Answer:

Dave paid $4.20 more than Mel

Step-by-step explanation:

Lets start with Dave:

Turn the % into a decimal - so 7.5 % would be 0.075

Then multiply it to the amount in cost to get the tax - 24 x 0.075 = 1. 80

Now add the tax to the total - 24 + 1.8 = $25. 80  

Mel

Turn the % into a decimal - so 8 % would be 0.08

Then multiply it to the amount in cost to get the tax - 20 x 0.08 = 1. 60

Now add the tax to the total - 20 + 1.6 = $21.60  

To find the difference subtract Dave's with Mel's

$25. 80 - $21.60 = $4.20

Answer:

1) a2 = h2 + x2

✔ Pythagorean theorem

2) h2 = a2 - x2

✔ Rearrange the previous statement

3) c2 = h2 + (b-x)2

✔ Pythagorean theorem

4) c2 = h2 + b2 -2bx + x2

✔ Expand (b – x)2

Step-by-step explanation:

The Pythagorean Theorem could be represented mathematically as follows, Here, c represents the length of the hypotenuse (the longest side), or b or a are the lengths of the other 2 sides. From the equation, you can easily find the value of the 1 side if you have the values of the other 2

1) a2 = h2 + x2

Pythagorean theorem

2) h2 = a2 - x2

Rearrange the previous statement

3) c2 = h2 + (b-x)2

Pythagorean theorem

4) c2 = h2 + b2 -2bx + x2

Expand (b – x)2

Answer: The cost of 5.5 pounds strawberries =$ 7.98

Step-by-step explanation:

Given: A local grocery story has strawberries on sale for $1.45 per pound.

i.e. Cost for 1 pound strawberries = $1.45

Now, Cost of 5.5 pounds strawberries =  5.5 x (Cost for 1 pound strawberries)

= $ (5.5 x  1.45)

= $ 7.975 ≈ $ 7.98   [ Round to the nearest penny]

Hence, the cost of 5.5 pounds strawberries =$ 7.98

Part A:

lines y=-2x+9 and 4x+2y=4 can be used to create a system of equation that has no solution because none of the lines intercept on a graph.

Part B:

lines y=2x+2 and 6x-3y=6 can be used to create a system of equation that has infinitely many solutions because again none of the lines intercept on a graph

Part C:

The lines y=1/2x+1 and 4x+2y=4 can be used to create a system of equations with one solution because on a graph both lines intersect at one point.

Step-by-step explanation:

pretty sure the other guy got it right but to divided you have to do..... for example:

5/8 divided by 1 1/3

1 1/3 can be turned into 3/4.....                5/8 times 4/3

5 times 3 and 8 times 4 which equals 15/32

A circle is a shape.

Step-by-step explanation:

In geometry circles are known for you to solve the radius wit the formula      A= π r^2

A circle is a shape consisting of all points in a plane that are a given distance from a given point, the centre; equivalently it is the curve traced out by a point that moves in a plane so that its distance from a given point is constant.

Answer:

423 mph

Step-by-step explanation:

To find the answer, you have to divide 1,269 by 3 since we want to find how many miles the plane travels in one hour. Doing this, we end up with 423 which is the answer.

Step-by-step explanation:

A nonstop flight from Albuquerque, NM to Atlanta, GA takes 3 hours. If the plane flies a total of 1,269 miles, what is the plane’s unit rate in miles per hour?

1,269 % 3 = 423

Answer:

[tex]a_{64} = -313[/tex]

Step-by-step explanation:[tex]a_{64} = 2 -135[/tex]

This is the Arithmetic Sequence Formula->  [tex]a_{n} = a_{1} + (n+1) d[/tex]

1) The d represents your difference of the equation. You can find it by finding a pattern between the three numbers given, which is -5

2) Now that we've found our difference, we can plug it into this lovely sequence we have [tex]a_{64} = a_{1} + (64-1) -5[/tex] (by the way, your n represents your term that you plug into the equation)

3) [tex]a_{64} = 2 + (64-1) -5[/tex]  This also means that [tex]a_{1}[/tex] is our first term, which is 2

4) Simplify [tex]a_{64} = 2 + (63) -5[/tex] --> [tex]a_{64} = 2 +-315[/tex]

5) [tex]a_{64} = -313[/tex]

The formula is confusing at first, but it becomes easier once your learn the patterns!

Answer:

I believe that B is the correct answer!

Step-by-step explanation:

The (x+5) can cancel

Then in the numerator (x^2-25) can be factored into (x-5)(x+5) through difference of squares.

Then in the denominator the (x-5)^2 can be stretched out to (x-5)(x-5)

Lastly the (x-5) on the top and bottom will cancel resulting in result B

I hope this helped!

Answer:

B(lol the one you chose randomly was right)

5, sorry I dunno the second number...

Step-by-step explanation:

(x+5)(x+5)(x-5)/ (x+5)^2(x-5)^2

(x+5)^2 gets canceled out

Answer:

m∠b = 92 ; m∠c = 92

Step-by-step explanation:

∠b and ∠c both form supplementary angles with the 88° angle. I'll just choose b in this instance.

b + 88 = 180

b = 92

Now we know that ∠b is 92°.

Moreover, ∠c and ∠b are known as vertical angles meaning they are equivalent to each other. Therefore, ∠c is also 92°

Answer:

Answer:

[tex]A=0.0192[/tex]

Step-by-step explanation:

Diameter labeled twelve centimetres D =12cm => 0.12

height labeled thirty-two centimetres H= 32cm => 0.32

Generally the vertical cross section of this cone is a triangle

Mathematically solving

Area of vertical cross section through the center of the base of the cone is given by [tex]A=1/2 D*height[/tex]

[tex]A=R*H[/tex]

Therefore

[tex]A=\frac{0.12}{2} *0.32[/tex]

[tex]A=0.06 *0.32[/tex]

[tex]A=0.0192[/tex]
