Margaret has some cows. The cows produce an average total of 11.9
litres of milk per day for 290 days. Margaret sells the milk in 0.5 litre
bottles. Work out an estimate for the total number of bottles that
Margaret will be able to fill with the milk.
Answer:
6902
Step-by-step explanation:
Total milk produced in 290 days = 11.9 x 290 = 3451 litres
If 1 bottle has a capacity of 0.5l, the number of bottles needed = 3451 / 0.5 = 6902 bottles
PLS help me!!! (EASY) (CORRECT Answer GETS BRAINLIEST + 16 points!!)
Answer:
y = 2x + 2
Step-by-step explanation:
First you want to find the slope of the line that these coordinates make. To do this, use the slope formula: (y₂ - y₁) / (x₂ - x₁). I will use the first and last points.
(0, 2) & (6, 14)
Plug in these values:
(14 - 2) / (6 - 0)
Simplify the parentheses.
= (12) / (6)
Simplify the fraction.
12/6
= 2
This is your slope.
Now plug this into the standard slope-intercept equation: y = mx + b
y = 2x + b
b is the y-intercept, or the value of y when x = 0. If y=we look at the table, we can see that when x = 0, y = 2.
Therefore, our b-value is 2.
Plug this into our equation.
y = 2x + 2

Step-by-step explanation:
A radio disc jockey has 8 songs on this upcoming hour's playlist: 2 are rock songs, 4 are reggae songs, and 2 are country songs. The disc jockey randomly chooses the first song to play, and then she randomly chooses the second song from the remaining ones. What is the probability that both songs are reggae songs? Write your answer as a fraction in simplest form.
Answer:
[tex] \displaystyle \frac{1}{28} [/tex]
Step-by-step explanation:
we are given 8 songs
2 are rock. 4 are reggae, 2 are country
we want to figure out the probability of getting both reggae songs
notice that, they aren't replacing thus it's an independent probability
recall that,
[tex] \displaystyle \rm P(A \: \text{and} \: B) = P(A) \times P(B \mid A)[/tex]
P(A) represents the chance of getting our subject first time and P(B|A) represents the chance of getting the same subject second time
let's figure out P(A)
we have 2 reggae songs
and total 8 songs
therefore
[tex] \displaystyle\rm P(A) = \frac{2}{8} = \frac{1}{4} [/tex]
let's figure out P(B|A)
since we took a reggae song before now we have only a reggae song
and total 8-1=7
therefore
[tex] \displaystyle \rm P(B\mid A) = \frac{1}{7} [/tex]
Altogether
[tex] \displaystyle \rm P(A \: \text{and} \: B) = \frac{1}{4} \times \frac{1}{7} [/tex]
simplify multiplication:
[tex] \displaystyle \rm P(A \: \text{and} \: B) = \frac{1}{28} [/tex]
And we are done!

(Answer is not -3)
Answer:
Look below.
Step-by-step explanation:
K(x)=x^2 isnt graphed but P(x)=x^2+n is. We could use this information to figure out what n is. In a quadratic function we always have the same points unless we are transforming it.
X Y
2 4
1 1
0 0
-1 1
-2 4
If we compare what the points were in the parent function to what is shown now we could see that the graph went down 6. From this information we can conclude that n must be -6.

Three friends were playing a game of marbles. At the end of the game, Marcy had 25% of the marbles, Roger had21of the marbles, and Ann had the rest of the marbles. If there were 100marbles altogether, how many marbles did Ann have at the end of the game
Answer:
54
Step-by-step explanation:
total no. of marbles=100
no. of marbles Marcy had
=25% of 100
=25/100×100
=25
no. of marbles Roger had=21
Let the no. of marbles Ann had=x.
So, 25+21+x=100
46+x=100
x=100-46=54
Therefore, Ann had 54 marbles at the end of the game.

