What is the product written in scientific notation? (1.4 × 103)(2.5 × 10–6) A. 3.9 × 10–3 B. 3.9 × 10–18 C. 3.5 × 10–3 D. 3.5 × 10–2

Answers

Just multiply as shown below:-

1.4 * 2.5 = 3.5
10^-6 and 10^3 = 10^-6+3 = 10^-3

3.5 * 10^-3

Answer: C. 3.5 × 10–3
Hi

1.4 × 10³ × 2.5 × 10⁻⁶ = 1.4 × 2.5 × 10³ × 10⁻⁶ = 3.5 × 10⁻³

1.4 × 2.5 = 3.5 

10³ × 10⁻⁶ = 10³⁻⁶ = 10⁻³

Answer: C) 3.5 × 10⁻³

140% of what number is 35

Answers

Hello :)

140% of 35 is 25                 
x = 25
We assume, that the number 35 is 100% cause it's the output value of the task, X is the value that we are looking for if 35 is 100% then, we can write it down like thiss ↓

 35= 100%

 we know, that x is 140% of the output value, so we can write it down as↓

x= 140% which leads use to 2 simple equations now

35= 100%
x= 140%

where left side of both of them have the same units so, we can do something likee that ↓

35/x= 100%/140% now we have to solve the equation

35/x= 100/140
(35/x)·x= (100/140)·x
multiply both sides of the equation by x
35= 0.714285714286·x
divide both sides of the equation by
(0.714285714286) to get x
35/0.714285714286= x
which would be

49= x
x= 49

now we are here - 140% of 35= 49, THERE's YOUR ANSWER IK ITS LENGTHY BUT THATS ALL THE STEPS TO HELP U . HAVE GREAT DAY

Triangle KNM is isosceles, where angle N is the vertex.Isosceles triangle K N M is shown. N L is a perpendicular bisector of angle K N M. Angle K N L is (5 x + 10) degrees and angle L N M is (6 x minus 1) degrees.

What is the measure of angle K?
11º
25º
50º
65º

Answers

Answer:

25°

Step-by-step explanation:

In isosceles triangle KNM, NL is a perpendicular bisector of angle KNM.

This means

m\angle KNL=m\angle LNM

Since

m\angle KNL=(5x+10)^(\circ)\n \nm\angle LNM=(6x-1)^(\circ),

you have

5x+10=6x-1\n \n5x-6x=-1-10\n \n-x=-11\n \nx=11

No, find the measure of angles KNL and LNM:

m\angle KNL=(5\cdot 11+10)^(\circ)=65^(\circ)\n \nm\angle LNM=(6\cdot 11-1)^(\circ)=65^(\circ)

and the measure of angle KNM is

m\angle KNM=m\angle KNL+m\angle LNM=65^(\circ)+65^(\circ)=130^(\circ)

Angles adjacent to the base of isosceles triangle are congruent. The sum of the measures of all interior angles is 180°, then

m\angle K=(1)/(2)(180^(\circ)-130^(\circ))=25^(\circ)

Answer:

25 Degrees
