Rewrite 72.3 + (-39.1) by breaking up each of the place values. In this case, the place values are tens, ones, and tenths.
72.3 - 39.1 = 4 tens - 7 ones - 2 tens is the correct order after rewriting.
Given the formula 72.3 + (-39.1)
removing the parentheses:
= 72.3 + (-39.1) (-39.1)
= 72.3 - 39.1
converting decimal numbers to place values
72.3 = 7tens plus 2units plus 3tenths
72.3 = 7(10) (10)
+2(1)+3(1/10)
72.3 =70+2+0.3
Similarly, 39.1
39.1 = 3tens plus 9units plus 1tenth
39.1 = 3(10)+9(1)+1(1/10)
39.1 =30+9+0.1
72.3 - 39.1 = 70+2+0.3 - (30+9+0.1)
72.3 - 39.1 = 70+2+0.3 - 30-9-0.1
72.3 - 39.1 = 70-30+2-9+0.3-0.1
72.3 - 39.1 = 40 - 7 +0.2
Hence after rewriting we get 72.3 - 39.1 = 4 tens - 7 ones - 2 tens

Jake has 30 fish in his aquarium. Emi has 1/3 the number of fish that Jake has and 1/2 the number of fish that Tobin has.
If the three students combined all their fish in the school's new aquarium, how many fish would there be?
Using Linear equation, The total number of fishes in the aquarium is found to be 50.
What is an linear equation in one variable?Linear equation is an equation containing one unknown variable with power one and constants.
The standard form of an linear equation in one variable x is :
ax + b = 0 , where a, b are constants
x= -b/ a is solution if this equation or we can solve this equation by adding or subtracting, multiplying, dividing same number to both sides.
Given that number of fishes jake has in the aquarium = 30
And that number of fishes Emi has is 1/3 the number of fish that jake has .
Therefore, Number of fishes that Emi has = 1/3 (30) = 10
Also given that Emi has 1/2 the number of fish that Tobin has .
Let Tobin has x fishes
⇒ 1/2(x) = Number of fishes Emi has
⇒ (1/2)x = 10, this is an linear equation in x
Multiplying both sides by 2, We get:
⇒ 2× (1/2)x = 2 ×10
⇒ x = 20
∴ Tobin has 20 fishes
If the three students combined all their fish in the school's aquarium,
the Total number of fishes = 30+20+10 = 50

Which answer is an equation in point-slope form for the given point and slope?
Point: (5, 9); Slope: 2
Responses
y−9=2(x−5)
y−5=2(x+9)
y−9=2(x+5)
y+9=2(x−5)
The equation which forms the correct slope-point form equation is
y - 9 = 2( x - 5). Thus, option (1) is the answer.
The point-slope form is a method that uses the slope of the line and a random coordinate on any point of the line to create an equation of that line.
The equation in the point-slope form is written in the format: [tex]y-y_{1}=m(x-x_{1})[/tex] , where m is the slope and [tex]x_{1}[/tex] and [tex]y_{1}[/tex]are the coordinates of the point on the line.
The given slope is 2, the x-coordinate is 5, and the y-coordinate is 9. There will be no addition symbol in the equation. There is only a subtraction of the coordinates in the equation form. Since options 2, 3, and 4 have addition signs, they do not show the correct equation.

Beth owns a coffee shop. She uses half a litre of mayonnaise each day. Mayonnaise costs £2.35 for a 1 litre jar and £4.65 for a 2 litre jar. Beth buys enough mayonnaise to last for 14 days. What is the lowest price Beth can buy this mayonnaise for? Show your working.
Answer:
£16.30
Step-by-step explanation:
0.5*14=7 litres for 2 weeks
The total cost to buy 7 litres = 7 × 2.35 = 16.45
The cost of 7 litres with the 1 litre jars is £16.45
The total cost to buy 7 litres = (4.65 × 3) + 2.35 = 16.30
The cost of 7 litres with the 2 and 1 litre jars is £16.30
16.45-16.30=15p
The lowest price Beth can buy this mayonnaise for £16.30.

4.17. for a standard normal random variable z, compute (a) p(z ≥ 0.99) (b) p(z ≤ −0.99) (c) p(z < 0.99) (d) p(|z| > 0.99) (e) p(z < 10.0) (f) p(z > 10.0) (g) with probability 0.9, variable z is less than what?
Answer: 1.28
Step-by-step explanation:
1. P(Z > 0.99) = 1 -Ф (0.99) = 1-0.8389 = 0.1611
2.P(Z <-0.99) = Ф(-0.99) = 0.161 (known that from [a] by symmetry)
3.P(Z <0.99) = Ф(0.99) = 0.8389
4. P(Z >0.99) = P(Z <-0.99) + P(Z > 0.99) = 2(0.1611) = 0.3222
The value z = 10.0 is out because it is too large. On comparing with the largest value, z = 3.99,
we get
5. P(Z < 10.0) > P(Z <3.99) = 1.0
6.P(Z > 10.0)<P(Z > 3.99) =10.0
7. On solving the equation
Ф(Z) = 0.9
for Z.
In Table A4, find the value of z corresponding to the probability 0.9. The nearest value is Ф(1.28) = 0.8997. Therefore, z ≈ 1.28

Given:
acorn is falling from 13 feet
Every seconds it descends = 4.8 feet
let us assume that the equation for the distance between the acorn from the ground is
x =13 - 4.8 y
where is y is time in seconds and x is the distance
if x = 1 foot

The value for g is 2, meaning that each family bowled 2 games.
How to solve linear equations?
Given that the largest power of the variable (or pronumeral) in these equations is 1, linear equations are also known as first-degree equations. A line on the quadratic system is represented by a linear equation. This equation's general form is axe + b = 0, where a, b, and x are all integers and x is the variable. The y-axis is parallel to this form of equation's single solution, which it symbolizes.
The steps that should be followed while solving linear equations are listed below:
1) We must first determine which variable we need to isolate.
2) Next, make a distinction between variables and constants.
3) Arrange the constants on the right and the variables on the left.
4) Using established axioms, we carry out algebraic operations to determine the variable's value.
Given, the equation is 6(8g + 2) + 45 = 153
Following the steps in the available literature, we have the equation as:
6(8g + 2) + 45 = 153 ⇒ 48g + 12 + 45 = 153 ⇒ 48g = 153 - 45 - 12 = 96
⇒ g = 96/48 ⇒ g = 2
Thus, g as suggested will determine number of times each family bowled.

What is coordinate geometry?A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.
The y-intercept of the first graph:-
y = mx + c
m= ( y₂ - y₁ ) / ( x₂ - x₁ )
m = ( 350 - 50 ) / ( 4 ) = 75
y = mx + c
50 = 75 x 0 + c
c = 50
The y-intercept of the second graph:-
y = mx + c
m= ( y₂ - y₁ ) / ( x₂ - x₁ )
m = ( 30 - 12 ) / ( 4 ) = 4.5
y = mx + c
12 = 4.5 x 0 + c
c = 12
The y-intercept of the third graph:-
y = mx + c
m= ( y₂ - y₁ ) / ( x₂ - x₁ )
m = ( 6 - 3 ) / ( ( 8 - 4 ) = 3 / 4

What is distance?
Distance is how much ground travelled by an object during its motion.
Here,
For River Edge
Number of animals seen = 8
Length of hike = 3 km
Number of Animals seen per km = 8/3
=2.66
For Wooden Marsh
Number of animals seen = 24
Length of hike = 8 km
Number of Animals seen per km = 24/8
=3
For Canyon Creek
Number of animals seen = 35
Length of hike = 15 km
Number of Animals seen per km = 35/15
