What are 3 consecutive multiples of 3 if 2/3 the sum of the first two numbers is 1 greater than the third number?
Answer:
the numbers are 15, 18, 21
Step-by-step explanation:
let the 3 consecutive multiples of 3 be:
3x, 3(x+1), 3(x+2)
(2/3)(3x + 3(x+1)) =3(x+2)+1
(2 /3)(6x+ 3) = 3x+6+1
2(2x+1) = 3x + 7
4x + 2 = 3x + 7
x = 5
so:
3x = 15
3(x+1) = 18
3(x+2) = 21
the numbers are 15, 18, 21

Assume that adults have IQ scores that are normally distributed with a mean of and a standard deviation . Find the probability that a randomly selected adult has an IQ less than . The probability that a randomly selected adult has an IQ less than is
Answer:
the probability when the IQ is lower than 136 is 0.9641
Step-by-step explanation:
Given that
The mean is 100
The standard deviation is 20
We need to find out the probability when the IQ is lower than 136
So,
z value equivalent to 136 = (136 - 100) ÷ 20 = 1.8
Now
p (z < 1.8) = 0.9641
hence, the probability when the IQ is lower than 136 is 0.9641

parallel lines
EP and CD
perpendicular lines
GH and EF
neither parallel nor
perpendicular lines
AB and CD
Answer:
Parallel = AB and CD
Perpendicular = EF and CD
Neither: GH and EF
Step-by-step explanation:
Parallel lines will go on forever without touching, they are aligned with each other.
Perpendicular lines intersect with 4 right angles
The Parallel lines are AB and CD and Perpendicular lines are EF and CD.
It is required to find the solution.
What is line?A line is a straight one-dimensional figure having no thickness and extending infinitely in both directions. A line is made of a set of points which is extended in opposite directions infinitely. It is determined by two points in a two-dimensional plane. The two points which lie on the same line are said to be collinear points.
Given:
The given figure shown as four lines are given AB , CD ,EF , CD ,GH and EF.
According to given question we have
Parallel = AB and CD
Perpendicular = EF and CD
Neither parallel nor perpendicular lines: GH and EF
Parallel lines are those lines that are equidistant from each other and never meet, no matter how much they may be extended in either directions
Perpendicular lines are lines that intersect at a 90-degree angle.
Therefore , the Parallel lines are AB and CD and Perpendicular lines are EF and CD.

PLEASE HELP) Given the function ƒ(x) = x and the function g(x) = x – 4, what does the –4 do to the graph of ƒ(x) to get the graph of g(x)?
Answer:
C. Translates the graph 4 units downwards
Step-by-step explanation:
The -4 is the y-intercept which brings the graph down four units
In the function f(x)=[tex]\sqrt{x}[/tex]-4, -4 shows the translation of graph units downwards which is option c.
What is function?Function is relationship between two or more that are variables that are expressed in equal to form. In a function each value of x must have a corresponding value of y which is known as codomain of function.
How to find function?In the function f(x)=[tex]\sqrt{x}[/tex]-4, -4 decreases the value of function by 4 units and because the y axis is vertical line. So the value which is -4 pulls the function downwards by 4 units and this process is known as translation.
Hence in the function f(x)=[tex]\sqrt{x}[/tex]-4, -4 shows the translation of graph units downwards which is option c.

Find the radius of a circle that has a sector area of 15.2 ft2 and a central angle
measure of 90°
Answer:
4.399231874 or radical (60.8/pi)
btw radical is square root
Step-by-step explanation:
Since the area of 1/4 (90/360) of the circle is 15.2 ft^2, the area of the whole circle must be
15.2*4 = 60.8.
Now, we can work backwards to find the radius using the are formula. Let's say the radius is x.
x^2pi = 60.8
x^2 = 60.8/pi
x = radical(60.8/pi)

The screen at Dallas’ AT&T Stadium is 175 feet wide. A movie theatre screen with similar dimensions is 40 feet wide with a screen area of 1,024 ft². What is the area of the screen at AT&T Stadium? Round to the nearest square foot.
Answer:
The area of the screen at AT&T Stadium is 4,480 square feet.
Step-by-step explanation:
Given that the screen at Dallas' AT&T Stadium is 175 feet wide, and a movie theater screen with similar dimensions is 40 feet wide with a screen area of 1,024 ft², to determine what is the area of the screen at AT&T Stadium the following calculation must be done:
40 = 1,024
175 = X
175 x 1,024 / 40 = X
179,200 / 40 = X
4,480 = X
Thus, the area of the screen at AT&T Stadium is 4,480 square feet.

The volume of the cone is 1004.8 cm³
What is volume?The amount of space occupied by a three-dimensional figure as measured in cubic units.
given: l= 17 cm and r =8 cm
h= √l²-r²
= √17²-8²
=√289-64
= √225
h=15 cm
Volume of cone =1/3* π* r²*h

but i used this form ; 3x + 2iy+ xi + 5y = 7 + 5i instead of 3x+2iy xi+5y =7+5i
Then ;
you compare
3x + 5y =7....... equation 1
2iy + xi = 5i. ( cancel out i)
u get ; 2y + x =5 .......equation2
solve simultaneously by substitution method
giving u y=8
put value of y into equation 2 and get x=-11
