UNO [17]

Answer:

x=(10,0)

y=(0,4)

Then put 10 into your new equation in the x spot and thats how you get y

Hope this helps:)

Martha has a deck of cards. She has lost some of the cards, and now the deck only contains nine spades, eleven diamonds, eight c

Zielflug [23.3K]

Answer:

D. Randomly draw and replace a card 100 times. Then, observe how close to 20 times a club is drawn.

Step-by-step explanation:

We are given that,

Martha predicts that 'whenever she draws a card from the deck without looking, she will draw a club one-fifth of the time'.

Now, according to the options, we see that,

If she randomly draw and replace a card 100 times and then observe how close to 20 times a club is drawn.

Her prediction is most likely to be true.

As, 20 out of 100 times is $\frac{1}{5}$ th of the total time.

Hence, option D is correct.

On a map, each centimeter represents 50 m.

PSYCHO15rus [73]

Tameka's claim is incorrect, because the actual area of the park is 15000 square meters.

The scale measurement of the area of the park is given as:

$1cm : 50m$

Square both sides of the ratio

$(1cm)^2 : (50m)^2$

$1cm^2 : 2500m^2$

Multiply both sides of the ratio by 6

$6 \times 1cm^2 : 6 \times 2500m^2$

Evaluate both factors

$6cm^2 : 15000m^2$

The above means that the actual area of the park is 15000 square meters.

Hence, Tameka's claim is incorrect
