What is the sum of the first 10 positive integers? A) 55 B) 50 C) 100 D) 95

1 answer:

4 0

The correct answer here is A) 55. This is because a positive integer is defined as any number greater than 0 and has no decimals/ fractions in it. Therefore, you would add 1+2+3+4+5+6+7+8+9+10, yielding 55 as your answer.

The air Temperature is -12C at sunrise and rises 4 degrees c every hour for several hours the air temperature after x hours is r

Stolb23 [73]

Let f(x) = y.

y = 4x - 12

Let x = 0

y = 4(0) - 12

y = - 12

This leads to the point (0, -12).

Let y = 0.

0 = 4x - 12

1 2 = 4x

12/4 = x

3 = x

This leads to the point (3, 0).

We now graph both points and then connect each point with a straight line.

A circular swimming pool has a diameter of the 26 feet. What is the area of the swimming pool? Use 3.14 to approximate for π . E

inn [45]

So the equation for the area of a circle is $A=3.14(r^2)$

First to find the radius, you would need to divide the diameter, 26, by half, which in this case its 13.

Replace the r variable with 13 and solve:

$A=3.14(13^2)$

$A=3.14(169)$

$A=530.7$

Alenkasestr [34]

Answer:

C) 253. 3 cm²

Step-by-step explanation:

1. Sector area formula can be in degrees or radians. I will use degrees because we are given 240 degrees as a unit.

2. SA= $\frac{x}{360}$ times $\pi r^{2}$ where x is the degrees of the sector
