Answer:
The two numbers are 32 and 60.
Step-by-step explanation:
We can create two simultaneous equations to solve this problem using the information given in the question.
Let number 1 = x
Let number 1 = y
x = y - 28 -> ( 1 )
x + y = 92 -> ( 2 )
We can solve simultaneous equations using substitution or elimination. For this question, we will use substitution as it is the easier option.
Substitute ( 1 ) into ( 2 ):
x + y = 92 -> ( 2 )
( y - 28 ) + y = 92
2y - 28 = 92
2y = 120
y = 120 / 2
y = 60 -> ( 3 )
Substitute ( 3 ) into ( 1 ):
x = y - 28 -> ( 1 )
x = ( 60 ) - 28
x = 32
Therefore:
x = 32 , y = 60

The question is an illustration of linear equation, and the solution to the linear equation is x = -5
How to determine the solution?The equation is given as:
[tex]\frac 23x - \frac 12 = \frac 13 + \frac 56x[/tex]
Multiply through by 6
4x - 3 = 2 + 5x
Collect like terms
4x - 5x = 2 + 3
Evaluate the like terms
-x = 5
Divide both sides by -1
x = -5
Hence, the solution to the linear equation is x = -5

Solve for y in terms of x. 16x + 4/3 y = 21
Answer:
y= -12x+63/4
Step-by-step explanation:
16x + 4/3 y = 21
4/3 y =21-16x
4y=3(21-16x)
4y=63-48x
y=63/4-48/4 x

7x - 17 = 4x + 1
-x + 5 = x - 11
5x + 8 = 7x + 2
Combine the same numbers and do the opposite of either subtraction or addition.
Then, multiply or divide with the coefficient.
Answer:
see below
Step-by-step explanation:
⇒ 7x - 17 = 4x + 1
combine like terms
7x - 4x = 1 + 17
3x = 18
x = 18/3
x = 6
⇒ -x + 5 = x - 11
combine like terms
- x - x = - 11 - 5
-2x = -16
x = 16 / 2
x = 8
⇒ 5x + 8 = 7x + 2
combine like terms
5x - 7x = 2 - 8
- 2x = - 6
x = 6 / 2
x = 3

Consider the point. (1, 4, 5) What is the projection of the point on the xy-plane?
Given :
A point ( 1 ,4 ,5 ).
To Find :
The projection of the point on the xy-plane .
Solution :
Now , to find projection of a point in a plane in a plane we need to replace the coordinate of that remaining axis which is not in the plane .
Here , the plane given is xy-plane . So , remaining axis is z .
So , we replace coordinate of z =0 .
Therefore , the projection of the point ( 1 ,4 ,5 ) on the xy-plane is ( 1 ,4 ,0 ) .
Hence , this is the required solution .
which of the following sets of numbers could represent the three sides of a triangle
A 6,20,28
b 4,11,15
c 9,19,30
d 5,15,19
Answer:
d 5,15,19
Step-by-step explanation:
The sum of the shortest two sides must be longer than the longest side. That is only the case for selection D.
__
If the sum is equal to the longest side, the segment ends will meet, but the "triangle" will look like a line segment. Many authors do not allow such a thing to be called a triangle. Hence, 'b' is not an answer to this question.
(Some authors do allow such a triangle, in which case, there would be two answers here: B and D.)

The volume of a volleyball is about 288 cubic inches. what is the radius of the volleyball, to the nearest tenth of an inch? use 3.14 for π.
[tex]r = \sqrt{ \frac{3v}{4\pi} } [/tex]
Answer:
The radius of the volleyball is 8.3 inches
Step-by-step explanation:
Given
[tex]r = \sqrt{\frac{3v}{4\pi}}[/tex]
[tex]v = 288[/tex]
Required
Determine the value of r
To do this, we simply substitute 288 for v and 3.14 for π in the given equation.
This gives
[tex]r = \sqrt{\frac{3v}{4\pi}}[/tex]
[tex]r = \sqrt{\frac{3 * 288}{4 * 3.14}}[/tex]
[tex]r = \sqrt{\frac{864}{12.56}}[/tex]
[tex]r = \sqrt{68.7898089172}[/tex]
[tex]r = 8.29396219651[/tex]
[tex]r = 8.3\ inch[/tex] (Approximated)
Hence;
The radius of the volleyball is 8.3 inches
Answer: 4.1 inches

How to express a vector as a product of its length and direction?
Answer:
So the way to express a vector( [tex]v = 2i - 2j - 2k[/tex]) as a product of its length and direction is
[tex]v = |v| u = \sqrt{12} (\frac{2}{ \sqrt{12} } , -\frac{2}{ \sqrt{12} }, - \frac{2}{ \sqrt{12} })[/tex]
Step-by-step explanation:
Generally a vector is expressed as a product of its length and direction using the formula below
[tex]v = |v|\cdot u[/tex]
Here v is the vector
|v| is its magnitude (length)
u is its unit vector (direction)
Now let take an example
Let
[tex]v = 2i - 2j - 2k[/tex]
The magnitude is mathematically evaluated as
[tex]|v| = \sqrt{ 2^2 + (-2)^2 + (-2)^2 }[/tex]
[tex]|v| = \sqrt{12}[/tex]
The unit vector is mathematically represented as
[tex]u = \frac{v}{|v|}[/tex]
[tex]u = \frac{ <2 , -2 , -2>}{\sqrt{12} }[/tex]
[tex]u = \frac{2}{ \sqrt{12} } , -\frac{2}{ \sqrt{12} }, - \frac{2}{ \sqrt{12} }[/tex]
So
[tex]v = |v| u = \sqrt{12} (\frac{2}{ \sqrt{12} } , -\frac{2}{ \sqrt{12} }, - \frac{2}{ \sqrt{12} })[/tex]

Answer:you need to multiply it by 4.
Step-by-step explanation:
If the number is multiplied by 4 it square root is effectively doubled.
Example: if you take the square root of 64, its 8.
to double the square root, you multiply 64 by 4---> 256.
And the square root of 256, is 16, double that of the square root of 64.

Which equation can be used to solve for x in the following diagram? Choose 1 answer:
Answer:
D) 60=(x+45)
Step-by-step explanation:
D. Since the two are equal, you need to put the two on opposite sides of the equation. The equation doesn’t involve 90 or 180 degrees, so no reason to have them.
Solving for x this way, you’d get 15, which is correct.

3. At the start of summer, Ben has $250 . He takes a summer
job and saves $ 150 per week. Tim has $ 1,650 at the start of
summer , he travels and spends $ 200 per week. At the end of
which week do Ben and Tim have the same amount of money ?
Answer:
Week 4
Step-by-step explanation:
Ben has $250 in the beginning. He saves $150 per week.
y = 150x + 250
Tim has $1,650 in the beginning. He spends $200 per week.
y = 1650 - 200x
We are trying to find which x-value produces the same y-value for both equations. You can do this by setting both equations equal to each other.
150x + 250 = 1650 - 200x
(150x + 250) + 200x = (1650 - 200x) + 200x
350x + 250 = 1650
(350x + 250) - 250 = (1650) - 250
350x = 1400
(350x)/350 = (1400)/350
x = 4
By week 4, they will have the same amount of money.
