While playing basketball, Jada’s heart rate goes up to 140 beats per minute. While jogging, her heart beats 40 times in 15 seconds. Assuming her heart beats at a constant rate while jogging, which of these activities resulted in a higher heart rate? Explain your reasoning.
Answer:
Basketball
^^
Step-by-step explanation:
10 x 6 = 60 (there are 60 seconds in a minute)
25 x 6 = 150

The table represents a proportional relationship between the number of hours it shows h, and the number of inches of snow, s on the ground. Find the constant of proportionality
The constant of proportionality is.
The constant of proportionality is 4, and the relationship is given by s = 4h.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A variable can either be dependent or independent. A dependent variable depend on other variable while an independent variable does not depend on other variables.
Let h represent the number of hours and s represent the number of inches of snow on the ground. Since both variables are proportional, hence:
s = hk; where k is the constant of proportionality
Let us assume in the table, when h = 1, s = 4 hence:
s = hk
4 = k(1)
k = 3
s = 4h
The constant of proportionality is 4, and the relationship is given by s = 4h.

Ramon places a mirror on the ground 45 ft from the base of a geyser. He walks backwards until he can see the top of the geyser in the middle of the mirror. at that point, Ramon eyes are 6 ft above the ground and he is 7.5 ft from the mirror. Use similar triangles to find the geyser
Answer:
36 ft
Step-by-step explanation:
6/x=7.5/45
270=7.5x
x=36
In this exercise we have to have knowledge of triangles, so we can use the theory of similar triangles to find the value of X, like:
[tex]36 ft[/tex]
To use similar triangle theory, we have to make a rule of 3, that is:
[tex]6/x=7.5/45\\270=7.5x\\x=36[/tex]

A boat on a river travels downstream between two points, 90 mi apart, in 1 h. The return trip against the current takes 2 1 2 h. What is the boat's speed (in still water)?
Answer:
A)63miles per hour.
B)27 miles per hour
Step-by-step explanation:
HERE IS THE COMPLETE QUESTION
boat on a river travels downstream between two points, 90 mi apart, in 1 h. The return trip against the current takes 2 1 2 h. What is the boat's speed (in still water)??b) How fast does the current in the river flow?
Let the speed of boat in still water = V(boat)
speed of current=V(current)
To calculate speed of boat downstream, we add speed of boat in still water and speed of current. This can be expressed as
[V(boat) +V(current)]
It was stated that it takes 1hour for the
boat to travels between two points of 90 mi apart downstream.
To calculate speed of boat against current, we will substact speed of current from speed of boat in still water. This can be expressed as
[V(boat) - V(current)]
and it was stated that it takes 2 1/2 for return trip against the Current
But we know but Speed= distance/time
Then if we input the stated values we have
V(boat) + V(current)]= 90/1 ---------eqn(1)
V(boat) - V(current) = 90/2.5----------eqn(2)
Adding the equations we have
V(boat) + V(current) + [V(boat) - V(current)]= 90/2.5 + 90/1
V(boat) + V(current) + V(boat) - V(current)]=90+36
2V(boat)= 126
V(boat)=63miles per hour.
Hence, Therefore, the speed of boat in still water is 63 miles per hour.
?b) How fast does the current in the river flow?
the speed of the current in the river, we can be calculated if we input V(boat)=63miles per hour. Into eqn(1)
V(boat) + V(current)]= 90/1
63+V(current)=90
V(current)= 27 miles per hour
Hence,Therefore, the speed of current is 27 miles per hour.

A median of a triangle always bisects the angle of the triangle that it intersects. true or false
Answer: True
Step-by-step explanation: Every triangle has exactly three medians, one from each vertex, and they all intersect each other at the triangle's centroid. In the case of isosceles and equilateral triangles, a median bisects any angle at a vertex whose two adjacent sides are equal in length. The concept of a median extends to tetrahedra.
Answer:
True

Given CAD is a right angle and AB is bisecting CAD and if DAB=(7x-4) find X
Answer:
x = 7
Step-by-step explanation:
∠CAD is a right angle, right angles has 90° measurement.
m∠DAB = 7x - 4 AB bisects ∠CAD this means it divides the angle into two equal parts.
So it's safe to write the following equation:
7x - 4 = 45 (half of 90°)
add 4 to bot sides
7x = 49 divide both sides by 7
x = 7
