Answer: No

Step-by-step explanation: Simplify 2/8 ÷ 2 which will equal 1/4. Like money, 4 quarters equals a dollar so 1/4 would equal 25% 1/2 is one half and we know that half of something is 50%. So it is not greater than 1/2 :D

Find any 3 (x,y) pairs that are solutions for the equation 2x-5y=10 . Show your work

Alla [95]

Answer:

(0,-2), (5,0) and (10,2).

Step-by-step explanation:

Given equation is $2x-5y=10$ .

Now we need to find 3 pairs of solutions in (x,y) form for the given equation.

As $2x-5y=10$ is a linear equation so we are free to pick any number for x like x=0, 5, 10

Plug x=0 into $2x-5y=10$ , we get:

$2(0)-5y=10$

$0-5y=10$

$-5y=10$

$y=\frac{10}{-5}$

$y=-2$

Hence first solution is (0,-2)

We can repeat same process with x=5 and 10 to get the other solutions.

Hence final answer is (0,-2), (5,0) and (10,2).

Find the cos A and tan B to four decimal places. URGENT

Nikolay [14]

cos A is 0.8511 and tan B is 1.6

Step-by-step explanation:

Find the 3rd length or the hypotenuse.

Pythagoras theorem

$hypotenuse^{2}$ = $adjacent^{2}$ + $opposite^{2}$

$hypotenuse^{2}$ = $8^{2}$ + $5^{2}$

$hypotenuse^{2}$ = 64 + 25

hypotenuse = $\sqrt{89}$

hypotenuse = 9.4

a) Cos A

Data:

Adjacent = 8

Hypotenuse = 9.4

Formula:

Cos (Angle) = $\frac{adjacent}{hypotenuse}$

Cos A = $\frac{8}{9.4}$

Cos A = 0.8511

A = $cos^{-1}$ (0.8511)

A = 31.7°

b) Tan B

Data:

Opposite = 8

Adjacent = 5

Formula:

Tan (Angle) = $\frac{opposite}{adjacent}$

Tan B = $\frac{8}{5}$

Tan B = 1.6

B = $cos^{-1}$ (1.6)

B = 58°

Therefore, cos A is 0.8511 and tan B is 1.6.

Hope is the coach of the Wilson High School girls' soccer team. There are 3 minutes left in the game they are currently playing,

NISA [10]

To answer this question, we need to find the winning probability in either case.

Probability = no. of outcomes / total no. of possible outcomes

When Hope pulled her defender :

Total no. of games = 9

No. of games won = 3

Winning probability = 3/9 =1/3

When Hope left her defender :

Total no. of games = 10

No. of games won = 6

Winning probability = 6/10 = 3/5

We know that , 1/3 < 3/5.

So, Hope should not pull her defender, as the winning probability is better when Hope left her defender.

Answer : A. Hope should not pull her defender.
