Solve for all values of x (x+9)2=4

serg [7]

Answer:

x = -7

Step-by-step explanation:

you have to distribute the 2 to what is in the parenthesis, then you get left with 2x+18=4 so subtract the 18 from both sides leaving you with 2x=-14 so you divide both by 2 leaving you with x=-7.

Find m a 24.7 b 79.2 c 68.3 d 57.4 e 46.5 f 80.1 g 35.6

kogti [31]

Answer:

68.3 degrees

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

tan I = opp side / adj side

tan I = sqrt(82) / sqrt(13)

tan I = sqrt(82/13)

Taking the inverse tan of each side

tan ^-1 ( tan I) = tan ^-1( sqrt(82/13))

I = 68.2892

Rounding to the nearest tenth

I = 68.3 degrees

A box of cereal states that there are 75 calories in a 34-cup serving. What is the unit rate for calories per cup? How many calo

xeze [42]

The unit rate is how many calories are in 1 cup of cereal.
Set up a proportion:
$\frac{75 cal}{3/4 cup} = \frac{X cal}{1 cup}$
Cross multiply and solve:
$\frac{3}{4} X = 75\\ 3X=300\\X=100$
There are 100 calories per cup of cereal.

To get the calories in 4 cups of cereal, simply multiply the unit rate of 100cals/cup by 4.
$100*4=400$
There are 400 calories in 4 cups of cereal.
