Answer:
The faster computer will complete the job in 20 minutes alone.
Step-by-step explanation:
Given that:
Time taken by both computers = 12 minutes
Time taken by slower computer = 30 minutes
Let,
x be the time taken by faster computer.
[tex]\frac{1}{x}+\frac{1}{30} = \frac{1}{12}[/tex]
[tex]\frac{1}{x} = \frac{1}{12}-\frac{1}{30}\\\\\frac{1}{x} = \frac{5-2}{60}\\\\\frac{1}{x} = \frac{3}{60}\\\\\frac{1}{x} = \frac{1}{20}\\\\x= 20[/tex]
Hence,
The faster computer will complete the job in 20 minutes alone.

(05.05) On a coordinate plane the coordinates of vertices R and T for a polygon are R(-7, 3) and T(3,3). What is the length of Side RT of the polygon?
4 units
6 unts
10 units
15 units
PLEASE HELP!!
Answer:
c) 10 units
The length of side RT of the polygon RT = 10
Step-by-step explanation:
Step(i):-
Given the coordinates of vertices R and T
R( -7 ,3) and T (3 ,3)
we have to find the length of side RT
We will use distance formula
RT = [tex]\sqrt{(x_{2} -x_{1})^{2} +(y_{2} -y_{1} )^{2} }[/tex]
Step(ii):-
RT [tex]= \sqrt{(3-3)^{2} +(3-(-7))^{2} }[/tex]
[tex]RT = \sqrt{0+(10)^{2} }[/tex]
RT = √100
RT = 10
The length of side RT of the polygon RT = 10

What is square pyramid?A square pyramid has a square base and four lateral faces in geometry. A pyramid is a polyhedron with a base and three or more triangular faces that meet above it . A square pyramid, also known as a pentahedron, is a three-dimensional geometry with a total of five faces.
How to solve?As ancient pyramid models were in shape of square pyramid hence we apply
[tex]A = a(a + \sqrt{ (a^{2} + 4h^{2} ))}[/tex]
where a =25cm
and h=30 cm
[tex]A = 25(25 + \sqrt{ (25^{2} + 4(30^{2}) ))}[/tex]
=25(25+65)
=2250[tex]cm^{2}[/tex]

Last night you went to a restaurant, and the bill for 3 adult meals and 2 children’s meals was £73.
Last week you went to the same restaurant and paid £89 for 2 adult meals and 5 children’s meals.
Let a = cost of an adult meal,
and c = cost of a child meal.
A) Form an equation for last night’s meal
? = ?
B) Form an equation for last week's meal
? = ?
Answer: 3a + 2c = 73 (last night)
2a + 5c = 89 (last week)

Given: Point C is the midpoint of AB¯¯¯¯¯.
AC=7x−10; CB=3x+10
Prove: AC=25
Drag and drop reasons into the boxes to correctly complete the proof.
Statement Reason
Point C is the midpoint of AB¯¯¯¯¯. Given
AC=7x−10; CB=3x+10 Given
AC=CB Definition of midpoint
7x−10=3x+10 Response area
4x−10=10 Response area
4x=20 Addition Property of Equality
x=5 Response area
AC=7(5)−10 Substitution Property of Equality
AC=35−10 Simplify.
AC=25 Simplify.
Answer:
See proof below
Step-by-step explanation:
If C is the midpoint of AB, then AC = CB
Given
AC=7x−10;
CB=3x+10
Then 7x - 10= 3x+10
Add 10 to both sides
7x-10+10 = 3x +10+10
7x = 3x + 20
7x - 3x = 10+10
4x = 20
x = 20/4
x = 5
Get AC
AC = 7x - 10
AC= 7(5) - 10
AC = 35-10
AC = 25 (Proved)
