Answer:
They did not run at the same speed. Calculation of their speed shows that Jada was running at a higher speed.
Step-by-step explanation:
Let's first calculate the speed of each person using the units provided so that we do not complicate the question.
speed = distance covered/time taken
Andre's speed = 2 km/15 min = 0.133 km/min
Jada's speed = 3km/20 min = 0.15 km/min
Clearly we can see that Jada was running at a higher speed than Andre. The question says they were running at constant speed not equal speed. That just means each person maintained their speed, they did not get faster or slower.
If two angles of a triangle each measure 70°, the triangle is

Answer:
An isosceles triangle
Step-by-step explanation:
An isosceles triangle has 2 of the same sides and angles.
Plz give me brainliest.
The given triangle with two angels is 70° and will be the isosceles triangle.
What is the isosceles triangle?
A summation, also abbreviated as a sum, is the consequence of adding two or more numbers or quantities. Usually are always an equivalent number of terms in a summation.
There could be only two terms, and there could be one hundred, thousand. There seem to be summations with an infinite number of representatives.
On another hand, an isosceles triangle is a triangle in which any two sides or angles will be the same.
Hence given that the triangle has
Angle first = 70°
Angle second = 70° since there are two angles same so there will also be two sides equal so it will be an isosceles triangle.

A sample denotes a smaller, controllable form of a larger cluster. It is a subset comprising of the characteristics of a bigger population. Samples are used in statistical experiments when the population under consideration is too large for the test to include all the members.
The sample size in this case = 10 + 23 + 28 + 14 = 75
Thus, the size of your sample is 75.

-34h>0
-34h/-34h>0/-34h
H<0
4. H(17)+H(27)=h(29)
H•17 +h(21)=h(29)
17h+h(21)=h(29)
H17 +h•(21)=h(29)
17h+h(21)=h(29)
combine it
17h+21h=h(29)
38=h(29)
38h=h•29
38h=h29
38h-29h=h29-29h

Graph the equation y=x^2-8x+7y=x on the accompanying set of axes. You must plot 5 points including the roots and the vertex.
what points do i need to plot on the graph from this equation please hurry brainlest for whoever can help and 20 points
Answer: If you're plotting 1 equation (y=x^2-8x):
(-4,16) Vertex
(0,0) root
(8,0) root
If plotting both (y=x^2-8x) & (7y=x):
(-4,16) Vertex
(0,0) root
(8,0) root
(7,1) point on line
(-7, -1) point on line
Step-by-step explanation:
The vertex of the parabolic equation y = x² - 8x + 7 will be at (4, -9).
Now, Let the point (h, k) be the vertex of the parabola and a be the leading coefficient.
Then the equation of the parabola will be given as,
y = a(x - h)² + k
The equation is given below.
y = x² - 8x + 7
Convert the equation into a vertex form. Then we have
y = x² - 8x + 7
y = x² - 8x + 16 - 16 + 7
y = (x - 4)² - 9
Hence, The vertex of the parabolic equation y = x² - 8x + 7 will be at
(4, -9).
So, The graph is given below.

The distance Train A travels is represented by d = 80t, where d is the distance in kilometers
and t is the time in hours. The distance Train B travels at various times is shown in the
table. What is the rate of each train? Which train is going faster?
Time (hours) Distance (km)
2
190
4
380
5
475
The rate of Train A is 160|
km per hour.
The rate of Train Bis
km per hour.
Train (select)
is going faster.
Answer:
Train B is going faster than Train A
Step-by-step explanation:
The distance travelled by Train A, d = 80t
The distance travelled by Train B is given as follows;
Time (hours) [tex]{}[/tex] Distance (km)
2 [tex]{}[/tex] 190
4 [tex]{}[/tex] 380
5 [tex]{}[/tex] 475
Therefore, we have that the rate of change of Train B is given as follows;
(475 - 380)/(5 - 4) = 95 km/h
(475 - 190)/(5 - 2) = 95 km/h
The rate of change of Train B = 95 km/h
While the distance covered by Train A per 1 hour, t = 1 is given as follows
Distance covered in 1 hour for Train A, d = 80 × 1 = 80 kilometers
The rate of train A = Distance covered/(Time in which the distance was covered)
The rate of train of change A = 80 km/(1 hour) = 80 km/hour
The rate of train of change A = 80 km/h
Therefore, Train B is going faster than Train A.
