Prove That Quadrilateral ABCD Is A Rhombus Show All The Work

Answers

Answer 1

Answer:

Say that the shape is a parallelogram with equal length sides;

AB = CD

ABD = CDB as the bisecting lines (you have drawn) prove ABD : CDB are both isosceles triangles.

Therefore ABD = ADB

Draw the shape's diagonals as each others' perpendicular bisectors;  

Draw the shape's diagonals bisect both pairs of opposite angles.

If two non congruent angles were given in example 70 degree and 110 degree then say M ∴ = (1/2 )(M∴BAD) = 35  =  (1/2 )(M∴BEF) = 35

and do the same for  1/2(M∴ABC) = 55 = 1/2 (M∴CDA) = 55

9 = 4 + 5

18 = 9×2

23 = 18 + 5

46 = 23×2

If the simple interest on $7,000 for 2 years is 980, then what is the interest rate?

Answers

Answer:

7%

Step-by-step explanation:

since the formula says si=ptr/100

so we have to separate r which gives us r =(i ×100)/(p×t)

now putting the values (980×100)/(7000×2)

=7

therefore the rate of interest is 7%

Step-by-step explanation:

The ratio of yard to feet, is 1 yard to 3 feet

The cafeteria serves pizza every 10 days and corn every 4 days. If they are serving pizza and corn today, in how many days will they serve them together again?

Answers

Answer:

Well it would be 100 days

Step-by-step explanation:

Because they had pizza every ten days and if you add 5 days a week that's 50 days they sell pizza. If your talking corn they sell it every 4 days times 5 days a week that's 20 days of corn. Then you do 50 x 20 and then you get 100 days of pizza and corn, so it would be 100 days before they sell pizza and corn together again!

$4 for 1/4 of a pie, means that it isn't an entire pie. Luckily for us, this is simple multiplication. You would multiply like so:

reduction mean less then 100​

Answers

Answer:

well yes that technically is correct.

Reduction means the action or fact of making something smaller or less in amount, degree, or size

In mathematics, reduction refers to the rewriting of an expression into a simpler form. For example, the process of rewriting a fraction into one with the smallest whole-number denominator possible (while keeping the numerator a whole number) is called "reducing a fraction".

Step-by-step explanation:

An increase of 100% in a quantity means that the final amount is 200% of the initial amount (100% of initial + 100% of increase = 200% of initial). In other words, the quantity has doubled. ... A decrease of 100% means the final amount is zero (100% – 100% = 0%).

Step-by-step explanation:

So what i did is times 5 by 3 to get 15 right?

And then you have 3 days left over so to find out how much it costs per day i divided 6.26 by 5 days and got 1.25

so i times 1.25 by the extra 3 days

which you get 3.25

and with the other 15 days you just times 6.25 by 3 because we already know every 5 days is 6.25 if this makes sense to you
