“To find 623, I can just take the value of 613 then either multiply it by 12 or divide it by 2.” Do you agree with her? Explain why or why not.
Step-by-step explanation:
613 and 623 are very close values.
multiplying by 12 or a division by 2 changes the starting value drastically.
so, this cannot be right.
and dividing 613 by 2 also makes it even smaller. but to get 623 we need to make it bigger.
so, therefore, even without actually calculating the numbers, the statement is proven false.

A triangle has sides with lengths of 17 inches, 20 inches, and 28 inches. Is it a right triangle?
Answer:
no
Step-by-step explanation:
Pythagoras theorem
a2 + b2 = c2
the hypotenuse side is always the longest so its 28
:
[tex]17 { }^{2} + 20 ^{2} = 28 ^{2} [/tex]
289+ 400 =784
689 = 784
so the triangle is not a right angled triangle

The waves will cover a circular area of 7542.96 miles.
What is the area of the circle?The circle is defined as the locus of the point traces around a fixed point called the center and is equidistant from the outer trace. The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the circle in a two-dimensional plane is called the area of the circle.
Given that a radio station sends out radio waves in all directions from a tower at the center of the circle of broadcast range. The circle has a diameter of 98 miles.
The area of a circle is calculated by the formula below:-
Area = ( π / 4 ) d²
Area = ( π / 4 ) ( 98 )²
Area = 7542.96 square miles
Therefore, the waves will cover a circular area of 7542.96 miles.

. Imagine you are a restaurant owner. You are trying to set the menu price for the seared scallops with rice and mango salsa. Your item food cost is $6.78 and you set your food cost percentage to 33%. What would you set the price to be on the menu? *
1 point
$16
$18
$20
$21
The price of the food on the menu will be set at $21.
Cost of food item = $6.78
Food cost percentage = 33%
Let the price on the menu be represented by x.
Therefore, based on the information given, the equation to solve the question will be:
= 33% × x = $6.78
33/100 × x = $6.78
0.33 × x = $6.78
0.33x = $6.78
x = $6.78/0.33
x = $20.54
x = $21 approximately
Therefore, the price of the food on the menu will be set at $21.
