Andre ran 2 kilometers in 15 minutes and Jada ran 3 kilometers in 20 minutes. Both ran at a constant speed. Did they run the same rate? Explain or show your reasoning.
You might use:
-ratio tables
-double number lines
-unit rates
-Equivalent ratios
yeah
Answers
Answer:
no, Andre ran at a sperm of 8km/hr while jada ran at 9km/hr you can find that by Andre going 2km in 15 minutes which turns to hours by multiplying by 4/4 to get 8/60 which 60 minutes is 1 hour then jada multiply by 3/3 which would be 9/60

Solve for x: 3 (x - 3) + 8x = 5(2x + 1)
Answers
Answer:
x = 14
Step-by-step explanation:
3 (x - 3) + 8x = 5 (2x + 1)
FOIL: 3x - 9 + 8x = 10x +5
Move all the x terms to one side and all the constants to the other:
3x + 8x - 10x = 5 + 9
Combine like terms: x = 14

model of a soccer field shows 12 in by 24 in the scale is model is 1 in equals 4 yards Manny runs across the length of the soccer field five times how far did he run
Answers
Answer:
480 yds.
Step-by-step explanation:
Model is 12in X 24in
Scale is 1in = 4 yds
24 in is the length, so multiply the 24 and 4 to find length of the actual field.
24 *4 = 96 yds. Manny ran it 5 times, multiply 96 and 5. 96 * 5 = 480 yds.
what's the area of the shape .
Answers
Answer:
[tex]Area = 210m^2[/tex]
Step-by-step explanation:
The attached shape is a trapezium and the given dimensions are:
[tex]B_1 = 10m[/tex] -- Base 1
[tex]B_2 = 20m[/tex] --- Base 2
[tex]H = 14m[/tex] --- Height
Required
Calculate the area
The area is calculated as thus:
[tex]Area = \frac{1}{2}(B_1 + B_2) * H[/tex]
[tex]Area = \frac{1}{2}(10m + 20m) * 14m[/tex]
[tex]Area = \frac{1}{2}(30m) * 14m[/tex]
[tex]Area = 15m * 14m[/tex]
[tex]Area = 210m^2[/tex]
Find m\angle Am∠Am, angle, A.
Round to the nearest degree.
Answers
Answer:
m∠A = 106°
Step-by-step explanation:
All three sides of the triangle are given in the question.
To find the measure of included angle A between two sides we will apply cosine formula,
BC²= AB² + AC² - 2(AB)(AC)cosA
(13)² = (10)² + (6)² - 2(10)(6)cosA
169 = 100 + 36 - 120cosA
cosA = [tex]\frac{-169+136}{120}[/tex]
cosA = -0.275
A = [tex]\text{cos}^{-1}(-0.275)[/tex]
A = 105.96°
A ≈ 106°
Therefore, m∠A = 106° will be the answer.

If the values in the table below model a proportional relationship, what is the equation for the function?
Answers
Given:
The table represents a proportional relationship.
To find:
The equation of the function.
Solution:
If y is directly proportional to x, then
[tex]y\propto x[/tex]
[tex]y=kx[/tex] ...(i)
where, k is the constant of proportionality.
From the given table it is clear that the function passes through (2,1). So, the equation must be satisfied by the point (2,1).
Putting x=2 and y=1 in (i), we get
[tex]1=k(2)[/tex]
[tex]\dfrac{1}{2}=k[/tex]
Putting [tex]k=\dfrac{1}{2}[/tex], we get
[tex]y=\dfrac{1}{2}x[/tex]
Therefore, the correct option is A.
How can you tell if a graph is function or not
Answers
Answer:
If the vertical line intersects the graph in at most one point, then the given graph represents a function. If the vertical line intersects the graph in more than one point, then the given graph does not represent a function.
I HOPE IT HELPS
TAKE CARE
Step-by-step explanation:
Answer:
Step-by-step explanation:
For a graph to be a function, there must not be more than one element in the range for each element of the domain.
If x represents the doman, and y represents the range (as usual, in graphing) then each value on the the x-axis should not have more than one point in the graph on it, directly above it, or directly below it. Like if you had a point (5, 7) and also had point (5, -7), that is not a function. The x, 5, has more than one y-value paired with it.
Visually, any vertical line through the graph should not intersect the graph at more than one point. If it does, then the graph is not a function.
This is called the vertical line test.

What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
y = 2x - 3
Now, putting x=0
y= -3
and, x= 1
y= 2(1)-3
y = -1
and, x= 2
y=2 (2)- 3
y = 1
Hence, the coordinates of line is (0, -3), (1, -1) and (2, 1)

The probability that the selected student is a male is 0.466 or 47%.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
There are a total of 4+6+2+2=14 male students and
3+4+6+3=16 female students in the class.
The probability of selecting a male student at random is the number of male students divided by the total number of students
P(male) = number of male students / total number of students
P(male) = 14 / (14+16)
P(male) = 14 / 30
P(male) = 0.466
Therefore, the probability that the selected student is a male is 0.466 or 47%.
