Sid has £5 to buy apples and bananas.
He uses his money like this:
He buys 18 apples.
Then he buys as many bananas as possible.
With his change he buys more apples.
How many apples and bananas does he buy?
(Apples=6p Each)
(Bananas= 40p Each)
Step-by-step explanation:
cost of 18 apples= 18x6p= 108p
£5-108p= x (will let it be x since i do not know the conversion)
maximum number of banana he can buy= x divide by 40p (rounded down to smallest whole number)= b
The change he have= x-(40×b) = y
apples bought with change= y divide by 6p= a
do the working above to find value for a and b, add a to the 18 apples bought initially and b is number of banana
function or not a function?
Answer:
Not a function
Step-by-step explanation:
You draw lines going down the graph and if any of those lines have more than one point then it is not a function.

given logx 2=p and logx 7=q , express log7 4x² in terms of p and q
Answer:
[2(p + 1)]/q
Step-by-step explanation:
logx 2 = p
logx 7 = q
log7 4x² = log7 (2x)²
= (logx (2x)²)/(logx 7)
= (2 logx 2x)/(logx 7)
= (2 logx 2 + 2 logx x)/(logx 7)
= (2p + 2)/q
= [2(p + 1)]/q

You bought 8 bags of dog food and 2 boxes of dog treats for a total of $135. Your friend bought 6 bags of dog food and 4 boxes of dog treats for a total of $110. Each bag of dog food costs the same amount. Each box of dog treats costs the same amount. Write a system of equations, then find the cost of one bag of dog food.
Answer:
8f + 2t = $135 - - (1)
6f + 4t = $110 - - (2)
$16
Step-by-step explanation:
Given that:
f = dog food
t = dog treat
8f + 2t = $135 - - (1)
6f + 4t = $110 - - (2)
From (1)
4f + t = 67.5
t = 67.5 - 4f
Put t = 67.5 - 4f in (2)
6f + 4(67.5 - 4f)= 110
6f + 270 - 16f = 110
-10f = 110 - 270
-10f = - 160
f = 16
One bag of dog food = $16

During a field trip, 60 students are put into equal-sized groups. Describe two ways to interpret 60÷5 60 ÷ 5 in this context. Find the quotient. Explain what the quotient would mean in each of the two interpretations you described. Consider the division expression 712÷2 7 1 2 ÷ 2 . Select all multiplication equations that correspond to this division expression. 2⋅?=712 2 ⋅ ? = 7 1 2 712⋅?=2 7 1 2 ⋅ ? = 2 2⋅712=? 2 ⋅ 7 1 2 = ? ?⋅712=2 ? ⋅ 7 1 2 = 2 ?⋅2=712
The second question:
Consider the division expression [tex]7\frac{1}{2} / 2[/tex]. Select all multiplication equations that correspond to this division expression.
[tex]2 * ? = 7\frac{1}{2}[/tex] [tex]7\frac{1}{2} * ?= 2[/tex] [tex]? * 2 = 7\frac{1}{2}[/tex]
[tex]2* 7\frac{1}{2} = ?[/tex] [tex]? * 7\frac{1}{2} = 2[/tex]
Answer:
1. See Explanation
2. [tex]2 * ? = 7\frac{1}{2}[/tex] and [tex]? * 2 = 7\frac{1}{2}[/tex]
Step-by-step explanation:
Solving (a):
Given
[tex]Students = 60[/tex]
[tex]Group = Equal\ Sized[/tex]
Required
Interpret [tex]\frac{60}{5}[/tex] in 2 ways
Interpretation 1: Number of groups if there are 5 students in each
Interpretation 2: Number of students in each group if there are 5 groups
Solving the quotient
[tex]Quotient = \frac{60}{5}[/tex]
[tex]Quotient = 12[/tex]
For Interpretation 1:
The quotient means: 12 groups
For Interpretation 2:
The quotient means: 12 students
Solving (b):
Given
[tex]7\frac{1}{2} / 2[/tex]
Required
Select all equivalent multiplication equations
Let ? be the quotient of t [tex]7\frac{1}{2} / 2[/tex]
So, we have:
[tex]7\frac{1}{2}/2 = ?[/tex]
Multiply through by 2
[tex]2 * 7\frac{1}{2}/2 = ? * 2[/tex]
[tex]7\frac{1}{2} = ? * 2[/tex]
Rewrite as:
[tex]? * 2 = 7\frac{1}{2}[/tex] --- This is 1 equivalent expression
Apply commutative law of addition:
[tex]2 * ? = 7\frac{1}{2}[/tex] --- This is another equivalent expression

