Answer:
8 and 1/4
Step-by-step explanation:
10 3/4 - 2 1/2
3/4 - 1/2 = 1/4
10 - 2 = 8
Answer:
X = savings, p= pay per hour
X+4p = 86 - - - - (1)
X+6p=104 - - - - - (2)
Re arrange equation (1)
X=86-4p-----(3)
Substitute (3) in (2)
86-4p +6p=104
86+2p=104. (subtract 86 from both side)
2p = 18. (divide by 2 from both side)
Then p =$9
By substitute in equation (1)
X = $50
Answer:
sorry say nice its out of understand
The given complex number is ⇒ z = a + b i
The absolute value of z = √( a² + b² ) = 3.28
So, we will check which of the options will give 3.28
<span>( A) IF ⇒⇒ a=1.5 and b=1.7
</span>
<span>∴ √( a² + b² ) = √( 1.5² + 1.7²) = √5.14 ≈ 2.27
</span>
===================================
<span>(B) IF ⇒⇒ a=1.5 and b=3.3
</span>
<span>∴ √( a² + b² ) = √(1.5² + 3.3²) = √13.14 ≈ 3.62
</span>
====================================
<span>(C) IF ⇒⇒ a=1.7 and b=2.8
</span>
<span>∴ √( a² + b² ) = √(1.7² + 2.8²) = √10.73 ≈ 3.28
</span>
====================================
<span>(D) IF ⇒⇒ a=2.8 and b=3.3
</span>
∴ √( a² + b² ) = √(2.8² + 3.3²) = √18.73 ≈ 4.33
=====================================
So, the correct answer is option (C) <span>a=1.7,b=2.8</span>
