Answer:
10). Proportional
11). Not proportional
Step-by-step explanation:
10) Let the relation between time (t) and heart beats (b) is proportional,
h ∝ t
h = kt
here, k = proportionality constant
Since, the graph of the equation is passing through a point a (4, 6),
6 = 4k
k = [tex]\frac{6}{4}[/tex]
k = 1.5
So the equation will be,
h = 1.5t
Since, all the points (6, 9), (10, 15)and (12, 18) follow the same relation represented by the equation, relationship is proportional.
11). Let the relationship shown by the table is proportional,
y ∝ x
y = kx [Here, k = proportionality constant]
k = [tex]\frac{y}{x}[/tex]
This constant should be same for all points given in the table.
For (4, 25),
k = [tex]\frac{25}{4}[/tex]
For (0, 5),
k = [tex]\frac{5}{0}[/tex]
This shows 'k' is not same for all points.
Therefore, relationship between x and y is not proportional.

If p < 0 and (2r – 6)2 = 64, what is the value of r?
Answers
Answer:
19
Step-by-step explanation:
The equation can also be written as:
(2r-6)(2)=64
4r-12=64
4r=76
r=19
There is no value of P in the equation so perhaps you wrote it wrong. But, if the equation looks like what you inserted, than r is 19.
1. If FG is perpendicular to AC and angle DAE = 35º, what is angle DEA?
Answers
Explanation:
If FG is perpendicular to AC, therefore angle ADE is 90 degrees.
It is given that angle DAE is 35 degrees,
so,
let’s say DEA is x.
all angles in a triangle always are 180 degrees.
35+90+x= 180
x=180-35-90
x= 55
Hope it’s clear! :):)

Sydney has $150 in her bank account. She buys a bike for $200. What is Sydney's account balance now?
Answers
Answer:
Sydney has -50 dollars in her account.
Step-by-step explanation:
If Sydney had $150 in her bank account. Then, she bought a bike for $200. To know her current bank account balance, than we must subtract $200 from $150.
150 - 200 = -50 dollars
This question doesn't really make sense though, since you can't buy something that you don't have enough money to buy.
Either way, I hope this helps! :D

If angle 1 is 108° and angle 4 is 95°, then what is the measure of angle 6? Explain your answer.
Answers
Answer:
23
Step-by-step explanation:
since the total of the interior angles of a triangle is always 180,
you will need to be able to find angles 3 and 4. by doing so, you need to notice that 1, 2, 3, and 4 make a straight line, also 180.
so you need to first do 180-108=72 << angle 2
180-95= 85 << angle 3
72+ 85= 157
and last, you subtract 157 from the total of 180 = 23

Carson and Avery work at a furniture store. Carson is paid $185 per week plus 1.5% of his total sales in dollars, xx, which can be represented by g(x)=185+0.015xg(x)=185+0.015x. Avery is paid $1 per week plus 5.5% of her total sales in dollars, xx, which can be represented by f(x)=1+0.055xf(x)=1+0.055x. Determine the value of xx, in dollars, that will make their weekly pay the same.
Answers
Answer:
$4,600
Step-by-step explanation:
Carson:
g(x) = 185 + 0.015x
Avery:
f(x) = 1 + 0.055x
Determine the value of x, in dollars, that will make their weekly pay the same.
Equate both functions
Carson = Avery
185 + 0.015x = 1 + 0.055x
Collect like terms
185 - 1 = 0.055x - 0.015x
184 = 0.040x
Divide both sides by 0.040
x = 184 / 0.040
= 4,600
x = $4,600
The value of x, in dollars, that will make their weekly pay the same is $4,600

259 Students go on a field trip. There are 19 vehicles, some vans, and some buses. 7 students can fit in a van, and 25 students can fit in a bus. how many buses were there? how many vans were there?
Answers
Answer:
7 buses and 12 vans
Step-by-step explanation:
This is the answer because:
1) Since there are 25 students in a bus, we multiply 7 and 25:
7 x 25 = 175
2) Then, we multiply 12 and 7 together since there are 7 students in each van:
12 x 7 = 84
3) Finally, to check our answer, we just have to add 175 and 84 together to know if this is correct or not:
175 + 84 = 259
Therefore, the answer is 7 buses and 12 vans.
Hope this helps! :D
The number of buses are 9 and the number of vans are 10.
What is a linear system of equations?A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.
Given that, 259 Students go on a field trip.
There are 19 vehicles, some vans, and some buses.
Let number of vans be v and the number of buses be b.
So, v+b=19 ---------(I)
7 students can fit in a van, and 25 students can fit in a bus.
Then, 7v+25b=295 ---------(II)
From equation (I), we have v=19-b
Substitute v=19-b in equation (II), we get
7(19-b)+25b=295
133-7b+25b=295
18b=295-133
18b=162
b=9
Now, v+b=19
v=10
Therefore, the number of buses are 9 and the number of vans are 10.
