Explain how the sum will be greater than 5 <br> 3 3/4 + 1 1/2=

aivan3 [116]

This is because 3 3/4 (3.75) + 1 1/2 (1.50) is 5.25. So first you can find the common denominator for 3/4 and 1/2. The xommon denominator is 4 since 3/4 already have a common denominator of 4 you leave 3 34 alone. For 1/2 multiply the nuerator and denominator by 2 resulting in 2/4 so together its 1 2/4. When you add 3 3/4+ 1 2/4, you will get 5 1/4 or 5.25. The easier way is just converting the fractions to decimal. Therefore the answer is 5.25. 5.25> 5

Which pair of triangles can be proven congruent by using the HL theorem?

kaheart [24]

Answer: figure C.

Explanation:

The HL theorem is the hypotenuse leg theorem.

The HL theorem is referred to the congruency of right triangles.

This theorem states that two right triangles that have a congruent hypotenuse and a corresponding, congruent leg are congruent triangles.

Figure A shows the congruency of two pairs of legs. So, this is not the answer.

Figure B shows the congruency of one pair of legs and one pair of angles. So, this is not the answer.

Figure C. shows the congruency of the two hypotenuses and one pair of legs. So, this is the righ answer.

Rudiy27

A can of paint is a cylinder, so we must use the surface area for a cylinder.
2( $\pi$ r $r^{2}$ ) is the top and bottom.

The surface of the can is a rectangle with a length equal to the circumference of the can.

Faliha runs around a square field of side 70m, while Rameen runs around a rectangular field with length 90m and breadth 60m. Who

inn [45]

$\huge\sf\green{Answer :- }$

<h2>Given :- </h2><h2 />

Side of the square field = 70m

Length of the rectangular field = 90m

Breadth of the rectangular field = 60m

Perimeter of the square field

Perimeter of the rectangular field

<h2>Solution :-</h2>

Perimeter of the square = 4 × side

By substituting values,

⇒ 4 × 70m

➥ 280m

<h3><u>Hence, </u><u>Faliha</u><u> runs 280m around a Square </u><u>field</u></h3>

Perimeter of the rectangle = 2( length + Breadth)

By substituting values,

⇒ 2( 90m + 60m )

⇒ 2( 150m)

➥ 300m

<h3><u>Hence, Rameen runs 300m around a rectangular field</u></h3>

By comparing perimeters, Rameen runs more than Faliha

Distance runs more by rameen = Distance covered by rameen - distance covered by faliha

By substituting values,

⇒ 300m - 280m

➠ 20m

<h3><u>Hence, </u><u>Rameen</u><u> runs more around a rectangular field by 20</u><u>m</u></h3>
