Answer:

3 & 4

Step-by-step explanation:

Descriptive investigations are not repeatable because they are based only on observations made at a single point in time. The results may vary at a different time. In addition, descriptive investigations do not contain variables that may indicate cause-and-effect relationships.

Answer: A good scientific question has certain characteristics. It should have some answers (real answers), should be testable (i.e. can be tested by someone through an experiment or measurements), leads to a hypothesis that is falsifiable (means it should generate a hypothesis that can be shown to fail).

Answer:

m<B = 141 degrees

Step-by-step explanation:

This shape is a heptagon meaning its angles should have a sum of 900 degrees.

we are given the degrees and we need to ad them up

148+90+120+129+130+142=749

then we subtract 749 from 900 which looks like

900-749=141

from subtracting 749 from 900 we get 141 hence we get our answer that m<B = 141 degrees

Speed test cost $5 each and large one-topping pizzas cost $6 each write an equation that represents the total cost t of c large

yKpoI14uk [10]

Answer:

Equation t = 5c + 6d represents total cost t of c large pizzas and d large one-topping pizzas

Solution:

Given that

Cost of large pizza = $5 each

Cost of large one-topping pizza = $6 each

Need to write the equation that represents total cost t of c large pizzas and d large one topping pizzas.

From given information

Cost of 1 large pizza = 5

So cost of c large pizzas = c x 5 = 5c

Cost of 1 large one-topping pizza = 6

So cost of d large one-topping pizzas =d x 6 = 6d

Total cost t = cost of c large pizzas + cost of d large one-topping pizzas

=> t = 5c + 6d

Hence equation t = 5c + 6d represents total cost t of c large pizzas and d large one-topping pizzas.

Since we know the side length of the square (6), we can calculate its diagonal using pythagoras.

diag d = √(6²+6²) = 6√2 in

The diagonal is also the diameter of the circle! So the radius of the circle is half of that:

radius r = d/2 = 3√2 in

The area of the circle is πr² = π(3√2)² = 18π in²
