Answer:

The speed of car production increase at 250%

Step-by-step explanation:

we know that

20 cars in a day represent the 100%

so

Using proportion

Find out how much percentage represent the production increase

The production increase is 70-20=50 cars per day

\frac{20}{100\%} =\frac{50}{x}\\\\x=100(50)/20\\\\x=250\%

therefore

The speed of car production increase at 250%

neonofarm [45]

Answer:


Step-by-step explanation:

Given :  universal set in this diagram is the set of integers from 1 to 15.

Solution :

The intersection of odd integer,multiples of 3 and Factors of 15 are 3,15

The intersection of odd integer and Factors of 15 are 1,5

The intersection of odd integer,multiples of 3 is 9

The remaining multiples of 3 are 6,12

The remaining odd integers are 7,11,13

Now the remaining integers are 2,4,8,10,14 and these integers must be placed in the boxes outside the circles Since they does not belong any intersection or odd integer or factor of 15 .

Refer the attached figure for the answer.

Find the complete factorization of the expression. 48x + 56xy A) 8x(6 + 7y) B) 8x(7 + 6y) C) 8xy(6 + 7) D) 8xy(13)
mel-nik [20]
Hello there!

The expression:48x+ 56xy

We know we can't add them together since 56 is being multiplied by y. We aren't going to combine 48x and 56xy. They will remain separate terms. 

We know that "C" and "D" are not the answers. 

However, we can check the following expressions to see if they match the given expression.

8x(6+7y)= 8x*6= 48x  8x*7y= 56xy <=== "A" is correct

"A" is the correct answer. 

I hope this helps!

3(2x+8)=8x+46 answer
MrMuchimi
3(2x+8)=8x+46
6x+24=8x+46
-2x+24=46
-2x=22
x=-11

3(2(-11)+8)=8(-11)+46
3(-22+8)=-88+46
3(-14)=-42
-42=-42

Hope I didn't mess up for your sake

What are the x-intercepts of the graph y=f(x+4)
Sergio [31]
The graph is y=x+4, to get the x-intercept we let y=0; and solve for x
thus we shall have:
0=x+4
subtract 4 from both sides
0-4=x+4-4
-4=x
hence the x-intercept will be at point (-4,0)
