Answer:
61.6%
Step-by-step explanation:
We know that the tank contains 250 litres and that 96 litres are used. We are trying to find the percentage of the leftover quantity.
First, we need to subtract 250 from 96 litres to get the quantity that is left in the tank in litres. 250-96=154.
Then we need to find the percentage. To find a percentage we need to divide the total minus and the used amount by the total amount and then multiple the whole thing by 100. So in our case, that would be 250-96=154/250*100. Or 154/250*100.
Thus the answer is 61.6%.
Answer:
Step-by-step explanation:
Quantity left in the tank = 250 - 96 = 154 litres
Percentage = [tex]\frac{154}{250}*100\\[/tex]
= 0.616 * 100
= 61.6 %

x > 0
Greater than is represented by a open circle with an arrow pointing right. Because x is greater than 0, the point must be on 0.
Hope it helps <3
Answer:
C
Step-by-step explanation:
The inequality is x+2 > 2
x+2 >2 substract 2 from each side x+2-2 > 2-2x > 0x > 0 means that x is positive
so the graph must start from 0 and then should grow towrd the positive value
since we have x > 0 then 0 should be excluded
the graph that fits our solution is c where 0 is excluded
does the equation y = 4(5.6)^x represent exponential decay or exponential growth?
Answer:
growth
Step-by-step explanation:
Exponential equations are in the form
y = a * b^x
a is the initial value
b is the growth or decay
b>1 is growth b-1 rate of growth
b <1 decay 1-b rate of decay
y = 4(5.6)^x
5.6 is greater than 1 so it is growth

On Friday, Mica has $22.50 in her bank account. Mica goes to the market to get groceries for the week and ends up spending more than planned. When Mica checks her account, she now has a balance of $-48.15. How much money did Mica spend at the market?
Answer: $70.65
Step-by-step explanation:
From the question, we are informed that Mica has $22.50 in her bank account and then she goes to the market to get groceries for the week and ends up spending more than planned. She later checks her account and found out that she now has a balance of $-48.15.
To get the amount of money that Mica spent at the market, we subtract her balance from the opening balance she had in her bank account. This will be:
= $22.50 - (-$48.15)
= $22.50 + $48.15
= $70.65
Mics spent $70.65 at the market.
You are getting on an elevator that is already filled with several people. You wonder if your weight will put the elevator over the maximum weight limit. You know that your weight is 132 pounds. In the equation below, p is the weight of all the people already on the elevator, and t is the total weight inside the elevator after you get on. The relationship between these two variables can be expressed by the following equation: t=p+132. What is the dependent variable?
A.The total weight inside the elevator after you get on.
B.The weight of all the people already on the elevator.
Answer:
A
Step-by-step explanation:
T is the dependent variable
a dependent variable means it depends on something so if a number changes it will change the end result for T.
T is dependent on P since if the weight on the elevator changes the total weight will change. That is what makes it dependent.
Answer:
They are both dependent variables.

The upper-left coordinates on a rectangle are (-5, 6), and the upper-right coordinates are (-2, 6). The rectangle has a perimeter of 16 units. Draw the rectangle on the coordinate plane below.
Answer:
Step-by-step explanation:
Given the upper-left coordinates on a rectangle as (-5, 6), and the upper-right coordinates as (-2, 6), the distance between the two coordinates will be equal to the length of one side of the rectangle. Using the formula for calculating the distance between two points as shown;
D = √(x2-x1)²+(y2-y1)²
The the upper left coordinates be A (-5, 6) and the upper right coordinates be B(-2, 6).
AB = √(-2-(-5))²+(6-6)²
AB = √(-2+5)²
AB = √3²
AB = 3 units = Breadth of the rectangle
Give the perimeter of the rectangle to be 16 units, we can get the length of the rectangle using the formula;
Perimeter of a rectangle = 2(L+B)
16 = 2(3+L)
16 = 6+2L
10 = 2L
L = 5units
The length of the triangle is 5units

