Ribbon A is 1/3 m long. It is 2/5 m shorter than Ribbon B. What's the total length of the two ribbons?

Softa [21]

Answer:

$\frac{11}{15}$

Step-by-step explanation:

A = $\frac{1}{3}$

B = $\frac{2}{5}$

A = $\frac{1x5}{3x5}=\frac{5}{15}$

B = $\frac{2x3}{5x3}=\frac{6}{15}$

$\frac{5}{15}$ + $\frac{6}{15}$ = $\frac{11}{15}$

Good Luck!

Find the volume of the cone

irina1246 [14]

Answer:

The volume of the cone is 12936 cubic mm.

Step-by-step explanation:

Given

Circumference of base = 132 mm

Height of the cone = 28 mm

Solution

Formula of circumference = $2\pi r$ = 132 mm

$\therefore\ r= \frac{132}{2 \pi } = 21 mm$

Now volume of cone = $\frac{1}{3} \times\pi \times r^{2} \times h$

on substituting the value of r and h we get ;

$\frac{1}{3}\times\frac{22}{7} \times21\times21\times28= 12936\ mm$

thus volume of cone is 12936 cubic mm.

What is the value of x if e^3x+6 = 8?

topjm [15]

We can write any number n in the form $e^{\ln(n)}$ , since $e^x$ and $\ln(x)$ are inverse functions, so that

$e^{3x+6} = 8 \iff e^{3x+6} = e^{\ln(8)}$

The bases are the same on both sides, so the exponents must be equal.

$3x + 6 = \ln(8)$

Solve for x :

$3x = \ln(8) - 6$

$x = \boxed{\dfrac{\ln(8) - 6}3}$
