Find the missing angle. A.65 B.75 C.70 D.85

vovangra [49]

The answer is c because every quadrilateral adds up to 360 so when you add all the numbers you get 290 and when you subtract 360-290 is 70.

egoroff_w [7]

Answer:

$\frac{31}{50}$

Step-by-step explanation:

percentage of graduates with loan = 62%

total sample = 50

Number of student in the sample with student loan

= (percentage of graduates with loan) x (total sample)

= 62% x 50

= 31

Proportion of student in the sample with student loan = $\frac{31}{50}$

1/16^3x=64^2(x+8) Solve for x.

SSSSS [86.1K]

Answer:

x = -4

Step-by-step explanation:

16 = 4*4 = 4²

64 = 4 * 4* 4 = 4³

$(\dfrac{1}{16})^{3x}=64^{2*(x+8)}\\\\\\(16^{-1})^{3x}=64^{2x + 16}\\\\\\16^{-3x}=64^{2x +16}\\\\(4^{2})^{-3x}=(4^{3})^{2x+16}\\\\4^{-6x}=4^{6x +48}$

As bases are same, compare exponents

6x + 48 = -6x

Subtract 48 from both sides

6x = -6x - 48

Add '6x' to both sides

6x + 6x = -48

12x = -48

Divide both sides by 12

x = -48/12

x = -4

How do I do #1 ? Help!!

juin [17]

1) First find the multiplier.

Look at the 0 and 1st term you have 5 as the 0 and 3 as the 1st term.

2)Ask how do we get from 5 to 3?

We subtract 2 so the multiplier is -2

3)Lets make a linear equation: y=mx +b

m= multiplier or slope
x= Just equals x value
b= your starting value or the 0 term which is 5

4)Use the values that you have to create your equation.

y=-2x +5

Note:For the x value just plug in the x value from your table.

Ex.

y=-2(-10)+5

y=20+5
y=25
