Answer: 121 2/3 days

Step-by-step explanation:

Number of days in a year = 365 days

Number of friends = 3 friends

The number of days each year that Alisa need to walk the dog will be:

= Number of days in a year / Number of friends.

= 365 / 3

= 121 2/3 days

= 121 days + (2/3 × 24hours)

= 121 days 16 hours

Note that 24 hours = 1 day

Question 9
andreyandreev [35.5K]

Answer:

4n = 24

Step-by-step explanation:

Given

Cars = 4

Empty = 3

Occupied = 21

Required

Determine an equation to find number of seats

Let the number of seats in each car be represented by n;

If 1\ car = n

Then:

4\ cars = 4 * n

4\ cars = 4 n

This implies that there are 4n total seats

Solving further:

Occupied\ Seats + Empty\ Seats = Total

Substitute values for the above parameters:

21 + 3 = 4n

24 = 4n

Reorder

4n = 24 ---- This equation can be used to solve for n

An angle measures 156° less than the measure of its supplementary angle. What is the measure of each angle?
GrogVix [38]

Answer:

12° and 168°

Step-by-step explanation:

If x is the angle, and y is the supplementary angle, then:

x + y = 180

x = y − 156

Solve the system of equations using substitution:

y − 156 + y = 180

2y = 336

y = 168

Plug back into either equation to find x:

x = 12

Answer:

<h2><em><u>Option</u></em><em><u> </u></em><em><u>B</u></em><em><u>:</u></em></h2><h3><em><u>112</u></em><em><u> </u></em><em><u>families</u></em><em><u> </u></em></h3>

Step-by-step explanation:

<em><u>Given</u></em><em><u>,</u></em>

No. of families = 75

Out of 75 no. of families had cars = 42

Out of 1, no. of families can have cars

=  \frac{42}{75}

<em><u>Therefore</u></em><em><u>, </u></em>

Out of 200 families, no. of families had cars

= 200 \times  \frac{42}{75}

=200 \times   \frac{14}{25}

= 8 × 14

= 112

<em><u>Hence</u></em><em><u>, </u></em>
