This is an incomplete question, here is a complete question.
A hurricane wind blows across a 7.00 m × 12.0 m flat roof at a speed of 150 km/h.
What is the pressure difference Δp = p(inside)-p(outside)? Use 1.28 kg/m³ for the density of air. Treat the air as an ideal fluid obeying Bernoulli's equation.
Answer : The pressure difference will be, 
Step-by-step explanation :
As we are given:
Speed = 150 km/h = 41.66 m/s
Density = 
Area = A = 7.00 m × 12.0 m
Formula used :
Now put all the given values in this formula, we get:
Thus, the pressure difference will be,
Total points is 23
<u>Explanation:</u>
Given:
Total number of baskets = 18
Let the number of 2 pointer shots be x
Let the number of 3 pointer shots be y
According to the question:
-1
The equation can be formed as:
On solving this equation further we get:
Putting the value of x = 4 in equation 1
Points for 2 pointer shots = 4 X 2
= 8
Points for 3 pointer shots = 5 X 3
= 15
Total points = 8 + 15
= 23
Therefore, total points is 23
Answer:
He knows that 30÷5 is 6. He then multiplies 6 by 6 to get 36
Step-by-step explanation:
A is option is the best approach for him to find the answer.
Answer:
x = -2
Step-by-step explanation:
From x = -2 to x = 5, f' is negative. That means f is decreasing.
From x = 5 to x = 6, f' is positive. That means f is increasing.
The negative area (between x = -2 and x = 5) is larger than the positive area area (between x = 5 and x = 6). That means f decreases more than it increases.
So f is an absolute maximum at x = -2.
Ruby wants to <u>start</u> her own <u>business</u> taking photographs. She has to <u>purchase</u>
- photo printer for $251.99;
- lights for $150.00;
- photo paper for $30.98.
In total, she will use
$251.99 + $150.00 + $30.98 = $432.97.
If she has $840.32 in savings, then
$840.32 - $432.97 = $407.35 will remain.
Answer: she will use $432.97 - correct answer A
