Answer:
mass of empty basket: 1.21 kg
Explanation:
the mass of basket is constant. Let the mass of basket be "b" and mass of each balls be "m"
Make equations:
b + 3(m) = 3.64 ___ equation 1b + 5(m) = 5.26 ___ equation 2solve them simultaneously,
3.64 - 3(m) = 5.26 - 5(m)-3(m) + 5(m) = 5.26 - 3.642(m) = 1.62m = 0.81 kgmass of basket,
b = 3.64 - 3(m)3.64 - 3(0.81 )1.21 kgNow
x+3y=3.64=>x=3.64-3y--(1)x+5y=5.26=>x=5.26-5ySo
3.64-3y=5.26-5y-3y+5y=5.26-3.642y=1.62y=0.81kgSo
x=3.64-3(0.81)=3.64-2.43=1.21kgthat cost $5.20/lb with walnuts

A flowerpot has a circular base with a diameter of 23 centimeters. Find the circumference of the base of the flowerpot. Round to the nearest tenth.
72.2 cm
144.4 cm
1661.1 cm
529 cm
Answer:
A
Step-by-step explanation:
The flowerpot has a diameter of 23 centimeters.
We have to find the circumference of the pot.
The formula for circumference is:
C = [tex]\pi[/tex]d
C = (3.14)(23)
C = 72.22
The problem says to round to the nearest tenth.
72.22 ≈ 72.2

Answer:
I think the difference in distance is 4000 meters / 10 laps.
Step-by-step explanation:
you multiply the number of laps that they ran and then subtract the products with each other and get the meter answer
or you could just subtract the laps and get your lap answer and then multiply that by 400 to also get the same meter answer

These are the current coordinates of the market:-
[tex]\sf{(3,8)}[/tex]
Move it 2 units to the left:-
[tex]\sf{(1,8)}[/tex]
Move it 3 units down:-
[tex]\sf{(1,5)}\longleftarrow\sf{new~coordinates~of~the~market}[/tex]
What was Paul's mistake?
Paul's mistake was:-
He moved the market 3 units to the left and 2 units down, when he should have moved it 2 units to the left and 3 units down.======================================================
note:-Hope everything is clear; if you need any clarification/explanation, kindly let me know, and I will comment and/or edit my answer :)
Answer:
New location: (1, 5)
Paul's mistake: His mistake was that he switched moving 2 units left and 3 units down with 3 units left and 2 units down.
Step-by-step explanation:
The market was previously at (3, 8).
3 – 2 = 1 (subtract the previous market location with what he's moving with: which is 2)
8 – 3 = 5 (subtract the previous market location with what he's moving with: which is 3)

A cookie jar contains three types of cookies: oatmeal, chocolate chip, and sugar. 60% are chocolate chip. Half of the remaining cookies are oatmeal. If there are 9 oatmeal cookies, how many cookies are in the jar?
Answer:
15
Step-by-step explanation:
Hey there!
--------------------------
Answer:
45 cookies in the jar
Step-by-step explanation:
100% - 60% = 40%
Half of the remaining (40%) are oatmeal so half of 40% = 20%.
20% are oatmeal.
If 20% = 9,
100% = 45

I uuh need some help
Answer:
6
Step-by-step explanation:
First, find the total number for the set of four numbers. To do this, multiply 3.5 and 4. We do this because the mean is division, so we need to get back to the original amount.
3.5 x 4 = 14
Next, we need to find the other total when the mean is 4. There are 5 numbers, which tells us we had to divide the total by 5 to get 4. So, again, we want to multiply the mean, 4, and the 5 to get the total.
5 x 4 = 20
Finally, find the number we added in. To do this, we subtract the two totals.
20 - 14 = 6

The number of customers at Yummy Smoothies varies throughout the day. During the lunch rush on Saturday, there were 120 customers at Yummy Smoothies. The number of customers at Yummy Smoothies during dinner time was 10 customers fewer than the number during breakfast. The number of customers at Yummy Smoothies during lunch was 3 times more than during breakfast. How many people were at Yummy Smoothies during breakfast? How many people were at Yummy Smoothies during dinner? Let d represent the number of customers at Yummy Smoothies during dinner and b represent the number of customers at Yummy Smoothies during breakfast.
Answer:
190 people
Step-by-step explanation:
At lunch, there were 120 people.
There were 3 times more people at lunch than breakfast meaning you divide 120 by 3.
120 / 3 = 40
At dinner, there were 10 people less than at breakfast.
40 - 10 = 30
Add up your numbers.
120 + 40 + 30 = 190
B = 40
L = 120
D = 30
