I think it’s C.
Hope this helps :)
Have a great day
The given in the problem above is an arithmetic sequence with the first term equal to 4 and the common difference is 5. To determine the number of seats on row 23, use the formula,
an = a1 + (n - 1) d
Solving for the 23rd term,
an = 4 + (22) 5 = 114 seats
Therefore, the answer is there are 114 seats on the 23rd row.
The answer is 17 yards.
So, the drawn length (l1) is 1/4 yard:
l1 = 1/4 yards
The actual fountain's length (l2) is 68 times l1:
l2 = 68 * l1
l2 = 68 * 1/4 yards
l2 = 17 yards
Answer:
5cm
Step-by-step explanation:
To find the missing side we use the hypotenuse theorem.
a^2 + b^2 = c^2
The longest side of the triangle would be c. So substitute the numbers into the variables.
a^2 + 12^2 = 13^2
a^2 = 13^2 - 12^2
a^2 = 169 - 144
a^2= 25
a = √25
a=5
The missing leg's length is 5cm
Answer:
Ok ok, I see. So the answer is -9.
Step-by-step explanation:
We know the expresion is:
-3(-2+5)
We need to distrubute the -3 to what is in the parthese.
When I say distribute, basically you need to multiply the numbers inside the parethese by -3. So we can think of it as:
-3*-2=6
and:
-3*5=-15
Which we can rewrite as:
(6-15)
Subtract 15 from 6 and you get -9:
6-15=-9
Sorry hope this helps!
