Answer: Number of small boxes = 7, Number of large boxes =3
Step-by-step explanation:
Let x= Number of small boxes , y = Number of large boxes.
As per given , 30x+55y=375 (i)
x+y=10 (ii)
Multiply (ii) by 30, we get
30x+30y=300 (iii)
Eliminate (iii) from (i), we get
25y=75
⇒ y= 3 [Divide both sides by 25]
Put y=3 in (ii), we get
x+3=10 ⇒ x=7
Hence, Number of small boxes = 7, Number of large boxes =3

Jocelyn is going to invest in an account paying an interest rate of 2.3% compounded
continuously. How much would Jocelyn need to invest, to the nearest hundred
dollars, for the value of the account to reach $550 in 15 years?
9514 1404 393
Answer:
$400
Step-by-step explanation:
The formula for the value of an account with interest rate r compounded continuously for t years is ...
A = Pe^(rt)
We want to find P when A = 550, r = .023, and t = 15.
550 = Pe^(0.023·15) ≈ 1.41199P
P = 550/1.41199 = 389.52 ≈ 400
Jocelyn would need to invest about $400 to reach $550 in 15 years.
I need an answer! Madison Middle School sells rolls of wrapping paper to raise money for student activities. The school gets half of all sales, minus $300 for prizes to top sellers. What is the total sales if the school earns $5000?
Answer:
$10,600 worth of wrapping paper
Step-by-step explanation:
Let the total sales for wrapping paper be represented by variable x
Amount the school keeps is half of total sales x, minus $300. Written as an equation, that would be ; 0.5x - 300
If the schools wants to earn $5000, this amount would be equal to the above equation of what it keeps;
0.5x - 300 = 5000
add 300 to both sides;
0.5x = 5000+300
0.5x = 5300
divide both sides by 0.5 and solve for x;
x=5300 / 0.5
x= 10,600
Therefore, they need to sell $10,600 worth of wrapping paper.
hope dat good?
When Marcus weighs himself at home, he weighs 179 lbs. When he weighs himself on a metric scale, he weighs 81.4 kg. Assuming that each scale is accurate, 1 kg = ______ lbs ?
Answer:
2.199 lbs
Step-by-step explanation:
We can divide 179 by 81.4 to get how many pounds there are per kilogram. When we do this, we get 2.19 pounds per kilogram. We know this because we divided both sides by 81.4 as shown here:
81.4kg = 179lbs
/ /
81.4 81.4
1kg = 2.199 lbs

Step-by-step explanation:
The volume V of an ideal gas varies directly with the temperature T and inversely with the pressure P. cylinder 50 liters contains oxygen at a temperature of 200 K and a pressure of 6 atmospheres , what would the gas pressure be if the volume was changed to 25 liters and the temperature raised to 250 K?
Answer:
15 atm
Step-by-step explanation:
V varies directly with T and inversely with P.
V = kT/P
When T = 200 and P = 6, V = 50.
50 = k (200) / (6)
k = 1.5
When V = 25 and T = 250:
25 = 1.5 (250) / P
P = 15
Given that we know the relation between volume, pressure and temperature (given for the ideal gas), we want to find the change in pressure associated to the given change in volume and temperature.
We will see that the pressure after the change is 15 atm.
Let's see how to solve this problem:
So we start by knowing that the volume depends directly on the temperature and inversely on the pressure, then the relation is something like:
V = k*(T/P)
Where k is a constant.
We know that a cylinder of 50lt is at a temperature of 200K and with a pressure of 6 atm, replacing that in the above equation we get:
50lt = k*(200K/6atm)
With this we can find the value of k:
50lt*(6atm/200K) = k = 1.5 lt*atm/K
Then the equation is just:
V = (1.5 lt*atm/K)*(T/P)
Now the problem says that the volume is 25lt and the temperature is 250K, replacing that in the equation we get:
25lt = (1.5 lt*atm/K)*(250K/P)
Solving for P we have:
P = (1.5 lt*atm/K)*(250K/25lt) = 15atm
Concluding, the pressure is after the change is 15 atm

if JK+LM=NP+LM then JK=NP what property is this
Answer:
Subtraction propertyStep-by-step explanation:
Given JK+LM=NP+LM
To show that JK = NP, we will subtract LM from both sides
JK+LM-LM=NP+LM -LM
JK = NP
Since we subtracted LM from both sides without affecting the nature of the equality sign, then the property used is the subtraction property

15. Jorge is getting a loan from the bank for a new car. The loan amount is $25,000. The bank will compound the interest annually for 6 years at 4%. What will be the total amount of the loan at the end of the 4 years?
Answer:
$120000Step-by-step explanation:
"15. Jorge is getting a loan from the bank for a new car. The loan amount is $25,000. The bank will compound the interest annually for 6 years at 4%. What will be the total amount of the loan at the end of the 4 years?"
the expression for compound interest is given as
A=P(1+r)^t
given data
Principal P=$25000
rate r=4%= 0.04
time t= 4years
Substituting into the expression we have
A=P(1+r)^t
A=25000(1+0.04)^4
A=25000(1.04)^4
A=25000x4.80
A=$120000
The total amount of loan after 4 years is $120000

The length of a garden is 10 feet longer than three times the width. The perimeter of the garden is 240 feet. Find the length and the width of the garden.
Answer: width = 27.5 feet and length = 92.5 feet
Step-by-step explanation:
Let width = x, then length = 3x+10
Perimeter of rectangle = 2 (length +width)
Given: Perimeter of the garden = 240 feet.
Then, [tex]2 (x+3x+10)=240[/tex]
[tex]\Rightarrow\ 2 (x+3x+10)=240\\\\\Rightarrow\ (4x+10)=120\\\\\Rightarrow\ 4x=110\\\\\Rightarrow\ x=\dfrac{110}{4}=27.5[/tex]
i.e. width = 27.5 feet
Then, length = 3(27.5)+10= 82.5+10=92.5 feet
Hence, width = 27.5 feet and length = 92.5 feet
