A 34-inch piece of wood is 2.4% of a longer piece of wood. How long is the longer piece of wood? Show your work. You can use proportions

Answers

Think of this as a proportion: 2.4 is to 100, as 34 is to L ("L" for "Long piece.")

Cross multiply to get 2.4 L = 3400, then divide both sides by 2.4 to be left with

L = 3400/2.4, so

L = 1416.666...

So the longer piece of wood is 1,416.66... inches long.

The area of the triangle will be equal to 60 square meters. The correct option is B.

What is the area of a triangle?

Triangle is a shape made of three sides in a two-dimensional plane. the sum of the three angles is 180 degrees.

The space occupied by any two-dimensional figure in a plane is called the area. The two-dimensional space occupied by the triangle is called the area of the triangle.

Given that right triangles, MNP and QRS are congruent. Right triangles M N P and Q R S are shown. The length of side Q S is 8 meters. The length of M N is 17 meters and the length of P N is 15 meters.

The area of the triangle is calculated as,

Area = (1/2) x PN x QS

Area = (1/2) x 8 x 15

Area = 4 x 15

Area = 60 square meters

Therefore, the area of the triangle will be equal to 60 square meters. The correct option is B.

A large field measures 70 feet by 25 feet. If the field will be divided into equal square garden plots, what size whoud the largest possible plot be with sides of whole number length?

Answers

Answer:

5 feets

Step-by-step explanation:

Give the field dimension :

70 feets by 25 feets

The largest possible size if field is divided into squares :

Obtain the greatest common factor of the length and width :

Factors of 70 : 1, 2, 5,7,14, 10, 35

Factors of 25 : 1, 5, 25

The greatest common factor = 5

Hence, the largest possible square plot will have a side length of 5 feets

Quadrilateral A B D C is shown. In quadrilateral ABDC, AB ∥ CD. Which additional piece of information is needed to determine that ABDC is a parallelogram? AB ≅ CD AC ≅ BD AB ⊥ BD CD ⊥ BD

Answers

Step-by-step explanation:

For any quadrilateral to be a parallelogram

i) either both the pairs of opposite sides must be equal

ii) Both the pairs of opposite sides must be parallel

iii) Opposite pairs of angles must be equal

iv) Diagonals must bisect each other.

v) A pair of opposite sides must be parallel and equal

Here we are already given that AB || CD

So either we should be given that AD || BC

or we must be given that AB = CD

Here it is given AB = CD as an option.
