Gary has 2 apple pies and each is divided into 8 equal parts. He serves 4/8 of the first pie. How much pie does he have left?

1/2 because he has 16 pieces gives 4/8 which is a half and therefore has a half left

So 2 whole pies with each 8 slices. He gives half of one so 1 1/2

2/1 - 4/8 = 16/8 - 4/8 = 12/8 simplified to 1 1/2

But literally it's just half missing so 2 - 1/2 = 1 1/2 also works.

Which figures are polygons? Figure A has 6 sides all made of line segments. figure b is a regular hexagon. it has 6 sides made a

Naddika [18.5K]

<span>A polygon is a closed figure made by joining line segments, where each line segment intersect exactry two other line segments.

A polygon is said to be a regular polygon if the sides are all of the same length.

Thus, the figures that are polygon are:

</span><span>Figure A which has 6 sides all made of line segments.

Figure B which is a regular hexagon, having 6 sides made all of segments.

</span><span>Figure D has 7 sides which are all segments.</span>

there are 4 quarters for every one dollar and 10 dimes for every dollar. Without graphing, would the ratio of quarters to dollar

grin007 [14]

Answer:

Step-by-step explanation:

remember lines and line equations.

y = ax + b

a line has a slope indicating its angle relative to the basic coordinate axis and grid of x and y.

the slope is "a" in the generic equation, always the factor of x.

and it stands for the ratio y/x. it means how many units is y changing (and in what direction via its sign), when x changes a certain amount of units.

e.g. 3/4 means, when x changes 4 units to the positive (right) side, then y changes 3 units to the positive (up) side.

and also, when x changes 4 units to the negative (left) side, then y changes 3 units to the negative (down) side, as -/- is again +.

or -3/4 means, when x changes 4 units to the positive (right) side, then y changes 3 units to the negative (down) side, as -/+ is -.

and also, when x changes 4 units to the negative (left) side, then y changes 3 units to the positive (up) side, as +/- is again -.

so, we have here 2 ratios : 4/1 (quarters to dollars) and 10/1 (dimes to dollars).

remember what that means : y/x.

when x changes 1 unit to the right (x increases by 1), y changes 4 units up (y increases by 4).

and when x increases by 1 unit, y increases by 10 units.

what do you think is the steeper line ?

both are steep, as y increases much faster than x. but in the 10/1 ratio y increases much faster than in the 4/1 ratio. so, 10/1 is steeper than 4/1.

therefore, the answer is no. the ratio quarters to dollars does not represent a steeper line.

by the way, ratios like 4/1 or 10/1 are simply written 4 or 10.

so, when you see a line equation like y = 3x + 2,

you know the slope is 3 or actually 3/1.

Three different divers kept track of the number of treasure boxes they've found this year. Diver Dives Treasure boxes found Scub

jok3333 [9.3K]

Answer:

Wet Suit Willy found the most treasures per dive.

Step-by-step explanation:

Given:

Diver name Number of dive Number of boxes

Sam 11 33

Wet Suit Willy 18 81

Deep Diving Dan 26 104

Find:

Who found the most treasures per dive

Computation:

Sam's per dive collection = 33 / 11 = 3 boxes

Wet Suit Willy's per dive collection = 81 / 18 = 4.5 boxes

Deep Diving Dan's per dive collection = 104 / 26 = 4 boxes

Wet Suit Willy found the most treasures per dive.

A shop has a sale that offers 20% of all prices.

Nana76 [90]

<h2>Greetings!</h2>

Answer:

40% reduction

Step-by-step explanation:

To answert this, we need to find how much of the price is each percentage. This can be found my subtracting the percent from 100:

Sale price: 100 - 20 = 80

Last day price: 100 - 25 = 75

Now we need to multiply these two values together, remembering to divide both numbers by 100 first:

80 ÷ 100 = 0.8

75 ÷ 100 = 0.75

0.8 * 0.75 = 0.6

Then multiply by 100 to find the percentage:

0.6 * 100 = 60

60% is the end price, but to find the overall reduction we need to subtract this value from 100:

100 - 60 = 40

So there was a 40% reduction on the price.

There are approximately 3.6 million deaths per year in country A. Express this quantity as deaths per minute.

morpeh [17]

About 6 or 7 deaths per minutes because if you divided 3.6 million by the amount of minutes in a year (525,600) you get 6.84931506 on and on.
