Answer:

See below

Step-by-step explanation:

Problem 9:

Yes it is proportional because the vehicle is moving at a constant speed of 41 mph (as 92/2=41). So if you don't drive, your speed is 0 mph which is accurate in regards to the graph.

Problem 10:

No it is not because due to the y-intercept not being 0, y doesn't vary directly with x. However, the slope remains constant, but it's not the same thing as proportional

A bolt has 6 1/2 turns per inch. How many turns would be in 2 1/2 inches of threads?
Reika [66]

There would be 41 1/4 turns in 2 1/2 inches of threads.

Given, number of turns a bolt has = 16 1/2 turns per inch.

per inch bolt turns = 16 1/2 =33/2

how many turns would be there in 2 1/2 inches of threads = ?

Threads Per Inch, or TPI, is a measure of how many threads are found in one inch along a fastener's length. American fasteners are the only ones that employ TPI. Typically, the thread count is higher for smaller fasteners since they have finer threads. Just as the name implies, the Threads Per Inch (TPI) refers to the number of threads that run the length of a screw for one inch. The TPI of a screw can be easily calculated by simply counting the threads and dividing the total length.

so, 5/2 inches bolt turns =33/2 x 5/2

=165/4

hence 41 1/4 turns

Therefore, 2 1/2 inches of threads have 41 1/2 turns.

Lana71 [14]

Answer:

She will spend over 10 pounds on candy.

Step-by-step explanation:

You have to multiply 6(the amount of money for each candy) with whatever number equals 60(the total she will spend) which is 10(the amount of pounds she is buying) so she will spend more than 10 pounds.

Ex.        

         6×10=60

EXPERT HELP: I'LL GIVE BRAINLIEST:
Shtirlitz [24]

Answer:

A. 355 Square inches

Step-by-step explanation:

Multiply length (l) x width (w) on each section. 45x5 = 225

10 x 10 = 100 and 6 x 10 = 60/2 = 30 (since it is a triangle you divide by two)

Add them all up, 225 + 100 + 30 = 355 square inches

What number has 7 ten thousands, 1 thousand, 1 hundred, and no ones?
FrozenT [24]

Answer:

71,100

Step-by-step explanation:

If you are trying to find a number that is written in word form, we can just use place values to find what goes where.

A number is broken down into this:

Ten thousands, thousands, hundreds, tens, ones.

If they have 7 ten thousands, the first digit will be a 7.

If they have 1 thousand, the second digit will be a 1.

If they have 1 hundred, the third digit will be a 1.

Since nothing is stated about tens, we assume it's value is 0.

And since there are no ones, it's value is 0.

So:

71,100.

Hope this helped!
