Jacob and Kerrie are trying to figure out how long they can live off their $84,670 savings if they spend $370 each month. They have each created an equation. Jacob's Equation Kerrie's Equation y = 84,670 + (370x) y = 84,670 − (370x) Which person has the correct equation to model this linear relationship?
A.Kerrie's equation is incorrect, because their spending will increase the amount of their savings. B.Kerrie's equation is correct, because their spending will be multiplied by the number of months and then subtracted from their savings. C.Jacob's equation is correct, because their spending will be multiplied by the number of months and then subtracted from their savings. D.Jacob's equation is incorrect, because their spending should be a fixed amount and should not be multiplied.
Answer:
B.)Kerrie's equation is correct because their spending will be multiplied by the number of months and then subtracted from their savings
Step-by-step explanation:
Given : Jacob and kerrie are trying to figure out how long they can live off their 84,670 savings if they spend 370 each month.
To Find: Which person has the correct equation to model this linear relationship?
Jacob's equation : y = 84,670+(370x).
Kerrie's equation : y=84,670-(370x).
Since they have 84670 in savings
They spend each month = 370
They spend in x months = 370x
So, spending this amount from saving they left with amount = 84,670-(370x)
Thus Kerrie's equation is correct .
Hence Option B is correct
B.)Kerrie's equation is correct because their spending will be multiplied by the number of months and then subtracted from their savings

Abag of peanuts is 5 times as heavy as a bag of sunflower seeds. The bag of peanuts
also weights 920 grams more than the bag of sunflower seeds. What is the total weight
in grams for the bag of peanuts and the bag of sunflower seeds?
Answer:
5s=p
s+920=p
5s=s+920
*subtract s from both sides*
4s=920
*divide 4 from both sides*
s=230
230*5=1150
The bag of sunflower seeds weighs 230 grams and the bag of peanuts weighs 1150 grams.
9514 1404 393
Answer:
1380 grams
Step-by-step explanation:
The ratio of weights is ...
peanuts : sunflower seeds = 5 : 1
Then the difference in weights is ...
5 - 1 = 4 . . . . ratio units
The sum of weights is ...
5 + 1 = 6 . . . . ratio units
That is the sum of the weights related to the difference of weights is ...
sum : difference = 6 : 4 = 3 : 2
So, the total weight of the two bags is 3/2 times the difference in their weights:
total weight = (3/2)(920 grams) = 1380 grams

What is the value of the expression when a = –5 and c = –1? The expression is 8(a + 2c)
Answer:
8(a + 2c) = -56
Step-by-step explanation:
Given that,
An expression : 8(a + 2c)
We need to find the value of the above expression when a = -5 and c = -1.
Put the values of a and c in the given expression.
8(a + 2c) = 8(-5+2(-1))
= 8(-5-2)
= 8(-7)
= -56
Hence, the value of the given expression is -56.

Add 8x to both sides.
x^2+14=10x-7
Add 7 to both sides.

Cathy would like to have accumulated $25,000 on her IRA account in 5 years. The return is 3.1%. How much should Cathy deposit in her account annually?
$1,329.94
$2,711.73
$4,699.46
$5,000.00
Answer:
Annual deposit= $4,699.46
Step-by-step explanation:
Giving the following information:
Future value (FV)= $25,000
Number of periods (n)= 5 years
Interest rate (i)= 3.1% = 0.031
To calculate the annual deposit, we need to use the following formula:
FV= {A*[(1+i)^n-1]}/i
A= annual deposit
Isolating A:
A= (FV*i)/{[(1+i)^n]-1}
A= (25,000*0.031) / [(1.031^5) - 1]
A= $4,699.46
The blue segment below is a radius of oo. What is the length of the diameter
of the circle?
A. 4.9 units
B. 14.7 units
C. 9.8 units
D. 19.6 units
Answer:
D. 19.6 unitsStep-by-step explanation:
diameter = 2r
where r = 9.8
plugin value of r = 9.8 into the formula:
diameter = 2(9.8)
= 19.6 units
The length of the diameter of the circle is option D 19.6 units.
What is the diameter?Diameter is defined as the line from one point in the circle to the other point through the center of the circle.
WE know that the diameter = 2r
where r = 9.8
Substitute value of r = 9.8 into the formula:
The diameter = 2(9.8)
The diameter = 19.6 units
Hence, the length of the diameter of the circle is option D 19.6 units.