SOLVE THESE TWO FOR BRAINLY PLSSSS!!!!!!!!
Answer: 1) D
2) A
Step-by-step explanation: plz mark me brainliest
Answer:
1) C) 2) B)
Step-by-step explanation:
First one is just times them together get 12root(a^2b^2) = 12ab.
Second question, you use equation 1 to minus equation 2 get 2x = 6, then x = 3, then substitute it into either equation, for example the first one get -7*3 + 5y = 24, then solve for y, can get y = 9, so B) is correct answer.

R
Towns P, Q and Rare connected by roads PQ, PR and QR.
PR is 15 km longer than PQ.
QR is three times as long as PR.
The total length of the three roads is 245 km
Work out the length of PQ.
Use x as the unknown in any working.
Your final line must say, PQ = ...
Pa
Answer: 37 km
Step-by-step explanation:
Given
The total length of the three roads is 245 km
Suppose the length of PQ is [tex]x\ km[/tex]
According to question
The Length of PR is [tex]x+15[/tex]
The length of QR is [tex]3(x+15)[/tex]
The Sum of PQ, PR, and QR is
[tex]\Rightarrow x+x+15+3(x+15)=245\\\Rightarrow 5x+60=245\\\Rightarrow 5x=185\\\Rightarrow x=37 km[/tex]
length of PQ=37 km
In 2004 kyle was 8 years old . In 2006 kyle was was four year older than his cousin albert. a.how old was albert in 2004. b. in what year was albert born
Answer:
Albert was born in the year 2000!
Step-by-step explanation:
2006 Kyle is 10
10 - 4 = 6
So, Albert was 6 years old in 2006
6 - 6 = 0
2006 - 6 = 2000
Kyle was born in the year 2000.
Answer:
A) 4 years old
B) 2000
Step-by-step explanation:
A) 2004 Kyle was 8 years old. Two years pass which makes Kyle 10. Kyle is 4 years older than his cousin 10-4 equal 6. Albert was 6 in 2006. 6-2 equal 4
B) Albert is 6 (2006) which means he was born in 2000.

Step-by-step explanation:
Sin A = [tex]\frac{opposite side}{hypotenuse}=\frac{5}{13}\\\\[/tex]
Cos A = [tex]\frac{Adjacent side}{hypotenuse}=\frac{12}{13}[/tex]
Tan A = [tex]\frac{opposite side}{adjacent side}=\frac{5}{12}[/tex]
A = tan⁻¹ (5/12) = 22.61°
Answer:
Step-by-step explanation:
a) Sin A = opposite/hypothenuse
Sin A = 5/13 ≈ 0.3846..
b) Cos A = adjacent/hypothenus
Cos A = 12/13 ≈ 0.9230..
c) Tan A = opposite/adjacent
Tan A = 5/12 ≈ 0.4166..
d) we will use the inverse Sine function
< A = sin^-1(5/13)
< A = sin^-1(0.3846) ≈ 22.62°
P.S. You can use any of the three inverse functions to find the angle: sin^-1 | cos^-1 | tan^-1
A lake near the Arctic Circle is covered by a 2-meter-thick sheet of ice during the cold winter months. When spring arrives, the warm air gradually melts the ice, causing its thickness to decrease at a constant rate. After 3 weeks, the sheet is only 1.25, point, 25 meters thick.
Let y represent the ice sheet's thickness (in meters) after x weeks.

Answer: 16p^8q^4r^8 The yellow one
Step-by-step explanation:
Step 1: Use Multiplication Distributive Property: (xy)^a = x^a y^a. So 4^2p^2(q^3)(r^4)^2
Step 2: Simplify 4^2 to 16. So 16p^2(q^3)^2(r^4)^2
Step 3: Use Power Rule: (x^a)^b=x^ab. So 16p^2q^6(r^4)^2
Step 4: Use Power Rule: (x^a)^b=x^ab. So the answer is 16p^2q^6r^8. The yellow one
