Mick and Jackie buy a large sandwich to share. They each eat 2/5 of the sandwich.
How much of the sandwich is remaining?
Show your work.
Answer:
1/5 is remaining
Step-by-step explanation:
if there is two people each eating 2/5 we would just multiply 2/5 by 2 and get 4/5 then we would subtract 4/5 from 1 and get 1/5
Answer:
1/5
Step-by-step explanation:
Sandwich eaten by Mick and Jackie = [tex]\frac{2}{5}+\frac{2}{5}\\\\[/tex]
= [tex]\frac{2+2}{5}=\frac{4}{5}[/tex]
Remaining sandwich = 1/5

-6 + (-7) = adding negative numbers
Answer:
Step-by-step explanation:
Adding 2 negative numbers is like subtracting. You do -6 - 7. Negative 7 is literally - 7. -6 -7 = -13
Answer:
-6 + (-7) = -13
How do you find the vertex
Parabolas always have a lowest point (or a highest point, if the parabola is upside-down). This point, where the parabola changes direction, is called the "vertex". If the quadratic is written in the form y = a(x – h)2 + k, then the vertex is the point (h, k).

Answer:
l and k are both 70
Step-by-step explanation:
l and k are both the same angle.
130+90= 220
360-220=140
140/2=70
therefore l and k are both 70
Which sequence is an example of an arithmetic sequence
Answer:
Only the third sequence is arithmetic
Step-by-step explanation:
If the sequence has a common difference, then it is arithmetic. To find the common difference, substract a term from the next term.
First sequence:
10 - 20 = -10 5 - 10 = -5 The differences are not the same, so the sequence is NOT arithmetic
Second sequence:
-6 - (-3) = -3 -18 - (-6) = -12 The differences are not the same, so the sequence is NOT arithmetic
Third sequence:
10 - 5 = 5 15 - 10 = 5 20 - 15 = 5 The differences are the same, so the sequence is arithmetic
Fourth sequence:
10 - 5 = 5 20 - 10 = 10 The differences are not the same, so the sequence is NOT arithmetic
what’s the answer ????
Answer:
Answer is 4/25
Step-by-step explanation:
0.16*100 = 16 which would allow us to say 16/100
now you can divide 16 and 100 by 4 which would be
16/4 = 4 and 100/4= 25
therefore the answer is 4/25
2. If 1/2 of a gallon of paint covers 1/8 of a wall, how much paint is needed to cover the entire wall?
A) 8 2/3 gallons
B) 8 1/3 gallons
C) 3 gallons
D) 2 gallons
Please help !
Answer: 4 gallons.
Step-by-step explanation:
With this equation, we can use the ratio 1/2 : 1/8. For every 1/2 gallon of paint, 1/8 of a wall is painted.
If 1/2 gallons covers 1/8 of a wall, then we need 8 of the 1/2 gallons to cover the whole wall. We canrepresent this by multiplying 8 and 1/2.
8 x 1/2 = 4.
Because of this, 4 gallons of paint are needed to cover he entire wall.
(Quick note: I don't know why, but the answer choices seem kind of weird. But the answer is 4 :])

Water flows through a pipe at a rate of 89 quarts per hour. Express this rate of flow
in cubic meters per month. Round your answer to the nearest tenth.
Answer:
60.6 on delta math
Step-by-step explanation:
The rate of the flow will be 1.12 x 10⁻⁴ cubic meters per meter.
What is the rate of flow?The rate of the flow of the fluid is defined as the volume of the fluid through a confined space or cross-section in a unit of time. The unit of the rate of flow is gallons per minute or cubic meter per minute.
Given that water flows through a pipe at a rate of 89 quarts per hour the value of the rate of flow in cubic meters per month will be calculated as below:-
1 quartz = ( 1 / 1056.688) cubic meters
1 quartz = ( 89 / 1056.688)
1 quartz = 0.08 cubic meters
1 quartz per hour = 0.08 / ( 24 x 30) cubic meters per month
1 quartz per hour =1.12 x 10⁻⁴ cubic meters per month
Therefore, the rate of the flow will be 1.12 x 10⁻⁴ cubic meters per meter.

Constructed Response you have an economic decision to make. You have $50.00 to spend. Should you purchase sports equipment to use at home, a ticket to attend a professional sporting event, or sports memorabilia for your football collection ?
Answer:
Step-by-step explanation:
From a business standpoint, I think the smartest decision would be either the sports equipment or the memorabilia. Each has pros and cons so it depends on you. The sporting event would be the worst option as it is something that can most likely be viewed for free online. The sporting equipment will still hold monetary value and can be resold as well as providing you with other value if used properly such as being healthier and/or putting on muscle. The Sports Memorabilia would not provide real life value but may increase in monetary value and have a much higher resale value than the equipment.

Total marks: 3
Answer:
A. 48 Km.
B. 62.5 miles.
Step-by-step explanation:
From the diagram given above, the following data were obtained:
50 miles = 80 Km
A. Converting 30 miles to kilometres.
50 miles = 80 Km
Therefore,
30 miles = 30 miles × 80 Km / 50 miles
30 miles = 48 Km
Thus, 30 miles is equivalent to 48 Km.
B. Converting 100 km to miles.
80 Km = 50 miles
Therefore,
100 Km = 100 Km × 50 miles / 80 Km
100 Km = 62.5 miles
Thus, 100 Km is equivalent to 62.5 miles.

What is the equation for an arithmetic sequence with a first term of 5 and a second term of 2? (5 points) an = 5 − 2(n − 1) an = 5 + 2(n − 1) an = 5 − 3(n − 1) an = 5 + 3(n − 1)
Answer:
an = 5 − 3(n − 1)
Step-by-step explanation:
First term,a = 5
Second term = 2
Common difference,d = 2 - 5 = -3
nth term = a + d(n - 1)
= 5 -3(n - 1)
Check
When n = 2
2nd term = 5 - 3(2 - 1)
= 5 - 3(1)
=5 - 3
= 2
2nd term = 2

Jamie wants to sell popcorn for her local fundraiser. Each bag of popcom costs $5 and her grandmother gave her a donation of $18. How many bags of
popcom would she have to sell to meet her goal of raising $100? Which equation matches the situation?
Answer:
17, 100 - 18 = 82 which would be for me 5 because then it is divisible by 5 so 85 divided by 5 = 17 to completely finish her goal she would need which is a $100.

Solve the system by substitution
10x=y
2x+y=-24
Answer: x=-2
Y= -20
Step-by-step explanation
You replace the y in the second equation with 10x. This is because it says 10x=y
2x+10x=12x so you put that
12x=-24
To get x by its self you divide by 12.
-24 divided by 12 is -2.
Now you plug in -2 to either equation as y. I chose the first one because it's easier.
10(-2)=y
-20=y
