yd^2 is the answer for 13
14:
1. 34ft/2=17 to get the radius for 14
2. substitute r on the formula pi*r^2 for 17 making it pi*17^2
3. multiply 17 by itself, 17*17=289
4. multiply pi by 289, 3.14*289=907.46
5. round 907.46 to the nearest tenth, 907.5
907.5ft^2 is your answer
