the sum of three numbers is 124. the third number is 4 times the first. the second number is 10 more than the first what are the numbers
Answer:
19,29,76
Step-by-step explanation:
x=first number
x+10=second number
4x=third number
add three numbers to equal 124.
x+(x+10)+4x=124
6x=114
x=19 first number
x+10 0r
19+10=29 second number
4x or
4(19)=76 third number
19+29+76=124
124=124
A couch and coffee table cost a total of $1172. The cost of the couch is three times the cost of the coffee table. Find the cost of each item.
Answer:
x + 3x = 1172, where x is the cost of the coffee table and 3x equals the cost of the couch.
4x = 1172
x = 293
thus, 3x = 293
293 x 3= 879
The couch is $879 and the coffee table is $293
What is the area of a circle with a diameter of 14 meters? Leave the answer in terms of π.
49π square meters
7π square meters
196π square meters
14π square meters
Therefore , the solution of the given problem of circle comes out to be Area = 154 meter square or 49π meter square option 1 is correct.
Circle – what is it?A moving point on a plane is followed so that its distance from a specific point remains constant to produce the circular form known as a circle. The English term circle derives from the Greek word kirkos, which meaning hoop or ring. Area of circle= πr²
Here,
Given :
Diameter of circle : 14
Radius =14/2 = 7 meters
and
Using formula
Area= πr²
=> Area = π7²
=>Area = 22/7 * 7²
=> Area = 22*7
=> Area = 154 meter square or 49π meter square
Therefore , the solution of the given problem of circle comes out to be Area = 154 meter square or 49π meter square option 1 is correct.

A satellite dish is in the shape of a parabolic surface. Signals coming from a satellite strike the surface for the dish and are reflected to the focus, where the receiver is located. The satellite dish has a diameter of 14 feet and a depth of 3 feet. How far from the base of the dish should the receiver be placed? Round your answer to the nearest tenth.
Answer:
Given that we know the base of the parabola is at the origin, and that it is symetrical about the y-axis, we can simplify the equation to

+6x−8
The value of the expression 8x² + 6x - 8 below when x=2 is 36.
The value of the expression when x = 2The expression can be evaluated by following the steps below:
8x² + 6x - 8 in x = 2 means that the variable x will be replaced by the given number which is 2.
8*2² + 6*2 - 8
8*4 + 12 - 8
32 + 16 - 8 = 36
This therefore means that when x= 2 in 8x² + 6x - 8 , the value gotten will be 36.

Find a formula for RN for the function f(x) = (5x)² on [-1, 5] in terms of N.
Could you please show the work? I was able to get the area but can't exactly figure out what they want for the formula.
Compute the area under the graph as a limit.
lim RN=1050
Therefore , R(N) = 100 + 400 (N+1)(2N+1) + 800 x N2 N3 and area are the formulas for R(N) for the function f(x) = (5x)2 on [1, 5] and the function f(x) = (5x)2 in terms of N. R(N) = 767(approx) (approx).
What is function?Each x value in the domain has one but only one y value range, according to the rule of a function. Definition. If there is only one and only one value of x variable such that f(x) = y, then the function is one-to-one.
Here,
In the given question, we have to find a formula for R(N) for the function f(x) =(5x)^2 on [1, 5] in terms of N.
The given function is f(x)=(5x)^2 on [1, 5].
Ax = (5-1)/N
Ax = 4/N
X = 1+iAx
X = 1+i4/N
f(x) = 25X^2
f(x) = 25(1+i4/N)^2
f(x) = 25(1+i8/N+16/N^2 i^{2})
R(N) = 1ƒ(X) Ax
Now putting the value of f(x) and Ax
R(N)==1 [25 (1+ &i + 16i2)]
R(N) = 1001 (1 +Ni + 16i2)
N100 (1+i+12)N
100 (N += i +122)+16 N(N+1)(2N+1)(+1)(2N+1)
R(N)=100 (N + √2/ N(N+1) x 100
R(N) =2/6× N + 100 × 5 × N(N+1) + 100 x 2
[tex]\lim_{n \to \infty}[/tex] R(N) = 100 + 400 + 800/3
[tex]\lim_{n \to \infty}[/tex] R(N) = 766.67
[tex]\lim_{n \to \infty}[/tex] R(N) = 767(approx)
Therefore , the solution of the given problem of function comes out to be [tex]\lim_{n \to \infty}[/tex] R(N) = 767(approx).

Explain.
No Alisa do not have enough fence.
What is perimeter?The perimeter of an object is given by adding the side lengths of the object.
Given that Alisa needs 4.65 feet of fencing to complete the fence she is building. She has a piece of fencing that is 4 ft long.
We need to determine whether she have enough fencing or not,
Since we know that the fencing can be considered as perimeter of the building,
So, if she only has 4 ft long fence, she cannot cover a 4.65 ft long fence.
