Answer:

The answer is A. 0.1x + 18.2

Step-by-step explanation:

We have to simplify the expression

We will use distributive Property of Multiplication with respect to Addition and Subtraction

⇒3×(2.7 x +5) -2 ×(4 x -1.6)

=3×2.7 x +3×5-2×4 x-2×(-1.6)

=8.1 x +15 -8 x+3.2

=(8.1 x- 8 x)+15+3.2-----Adding and Subtracting like terms

= 0.1  x +18.2

Option A

The measure of an angle is 28 degrees greater than its complement find the measure of each angle
julia-pushkina [17]

small angle =x

x+(x+28)=90

2x=62

x=31   

90-31= 59

Angles measure     31 and 59

31+59=90

59-31=28

Which of the following are remote interior angles of <1? Check all that apply.
Leto [7]

Answer:

D. \angle 4

F. \angle 6  

Step-by-step explanation:

We have been given an image of a triangle and we are asked to choose the remote interior angles of angle 1.

Since we know that remote interior angles are the two angles that are inside the triangle and opposite from the exterior angle.

We can see that angle 1 is exterior angle of our triangle and and angle 4 an 6 are opposite interior angles of angle 1.

Therefore, angle 4 and angle 6 will be remote interior angles of angle 1 and options D and F are correct choices.

You measure two quantities as A=1.0m±0.2m, B=2.0m±0.2m. We should report correct value for

AB

as

Medium

Solution

Verified by Toppr

Correct option is

D

1.4m±0.2m

Here, A=1.0m±0.2m, B=2.0m±0.2m

AB=(1.0m)(2.0m)=2.0m

AB

=

2.0m

=1.414m

Rounding off to two significant figures, we get
