Answer: 3
Explanation:
She wants to get 70%, so we need to solve
x/20 = 70/100
Doing so gets us
100x = 20*70
100x = 1400
x = 1400/100
x = 14
She needs to have 14 questions correct, out of 20, to get a score of 70%
14/20 = 0.70 = 70%
She needs to get 14-11 = 3 more correct questions.
Answer:
24.3
Step-by-step explanation:
We need to follow the order of operations PEMDAS:
- Parentheses
- Exponents
- Multiplication and Division (from left to right)
- Addition and Subtraction (from left to right)
Carry out the operation in the parentheses first:
3³ + 14.7 ÷ 7 - (1.2 × 4)
⇒ 3³ + 14.7 ÷ 7 - 4.8
Now the exponent:
⇒ 3³ + 14.7 ÷ 7 - 4.8
⇒ (3 × 3 × 3) + 14.7 ÷ 7 - 4.8
⇒ 27 + 14.7 ÷ 7 - 4.8
Now, the division (there is no multiplication):
⇒ 27 + 14.7 ÷ 7 - 4.8
⇒ 27 + 2.1 - 4.8
Finally, carry out the addition and subtraction (from left to right)
⇒ 27 + 2.1 - 4.8
⇒ 29.1 - 4.8
⇒ 24.3
10+10=20, 15+5=20 Those are both addition sentences that have a sum of 20.
Answer:
the real part is 80
the imaginary part is -60
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
As you can observe from the pattern, the numerator gets multiplied by 4 every increase in the sequence.
So , clearly, the 5th term will be = 
and the 6th term will be = 
Therefore , D will be the answer.
