simplify this Problem 1.5 x 1.5
Answer:
2.25
Step-by-step explanation:
1.5 times 1.5 is 2.25
"simplify" just means to solve in ur case..
Hope this helps!!
1.5 multiplied by 1.5 equals 2.25.
To simplify the problem 1.5 x 1.5, you can multiply the two numbers together.
To calculate this, you can follow these steps:
Multiply the first digit of the first number (1) by the first digit of the second number (also 1): 1 x 1 = 1.
Multiply the decimal parts of both numbers: 0.5 x 0.5 = 0.25.
Add the results from step 1 and step 2 together: 1 + 0.25 = 1.25.
The final answer is 1.25, but we need to consider the decimal places. Since both numbers have one decimal place, the final answer will have two decimal places: 2.25.
Therefore, 1.5 x 1.5 simplifies to 2.25.

Rodger put $1,000 in a bank account that pays 5% annual simple interest. At the end of four years, how much interest has he earned and what is the balance of his account
Answer: He has earned $200 interest and the balance of his account is $1,200.
Step-by-step explanation:
Given: Principal : P = $1,000
Simple interest rate : r = 5% = 0.05
Time: t = 4 years
Simple interest = [tex]Prt[/tex]
[tex]=1000\times0.05\times4=200[/tex]
i.e. Simple interest = $200
Balance of account = Principal + Simple interest
= $1,000 + $200
= $1,200
Hence, he has earned $200 interest and the balance of his account is $1,200.
Express 25 as power with base 5
Answer: express a number in base 5 notation you need to write it in powers of 5. ... 52 = 25 53 = 125 54 = 625. 625 is larger than 613 so I only need a 53 digit, a 52

A TV salesman will make 18% commission on the profit of every TV he sells. If the electronics store buys a TV for $600 and the salesman sells the TV for $899, how much is his commission?
Answer:
Commission= $53.82
Step-by-step explanation:
First, we need to calculate the gross profit of the sale:
Gross profit= sale price - total cost
Gross profit= 899 - 600
Gross profit= $299
Now, the commission made by the seller:
Commission= gross profit*commission rate
Commission= 299*0.28
Commission= $53.82

parking lot 4 had the greatest percentage of blue cars
Step-by-step explanation:
Answer:
Lot 4 had the greatest percentage of blue cars.
Step-by-step explanation:
15 of the 36 cars in lot 1 were blue = 41.66 %
43 of the 92 cars in lot 2 were blue = 46.73 %
12 of the 30 cars in lot 3 were blue = 40%
32 of the 52 cars in lot 4 were blue = 61.53 %
A theater, the admission price for children is $4 and the admission price for adults is $8. The total amount the theater collects in admissions for the day is $1848. The total number of visitors is 283. Let be the number of children and let y be the number of adults. Which system represents the situation?
Answer:
[tex]4x+8y= 1848\\\\x+y= 283[/tex]
Step-by-step explanation:
Step one:
The admission price for children is $4
The admission price for adults is $8
Let be the number of children and
let y be the number of adults.
The total amount the theater collects in admissions for the day is $1848.
4x+8y= 1848-----------1
The total number of visitors is 283.
x+y= 283----------------2
Step two:
the system of equation for the situation is
4x+8y= 1848
x+y= 283
a conical tank with vertex down is 10 feet across the top and 12 feet deep. If water is flowing out of the tank at a rate of 12 cubic feet per minute, find the rate at which the water level is dropping when radius of water level is 4ft.
Answer:
The water level is dropping at a rate of 0.24 ft/s
Step-by-step explanation:
Here, we simply want to calculate the change in depth (height of the cone) , given the volume change
Mathematically, we have the volume of a cone as;
V = 1/3 * π * r^2 * h
we are given dv/dt as 12 ft^3/m
dv/dh = 1/3 * π * r^2
Substituting the value for the radius, we have
dv/dh = 1/3 * 22/7 * 4^2 = 50.29
dh/dt = dh/dv * dv/dt
dh/dv = 1/(dv/dh) = 1/50.29
Thus,
dh/dt = 1/50.29 * 12
dh/dt = 0.24 ft/s

A sum of money invested at the compound interest payable yearly has interest in
2 years and 4 years are Rs. 4,200 and Rs. 9282 respectively. Find the rate of
interest
Answer:
49% and 30% respectively
Step-by-step explanation:
Step one:
Given data
Principal = Rs. 4,200
Final Amount= Rs. 9282 respectively
time = 2 years and
time = 4 years
Required
The rate of interest for 2 and 4 years
Step two:
the compound interest formula is
A= P(1+r)^t
for 2 years
Substitute
[tex]9282= 4200(1+r)^2\\\\9282/4200= (1+r)^2[/tex]
[tex]1+r= \sqrt{\frac{9282}{ 4200} }\\\\1+r= \sqrt{2.21} \\\\1+r= 1.49\\\\r=1.49-1\\\\r= 0.49\\\\[/tex]
the rate is 49%
For 4 years we have
[tex]9282= 4200(1+r)^4\\\\9282/4200= (1+r)^4[/tex]
[tex]1+r= \sqrt[4]{\frac{9282}{4500} } \\\\1+r=\sqrt[4]{2.21} \\\\1+r= 1.30\\\\r=1.30-1\\\\r= 0.30\\\\[/tex]
the rate is 30%
Parker signed up for a streaming music service that costs $6 per month. The service allows Parker to listen to unlimited music, but if he wants to download songs for offline listening, the service charges $0.50 per song. How much total money would Parker have to pay in a month in which he downloaded 50 songs? How much would he have to pay if he downloaded ss songs?
Answer:
Parker will have to pay $31 in a month in which he downloaded 50 songs.
Total amount Parker will pay for s songs = 6 + 0.50s
Step-by-step explanation:
Cost per month = $6
Cost of Offline download = $0.50 per song
A. How much total money would
Parker have to pay in a month in which he downloaded 50 songs?
Total amount Parker will pay = $6 + $0.50(50)
= 6 + 25
= $31
Parker will have to pay $31 in a month in which he downloaded 50 songs.
B. How much would
he have to pay if he downloaded s songs?
Total amount Parker will pay for s songs = $6 + $0.50 * s
= $6 + $0.50s
Total amount Parker will pay for s songs = 6 + 0.50s
