Answer:

Angles in a triangle add up to 180.

ABG - x + 90 + ANGLE AGB = 180

Angles on a straight add up to 180.

CDE - 8x + ANGLE D + 3x = 180

Alterate angles - ATTACHMENT

ANGLE D = x

8x + x + 3x = 180

12x = 180

In a second period class, 37.5% of students like to bowl. in a fifth period class, 12 out of 29 students like to bowl. in which
Ierofanga [76]

The fifth period class has a greater fraction of students that like to bowl.

Any number in the form of p/q where p and q are integers and q is not equal to 0 is a rational number. Examples of rational numbers are 1/2, -3/4, 0.3, or 3/10.

Here we have,

In second period, 37.5% students like to bowl

∴, 37.5% = 37.5/100

= 375/1000

= 0.375 students like to bowl in second period

And in fifth period, 12 students out of 29 like to bowl

Therefore, 12/29 = 0.413 students like to bowl in fifth period

Hence, on comparison

0.375 < 0.413

= 375/1000 < 12/29

Thus, fifth period class has a greater fraction of student that like to bowl as compared to second period class.

What is the real interest rate if the nominal interest rate is 1 when the rate of inflation is 2
vovikov84 [41]

Answer:

Real interest rate = -1%

Step-by-step explanation:

Real interest rate=Nominal interest rate - inflation rate

From the above,

Nominal interest rate=1%

Inflation rate=2%

Real interest rate=Nominal interest rate - inflation rate

=1% - 2%

= -1%

Real interest rate = -1%

Real interest rate shows you what it really costs borrowers to pay back their loans.

if the real interest rate is greater than zero, the amount you pay back is worth more in real terms than the money you borrowed.

if the real interest rate is below zero as in the above case, the amount you will pay back is less worth in real terms than the money you borrowed.
