The Mayflower started with 150 passengers. It lost 60% due to illness. How many people remained?
Answer:
90 people.
Step-by-step explanation:
60% can be deduced to a fraction of 6/10. If 6/10=150, then you can cross multiply 6*150 and 10*1. 900/10=90.

What is the solution to the equation shown
2/3x + 5= 1
Answer:
x=-6
Step-by-step explanation:
Subtract 5 from 1 So: 2/3x=-4
Multiply 3/2 on both sides : x=-12/2
So x = -6
Answer:
[tex]{x = -6}[/tex]
Step-by-step explanation:
Note: * = times (x)
[tex]\huge {\frac{2}{3} x + 5 = 1}\\[/tex]
Let's isolate the x We can do this via inverse operations.[tex]\frac{2}{3}x + 5 = 1\\-5 \hspace9 \hspace9 -5\\\\\frac{2}{3}x = -4\\ * 3 \hspace9 *3\\\\2x = -12[/tex]
Now that we've isolated the x, we want to simplify it. We do this so we can make x by itself as just x instead of 6x.
[tex]\frac{2x}{2} = \frac{-12}{2} \\\\\frac{2x}{2} = x\\\\\frac{-12}{2} = -6\\\\\huge\boxed {x = -6}[/tex]

Answer:
∠KNC = 99°
Step-by-step explanation:
∠JNM + ∠KNC = 180 (it is a straight line)
∠KNC = 180 - ∠JNM
∠KNC = 180 - 81
∠KNC = 99°
Answer: 99°
Step-by-step explanation: They are supplementary so 180 - 81 = 99
For every 1 litre of water used to make a medicine, 150 ml of sucrose and 600ml of saline solution are used. Express the amount of water, sucrose and saline solution needed as a ratio in its simplest form.
Quantity of water used to make a medicine :-
[tex]= \texttt{1 \: litre }[/tex]
[tex] =\texttt{ 1×1000 \: ml}[/tex]
[tex] =\texttt{\color{hotpink} 1000 \: ml}[/tex]
This quantity of water required to make a medicine = 1000 ml
Quantity of sucrose used to make a medicine = 150 ml
Quanity of saline solution used to make a medicine = 600 ml
The quantity of water to sucrose to saline solution needed to make a medicine as a ratio :-
[tex] = \texttt{1000 : 150 : 600}[/tex]
Cutting each common zero in this ratio, we get :-
[tex] = \texttt{100 : 15 : 60}[/tex]
Dividing each number in the ratio by 5, we get the ratio :-
[tex] =\texttt{ \color{hotpink}20 : 3 : 12}[/tex]
Since, the three numbers in this ratio doesn't have any common factors we can conclude that we have found out the simplest form of the ingredients needed to make the medicine .
Therefore, the ratio of water to sucrose to saline solution needed to make a medicine = 20:3:12

What is the value of x? Please provide an explanation, thanks!
Answer:
28
Step-by-step explanation:
What you do is add up 42 and 76, then you subtract that from 180, because all triangles add up to 180. the subtracted amount is what z equals. Then since its a straight line you know it adds up to 180. You add z (62) and 90 because its a right angle. then you subtract 180 by 152 to get 28.

Find the principal. Annual rate of interest = 11 \%=11%equals, 11, percent Period = 3=3equals, 3 years Total interest = 825=825equals, 825 rupees Principal ==equals rupees
Answer:
Principal = 2,500 rupees
Step-by-step explanation:
The interest or simple interest is the extra money gained on n invested amount of money yielding a certain percentage interest at a time (t) in years
The formula for simple interest is given as follows:
I = P × R × T
where:
I = interest = 825 rupees
P = principal
R = interest rate = 11% = 11/100 = 0.11
T = time = 3 years
∴ 825 = P × 0.11 × 3
825 = P × 0.33
P = 825 ÷ 0.33
P = 2,500 rupees
This means that 2,500 rupees was invested to saved to yield an interest of 825 rupees after 3 years at a rate of 11% per year
Find the next term in this
arithmetic sequence.
Answer:
[tex]\bold{-}\frac{\boxed{\bold{11}}}{\boxed{\bold{4}}}[/tex]
Step-by-step explanation:
In arithmetic sequence the terms increase by the same number (d).
So d is the difference between any pair of next and previous term.
[tex]d=-\frac14-1=-1\frac14=-\frac54[/tex]
Therefore the next term will be:
[tex]-\frac32+d=-\frac32+(-\frac54)=-\frac64-\frac54=-\frac{11}4[/tex]
1. Priya jogs at a constant speed. The relationship between her distance and time is
shown on the graph. Diego bikes at a constant speed twice as fast as Priya.
Sketch a graph showing the relationship between Diego's distance and time.
Answer:
Step-by-step explanation:
Relationship between distance the distance and time for Priya has been given in the graph.
Therefore, slope of the line on the graph will represent the speed of jog of Priya.
Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Where [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are the points lying on the line.
Since, (0, 0) and (0.4, 2) are lying on the line.
Therefore, slope or speed of the line will be,
Speed = [tex]\frac{2-0}{0.4-0}[/tex]
= 5
Now Diego bikes at a speed twice as fast as Priya,
So Diego's speed = 5×2 = 10 mile per hour
Therefore, slope of the line for Diego on graph will be,
m = 10
Line passing through origin and slope = 10 will be,
y = 10x
Points representing Diego's speed will be,
x 0 0.1 0.2 0.3 0.4 0.5
y 0 1 2 3 4 5
Now we can graph these points to get the line.
Relationship between distance the distance and time for Priya has been given in the graph.
Therefore, slope of the line on the graph will represent the speed of jog of Priya.
Slope =
Where and are the points lying on the line.
Since, (0, 0) and (0.4, 2) are lying on the line.
Therefore, slope or speed of the line will be,
Speed =

Now Diego bikes at a speed twice as fast as Priya,
So Diego's speed = 5×2 = 10 mile per hour
Therefore, slope of the line for Diego on graph will be,

Answer:
The slope of the line is 2. To find the slope I marked two points on the line, which were (-3, 0) and (-2, 2). Then I used the [tex]\frac{Rise}{Run}[/tex] technique. Moving up 2 units and to the right 1 unit, which would be represented by [tex]\frac{2}{1}[/tex].
The slope of the line graphed below would be 2.
Using the formula Rise/Run, you can solve the slope using the graph. The Rise would be equal to 2 units, with the Run being one. This means that for every 1 unit on the x-axis, there are 2 units displaced on the y-axis. Therefore, the slope would be 2/1.
