Ian multiplied a number by 5 he then multiplied that product by 2 what digit is in the ones place of the final product

Answers

Answer 1

Answer: IF the original number was an integer, then the digit in the ones place of the final product is a zero ( 0 ). If it wasn't an integer, then any digit can be in the ones place.

Answer 2

Answer: zero!
when you multiply by five, you'll always get a number ending in 0 or 5. multiplying by two means if you get one ending in 5, it gets multiplyed by 2 and equals zero anyways

The figure shows two right trapezoids. Trapezoid A B C D has right angles at B and C. Angle B is adjacent to the shorter parallel side. Angle C is adjacent to the longer parallel side. Angle A is obtuse. Angle D is acute. Sides A B and C D are parallel. The sides in order of length from shortest to longest are B C, A D, A B, and C D. Trapezoid R S P Q has right angles at S and P. Angle S is adjacent to the shorter parallel side. Angle P is adjacent to the longer parallel side. Angle R is obtuse. Angle Q is acute. Sides R S and P Q are parallel. The sides in order of length from shortest to longest are S R, R Q, R S, and P Q.The two figures shown above are congruent. Identify the corresponding sides and angles.

please help this is all they gave me

Answer:

In the trapezoids ABCD and RSPQ,

Angles A, B, C and D are corresponding to the angles R, S, P and Q respectively,

Also, the sides AB, BC, CD and DA are corresponding to the sides RS, SP, PQ and QR respectively.

Since, when two figures are congruent to each other then their corresponding sides and angles are also congruent.

Here, trapezoids ABCD and RSPQ are congruent.

Therefore, AB≅RS, AB≅RS, AB≅RS, AB≅RS

And, ∠A ≅ ∠R, ∠B ≅∠S, ∠C≅∠P, ∠D≅∠Q

The coach can select the captain in 20 ways (i.e. from all the available 20 players), and he can select the co-captain in 19 ways (i.e. after selecting the captain, there will be 19 people left).
Therefore, the coach can select the captain and the co-captain in 20 x 19 = 380 ways.

Answer:

Step-by-step explanation:

1. Number of peoples available to choose from = 20

$\text{Ways of selecting the captain from 20 people = }_(1)^(20)\textrm {C}=20$

After selecting the captain number of people left among which co captain can be selected = 20 - 1 = 19

$\text{Ways of selecting the co captain from 19 people = }_(1)^(19)\textrm {C}=19$

Hence, Number of ways a coach select the captain and co-captain of a team from a group of 20 people = 20 × 19 = 380

Therefore, The correct option is C. 380

2. Total number of players = 7

Number of players to be selected = 5

$\text{So, number of ways of selecting 5 players out of 7 = }_(5)^(7)\textrm {C}=21$

Therefore, The correct option is A. 21

3. Total number of outcomes = 20

The digits 1, 2, 3, 4, 5, 6 represent the student who make a C

Number of students who make a C at least 3 times = 13

$\bf\textbf{Required Probability = }(13)/(20)$

Therefore, The correct option is D

Can someone please check if I’m right please, I have a test tomorrow.

You can substitute “x” For your answer and solve the problem that way ^^

It’s a a way to “check” yourself.

If it doesn’t fit in and you not get the answer shown the x substitute is incorrect.

I personally think they are right! I also have a test on two step/one step equations lol

Janice is trying to earn $30 to buy a necklace. She has saved $5.25. She earns $2.25 per hour weeding her grandmother's garden and she earns $5.50 per hour selling seashells at the flea market. Will Janice have enough to buy the necklace if she works in the garden for 2 hours and at the flea market for 4 hours? Use the inequality 2.25y + 5.50z + 5.25 ≥ 30.
