I think the answer is B) \frac{3}{8}. You can figure this out by multiplying the possible outcomes of the coin by the spinner (4*2) and find the amount of outcomes that are not what you are looking for (3) and put that over the product. (3/8)

Hope this helps

AB:BD = 3:4 <br><br> AC:CD = 3:2 <br><br> Work out AB:BC:CD
Papessa [141]

Answer:

15:6:14

Step-by-step explanation:

AB:BD is split into a total of 3+4=7 parts.

AC:CD is split into a total of 3+2=5 parts.

So, if the two ratios are put on a number line together with the points A, B, C, and D, the number line would be split into a total of 35 parts (the LCM of 7 and 5).

AB would be (3/7)*35=15.

CD would be (2/5)*35=14

BC would be 35-(15+14)=6

So, the ratio is 15:6:14.

Gloria received a 4 percent raise and is now making $24,960 a year, what was her salary before the raise?
Svetradugi [14.3K]

She gets a 4% raise so her new pay is 100% + 4% of her previous pay.

104% = 1.04 as a decimal.

Divide her new pay by 1.04:

24,960 / 1.04 = 24,000

Her previous pay was $24,000

Nataliya [291]

Answer:

The  fraction of the children in the group that contains both dog and a cat is \frac{17}{12}

Step-by-step explanation:

The fraction of the children in the group that contains both dog and a cat is presented below:

= Pet dog + cat

= \frac{2}{3} + \frac{3}{4}\\\\= \frac{8 + 9}{12}   \\\\= \frac{17}{12}

Hence, the fraction of the children in the group that contains both dog and a cat is \frac{17}{12}
