Answer:

a) 3/40

Step-by-step explanation:

Answer:

3/40 (3 over 40 )

Step-by-step explanation:

3 / 5 ÷ 8

3 / 5 × 1 / 8 ( when dividing fractions you need to invert and multiply invert the seccond fraction )

3 * 1 = 3 and 5 * 8 is 40

So the answer is 3/40

Answer:

3 apples for 1.29

Step-by-step explanation:

If you divide 1.29 by 3, you will get 0.43 which means each apple then costs 0.43 each. This is less than 0.45 so it is the better value.

Answer:

$1.29 for 3

Step-by-step explanation:

The reason is that $0.45 per apple means for every apple, you have to pay $0.45. That eventually is going to start to add up. $1.29 for 3 means that you are paying $0.43 for 3, which means that you are saving money.

Answer:

C

Step-by-step explanation:

Use Δ ABC to find AB then Δ ABD to find DB

Δ ABC  is isosceles since ∠ CAB = ∠ CBA = 45° , then CB = CA = 2

Using Pythagoras' identity in Δ ABC , then

AB² = 2² + 2² = 4 + 4 = 8 ( take square root of both sides )

AB = [tex]\sqrt{8}[/tex] = 2[tex]\sqrt{2}[/tex]

----------------------------------------------------------------

Using the sine ratio in Δ ABD with the exact value

sin60° = [tex]\frac{\sqrt{3} }{2}[/tex] , then

sin60° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AB}{DB}[/tex] = [tex]\frac{2\sqrt{2} }{DB}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )

[tex]\sqrt{3}[/tex] × DB = 4[tex]\sqrt{2}[/tex] ( divide both sides by [tex]\sqrt{3}[/tex] )

DB = [tex]\frac{4\sqrt{2} }{\sqrt{3} }[/tex] ( multiply numerator/ denominator by [tex]\sqrt{3}[/tex] to rationalise denominator )

     = [tex]\frac{4\sqrt{2} }{\sqrt{3} }[/tex] × [tex]\frac{\sqrt{3} }{\sqrt{3} }[/tex]

     = [tex]\frac{4\sqrt{6} }{3}[/tex] → C

Answer:

84x+50

Step-by-step explanation:

First, you would find the area of the entire square. The area of a square is LW, so you would multiply (7x+6)(7x+6). For this, I would use the FOIL method, so you would multiply the first terms which would be (7x)(7x)=14x^2. Then the outside terms, so (7x)(6)=42x. Then the inside, so (7x)(6)=42x. Finally, the last terms, 6(6)=36.

Then you would combine them, so the area of the whole square is [tex]14x^{2} +42x+42x+36[/tex] which would equal [tex]14x^{2} +84x+36[/tex].

Then, the area of the smaller square is (x)(x) which would equal [tex]x^{2}[/tex].

Then you would subtract the smaller square from the bigger one, so the final answer would be [tex]14+84x+36[/tex] which you could simplify to [tex]84x+50[/tex]

Answer: 180.36

Step-by-step explanation:

I wasn’t sure if the questions was saying each ball was 29.99 or the total of the soccer balls was 29.99 without tax.

How I got the answer:

29.99 was the cost per soccer ball and he needed 6 of them and the tax was 7% which equal up to 0.07.

29.99 times 6 = 179.94

0.07 times 6 = 0.42 (the more you buy the more the tax raises)

179 + 0.42 = 180.36

The total is 180.38

Answer:

1. y= 10      2.y= -10      3.y= 6      4.y= -2

Step-by-step explanation:

You basically just replace x with the number.

So, for y = 4 + 2x, then replace x with 3 and go y = 4 + 2(3)

which translates to y = 4 + 6 which equals 10

Answer:

10, - 10, 6, - 2

Step-by-step explanation:

Substitute each given value of x into the expression and evaluate.

x = 3 → y = 4 + 2(3) = 4 + 6 = 10

x = - 7 → y = 4 + 2(- 7) = 4 - 14 = - 10

x = 1 → y = 4 + 2(1) = 4 + 2 = 6

x = - 3 → y = 4 + 2(- 3) = 4 - 6 = - 2

Answer:

L= -12

W=  -36

I believe the answer is: The tax deferred nature.

Investment is considered to has tax deferred nature if the tax payment for the investment can be made years later after its due. This favoured as a retirement plan because it make the investors have more money to spend during the productive years prior to retirement.

The y intercept is -2, because that is the point where the line hits the vertical y intercept. The slope is - 1/4

Step-by-step explanation:

Answer:

y-intercept = -2

Given:

A point is reflected across the y-axis. The reflected point is (3.5,6).

Jimmy says the original point is (3.5,-6).

To find:

Whether Jimmy's statement true or false

Solution:

If a point is reflected across the y-axis, then y-coordinate remains same but change the sign of x-coordinate.

[tex](x,y)\to (-x,y)[/tex]

If the reflected point is (3.5,6), then the original point must be (-3.5,6), which is not equal to (3.5,-6).

Therefore, Jimmy's statement is false.

============================================================

Explanation:

Let's label (0,7) as point C.

Plot points A and C on the same coordinate system.

Note that to go from A to C, we must do two things (in either order)

These two items will be replicated in either order to go from point C to point B.

The translation rule we follow is [tex](x,y) \to (x+6, y+1)[/tex] which is a mathematical way of saying "go right 6 and up 1". If we plug in x = -6 from point A we get to x = 0 which is the x coordinate of point C. Repeating this leads to x = 6, which is the x coordinate of point B.

Through similar arguments, we go from y = 6, to y = 7, to y = 8, when we hop from points A, to C, to B in that exact order.

Put everything together and we see that B is located at (6,8)

The diagram below provides a visual summary.

----------------------------------------------------

Extra info:

If we draw a line from point A to B, then point C will be on this line. Furthermore, AC = CB which can be proven using congruent triangles. Reflections preserve distance, meaning the distance from A to the mirror point C, is the same as from B to C as well. In short, we can say C is the midpoint of segment AB.

Answer:

top graph

Step-by-step explanation:

The graph of a proportional relationship is a straight line passing through the origin.

The only straight line graph passing through the origin is the top one

The graph on option A displays a proportional relationship.

Option A is the correct answer.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

The equation of the line on the graph is given as:

y = mx + c ____(1)

The graph on option A.

If the equation of a line is y = mx and the slope is a unit rate the graph shows proportional relationships.

We will select two points on the graph.

i.e

(2, 2) = (a, b) and (3.3) = (c, d)

Slope:

m = (d - b) / (c - a) = 3 - 2 / 3 - 2 = 1 / 1 = 1

Let (2, 2) = (x, y) and putting in (1) we get,

2 = 1 x 2 + c

2 = 2 + c

c = 2 - 2 = 0

c = 0

The slope of the line is 1

The equation of the line is y = x

Thus,

The graph displays a proportional relationship.

Option A is the correct answer.
