What number is in the ten-thousandths spot of pi?
Nesterboy [21]

Answer:To figure out the value you have to look at all of the numbers from right to left.  You start with the ones place and get prgressively bigger going up by a multiple of 10 each time.  So you have the ones, tens, hundreds, thousands, ten thousands, etc.  In the number in your example, you have 3 ones, 4 tens (or 40), 1 hundred or (100), 0 thousands, and 5 ten thousands (50, 000).  You can write the number in expanded form to help you figure out the value.  50,000 + 100 + 40 +3.

(-6x3-4x2-8)+(x3-x2-9x+4) add together and simply
Aleksandr [31]

Answer:

-5x³ -5x² -9x - 4

Step-by-step explanation:

(-6x³-4x²-8)+(x³-x²-9x+4)

Add the like terms.

-6x³ and x³ are like terms. -6x³ + x³ = -5x³

-4x² and -x² are like terms. -4x² - x² = -5x²

-8 and 4 are like terms. -8 + 4 = -4

-6x³-4x²-8 +x³-x²-9x+4 = -5x³ -5x² -9x - 4

In the diagram below of triangle OPQ, R is the midpoint of OQ and S is
lyudmila [28]

Answer:

Measurement of OP = 12

Step-by-step explanation:

Given:

R is mid point of OQ

S is mid point of PQ

RS = 18 – 4x

OP = -9 + 7x

Find:

Measurement of OP

Computation:

R is mid point of OQ and S is mid point of PQ;

By using mid point theorem

[1/2][OP] = RS

So,

[1/2][-9 + 7x] = [18 - 4x]

[-9 + 7x] = 2[18 - 4x]

-9 + 7x = 36 - 8x

7x + 8x = 36 + 9

15x = 45

x = 45 / 15

x = 3

So,

OP = -9 + 7x

OP = -9 + 7(3)

Measurement of OP = 12
