Answer:

A. Cylinder + cone

<u>Volume is the sum of volumes:</u>

  • V = Vcon + Vcyl = 1/3πr²h₁ + πr²h₂
  • V = 1/3π*9²*12 + π*9²*120 = 31554.2 cm³

<u>Surface area of cone:</u>

  • A = A=πr(r+√(h₁²+r²)) = π*9(9 + √(9²+12²)) = 678.6 cm²

<u>Surface area of cylinder minus bases:</u>

  • A = 2πrh₂ = 2π*9*120 = 6785.8 cm²

<u>Total surface area:</u>

  • 678.6 + 6785.8 = 7464.4 cm²

-------------------------------------------------

B. Cube+ pyramid

<u>Volume:</u>

  • V = a³ + (1/3)a²h = a³ + (1/3)a²√(l²-(a/2)²)
  • V = 8³ + (1/3)8²√(10²-4²) = 707.5 cm³

<u>Surface area of pyramid:</u>

  • A = a² + 2al = 8² + 2*8*10 = 224 cm²

<u>Surface area of cube minus bases:</u>

  • A = 4a² = 4(8²) = 256 cm²

<u>Total surface area:</u>

  • A = 224 + 256 = 480 cm²

A toothbrush and toothpaste cost one dollar and ten cents total. The toothbrush costs a dollar more than the toothpaste. How muc
Aleks [24]
Cost of the toothbrush and the toothpaste together = $1.10
Let us assume the cost of the toothpaste = x
Then
The cost of the toothbrush is = (x + 1) dollar
Then we can write the equation as
x + x+ 1 = 1.10
2x + 1 = 1.10
2x = 1.10 - 1
2x = 0.10
x = 0.10/2
  = .05 dollars
So the cost of the toothpaste is 0.05 dollars.<span>I hope the procedure is clear to you.</span>

A cell phone company charges a monthly rate of $10.00 and $0.20 a minute per call. Write an equation that can be used to determi
Aleks04 [339]

Answer:

y = 0.20m + 10, 100 minutes

Step-by-step explanation:

Equation: y = mx + b

Fill it in.

m = slope = 0.20

b = y-intercept = 10

y = 0.20x + 10 (They wanted the variable to be m. So, changing that.)

y = 0.20m + 10

Fill in.

30 = 0.20m + 10

Solve.

20 = 0.20m

100 = m

She was on the phone for 100 minutes.

Solve the equations. 1. 21-9 = 2.35 - 15 = 3.30 - 25 = 4.40 - 10 = 5.30 - 20 = 11.34 - 20 = 12. 22 - 12 = 13.30 - 10 = 14. 19-9-
STALIN [3.7K]
1. 29 - 9 = 20
2. 35 - 15= 20
3. 30 - 25= 5
4. 40 - 10= 30
5. 30 - 20= 10
11. 34 - 20= 14
12. 22 - 12=10
13. 30-10=20
14. 19-9 = 10
15. 28 - 12 = 16

I hope this helps. Imk if this what your asking. Have a good day!! :)