Answer:
t =5
g = 15
Step-by-step explanation:
t = tennis balls
g = golf balls
70 = 5t+3g
85 = 2t+5g
Multiply the first equation by -2
-2(70 = 5t+3g)
-140 = -10t -6g
Multiply the second equation by 5
5(85 = 2t+5g)
425 = 10t + 25g
Add these new equation together to eliminate t
-140 = -10t -6g
425 = 10t + 25g
-------------------------------
285=0t+19g
Divide by 19
285/19 = g
15 = g
Now find t
85 = 2t+5g
85 = 2t +5(15)
85 = 2t + 75
10= 2t
t =5
Let the cost of a can of tennis balls be $x and that of a sleeve of golf balls be $y.
5x + 3y = 70
2x + 5y = 85
(5x + 3y) x 2 = 70 x 2
10x + 6y = 140
(2x + 5y) x 5 = 85 x 5
10x + 25y = 425
10x + 25y -10x - 6y = 425 - 140
19y = 285
y = 15
2x + 5y = 85
2x + 75 = 85
2x = 10
x = 5
Therefore the cost of a sleeve of golf balls is $15 and that of a can of tennis balls is $5.
Kevin cuts lawns during the summer months. He charges $10 plus $5 per hour. The algebraic model is C = 5h + 10, where C represents the total cost and h represents the hours worked. Use pencil and paper to create a table of values for hours worked from 1 to 5, incrementing h by 1 in each row.
Answer:
1 hour : 15 dollars
2 hours: 20 dollars
3 hours: 25 dollars
4 hours: 30 dollars
5 hours: 35 dollars
Step-by-step explanation:
Substitute the hour number in for h and solve. for example, if you were trying to find 5 hours, you would produce the equation c = 5(5) + 10. once you solve that you get c = 25 + 10 which is also c = 35.
What is g(x)?
A. g(x) = -2
B. g(x) = -x
C. g(x) = -|x|
D. g(x) = -x^2
Answer:
A. g(x) = -2^x.
Step-by-step explanation:
If g(x) = -2, it would be a straight line running horizontally.
If g(x) = -x, it would be a linear equation.
If g(x) = -|x|, it would be an absolute value function, which is a graph in a v-shape.
So, the remaining answer is that A. g(x) = -2^x.

A jar consists of blue, red and green marbles. The probability of each of them is 2/7 , 3/k and 5/2k. Find the value of k.
Answer:
k = 77/10
Step-by-step explanation:
The jar consist of blue, red and green marbles . The probability of each of them can be described as follows.
probability of blue marbles = 2/7
probability of red marbles = 3/k
probability of green marbles = 5/2k
The sum of the individual probability is equals to 1. Therefore,
2/7 + 3/k + 5/2k = 1
collect like terms
(6 + 5)/2k = 1 - 2/7
11/2k =(7 - 2) /7
11/2k = 5/7
cross multiply
10k = 77
divide both sides by 10
k = 77/10

This is a cross-sectional view of candy bar ABC. A candy company wants to create a cylindrical container for candy bar ABC so that it is circumscribed about the candy bar. If segment AD = 4 cm, what is the smallest diameter of wrapper that will fit the candy bar? Triangle ABC in which point E is between points A and B, point D is between points A and C, point F is between points B and C, segments AE and EB are congruent, segments BF and FC are congruent, and angles AED, ABF, and DFC are right angles.
Answer:
8 cm
Step-by-step explanation:
When a right triangle is circumscribed in a circle, the diameter is the hypotenuse AC.
Therefore, the smallest diameter of the wrapper will be that of the circle whose diameter has endpoints of A and C.
From the diagram:
AE=DFED=FCTherefore, Triangle AED is congruent to Triangle DFC and in fact AD=DC.
Given: AD =4 cm
Therefore, the smallest diameter
AC=AD+DC
=4+4
=8 cm
The right triangular prism has a volume of 1,152 cm3. A right triangular prism has a volume of 1,152 centimeters cubed. The triangular bases have 2 sides with lengths of 12 centimeters. The hypotenuse length is not given. The height of the prism is x centimeters. What is the value of x, the height of the prism? 6 8 12 16
Answer:
16 cm
Step-by-step explanation:
A "right" prism is one that has the planes of the lateral faces perpendicular to the plane of the base. Here, we assume your "right triangular prism" is one that has a right triangle as a base, because you mention the "hypotenuse."
The area of the base is ...
A = (1/2)bh = (1/2)(12 cm)(12 cm) = 72 cm²
The volume of the prism is ...
V = Bh . . . . where B represents the area of the base
Filling in the numbers, we have ...
1152 cm³ = 72 cm²×h
h = (1152/72) cm = 16 cm
The height of the prism is 16 cm.
