3.9y + 3 - 2.9y=

anybody know?!

Answers

Answer 1

Answer:

= y + 3

Step-by-step explanation:

Group:

= 3.9y - 2.9y + 3

Add elements together:

= y + 3

Answer 2
3.9y + 3 - 2.9y

Arrange equation so that like terms are next to each other

3.9y - 2.9y + 3

Subtract.

1y + 3

Since 1y and 3 are not like terms, we cannot add them.

Therefore, 1y + 3 is the answer.
You can also write y +3.

The electricity consumption in a start-up company was 4 kwh per day. As the manpower increased, the consumption of electricity increased to 10 kwh per day. What is the percent of increase in the consumption of electricity at the start-up company?

Answers

Answer:

150%

Step-by-step explanation:

10-4 is 6, and that is how much it increased by. Now, you have to find what percentage is 6 out of 4. 6/4 is 1.5, so you would multiply 1.5 by 100 to make it into a percent. 1.5*100=150, so your answer is 150%.

So, if I have 30 slides to do, and seven days to do them, how many slides will I do each day?

Answers

Answer: Roughly 4.3 (You would want to do 5 a day, which will make you not need to work the seventh day, if the answer is even.)

Step-by-step explanation:

30 (slides) divided by 7 (days) = 4.28571... = round up to 4.3 or 5

30 divided by 7 is about 4.29 so I would do about 5 slides a day with some days you do 4 slides

Figure ABCD is shown on the coordinate plane. Suppose a graphic designer wants to dilate the figure so that the resulting image has a smaller area than figure ABCD. Describe a way the designer can achieve this type of dilation.

Answers

Answer:

Step-by-step explanation:

If the dilated image is smaller than the original, then 0<k<1.

Meaning the scale factor is less than one, but greater than zero.

You would mulitply each coordinate by this scale factor - to obtain the coordinates of the dilated figure.

Let's choose   [tex]\frac{1}2}[/tex].

In the original figure Point A = (-4,3) dilating by [tex]\frac{1}{2}[/tex] results in A' being (-2, 1.5).  When you multiply each cooordinate (-4,3) by one half.

Applying the scale factor of one half to the other coordinates - yields these results.

Point B (4,3) becomes Point B' (2, 1.5)

Point C (-4,-4) becomes Point C' (-2,-2).

Point D (4, -4) becomes Point D' (2,-2)

Answers

Answer:

On Monday, Marco practiced the piano for 7/10 hour. On Tuesday he practiced for 11/6 hour. To find out how many hours he practiced in total for these two days, we need to add these two amounts together.

We can add these two amounts together by converting them to a common denominator, in this case 24:

7/10 hour = (7/10) * (24/6) = 724/60 = 72/5 = 14/5 hour

11/6 hour = (11/6) * (24/6) = 114/6 = 112/3 = 22/3 hour

So the total number of hours he practiced for these two days is (14/5) + (22/3) = (14+44)/(5*3) = 58/15 hour

He is supposed to practice 5/4 hours each day. To find out how many hours he is still supposed to practice, we have to subtract the total number of hours he practiced from the total number of hours he is supposed to practice per day:

5/4 hour - 58/15 hour = (53)/(43) - (58/15) = 15/12 - 58/15 = (180-58) / (12*15) = 122/180 hour or 0.67 hour

So Marco is supposed to practice 0.67 hour more to meet his daily practice goal.


However I was not able to read what you wrote please check from here. Thanks.