1. Which ratio is equivalent to 3:9?
24.54
18:54
36.81
Both 9/3 and 54/18 come out to 3, so your answer is:
18:54
Answer:
18:54
Step-by-step explanation:
We have to simplify these ratios.
If the most simplified form of the ratios are equal, they are equivalent
3:9
24:54
18:54
Same ratio as 3:9, so 18:54 is equivalent to 3:9
36:81
A scientist was in a submarine below sea level, studying ocean life. Over the next ten minutes, she descended 41.6 feet. How many feet had she been below sea level, if she was 102 feet below sea level after she descended?
Answer:
143.6 below sea level
Step-by-step explanation:
Given that:
Initial altitude of the submarine = 102 feet below sea level
Distance descended over the next 10 minutes = 41.6 minutes
To find:
The altitude below sea level after she descended ?
Solution:
To find the resultant altitude below sea level, we need to subtract the altitude descended in the next ten minutes from the initial altitude.
We are doing so because scientist has further descended i.e. gone below the water.
Initial altitude is also in negative sign because of the fact that it is below sea level.
Therefore, the answer can be found as:
-102 - 41.6 = - 143.6
OR
143.6 below sea level is the answer.

What is the value of KL
Answer:
40.5
Step-by-step explanation:
Since the centroid (the point of concurrency of the sides of a triangle) divides the 3 medians into the ratios from the point to the centroid to the centroid to the side into the ratio of 2:1. To find PK divide 27 by 2
27/2=13.5
Then add 27 and 13.5 to get KL
27+13.5=40.5

The length of a rectangle is 5 more than the side of a square, and the width of the rectangle is 5 less than the side of the square. If the area of he square is 45, what is the area of the rectangle
Answer:
20
Step-by-step explanation:
Given :
Length = l
Width = w
Area of square = 45
Let side of square = x
Area of square = x²
45 = x²
√45 = x
l of rectangle = x + 5 = √45 + 5
w of rectangle = x -5 = √45 -5
Area of rectangle= l * w
Area = (√45 + 5) * (√45 - 5)
Area = 45 - 5√45 + 5√45 -25
Area = 45 -25
Area of rectangle = 20

1) Supposed that you have an account with the overdraft
protection. Your account balance is $40.00, you spend
$85.00 at a grocery stores. The bank charge you $30.00
every time you overdraft the account. What is your
account balance after the overdraft and the bank fee?
A) -$60.00
B) -$75.00
C) -$80.00
D) -$70.00
Answer: B) -$75.00
========================================================
Explanation:
Draw a vertical number line. Plot 40 on this line. Then move down 85 units to arrive at 40-85 = -45. The negative indicates that you're in debt.
Then move down another 30 due to the overdraft fee and we have -45-30 = -75 as the bank balance.
-------------------
Put another way:
Start at $40. If you spend $40, then your balance is $0. You need to spend another $45 to get all of the groceries (since the grocery bill is 40+45 = 85 dollars). That's where the -45 comes from, to indicate you're 45 dollars in debt. This is before the overdraft fee kicks in. Adding on that fee gets a total debt of 45+30 = 75 dollars. So that's why the final balance is -75 dollars.
