Answer:

<h2>1, 3 and 4 are true statements.</h2>

Step-by-step explanation:

Notice that the given triangle has all three side different, that means it's an scalene triangle.

Additionally, the triangular inequality states that the sum of two sides of a triangle must be greater than the third side, that is

DE+EF>DF\\DE+DF>EF\\DF+EF>DE

So, the first choice is also correct.

Then, we use thes triangular inequalities to find the third true statement.

We know that DE=4 and EF=9

DE+EF>DF\\4+9>DF\\DF

Also,

DE+DF>EF\\4+DF>9\\DF>9-4\\DF>5

Therefore, 5, which means side DF must be between 5 and 13.

The third true statement is the third option.

A concession stand charges $2.50 for a bag of popcorn. The stand has already sold 30 bags of popcorn. How many more bags x of po
vesna_86 [32]

Answer:

The concession stands needs to sell 14 or more bags.

Step-by-step explanation:

Given that:

Cost per bag of popcorn = $2.50

Number of bags already sold = 30

Cost of 30 bags = 30*2.50 = $75

Bags needs to be sold to make $110 = x

2.50x + 75 ≥ 110

2.50x ≥ 110-75

2.50x ≥ 35

Dividing both sides by 2.50

\frac{2.50x}{2.50}\geq \frac{35}{2.50}\\x\geq 14

Hence,

The concession stands needs to sell 14 or more bags.

In the number 5.3779, how does the value of 7 in the hundredths place compare to the value of the 7 in the thousandth place?
anygoal [31]

Answer:

  (b)

Step-by-step explanation:

The hundredths place is immediately to the left of the thousandths place. In our base-10 number system, moving a digit to the left one place increases its value by a factor of 10.

The value of 7 in the hundredths place is 10 times the value of 7 in the thousandths place.
