Answer:
The possible number of miles you run is no more than 24.6 miles.
Step-by-step explanation:
Consider the provided information.
It is given that you run no faster than 8.2 miles per hour.
That means the maximum speed is less than or equal to 8.2 miles per hour.
This can be written as:
S≤8.2
We need to determine the inequality for possible numbers of miles you run.
[tex]Distance=Speed \times time[/tex]
We know time is 3 hr and S≤8.2.
Thus, the required inequity is:
[tex]D \leq 8.2\times 3[/tex]
[tex]D \leq 24.6[/tex]
Hence, the possible number of miles you run is no more than 24.6 miles.
In case you run for 3 hours at a speed no faster than 8.2 miles per hour. an inequality that represents the possible numbers of miles you run is d ≤ 24.6
What is the inequality?An inequality in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way. The majority of the time, size comparisons between two numbers on the number line are made.
The equation can be written as (Distance ≤ Speed * Time)
d ≤ (8.2 * 3 )
d ≤ 24.6 miles
d ≤ 24.6

a. 6,000 ft2
b. 2,000ft2
c. 640 ft2
d. 240 ft2
Answer:
Correct option is:
a. 6,000 ft²
Step-by-step explanation:
A pavement is 20 ft wide and 100 yd long
1 yd= 3 ft
100 yd = 300 ft
we have to find the area of pavement
Area= Length × Width
= 300 ft × 20 ft
= 6000 ft²

if you know two points on a line, how can you find the right the rate of change of the variables being graphed?
You divide the difference in y-coordinates by the diffrence in x-coordinates. Or whatever the variables are.
Lets say the coordinates of the two points are (a,b) and (c,d). Then:
Rate of change is "rise/run" = (b - d)/(c - a) = (d - b)/(a - c)
What is the slope of the perpendicular line x-2y=12
Hey there!!
Slope-intercept form :
y = mx + b
m is the slope and b is the y-intercept.
Given equation :
x - 2y = 12
We will have to isolate the y.
... x - 2y = 12
... -2y = x - 12
... y = ( x - 12 ) / -2
... y = x / - 2 + 6
Hence, the slope is -1/2

given -2(x + 1) = 5x + 4 - x ( distribute left side )
-2x - 2 = 4x + 4 ( simplifying both sides )
subtract 4x from both sides
- 6x - 2 = 4 ( add 2 to both sides )
- 6x = 6 ( variable by itself on left side )
divide both sides by - 6
x = [tex]\frac{6}{-6}[/tex] = - 1
as a check, substitute x = - 1 into the equation and if both sides are equal then it is the solution.
left side = - 2(-1 + 1 ) = - 2 × 0 = 0
right side = (5 × - 1) + 4 - (- 1) - 5 + 4 + 1 = 0
hence x = - 1 is the solution
what is 22 + 5d = -8(7d-4)
22+5d=-8x7d=56d+ -8x-4=32
22+5d=-56d+32
22+32=54 and -56d+5d=-51d
The answer would be 51d+54
Remark
The steps are the same usually. Remove the brackets and collect like terms on each side of the equal sign.
Solution
22+5d = -8(7d - 4) Remove the brackets.
22+5d = -56d + 32 Notice the sign change on 32. 2 minus quantities = a plus when multiplied. Add 56d to both sides.
22 + 5d + 56d = - 56d + 56d + 32
22 + 61d = 32 Subtract 22 from both sides.
61d = 32 - 22
61d = 10 Divide by 51
d = 10/61
d = 0.1639 Answer
Check
LHS
22 + 5*0.1639 = 22.8197
RHS
-8(7*0.1639 - 4)
-8(1.1473 - 4)

Ruben has 6 new books for his collection. This increases his collection by 12%? How many books does he have now?
Ruben has 6 new books for his collection. This increases his collection by 12%
Let x be the number of books Ruben has before 6 new books added
x + 12% of x = x+6
x + 0.12x = x+6
1.12 x = x+6
Subtract x on both sides
0.12x = 6
Divide by 0.12
x = 50
6 new books are added for his collection
So 50 + 6 = 56
He have 56 books now.

