At a cafeteria, Mary orders two pieces of toast and a bagel, which comes out to $\$3.15$. Mary orders a bagel and a muffin, which comes out to $\$3.30$. Mary orders a piece of toast, two bagels, and three muffins, which comes out to $\$9.15$. How many cents does one bagel cost
On solving the question, by linear equation One bagel is 100*1.55 = 155 cents in dollars.
What is a linear equation?A linear equation is one that has the form y=mx+b in algebra. B is the slope, and m is the y-intercept.
A toast costs = x dollars.
A bagel costs = y dollars.
A muffin costs = z dollars.
It costs $3.15 for two pieces of toast and a bagel.
As a result, 2x + y = 3.15. To get the price of a bagel, we express x as a function of y,
2x = 3.15 —Y
x = -o.5y+ 1.575
It costs $3.30 for a bagel and a muffin.
Since x and z are functions of y,
—0.5y + 1.575 + + 3(3.3 — y) 9.15
—0.5y + 1.575 +2y + 9.9—3y = 9.15
—1.5y + 11.475 = 9.15
1.5y = 2.325
2.325
Y = 1.55
One bagel is 100*1.55 = 155 cents in dollars.

I'm bad at math so uh yeahhh
Answer and Step-by-step explanation:
Since we know that lines l and m are parallel (we are just proving that they are parallel), we can see that the two angles given are corresponding angles, so they are congruent to each other.
123 = 2x + 7
Subtract 7 from both sides.
116 = 2x
Now, divide both sides by 2.
58 = x
So, the value of x is 58.

Using a table of values, what is the approximate positive solution to the equation to the nearest quarter of a unit? f(x)=log(x+2) g(x)=4^x-1
Answer:
The answer is 0.25 for plato/edmentum users
Step-by-step explanation:
The x-intercept/zero for function f is x= -1 and the x-intercept/zero for function g is x= 0, therefore, the closest positive value out of the options is 0.25 sense the problem wants the functions to equal around the same value. Tbh I suck at math and idek if my explanation is right I really just guessed on the problem. Here's a ss for proof that my answer's right tho lol p.s. if ur 15-19 amos: kenz8124 Have a great day :)
The positive solution to the equation is 0.21
The functions are given as:
[tex]f(x) = \log(x + 2)[/tex].[tex]g(x) = 4^x - 1[/tex].The tables are not given. So, we make use of graphs
Graphs of f(x) and g(x)See attachment for the graph that represents functions f(x) and g(x).
From the attached graph, we can see that the curves of both functions intersect at x = 0.214.
Approximate the above value of x
[tex]x =0.21[/tex]
Hence, the positive solution to the equation is 0.21

A picosecond in one trillionth of a second. How many picoseconds are there in 12 minutes?
Answer:
720,000,000,000,000 or 720 trillion picoseconds.
Step-by-step explanation:
1 picosecond = 1 trillionth of a second. Therefore 1 second has 1 trillion picoseconds:
0.000 000 000 001 seconds = 1 picosecond
0.000 000 000 001 * 1,000,000,000,000 seconds = 1 * 1,000,000,000,000 picosecond
1 second = 1,000,000,000,000 picoseconds
Now, one minute is the same as 60 seconds so we multiply the equation by 60:
1 minute = 60 seconds = 60,000,000,000,000 picoseconds
Finally, we need 12 minutes to be converted to picoseconds.
12 minutes = 720 seconds = 720,000,000,000,000 picoseconds.
So therefore, 12 minutes is equal to 720,000,000,000,000 picoseconds or 720 trillion picoseconds.

the diameter of a circle is 9 in . find its area to the nearest tenth.
Answer:
63.6
Step-by-step explanation:
diameter = 9
radius = 9/2= 4.5
Area of circle = 22/7 × radius²
so,
22/7×4.5×4.5 = 63.6428571
if we round off it to nearest tenth it will be = 63.6
Each square inch of your body has about 6. 5 × 10^2 pores. Suppose the top of your foot has an area of about 2. 0 × 10^1 in. ^2. About how many pores are on the top of your foot?
The number of pores that are on the top of your foot is approximately 13,000 pores on the top of your foot.
To find the number of pores on the top of your foot, we can multiply the area of the top of your foot in square inches by the number of pores per square inch.
The area of the top of your foot is 2.0 x 10^1 in^2 and each square inch of your body has about 6.5 x 10^2 pores. So, the number of pores on the top of your foot can be calculated as:
2.0 x 10^1 in^2 * 6.5 x 10^2 pores/in^2 = 130 x 10^2 pores = 13000 pores
So, there are approximately 13,000 pores on the top of your foot.

Here, 1/3 is halfway between 0 and 1. The exponential function supplied has a decay factor of 1/3 as a result.
How do you find the decay factor of an exponential function?An exponential function's basic form is:
[tex]$$y=a b^x$$[/tex]
Where an is the starting value, b>1 is the growth factor, and 0b1 is the decay factor.
the point through which the exponential function passes (0,6). In I if x=0 and y=6, we obtain
[tex]$$\begin{aligned}& 6=a b^0 \\& 6=a(1) \\& 6=a\end{aligned}$$[/tex]
the point through which the exponential function passes (1,2). Substituting [tex]$x=1, y=2, a=6$[/tex] in (i), we get
[tex]$$\begin{aligned}2 & =6(b)^1 \\2 & =6 b \\\frac{2}{6} & =b \\\frac{1}{3} & =b\end{aligned}$$[/tex]
Here, [tex]$^{b=\frac{1}{3}}$[/tex] between 0 and 1 is located. The provided exponential function's decay factor is thus [tex]$\frac{1}{3}$[/tex].

Answer:
Although i am not sure, I believe the answer is 56.
Step-by-step explanation:
A right angle is 90 degrees.
90 - 28 = 62
by the looks of it, the angle on to of the place of the 62 looks identical, so i will assume it is also 62 degrees.
62 + 62 = 124
180 - 124 = 56
So that is why I believe it is 56.

Mike is a sales person in a retail carpet store he paid 500 base salary per month plus 5% commission on sales over 10,000. His sales this month were 23,750 his total deductions were 152.75 What is the total amount on which mike could earn commission? What was the total amount of mikes commission? What was mikes base salary plus commission? What's mike net pay?
Answer:
Total amount on which Mike could earn commission:
Mike can earn amounts on sales over $10,000 so the commission amount is:
= 23,750 - 10,000
= $13,750
Total amount of Mike's compensation:
= 5% * 13,750
= $687.50
Mikes base salary plus commission:
= 500 + 687.50
= $1,187.50
Mike's net pay:
= Gross pay - deductions
= 1,187.50 - 152.75
= $1,034.75

Salesman A works strictly on commission. He earns $65 per sale, with a maximum weekly commission of $1,300.
PLS HELP ME IM ABT TO CRY!!!! 100 PTS
Salesman B earns a weekly base salary of $300, plus a commission of $40 per sale. There are no limits on the amount of commission he can earn.
Salesman C does not earn any commission. His weekly salary is $900.
If Salesman A has exactly ____ sales, he will reach his maximum weekly commission.
Answer:
Sales = 20
Step-by-step explanation:
Simply make the equation "1300 = 65s" to solve the problem
1300 = 65s
Divide both sides by 65.
1300/65 = 65s/65
Divide 1300 by 65 to get 20.
20=s
Swap sides so that all variable terms are on the left-hand side.
