Explanation of how to simplify expressions with exponents by subtracting exponents. The answer shows the equivalence of 5×2/3 and 10×1/3.
The expression [tex]( \frac{5 \times 2}{3} )[/tex] equals [tex]( \frac{10}{3} )[/tex]. Let's break it down:
[tex]\( \frac{5 \times 2}{3} \)[/tex] means you multiply 5 and 2 first, which gives you 10, then you divide by 3, resulting in [tex]\( \frac{10}{3} \)[/tex].
However, if you're asking why [tex]\( \frac{5 \times 2}{3} \)[/tex] and [tex]\( 10 \times \frac{1}{3} \)[/tex] are equal, it's because multiplication is distributive over division.
In other words, [tex]\( a \times \frac{b}{c} = \frac{a \times b}{c} \)[/tex].
So, [tex]\( 10 \times \frac{1}{3} \)[/tex] can be written as [tex]\( \frac{10 \times 1}{3} \)[/tex], which simplifies to [tex]\( \frac{10}{3} \)[/tex], the same as [tex]\( \frac{5 \times 2}{3} \)[/tex].

Cristiano is rolling a number cube. What is the probability of rolling a , or
a 6 followed by a 3 or a 4?
The probability of rolling a 6 followed by either a 3 or a 4 on a six-sided die is calculated by multiplying the probability of rolling a 6 (1/6) by the probability of then rolling either a 3 or a 4 (1/3), resulting in a combined probability of 1/18.
The question posed is about the probability of rolling a 6 followed by either a 3 or a 4 on a standard six-sided die. To find this, we first consider that the probability of rolling a specific number, such as a 6, on a six-sided die is 1/6. This is because there are 6 outcomes and only one of those outcomes is the desired number.
When rolling for the second number, which could either be a 3 or a 4, we have two desired outcomes out of the six possible outcomes on the die. Therefore, the probability of rolling either a 3 or a 4 is 2/6, which simplifies to 1/3.
To find the overall probability of rolling a 6 followed by either a 3 or a 4, we multiply the two probabilities together: (1/6) * (1/3) = 1/18. Therefore, the probability of this event occurring is 1/18.

A line has a slope of Negative three-fourths and passes through the point (–5, 4). Which is the equation of the line?
y = negative three-fourths x + one-fourth
y = negative three-fourths x + 4
y = negative three-fourths x minus 2
y = negative three-fourths x minus one-fourth
The equation of the line is [tex]y=-\frac{3}{4}x+\frac{1}{4}[/tex]
Step-by-step explanation:
The equation of a line can be written using the following form
[tex]y-y_0 = m(x-x_0)[/tex]
where
m is the slope of the line
[tex](x_0,y_0)[/tex] are the coordinates of a point lying on the line
For the line in this problem, we know that:
[tex]m=-\frac{3}{4}[/tex] is the slope
[tex](x_0,y_0)=(-5,4)[/tex] are the coordinates of the point
Therefore, substituting into the equation,
[tex]y-4=-\frac{3}{4}(x-(-5))[/tex]
And re-arranging the equation we get:
[tex]y-4=-\frac{3}{4}(x+5)\\y-4=-\frac{3}{4}x-\frac{15}{4}\\y=-\frac{3}{4}x+(4-\frac{15}{4})\\y=-\frac{3}{4}x+\frac{1}{4}[/tex]

Together, teammates Pedro and Ricky got 2681 base hits last season. Pedro had 283 more hits than Ricky. How many hits did each player have
Answer:
Ricky had 1199 hits.
Pedro had 1482 hits.
Step-by-step explanation:
State your variables
let "p" be the number of Pedro's base hits
let "r" be the number of Ricky's base hits
Create equations using information from the problem
p + r = 2681 [1]
p = r + 283 [2]
Substitute equation [2] in equation [1] replacing 'p'
p + r = 2681
r + 283 + r = 2681
Combine like terms to simplify
2r + 283 = 2681
Isolate '"r" to solve for Ricky's base hits.
2r + 283 - 283 = 2681 - 283 Subtract 283 on both sides
2r = 2398
2r/2 = 2398/2 Divide both sides by 2
r = 1199 Number of Ricky's hits
Substitute r = 1199 into any equation to find "p". I will use [2].
p = r + 283
p = 1199 + 283 Add
p = 1482 Number of Pedro's hits
Therefore Ricky had 1199 hits and Pedro had 1482 hits.
Ricky had 1199 hits and Pedro had 1482 hits.
Explanation:To solve this problem, we can set up a system of equations. Let x represent the number of hits Ricky had. Pedro had 283 more hits, so Pedro's number of hits would be x + 283.
Together, their hits add up to 2681, so we can write the equation:
x + (x + 283) = 2681
Combining like terms:
2x + 283 = 2681
Subtracting 283 from both sides:
2x = 2398
Dividing both sides by 2:
x = 1199
Ricky had 1199 hits and Pedro had x + 283 = 1199 + 283 = 1482 hits.

