Three consecutive even integers are such that the square of the third is 76 more than the square of the second. Find the three i

Arada [10]

Let n represent the interger l, the three consective intergers are represented by

$n$

$n + 2$

$n + 4$

The second one represent

$(n + 2) {}^{2} + 76 =( n + 4) {}^{2}$

Simplify both sides

$n {}^{2} + 4n + 4 + 76 = {n}^{2} + 8n + 16$

${n}^{2} + 4n + 4 = {n}^{2} + 8n - 60$

$4n + 4 = 8n - 60$

$4n + 64= 8n$

$64= 4n$

$n = 16$

The intergers are 16,18,20

Simplify cube root of 7 over fifth root of 7.

Paha777 [63]

$\bf a^{\frac{ n}{ m}} \implies \sqrt[ m]{a^ n} \qquad \qquad \sqrt[ m]{a^ n}\implies a^{\frac{ n}{ m}}\\\\[-0.35em] \rule{31em}{0.25pt}\\\\ \cfrac{\sqrt[3]{7}}{\sqrt[5]{7}}\implies \cfrac{\sqrt[3]{7^1}}{\sqrt[5]{7^1}}\implies \cfrac{7^{\frac{1}{3}}}{7^{\frac{1}{5}}}\implies 7^{\frac{1}{3}}\cdot 7^{-\frac{1}{5}}\implies 7^{\frac{1}{3}-\frac{1}{5}} \\\\\\ 7^{\frac{5-3}{15}}\implies 7^{\frac{2}{15}}$

Alan works at a gym. One week he records the number of people to visit the gym each day. The mean average for Monday to Friday i

stellarik [79]

Answer:

146 people

Step-by-step explanation:

The formula for mean = sum of values/number of values

For Monday to Friday , the average number of people that came = 98

Hence, the total number of people that came is calculated as:

Number of people that attended Monday to Friday = 98 × 5 = 490 people

The number of people that came on Saturday = 162 people

The mean average for the whole week is 114.

The number of days in a week = 7 days

The number of people that came in on Sunday is represented = x

Therefore,

490 + 162 + x/7 = 114

Cross Multiply

652 + x = 798

x = 798 - 652

x = 146 people

Therefore, 146 people visited on Sunday
