Answer:

y=21

Step-by-step explanation:

y= 9 cos x =3 so y=3 when x=1 on the base level so if x=7 would be x=1 on the base level * 7 then y=3 on the base level * 7 would be y = 21

OLga [1]

Answer:

<u>There are 60 toddlers in the preschool class</u>

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Percentage of the toddlers in a preschool class drink water with their lunch = 5

Number of the toddlers in a preschool class drink water with their lunch = 3

2.  How many toddlers are in the class?

We'll solve the question, using the Direct Rule of Three, this way:

Percentage      Toddlers

      5                       3

    100                     x

*******************************

5x = 3 *100

5x = 300

x = 300/5

x = 60

<u>There are 60 toddlers in the preschool class</u>

Can someone please help me?
larisa86 [58]

We know that a triangle equals 180 degrees in total. We also know one of the angles so we can do 180-84= 96. This means that the other two angles must be equal to 96 degrees. We then set up (x+59)+(x+51)=96 "since both of the angles must add up to 96." Then we add like terms and get 2x+110=96. Further simplification gives us x= -7. Plug this into both angles and you get that angle A is 44 degrees.

A bus travels at a constant speed of 48 km/h. How long will it take to travel 600 km?
grigory [225]

Answer:

It will take 12 and 30 hours

Step-by-step explanation:

To solve this, you need to divide by <u>distance needed to travel by the speed</u>

600/48 is equal to 12.5 hours.

.5 hours is equal to 30 mins because 60mins times .5 is 30 minutes, therefore <u>the final answer is 12.5 hours</u>

I hope this helps :)

Answer:

  • The initial value corresponds to the y value when x = 0

Step-by-step explanation:

Since the graph is given, it is unnecessary to "finish the line." It is only necessary to read the value of y from the graph where x=0.
