Find the smallest number which is exactly divisible
by 15 20 and 30
​

Answer:

60 liters of 20% solution & 20 liters of 60% solution

Step-by-step explanation:

80*0.3=.2x+0.6(80-x)

24=0.2x+48-0.6x

-24=0.2x-0.6x

-24=0.4x

24=0.4x

60=x

Hope this helps!! This is step by step btw!

Step-by-step explanation:

(4 , - 4) -----> ( 4 - 4 + 4 , - 4 ) = ( 4 , - 4 )

Answer:

4 - pound bag of pears for $14.08

Step-by-step explanation:

To find out which is the better deal, we have to simplify it.

By dividing $14.08 by 4, this gives us the amount of $ each pound costs, which is $3.52.

Now let's find out the amount of $ each pound costs for the 94- ounce bag of pears for $22.56.

First, we need to convert from ounces (oz) to pounds (lbs).

There are 16 ounces in one pound, and we have 94 ounces. So, 94/16 = 5.875 pounds. So there are 5.875 lbs in the $22.56 bag. Now we need to find the amount of $ each pound costs. So we divide $22.56 by 5.875 and we get $3.84.

$3.52 < $3.84 (this is the amount of money each pound of pears cost for each bag). The first bag is cheaper per pound, so they should buy the first one (which is the 4 pound bag btw).

Answer:

<S ≅ <G

Step-by-step explanation:

Given that ∆SAT ≅ ∆GRE, the following corresponding angles of both triangles would be congruent to each other:

<S ≅ <G

<A ≅ <R

<T ≅ <E

Therefore the option that completes the congruence statement given in the question would be:

<S ≅ <G

Answer:

x^2-6x+8

Step-by-step explanation:

Put it in intercept form and distribute

Answer:

1 1/2

Step-by-step explanation:

1/4 + 1/3 + 11/12

Multiplying the equations to have a common denominator (12).

1/4 times 3 = 3/12

1/3 times 4 = 4/12

3/12 + 4/12 + 11/12

Then add.

18/12

Then convert to mixed fraction.

1 6/12

Then simplify the fraction.

1 1/2

=1×4/4×3+1×4/3×4+11/12

=3/12+4/12+11/12

=3/2

Answer:

0

Step-by-step explanation

well at least thats my guess!

we have to go by bidmas. so you substitute first!

so its going to be: 3(-1)(4(-1)+5)+3

all I did is that I replaced all p's by -1 and then you multiply it!

so its gonna be: -3(-4+5)+3

you first solve what's in the brackets which is -4+5 so the answer is 1 like this: -3(1)+3 now its much simpler. all we have to do is to expand the bracket so its going to be -3+3 so the answer is 0!

It should be the second one

Step-by-step explanation:

Because in cubic inches it is 1,000.

Answer:

ariel is incorrect because 2 5/8 is equal to 2.63

Step-by-step explanation:

The correct decimal value is 2.63

We have Ariel who incorrectly said that [tex]2\frac{5}{8}[/tex]  is the same as 2.58

We have Convert  [tex]2\frac{5}{8}[/tex]  into a decimal correctly.

The method to convert the mixed fraction to normal fraction is -

[tex]$\frac{y\times a + x}{y}[/tex]  

According to question, we have -

Mixed fraction =  [tex]2\frac{5}{8}[/tex]  = [tex]\frac{21}{8}[/tex] = 2.625 = 2.63

Hence, the correct decimal value is 2.63

Answer:

The required probability =  0.5385

Step-by-step explanation:

The no. of cards in a deck = 52

The event of having  3 in a draw of a single card = 4/52

The event of having a black card in a draw of a single card = 26/52

The event of having  a black card and 3s = 2/52

Let T represent the event of having  3.

U to represent the event of having  a black card; &

V to represent the event of having  a black card that is 3s

Then the probability that it will be a 3 or a black card is;

P( T or U) = p(T) + p(U) - p(T and U)

P( T or U) = 4/52 + 26/52 - 2/52

P( T or U) = (4+26-2)/52

P( T or U) = 28/52

P( T or U)= 7/13

P( T or U) = 0.5385
