A photo frame in the shape of a quadrilateral has one diagonal longer than the other. Is it a Rectangle? Why

Mathematics
1 answer:
julsineya [31]3 years ago
3 0

Answer:

  • 80°

Step-by-step explanation:

A rectangle has same opposite sides and 4 right angles as property of a rectangle.

The photo frame has different diagonal lengths

It makes opposite sides different, therefore it is not a rectangle

<u>Given angles (x - 20) and (x + 40) are consecutive interior angles which add up to 180°</u>

  • x - 20° + x + 40° = 180°
  • 2x + 20° = 180°
  • 2x = 160°
  • x = 80°

Cheryl is planning a garden that will be
GaryK [48]

Hello There!

Great Question!

To calculate the area of a rectangular prism, you would multiply the length, the width, and the depth. As we want to measure this in cubic feet, we should convert all of the measurements to feet to begin with.

How wide is the garden? (either 7 or 8 feet)

How long is the garden? (Whichever of 7 or 8 wasn’t used)

How deep is this garden? 6 inches.

Well, that’s not feet, right?

How many inches are in a foot? 12.

Divide 6 by 12, what is the answer? .5.

(Will give brainliest) Is my answer correct?? If not please correct me
Yuki888 [10]

Hey!

-------------------------------------------------

Answer:

(-6, 2) and (-7, -1) and (0, 0)

-------------------------------------------------

Explanation:

You reflected the triangle. You needed to translate the triangle.

y + 6 is to move up 6 units along the y-axis.

x - 5 is to move left 5 units along the x-axis.

Another thing, the question doesn't state was transformation to use so we are going to assume we are translating.

-------------------------------------------------

Hope This Helped! Good Luck!

2. Choose the graph that shows the solution of the inequality on the number line
horsena [70]

Answer:

Number line 3 also known as [C]

Step-by-step explanation:

<em>Given that:</em>

<em>c ≤ </em>-1

Knowing that:

≤  = Less than or equal to

Now substitute into the equation:

C less than or equal to -1

Thus, it going left on a number line.

The only number line with left is [A] and [C]

Since ≤  = Less than or equal to -1

then, it including -1

also known as a closed circle means the number is included and an open circle means it is not.

Hence, it closed circle.

Thus, the answer is [C]

Adam is going to cook a turkey for 14 people and wants to allow 3/4 lb of turkey for each person. 1lb = 450g
Zarrin [17]
(You forgot to add the question, but I guess you want to know the mass of the turkey for 14 people :p )
By hypothesis, 1 lb = 450g. Adam wants that each of the 14 person, get 3/4 lb. Let x be the mass of 3/4 lb in grams, using the rule of three:

1 lb --> 450g
3/4 lb --> x

x = 3/4 * 450 = 337.5
So 3/4 lb = 337.5 g

Adam wants to cook for 14 people and wants to allow 3/4 lb of turkey for each person, so 337.5 for each.
So to know the total mass of the turkey, you multiply the mass for one person by the total  number of people:
337.5 * 14 = 4725
So the mass of the turkey for 14 people is 4725g, or 10.5 lb (3/4 * 14)

Hope this Helps! :)
