A3 Math gr6 20-21 Form O Online 21 of 34Item s Ali writes the expression "half of the sum of $9$ and a number." Write an algebraic expression that is equivalent to Ali's expression. Write a second algebraic expression that is different from, but equivalent to, your first expression.
Answer: See explanation
Step-by-step explanation:
We are informed that we should write a equation that represents the expression "Ali writes the expression "half of the sum of $9 and a number.".
Let the number be represented by x. The first equation based on the information given will be:
= 1/2(9 + x)
The second equation will be:
= (9 + x)/2
= 4.5 + 0.5x

3. In a thunderstorm, the wind velocity in meters per second can be described by the function
v(p)=5.7998−p‾‾‾‾‾‾‾√,
where
p
is the air pressure in millibars. What is the air pressure of a thunderstorm in which the wind velocity is 49.3 meters per second? Round your answer to the nearest tenth of a millibar.
Answer:
p = 923.2 millibar
Step-by-step explanation:
Given that,
The wind velocity can be described by the function as follows :
[tex]v(p)=5.7\sqrt{998-p}[/tex]
Where
p is the air pressure in millibar
Put v = 49.3 m/s in the above function.
[tex]49.3=5.7\sqrt{998-p}[/tex]
Squaring both sides,
[tex]49.3^2=(5.7\sqrt{998-p})^2\\\\2430.49=32.49(998-p)\\\\\dfrac{2430.49}{32.49}=(998-p)\\\\74.80=(998-p)\\\\p=998-74.80\\\\p=923.2\ mbar[/tex]
So, the required pressure is equal to 923.2 millibar.

Wendy borrowed a 400-page book from the library. She read 50 pages. The book is due in 5 days. Complete the inequality to find x, the number of pages Wendy must read to finish the book ?
Answer:
350 Pages or 70 pages a day
Step-by-step explanation:
If the book is 400 pages long and she already read 50 pages she only needs to read 350 pages.
Gail runs a taxi.
Her running costs are £95 per day.
She charges £1.40 per mile travelled.
On Tuesday she carried passengers for a total of 50 miles.
What was her total loss?
Answer:
Her total loss was £25
Step-by-step explanation:
Here, we want to get the value of total loss
What we have to do here is to subtract the amount made from the running cost
From the question, we have the amount made as;
£1.40 * 50 = £70
So we have the loss as,
70-95 = -£25

In a geometric sequence, the first term is 3 and the common ratio is 2. What is the sum of the first 9 terms?
a .99
b. 1022
c. 1533
d. 765
Step-by-step explanation:
99 is the answer........
The sum of the first 9 terms of the given GP series will be 1533 thus option (c ) is correct.
What is geometrical progression series?A geometric progression is a sequence in which any element after the first is obtained by multiplying the previous element by a constant which is called a common ratio denoted by r.
For example, the sequence 1, 4, 16, 64,… is a geometric sequence with a common ratio of r = 4.
Let's say the first term of the given GP is a and the common ratio is r.
a = 3 and r = 2
The Sum of n term is given as,
S = a([tex]r^{n}[/tex] - 1) / (r - 1)
S₉ = [3(2⁹ - 1)/(2 - 1)]
S₉ = 1533
Hence "The sum of the first 9 terms of the given GP series will be 1533".

Answer:
∡ a = 80°
Step-by-step explanation:
the sum of the interior angles of a triangle is 180 degrees
a + 30 + 70 = 180
a + 100 = 180
a = 80
Answer:
80 Degrees
Step-by-step explanation:
A triangle equals 180 degrees when all sides are added together, so here we need to first add the angles of the ones we have available.
30 + 70 = 100
Now, we subtract to find out how much more we need...
180 - 100 = 80

A sapling that started out 13.63 inches tall grew 2.41 inches per year. How tall was the sapling when it was 14 years old?
Answer:
47.37 Inches
Step-by-step explanation:
We start by assuming that we're at zero years when the tree is at 13.63 inches. We then ignore that height, and look at the rate of growth, which is 2.41 in / year.
The question asks how tall the tree is when it's 14 years old, so we multiply 2.41 inches / year by 14 years to get 33.74 inches.
The final step is to add that 33.74 onto the original 13.63 to get a new total of 47.37 inches when the sapling is 14 years old.
