Mathematics

7 0

Answer:

AC=25\ units

Step-by-step explanation:

we know that

An isosceles triangle has two equal sides and two equal interior angles

In this problem

The triangle ABC is an isosceles triangle, because

m∠A=m∠C

therefore

AB=BC

substitute the given values

5x+5=7x-1

solve for x

7x-5x=5+1

2x=6

x=3

<em>Find  the length of side AC</em>

AC=6x+7

substitute the value of x

AC=6(3)+7

AC=25\ units

Terri played 70 tournament chess games during the school year and won 49 of them. What is her win-to-loss ratio?
Scilla [17]

Alright so the answer would be letter B, because

win-to-loss

49 to 21 (You can determine her losses by subtracted the number of wins from her total number of games played)

Now you must simplify your answer

7 is the greatest common factor (GCF) of both 49 and 21

Now divide both 49 and 21 by 7 to get

7 to 3

Look at this set of 5 numbers: 21471 By how much would the mode decrease if the number 1 were added to the set?
Fofino [41]

Answer:

  • Zero

Step-by-step explanation:

The mode is the number of most repeated data in the set.

Given set 2, 1, 4, 7, 1 has mode 1 (repeated twice).

If we add 1 to the set the mode will remain 1 as it will repeat three times, so the mode won't change.

There is no change in mode, so the mode decrease is zero.
