Answer:
y = (10 * 0.2) ^ x
Y = (2)^x
Y = 2^x + 10
6.5 hours
Step-by-step explanation:
Y is the number of people at the school who have been infected with the flu. The 10 is the initial number of infected students which is a constant so it does not change. The 0.2 is the rate of increase, or 20%. The x exponent is the number of hours so that is a changing number. Your answer is 2 to the power of the number of hours which is x. Add ten after that to get your number. to get 100 people ill, it would take about 6.5 hours.
Which graph is proportional?
Answer:
A
Step-by-step explanation:
As an estimate we are told 5miles is 8km convert 68 km to miles ?
Answer:
42.5miles
Step-by-step explanation:
68÷8= 8.5
8.5×5= 42.5 miles
we use the numbers given to us because we are finding the estimate.
our estimate is correct because 68km= 42.3 miles
Answer:
The exact answer is 42.25 miles
Step-by-step explanation:
divide 68 by 8 and get 8.5. Multiply 8.5 by the 5 so you get 42.5. Which is a super close estimate.

SOMEONE HELP!!!! EASY POINTS!!!! ANSWER ALL!!!
Answer:
1. 20x+8=48 2. x=2 3. the area of the square is 144units^2
Step-by-step explanation:
assuming its a perfect 4 sides square the total perimeter would be 5x + 2 units multiplied by 4 = the perimeter so 20x+8 = 48
20x+8=48
subtract 8 from both sides
20x=40
divide 20
x = 2 units
For area plug x back into 5x+2 and you will get 12 units for one side and all sides here should be 12 units so multiply one side with another
12 x 12 = 144 units^2
Answer:
Well I answered in the comments, but I need points so the answers are (in order) 12, 2, and 144
Step-by-step explanation:
Since it's a square, the sides will be the same length. If the perimeter is 48, then you divide 48 by 4 and you will have 12- your answer.
For x, subtract 2 from 12 to get ten, then divide that by five to get your answer which would be 2.
If the side length is 12, you square that and 12 squared is 144.

Answer:
15. 1800
16. 18759
Step-by-step explanation:
216 * 5 = (200 + 10 + 6) * 5 = 200 * 5 + 10 * 5 + 6 *5 = 1000 + 50 +30 = 1800
6,253 * 3 = (6000 + 200 + 50 + 3) * 3 = 18000 + 600 + 150 +9 = 18600 + 150 +9 = 18750 + 9 = 18759

С. 64 л cm
OD. 24 л cm3
ILL GIVE BRAINLIST:)
Answer:
[tex]24\pi \: cm {}^{2} [/tex]
Step-by-step explanation:
The area of a cone is
[tex]\pi \times r {}^{2} + \pi \times r \times \sqrt{ {r }^{2} + {h}^{2} } [/tex]
The volume of the conical paper cup will be option (D) 24π
What is Cone?A cone is a three-dimensional geometric shape that tapers smoothly from a flat base to a point called the vertex.A cone is formed by a set of line segments, half-lines, or lines connecting a common point, the vertex, to all of the points on a base that is in a plane that does not contain the vertex.Cone is a solid or hollow object which tapers from a circular or roughly circular base to a point.What are steps to solve this problem?The steps are as follow:
Given:r = base radius = 3 cm
h = height of cone = 8 cm
V = volume of cone = (1/3)πr²h.
V = (1/3)π*3²*8.
V = 24π
So, the volume of the conical paper cup will be option (D) 24π

Dawn says -2(-3)(4) is equal to 6(4). Javier says -2(-3)(4) is equal to -2(-12). Who is right? Explain
Answer:
Both of them
Step-by-step explanation:
-2*-3 = 6
So -2(-3)(4) is equal to 6(4).
-3*4 = -12
So -2(-3)(4) is equal to -2(-12).
what is a way that i can get 3x and 2x to cancel out in this problem? i need to get - 5y = -13 and + 15y = -3 alone.
problem:
3x + 5y = -13
2x + 15y= 3
Answer:
For 3x + 5y = -13 the answer is x= -13/3 + 5y/3
and for 2x + 15y=3 the answer x= 1.5 + (-15y/2)
Step-by-step:
For 3x+5y=-13 you have to add 5y on both sides. Then you have to divide by 3 on both sides and cancel out the common factor of 3. Then you would get x= 13/3 + 5y/3.
For 2x + 15y=3 you have to subtract 15y on both sides of the equation. You should have 2x=3 + (-15y). Then divide by 2 on both sides. 3 divided by 2 is 1.5 and -15y divided by 2 is -15y/2 since 2 doesn't have the same variable. so the answer should be x= 1.5 + (-15y/2).
Sketch the graph of each linear inequality
Answer:
Step-by-step explanation:
In an inequality, sign of greater than or less than decides that the graph of the line will be a dotted line.
And sign of greater than means area above the dotted line.
Table for input output values,
x -4 0 4 6
y -3 -4 -5 -5.5
Plot these points and join them by a dotted line.
Now we shade the area above the dotted line to show the solution area of the inequality.

A borehole pumps 7,2kl of water in 1hour. How many litres does it pump in 1second.
Answer:
20 liters
Step-by-step explanation:
The computation of the number of liters does it pump in 1 second is shown below:
Since the borehole pumps 7,2 kl of water i.e. 72,000 liters in one hour
Now the number of liters in 1 second is
= 72,000 × 1 seconds ÷ 3,600 seconds
= 20 liters

Answer:
B
Step-by-step explanation:
The graph shows a turning point at x = - 1
This indicates a zero at x = - 1 with multiplicity 2
The corresponding factors are (x + 1) and (x + 1), thus
y = (x + 1)(x + 1) ← best describes the graph
Guadrilateral whose vertices are A(-2-2),B(5-2),C(4-3) and D(-3,-3)what kind of a guadrilatetal is ABCD?
Answer:
The quadrilateral ABCD is a parallelogram
Step-by-step explanation:
The vertices of the quadrilateral ABCD are;
A(-2 -2), B(5, -2), C(4, -3)and D(-3, -3)
The slope of segment [tex]\overline {AB}[/tex] = (-2 - (-2))/(5 - (-2)) = 0
The length of segment [tex]\overline {AB}[/tex] = 5 - (-2) = 7 (points having the same y-coordinates)
The slope of segment [tex]\overline {AD}[/tex] = (-3 - (-2))/(-3 - (-2)) = 1
The length of segment [tex]\overline {AD}[/tex] = √((-3 - (-2))² + (-3 - (-2))²) = √2
The slope of segment [tex]\overline {DC}[/tex] = (-3 - (-3))/(-3 - 4) = 0
The length of segment [tex]\overline {DC}[/tex] = 4 - (-3) = 7 (points having the same y-coordinates)
The slope of segment [tex]\overline {BC}[/tex] = (-3 - (-2))/(4 - 5) = 1
The length of segment [tex]\overline {AD}[/tex] = √((4 - 5)² + (-3 - (-2))²) = √2
Therefore;
The opposite sites of the quadrilateral ABCD are equal; [tex]\overline {AB}[/tex] = [tex]\overline {DC}[/tex], [tex]\overline {AD}[/tex] = [tex]\overline {BC}[/tex]
Given that the slope of a line gives the inclination of the line on a graph, we have;
The opposite sites of the quadrilateral are parallel; [tex]\overline {AB}[/tex] ║ [tex]\overline {DC}[/tex], [tex]\overline {AD}[/tex] ║ [tex]\overline {BC}[/tex]
Therefore the quadrilateral ABCD is a parallelogram because the opposite sides of the quadrilateral ABCD are parallel.
