So we start with 15 pizza's, after the party 1.5 of the pizza is left which is 3 pizza's, dog ate 25% of the 3 remaining pizza's and we know that each pizza had 12 slices so 36 slices were remaining when the dog found the pizza and 25% of 36 is 9 so we take 36-9=27 then Jill eats 5 slices, so now we have 22 slices remaining so she threw away 22 slices.

It costs $1 for 4 pounds of bananas at the local grocery store. Create a table, and equation to represent this proportional relationship.

Answers

It will be .25 cents per pound of bananas. So some marks on the graph would be (.25,1),(.5,2),(.75,3),(1,4). And the equation is y=0.25x

Answer: $0.25

Explanation: If you have $1 and you spend all your money and buy bananas each banana will cost 25p. This is because 100 divided by 4 is 25.

So to get the hypotenuse it’s the square root of a.sq+b.sq. So if a triangle had an a side of 1 inch and a b side of 1 inch than the answer would be around 1.414. If you want to get a or b just reverse the equation.

Answer:

yes you are right

Step-by-step explanation:

1) Scale 36/27 = 1.33333333 = 1 1/3 Then 20/ 1.33333333 = 15 so yes you are on right track as the shapes are congruently placed side by side for type question and note you have remembered to use the lengths with lengths and widths with widths- just remember to do fold the shapes in your head to determine this or draw dotted line to emphasise the congruency as it exposes each mid point and emphases length fro width or with triangles hypotenuse from next order of longer side within the triangle to triangle emitting smaller side from diagram on each 2) Scale = 1.75 For the second one 42/ 24 = 7/4 = 1.75 and 28/1.75 = 16 is also correct

Step-by-step explanation: Since we want to know Monday-Wednesday, we look at the information given. It says 12 bags on Monday, 3 on Tuesday, and none on Wednesday. Then we simply add these to get 15 bags for the three days, and we multiply 15 by 2.5 since that is the amount he gets per bag. 15x2.5=37.5

Recall that the perimeter of a square is equal to 4 times the length of one of its sides and the area of a square is equal to the square of one of its side.

1. Write a function. For the perimeter of the square. Is the perimeter of a square a linear I’d nonlinear function of the length of one of its sides? Explain

Answers

Answer: The equation of the line = y = 12x as s =4 because y = (length of a square)x when x is 1 and when x is 0 We then use and prove the formula y2-y1 / x2 - x 1 and one we have the slope we can show the unit for x (or add it to the equation for proof below) = s4 = 12x * 4 = isolate s = s = (12x *4)/4 = (12x *4) / 4 = to find length s therefore p = length s * 4 and s = 12x * 4 / 4 in the example below

4s = p (perimeter) The perimeter an be a linear but it has boundaries of end point = 4s so in order to find the equation of the line if s = y and s =1 given y = 1 where a length of side is possible in unit form - Which means if a square truly is equal sides then each length in units would double equally and then triple equally and quadruple equally - If the square was 120mm each length then the actual 1/12 creates a low positive linear always unless the unit is 0-9 anymore it would show a lesser steep positive linear as higher numbers for when y = 1 Therefore if 120mm = 12cm x/y = 12/1 matching coordinates (12 1) rise over er run point 1 and point 4(end point) therefore would be * 12 linear =x/y or would be * (unit length) linear =x/y in the 12 linear we would have coordinates (48 4) end point and formula 48-12 / 4-1 = 36/3 = 12 which proves the slope is always the function measure of all sides = y = 12x when x is 1 and when x is 0 given the example for when a length is 12cm

Step-by-step explanation:

4s = 12x * 4 could be the function based if using a length of 12cm or equation of the line = y = 12x and s =4

Answer:

z = 13 degrees

Step-by-step explanation:

1.) Those two angles add up to 90 degrees, so we can say that 5z - 6 + 2z + 5 = 90

2.) Simplify both sides to get 7z - 1 = 90.

3.) Isolate Variable by adding 1 on both sides to get 7z = 91.

4.) Divide by 7 on both sides to find that z = 13 degrees.

Answer:

z = 13

Step-by-step explanation:

5z - 6 + 2z + 5 = 90

7z - 1 = 90

7z = 91

z = 13

Dave owns 15 shares of ABC mining stock. On Monday, the value of each share rose $2, but on Tuesday the value fell $5. What is the change in the value of Dave’s shares?

Answers

Answer:

Let's take each share by itself first.

First, the value of each share rose by 2. So we have +2. Then it fell by 5. So we have 2 - 5 = -3. Each share has a net value of negative 3.

Dave owns 15 shares. So 15 * (-3) = -45.

-$45

In short, the answer is $45

Let x = the current value of the stocks

So if each stock increases by 2 dollars - the total value increases by 15 lots of $2

x + (15 x 2) = the new value (we will call this n)

Each stock then decreases in value by $5

So…

n - (5 x 15) = the final value of the stocks (we will call it f)

$2 - $5 = -3$

And -3 x 15 = -45

So Dave has lost $45 in shares
