Answer:

The correct option is A.

Step-by-step explanation:

Braxton is testing 2 different types of motor oil in his truck to determine which one will last longer.

Now, he adds Brand A to the truck and Brand B to his sister's car.

Now, as Braxton wants to test the motor oil in his truck so there is no need of adding the motor oil to his sister's car as by doing so he cannot result in to a meaningful conclusion.

So, Braxton need to add both the motor oil into his truck one by one.

Hence, The conclusion of Braxton is not valid because he added Brand B to his sister's car, not the truck.

Therefore, The correct option is A.

In △ABC, point P∈ AC with AP:PC=1:3, point Q∈AB so that AQ:QB=3:4, Find the ratios APBQ : APBC and AAQP : AABC.
weqwewe [10]

Answer: The  ratios APBQ : APBC=4:21 and AAQP : AABC= 3:28

Explanation:

Here, ABC is a triangle where, P and Q are the midpoints of the edges AC and AB respectively,

Now, according to the question ,AP:PC=1:3 let AP=x and PC=3x where x is any real number. Thus, AC=AP+AC= x+3x= 4x

Similarly,  AQ:QB=3:4 let AQ=3y and QB=4y where y is also any real number. Thus, AB=AQ+QB=3y+4y=7y

Since, \frac{AP.BQ}{AP.BC} =\frac{AP.BQ}{AB.PC} =\frac{x.4y}{7y.3x} =\frac{4xy}{21xy} =\frac{4}{21}

And, \frac{AA.QP}{AA.BC} =\frac{AQ.AP}{AB.AC} =\frac{3y.1x}{7y.4x} =\frac{3xy}{28xy} =\frac{3}{28}

Mary owned n sheep and Sam had exactly 4 times as many sheep as Mary.
Veseljchak [2.6K]

Answer:

The least value of n is, 9.

Step-by-step explanation:

Mary(M) owned the number of sheep is n i.e, M = n sheep

Sam(S) had exactly four times as many sheep as Mary , i.e, S = 4 n sheep

As per the given condition Mary buys 17 extra sheep

Now, Mary has total number of sheep, M = n +17 sheep

And Sam sells 8 of his sheep that means he has now,

But, Sam still has more sheep than Mary i.e,  

Solve an inequality:

Add 8 both sides we get;

Simplify:

Now, subtract n from both the side, we get;

Simplify:

or

Since n is the number of sheep in integer,

then the least value of n is, 9.

Given:<br> Triangle WXY, 1 an exterior .<br><br> Prove:<br> 1 &gt; 2
Oksana_A [137]

Answer:

<h3><1 = <2+< 3.</h3>

Step-by-step explanation:

Given triangle WXY and <1 is an exterior angle.

We need to prove <1 is greater than <2.


First statement is:

Triangle WXY and <1 is an exterior angle.

Reason : Given


<em>Note: An exterior angle of a triangle is the sum of two angles side the triangle those don't makes the linear pair with exterior angle.</em>


We can see that <2 and < 3 are the angles of triangle those are not making a linear pair.


Therefore, <1 = <2+< 3.

So, the second statement should be first option <1 = <2+< 3.
