Answer:

The lenght of the tree sides of the triangle are:

first side: 21 inches

second side: 19 inches

third side: 33 inches

Step-by-step explanation:

a + b + c = 73

b = a - 2

c = a + 12

a = leght of the first side of the triangle

b = lenght of the second side of the triangle

c = lenght of the third side of the triangle

then:

a + (a-2) + (a+12) = 73

3a - 2 + 12 = 73

3a + 10 = 73

3a = 73 - 10

3a = 63

a = 63/3

a = 21 inches

b = a - 2

b = 21 - 2

b = 19 inches

c = a + 12

c = 21 + 12

c = 33 inches

Check:

21 + 19 + 33 = 73

kipiarov [429]

Answer:

Katherine need to work minimum 10 hours lifeguarding to meet her requirements

Step-by-step explanation:

Given:

Rate for Lifeguarding = $16\ per\ hour

Rate for walking dogs = $6 \ per\ hour

She had worked 2 hours walking dog

Money for walking dogs = Rate for walking dogs\times hours worked=\$6\times2=\$12

she can work a maximum of 15 total hours and must earn at least $160.

Let hours required for lifeguarding be x

Money for life guarding = Rate for walking dogs\times hours worked for lifrguarding= \$16 \timesx=16x

Total Money she must earn = Money for lifeguarding + Money for walking dogs

16x+12=160\\16x=160-12\\16x=148\\x=\frac{148}{16}=9.25 \ hours

Rounding to nearest hour

Katherine need to work minimum 10 hours lifeguarding to meet her requirements

Scientific notation: We moved the decimal 5 times to the right, and in order to put the number back in standard form, we have to move the decimal 5 times to the left. So the scientific way of saying this is 9.62 x 10⁻⁵