Which equation correctly applies the distributive property?
A. −1.2⋅0.57⋅0.5=−1.2⋅0.5⋅0.57
B. −2.5⋅(4⋅1.045)=(−2.5⋅4)⋅1.045
C. (0.5⋅0.5)+(0.5⋅0.3)+(0.5⋅0.2)=0.5⋅(0.5+0.3+0.2)
D. 50+1.015=(50⋅1)+(50⋅0.01)+(50⋅0.005)
The answer is choice C
On the left side we have something in the form a*b+a*c+a*d
On the right side we have something in the form a*(b+c+d)
All together, we have a*b+a*c+a*d = a*(b+c+d), where the letters a,b,c,d are to be replaced with the proper values (0.5, 0.5, 0.3, and 0.2 in that exact order).
The idea of distribution is to multiply the outer value 0.5 by each of the values inside the parenthesis (0.5, 0.3, and 0.2) and add up the products.
Equation C and D that is (0.5⋅0.5)+(0.5⋅0.3)+(0.5⋅0.2)=0.5⋅(0.5+0.3+0.2) and 0+1.015=(50⋅1)+(50⋅0.01)+(50⋅0.005) applies the distributive property correctly as defined "multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together".
What is distributive property?The distributive law, which states that in elementary algebra, equality is always true, is generalized by the distributive property of binary operations. For instance, in basic mathematics, one has to According to one, addition is distributed more evenly than multiplication. In order to quickly solve expressions, a number is distributed among the numbers in the brackets. When using the distributive property of multiplication, for instance, to resolve the expression 4(2 + 4), we would do so as follows: 4(2 + 4) = (4 × 2) + (4 × 4) = 8 + 16 = 24.
The distributive property states,
A × (B + C) = AB + AC
for equation C
(0.5⋅0.5)+(0.5⋅0.3)+(0.5⋅0.2)=0.5⋅(0.5+0.3+0.2)
for equation D,
50+1.015=(50⋅1)+(50⋅0.01)+(50⋅0.005)
According to the definition of the distributive property, which states that "multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together," Equations C and D, which are correctly applied that is (0.5⋅0.5)+(0.5⋅0.3)+(0.5⋅0.2)=0.5⋅(0.5+0.3+0.2) and 50+1.015=(50⋅1)+(50⋅0.01)+(50⋅0.005).

Graph the slow intercept equation: y=2/3x-2
Remark
The slope intercept graph needs a table like the one provided by the graph shown below.
A sample calculation would look like this
y = (2/3)x - 2 Let x = 6 (which is not plotted on the graph).
y = 2/3 * 6 - 2 The 3 will divide into the 6 two times
y = 4 - 2
y = 2
So you would plot this as (6,2)

Ram is twice as old as Sheeta. Five years ago his age was three times the age of Sheeta. Then the age of Sheeta is
Final answer:
Using the information that Ram is twice as old as Sheeta and that five years ago his age was three times the age of Sheeta, we solve the equation 2S - 5 = 3(S - 5) to find that Sheeta's current age is 10 years old.
Explanation:
The question involves creating equations based on the given information to solve for Sheeta's age. Let's denote Sheeta's age as 'S' and Ram's age as '2S' since Ram is twice as old as Sheeta. According to the second statement, five years ago Ram's age was three times Sheeta's age at that time. Therefore, we can write the equation as 2S - 5 = 3(S - 5).
Solving the equation step-by-step:
This simplifies to -S = -10
Hence, Sheeta's current age is 10 years old.

Evaluate the expression –0.4(3x – 2) + for x = 4
The expression evaluates to -4 when x equals 4.
To evaluate the expression –0.4(3x – 2) + for [tex]\( x = 4 \)[/tex], follow these steps:
1. Substitute the value of [tex]\( x \)[/tex] into the expression.
2. Perform the arithmetic operations according to the order of operations (PEMDAS/BODMAS).
Here's the step-by-step calculation:
Given expression: [tex]\(-0.4(3x - 2) +\)[/tex]
Substitute [tex]\( x = 4 \)[/tex]:
[tex]\(-0.4(3(4) - 2) +\)[/tex]
Now, simplify inside the parentheses first:
[tex]\(-0.4(12 - 2) +\)[/tex]
[tex]\(-0.4(10) +\)[/tex]
Next, multiply [tex]\(-0.4\)[/tex] by [tex]\( 10 \)[/tex]:
[tex]\(-4 +\)[/tex]
Finally, there's no more to compute since there's no other term. So the result is:
[tex]\(-4\)[/tex]
Therefore, the value of the expression [tex]\(-0.4(3x - 2)\)[/tex] when [tex]\( x = 4 \)[/tex] is [tex]\( -4 \)[/tex].
What is the density of a material that has a mass of 2,500 grams and volume of 500 cubic centimeter, in grams per cubic centimeter
Answer:
Density of the material is 5 grams per cubic centimeter.
Step-by-step explanation:
The answer is required to be given in grams per cubic centimeter.
So we should first convert the values to match the units.
Mass is given as 2500 grams so we don't need to change the units.
Volume is given in cubic centimeters. So we don't need to change the units.
Density = [ Mass of the material / Volume of the Solvent]
=2500 grams / 500 cubic centimeters
=5 grams per cubic centimeter
