HOPE IT HELPED YOUEstimate the percent using decimals.
48% of 400
Step-by-step explanation:
getcalc.com's fraction to decimal calculator to find what's an equivalent decimal for the fractional number 48/400.
50/400 0.125 12.5%
49/400 0.1225 12.25%
48/400 0.12 12%
47/400 0.1175 11.75%
Answer:
fraction to decimal calculator to find what's an equivalent decimal for the fractional number 48/400.
0.12 is a decimal and 12/100 or 12% is the percentage for 48/400.
Step-by-step explanation:
A fraction consists of two numbers and a fraction bar:
48/400
The number above the bar is the numerator: 48
The number below the bar is the denominator: 400
Divide the numerator by the denominator to get fraction's value:
Val = 48 ÷ 400
Introduction. Percent, p%
'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% = p/100 = p ÷ 100.
Calculate fraction's value.
Divide the numerator by the denominator to get fraction's value:
48/400 =
48 ÷ 400 =
0.12
Note:
100/100 = 100 ÷ 100 = 100% = 1
Multiply a number by the fraction 100/100,
... and its value doesn't change.
Calculate the percent value:
0.12 =
0.12 × 100/100 =
(0.12 × 100)/100 =
12/100 =
12%;
Hope it is helpful...A fountain holds 12500 7/8 gallons of water. Joe wants to calculate how many liters that is. Which proportion could he use to solve for the number of liters? (1 gal = 3.79 L)
Answer:
47378.31625 Liters
Step-by-step explanation:
A fountain holds 12500 7/8 gallons of water. Joe wants to calculate how many liters that is. Which proportion could he use to solve for the number of liters? (1 gal = 3.79 L)
From the above question,
1 gallon = 3.79 Liters
12500 7/8 gallons = x Liters
Cross Multiply
x Liters = 12500 7/8 × 3.79 Liters
x = 47378.31625 Liters
Therefore, the number of liters of water in the fountain is 47378.31625 Liters
An electric car can travel at top speed for 107 km on 5 h charging time. If the car died after just traveling 65 km at top speed, how long a charge could it have held?
A.) 4h B.) 2.5h C.) 3h D.) 3.5h
9514 1404 393
Answer:
C.) 3 h
Step-by-step explanation:
If you assume the distance is proportional to the charge time, then ...
x/5 = 65/107
x = 5(65/107) ≈ 3.04
The car may have held about a 3-hour charge.

THANK YOU :D
Answer:
p=$20000
t=?
rateR =15%
d=20000/2=10000
Step-by-step explanation:
we have
d=p(1-r/100)^t
10000=20000(1-15/100)^t
10000/20000=85/100^t
1/2=0.85^t
sorry. i did not get answer after this.

First three terms of a sequence is shown below. Determine if the sequence is geometric. If so, state the common ratio.
30, 10, 103, ...
a.The sequence is geometric, and the common ratio is 13.
b.The sequence is geometric, and the common ratio is 3.
c.The sequence is geometric, and the common ratio is -20.
d.The sequence is not geometric.
Answer:
Step-by-step explanation:
The common ratio is a constant found by dividing any term by the previous term.
10/30=1/3
103/10=10.3
Since those fractions are not equal this is NOT a geometric sequence.

What is the area of this compound shape?
Answer:
139.36
Step-by-step explanation:
first you do 8*8 because that would be the area of the square part
8*8=64
then find the area of the semicircle
first the Radis of it is 4 because 8/2=4
A=3.14R^2/2
3.14*4^2/2
3.14*16/2
50.24/2
25.12
now because there are 3 of the semicircles you do
25.12*3
75.36
then you add the 64 from the square to get your answer
75.36+64
139.36

A container contains 3 yellow, 2 orange, and 4 pink roses. Without looking, if James chooses a rose from the container, what is the probability that James will select an orange rose?
Answer:
Orange rose = 2/9
Step-by-step explanation:
In order to find probability of picking one item, you add all the possible things you could choose. So, 3+2+4 equals a total of 9 outcomes, and that would be your denominator for your fraction of probability. From there it's really easy. Just put the amount of things your trying to find the probability for in the numerator spot.
Ex.
There are 9 total roses so that would be the denominator (?/9)
To find out the probability for picking an orange rose, you'd put the 2 in as the numerator because that is the total number of orange roses you have (2/?)
Then just put the two together (2/9).
How many times smaller is 2 × 10 to the negative 8th power than 4 × 10 to the negative 7 power?
A. 20
B. 200
C. 0.2
D. 2,000
Answer:
A. 20Step-by-step explanation:
How many times smaller is 2 × 10⁻⁸ than 4 × 10⁻⁷ ?
Rewrite the numbers with the same power of 10:
2 × 10⁻⁸ and 40 × 10⁻⁸Divide the second number by the first, cancel the powers as they are same:
40/2 = 20Correct option is A
The values are
2×10-⁸ and 4×01^{-7}Divide to find how many times smaller
4/2×10^{-7+8}2(10)20timesPlease answer and thank you

Suppose that baby grand piano cost $8000 and looses 15%
in value each year. What would be the value of the piano in
12 years? Round your answer to the nearest hundred.
A.) $1137.93
B.) $1274.88
C.) $1078.44
D.) $5780.00
Answer:
A
Step-by-step explanation:
If it loses 15% of its value every year, then each subsequent year will be worth 85% of the previous year. If we think of this as a geometric series, then the worth would be 8000(.85^t) where t is years after the first year. If you plug in 12, then it's 1137.93.
Answer:
1137.93 is the answer
