Step-by-step explanation:
Kim makes spiced tea from her mother's recipe. The recipe calls for 2 %
cups of sugar for each cup of tea. If she has only 4 cup of tea, how much
sugar should Kim use?
Using simple mathematical operations, we know that 8% of sugar is used in 4 cups.
What exactly are mathematical operations?An operation in mathematics transforms zero or more input values into precisely defined output values.The number of operands has an impact on the arity of the operation.A mathematical operation is a procedure.The mathematical operations of addition, subtraction, multiplication, division, and finding the root are a few examples.So, % of sugar used in 4 cups:
% of sugar per cup is 2%.The number of cups she had is 4.So, % of sugar Kim used:
2 × 4 = 8%Therefore, using simple mathematical operations, we know that 8% of sugar is used in 4 cups.

ANSWER PLEASE!!!!!!!!!
Answer:
A. True
B. False
C.True
D. True
E. Sometimes true
F. False
G. True
H. Sometimes true.
Explanation:
If I got it wrong, I will try better next time.
Answer:
A is always true, B is false, C is always true, D is sometimes true, E is always true, F is always true, G is always true, H is sometimes true.
Step-by-step explanation:
A: Anything greater than (>) 0 is positive. X is greater than zero.
B: X < 0 is false because X CANNOT be less than 0. It is a positive integer, meaning it has to be greater than 0.
C: X has to be greater than 0, so it has to be greater than -5 since -5 is less than 0.
D: 1 is a positive integer. We don't know what specific integer X represents. It could be 1, it could be greater than 1. It's sometimes true.
E: Any integer greater than or equal to 1 (≥) is a positive integer. X is a positive integer, so this is always true.
F: 0 is not a positive integer, so X cannot equal 0 (≠).
G: X has to be greater than 0 to be a positive integer, so it cannot equal -1 (≠) since -1 is less than 0.
H: The specific value of X is not stated, so it could be 5, it could be another positive integer. This is sometimes true.

Answer:
1.: 3 times 2.: 1.65 times 3.: 3.5 timesStep-by-step explanation:
1. 200%A = 2A
B is 200% more than A means:
B = A + 200%A = A + 2A = 3A
2. 65%F = 0.65F
D is 65% more than F means:
D = F + 65%F = F + 0.65F = 1.65F
3. 250%T = 2.5T
Y is 250% more than T means:
Y = T + 250%T = T + 2.5T = 3.5T

Hina drives first 120 km in 2 hrs and next 180 km in next 4 hrs. What is her
average speed for the entire trip in km per hour?
step by step explanation plz
Given ,
Distance travelled in first 2 hrs = 120 kmDistance travelled in next 4 hrs = 180 kmWe need to find
Average speedFirstly finding speed
• Speed in first 2 hrs = 120/2 = 60km/h
• Speed in next 4 hrs = 180/4 = 45 km/h
As we know that ,
Average speed = 2V₁V₂/V₁ + V₂Substituting known values we have ,
⇒ Average speed = 2 ( 60 ) ( 45 ) / 60 + 45
⇒ Average speed = 2(60)(45)/105
⇒ Average speed = 5400/105
⇒ Average speed = 51.42 km/h

Answer:
The solution to the system of equations be:
[tex]y=-3,\:x=2[/tex]
Step-by-step explanation:
Given the system of equations
[tex]\begin{bmatrix}y=3x-9\\ y=-2x+1\end{bmatrix}[/tex]
Let us solve the system by the elimination method
[tex]\begin{bmatrix}y=3x-9\\ y=-2x+1\end{bmatrix}[/tex]
Arrange equation variables for elimination
[tex]\begin{bmatrix}y-3x=-9\\ y+2x=1\end{bmatrix}[/tex]
subtracting the equations
[tex]y+2x=1[/tex]
[tex]-[/tex]
[tex]\underline{y-3x=-9}[/tex]
[tex]5x=10[/tex]
so the system of equations becomes
[tex]\begin{bmatrix}y-3x=-9\\ 5x=10\end{bmatrix}[/tex]
solve 5x for x
[tex]5x=10[/tex]
Divide both sides by 5
[tex]\frac{5x}{5}=\frac{10}{5}[/tex]
[tex]x = 2[/tex]
[tex]\mathrm{For\:}y-3x=-9\mathrm{\:plug\:in\:}x=2[/tex]
[tex]y-3\cdot \:2=-9[/tex]
[tex]y-6=-9[/tex]
Add 6 to both sides
[tex]y-6+6=-9+6[/tex]
[tex]y=-3[/tex]
Therefore, the solution to the system of equations be:
[tex]y=-3,\:x=2[/tex]

A large university accepts 40% of the students who apply. Of the students the university accepts, 25% actually enroll. If 20,000 students apply, how many actually enroll? I’ll give BRAINLEST and free art
20000 = 100% so we need to find 1% first so we can find the 40% that will be accepted
20000 : 100 = 200 (that's 1%)
to find 40% we multiply 200×40= 8000 people accepted
we need to find the 25% of those 8000 so again we divide by 100
8000 : 100 = 80
80 × 25 = 2000 people
hopefully it's correct good luck

a cone with radius of 3 feet and a height of 5 feet is placed on top of a cylinder as shown find the volume of the total figure in terms
Answer: Volume of the cone = 47.12 cubic feet.
Step-by-step explanation:
You didn't finish the question so Idid the best with what I had, you also didn't include the image that I think was supposed to be included.
To solve for the full volume including the cylinder, use the cylinder's volume formula.
Volume of a cylinder = height (pi) (r^2) and then add it to the 47.12.
Volume of a cone is pi(r^2)(h/3)
plug and chug!
h stands for height and r stands for radius.

2..When would the answer to 3+x be locaded to the right of 3?
3..When would the answer to 3+x be locaded to the left of 3?
Answer:
1. 10
2. if x was positive
3. if x was negative
Step-by-step explanation:
1. he starts on -2. so -2 + 12 is 10, so he would be on the space number 10.
2. if he moved to the right, it would mean you added something to 3. so, if x was positive, then it would move to the right.
3. if he moved to the left, it would mean that you subtracted something from 3. so, if x was negative, then it would move to the left.
