A different aquarium should contain 15,000 liters of water when filled correctly. It will overflow if it gets to 17,600 liters.

One day there is an accident and the tank cracks in 4 places. Water flows out of each crack at a rate of liter per hour. An emergency pump can re-fill the tank at a rate of 2 liters per minute. How many minutes must the pump run to replace the water lost each hour?

Answer:

Step-by-step explanation:

The awnser must be c, since you can only get a quadratic polynomial function if you derive a polinomial of the 4th degree twice. C is the only polynomial of the 4th degree here, the other ones are of the 3rd degree.

The answer would be the first one, combining 8 and -2

This is because the 2 like terms are 8x^2 and -2x^2. You can get this by looking in the problem. There are 2 terms with x^2 which means we have to combine them. One of them is 8x^2 (the 1st one) and the other is -2x^2 (since it says 7-2x^2)

If you combine these you will get 6x^2 [8+(-2)=6]

Answer:

Answer:

Option D: -2x-10 is the correct answer.

Step-by-step explanation:

Given expression is;

-2 (x+5)

We will solve the expression by multiplying -2 with the terms inside the brackets.

Therefore,

Multiplying -2 with the terms

-2*x + 5* -2

-2x + (-10)

-2x - 10

Hence,

Option D: -2x-10 is the correct answer.

Answer:

one chocolate cake=?=x

one lemon cake=?=y

$270 spent

need to buy total of 18 cakes

1-chocolate cake =$7

lemon cake = $5

cakes 18=x+y

money $110=$7x+$5y

When i graphed it on the demos calculator i got (10,8).

So 10= the number of chocolate cake brought and 8= the number of lemon cake brought

The number of lemon cakes Jasmine can buy for the party is 8.

Two equations can be deduced from the question:

a + b = 18 equation 1

$7a + $5b = $110  equation 2

Where:

In order to determine the number of lemon cakes that can be bought, take the following steps:

Multiply  equation 1 by 7

7a + 7b = 126  equation 3

Subtract  equation 2 from  equation 3

2b = 16

b = 8

Answer:

x = 12

Step-by-step explanation:

We know that the integers are consecutive. This means that they can be written as:

x, x + 1, and x+2.

First Integer: x

Second Integer: x + 1

Third Integer: x + 2

It is also given that the sum of the first integer and twice the second is 80 minus three times the third.

Write as an equation:

First Integer + 2(Second Integer) = 80 - 3(Third Integer)

Substitute:

x + 2(x+1) = 80 - 3(x+2)

Multiply:

x + 2x + 2 = 80 - 3x - 6

Simplify:

3x + 2 = 74 - 3x

Add 3x to both sides of the equation:

6x + 2 = 74

Subtract 2 from both sides of the equation:

6x = 72

Divide both sides of the equation by 6:

x = 12

Let me know if you have any questions about my explanation!

Answer:

Step-by-step explanation:

According to question ,

• First Integer → x

• Second Integer → x + 1

• Third Integer → x + 2

Now question says that the sum of the first and twice the second is 80 minus three times the third that means ,

→ x + 2 ( x + 1 ) = 80 - 3 ( x + 2 )

→ x + 2x + 2 = 80 - 3x - 6

→ 3x + 2 = -3x + 74

→ 3x + 3x = 74 - 2

→ 6x = 72

→ x = 72/6

→ x = 12

Hence , value of x is 12 that means :

→ x = First Integer = 12

→ x + 1 = Second Integer = 13

→ x + 2 = Third Integer = 14

In all of these x is the smallest integer and hence 12 is the correct answer .

Answer:

x = 6

Step-by-step explanation:

Since, ∠1 ≅ ∠2

By angle bisector theorem,

[tex]\frac{AB}{BD}=\frac{AC}{CD}[/tex]

By substituting the measures of each side in the given ratio of the sides,

[tex]\frac{3}{x-4}=\frac{x}{4}[/tex]

12 = x(x - 4)

12 = x² - 4x

x² - 4x - 12 = 0

x² - 6x + 2x - 12 = 0

x( x - 6) + 2(x - 6) = 0

(x + 2)(x - 6) = 0

x = -2, 6

Since, measure of the sides can't be negative, x can not be negative.

Therefore, x = 6 will be the answer.

3 minutes and 42 seconds

Step-by-step explanation:

So I would convert that minute into seconds

7*60=420

So 420+24=444

Divide by 2

444/2=222

Now divide by 60 to convert it back to minutes

222/60= 3.7

3.7 minutes or

7/10*60=42

3 minutes and 42 seconds

Answer:

1.5

Step-by-step explanation:

Vertical angles are congruent so:

7x=8x-12

Subtract 7x from both sides:

Answer:

Since the value is always multiplied by the same factor(19), the relationship is proportional.

Step-by-step explanation:

To see if the equation represents a proportional relationship, we see if the division of y by x is always the same

[tex]x = 1, y = 19*1 = 19[/tex]

[tex]x = 2, y = 19*2 = 38[/tex]

[tex]x = 3, y = 19*3 = 57[/tex]

So

[tex]\frac{57}{3} = \frac{38}{2} = \frac{19}{1} = 19[/tex]

Equal, so proportional

Answer:

m = 0

Step-by-step explanation:

1/2(-1.4m+0.4)=m+0.2

We move all terms to the left:

1/2(-1.4m+0.4)-(m+0.2)=0

Domain of the equation: 2(-1.4m+0.4)!=0

m∈R

We get rid of parentheses

1/2(-1.4m+0.4)-m-0.2=0

We multiply all the terms by the denominator

-m*2(-1.4m+0.4)-(0.2)*2(-1.4m+0.4)+1=0

Wy multiply elements

-2m^2(--(0.2)*2(-1.4m+0.4)+1=0

We use the square of the difference formula

-2m^2(+(0.2)*2(-1.4m+0.4)+1=0

Answer:

The greatest common factor (GCF) of these two monomials is [tex]16\, a[/tex].

Step-by-step explanation:

Rewrite [tex]32\, a[/tex] and [tex]48\, a[/tex] as the products of the variable [tex]a[/tex] and and prime number factors:

Write an expression for the GCF of these two monomials in terms of these factors ([tex]2[/tex]'s, [tex]3[/tex], and [tex]a[/tex].) Try to include as many of each factor as possible, as long as the resulting product is present in both monomials.

For example, there are five factor [tex]2[/tex]'s in the first monomial but only four in the second monomial. Therefore, include the factor [tex]2\![/tex] in the GCF for only four times.

The factor [tex]a[/tex] appeared once in both monomials. Hence, include [tex]a\![/tex] for one in the expression for the GCF.

On the other hand, the factor [tex]3[/tex] is found in the second monomial but not in the first. Therefore, this factor should not be included in the expression for the GCF.

Therefore, the expression for the GCF would be:

[tex]2 \times 2\times 2\times 2 \times a = 16\, a[/tex].
