9514 1404 393

Answer:

9.6 kW

Step-by-step explanation:

The product of volts and amps is watts. Here, that product is ...

(240 V)(40 A) = 9600 W

1000 W is 1 kW, so this quantity is 9.6 kW

This tells the power consumption. The "rating" may be different.

Find the value of x.

Mrac [35]

Answer:

Step-by-step explanation:

subtract each external angle by 180 to find the interior angle.

Since you know that all of the interior angles add up to 540 because 180(n-2)

with n is how many sides in the polygon

so 180(5-2)=540

now take each value and subtract it by 180

180-(45)=135

180-(40)=140

180-(x)=180-x

180-(77)=103

180-(2x)=180-2x

135+140+180-x+103+180-2x=540

738-3x=540

x=66

hope that helps :)

4) Circle which statement(s) are TRUE:<br> 4a. 3 x 42 = 3 x 16<br> 4b. 35 = 53<br> 4c. 25 = 10

Ganezh [65]

A = false, it is simply not possible
B = false, it is also not possible
C = false, so it is also impossible

Am I missing anything? If not, I guess just don’t circle any of them!

Which of the following best describes the graph above?

natta225 [31]

Answer:

Step-by-step explanation:

A relation between two sets is a collection of ordered pairs containing one object from each set. If the object x is from the first set and the object y is from the second set, then the objects are said to be related if the ordered pair (x,y) is in the relation.

A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

The graph represents the relation, but not a function.

This is relation, because it defines the rule for each $x\in [-4, 3]$ some $y\in [-1, 5]$ such, that the ordered pair (x,y) lies on the graph.

This is not a function, because for all input values of x (excluding x=3) we can find two different output values of y.
