Pleasssee helppp I’m gonna going to fail ):

stich3 [128]

Answer:

The value of a and b is given. All u hv to do is just place the values in the places of a and b. The value of a= 3.1 and b= 7.3.

5i) a+b

3.1+7.3

=10.4

ii) b-a

7.3-3.1

=4.2

5 and 6 are both similar. Just place the numbers instead of the letters

6i) x+y

5+7

=12

ii) y-x

7-5

=2

iii) x/y

5/7

=0.714

There u go :D

Nick has to build a brick wall. Each row of the wall requires 62 bricks. There are 10 rows in the wall. How many bricks will Nic

Alja [10]

We know that each row would require 62 bricks, and considering that the wall will have multiple rows, we will be multiplying 62 by the number of rows. Since the wall has 10 rows, Nick has to use the 62 bricks 10 times (since 1 row requires 62 bricks, he would have to build that 1 row 10 times.)

If we think about the operation of multiplication, we can write “62 ten times” as 62 x 10 (or, when calculated, 620 bricks).

A teacher dropped 8 coins on the table and counted the number of tails to simulate the number of questions a student might guess

Tomtit [17]

Answer:

Get 0 tails (correct answers in the test)

Get 5 tails (correct answers in the test)

Step-by-step explanation:

This is a problem of empirical probability calculation, since the teacher tries to find by means of the experimental method, the number of correct answers that a student could correctly guess in a true / false test with 8 questions.

If the teacher throws the 8 coins and then counts the number of tails, the graph shows the frequency with which 1, 2, 3, 4, 5, 6, 7 and 8 tails are obtained in the 100 attempts.

Therefore, the least probable result was the one that was obtained less frequently in the experiment or, in other words, the one that contains fewer points in the diagram, which in this case are:

Get 0 tails (correct answers in the test)

Get 5 tails (correct answers in the test)

I need help with this question, if anyone could help ASAP, that would be much appreciated. In the figure below, mROP = 125° Find

Tema [17]

Answer:The measure of the arc RPQ is 205°

Step-by-step explanation:

Given the figure in which

m∠ROP=125°

we have to find the measure of the arc RPQ.

As QP is diameter i.e a straight line therefore

∠1 and ∠2 forms a linear pair hence these angles are supplementary.

By supplementary law

∠1+∠2=180°

∠1+125°=180°

∠1=180°-125°=55°

Now we have to find the measure of the arc RPQ i.e

we have to find the measure of ∠2+∠3

By theorem, angles around a point will always add up to 360 degrees.

∴ ∠1+∠2+∠3=360°

55°+∠2+∠3=360°

∠2+∠3=860-55=205°

Hence, the measure of the arc RPQ is 205°
