Answer:

a_{7}=\frac{256}{729}   or   a_{7}=0.35

Step-by-step explanation:

a_{n} =a_{1}* r^{n-1}

a_{7}=4*\frac{2}{3}^{7-1}

a_{7}=4*\frac{2}{3}^{6}

a_{7}=4*\frac{64}{729}

a_{7}=\frac{256}{729}

or

a_{7}=0.35

Using the formula F=9/5C+32, find C when F= 75.
den301095 [7]

Answer:

DIVIDING 9 AND 5 = 23.8

9/5 FRACTION = 0.04

Step-by-step explanation:

If 9/5 means 9 divided by 5

FLIP THE EQUATION

9/5C + 32 = 75

9/5C + 32 - 32 = 75 -32

9/5C = 43

9/5 = 1.8

1.8C = 43

1.8C/1.8 = 4

If 9/5 means 9/5ths fraction

FLIP THE EQUATION

9/5C + 32 = 75

9/5C + 32 - 32 = 75 -32

9/5C = 43

9/5C / 9/5 = 43 / 9/5

C = 0.04

Hope this helps i thought 9/5 was 9 divide by 5. If it was 9/5 as a fraction i also made that equation too.
