Answer: 480 ml
The greatest amount of fizzy drink can he make is 480 ml
Step-by-step explanation:
Given;
Mixing ratio = 5 : 3
Volume of lime juice = 300ml
Volume of lemonade = 200ml
From the given ratio;
5 ml of lemon juice needs 3 ml of lemonade to make 8 ml of fizzy drink.
Assuming all the lemon juice were used;
For 300ml of lemon juice,
It'll require 300/5 × 3 ml of lemonade.
Volume of lemonade needed V2= 300/5 × 3 = 180 ml
Volume of fizzy drink = volume of lemon juice + volume of lemonade
Volume of fizzy drink = 300ml + 180ml = 480ml
The greatest amount of fizzy drink can he make is 480 ml
A frog has fallen into a pit that is 30m deep. Each day the frog climbs 3m but falls 2m at night. How many days those it takes the frog to escape
Answer:
28 days
Step-by-step explanation:
because the frog climbs 3m in the day, but falls 2m at night, it technically climbs 1m every 24 hours. this means after the 1st day, it will have climbed a total of 1m, on the second, it will have climbed a total of 2m, and so on. however, when it gets nearer to the top, that's when things start to change. after the 26th day, it will have climbed 26m. on the 27th day, it will be 27m, but then when it jumps 3m the next day, it will reach 30m total before it falls during the night and it will be able to get out of the hole.
i hope this helps! :)

you can open the parentheses right away because it is addition. so you are left with 5+z+2. you can add both 5 and 2 together, so the final result will be 7+z
the length of two parallel sides of a trapezium are 91 cm and 51 cm and the length of two other side 37 CM and 13 cm respectively determine the area of trapezium
Answer:
903 sq. cm.
Step-by-step explanation:
It is given that the length of two parallel sides of a trapezium are 91 cm and 51 cm and the length of two other side 37 CM and 13 cm respectively.
Now draw a dotted line as shown in the below figure. So, we have a triangle with sides 13 cm, 37 cm, 40cm and a parallelogram with sides 51 cm, 13 cm.
Area of parallelogram is
[tex]A_1=base\times height[/tex]
[tex]A_1=51\times 13[/tex]
[tex]A_1=663[/tex]
Using heron's formula, area of triangle is
[tex]A=\sqrt{s(s-a)(s-b)(s-c)}[/tex]
where, [tex]s=\dfrac{a+b+c}{2}[/tex].
The sides of triangle are 13cm, 37 cm, and 40 cm.
[tex]s=\dfrac{13+37+40}{2}=45[/tex]
Area of triangle is
[tex]A=\sqrt{45(45-13)(45-37)(45-40)}=240[/tex]
The area of trapezium is
[tex]A=A_1+A_2=663+240=903[/tex]
Therefore, the area of trapezium is 903 sq. cm.

Why can't you use the product of powers rule to simplify
this expression? Explain.
3^4.2^8
Answer:
You can't use this rule because the two exponents have different bases. In order to use this rule the two exponents must have the same base.
Answer:
It is because both expressions have different base value. For this question, the bases are 3 and 2 where the product rule cannot be applied. Product rule can only be used when both expressions have the same bases.

in a basket of fruits there are 9 bananas 7 mangoes 2 pineapples. What fraction of the fruits are pineapple?
Answer:
1/9
Step-by-step explanation:
9 bananas 7 mangoes 2 pineapples. = 18 pieces of fruit
Fraction of fruit that is pineapple
pineapple / total
2/18
Simplifying
1/9
Answer:
1/9
Step-by-step explanation:
To start off, add all of the known fruit amounts in order to find the total amount of fruit.
9 bananas +7 mangoes + 2 pineapples
When you do this, you find that the total fruit is 18
In order to know probability, you must divide the desirable outcome by the total possible outcomes.
The desirable outcome is pineapple. There are 2 pineapples. The total possible outcomes are 18.
2/18
You can simplify this fraction so that it becomes 1/9 by dividing the numerator and the denominator by 2

Percent Error Item Approximate value Exact value Error Absolute error Ratio Percent error Automobiles 45 48 a b a = Negative StartFraction 3 over 45 EndFraction; b = negative 6.8 percent a = Negative StartFraction 3 over 48 EndFraction; b = negative 6.25 percent a = StartFraction 3 over 48 EndFraction; b = 6.25 percent a = StartFraction 3 over 45 EndFraction; b = 6.8 percent
Answer:
a = 3.45b = 6.67%Step-by-step explanation:
Initial prediction of sales = 45 automobile
Actual amount sold = 48 automobiles
Absolute error ratio a = actual amount sold - initial prediction/initial prediction
Absolute error ratio a = 48-45/45
Absolute error ratio a = 3/45
%error = actual amount sold - initial prediction/initial prediction * 100%
% absolute error = 48-45/45 * 100
% absolute error = 3/45 * 100

