From the picture you can see that TY bisects angle T.

Use the bisector property:

\dfrac{TK}{KY} =\dfrac{TV}{VY}.

If YK=68 mm and VK=x mm, then VY=x-68 mm.

Then \dfrac{129.2}{68} =\dfrac{57}{x-68}.

Express x-68:

x-68=\dfrac{57\cdot 68}{129.2}=30 mm.

Therefore, x=30+68=98 mm.

Answer: x=98 mm.

What is the area of the figure?
xenn [34]

Answer:   17.5 square yards

================================================

Work Shown:

base = 5 yards

height = 7 yards

The base and height are always perpendicular to one another

area of triangle = 0.5*(base)*(height)

area of triangle = 0.5*(5)*(7)

area of triangle = 17.5 square yards

The other values aren't used. They're likely thrown in as a distraction.

A special deck of cards has ten cards. Four are green (G), four are blue (B), and two are red (R). When a card is picked, the co
a_sh-v [17]

Answer:

{GT, GH, BT, BH, RT, RH};

1 /5;

Mutually exclusive ;

Not mutually exclusive.

Step-by-step explanation:

Given :

Green cards, G = 4

Blue cards, B = 4

Red cards, R = 2

For a coin toss :

{H, T}

A card is picked, then a coin is tossed :

Sample space :

{GT, GH, BT, BH, RT, RH}

2.) probability of picking a green card, then probability of landing a head on a coin toss

P(A) = number of required outcome / Total possible outcomes

P(A) = P(green card) * P(Head)

P(A) = (4 / 10) * (1/2)

P(A) = 4 /20

P(A) = 1/5

C.)

Both A and B are mutually exclusive, since both event A and event B cannot occur together, since both red and green cannot be picked during a single pick, this either a red is picked or green is picked, then they are A and B are mutually exclusive.

D.) Event A and C are not mutually exclusive, picking a green card, event A and picking a red or blue card, event B. Both event can happen simultaneously, hence, event A and B are not mutually exclusive.

If you know that the exact volume of a cylinder is 500 π cm3, how can you find the approximate volume, without knowing the heigh
grandymaker [24]

Answer:

The approximate volume is 1,570\ cm^{3}

Step-by-step explanation:

we know that

The exact volume of the cylinder is  

V=500\pi \ cm^{3}

so

To find the approximate volume of the cylinder, substitute the term \pi by the approximate value of  3.14 and then multiply  

so

V=500(3.14)=1,570\ cm^{3}
