$\begin{gathered} m\angle2=m\angle6\text{ are corresponding angles} \\ \angle2\cong\angle6\text{ are the same because the both angles are corresponding} \end{gathered}$ $\begin{gathered} m\angle2+m\angle3=180\text{ are angles on a straight line.} \\ \text{angles on straight line =180 degree} \end{gathered}$ $\begin{gathered} m\angle3+m\angle6=180\text{ are supplementary angles} \\ \text{supplementary angles = 180 degree} \end{gathered}$ $\begin{gathered} m\angle2+m\angle3=m\angle3+m\angle6 \\ angles\text{ on a straight line(180 degree)=supplementary angles(180 degree)} \end{gathered}$

There are 3 types of sweets in a jar.

KengaRu [80]

Answer:

$\frac{2}{3}$

Step-by-step explanation:

Given:

Number of eclairs = 3

Number of humbugs = $2x + 6=2(x+3)$

Number of mints = $x$

Therefore, total number of sweets in the jar is,

$S=3+2x+6+x=3x+9=3(x+3)$

Now, probability of selecting a sweet to be humbug is given as:

$P(humbug)=\frac{\textrm{number of humbugs}}{\textrm{number of sweets}}\\P(humbug)=\frac{2(x+3)}{3(x+3)}=\frac{2}{3}$

Therefore, the probability that it is a humbug is $\frac{2}{3}$ .

How do i answer this and how do i find the modal

faltersainse [42]

So firsty up, you need to have equal denominators IN order to do this equation.

1/3 and 5/12..

3x4=12

So the rule when changing denominators, you multiply 4 intop, so it will become 4/12, and 5/12 + 4/12 = 8/12, and,

8/12 + 1/12= 9/12 and 9/12 simplified is 3/4..

So the answer is 3/4.

Hope this helped.

What is the lateral area of a right cylinder if the radius of the base is 12 mm and the altitude of the cylinder is 5 times the

schepotkina [342]

Lateral Area of a cylinder is ; 2πR.H

R=12 mm and H= 15 mm

Then LATERAL area = 2π(12)(15) =48π ≈ 150 mm²
