Answer:

-122.5

Step-by-step explanation:

Difference = 7 - 4 = 3 terms; 8.75 - (-70) = 78.75

1 term → 78.75/3 = 26.25

therefore, u2 = - 70 - 2(26.25) = -122.5

Matthew made a fruit salad, in which the ratio of blueberries to red grapes is 8:6. If Matthew used 28 blueberries, how many red
Inga [223]

Answer:

Step-by-step explanation:

Let's look at some other ratios that equal 8:6  We could increase them or decrease them.  For instance if we cut one in half we cut the other one in half, so 8:6 would be the same ratio as 4:3.  With the same thinking if we double one we double the other so 8:6 s the same ratio as  16:12.  Now, we want to go from 8 to 28.  What do we multiply 8 by to get to it?  Or, it might be easier to use 4:3 and see what you multiply 4 by.  Then you multiply 3 by that same number to get the other number.

Let me know if that doesn't make sense.

If A = 30° and r = 12, find x. (Round your answer to the nearest whole number.)
Margaret [11]

Answer:

\boxed{12}

Step-by-step explanation:

A = 30° and r = 12

\sin A = \frac{r}{r + x}

\sin 30 = \frac{12}{12 + x}

\frac{1}{2} = \frac{12}{12 + x}

1(12 + x) = 2(12)

12 + x = 24

x = 24 - 12

x = 12

.

Happy to help :)
