X+x+x-15+x-15=98 simplifies to 4x-30=98 move the 30 over 4x=98+30 simplify and you have 4x=128 divide both sides by 4 and you're left with x=32 which is your length, your width is 32-15 which is 17.

Half of perimeter (or L+ W) is:
98/2= 49 (cm)

L- W= 15
L+ W= 49

L= (49+ 15)/2= 32
W= (49-15)/2= 17

The length is 32 cm and the width is 17 cm~

Answer:

$52.3m^2$

Step-by-step explanation:

Use these formulas

$A=\pi rl+\pi r^2\\l=\sqrt{r^2+h^2}$

Now solve

$A=\pi r(r+\sqrt{h^2+r^2} )\\=\pi *2*(2\sqrt{6^2+2^2} )\\=52.3m^2$

makkiz [27]

9514 1404 393

Answer:

420

Step-by-step explanation:

The prime factors of each denominator are ...

12 = 2²×3

14 = 2×7

5 = 5

10 = 2×5

The unique factors are 2²×3×5×7 = 420.

The least common denominator of these fractions is 420.

kotegsom [21]

Answer:

y = 3x + 62

Step-by-step explanation:

Trend line equation in the form :

y = mx + b

m = slope

b = intercept

Using the points :

(0, 62) ; (6, 80)

Slope, m = Rise / Run = (y2-y1) / (x2 - x1)

y2 = 80 ; y1= 62 ; x2 = 6 ; x1 = 0

m = (80 - 62) / (6 - 0)

m = 18 / 6

m = 3

Intercept, b = value of y when x = 0

(0, 62) ; hence, b = 62

y = 3x + b

y = 3x + 62

Ksenya-84 [330]

Answer:

3:the value of the 4 in 0.04 is the value of the 4 in 0.4 divided by 10.

Step-by-step explanation:

This is because in decimal places, we have what is called place value. In a decimal number after the decimal point, each number place is divided by an increasing power of 10. So, for example, if we have a decimal number 0.82, the place value of the 8 is 8/10 while that of the 2 is 2/10² = 2/100.

So, in the given numbers, 0.04 has a place value of 4/100 and 0.4 has a place value of 4/10. So, we can see that 4/100 = 4/10 ÷ 10 = 4/10 × 1/10.

So, the value of the 4 in 0.04 is the value of the 4 in 0.4 divided by 10.
