elena-s [515]

Answer:

  a. 37

  b. 25

  c. 226

Step-by-step explanation:

Place value has the same meaning in any other number base that it has in base 10. Using expanded form is one way to do the required base conversion.

a. 122₅ = 1×5² +2×5¹ +2×5⁰

   = 25 +10 +2 = 37

__

b. 11001₂ = 1×2⁴ +1×2³ +0×2² +0×2¹ +1×2⁰

   = 16 +8 + 1 = 25

__

c. 16T₁₂ = 1×12² +6×12¹ +10×12⁰

   = 144 +72 +10 = 226

Answer:

x = 3.5

Step-by-step explanation:

Triangle to the right:

4^2 + x^2 = 8^2

16 + x^2 = 64

y^2 = 48

Triangle to the left:

x^2 + 6^2 = 48

x^2 + 36 = 48

x^2 = 12

x = sqrt(12)

Which of the following is equivalent to the inequality shown below?
VARVARA [1.3K]

Answer:

4x + 0.9 \geq 0.1 is equivalent to the inequality 40x+9 \geq 1

Step-by-step explanation:

Given inequality : 4x + 0.9 \geq 0.1

We are supposed to find Which of the following is equivalent to the inequality

4x + 0.9 \geq 0.1

\Rightarrow 4x+\frac{9}{10} \geq \frac{1}{10}

Multiply both sides by 10

\Rightarrow 4(10)x+\frac{9}{10}(10) \geq \frac{1}{10}(10)

\Rightarrow 40x+9 \geq 1

4x + 0.9 \geq 0.1 is equivalent to the inequality 40x+9 \geq 1

So, Option B is true

B) 40x+9 \geq 1
