If DE = 4 x + 10, EF = 2 x -1, and DF = 9 x - 15, what is the length of DF?

Answer:

1) 6/10

2) 16/100

Step-by-step explanation:

1/3x18

2/5x40

of = multiply

Answer:

10

Step-by-step explanation:

[tex]\frac{1}{3}[/tex] × 18 = 18 ÷ 3 = 6

[tex]\frac{2}{5}[/tex] × 40 = (40 ÷ 5) × 2 = 8 × 2 = 16

Difference = 16 - 6 = 10

Step-by-step explanation:

diameter =20inches

radius =20/2=10 in

Surface area of sphere, A = 4πr²

π=3.14

Answer:

x is all real numbers

Step-by-step explanation:

4(x + 1) = 4x + 4

Distribute

4x+4 = 4x+4

Subtract 4x from each side

4x+4-4x = 4x+4-4x

4=4

This is always true so there are infinite solutions

x is all real numbers

Answer:

80.77777778

Step-by-step explanation:

when dividing 727 by 9, think about how many times does 9 go into 7? none.

next how many times does 9 go into 72? 8 times!

but since we have established 9 cannot go into 7 we need to know how many times does 9 go into 727, since it goes into 72 8 times already try adding a zero behind that 8. So what is 80(9)? it's 720. So the answer would be 720 with a remainder of 7. :)

Answer:

7.57

Step-by-step explanation:

the area = 44/360 × π × r²

7 π = 44/360 × π× r²

eliminate π

7 = 44/360 x r²

r² = 7× 360/44

r² = 57.27

r =√57.27 = 7.57

Answer:

B: 0.628

Step-by-step explanation:

Place value rules.

The value of each digit in a number is known as the place value. The number that has 6 tenths, 2 hundredths, and 8 thousandths can be written in the standard form as 0.628. The correct option is B.

The value of each digit in a number is known as the place value. The 5 in 350, for example, represents 5 tens, or 50, whereas the 5 in 5,006 represents 5 thousand, or 5,000. It is critical that children that while a digit can be the same, its value is determined by its position in the number.

Identification of the place value of a digit in a number:

Given 6 tenths, 2 hundredths, 8 thousandths, this can be written in the standard form as,

Standard form = 0.6 + 0.02 + 0.008 = 0.628

Hence, the number that has 6 tenths, 2 hundredths, and 8 thousandths can be written in the standard form as 0.628.
