Answer:

391,660.6

Step-by-step explanation:

First we need to do what is in the parentheses. 56/23 equals 2.4. 4234 + 2.4 is 4236.4...  4236.4 times 94 is 398,221.6... Now 9 to the fourth power is 6561. x + 6561 is 398,221.6 so x equals 391,660.6... I hope this helps and please make me the brainliest. Thanks!

A sector with an area of 26pie cm^2 has a radius of 6 cm. What is the central angle measure of the sector in radians?
Zolol [24]

Answer:

The central angle measure of the sector in radians is \theta=\frac{13}{9}.

Step-by-step explanation:

A sector of a circle is the portion of a circle enclosed by two radii and an arc. It resembles a "pizza" slice.

The area of a sector when the central angle is in radians is given by

                                                    A=(\frac{\theta}{2})\cdot r^2

where

r = radius

θ = central angle in radians

We know that the area of the sector is 26 \:cm^2 and the radius is 6 cm. Applying the above formula and solving for the central angle (\theta) we get that

                                                   26=(\frac{\theta}{2})\cdot (6)^2\\\\\left(\frac{\theta}{2}\right)\left(6\right)^2=26\\\\\frac{\frac{\theta}{2}\cdot \:6^2}{36}=\frac{26}{36}\\\\\frac{\theta}{2}=\frac{13}{18}\\\\\theta=\frac{13}{9}

A school bought pens, each costing $1, and pencils, each costing $0.5. The cost of the whole purchase was $220. How many pens an
Levart [38]

Answer:

200 pencils and 120 pens

Step-by-step explanation:

Let the number of pencils be x while pens be y.

Considering the cost of whole purchase then, we get the equation

0.5x+y=220

Considering the number of items bought, then the equation is

x-y=80

Adding the two equations then we have

1.5x=300

x=300/1.5=200

Consideeing that x-y=80 and x is 200 then

200-y=80

y=200-80=120

Therefore, the pencils were 200 and pens 120 pieces

The sum of three consecutive even integers is 36. Let x represent the least consecutive integer.
lubasha [3.4K]
The integers are x, x + 2 and x + 4

x + x + 2 + x + 4 = 36
3x + 6 = 72
3x = 36 - 6 = 30
x = 30/3 = 10

The least numbers is 10
Therefore, the numbers are 10, 12 and 14
