7.8+3.5w-1.5 for w = 6.8

Answers

Answer 1

Answer: first multiple 3.5 with w which is 6.8, then collect 7.8 with the result (23.8) and finally substrack 1.5.
to make it easier after multiple write the numbers on end.

Answer 2

Answer: This question is so easy.
7.8+(3.5x6.8)-1.5
=7.8+23.8-1.5
=30.1

Could the points (-4,3), (-1,1) and (1,3) form the vertices of a right triangle? Why or why not?

Answers

Answer:

The given points of triangle do not form a right triangle because they are satisfying the property of right angle triangle.

Step-by-step explanation:

Given : The points (-4,3), (-1,1) and (1,3)

To find : Could the points form the vertices of a right triangle? Why or why not?

Solution :

First we find the distance between the points so that we get the length of the sides.

Let, A=(-4,3), B=(-1,1), C=(1,3)

Distance formula is

$d=√((x_1-x_2)^2+(y_1-y_2)^2)$

The distance between point A and B

$|AB|=√((-4+1)^2+(3-1)^2)=√(9+4)=√(13)$

The distance between point B and C

$|BC|=√((-1-1)^2+(1-3)^2)=√(4+4)=√(8)$

The distance between point A and C

$|AC|=√((-4-1)^2+(3-3)^2)=√(25+0)=5$

According to property of triangle,

If the square of larger side of triangle is equating to the sum of square of smaller side $a^2=b^2+c^2$ the triangle is right triangle .

Larger side of the triangle is AC=5 unit and smaller sides are $AB=√(13)$ and $BC=√(8)$

$AC^2=AB^2+BC^2$

$5^2=√(13)^2+√(8)^2$

$25=13+8$

$25\neq21$

So, The given points or the vertices of triangle do not form a right triangle because they are satisfying the property of right angle triangle.

$A=(-4,3),B=(-1,1),C=(1,3)\n |AB|=√((-4+1)^2+(3-1)^2)=√(9+4)=√(13)\n |BC|=√((-1-1)^2+(1-3)^2)=√(4+4)=√(8)\n |AC|=√((-4-1)^2+(3-3)^2)=√(25+0)=5\n L=√(13)^2+√(8)^2=13+8=21\neq5^2\neq\ R$

It's impossible to form right triangle using thes points.

Plsssssss hlp asap!!! Find the mode for the data set.18, 24, 24, 24, 25, 37, 37, 46

A.
14

B.
25

C.

D.
There is no mode

Answers

We find the mode as the value that occurs most often in a set:
18, 24, 24, 24, 25, 37, 37, 46
there are 24 three times, that is the mode

the first one is B because twenty four shows up the most in the data set. the second one is D, there is no mode, because no number shows up more than the other numbers in the data set.

If 80% is 60 marks, what is full marks?

Answers

Well, f 80% is 60 marks, you'll need 20% more to make it full, so it would be 15 more marks, which would be 75 total marks = 100% =)
I hope I helped! =D

if 80% is 60...20% is 15...so x5.....100%=75 is the answer

Estimate the answer to 341÷28

Answers

To estimate this question, you can round the numbers to be compatible, to make it easier for yourself. The numbers should be able to be divided cleanly, as this is an estimate, not the actual problem solving. You could, for example, round 341 to 300, and 28 to 30, and divide them to get 10.
Hope that helped.

If you have to estimate what the answer is it has to be reasonable... any answer is right as long as it is reasonable
