47 miles
Step-by-step explanation:
since 2 hours is 94 miles and 4 hours is 238 miles, you can take the 94 and divide by 2 to get how many miles for 1 hour.
The average rate of change will be;
⇒ 72 miles per hour
What is Division method?
Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
George is driving his car. At the end of 2 hours he has driven 94 miles, and at the end of 4 hours he has driven 238 miles.
Now,
Since, We know that;
⇒ Speed = Distance / Time
Hence, We can formulate;
⇒ The average rate of change = (238 - 94) / (4 - 2)
= 144 / 2
= 72
Thus, The average rate of change will be;
⇒ 72 miles per hour

Answer:
Answer the first choice.
Step-by-step explanation:
Given
Points (-2,6) and (0,2)
y2 = 6
y1 = 2

Kellan’s lemonade recipe uses 4 scoops of lemonade powder for every 2.5 cups of water. Kellan uses 10 scoops of lemonade powder to make a batch of lemonade. How much water should he use?
Answer:
6.25 cups of water
Step-by-step explanation:
So I first write out the rates: 4:2.5 and also 10:?
So let's find out how the scoops changed, as in how did you get 4 to become 10 so you can do the same thing to 2.5 and get ?.
To go from 4 to 10 you MULTIPLY/DIVIDE. DON'T ADD OR SUBTRACT. 10 divided by 4 (to see what you multiplied by) is 2.5.
So we multiplied 4 by 2.5 to get 10. So if we multiply 2.5 by 2.5 we get 6.25.
So 4:2.5 = 10:6.25
?=6.25

The two latches make known the fact that this is an isosceles triangle. Here, x is the base angle. There are two base angles in isosceles triangles. Base angles have the same measure. This explains the reason for 2x in the equation below.
Here is the set up:
x + x + 32 = 180
2x + 32 = 180
2x = 180 - 32
2x = 148
x = 148/2
x = 74
The value of x is 74 degrees.

Solve 5x+2=20
Answer:
x = 18/5
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define equation
5x + 2 = 20
Step 2: Solve for x
Subtract 2 on both sides: 5x = 18Divide 5 on both sides: x = 18/5Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 5(18/5) + 2 = 20Multiply: 18 + 2 = 20Add: 20 = 20Here we see that 20 does indeed equal 20.
∴ x = 18/5 is a solution to the equation.

Suppose you find a plant that has a woody stem and is taller than you. Would you classify the plant as vascular or non-vascular. Explain. *
-science
Answer:
The main difference between a vascular and a non-vascular plant is that a vascular plant has vessels that can carry food and water to all the other parts of the plant. the arrangements of the cell in a non-vascular plant is also a lot simpler.
Step-by-step explanation:
I would classify the plant as vascular because vascular plants tend to be really tall and large in comparison to non-vascular plants.

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.
A linear equation is an algebraic equation of the form y=mx+b involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept. Occasionally, the above is called a "linear equation of two variables," where y and x are the variables.
Given that
Total amount of solution = 90
total amount of salt = 15 % of 90
= [tex]90 \times \frac{15}{100}[/tex]
= 13.5
Now removed X from the solution
Then, remaining solution is 90 - X
Percentage of salt in the remaining solution [tex]= \frac{salt}{remaining solution}[/tex]
Given that , % of salt in the remaining solution is equal to 25% then, Percentage of salt in the remaining solution
⇒ [tex]\frac{salt}{remaining solution}[/tex] = 25%
⇒ [tex]\frac{13.5}{90 - X} = \frac{25}{100}[/tex]
⇒1350 = 2250 - 25 x
⇒ 25 x = 2250 - 1350
⇒ 25 x = 900
⇒ x = [tex]\frac{900}{25}[/tex]
⇒ x =36

max picks two different cards without replacement from a standard $52$-card deck. what is the probability that the cards are of different suits?
The probability that cards are from different suits is [tex]\frac{39}{51}[/tex]
Probability of an event E represented by P(E) can be defined as (The number of favorable outcomes )/(Total number of outcomes).
There are 4 suits hearts, diamonds, club and spade in a standard deck of 52 cards.
Each of them has 13 cards each .
So when we pick first card from a single suit
we can pick it in 13 ways , now 12 cards are left.
We can pick the 2nd card from the same suit in 12 different ways .
So to pick 2 cards from a single suit we have 13x12 ways.
to pick 2 card from 4 suits = 4x13x12=624 ways
Total ways of choosing 2 cards from the pack of 52 cards is 52 X 51 =2652
probability that the cards are of same suits=[tex]\frac{624}{2652} =\frac{12}{51}[/tex]

what is equation of straight line shown below give answer in form y=mx+c where m and c are intervenes or fractions in simplest form
The equation of the straight line is y = 2x + 6.
What is an equation of a line?An equation of a line is a mathematical expression that describes the relationship between the x and y coordinates of the points on the line. There are several different forms of the equation of a line, but the most commonly used is the slope-intercept form:
y = mx + b
where m is the slope of the line and b is the y-intercept, which is the point where the line crosses the y-axis.
We have,
To find the equation of the straight line passing through the points (-3, 0) and (0, 6), we can use the slope-intercept form of a linear equation, which is:
y = mx + c
where m is the slope of the line and c is the y-intercept.
We can first find the slope of the line using the formula:
[tex]m = (y_2 - y_1) / (x_2 - x_1)[/tex]
[tex]where ~(x_1, y_1) = (-3, 0) ~and ~(x_2, y_2) = (0, 6):[/tex]
So,
m = (6 - 0) / (0 - (-3)) = 6/3 = 2
Now we can substitute the slope and one of the points into the slope-intercept form to find the y-intercept:
y = mx + c
0 = 2(-3) + c
0 = -6 + c
c = 6
Therefore,
The equation of the straight line is y = 2x + 6.

The equations are;
4(2x + 5) = 3(2x + 8)
x = 2
Perimeter of each shape is 36
Step-by-step explanation:
Mathematically;
The perimeter of a square is 4L
while the perimeter of an equilateral triangle is 3L
where L represents the lengths of the sides
Mathematically, from what we have in the question, since the perimeter are equal;
4(2x + 5) = 3(2x + 8)
8x + 20 = 6x + 24
8x-6x = 24-20
2x = 4
x = 4/2
x = 2
The side of the square will measure;
2(2) + 5 = 9
Its perimeter is 4(9) = 36
The side of the triangle will measure
2(2) + 8 = 12
Its perimeter will be 3(12) = 36

Step-by-step explanation:
f(x)=a(1+r)^{x}
f(x)=exponential growth function
a=initial amount
r=growth rate
{x}=number of time intervals
so let x=years
start amount is 1,500
1,500(1+r)^5=2100
(r+1)^5= 7 /5
((r+1)5) ^1 /5 =( 7 /5 ) ^1 /5
r=0.06961
