3.78 divided by 0.9​

Answers

Answer 1
Answer:

Answer:

4.200

Step-by-step explanation:

Change the divisor 0.9 to a whole number by moving the decimal point 1 places to the right. Then move the decimal point in the dividend the same, 1 places to the right.

We then have the equations:

37.8 ÷ 9 = 4.200

and therefore:

3.78 ÷ 0.9 = 4.200

Both calculated to 3 decimal places.
Answer 2
Answer:

Final answer:

The division of 3.78 by 0.9 equals 4.2 after rounding to the nearest tenth. The given problem is an arithmetic division question typically encountered in mathematics. The keyword 3.78 is the number being divided by 0.9.

Explanation:

The division question posed: 3.78 divided by 0.9, is a simple arithmetic problem. To solve, we will perform the division calculation directly. First, we divide 3.78 (the dividend) by 0.9 (the divisor). This yields a quotient of approximately 4.2. Thus, 3.78 divided by 0.9 equals 4.2 when rounded to the nearest tenth. This division problem would be typically encountered in arithmetic, a branch of mathematics that deals with numbers and numerical computation.

-2p-4=2 please Help me

Answers


                                 -2p - 4 = 2

Add  4  to each side:        -2p = 6

Divide each side by  2 :      -p = 3

Multiply each side by  -1 :    p = -3
To get the answer we have to obtain single p on the LHS.
-2p-4=2      /:-2   (divide both sides by -2)
p+2=-1      /-2    (subtract 2 both sides)
p=-3 - its the answer

Step-by-step explanation:

Some one please help me with this problem. Thank you. NO answers, just explanation on how to solve it.

y = 3/2 t - 5/2 ; where t = 3

Substitute t by its value. the nearness of 3/2 to t denotes multiplication.

y = (3/2 *3) - 5/2

3 is a whole number. it is 3/1 in fraction form. 
In multiplying fractions, simply multiply the numerator and the denominator.

y = (3*3 / 2*1) - 5/2
y = 9/2 - 5/2

Subtracting fractions: We can only subtract or add fractions if they all have the same common denominator. Since both fractions have 2 as denominator, we can proceed to subtracting its numerators.

y = (9-5)/2      *subtract numerators and place over the common denominator
y = 4/2            * simplify the fraction.
y = 2/1 or 2

A company charges $211.25 for 5 trees and 15 shrubs, The company charges$15.25 more for a tree than a shrub. How much does each shrub cost?

Answers

First we make our formula: 5(t+15.25)+15t=211.25. (I use the same letter for both variables, but you have to make sure that whatever makes them different is in the formula) Then you work it like normal: 20t=135, T=6.75 so 1 shrub costs $6.75 Then substitute the answer in: 5(6.75+15.25)+15(6.75)=211.75 and check it. 1 tree is $110 :) hope this helps :)
