Answer:

square root of 1625 is 40.311 or 40 as a whole number

Step-by-step explanation:

Answer:

40.3112887... simplify to 40.311, 40.31, or 40.3, depending on rounding.

Answer:

b = 4

r = 3

Step-by-step explanation:

r + b = 7

solve for 'r' to get r = 7-b

now substitute '7-b' for r in the second equation:

3.75(7-b) + 2.75b = 22.25

26.25 - 3.75b + 2.75b = 22.25

-b = -4

b = 4

r = 3

Jared bought 3 cans of red paint (r = 3) and 4 cans of black paint (b = 4).

To solve this problem, using algebraic equations. Jared recently bought cans of red and black paint, and we want to find out how many cans of each color he purchased. We know that the cost of a red can is $3.75, the cost of a black can is $2.75, and Jared spent a total of $22.25 on the paint. We will set up two equations based on the given information and solve them simultaneously to find the values of "r" (number of red cans) and "b" (number of black cans).

Let's use the following variables:  

r  : Number of red cans purchased  

b : Number of black cans purchased

Now, we can set up two equations based on the information given in the problem:

1. The total number of cans purchased:  

  Since Jared bought 7 cans in total, we can write this as:

   r + b = 7  ... (Equation 1)

2. The total cost of the cans:  

  The cost of each red can is $3.75, so the total cost of all red cans is 3.75r. The cost of each black can is $2.75, so the total cost of all black cans is 2.75b. Jared spent a total of $22.25, so we can write this as:

    3.75r + 2.75b = 22.25  ... (Equation 2)

Now, we have a system of two equations with two variables. We will use the method of substitution or elimination to solve for r and b.

Using substitution, we can rearrange Equation 1 to solve for r:  

r = 7 - b

Now, we can substitute this value of r into Equation 2:

3.75(7 - b) + 2.75b = 22.25

Next, distribute and simplify the equation:

26.25 - 3.75b + 2.75b = 22.25

Combine the b terms:

-1b = 22.25 - 26.25

Simplify further:

-1b = -4

Finally, divide both sides by -1 to find the value of b:

b = 4

Now that we have the value of b, we can find r by substituting the value of b into Equation 1:

r + 4 = 7

Subtract 4 from both sides:

r = 7 - 4

r = 3

Therefore, Jared bought 3 cans of red paint (r = 3) and 4 cans of black paint (b = 4).

Step-by-step explanation:

Answer:

c

Step-by-step explanation:

3/5m - 15

3/5m - 15 = 0

Make 15 the subject of the formula

3/5m = 15

the above equation can be interpreted as

3/5 times m is equal to 15

The sum of 3/5 and a number is 15 would be represented as 3/5 + m = 15

Three-fifths more that a number is 15 would be represented as 3/5m + m = 15

Why are there so many ''' in your question? Do they have any signifigance?

The value of [tex]x[/tex] of the system of equations will be  [tex]-1[/tex].

System of equations is a finite set of equations for which common solutions are sought.

We have,

[tex]4x + 3y = 8[/tex]    

[tex]4x-3y = -16[/tex]

So,

Using the linear combination method,

i.e. adding the given equations,

[tex]4x + 3y = 8[/tex]    

[tex]4x-3y = -16[/tex]

We get,

[tex]8x=-8[/tex]

⇒

[tex]x=-1[/tex]

So, value of [tex]x[/tex] is [tex]-1[/tex] .

Hence, we can say that the value of [tex]x[/tex] of the system of equations will be  [tex]-1[/tex].

The graph C is correct, open holes at 1 and 3; shading in between.

In Algebra, inequality is a Mathematical statement that shows the relation between two expressions using the inequality symbol.

Given is an inequality, x-1 / x-3 < 0, we need to find the graph of it,

Let p = x-1 and q = x-3

Now,

The problem we want to solve is in the form p/q < 0

Since p/q is negative, there are two cases we have to address ;

Case 1) p is positive and q is negative, or,

Case 2) p is negative and q is positive

The signs of p and q are opposite one another.

Case 1) If p is positive, then

p > 0

x-1 > 0

x > 1

If q is negative, then

q < 0

x-3 < 0

x < 3

Combine x > 1 with x < 3 and we get 1 < x < 3.

Case 2) If p is negative, then

p < 0

x-1 < 0

x < 1

If q is positive, then,

q > 0

x-3 > 0

x > 3

We get a contradiction.

Both "p is negative" and "q is positive" must be true at the same time. But if p is negative, then x < 1 which contradicts x > 3 (which happens when q is positive)

Put simply: case 2 is not possible. There's no way to have p be negative at the same time q is positive. This because we're wanting x to both be smaller than 1 AND also be greater than 3 at the same time.

We must rule out case 2 and side with case 1 instead.

The conclusion of case 1 was that 1 < x < 3

The graph of this has open holes at 1 and 3 on the number line. The shading is between the open holes to represent all values between 1 and 3, excluding the endpoints.

Hence, the graph is C.

Answer:

The dimensions of the rectangle are:

2a^2b^2 and 3ab^2 + 5a + 7b

Step-by-step explanation:

The question is asking for the length and width of the rectangle, and gives you an equation that shows the area of the rectangle. It says to factor out the  GCF to find these dimensions. In simpler terms, the question wants you to divide the equation for the area, 6^3b^4 + 14a^2b^3 + 10a^3b^2, into two different equations for the length and width, which can't be divided more.

We have three terms to find the greatest common factor (GCF) of. 6^3b^4, 14a^2b^3, and 10a^3b^2. First, let's factor out the 2. This leaves us with

2(3^3b^4 + 7a^2b^3 + 5a^3b^2)

It seems like we're done with factoring out coefficients, for 3, 5, and 7 are all prime. Now, variables. Each term has a factor of a^2b^2. (not more, for this is the limit of  14a^2b^2.)

2a^2b^2(3ab^2 + 7b + 5a) .   (this is the same as the answer above, but I changed the order of 7b and 5a there because some online things are specific and don't like it if you don't put the equations in order.)
