Complete question :
Ryan is choosing between two exercise routines. In Routine #1, he burns 22 calories walking. He then runs at a rate that burns 10.5 calories per minute. In Routine #2, he burns 39 calories walking. He then runs at a rate that burns 6.25 calories per minute. For what amounts of time spent running will Routine #1 burn at most as many calories as Routine #2?
Answer:
4 minutes
Step-by-step explanation:
Given the following exercise routines :
Routine #1,
Walking : burns 22 calories walking. He then running : burns 10.5 calories per minute.
Routine #2,
Walking : burns 39 calories walking. He then running : burns 6.25 calories per minute.
Let number of tone spent running = t
Hence,
Routine 1 ; calories burned
22 + 10.5t
Routine 2 ; calories burned
39 + 6.25t
Equating the two equations :
22 + 10.5t = 39 + 6.25t
10.5t - 6.25t = 39 - 22
4.25t = 17
t = 17/4.25
t = 4

1. Cindy did an experiment. She started out with 700 bacteria cells. She found that the growth rate of the bacteria cells was 4.3%. Create an equation for the situation that would work for any time, x. Type your equation into Desmos to make a graph that represents her experiment. Take a screenshot that includes both the equation and the graph in Desmos. Paste the screenshot to this page or attach it separately to the assignment submission drop box. Please help!!!!
Answer:
This is an exponential function of the form [tex]y=a(b^x)[/tex]We will use the followingy for the number of bacteria at a given timex for the timea for the starting number of bacteria, which is 700b for the base of the exponentso lets find b, we need the following:r, which will be our rate, which is 4.3% or 0.043, so[tex]b=1+r\\b=1+0.043\\b=1.043[/tex] With this info, let's substitute, and get the equation as the answer: [tex]y=700(1.043^x)[/tex] Put that into desmos, (I attached a screenshot for you)Answer:
This is an exponential function of the form
We will use the following
y for the number of bacteria at a given time
x for the time
a for the starting number of bacteria, which is 700
b for the base of the exponent
so lets find b, we need the following:
r, which will be our rate, which is 4.3% or 0.043, so
With this info, let's substitute, and get the equation as the answer:
Put that into decimals, (I attached a screenshot for you)

Alex says that there is no numbers between 1/3 and 1/4 . Why might he think that and what would you tell him? Is there a number that falls between these?
Answer:
Why might he think that and what would you tell him?
He thought perhaps that numbers were formed by rational numbers of the form [tex]\frac{1}{x}[/tex], where [tex]x\in \mathbb{N}[/tex]. I would tell him that there are rational numbers [tex]\frac{y}{z}[/tex], such that [tex]\frac{1}{x}\le \frac{y}{z} \le \frac{1}{x+1}[/tex], where [tex]x[/tex], [tex]y[/tex], [tex]z \in \mathbb{N}[/tex].
Is there a number that falls between these?
[tex]\frac{7}{24}[/tex] is a rational number between [tex]\frac{1}{3}[/tex] and [tex]\frac{1}{4}[/tex].
Step-by-step explanation:
Why might he think that and what would you tell him?
He thought perhaps that numbers were formed by rational numbers of the form [tex]\frac{1}{x}[/tex], where [tex]x\in \mathbb{N}[/tex]. I would tell him that there are rational numbers [tex]\frac{y}{z}[/tex], such that [tex]\frac{1}{x}\le \frac{y}{z} \le \frac{1}{x+1}[/tex], where [tex]x[/tex], [tex]y[/tex], [tex]z \in \mathbb{N}[/tex].
Is there a number that falls between these?
Indeed, the average number of [tex]\frac{1}{3}[/tex] and [tex]\frac{1}{4}[/tex], for instance. That is:
[tex]\frac{y}{z} = \frac{\frac{1}{3}+\frac{1}{4} }{2}[/tex]
[tex]\frac{y}{z} = \frac{\frac{7}{12} }{2}[/tex]
[tex]\frac{y}{z} = \frac{7}{24}[/tex]
[tex]\frac{7}{24}[/tex] is a rational number between [tex]\frac{1}{3}[/tex] and [tex]\frac{1}{4}[/tex].

If AFGH
AQRS, find the measure of Q.
Answer:
D. 28°
Step-by-step explanation:
Since ∆FGH is congruent to ∆QRS, it follows that:
[tex] m\angle F = m\angle Q [/tex]
Thus:
[tex] 2x + 10 = 3x + 1 [/tex] (Substitution)
Collect like terms
[tex] 2x - 3x = -10 + 1 [/tex]
[tex] -x = -9 [/tex]
Divide both sides by -1
x = 9
[tex] \angle Q = 3x + 1 [/tex]
Plug in the value of x
[tex] \angle Q = 3(9) + 1 [/tex]
[tex] \angle Q = 28 degrees [/tex]

Mrs. Myane had 3/5 kg of sugar. She used 1/4 of it to make fruit pies. How much sugar did she use to make the fruit pies?
Answer:
3/20
Step-by-step explanation:
What if Mrs. Myane used a similar approach to the problem, but used simpler numbers? Consider this:
Mrs. Myane had 8 kg of sugar. She used 1/4 of it to make fruit pies. How much sugar did she use to make the fruit pies?
We can see that all we need to do here is divide by four or multiply 1/4. Using the same technique, we can figure out that (in the original problem) Mrs. Myane can create an expression similar to this:
(3/5)*(1/4)
This expression can work too: (3/5) ÷ 4
Following that, we get (3/20).
Good luck and keep studying! Apologies for the late reply. I hope it still helps!

Sumi rides at a constant speed of 10 ft/s. Write an equation that expresses the distance d that sumi has traveled as a function of the time s in seconds since she started riding her bike
Answer:
d = 10s
Step-by-step explanation:
The formula for calculating the speed of Sumi is expressed as;
Speed = distance/time
Given
Speed = 10ft/s
time = s seconds
Required
Distance travelled as a function of time;
from the formula;
Distance = Speed * time
Distance = 10 * s
d = 10s
Hence the equation that expresses the distance d that sumi has traveled as a function of the time s in seconds since she started riding her bike is;
d = 10s

Step-by-step explanation:
Two angles whose measures have a sum of 90° are called complimentary angles. Let x and y represent the measures of complimentary angles. Use this information and the equation given in the problem to find the measure of each angle. x = 5y
9514 1404 393
Answer:
x = 75°y = 15°Step-by-step explanation:
The correct description of the angles is complementary. "Complimentary" is something else.
x + y = 90 . . . relationship of complementary angles
x = 5y . . . . . given
5y +y = 90 . . . . substitute for x
y = 15 . . . . . divide by 6
x = 75 . . . . . use x=5y
Angle x is 75°; angle y is 15°.
Which graph represents y as a function of x?
The answer is D because the line goes through the x-axis

Answer:
transaction amount for transaction 3 is: -155.15
transaction amount for transaction 4 is: -223.75
Step-by-step explanation:
We need to fill the blanks in the table.
For Transaction 3 and 4 we need to find the transaction amount.
For Transaction 3
The account balance after transaction 2 was 337.50 and account balance after transaction 3 was 182.35.
The transaction amount is: 337.50-182.35 = 155.15
So, transaction amount for transaction 3 is: -155.15
For Transaction 4
The account balance after transaction 3 was 182.35 and account balance after transaction 4 was -41.40
The transaction amount is: -41.40-182.35 = -223.75
So, transaction amount for transaction 4 is: -223.75
