y = t x 15 + 55


15 equals the rate of change or the constant of proportionality and 55 is equal to the y-intercept, or the number of stamps you originally had

Sean determines that the triangle shown in the diagram has angle measures of 40°, 40°, and 100°. Is Sean correct?

Answers

The bottom left angle is 180 -80=(100)

So the remaining 2 angles are equal 80
As all angles in a triangle are equal to 180

X+5 + x - 5 =80
Simplify
2x=80
X=40

Soo one of the angles are 40-5 which is (35)
And the other is 40+5 which is (45)
So sean is not correct
~sorry sean teehee

Answer:

Step-by-step explanation:

The two angles add to 80 degrees. Two remote angles always equal the exterior angle not connected to them.

That means that

x + 5 + x - 5 = 80

2x = 80

x = 40

The base angle  is

40 + 40 + y = 180

80 + y = 180

y = 100

Note

You could do this much quicker by noticing that

80 + y = 189

y = 100

No he is not right

The given 2 angles are x + 5 which is 45 and x - 5 which is 35

All he got correct was the fact that the third angle is 100 degrees.

Tanya is training a turtle for a turtle race. For every 1/2 of an hour that the turtle is crawling, he can travel 2/23 of a mile. At what rate is the turtle crawling in miles per hour?

Answers

Answer:

To determine at what unit rate the turtle is crawling, divide 3/20 mile by 1/6 hour.

Therefore, the unit rate is 9/10 of a mile per hour

Step-by-step explanation:

The rate of turtle crawling is 4/23 miles per hour.

Given that, the time taken by turtle to crawl = 1/2 hour and number miles crawled by turtle = 2/23 mile

What is the speed?

The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.

Now, Speed = Distance/Time

= 2/23 ÷ 1/2

= 2/23 × 2/1

= 4/23 miles per hour

Hence, the rate of turtle crawling is 4/23 miles per hour.

(8c2-9c2) =-c2
then add them all together.
-8c2-7c2-c2
since they’re all negative you can add them together but don’t forget the negative.
8+7=15
