Jerry bought 4 dvds for 25. What was the unit rate ?

We need the normal form first

[tex]\\ \rm\bull\rightarrowtail \dfrac{x}{a}+\dfrac{y}{b}=1[/tex]

[tex]\\ \rm\bull\rightarrowtail \dfrac{x}{3}-\dfrac{y}{2}=1[/tex]

Multiply by 6to bring standard form

Answer:

vertical : horizontal = 1 : 2

Explanation:

UT, vertical length: 3 units

ST, horizontal length: 6 units

Therefore vertical length : horizontal length = 3 : 6 = 1 : 2

Answer:

1:2

Step-by-step explanation:

Triangle PQR has a vertical side of 1 and a horizontal side of 2.

so the ratio is vertical : horizontal is 1:2

Triangle STU has a vertical side of 3 and a horizontal side of 6.

so the ratio is vertical : horizontal is 3:6

which can be reduced by dividing both sides by 3

so the ratio is vertical : horizontal is 1:2

Answer:

A number that is at least 90 is 91.

Step-by-step explanation:

Given :

To Find :

Solution :

We know that,

[tex]\qquad{ \bold{ \pmb{2(Length + Width) = Perimeter}}}[/tex]

So,

Now, Substituting the given values in the formula :

[tex] \qquad \dashrightarrow{ \sf{2[x + (x-4)] = 32}}[/tex]

[tex]\qquad \dashrightarrow{ \sf{2(x + x-4) = 32}}[/tex]

[tex]\qquad \dashrightarrow{ \sf{2(2x-4) = 32}}[/tex]

[tex]\qquad \dashrightarrow{ \sf{4x-8= 32}}[/tex]

[tex]\qquad \dashrightarrow{ \sf{4x= 32 + 8}}[/tex]

[tex]\qquad \dashrightarrow{ \sf{4x= 40}}[/tex]

[tex]\qquad \dashrightarrow{ \sf{x= \dfrac{40}{4} }}[/tex]

[tex]\qquad \dashrightarrow{\pmb{ \bf{x= {10} }}}[/tex]

Therefore,

The median is: 3

Answer:

Original #: 950

New #: 1,520

If it is percent of increase, you would do new amount - original amount over original amount.

1,520 - 950 / 950 = 570 / 950

0.6 or 60%

Answer:

5

Step-by-step explanation:

So let's start with making an equation,

125 x A = 625         Note: A is just a variable for the missing number

125A / 125 = 625 / A

A = 5

So, the missing number is 5

Answer:

5,000

Step-by-step explanation:

Because 5 is in the thousands place and it is asking his neighbor 0 for help and since 0 is it a 5 or above he can't help 5 so 5 has to stay at 5,000 and can't go to 6.

Answer:

Step-by-step explanation:

The store which has the lower total price is B, lower by $1040.

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

Given;

Store B sells the same computer as in the Example for $1,300.

Store B offers a 20% discount on the computer.

Now

Store B offers a 20% discount on the computer,

CB= CA-0.2CA

CB=1300-0.2-1300

CB= 1300-260

CB=1040

Therefore, the cost by 20 percent will be $1040.

Answer:

0.365 kg

Step-by-step explanation:

I hope this explains it and helps :)

Answer:Answer:

0.365 kg

Step-by-step explanation:

The first I did was turn the 250mg to grams so the conversion factor would be 1 milligram = 0.0001 gram.

Divide the 250mg by 1000g to get 0.25g.

Multiply 0.25g by 60 to get 15g.

Add 15g to the weight of the empty basket, 350g. You should end up with 365g.

The question asked for kilograms so divide 365g by 1000.

The final answer is 0.365kg.

I hope this explains it and helps :)
