It has given you that to earn $85 in one week. Kim could earn $8 per hour babysitting and $15 per hour for yard work with work time limited to 8 hours per week. Now we have to represent the variable X is the numbers of hours spent doing babysitting in the week. And Y represents the number of hours spent doing yard work in the week. The equation representing the condition on the total number of hours to be worked is: x+y= 8. The equation relating the number of hours working at each job toward the fund- raising goal is: 8x+ 15y= 85 and your final answer should be x= 5

Licemer1 [7]

Angles in a parallelogram have to equal 360.

Let x represent the measurement of the unknown angle.

2(55) + 2x = 360
110 + 2x = 360
2x = 250
x = 125

How many integers are there that consist of four digits (from 1000 to 9999) where the first digit is a 5 or an 8 and the third d

Ostrovityanka [42]

Answer:

1600 integers

Step-by-step explanation:

Since we have a four digit number, there are four digit placements.

For the first digit, since there can either be a 5 or an 8, we have the arrangement as ²P₁ = 2 ways.

For the second digit, we have ten numbers to choose from, so we have ¹⁰P₁ = 10.

For the third digit, since it neither be a 5 or an 8, we have two less digit from the total of ten digits which is 10 - 2 = 8. So, the number of ways of arranging that is ⁸P₁ = 8.

For the last digit, we have ten numbers to choose from, so we have ¹⁰P₁ = 10.

So, the number of integers that can be formed are 2 × 10 × 8 × 10 = 20 × 80 = 1600 integers
