Answer:

8.84×10 To the power of -1

Step-by-step explanation:

stated number and decimal number is 8.84

goal: find the standard form of that number.

Defenition: (Plagarism Copyrights) The rules when writing a number in standard form is that first you write down a number between 1 and 10, then you write × 10(to the power of a number).

So 0.884 is 8.84/10

next put the numerator of 10 to 1 - 1/10

mulitiply 8.84 by 1/10-

this, the answer is multiply 8.84 by 10 to the power of -1

which is basically 8.84×10 To the power of -1

What is the value of the y coordinate of any point on the x axis?
Leona [35]

The value of the y coordinate of any point on the x axis is always 0.

<u><em>Explanation</em></u>

Suppose, the co ordinate of any point is (a,b) .

It means, the distance of the point from x-axis is 'b' and distance from y-axis is 'a'.

Now if the point lies on the x-axis, that means the distance of the point from x-axis will be 0. Thus, the value of 'b' will be 0.

So, the value of the y coordinate of any point on the x axis is always 0.

natta225 [31]
Hello!

Here's how much each person stacked:

Ronnie -- 0.25 of the 40 pizzas.

Mack -- 9/40

Kim -- 35% of the 40 pizzas.

Ada -- rest of the pizzas.

Now, the questions asks for who stacked the most pizzas.

First, find our how many pizzas they stacked out of 40.

40 × 0.25 = 10

40 × 35% = 14

10 + 9 + 14 = 33

40 - 33 = 7

This means that Ronnie stacked 10 pizzas, Mack stacked 9 pizzas, Kim stacked 14 pizzas, and Ada stacked 7 pizzas.

ANSWER:

Kim stacked the most pizzas since she stacked 14 of them.

After getting 5 new rocks, George gave half of his rock collection to Susan. If George gave Susan 36 rocks, which equation could
White raven [17]

Answer:

1/2 (x+5) = 36  should be the equation that is used to determine how many rocks George started with.

Step-by-step explanation:

Let 'x' be the number of rocks George had.

As George gave, after getting 5 new rocks, half of his rock collection to Susan which is = 36 rocks

It means after getting 5 new rocks George's total rocks = 72

Given that he gave half collection to Susan = 36

Thus, before inducting 5 new rocks Georg's total rocks were = 67

Thus,

1/2 (x+5) = 36 should be the correct equation.

solving

1/2 (x+5) = 36

Multiplying both sides by 2

1/2 (x+5) × 2 = 36 × 2

x+5 = 72

x = 72 - 5

x = 67

Thus, before getting 5 new rocks, the number of rocks George had = 67

Therefore,

1/2 (x+5) = 36  should be the equation that is used to determine how many rocks George started with.