The exponential function g, whose graph is given below, can be written as g(x)=a•b^x
Answer:
g(x) = [tex]8(\frac{1}{2})^x[/tex]
Step-by-step explanation:
Let the equation of the graphed exponential function is,
g(x) = [tex]a(b)^x[/tex]
Two points (0, 8) and (1, 2) lie on this graph.
For (0, 8),
g(0) = [tex]a(b)^0[/tex]
8 = a(1)
a = 8
For other point (1, 2),
g(1) = [tex]a(b)^1[/tex]
2 = ab
2 = 8b
b = [tex]\frac{2}{8}[/tex]
b = [tex]\frac{1}{4}[/tex]
Therefore, given exponential function wiil be,
g(x) = [tex]8(\frac{1}{2})^x[/tex]
Answer:
8⋅(1/4)^x

16.) The school that Lisa goes to is selling tickets to the annual talent show. On the first day of ticket sales the school sold 4 adult tickets and 5 student tickets for a total of $102. The school took in $126 on the second day by selling 7 adult tickets and 5 student tickets. What is the price of the adult and the student ticket?
Answer:
adult tickets are $8 and student tickets are $14
Step-by-step explanation:
to find the price of adult and student tickets, first look at all the given values:
a = adult tickets
s = student tickets
so: 4a + 5s = 102
and : 7a + 5s = 126
since in both equations the number of student tickets are the same, we have to find the difference of value to determine how much adult tickets are:
126-102 = 24
there are 3 more adult tickets in the equation with a total of 126, therefore:
24 / 3 = 8
that means each adult ticket is work 8 dollars.
now substitute this value:
4(8) + 5s = 102
32 + 5s = 102
you can solve this by concluding that 102- 32 is 70
that means 5(s) has to equal 70
so 70 / 5 = s
70/5 = 14
so the value of s = 14 and the value of a = 8

A player tosses a die 6 times.If gets a number 6 Atleast two times he wins 2 dollars ,otherwise he looses 1 dollar.. Find the expectation of the amount if he wins
Answer:
[tex]E(x)=-0.2101[/tex]
Step-by-step explanation:
The expected value for a discrete variable is calculated as:
[tex]E(x)=x_1*p(x_1)+x_2*p(x_2)[/tex]
Where [tex]x_1[/tex] and [tex]x_2[/tex] are the values that the variable can take and [tex]p(x_1)[/tex] and [tex]p(x_2)[/tex] are their respective probabilities.
So, a player can win 2 dollars or looses 1 dollar, it means that [tex]x_1[/tex] is equal to 2 and [tex]x_2[/tex] is equal to -1.
Then, we need to calculated the probability that the player win 2 dollars and the probability that the player loses 1 dollar.
If there are n identical and independent events with a probability p of success and a probability (1-p) of fail, the probability that a events from the n are success are equal to:
[tex]P(a)=nCa*p^a*(1-p)^{n-a}[/tex]
Where [tex]nCa=\frac{n!}{a!(n-a)!}[/tex]
So, in this case, n is number of times that the player tosses a die and p is the probability to get a 6. n is equal to 6 and p is equal to 1/6.
Therefore, the probability [tex]p(x_1)[/tex] that a player get at least two times number 6, is calculated as:
[tex]p(x_1)=P(x\geq2)=1-P(0)-P(1) \\\\P(0) =6C0*(1/6)^{0}*(5/6)^{6}=0.3349\\P(1)=6C1*(1/6)^{1}*(5/6)^{5}=0.4018\\\\p(x_1)=1-0.3349-0.4018\\p(x_1)=0.2633[/tex]
On the other hand, the probability [tex]p(x_2)[/tex] that a player don't get at least two times number 6, is calculated as:
[tex]p(x_2)=1-p(x_1)=1-0.2633=0.7367[/tex]
Finally, the expected value of the amount that the player wins is:
[tex]E(x)=x_1*p(x_1)+x_2*p(x_2)\\E(x)=2*(0.2633)+ (-1)*0.7367\\E(x)=-0.2101[/tex]
It means that he can expect to loses 0.2101 dollars.
Answer:
Expected value = -0.2101
Step-by-step explanation :
Givena discrete variable the expected value is given as:
E(x) = xp(x) + yp(y)
Where x and y are the values the variables can assume, and p(x) and p(y) are their respective probabilities.
Probability that a player gets 6 at least twice = p(x ≥ 2) = 1 - p(x≤ 2)
= 1 - p(0) - p(1)
But p(0) = 0.3349
p(1) = 0.4018
p(x ≥ 2) = 1 - 0.3349 - 0.4018
= 0.2633
p(y) = 1 - p(x)
= 1 - 0.2633
= 0.7367
Expected value = 2(0.2633) + (-1)(0.7367)
= -0.2101
A loss of $0.2101 is expected.