Madison is riding her horse around the outside of a circular arena.she knows 14 laps is 1/2 a mile what is the diameter of the arena
Answer:
The diameter of the arena is 18.3 meters.
Step-by-step explanation:
As, 14 laps = [tex]\frac{1}{2}[/tex] mile
so, 1 lap = [tex]\frac{1}{28}[/tex] mile ( ∵14 × 2 = 28)
For the horse completing one lap it completes the perimeter of the circle.
perimeter (P) = [tex]\frac{1}{28}[/tex] mile
let diameter of that circle be represented as d,
P= [tex]\pi[/tex] × d
or, [tex]\frac{1}{28}[/tex] = [tex]\pi[/tex] × d
or, d= [tex]\frac{1}{28\pi }[/tex]
∴ d= 18.3 meters.
The diameter of the arena is 18.3 meters.

45 %of population of a town is female . what's the population of male if total population is 54320
Answer:29876
Step-by-step explanation:
Entire population is 100%
Male is 100%-45%
55%x54320=29876
Answer:
29,876 males
Step-by-step explanation:
If 45% of 54320 population is female. The population of male is calculated below.
The total population is 100% and female is 45%. Thus: 100% - 45% = 55%.
Percentage of male population is 55%. Hence, 55% of 54320 is calculated thus:
[tex] \frac{55}{100} \times 54320[/tex]
[tex] = 0.55 \times 54320[/tex]
[tex] = 29876[/tex]
Therefore, population of male if total population is 54320 is 29,876.
Check,
Female population percentage + male population percentage:
45% + 55% = 100%
24,444 + 29,876 = 54,320
The largest possible circle is cut out of a square whose side length is 8 feet. What will be the approximate area, in square feet, of the remaining board? ( A=3.14r2)

Answer:
4^-2
Step-by-step explanation:
The rules of exponents tell you ...
(a^b)(a^c) = a^(b+c)
This means ...
(4^6)(4^-8) = 4^(6-8) = 4^-2
To simplify the expression (4^6)(4^-8), add the exponents and rewrite the expression as 4^(-2). Then, use the rule that states any number raised to the power of -1 is the reciprocal of that number to rewrite 4^-2 as 1/(4^2) which equals 1/16.
Explanation:To simplify the expression (4^6)(4^-8), we can use the rule that states when you multiply two powers with the same base, you add their exponents. In this case, 4^6 multiplied by 4^-8 will be equal to 4^(6 + (-8)). Simplifying the exponent, we have 4^(-2). Since any number raised to the power of -1 is the reciprocal of that number, we can rewrite 4^-2 as 1/(4^2) which is equal to 1/16.

-4
-1

4
Answer:
y-intercept is 1
Step-by-step explanation:
We need to find the equation of the line first.
GradientThe gradient is found using the formula:
[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
[tex]m=\frac{-1-2}{8--4}[/tex]
[tex]m=-\frac{1}{4}[/tex]
So the equation is y = [tex]-\frac{1}{4}[/tex]x + c
Finding cTo find c we need to substitute the value of x and y into the equation:
-1 = [tex]-\frac{8}{4}[/tex] + c
-1 = -2 + c
1 = c
And c is the y-intercept so it is 1
Answer:
y- intercept = 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (8, - 1) and (x₂, y₂ ) = (- 4, 2)
m = [tex]\frac{2+1}{-4-8}[/tex] = [tex]\frac{3}{-12}[/tex] = - [tex]\frac{1}{4}[/tex], thus
y = - [tex]\frac{1}{4}[/tex] x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (8, - 1), then
- 1 = - 2 + c ⇒ - 1 + 2 = 1 ← y- intercept
