Answer:

Answer is 49

Step-by-step explanation:

Add all the ratios up you get 21 so then you divide 147 by 21 thus giving you 1 ratio = 7 respectively, and we know the ratio of the red is 7 because it's stated red, blue, and green -> 7,6,8. So then 7 * 7 = 49. And to confirm you can do (7*7)+(6*7)+(8*7) which should equal 147

Yes, the new coordinates would be:

R': (9,9)
P': (3,3)
Q': (9,3)

You would multiply all of the current coordinates by three (its scale factor of enlargement) to obtain these answers. Hope this helps!

Order these from least to greatest 3 39/40 , 3 19/20 , 3 1/2
Lera25 [3.4K]

Hey!

First change all the fractions so that they have a common denominator: 40

3 \frac{39}{40} = 3 \frac{39}{40}

3 \frac{19 \times 2}{20 \times 2} = 3 \frac{38}{40}

3 \frac{1 \times 20}{2 \times 20} = 3 \frac{20}{40}

Now order them:

3 \frac{39}{40} , 3 \frac{19}{20} , 3 \frac{1}{2}

Good luck and hope this helps! :)

What is the probability of rolling a 1 with a number cube that has the numbers 1, 2, 3, 4, 5, and 6 and tossing heads with a coi
Helga [31]
Probablity is (desired outcomes)/(total) possible outcomes so the dice 1 is desired and the total poassible outcomes is 6 since 6 numbers so probailty of rolling a 1 is 1/6 then flippin heads desired outcome=1 total possible=2 probabilty is 1/2 so we have 1/6 and 1/2 now we mulitply them 1/6 times 1/2=1/12 the answer is A
