3+c - (4+c) any1 simplfy?

kati45 [8]

3+c - (4+c)

pretend that there is a -1 in front of the bracket

3+c-1(4+c)

multiply the bracket by -1

(-1)(4)=-4

(-1)(c)=-c

3+c-4-c

3-4+c-c ( combine like terms)

+c-c=0

3-4=-1

-1+0=-1

Answer:

-1

Solve the word problem. Round your final result to the nearest hundredth.

fenix001 [56]

Answer:

1)Area of circle: 64 $\pi$

2)Area of semicircles: 128 $\pi$

3)Area of quarter-circles: 128 $\pi$

4)Total area of pattern: 320 $\pi$

Step-by-step explanation:

r = 8cm

Given: 1 circle, 4 semicircles, and 8 quarter-circles.

Area of a circle: $\pi r^{2}$

1) A = $\pi r^{2}$ where r = 8

A = 64 $\pi$

2) 4 semicircles = 2 circles

so the answer is 2*A = 128 $\pi$

3) 8 quarter-circles = 2 circles

Therefore, the answer here is the same as the answer for #2!

4)There are 5 circles total because:

1 circle = 1 circle

4 semicircles divided by 2 = 2 circles (because $\frac{1}{2}$ times 4)

8 quarter-circles divided by 4 (think about what "quarter" means) = 2 circles

So ... 1 + 2 + 2 = 5 circles

Now we need to find the area of 5 circles which is just 5*A

5*A = 320 $\pi$

The sum of two numbers is 46 . the larger number is 12 more than the smaller number. what are the numbers?

snow_tiger [21]

X + y = 46
x = y + 12

y + 12 + y = 46
2y + 12 = 46
2y = 46 - 12
2y = 34
y = 34/2
y = 17

x = y + 12
x = 17 + 12
x = 29

so ur 2 numbers are : 29 and 17

A grain silo has a diameter of 4.4 meters. The height of its cylindrical portion is 6.2 meters.

erastova [34]

Volume of a cylinder = Height x base are
H = 6.2 m
Bae are = π.R² ; Diameter =4.4 m, then Radius = 2.2 m
Base area = π(2.2)²
And Volume=:
V= (6.2).(π,2.2²) = (6.2).(π)(.4.84) = 30.008.π ≈ 94.2 m³
