Answer:
No, Barbra is wrong as cost of 1 loaf of bread is £1.50 not $1.40.
Step-by-step explanation:
Note: This question is not complete. The complete question is therefore provided before answering the question as follows:
Barbara buys 3 boxes of eggs costing £1.20 each
1 jar of mayo costing £1.80
2 loaves of bread
she pays £10 note and gets £1.60 change
Barbara works out the cost of 1 loaf of bread as £1.40.
Is she correct? You MUST show your working out.
The explanation of the answer is now given as follows:
Total cost of 3 boxes of eggs = Number of boxes of eggs bought * Price per box of egg = 3 * £1.2 = £3.60
Cost of 1 jar of mayo = £1.80
Total amount spent = Note paid - Change collected = £10 - £1.60 = £8.40
Total cost of 2 loaves of bread = Total amount spent - Total cost of 3 boxes of eggs - Cost of 1 jar of mayo = £8.40 - £3.60 - £1.80 = £3.00
Cost of 1 loaf of bread = Total cost of 2 loaves of bread / 2 = £3.00 / 2 = £1.50
Therefore, Barbra is wrong as cost of 1 loaf of bread is £1.50 not $1.40.

What is the slope of line k?
A

C

D

Step-by-step explanation:
For every increase in the x-value by 1,
the y-value decreases by -2.
(From 3 to 1 and from 1 to -1)
Hence, slope of line k
= Rise/Run = (-2)/1 = -2. (A)
Using it's formula, it is found that the slope of line k is of -2, hence option A is correct.
Given two points (x,y) on a line, the slope is given by the change in y divided by change in x.
In this problem, two of the points are: (1,3) and (2,1).
Hence, applying the division:
[tex]m = \frac{1 - 3}{2 - 1} = -\frac{2}{1} = -2[/tex]
The slope of the line is of -2, hence option A is correct.

Answer:
24 cm
Step-by-step explanation:
Since, both the Pentagons are similar. So, their corresponding sides would be in proportion.
Therefore,
[tex] \frac{4}{4x} = \frac{(x + 2)}{48} \\ \\ \frac{1}{x} = \frac{(x + 2)}{48} \\ \\ x(x + 2) = 48 \\ \\ {x}^{2} + 2x = 48 \\ \\ {x}^{2} + 2x - 48 = 0 \\ \\ {x}^{2} + 8x - 6x - 48 = 0 \\ \\ x(x + 8) - 6(x + 8) = 0 \\ \\ (x + 8)(x - 6) = 0 \\ \\ x + 8 = 0 \: \: or \: \: x - 6 = 0 \\ \\ x = - 8 \: \: or \: \: x = 6 \\ \\ \because \: x \: cannot \: be \: - ve \\ \implies \: x = 6[/tex]

Drew and Larry are working together on a jigsaw puzzle. Drew places 11 less than 3 times the number of pieces that Larry places. Drew places at least 10 pieces. How many pieces does Larry place?
Answer:
Larry places 19 puzzles
Step-by-step explanation:
Step one:
given data
let the number of puzzles Larry places be x
and let the number of puzzles Drew places be y
so
y=3x-11
Step two:
We are told that Drew places at least 10
so for x= 10
y= 3*10-11
y=30-11
y=19
Hank made 6 out of 8 foul shots ,while Nelly made 8 out of 20 foul shots (A) Who scored the most baskets? (B) Compare Hank and Nelly to determine whose son is more accurate
Answer:
(A) Hank
(B) Hank
Step-by-step explanation:
Hank made 6 out of 8 foul shots Nelly made 8 out of 20 foul shots
(A) Who scored the most baskets?
Converting the shots to decimal
Hank = 6/8 = 3/4 = 0.75
Nelly = 8/20 = 1/4 = 0.40
The person who scored the most baskets is Hank
(B) Compare Hank and Nelly to determine whose son is more accurate
Determining who is more accurate,
Hank = 6/8 = 3/4
This means out of every 4 shots, Hank scored 3
Nelly = 8/20 = 1/4
This means out of every 4 shots, Nelly scored 1
Therefore, Hank is more accurate

Practice :
1. Find a line that is parallel to f(x) = 2x +3 and passes through (0,-4).
2. Find through line that is perpendicular to f(x) = 2x+3 and passes through (0,-4)
Answer:
1)The equation of the Parallel line is 2x -y -4=0
2) The equation of the perpendicular line of the given line x+2y+8=0
Step-by-step explanation:
Step(i):-
Given function f(x) = 2x+3 and passes through (0,-4)
Let y =f(x) = 2x+3
y = 2x+3
⇒ 2x -y +3=0
The equation of the parallel line of the given line 2x - y +k =0
This line is passes through the point (0,-4)
⇒ 2 (0) -(-4)+k=0
4 +k=0
⇒ k =-4
The equation of the Parallel line is 2x -y -4=0
2)
Step(ii):-
Given function f(x) = 2x+3
Let y = 2 x + 3
2x - y +3=0
The equation of the perpendicular line bx -ay +k=0
The equation of the perpendicular line of the given line -x-2y +k =0
This line is passes through the point (0,-4)
⇒ (0) -2(-4)+k=0
8 +k=0
⇒ k =-8
The equation of the perpendicular line of the given line -x-2y -8 =0
The equation of the perpendicular line of the given line x+2y+8=0

Answer:
AD=35
Step-by-step explanation:
The difference between FJ-GH is equal to the difference between EK-FJ
Lets call this difference "D"
so
(7x+2)-(8x-7)=D
simplifying
7x+2-8X+7=D
-x+9=D
(10x-1)-(7x+2)=D
simplifying
10x-1-7x-2=D
3x-3=D
now D=D so
-x+9=3x-3
12=4x
x=3
solving each known line equation for x:
8(3)-1=17
7(3)+2=23
10(3)-1=29
The line gets longer each time by 6
AD=EK+6=35

URGENT: A grocer has 150 kg of walnuts that sell for $6 per kg. She plans to add almonds that sell for $5.30 per kg to the walnuts to make a mixture that sells for $5.50 per kg. How many kg of almonds should she add? (MUST SHOW WORK)
Answer:
let c = cashew pounds, w = walnut pounds, m = mixed pounds
Here's what we know:
c + w = m
7c + 5.5w = 6.50m
m = 35
So we now have:
c + w = 35
7c + 5.5w = 227.5
We can use substitution or elimination here. Let's try substitution in this case:
c = 35 - w
7(35 - 7) + 5.5w = 227.5
245 - 7w + 5.5w = 227.5
245 - 1.5w = 227.5
-1.5w = -17.5
w = 11 2/3
Now to solve for cashews:
c = 35 - 11 2/3
c = 23 1/3
Check:
23 1/3 * 7 + 5.5 * 11 2/3 = 227.5
163 1/3 + 64 1/6 = 227.5
163 2/6 + 64 1/6 = 227.5
227 3/6 = 227.5
227.5 = 227.5
