Keenan hiked 15 times as far as Margot. How far did Keenan hike? the total number of miles be m
The Keenan hike is measured in m is [tex]\frac{15m}{16}[/tex]miles.
The given parameters;
Keenan and Margot hiked m miles altogether.
Let the distance Margot hiked = n
Then, the distance Keenan hiked = 15n
The combined distance both hiked: m = n + 15n
Calculating Margot's hiked distance in terms of m is as follows:
m = n + 15n
m = 16n
n=[tex]\frac{m}{16}[/tex]
The calculation for Keenan's hike in terms of miles is
= 15(n)
=15[tex]\frac{m}{16}[/tex]
=[tex]\frac{15m}{16}[/tex]
Thus, the distance hiked by Keenan in terms of m is [tex]\frac{15m}{16}[/tex]miles.

2 l2x+7l = 16
Please help me with this ASAP
Answer:
x = 1/2 and
x = -15/2
Step-by-step explanation:
First, get the absolute value alone on one side if the equation.
2 |2x + 7 | = 16
Divide both sides by 2.
| 2x + 7 | = 8
Once the absolute value sign is by itself, you will separate the equation into two separate equations.
2x+7=8 and 2x+7=-8
Solve these two equations separately and get two solutions.
2x + 7 = 8
Subtract 7.
2x = 1
Divide by 2.
x = 1/2 Here is one solution.
2x + 7 = -8
Subtract 7.
2x = -15
Divide by 2.
x = -15/2 Here is a second solution.
Answer:
x = - [tex]\frac{15}{2}[/tex] , x = [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
2 | 2x + 7 | = 16 ( divide both sides by 2 )
| 2x + 7 | = 8
the absolute value function always gives a positive result, but the expression inside can be positive or negative , that is
2x + 7 = 8 ( subtract 7 from both sides )
2x = 1 ( divide both sides by 2 )
x = [tex]\frac{1}{2}[/tex]
or
- (2x + 7) = 8
- 2x - 7 = 8 ( add 7 to both sides )
- 2x = 15 ( divide both sides by - 2 )
x = - [tex]\frac{15}{2}[/tex]
As a check
substitute these values into the left side and if equal to the right side then they are a solution
x = [tex]\frac{1}{2}[/tex]
2 | 2([tex]\frac{1}{2}[/tex] ) + 7 | = 2 | 1 + 7 | = 2 | 8 | = 16 = right side
x = - [tex]\frac{15}{2}[/tex]
2 | 2(- [tex]\frac{15}{2}[/tex] ) + 7 | = 2 | - 15 + 7 | = 2 | - 8 | = 2 | 8 | = 16 = right side
then x = - [tex]\frac{15}{2}[/tex] and x = [tex]\frac{1}{2}[/tex] are the solutions

The new flat screen television that Tracy bought has a diagonal length of 56 inch
With the information given we can calculate the diagonal length of the television using the Pythagorean theorem equation.

The tree was 210 cm tall.
Let 'h(t) ' models the height of the tree in centimeters and 't' denotes the number of years since Renata moved in.
Given, h(t) = 210 + 33t
This is a linear function in 't'.
This function says that in each year the tree grows 33 cm tall.
We need to find the height of the tree when Renata moved in.
When Renata moved in, the number of years, t = 0
Applying this into h(t) , we get,
h(t) = 210 + 33 x 0 = 210 cm
Therefore the tree was 210 cm tall when Renata moved in.

It is given that in the first week her savings were $8 less than 2/5 the price of the system which can be represented by equation
First week savings = (2/5)x -8
It is also given that in the second week, she saved 50 cents more than 1/2 the price of the system which can be represented by equation

Michael makes a model to show the distances between the Sun and the planets.
Earth is 1.50 x 10¹¹ m from the Sun. The distance on the model is 30 cm. What is the ratio of the lengths of the model to the actual distance?
Step-by-step explanation:
do 1.50 times 10 and the multiple by 30 to get the answer
The ratio of the lengths of the model to the actual distance is approximately 2 x 10⁻¹³.
To find the ratio of the lengths of the model to the actual distance, we need to compare the lengths in the same unit. Let's convert the actual distance between the Sun and Earth from meters to centimeters, so both values are in centimeters.
1 meter = 100 centimeters
Actual distance from the Sun to Earth = 1.50 x 10¹¹ meters
Actual distance from the Sun to Earth in centimeters = 1.50 x 10¹¹ meters * 100 centimeters/meter
Actual distance from the Sun to Earth in centimeters = 1.50 x 10¹¹ meters * 100 centimeters/meter = 1.50 x 10¹³ centimeters
Now, we can compare the lengths:
Length on the model = 30 centimeters
Actual distance from the Sun to Earth = 1.50 x 10¹³ centimeters
The ratio of the lengths of the model to the actual distance is:
Ratio = Length on the model / Actual distance from the Sun to Earth
Ratio = 30 centimeters / (1.50 x 10¹³ centimeters)
To simplify this ratio, let's express the actual distance in scientific notation:
1.50 x 10¹³ = 15 x 10¹² = 1.5 x 10¹³
Now, the ratio becomes:
Ratio = 30 centimeters / (1.5 x 10¹³ centimeters)
Now, notice that both values are in the same unit (centimeters). We can proceed with the division:
Ratio ≈ 0.0000000000002
Therefore, the ratio of the lengths of the model to the actual distance is approximately 2 x 10⁻¹³. This means that every 1 centimeter on the model represents approximately 2 x 10⁻¹³ centimeters in actual distance between the Sun and Earth.

The right answer is that there are four electrons.
What is an atomic number?The charge number of an atomic nucleus is the chemical element's atomic number, also known as the nuclear charge number.
For conventional nuclei, this is comparable to the proton number, or the number of protons found in the nucleus of each atom of that element.
Equal numbers of protons and electrons make up a neutral atom. This figure establishes the atom's atomic number.

The volleyball team ended up practicing for 1.2 hours on Friday.
The total number of hours the volleyball team practiced on Monday, Tuesday, Wednesday, and Thursday can be determined by adding the values given in the statement.
Therefore,
the total number of hours the team practiced on Monday, Tuesday, Wednesday, and Thursday=0.5 hours+1.3hours+2.2hours+0.8hours= 4.8 hours
Total number of hours the team practiced last week = 6 hours
The number of hours they practiced on Friday can be calculated by subtraction of the total number of hours of the week from the total number of hours on Monday, Tuesday, Wednesday, and Thursday.
