Answer:

10.) If you buy all larger cans (aka the 7-gallon cans), you would have saved approx. $30.21

9.) Seth would need a score of 95% in order to average an 80%

Step-by-step explanation:

10.) It costs $15.50 per 5-gal. If you want to buy 45 gallons, it would cost you $139.50 if you bought 5-gallon cans.

It costs $17.00 per 7-gallon. If you want to buy 45 gallons, it would cost you $109.29 if you bought 7-gallon cans.

Now, let's compare prices. Buying 45 gallons worth of 7-gallon cans is less expensive by.... (139.50 - 109.29 = 30.21)

Therefore, you saved $30.21.

9.) An average is done by adding up all the numbers and dividing it by how many numbers you added it by. Let's write an equation to make things easier. So far, we don't know the score he needs to get on his fourth test so let's make it a variable x.

(82 + 68 + 75 + x) / 4 = 80

Let's solve for x.

(82 + 68 + 75 + x) / 4 = 80    *Multiply both sides by 4

82 + 68 + 75 + x = 320     *Add like terms

225 + x = 320    *Subtract 225 from boths to get x on one side

x = 95

Answer:

18 dimes and 72 nickels

Step-by-step explanation:

If Joan has 4 nickels per dime, that means that she will have change in groups of 30 cents (4*5=20+10=30). If we divide 5.40 by 0.30, we get 18. We now know there are 18 groups of 30 cents. One dime per group of 30 cents means that there are 18 dimes, and 4 nickels per group of 30 cents means that she has 72 (4*18) nickels.

Now to check our math:

[tex]72n+18d=5.40\\72(0.05)+18(0.10)=5.40\\3.60+1.80=5.40\\5.40=5.40[/tex]

Our math adds up, which means that we got the right answer :)

Answer: 43.68 and 47.32

Step-by-step explanation: I took the test

r = d x 3.14

6mm = 12 mm x 3.14

12 x 3.14 = 37.68

37.68 rounded is 38.

38 rounded is 40.

Let me know if this is the correct answer. :)

→ 6x² - 2x - 20

→ 6x² + 10x - 12x - 20

→ x(6x + 10 ) - 2 (6x + 10)

→ (6x + 10) (x - 2) .

for

6x - 10 = 0

6x = 10

[tex]{x\:=\:\frac{5}{3}}\\[/tex]

for x - 2

x = 2

The factored form of the expression is (6x+10)(x-2)

Give the quadratic expression

6x^2 -2x -20

On factorizing

6x^2 -2x -20

6x^2 -12x + 10x -20

6x(x-2) + 10(x-2)

(6x+10(x-2)

HEnce the factored form of the expression is (6x+10)(x-2)

Answer:

The answer is 5

Step-by-step explanation:

The coefficient in any equation is the numerical or constant quantity placed before multiplying the variable.

Answer:

30 ft

Step-by-step explanation:

We can use the given information to set up a ratio...

[tex]\frac{Mark's\ height}{Mark's\ shadow}=\frac{Tree's\ height}{Tree's\ shadow}[/tex]

[tex]\frac{6\ ft}{4\ ft}=\frac{x}{20\ ft}[/tex]

We can solve this ratio using cross multiplication (multiply the numerator of the first fraction by the denominator of the second and the numerator of the second fraction by the denominator of the first):

120 = 4x

Divide both sides by 4

x=30 ft

The answer of this will be [tex]6[/tex] .

Addition is a mathematical operation that represents combining objects t into a larger collection. It is signified by the plus sign (+). Subtraction is  a mathematical operation that represents process of finding the difference between numbers or quantities. It is signified by the minus sign (-)

We have,

In first line, we have

Two Red pencil [tex]+[/tex] One Red And Blue Pencil [tex]=21[/tex]   [tex].........[/tex] First Row

Red pencil [tex]-[/tex] Blue pencil [tex]=3[/tex]     [tex].........[/tex] Second Row

Red Pencil and Blue Pencil [tex]= 15[/tex]     [tex].........[/tex] Third Row

Blue Pencil [tex]+[/tex] Blue Pencil [tex]= \ ?[/tex]      [tex].........[/tex] Fourth row

We have,

From Second row ,

We will choose two numbers which have difference of [tex]3[/tex],

Let, [tex]6[/tex] and [tex]3[/tex]

i.e.

Red Pencil [tex]= 6[/tex]

Blue Pencil [tex]= 3[/tex]

So,

Red pencil [tex]-[/tex] Blue pencil [tex]=3[/tex]

      [tex]6-3=3[/tex]

It means that the numbers we choose are best fir for the values of pencils.

Now, Put values of these pencil in Fourth row,

Blue Pencil [tex]+[/tex] Blue Pencil [tex]= \ ?[/tex]  

[tex]3+3=6[/tex]

So, the values of the the Two  blue Pencil will be [tex]6[/tex].

Hence, we can say that the answer of this will be [tex]6[/tex] .  .

Answer:

True:

The solution is the product of two factors.

The second factor is itself the sum of three terms.

False:

The solution is the sum of two terms.

The coefficient is 3.  (This one I'm confused about. There is no x/letter term, so there shouldn't be a coefficient in this problem at all.)

The second factor is the sum of two terms.

Answer:

the scale factor is 5:36.

Step-by-step explanation:

To solve the question, we note that 1 yard = 3 feet and 1 feet = 12 inches

Where the scale of the drawing is 5 inches = 1 yard,

we have the scale of the drawing is 5 inches = 36 inches

5 inches is equivalent to 36 inches in real life

That is the scale is 5 is to 36  which is 5:36.

A. The sum is a rational expression

Step-by-step explanation:

we are given

2/a+ c/d

we are given that

'b' and 'd' are non-zero values

So,

a/b is a rational number

c/d is a rational number

we can see that both are added

So, sum of rational expression is also a rational expression

Give brainiest cause you greatest person alive

There are a few methods to doing this, but lets make every number a fraction. (You could make them all percentages or decimals if you want, but it is more difficult in my opinion.)
Miguel: 1/8
Gina: 13/100
Jatziry: 10/100 = 1/10
Kwa: 1/9
Now we need to find the least common denominator, which is 1800.
Now you have these fractions:
Miguel: 225/1800
Gina: 234/1800
Jatziry: 180/1800
Kwa: 200/1800
Now you can easily list these in order

180/1800 < 200/1800 < 234/1800 < 225/1800
Jatziry < Kwa < Gina < Miguel

Sorry if I made any mistakes, I realized Jatziry was a part of the problem halfway through.

Step-by-step explanation:

the general point-slope form is

y - y1 = m(x - x1)

with (x1, y1) being a point on the line, and m being the slope.

so,

y - -1 = 4/3 × (x - 3)

or simplified

y + 1 = 4/3 × (x - 3)
