1/9 of the shirts sold at Peter’s shop are striped. 5/8 of the remainder are printed. The rest of the shirt are plain colored shirts. If Peter’s shop has 81 plain colored shirts, how many more printed shirts than plain colored shirts does the shop have?\
Thanks
Spectrier
Answers
Answer:
54 more printed than plain shirts.
Step-by-step explanation:
Alright, so... if 1/9 of the shirts are striped and 5/8 of the remaining shirts are printed then 3/8 of the remaining shirts are plain. if 81=3/8 of the remaining shirts then 1/8 of the remaining shirts is 27 shirts. 27x5=135 meaning 135 of the remaning shirts are printed. If 1/8 of the remaining shirts is 27, there are 216 total remaining shirts. This also means that 216 is 8/9 of all of the shirts. Since 27 is 1/8 of the remaining shirts, 216+27=the total amount of shirts. 216+27=243. 243/9=27 meaning that 1/9 of the shirts is 27 (which also means I did that math for no reason, it's 2:00 am, my brain can't funtion rn XD). 135 printed shirts-81 plain shirts=54. There are 54 more printed shirts than plain shirts. Sorry if I am wrong, hope it helps. Have a wonderful day!

A sign says that the price on all music equipment is 30% off the original price. you buy an electric guitar for the sale price of $315.
A-what is the original price?
B-How much money did you save off of the original price?
C-What percent of the original price is the sale price?
Answers
Answer:
a. So the electric guitar is sold for a sale price of $315 after the discount. The discount was 30%. Even though we get that amount off, we still pay 70% of the original price, because 100% (original price) - 30% is 70%.
b. An equation that can help us find the regular price of the item is through writing and solving a proportion. Set it up like this:
315/x = 70/100
This is because 315 is part of the whole and is 70% of the value of x.
Step-by-step explanation:
Okay. Let's solve this by cross multiplying the values. 315 * 100 is 31,500. 70 * x is 70x. That simplifies to 31,500 = 70x. Didivde each side by 70 to isolate the x. 70x/70 cancels out. 31,500/70 is 450. Let's check this by multiply the number by 70% and see what happens. 450 * 70% (0.7) is 315. There. x = 450. The regular price was $450.
Answer:
a. $450
b. $135
c. 70%
Step-by-step:
[tex]\frac{70}{100} = \frac{315}{450}[/tex] since these two fractions are equal to each other that means the orginal price is $450.
(sale price/original price)x100= % of original price
(315/450)x100=0.7=70%

Step-by-step explanation:
Answer:
c)
Step-by-step explanation:
so we know that the total amount of students in said school is 180, which means that the total amount of girls in this school cannot be greater than 180
with that, let us get to solving these equations to see which one is less than 180-
a) 85/10*180=1530>180
b) 850/100*180=1530>180
c)0.85*180=153
'c' is the only answer choice less than 180>153
another way to solve this would be to focus solely
on answer choice 'c'-
so 85% of the school is female and 85% as a fraction is 0.85, and we need to find the total amount of girls that attend said school and the only way to do that is to multiply-
0.85*180=153>180
good luck :)

At his favorite restaurant, Dylan orders a soda with his dinner. The ice in his drink has a mass of 6 g and a volume of 20 cm3. What is the density of the ice? Explain the steps you took to solve this problem.
Answers
Answer:
0.3
Step-by-step explanation
The formula to find density is m/v=p
m=mass
v=volume
p=density
---------------------------All we have to do is plug in 6g and 20cm^3
This will give us 6/20 which simplifies to 3/10
With this you can easily figure out that the decimal for 3/10 is 0.3
So the density of the ice is 0.3
