|x−y+z|, if x=3; y=−2; z=−6

Mathematics

1 answer:

Finger [1]3 years ago

3 0

Answer:

Step-by-step explanation:

Try the question without the absolute value brackets first.

Then it would be 3+2-6

Since it states "x-y" and y is -2, then it would be 3+2 since a negative times a negative becomes a positive

Same thing for "z", instead of +6 it would be -6 because a negative times a positive is still a negative

Now, 3+2-6 is -1 but MAKE SURE to put the absolute value brackets back. Making the answer a positive number. Therefore, it would be 1

ernie thinks he is being stalked by his own shadow. if the ratio of ernie's height to his shadow's height is 1.5 to 1, and ernie

Anna71 [15]

The height of Ernies shadow is 4 feet when his height is 6 feet.

<h3>equation</h3>

An equation is an expression used to show the relationship between two or more variables and numbers.

Let x represent the length of his shadow. Given that the ratio of ernie's height to his shadow's height is 1.5 to 1. Hence:

(1.5/2.5) * y = 6
y = 10 feet

(1/2.5) * 10 = x

x = 4 feet

The height of Ernies shadow is 4 feet when his height is 6 feet.

Juan's living room floor is shaped as shown. He wants to buy a rug the covers at least half of the floor area. Answer yes or no

slega [8]

Answer:

Step-by-step explanation:

Find the area of the shape by creating two shapes. A large rectangle and a very small triangle. The area of the rectangle is 13x12, and the area of the triangle is (1/2)3x4. The area of both shapes together is 6+156=<u>162</u>.

Now you can easily calculate the area of each rug and determine whether it is over half of 162 (because 162 is the area of the entire floor), or under half of 162. If it is under 81, then it does not cover at least half of the floor.

12x6 = 72 no

10x9 =90 yes

13x12 = 156 yes

3x12 = 36 no

8x8 = 64 no

Please somebody help me

Sholpan [36]

Answer:

Corresponding: 1 and 5, 2 and 6, 3 and 7, 4 and 8

Alternate Exterior Angles: 1 and 8, 2 and 7

Alternate Interior Angles: 3 and 6, 4 and 5

Step-by-step explanation:

Searching up the definitions could really help you understand what kinds of angles there are.

Alternate Interior Angles are a pair of angles on the inner side of each of those two lines but on opposite sides of the transversal.

Alternate exterior angles are defined as two exterior angles on opposite sides of a transversal which lie on different parallel lines.

The corresponding angles are the ones at the same location at each intersection.
