Seven less than four times a number is nine. FIND the number

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

Step-by-step explanation:

diameter =20inches

radius =20/2=10 in

Surface area of sphere, A = 4πr²

π=3.14

area = 4×3.14×(10)²

area=1,256 in²

Answer: the equation is y = -5x/6 - 2

Step-by-step explanation:

x1 = -6

y1 = 3

x2 = 6

y2 = -7

now

m(slope) = rise/run = (y2-y1)/(x2-x1)

   = (-7-3)/(6-(-6))

  =  -10/12

   = -5/6

now

y = mx+ b

-7 = m*6 + b

or, -7 = -5/6*6 + b

or, -7 = -5 + b

so, b = -2

now

y = mx +b

y = -5/6*x + (-2)

y = -5x/6 - 2

Answer:

y = -5/6 × x - 2 = -5x/6 - 2

Step-by-step explanation:

we have two marked points with seemingly integer coordinates for x and y.

the equation of a line is

y = a×x + b

now, we only need to put the x and y values pairs into this equation and calculate a and b.

P1 = (-6, 3)

P2 = (6, -7)

based on what I can see on the picture.

starting with P1

3 = a×-6 +b

b = 3 + a×6

then with P2

-7 = a×6 + b = a×6 + 3 + a×6 = a×12 + 3

-10 = a×12

a = -10/12 = -5/6

=>

b = 3 + a×6 = 3 + -5/6 × 6 = 3 - 5 = -2

so, the line equation is

y = -5/6 × x - 2 = -5x/6 - 2

Answer:

33131

Step-by-step explanation: 34343-1212= 33131

Hi! I'm happy to help!

To find the difference, means to use subtraction. So, to solve this, we need to subtract.

34343-1212=33131

The difference between 34343 and 1212 is 33131.

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.

the answer might be 20

Step-by-step explanation:

first you add 3.1 to 3.1 to get 6.2

then you multiply 6.2 by 2.27

then you add the answer you get from that to 3.1+3.1 to get the final length ‍to be 20.274 and that would be 20 in the nearest tenth
