Answer:
B. 6 x 0.8
Step-by-step explanation:
It depends on the placement of the decimal point. All of the answers have 6 x 8. It's just that the decimal points are in different places each time.
For example, option A, is 6 x 8, which is 48. 48 is not equal to 4.8.
Option B, however, has 6 x 0.8. 6 x 8 = 48, and divided by 10 is 4.8. 4.8 = 4.8. This means Option B is correct.

Sara ordered 2 slices of pizza and a 12-ounce cola and paid
$3.00. Sydney ordered 3 slices of pizza and 2 12-ounce
colas for $4.75. How much does a slice of pizza cost?
Answer: a slice of pizza cost $1.25 and a 12-ounce cola cost $0.50.
Step-by-step explanation:
Let slice of pizza cost x and a 12-ounce cola cost y.
Then Sara's order cost: 2x+y=3
and Sydney's order cost: 3x+2y=4.75
From the first equation we have: y=3-2x and put this to the second equation:
3x+2(3-2x)=4.75
3x+6-4x=4.75
x=1.25
y=3-1.25*2=0.50
Answer: a slice of pizza cost $1.25 and a 12-ounce cola cost $0.50.
A bowling alley has a one-time charge of $2.50 to rent a pair of shoes and a charge of $2.00 for each game bowled. The function f (x)
represents the total cost to bowl x games.
Which equation represents f (x)?
O A f(x) = 2.5x + 2
O B. f (x) = 2x + 2.5
O c f(x) = (2.5 + 2)x
OD. f (x) = (2.5 - 2)x
Answer:
B. f (x) = 2x + 2.5
Step-by-step explanation:
Linear function:
A linear function has the following format:
[tex]y = mx + b[/tex]
In which m is the value that y changes by when x increases by 1, and b is the flat fee.
A bowling alley has a one-time charge of $2.50 to rent a pair of shoes and a charge of $2.00 for each game bowled.
This means that [tex]m = 2, b = 2.50[/tex]
So
[tex]f(x) = 2x + 2.5[/tex]
And the correct answer is given by option b;

A man bought a certain number of golf balls for RM 20. If each ball has costed 20 cents less, he could have bought five more for the same money. How many golf balls did he buy?
Answer:
He bought 20 balls
Step-by-step explanation:
Cost of a certain number of golf balls = $20
Let 1 golf ball cost $x
This means number of balls bought = 20 / x
If each ball has costed 20 cents less;
Converting 20 cents to dollars = $0.2
$x - $0.2
he could have bought five more for the same money.
Number of balls = 20/x + 5
Using the formulae;
Cost of 1 ball * Number of balls bought = Amount spent
(x-0.2) (20/x + 5) = 20
Expanding the expression;
x(20/x + 5) - 0.2(20/x + 5) = 20
20 + 5x - 4/x - 1 = 20
19 + 5x - 4/x = 20
5x - 4/x = 1
Multiplying all through by x
5x^2 - 4 = x
5x^2 - x - 4 = 0
(5x + 4)(x - 1) = 0
x = 1 or -4/5
-4/5 is unrealistic hence the correct value is;
x = $1
He bought 20 balls; 20 / x = 20 / 1 = 20
The reduction in the price of each ball increases the number of balls the man can buy at RM 20.
The number of balls he bought is 20 balls.
Reasons:
The given parameters are;
The amount the man bought the golf balls = RM 20
The number of golf balls he could have bought if each ball costs 20 cents less = 5 more balls
Let the number of balls the man bought = x
Let the price of each ball be m
We have;
m × x = 20
(x + 5)·(m - 0.20) = 20
Therefore, we get;
[tex]m = \dfrac{20}{x}[/tex]
Which gives;
[tex]\left(x + 5 \right) \cdot \left(\dfrac{20}{x} - 0.20\right) = 20[/tex]
[tex]-\dfrac{\left(0.2 \cdot x^2- 19 \cdot x - 100\right)}{x} = 20[/tex]
20·x = -0.2·x² + 19·x + 100
0.2·x² + x - 100 = 0
x² + 5·x - 500 = 0
(x + 25)·(x - 20)
x = 20
The number of balls he bought, x = 20 balls

