Evaluate the expression. [(8 x 7) – 2): 9

frozen [14]

Answer:

☑ Answer is 6

Step-by-step explanation:

${ \tt{ \{(8 \times 7) - 2 \} : 9}} \\ = { \tt{(56 - 2) :9 }} \\ = { \tt{54 :9 }}$

» But this is a ratio, so it can be expressed in terms of fractions:

$= { \tt{ \frac{54}{9} }} \\$

» Divide both the denominator and numerator by 9:

${ \tt{ = \frac{54 \div 9}{9 \div 9} }} \\ \\ = { \tt{ \frac{6}{1} }} \\ \\ = 6$

Ill Mark Brainliest if you answer correctly. The figure below shows a shaded circular region inside a larger circle:

pogonyaev

First we have to find the areas of both circle using the formula

$Area = \pi r^2$

For larger circle,

$Area= \pi(5)^2 = 25 \pi$

For smaller circle,

$Area = \pi (4)^2 = 16 \pi$

Required probability

$= \frac{25 \pi -16 \pi}{25 \pi} *100 = \frac{9}{25}*100 = 36%$

Correct option is the second option .

Step-by-step explanation:

Since this is only three terms

Find the three terms and add

j=1 3(1)^2+1 = 3+1 =4

j=2 3(2)^2+1 = 3(4)+1 =13

j=3 3(9)^2+1 = 27+1 =28

The sum is 4+13+28 =45
