Answer:
Store A
Step-by-step explanation:
Store A
50/100=0.5
0.5×5=2.5
The watch will be 50-2.5=47.5
Store B
60/100=0.6
0.6×20=12
The watch will be 60-12=48
So the watch price in store A is better
Answer:
You should buy from Store A because you're paying $0.50 less than if you were to buy from Store B.
Step-by-step explanation:
First, don't subtract if it's a percentage. You will want to multiply to get the amount you're removing from the original price.
Let's look at Store A. $50 and 5% discount. 50 * 0.05 = 2.5. Remove 2.5 from 50.
50 - 2.5 = 47.5
When you buy from Store A, you will pay $47.5
Let's look at Store B. $60 and 20% discount. 60 * 0.20 = 12. Remove 12 from 60.
60 - 12 = 48
When you buy from Store B, you will pay $48
Ultimately, Store A is the best option because you're paying less.

23) You are late for work. You have two options for getting to work. You may take the bus which takes on average 40 minutes with a standard deviation of 12 minutes. Or you can cycle which takes on average 50 minutes with a standard deviation of 2 minutes. Compare these two distributions.
You leave your house at 8.05 am and are supposed to start work at 9.00 am.
Which option would you choose if you will be fired if you are even a few minutes late?
Answer:
either of them because you wont be late because it only takes 52 minutes for both

Jeff modeled the number of minutes that he read each day during the first week of the summer. The recursive function, f(x), can be used to determine the number of minutes that he had read after a certain number of days, where x represents the number of days. f(1) = 28 f(x) = f(x - 1) + 8 Use the recursive function to find the number of minutes that Jeff read after 3 days of summer.
9514 1404 393
Answer:
44 minutes
Step-by-step explanation:
We are given f(1) = 28.
Using the recursive formula ...
f(2) = f(1) +8 = 28 +8 = 36
f(3) = f(2) +8 = 36 +8 = 44
Jeff read 44 minutes after 3 days of summer.

On a very cold morning, it was -7°F. As the day went on, the temperature rose 3 degrees each hour. Which equation shows the temperature over time?
A.y=-3x-7
B.y=-3x+7
C.y=3x-7
D.y=3x+7
Answer:
The equation shows the temperature over time will be:
[tex]y = 3x - 7[/tex]Hence, option (C) is correct.
Step-by-step explanation:
We know that the slope-intercept form of the line equation is
[tex]y=mx+b[/tex]
where m is the rate of change or slope and b is the y-intercept
Let 'y' be the temperatureLet 'x' be the time in the hour
Given that one very cold morning, it was -7°F.
Thus, the y-intercept = b = -7
Given that as the day went on, the temperature rose 3 degrees each hour.
Thus, the rate of change = slope = m = 3
Thus, substituting m = 3 and b = -7 in the equation
[tex]y = mx+b[/tex]
[tex]y = 3x + (-7)[/tex]
[tex]y = 3x - 7[/tex]
Therefore, the equation shows the temperature over time will be:
[tex]y = 3x - 7[/tex]Hence, option (C) is correct.

4x−2(x−4)=−3+4x+5 please I need help
Answer:
x=3
Step-by-step explanation:
4x−2(x−4)=−3+4x+5
4x+(−2)(x)+(−2)(−4)=−3+4x+5
4x+−2x+8=−3+4x+5
(4x+−2x)+(8)=(4x)+(−3+5)
2x+8=4x+2
2x+8−4x=4x+2−4x
−2x+8=2
−2x+8−8=2−8
−2x=−6
−2x /−2 = −6 /−2

Step-by-step explanation:
to compound 50% solution in which proportion must 95% sol and 30% sol be mixed to make
500 ml
Answer:
4/9
Step-by-step explanation:
Let the amount of 95% sol = a ml and
the amount of 30% sol = b ml.
So, the total amount of the compound=a+b=500 ml
As the compound is 50% solution, so
95% of a + 30% of b= 50% of (a+b)
(95/100)a+(30/100)b=(50/100)(a+b) [from equation (i)]
95a + 30b = 50(a+b)
95(a/b)+30 = 50(a+b)/b [dividing both sides by b]
95(a/b)+30 = 50(a/b+1)
95(a/b)+30 = 50(a/b)+50
95(a/b)-50(a/b)=50-30
45(a/b)=20
a/b=20/45
a/b=4/9
Therefore, a:b=4:9
As a+b= 500 ml, so the amount of 95% sol = [tex]\frac {500}{13}\times 4=\frac{2000}{13}=153.85[/tex] ml
and the amount of 95% sol = [tex]\frac {500}{13}\times 9=\frac{4500}{13}=346.15[/tex] ml
Hence, the proportion of 95% sol and 30% sol to make a compound of 50% sol must be 4/9.

Find the values of a and b so that the linear system has the given solution.
Given Solution: (2, 1)
Equation 1: ax - by'= 4
Equation 2: bx - ay = 10
Answer:
The values are a=6, b=8
Step-by-step explanation:
System of Equations
We are given the system of equations:
ax - by = 4
bx - ay = 10
And it's known the solutions are: x=2, y=1.
Plugging in the solutions:
2a - b = 4 [1]
2b - a = 10 [2]
Now we have to solve the system above. Multiply [1] by 2:
4a - 2b = 8
Now we add with [2]:
3a = 18
a = 18/3 = 6
a = 6
From [2]:
2b - 6 = 10
2b = 16
b = 16/2 = 8
b = 8
The values are a=6, b=8

factor the following
42x+28y
Answer:
To find the GCF, do the prime factorization of both numbers.
42 = 2 x 3 x 7
28 = 2 x 2 x 7
The GCF uses the numbers that appear in BOTH, 2 x 7 = 14 is the GCF of the numbers. There is no variable GCF because there isn't a variable that appears in both.
Taking out the GCF gives you:
14(3x + 2y)
Step-by-step explanation:
Answer:
14(3x + 2y)
Find the GCF.
It is 14.
Use the distributive property.
