Coach De Leon purchases sports equipment. Basketballs cost $20.00 each, and soccer balls cost $18.00 each. He had a budget of $150.00.

Answers

Answer:

18s+20b<_150

Step-by-step explanation:

He can buy 5 basketballs and 2 soccer balls. This equation is correct because 18x2 is 36 and 20x5 is 100. So that will be a total of $100. This makes the equation 100<_150. You can infer that this equation is true.

Question 9 of 10
Which of the following tools did the Greeks limit themselves to in their formal
geometric constructions?
Check all that apply.
O A. Straightedge
O B. Compass
C. Ruler
D. Tracing paper

Answers

It should be B because they didn’t have all that stuff at the time and people would just use compass

The tools that Greeks limit themselves to in their formal geometric constructions are straight edge and compass. Therefore, A and B are the correct answers.

What are geometric constructions?

Geometric construction is the process of drawing a geometrical figure using two geometrical instruments, a compass, and a ruler.

Compass and straight edge were the tools that were used by Greeks in their formal geometric construction.

During earlier Greek times, simple geometric tools were used like compass and straight edge to draw something. Rulers and other tools came to use much later in time.

Therefore, A and B are the correct answers.

Bill's rectangular bedroom is 2 m long, 4 m wide, and 2.5 m high. Air typically has around 4,000 bacteria per cubic meter. About how many bacteria are present in Bill's bedroom?

Answers

Answer:

80000bacterias

Step-by-step explanation:

Volume of the bedroom= length ×width× height

Given

Length = 2m

Width = 4m

Height= 2.5m

Volume of the bedroom= 2×4×2.5

Volume of the bedroom = 20m³

Given that;

4000bacterias = 1m³

x bacteria = 20m³

Cross multiply

x =4000×20

x =80000

Hence 80000 bacteria's are present in Bill's room

A. (–4 + i) + 4i = –4 + (i + 4i)

Step-by-step explanation:

edge2020

Have a great day y'all :)

(–4 + i) + 4i = –4 + (i + 4i) is the associative property of addition. Thus, option A is correct.

What is the associative property of addition?

According to the associative property of additionally, whenever at least three figures are added together, the outcome is unaffected by the sequence in which the individual numbers are added.

In the first given condition is is stated:

(–4 + i) + 4i  = –4 + (i + 4i)

-4 + i + 4i = -4 + i + 4i

5i - 4 = 5i - 4

As the LHS = RHS, the property is said to be valid for the associative property of addition.

Therefore, option A is the correct option.
