The sharadze family is planning a car trip to atlanta, georgia, which is 279 miles from their home. they plan to drive at an average speed of 62 miles per hour. they also plan to stop for lunch for 45 minutes. based on their plan, when should they leave in order to arrive in atlanta at 3:00 p.m.?

The Sharadaze family should leave at 10:45 am. 

279(miles)/62(miles)=4.5(min.)  4.5(min.)-45(min.)=4.15

10:45+4:15=2:60 which is 3:00

which proves that the Sharadaze family should leave at 10:45 am.

How can you quickly calculate 20 percent of any bill amount?

First, convert the percent into a decimal. To do this, simply more the % sign two places to the left and make it into a decimal point.

20% = 0.20

Then we will let x be our bill amount.

Then multiply 0.20 and x together to get your answer.

So, 0.20 * x is your answer.

ANSWER FAST PLZZZ Which polygons are congruent? Select each correct answer. Two right scalene triangles labeled D E F and P Q R. Corresponding sides and vertices contain one, two, and three tick marks, respectively. Angles E and Q are right angles. Two triangles labeled T U V and W X Y. Side T U is labeled three, side U V is labeled six and five-tenths, and side V T is labeled seven. Side W X is labeled three, side X Y is labeled six and five-tenths, and side Y W is labeled seven. Corresponding vertices contain one, two, and three tick marks, respectively. Two triangles labeled A B C and F G H. Angles A and F are labeled eighty-three degrees. Angle B is labeled forty-eight degrees, angle C is labeled forty-nine degrees, angle G is labeled forty-five degrees, and angle H is labeled fifty-two degrees. Sides B C and G H each contain one tick mark. two right triangles. one with legs 4 and 7 units. the other one with legs 5 and 8 units.

Answer with explanation:

Two Triangles are Congruent by following Geometrical Axioms

1. SAS

2.SSS

3. AAS

4. ASA

1. In Δ DEF and Δ P QR

PQ=DE

∠DEF=∠PQR→→Each being 90°

EF=QR

Δ DEF ≅ Δ P QR→→[SAS Congruency]

2. As in Image 2, only one angle is common

we can't say that triangles are congruent.

3. In ΔT UV and Δ W X Y

WX=TU

UV=XY

TV=WY

∠TUV=∠WXY

∠UTV=∠XWY

ΔT UV ≅ΔW X Y→→[By SAS or AAS or SSS]

4.In ΔABC and ΔFGH

∠A=∠F=83°

we can't say that triangles are congruent,as neither the other two angles nor the other two sides are equal.

5. None of the sides nor of the angles are equal .So the triangles are not congruent.

→→So, Image 1, Image 3,  are congruent Polygons.

QUESTION POSTED AT 29/03/2020 - 04:32 PM

Compute and compare the side lengths of the two figures. Does this support an argument claiming that they are congruent? What else must be true to say two polygons are congruent?

The side lengths of the two figures can be calculated with the distance formula:

 √ (x1 - x2)² + (y1 - y2)²        

AB = √13  

BC = √13      

CD = √13    

DA = √13  

A'B' = √13      

B'C' = √13      

C'D' = √13      

D'A' = √13

They are all the same lengths. This supports an argument claiming that they are congruent because if the sides are congruent, then the two polygons are congruent.

Something else that must be true to say that two polygons are congruent is that the angles have equal measures.

Hope this helps! :)
