Answer:
pizzeria1
Step-by-step explanation:
Given data
pizzeria1
Diameter=16in
Radius= 16/2= 8in
Area= πr^2
Area= 3.132*8^2
Area= 201.09 in^2
pizzeria2
Diameter=15in
Radius= 15/2= 7.5in
Area= πr^2
Area= 3.132*7.5^2
Area= 176.74n^2
Answer:
There would be $ 0.99 sales tax on the meal.
Step-by-step explanation:
Given,
The cost of the meal ordered by him = $15,
sales tax rate percentage = 6.6%,
Thus, the amount of the sales tax = 6.6% of the cost of the meal
= 6.6% of 15
The total number of students in the four classes is 100 students.
<h3>How to compute the value?</h3>
From the information, the numbers of students in the four sixth-grade classes at Northside School are 26, 19, 34, and 21.
Therefore, the total number of students will be:
= 26 + 19 + 34 + 21
= 100
Therefore there are 100 students.

Answer:
Step-by-step explanation:
This is a question that uses the Pythagorean Theorem.
a = 35 feet
b = x which is the height of the tree.
c = 3*x + 1 so we are trying to find x. Substitute into a b and c
a^2 + b^2 = c^2
35^2 + x^2 = (3x + 1)^2
35^2 + x^2 = 9x^2 + 6x + 1 Subtract x^2 from both sides.
35^2 = 8x^2 + 6x + 1 Subtract 35^2 from both sides.
0 = 8x^2 + 6x + 1 - 35^2
0 = 8x^2 + 6x - 1224
Does this factor?
(x + 12.75)(x - 12)
x - 12 = 0 is the only value that works.
x = 12
The tree is 12 feet high.
Note: I used the quadratic formula to solve this.
