answer for 1a: 0.40, which is 40 cents.

what you need to do is you need to divide the amount of money of the drink which is £3.20, by the quantity of the drink which is 8, since £3.20 is the total amount of money for 8 cans.
£3.20 divided by 8 is 0.4, which logically would mean in your question it calculates to 40 cents.
another proof that the answer is 40 cents is when you multiply 0.40 by 8, it calculates to 3.2, which would mean in your question it calculates to £3.20 in total.
the answer to 1a is 40 cents.


answer for 1b: 0.35, which is 35 cents.
same thing as the first question, you need to divide the total amount of money of the drink which is £5.25, by the quantity of the drink which is 15, to calculate the actual price of the drink.
5.25 divided by 15 calculates to 0.35.
as said, the proof that the answer is right is if you multiply 0.35 by 15, it will calculate to 5.25.
the answer to 1b is 35 cents.

answer for 1c: the best value is shop A, because we have worked out that shop A sells the drink for 40 cents, and shop B sells the drink for 35 cents. therefore, shop A gets 5c more profit than shop B.

A man realizes he lost the detailed receipt from the store and only has the credit card receipt with the after-
tax total. If the after-tax total was $2,096.25, and the tax rate in the area is 7.5%, what was the pre-tax
subtotal?

Answers

Answer:

107.5% = 2096.25

1% = 19.5 ( divide both sides by 107.5)

100% = 1950 ( multiply both sides by 100)

pre tax $1950

Answer:

2x+y < 7

Step-by-step explanation:

We  are below the line which means less than ( since the line is dotted)

We need to determine the equation for the line

The y intercept is 7 and the slope is

( 0,7) and (2,3)

m = ( 3-7)/( 2-0) = -4/2 = -2

In slope intercept form ( y=mx+b)

y = -2x+7

Changing this to an inequality

y < -2x+7

Add 2x to each side

2x+y < 7

[tex](-3x^2y)^{4}[/tex]


PLEASE EXPLAIN HOW YOU GOT YOUR ANSWER

Answers

Answer:

errr polynomials ahaha

so basically we can multiply the power outside of the parantheses with the exponents on the inside:

so

[tex]-3x^{2*4} y^{1*4}[/tex]

this will give us:

-3x^8y^4

we also unfortunately, have to use the power on the coefficient -3 as well  and we cant just MULTIPLY -3 by 4, we are going to have to multiply -3 with -3 4 TIMES(anytime we see a coefficient we MUST multiply the coefficient by itself according to the number outside of the parantheses)

so:

-3*-3*-3*-3=81

final expression

[tex]81x^{8}y^{4}[/tex]

When you have an power outside of a bracket, you have to multiply all the powers inside by the one outside...

So you would get x^2 x ^4 which is x^8

And y x ^4 which would be y^4

Therefore the answer will be -3x^8y^4

Hope this helps! Any questions let me know :)

Find 5 solutions for the linear equation x+5y=21 and plot the solutions as points on a coordinate plane

Answers

Answer:

(21, 0), (16, 1), (11, 2), (6, 3), (1, 4) are solutions of  [tex]x + 5\cdot y = 21[/tex]. Please see the image attached below to know the plot on the coordinate plane.

Step-by-step explanation:

Let [tex]x + 5\cdot y = 21[/tex], we can determine five distinct points by transforming this function into its explicit form. That is:

[tex]x = 21 - 5\cdot y[/tex]

Then, we evaluate the function at five distinct values of [tex]y[/tex]:

y = 0

[tex]x = 21-5\cdot (0)[/tex]

[tex]x = 21[/tex]

y = 1

[tex]x = 21-5\cdot (1)[/tex]

[tex]x = 16[/tex]

y = 2

[tex]x = 21 - 5\cdot (2)[/tex]

[tex]x = 11[/tex]

y = 3

[tex]x = 21-5\cdot (3)[/tex]

[tex]x = 6[/tex]

y = 4

[tex]x = 21-5\cdot (4)[/tex]

[tex]x = 1[/tex]

(21, 0), (16, 1), (11, 2), (6, 3), (1, 4) are solutions of  [tex]x + 5\cdot y = 21[/tex].

Which congruence theorem best expresses the relationship showing that the triangles below are congruent? And why?
These are the options:

A= SSS
B= SSA
C- SAS
D- ASA

Answers

Answer:

I think is asa but if not sorry

The ASA congruence theorem best expresses the relationship showing that the triangles given are congruent to each other.

What is Congruence of Triangles?

Two or more triangles are said to be congruent if and only if sides and angles of one triangle is equal to the corresponding sides and angles of another triangle.

Given are two triangles.

Two angles of each triangle are marked as 64° and 72°.

So we have two angles of one triangle is equal to corresponding two angles of another triangle.

We also have from the figure two sides are equal to each other and this side is the included side of the equal angles.

So two angles and an included side of one triangle is equal to corresponding two angles and included side of another triangle which is theorem of ASA congruence.

Hence the given two triangles are congruent by ASA congruence rule.

Priya's cat weights 5 1/2 pounds and her dog weighs 8 1/4 pounds. The dog is ______ pounds heavier than the cat.

Answers

Answer:

[tex]2\frac{3}{4}[/tex]

Step-by-step explanation:

We have to subtract the weight of the cat from the weight of the dog.

[tex]8\frac{1}{4} -5\frac{1}{2}[/tex]

The first issue here is that there is not a common denominator. I'm going to multiply that 1/2 by 2 to make it 2/4. The 5 does NOT change.

[tex]8\frac{1}{4} -5\frac{2}{4}[/tex]

Subtract the whole numbers first.

[tex]8\frac{1}{4} -5\frac{2}{4} = 3\frac{1}{4} -\frac{2}{4}[/tex]

Then, we'll convert the first term to an improper fraction. We can do that by multiplying the whole number by the denominator and adding that number to the numerator.

[tex]3\frac{1}{4} -\frac{2}{4} ==> \frac{13}{4} - \frac{2}{4}[/tex]

Solve.

[tex]\frac{13}{4} -\frac{2}{4} = \frac{11}{4}[/tex]

Then, convert to a mixed number by dividing 11 by 4 and leaving the remainder in the numerator and putting the quotient in front as the whole number.

[tex]\frac{11}{4} ==> 2\frac{3}{4}[/tex]

So, the answer is [tex]2\frac{3}{4}[/tex]
