salantis [7]

Tim's speed is 16/40 laps per minute, which simplifies to 2/5
Jim's speed is 30/75 laps per minute, which simplifies to 2/5
They walk at the same pace because 2/5=2/5, so neither of them.

Which polygon has interior angles whose sum is 1440°? octagon nonagon decagon 11-gon

ArbitrLikvidat [17]

Answer:

Decagon

Step-by-step explanation:

We can use the general equation to determine the sum of interior angles:

$I.A. = 180 \times (n-2)$

Since we know the sum of interior angles (I.A.) is 1440°, we must figure out n - the number of sides and so:

$1440=180(n-2)\\\\\frac{1440}{180}=n-2\\\\8=n-2\\\\n=10$

Since n=10 this means that it is a 10 sided shape meaning it's a decagon.

Let S = {1, 4, 6, 9}

tankabanditka [31]

Answer:

There are 8 sets B that satisfy the conditions.

Step-by-step explanation:

We have to find the total subsets of S that have 1 as an element.

Subsets B with one element: {1}

Subsets with two elements: {1,4}, {1,6}, {1, 9}

Subsets with three elements: {1,4,6}, {1,4,9}{1,6,9}

Subsets with four elements: {1,4,6,9}

Therefore, B = {1, {1,4}, {1,6}, {1, 9}, {1,4,6}, {1,4,9}, {1,6,9}, {1,4,6,9}}
