The sum of a number y and 9 is a least -1

Mathematics
1 answer:
Nataly_w [17]4 years ago

Answer:

Y+9>= -1

Step-by-step explanation:

The sum of a number y and 9 means that we wanna add Y and 9, but since y is a variable and 9 is just a number, we can't add them.

Now we have Y+9

Now, we plug in our inequality sign which is at least.

at least is >=

Now we have Y+9>=

And all you have to do is place the negative one after the inequality sign, and you get Y+9>= -1

Hope this helps! :)

alexandr1967 [171]

Question 1: If shes making 4 hats alone and then Quadruples it shes making 16 hats per week if she quadruples it again she will be knitting 64 hats per week.

4x4=16

16x4=64hats

Question 2: There is an error because 5x5x5 = 5³

Question 3: 2⁴ - 8 x 2 / 4 = 12

2⁴ = 16  - 8 x 2 / 4

8x2 = 16

16/4 = 4

16-4 = 12

The car at each vertex of a Ferris wheel holds a maximum of 5 people. The sum of the measures of the angles of the Ferris wheel
larisa [96]

Answer:

225

Step-by-step explanation:

The sum total of all the angles is 7,740 degrees,

The formula for the interior angle is 180(n - 2) where n is the number of sides in the polygon

Set this equal to 7740

180 (n-2) = 7740

Divide each side by 180

 180/180 (n-2) = 7740/180

  n-2 =43

Add 2 to each side

n-2+2 = 43+2

n = 45

Each vertex hold 5 people so take n and multiply by 5

45*5 = 225

The Ferris wheel holds 225 people
