Samir had 30 dollars to spend on 3 gifts. He spent 9
9
10
dollars on gift A and 5
3
5
dollars on gift B. How much money did he have left for gift C?
Answer:
Gift 1 ($9) Gift 2 ($10)
Step-by-step explanation:
First we know that Samir had 30 dollars to spend on 3 gifts. If he bought gift 1 for $9, and gift 2 for $10. Then Samir should have $11 for gift 3 that he can spend.
9+10=$19, $30-19=$11 Hope This helps! Mark Brainllest if it is correct!
Hence, the money did he have left for gift C is [tex]15.5[/tex].
What is the simplification?
Simplification is the process of replacing a mathematical expression by an equivalent one, that is simpler (usually shorter), for example Simplification of a fraction to an irreducible fraction.
Here given that,
Samir had [tex]30[/tex] dollars to spend on [tex]3[/tex] gifts. He spent [tex]9.\frac{9}{10}[/tex] dollars on gift A and [tex]4.\frac{3}{5}[/tex] dollars on gift B.
So,
[tex]A=9.\frac{9}{10}\\\\A=\frac{90+9}{10}\\\\A=\frac{99}{10}\\\\A=9.9[/tex]
[tex]B=4.\frac{3}{5}\\\\B=\frac{20+3}{5}\\\\B=\frac{23}{5}\\\\B=4.6[/tex]
To find out the money did he have left for gift C is
[tex]A+B+C=G[/tex]
Here,
[tex]A=9.9\\B=4.6\\G=30[/tex]
Then,
[tex]9.9+4.6+C=30\\\\C=30-9.9-4.6\\\\C=30-14.5\\\\C=15.5[/tex]
Hence, the money did he have left for gift C is [tex]15.5[/tex].

How many liters of water are in a tank with a volume of 4,500 cm3
1 L = 1,000 cm
04.0L
0 4.5 L

Another statement is, "Volume is directly proportional to the number of moles."
The volume increases as the number of moles increases. It does not depend on the sizes or the masses of the molecules.

Equal volumes of hydrogen, oxygen, or carbon dioxide contain the same number of molecules.

Naomi and Hudson work at a dry cleaners ironing shirts. Naomi can iron 35 shirts per hour, and Hudson can iron 20 shirts per hour. Naomi and Hudson worked a combined 13 hours and ironed 395 shirts. Write a system of equations that could be used to determine the number of hours Naomi worked and the number of hours Hudson worked. Define the variables that you use to write the system.
Answer:
Given that Naomi and Hudson work at a dry cleaners ironing shirts, and Naomi can iron 35 shirts per hour, while Hudson can iron 20 shirts per hour, knowing that Naomi and Hudson worked a combined 13 hours and ironed 395 shirts, to write a system of equations that could be used to determine the number of hours Naomi worked and the number of hours Hudson worked, the following logical reasoning should be performed:
Naomi, working 13 hours, can iron up to 455 shirts (13 x 35), with which, every hour that Hudson has worked and she does not imply a decrease of 15 ironed shirts. Since 455 - 395 equals 60, and 60/20 equals 3, it is determined that Hudson worked 3 hours, while Naomi worked 10 hours.
Thus, the proposed inequality would be the following:
35Y + 20X = 395

Rita is designing a building shaped like a pyramid that's cut off in a plane parallel to its base (this is called a truncated pyramid). The building has a 64×64 m end text square base and is 36 m tall. The cut off section has a16×16m square base and is 12 m tall. What is the volume of the building? Round to the nearest cubic meter.
Area of full pyramid: = 1/3 x area of base x height
Area = 1/3 x 64^2 x 36 = 49,152 cubic meters
Area of top section: 1/3 x 16^2 x 12 = 1,024 cubic meters
Total volume of truncated pyramid = 49,152 - 1,024 = 48,128 cubic meters
Nimer was driving to a hotel. He looked at his sat nav at 13:30 and saw the following distance to destination = 65miles nimer arrived at the hotel at 14:48 work out the average speed of the car in mph, from 13:30 to 14:48
Answer:Average speed =50 miles per hour or 50mph
Step-by-step explanation:
We know that Speed is given as= Distance/ Time
Nimer's distance to his destination = 65 miles
Time taken to his destination = 13:30 to 14:48
which is = 14:48--13:30 = 1:18 mins
Converting 1hr 18mins to hours = 1 hour + 18/ 60 = 1 + 0.3 = 1.3 hours
Average speed =Distance/ Time
Average speed = 65miles/ 1.3hr = 50 miles per hour
