Shop A _________________ shop B £3
Any sandwich - £2.85 ___ sandwich, water crisp
A bottle of water - 60p
A bag of crisp - 85p
Answer:
£6.50, John is incorrect
Step-by-step explanation:
Number of working days = 5 = number of days meal is purchased
Total cost per meal, shop A :
£(2.85 + 0.60 + 0.85) = £4.3
Total cost for the week = 4.3 * 5 = £21.50
Total cost per meal cost Shop B = £3
Total cost for the week = 3 * 5 = £15
Difference :
£21.50 - £15 = £6.50
Hence, Amount John saves by buying from shop B is £6.50

(x+y)² + 2(x+ y)(x- y) + (x– y)²
Answer:
2x(x+y)(x-y)
Step-by-step explanation:
Given the expression;
(x+y)² + 2(x+ y)(x- y) + (x– y)²
Factorize
(x+y)² + (x+ y)(x- y) + (x+ y)(x- y) + (x– y)²
= (x+y)[x+y+(x-y)] +(x-y)[(x+y)+(x-y)]
= (x+y)(x-y)(x+y+(x-y))
= (x+y)(x-y)(x+y+x-y)
= (x+y)(x-y)(2x)
hence the expanded form is 2x(x+y)(x-y)

A pet store sold 2 birds. They sold 6 times as many turtles as they sold birds. How many turtles did they sell?
Answer:
12
Step-by-step explanation:
"6 times as many birds..." in other words 6 x 2
The number of turtles that was sold by the pet store given the number of birds sold is 12.
How many turtles are sold?
Multiplication is a mathematical operation that involves determining the product of two or more numbers. The sign used to represent multiplication is x.
Number of turtles were sold = 2 x 6 = 12

small baby answer
are 4x^5 and -13x^5 like terms ?
Answer:
yes
Step-by-step explanation:
like terms are terms that have the same variables and powers. The coefficients do not need to match. Unlike terms are two or more terms that are not like terms, i.e. they do not have the same variables or powers.

ITS SO CONFUSINGNSKDN
Answer:
y=67.7 Degrees
Step-by-step explanation:
You're given the opposite and adjacent sides to angle Y, so we use Tan to find the angle:
Tan(y)= 100/41
We then inverse tan to isolate y
y=tan^-1 100/41
y=67.7 Degrees
Note: Use a calculate to find the final answer

What is the missing term?
Help? I don't know how to work this one out
Answer:
(n + 1) (5m + 4)
Step-by-step explanation:
⇒ (n + 1) (5m + 4)
⇒ 5mn + 4n + 5m + 4
⇒ 5mn + 5m + 4n + 4
Answer:
(n + 1)(5m + 4)
Step-by-step explanation:
Given
5mn + 5m + 4n + 4 ( factor the first/second terms and the third/fourth terms )
= 5m(n + 1) + 4(n + 1) ← factor out (n + 1) from each term
= (n + 1)(5m + 4)

Troy drew the diagram below. The inner circle has a radius of 2 units, and the outer circle has a radius of 5 units. Troy says the two circles are similar.
Which statement best explains whether Troy is correct, and why?
He is correct because the inner circle is a dilation of the outer circle.
O
He is correct because the inner circle has the same center as the outer circle.
O
He is not correct because the inner circle's radius is less than the outer circle's radius.
He is not correct because the inner circle's radius is not half of the outer circle's radius.
o
Answer:A he is correct because the inner circle is a dilation of the outer circle
Step-by-step explanation: just did the test
The statement "He is correct because the inner circle is a dilation of the outer circle" is the best explanation.
What is dilation?Dilation is the process of modifying the size of an item or form by reducing or expanding its dimensions according to specific scaling variables.
The radius of the inner circle is 2 units, while the radius of the outer circle is 5 units.
Since dilations provide similar figures because multiplying by the scale factor yields proportionate sides while keeping the angle measure and form constant.
Troy is accurate if he claims the two circles are similar.
Hence, the statement (A) "He is correct because the inner circle is a dilation of the outer circle" is the best explanation.

Find the Perimeter & Area for the following circle.
use 3.14 for Pi
Round to the tenths place
Answer:
A = 28.3 cubic inches; P = 20.1 inches
Step-by-step explanation:
Looks like 3/4 of a full circle
The area of a circle is calculated with the formula: [tex]\pi r^{2}[/tex]
Since the problem wants pi = 3.14, we use 3.14 instead of pi in the equation.
The radius is given as 3 inches
Area = [tex]3.14*3^{2} = 3.14*9 = 28.26[/tex] cubic inches = 28.3 cubic inches
------------------------
Perimeter is calculated with [tex]2\pi r[/tex].
But this is 3/4 of a circle with an additional two 3-inch sides
Perimeter = [tex]\frac{3}{4}*2\pi r[/tex] + 2(3) = 14.1 + 6 = 20.1 inches

P varies inversely with x. If P = 7 when x = 8, find the value of P when x = 7. A. 0.125 B. 1 C. 7 D. 8
Step-by-step explanation:
P = 8
Step-by-step explanation:
Given that P varies inversely with x then the equation relating them is
P = \frac{k}{x} ← k is the constant of variation
To find k use the condition P = 7 when x = 8 , then
7 = \frac{k}{8} ( multiply both sides by 8 )
56 = k
P = \frac{56}{x} ← equation of variation
When x = 7 , then
P = \frac{56}{7} = 8
