Answer:

4917

Step-by-step explanation:

Given sequence:

42, 43, 44, 45, ..., 107

This is AP with common difference of 1, the first term of 42 and the last term of 107

Number of terms:

107 - 42 + 1 = 66

Sum of the terms:

Sₙ= 1/2*n*(a₁+aₙ)

Sₙ= 1/2*66*(42+107) = 4917

Answer is: 4917

alexgriva [62]

Answer:

Perry's claim is correct while Karina is incorrect

Step-by-step explanation:

Question is incomplete (See Attachment)

First, we need to determine the area covered by Karina and Perry

For Karina, there are 9 square boxes each of which has an area of 1 unit sq

So:

$Karina = 9 * 1\ unit^2$

$Karina = 9\ unit^2$

For Perry:

There are 18 square boxes, each of which has an area of 1 unit sq.

So:

$Perry = 18 * 1\ unit^2$

$Perry = 18\ unit^2$

Comparing both areas, we can conclude that Perry's claim is correct while Karina is incorrect

Find volume of sphere in cubic yards whose radius is 5 yard Use pi = 3.14

enyata [817]

Answer:

523.333 cubic yards

Step-by-step explanation:

The formula for the volume of a sphere is $\frac{4}{3}\pi r^{3}$ where $r$ is the radius.

The radius of the given sphere is $r=5$ yards and $\pi =3.14$ .

Therefore, we can substitute in the radius and solve:

$V_{sphere}= \frac{4}{3}\*\times3.14\times 5^{3} =523.333$ cubic yards
