The estimated total cost, y, of a child's toy is partially based on the number of batteries used, x. The cost per battery is $0.50. They toy itself costs $15. Which equation represent the situation?
a
y = 0.50x - 15
b
y = 15x - 0.50
c
y = 15x + 0.50
d
y = 0.50x + 15
Answers
Answer:
D: 0.50x+15
Step-by-step explanation:
batteries used(each)- x, so you add the x in front of 0.50 representing multiplication between the #
you are doing total cost so you are doing addition (obvously) then its a plain $15 for the toy itself therefore,
y=0.50x+15 (hope this made sense)

Answers
Answer: 2/3
Step-by-step explanation:
Books per month is books divided by months
she read 2 books in 3 months, so divide 2/3
2/3 is your answer
Fraction in simplest form is [tex]\frac{2}{3}[/tex] .
Given Lillian read 2 books in 3 months.
So, He read books in one month is [tex]\frac{2}{3}[/tex].

Step-by-step explanation:
H0: u = 150
H1: u ≠ 150
Total sum = 15933.24
N = 100
Mean = 15933.24/100
= 159.3324
σ² = 25954.03 - (159.3324)²/100
σ² = 556.213
σ = √556.213
σ = 23.8162
Testing hypothesis
t = (bar x - u)/ σ/√n
= 159.3324-150/23.8162/√100
= 3.91
We will have a p value of 0.02
0.0002 < 0.01
We reject null hypothesis at 1% level of significance
C. Mean = 159.3324
Se= 2.3936
Df = 100-1 = 99
Critical value at 0.01 = +-2.626
T = x-u/s.e
= -2.626 =( x -150)/2.3936
When we cross multiply and solve this
X = 143.714 for the lower tail
2.626 = (x-159)/2.3936
= 156.286 for upper tail.
We therefore reject H0 at
Bar X <= 143.71
Bar X >= 156.286
At 10%
Critical t = 1.660
-1.660 = (x - 150)/2.3936
Solving this ,
X =146.02 at the lower tail
1.660 = (x-150)/2.3936
X = 153.97
We reject H0 at
X<= 146.03
X>=153.97

The recommended storage temperature for a certain type of squash is 10°C to 13°C. Which inequality
represents the possible storage temperatures F (in degrees Fahrenheit) of the squash.
Answers
Answer:
The simultaneous inequation representing the recomended storage temperature is:
[tex]50\,^{\circ}F \leq T \leq 55.4\,^{\circ}F[/tex]
Step-by-step explanation:
In this case, the statement must be represented mathematically by a simultaneous inequation, in which temperature must be equal to or greater than 10 ºC, expressed in Fahreheit degrees, and equal or less than 13 ºC, expressed in Fahrenheit degrees.
Bounds can be converted into Fahrenheit degrees from Celsius degrees:
[tex]T_{F} = \frac{9}{5} \cdot T_{C}+32\,^{\circ}F[/tex] (Eq. 1)
Where:
[tex]T_{C}[/tex] - Temperature, measured in Celsius degrees.
[tex]T_{F}[/tex] - Temperature, measured in Fahrenheit degrees.
Lower bound ([tex]T_{C} = 10\,^{\circ}C[/tex])
[tex]T_{F} = \frac{9}{5}\cdot (10\,^{\circ}C) + 32\,^{\circ}F[/tex]
[tex]T_{F} = 50\,^{\circ}F[/tex]
Upper bound ([tex]T_{C} = 13\,^{\circ}C[/tex])
[tex]T_{F} = \frac{9}{5}\cdot (13\,^{\circ}C) + 32\,^{\circ}F[/tex]
[tex]T_{F} = 55.4\,^{\circ}F[/tex]
The simultaneous inequation representing the recomended storage temperature is:
[tex]50\,^{\circ}F \leq T \leq 55.4\,^{\circ}F[/tex]

The value of 8 in 8596 is blank the value of 8 in 985
Answers
To do this type of problem we can really sound them out. What I mean by that is say where the 8 is in particular.
When you look at 8596 you say eight THOUSAND. Therefore it is in the thousand spot. Now look at 985 you say nine hundred and EIGHTY five. Because we know that it isn’t in the hundreds spot because 9 is in it then we go to the next value which is the 10’s spot.
Now we want to look at the difference between the 1000 and 10 spot. How do you get 10 to 1000? Multiply by 100 and add two zeros to therefore get 1000. This would mean that the value of 8 in 8596 is 100 times the value of 8 in 985.

A company earns $150 a week for 9 weeks. It then has a loss of 565 a week for 25 weeks. At the end of the 34 weeks what is the company's
balance?
Answers
Answer:
54
Step-by-step explanation:
multiply 9 and 7 which is 63. then multiply 63 by 150 which is 9,450. then multiply 25 and 7 which is 175. then divide 175 and 9,450. and the answer is 54. Yw!!
We need to write and solve an algebraic equation to find the final company's balance.
The answer is: The final balance is -$275.
Let's see how to get that.
First, we know that the company earns $150 per week for 9 weeks, then the total amount of money that the company earns in these 9 weeks is:
$150*9 = $1,350
Then the company losses $65 per week for 25 weeks, then the amount that the company losses is:
$65*25 = $1,625
The final balance will be the difference between what the company earned and what the company lost, then the final balance is:
balance = $1,350 - $1,625 = -$275
This means that the company's final balance is -$275.
