Hii :D I’m pretty sure it’s D because the equation can be rewritten in standard form or implicit form

Have a great day! I’m so sorry if I’m wrong

A truck stopped at a weigh station along the highway. The sign read "Maximum weight 40.3" the truck weighed in at 40.09 tons. Is

No, the truck is not greater than the maximum weight. If you were to round the truck's weight, it would be 40.1 which is still less than 40.3

Hope this helps! :)

What is the difference in finding the length of a segment that is drawn on a sheet of blank paper and segment that is drawn on a

klio [65]

If you have tickmarks on the segment, on a blank piece of paper, then you count out the spaces to get the length of the segment. This is assuming the tickmarks are properly spaced out. If there aren't any tickmarks, then you'll have to use a ruler to find the length. Either way, a ruler is encouraged.

The coordinate plane makes things easier to find the length of any segment. Use either the pythagorean theorem or the distance formula to find the length of the segment.

a cabinet maker used 0.75 gallons of varnish on 10 cabinet doors. At this rate, how many quarts of varnish are required for 25 c

notsponge [240]

Answer:

1.874quartz

Step-by-step explanation:

Since,0.75 gallon=10cabinet

X gallon=25 cabinet

Cross multiply

10x=0.75×25

10x=18.75

Let's make x the subject of formula by dividing both sides by 10

X=1.875

So 10 cabinet=1.875quarts

Sin97°cos43°+cos97°sin43°

kirza4 [7]

I added a screenshot with the head of the question

Answer:
sin (140°)

Explanation:
Angle addition formulas are used to express the trigonometric function in terms of the sum/difference between two angles α and β
These rules are shown in the attached image.

Now, the given expression is::
sin97°cos43°+cos97°sin43°We have:
α = 97°
β = 43°

Comparing the given formula with the general formulas in the image, we would find that the given formula represents the sum of the sin of two angles.

Therefore:
sin97°cos43°+cos97°sin43°
= sin (97°+43°)
= sin (140°)

Hope this helps :)
