Answer:

0.4

Step-by-step explanation:

-1/5 = -2/10 = -0.2, -1/4 = -25/100 = -0.25

-0.25-(-1/5)+0.2+(-1/4) = -0.25+0.2+0.2+0.25 = -0.25+0.25+0.2+0.2 = 0.4

Identify the reflection of the figure with vertices P(−11,−13), Q(−17,19), and R(23,−27) across the x-axis.
Bess [88]

Answer:

P (−11, 13), Q (−17, −19), R (23, 27)

Step-by-step explanation:

we know that

The reflection of a figure across the x-axis has the following rule

(x,y) -----> (x,-y)

so

P(-11,-13) -----> P(-11,13)

Q(-17,19) -----> Q(-17,-19)

R(23,-27) ----> R(23,27)

URGENT!! A student needs 3 pieces of wire for a science project. The second piece must be 3 times as long as the first. The thir
Marianna [84]

Answer:

Part a) The inequality that represent the situation is

x+(3x)+(6x) \leq 350\ in  

Part b) The possible lengths of the shortest piece of wire are all positive real numbers less than or equal to 35\ inches

Step-by-step explanation:

Let

x------> the length of the first wire

3x---> the length of the second wire

2(3x)=6x -----> the length of the third wire

Part a) WRITE AN *INEQUALITY* THAT MODELS THE SITUATION

we know that

The inequality that represent the situation is

x+(3x)+(6x) \leq 350

Part b) WHAT ARE THE POSSIBLE LENGTHS OF THE SHORTEST PIECE OF WIRE?

we know that

The shortest piece of wire is the first wire

so

Solve the inequality

x+(3x)+(6x) \leq 350

10x \leq 350

x \leq 35\ in

The possible lengths of the shortest piece of wire are all positive real numbers less than or equal to 35\ inches