A:
density = mas/volume = 42 g / 2 cm^3 = 21 g/cm^3
This may be platinum.
B.
density = mass/volume = 87.5 g / 5 cm^3 = 17.5 g/cm^3
This cannot be pure platinum.

Answer:
Step-by-step explanation:
We know the slope is rise over run. You can also find slope by using the formula (y2-y1)/(x2-x1) where x1, x2, y1 and y2 are points from the table. These points also aren't random and must correspond with each other. Example x1 and y1.
A pet store has three fish tanks, each holding a different volume of water and a different number of fish. Tank A has 5 fishes with a volume of 40 liters. Tank B has 12 fishes with a volume of 100 liters. Tank C has 23 fishes with a volume of 180,000 milliliters. Which tank has the greatest volume per fish?
Answer:
Tank B
Step-by-step explanation:
A pet store has three fish tanks, each holding a different volume of water and a different number of fish.
a) Tank A has 5 fishes with a volume of 40 liters.
Volume per fish = 40 liters/5 fishes
= 8 liters/fish
b) Tank B has 12 fishes with a volume of 100 liters.
Volume per fish = 100 liters/12 fishes
= 8.33 liters/ fish
c) Tank C has 23 fishes with a volume of 180,000 milliliters.
Convert 180,000 milliliters to liters
1 milliliter = 0.001 liter
180,000 milliliters = x
x = 180,000ml × 0.001 l
x = 180 liters
Volume per fish = 180 liters/23 fishes
= 7.8260869565 volume per fish
Approximately = 7.83 liters/fish
Which tank has the greatest volume per fish?
The tank that had the greatest volume per fish is Tank B at 8.33 liters/ fish
Solve for x:16^(4x-3)=8^(2x+4)
Answer:
x = 2.4
Step-by-step explanation:
16^(4x - 3) = 8 ^ (2x + 4)
16 = 2^4
8 = 2^3
2 ^ 4*(4x - 3) = 2^3(2x + 4)
Since the bases are the same, you can equate the powers
4(4x - 3) + 3*(2x + 4) Remove the brackets.
16x - 12 = 6x + 12 Subtract 6x from both sides
16x - 6x - 12 = 12 Combine the terms on the left
10x - 12 = 12 Add 12 to both sides
10x = 24 Divide by 10
x = 2.4

The population of bears in a national forest is changing according to the function N(t)=850(1.04)t , where t is the time in years, and N(t) is the number of bears. Which statement explains how the bear population is changing?
Answer:
The statement is that the population increases at a rate of 4% per year
Step-by-step explanation:
The function is given as;
N(t) = 850(1.04)^t
The general equation form for a representation as this is;
P = I(1 + r)^t
Where I is the initial value and P is the present value
r is the rate of increase
t is the time
Thus, we have that;
1 + r = 1.04
r = 1.04-1
r = 0.04
0.04 is same as 4/100 which is same as 4%
So the statement about how the population of bear is changing is that the population increases at a rate of 4% each year

Step-by-step explanation:
The given shape is a pentagon, an irregular polygon, and also convex.
What is a polygon?A Polygon is considered to be Concave if its diagonal can lie outside the Polygon as well.
A polygon is considered to be Convex if all of its diagonals lie within it.
A polygon is considered to be regular if it is convex and has equal sides and angles.
If all of the angles and sides of a polygon are not equal, it is said to be irregular.
Here,
The given shape has five sides, which means this is a pentagon.
The given shape has unequal sides, which means this is an irregular pentagon.
The given shape has it's all its diagonals lying inside, which means this is a convex pentagon.