Answer:
[tex]h^{l} (s) = \frac{1 }{(\sqrt{s}) (1-\sqrt{s})^{2} }[/tex]
Step-by-step explanation:
Explanation
Given that
[tex]h(s) = \frac{1+\sqrt{s} }{1-\sqrt{s} }[/tex]
Differentiating equation (i) with respective to 'x' ,we get
[tex]h^{l} (s) =\frac{1-\sqrt{s}) \frac{1}{2\sqrt{s} } -(1+\sqrt{s})(\frac{-1}{2\sqrt{s} )} }{(1-\sqrt{s})^{2} }[/tex]
[tex]h^{l} (s) = \frac{\frac{1}{2\sqrt{s} } -\frac{1}{2\sqrt{s} }X\sqrt{s} + \frac{1}{2\sqrt{s} } +\frac{1}{2\sqrt{s} }X\sqrt{s} }{(1-\sqrt{s})^{2} }[/tex]
[tex]h^{l} (s) = \frac{\frac{2}{2\sqrt{s} } }{(1-\sqrt{s})^{2} }[/tex]
[tex]h^{l} (s) = \frac{1 }{(\sqrt{s}) (1-\sqrt{s})^{2} }[/tex]

Answer:
hurricane basics
Step-by-step explanation:
A "hurricane" is the most severe category of the meteorological phenomenon known as the "tropical cyclone."
Tropical cyclones are low pressure systems that have thunderstorm activity and rotate counterclockwise. A tropical
cyclone that has winds of 38 mph (33 kt) or less is called a tropical depression. When the tropical cyclone's winds reach
39-73 mph (34-63 kt), it is called a tropical storm. When the winds exceed 74 mph (64 kt), the storm is considered
to be a hurricane.
The Saffir-Simpson Hurricane Scale defines hurricane strength by categories. A Category 1 storm is the weakest hurricane
(winds 74-95 mph or 64-82 kt); a Category 5 hurricane is the strongest (winds greater than 155 mph or 135 kt).
The category of the storm does not necessarily relate directly to the damage it will inflict. Lower category storms (and
even tropical storms) can cause substantial damage depending on what other weather features they interact with, where
they strike, and how slow they move.
Anatomy of a Hurricane
Typical hurricanes are about 300 miles wide although they can vary considerably in size.
The eye at a hurricane's center is a relatively calm, clear area approximately 20-40 miles across.
The eyewall surrounding the eye is composed of dense clouds that contain the highest winds in the storm.
The storm's outer rainbands (often with hurricane or tropical storm-force winds) are made up of dense bands of
thunderstorms ranging from a few miles to tens of miles wide and 50 to 300 miles long.
Hurricane-force winds can extend outward to about 25 miles in a small hurricane and to more than 150 miles for a large
one. Tropical storm-force winds can stretch out as far as 300 miles from the center of a large hurricane.
Frequently, the right side of a hurricane is the most dangerous in terms of storm surge, winds, and tornadoes.
A hurricane's speed and path depend on complex ocean and atmospheric interactions, including the presence or absence
of other weather patterns. This complexity of the flow makes it very difficult to predict the speed and direction of a hurricane.
Do not focus on the eye or the track–hurricanes are immense systems that can move in complex patterns that are difficult
to predict. Be prepared for changes in size, intensity, speed, and direction.

The estimated value of the expression is π which is approximately equal to the number 3.14.
What is simplification?Simplification is to make something easier to do or understand and to make something less complicated.
The expression is given below.
[tex]\Rightarrow \dfrac{5\sqrt2 \pi - 4\sqrt2 \pi}{\sqrt2}[/tex]
Taking √2and π common, then we have
[tex]\rightarrow \dfrac{(5 - 4)\sqrt2 \pi}{\sqrt2}\\\\\\\rightarrow \dfrac{\sqrt2 \pi}{\sqrt2}\\\\\\\rightarrow \pi \approx 3.14[/tex]
The value of the expression is 3.14.
