Work out how much more Ivan gets compared to Tanya.
Answer:
Step-by-step explanation:
The £150 must be split 5 ways with Ivan getting 4 of those splits.
£150/5

Ivan gets £30 times 4 (remember, Ivan gets a four split).
Tanya gets £30.
Ivan gets £120.
Tanya gets £30.
£120

As one object gets closer to another object the force of gravity will increase?
Answer:
no
Step-by-step explanation:
gravity is relevant to when something is being affected by the gravitational pull on earth, or any other planet. for example, i throw an apple into the air. and it comes back down, as newton said. what must come up, must come down. because of gravity, two objects being closer together does not affect the gravitational pull whatsoever. and the force of gravity doesn't change. as gravity just works on it's own, independent of the object, not dependent on the object. however certain objects will fall abit faster than others.

What is an
equation of the line that passes through the points (-5, 8) and
(5,0)?
Answer:
y=4/5x-4
Step-by-step explanation:
use formulas (y2-y1)/(x2-x1) and y=mx+b
slope (y2-y1)/(x2-x1):
(8-0)/(5-(-5))
=8/10
=4/5
equation (y=mx+b):
0=4/5(5)+b
0=4+b
b=-4
A line passes through the points (4,9) and (12,20) what is the slope of the line?
Answer:
11/8
Step-by-step explanation:
[tex]slope = \frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]
20 - 9 = 11
12 - 4 = 8
slope = 11/8
Translate the given phase into an algebraic expression and simplify if possible: the quotient of -20 and -40.
Answer:
0.5
Step-by-step explanation:
-20 and -40
quotient means divide one another
-20 / -40
= 20/40
= 2/4
= 0.5
I made these into tiny tiny steps, enjoy.
The translation of the simplified algebraic expression for "the quotient of -20 and -40" is [tex]\dfrac{1}{2}[/tex].
A collection of constants, variables or numbers connected using one or more arithmetic operator is called an algebraic expression .
Example = 4y, 3x+4.
The quotient of -20 and -40 can be written as:
[tex]\dfrac{-20}{-40}[/tex]
The expression can be simplified in the lowest form as;
[tex]\dfrac{-20}{-40}[/tex] = [tex]\dfrac{1}{2}[/tex]
So, the simplified algebraic expression for "the quotient of -20 and -40" is [tex]\dfrac{1}{2}[/tex].

Two chemical plants, one at Macon and one at Jonestown, produce two types of fertilizer, low phosphorus (LP) and high phosphorus (HP). At each plant, the fertilizer is produced in a single production run, so the two types are produced in fixed proportions. The Macon plant produces 1 ton of LP and 3 tons of HP in a single operation, and it charges $600 for what is produced in one operation, whereas one operation of the Jonestown plant produces 1 ton of LP and 1 ton of HP, and it charges $1,000 for what it produces in one operation. If a customer needs at least 100 tons of LP and 180 tons of HP, how many production runs from each plant should be ordered to minimize the cost.
Answer:500
Step-by-step explanation:
There are 100 production runs from each plant should be ordered to minimize the cost.
What is Production?
The process of making or manufacturing goods and products from raw materials or components is called Production.
The Macon plant produce 1 ton of LP and 3 tons of HP in single operation, and it charge $600 for what is produced in one operation.
And, One operation of Jonestown plant produce 1 ton of LP and 1 ton of HP, and it charges $1,000 for what it produces in one operation.
And, A customer needs at least 100 tons of LP and 180 tons of HP,
Now, A graph of the requirements shows the feasible region is bounded by a polygon with vertices (Macon and Jonestown) as,
= (0, 180), (40, 60), (100, 0).
Hence, By checking costs of these solutions, we find the lowest cost to be obtained when 100 production runs should be ordered from Macon.
So, There are 100 production runs from each plant should be ordered to minimize the cost.

M
J 9x + 1 L
Answer:
Since they are similar their sides are corresponding,
9x + 1 / x + 5 = 49 / 14
or, 14 ( 9x + 1 ) = 49 ( x + 5 ) { cross multiply}
or, 126x + 14 = 49x + 245
or, 77x = 231
or, x = 231/77

Four friends go to dinner. Each chooses a different meal. When the check comes, they decide they will each pay the same amount. If the costs of the meals (including tax and tip) were $12.20, $11.00, $8.50, and $7.50, what should each friend pay so they cover the whole bill?
Answer: Each friend should pay $9.80
Step-by-step explanation: First add up all their checks, then divide them by 4 (4 because there 4 friends) to get the amount each friend needs to pay.
$12.20 + $11.00 + $8.50 + $7.50= $39.20
39.30 / 4 = $9.80
