RATHER THAN USE DECIMALS-convert it to cents..

Mathematics
1 answer:
stepan [7]3 years ago
5 0

Answer:

<h2>there are 22 dimes</h2><h2>there are 44 nickles</h2><h2 />

Step-by-step explanation:

D be dimes and N be nickles

2 nickles as dime

nickle = 5 cents and dime =10 cents

N=2D

0.10 D + 0.05 (N)=4.4 substitute N=2D

0.10 D +0.05(2D)=4.4

0.10D+0.10D=4.4

0.20 D=4.4

D=4.4/0.2 = 22

<h2>there are 22 dimes</h2>

N=2D

N=2(22)

N=44

<h2>there are 44 nickles</h2>

check : 0.10(22)+0.05(44)= 4.4 (correct)

If lateral surface area of cube is double then the ratio of volume of new cube to original cube ​
Solnce55 [7]

Answer:

  2√2

Step-by-step explanation:

The area ratio is the square of the side length ratio, so the ratio of side lengths is √2.

The volume ratio is the cube of the side length ratio, so the new cube has a volume that is (√2)³ times that of the original.

The volume ratio is 2√2.

Solve the inequality. Graph the solution set, and write it using interval notation. |5x+4|less than or equal to 10
aniked [119]

we have the inequality

\lvert5x+4\rvert\leq10

step 1

Find out the first solution (positive case)

\begin{gathered} +(5x+4)\leq10 \\ 5x\leq10-4 \\ 5x\leq6 \\ x\leq\frac{6}{5} \\ x\leq1.20 \end{gathered}

The first solution is all real numbers less than or equal to 1.20

Interval (-infinite,1.20]

step 2

Find out the second solution (negative case)

-(5x+4)\leq10

Multiply by -1 both sides

\begin{gathered} (5x+4)\ge-10 \\ 5x\ge-10-4 \\ 5x\ge-14 \\ x\ge-\frac{14}{5} \\ x\ge-2.8 \end{gathered}

The second solution is all real numbers greater than or equal to -2.8

the interval [-2.8, infinite)

step 3

Find out the solution to the given inequality

The solution is

[-2.8, infinite) ∩ (-infinite,1.20]=[-2.8,1.20]

the solution is the interval [-2.8,1.20]
