Answer:

58.33 lbs.

Step-by-step explanation:

There are already 25 lbs of alloy of copper

Of this 25 lbs, 20% is pure i.e. copper content = 25(0.5) = 5lbs.

Now available is

Copper      Other metals

5 lbs                20 lbs

Let x lb of 30% copper is added.

Then new alloy will have 5+0.3x lb copper in total of 25+x lbs

Percentage pure = [tex]\frac{5+0.3x}{25+x} =27%[/tex]

Simplify to get

[tex]\frac{5+0.3x}{25+x} =\frac{27}{100} \\\\Cross multiply:\\27(25+x) =100(5+0.3x)\\500+30x =675 +27x\\3x = 175\\x = 175/3 = 58.33 lbs[/tex]

Hence answer is 58.33 lbs should be added.

The answer should be B or the second option. :)

the first option is the correct one

13/18 = 0.72

11/14 = 0.78

______

31

Second, we isolate the variable!

X + 0 = 31 - 5

X+0 = 26

X=26

Finally,Plug it in

26 + 5 = 57 - 26

26 + 5 = 31

31 = 31

Answer: 60!

It’s already answered but I need some points ✊

To find the answer, multiply the decimal by 10. 0.05 X 10 = 0.5, and since 0.05 goes into 0.5 10 times, it is equivalent to 1/10th of 0.5.

0.05 is 1/10 the value of 0.5.

In this question, we are given that 0.05 is 1/10 the value of something, and we need to find out what that something is. To solve this, we can set up an equation:

0.05 = 1/10 * x

To isolate x, we can multiply both sides of the equation by 10:

0.05 * 10 = 1/10 * 10 * x

0.5 = x

Therefore, 0.05 is 1/10 the value of 0.5.

Step-by-step explanation:

We have been given a number in expanded form [tex]5+0.1+0.03+0.006[/tex]. We are asked to write our given number in standard form.

To convert our given number in standard form, we will add all the values to get digits in tenths, hundredths and thousandths place as:

   0. 1

   0.03

+ 0.006

   5.136

Therefore, our given number in standard form would be 5.136.

ANSWER

The correct answer is D

EXPLANATION

The conditional is

"If an angle's measure is [tex]35\degree[/tex], then it is an acute angle"

The above statement is true because both the premise and the conclusion are true.

Now let us consider the inverse of the above statement.

"If an angle's measure is not[tex]35\degree[/tex], then it is not an acute angle"

The above statement is false.

For example [tex]60\degree[/tex] is an acute angle even though its measure is not [tex]35\degree[/tex]

Answer:

Equation of the line that it is perpendicular to y=7x-3 and passes through the origin is given by 7y + x = 0

Explanation:

  We have equation of line , y =7x -3, comparing it with y = mx +c

  So slope of line , m = 7

 We know that the product of slopes of perpendicular lines = -1

 So   m*Slope of perpendicular line = -1

        7* slope of perpendicular line = -1

        slope of perpendicular line = -1/7

 Given that the perpendicular line passes through origin (0,)0)

 We also know that equation of a line passing though origin is given by the expression, y = mx

 Here m = -1/7

 So equation of perpendicular line, y = -x/7

                   or      7y + x = 0

 Equation of the line that it is perpendicular to y=7x-3 and passes through the origin is given by 7y + x = 0

Answer:

B: P + 0.25 P

D : 5/4 P

Step-by-step explanation:

The price is P.

The tax is 25% of P, or 0.25P.

The total price is the price plus the tax,

P + 0.25P = P + 1/4P = 4/4P + 1/4P = 5/4P

A percentage is a number expressed fraction of hundred

The correct options for the expression that represent how much Jack pays in total are;

B: P + 0.25·P

D: (5/4)·P

Reason:

The given parameters are;

Material from which the pony is made = Diamond

Price of the pony = P dollars

Amount Jack has to pay as diamond pony tax = 25%

Required:

The expression that represents how much Jack pays per pony

Solution:

The amount Jack pays, A = The price of the pony + Tax

The amount paid as tax = 25% of P = 0.25·P

∴ A = P + 0.25·P

[tex]\therefore A = P + 0.25 \cdot P = P + \dfrac{1}{4} \cdot P = \dfrac{5}{4} \cdot P[/tex]

The correct options are; B: P + 0.25·P, and D: (5/4)·P

A principal square root of a real number is a positive real number (or a positive real number times i, if you're up to complex numbers, but let's assume not.)  It's not necessarily a positive integer, √2 being the obvious example.

Is √2 a positive fraction?   We can write it as √2 / 1 so I suppose it is.  It's certainly not a rational number.  Even if we grant irrationals as fractions surely √0=0 isn't a positive fraction.  So "always" isn't correct.

Out of 50 students, 11 are taking neither English nor Chemistry.

To find the number of students taking neither English nor Chemistry, we need to subtract the number of students taking English, the number of students taking Chemistry, and the number of students taking both from the total number of students. So, the number of students taking neither is:

Total number of students - Number of students taking English - Number of students taking Chemistry + Number of students taking both = 50 - 15 - 30 + 6 = 11.

Solution

Here the first term = -2

5th term = -1/8

Now we have to find the common ratio (r)

Fifth term A5 = -1/8

-1/8 = [tex]a_{1} r^{4}[/tex]

Here [tex]a_{1} = -2[/tex]

Plug in [tex]a_{1} = -2[/tex]  in the fifth term and find the value of r.

-1/8 = -2[tex]r^{4}[/tex]

r^4 = 1/16

Taking 4th root, we get

r = 1/2

Now let's find the second term.

first term *r = -2 *1/2 = -1

2nd term = first term * 1/2 = -1

3rd term = second term * 1/2 = -1 * 1/2 = -1/2

4th term = 3rd term *r = -1/2 *1/2 = -1/4

Hey there!!

Equations given :

y = x² - x - 20 -------- ( 1 )

y = 3x - 15 ------------ ( 2 )

Now, lets first solve for the 1st equation ...

... x² - x - 20

We can write -x as -5x + 4x

... x² + 4x - 5x - 20

... x ( x + 4 ) - 5 ( x + 4 )

... ( x - 5 ) ( x + 4 )

y = ( x - 5 ) ( x - 4 )

Now, let's solve the second equation ...

y = 3x - 15

... y = 3 ( x - 5 )

We have two equations, now getting them together..

3 ( x - 5 ) = ( x - 5 ) ( x - 4 )

Divide by x-5 on both sides

3 = x - 4

Add 4 on both sides

x = 7

The value of x is 7

Now substituting this, we get the value of y

We have,

y = 3x - 15

... y = 3(7 ) - 15

... y = 21 - 15

... y = 6

Hence, the ordered pair is ( 7 , 6 )

Hope my answer helps!

The ordered pair that serves as a solution to the given system of equations is found by setting the equations equal to each other, coupling the x-values with their corresponding y-values after calculation. The solutions are (5,0) and (-1,-18).

To find the ordered pair that is a solution to the system of equations y = x^2 - x - 20 and y = 3x - 15, we can set the two equations equal to each other and solve for the variable x.

So, the solutions to the system are (5,0) and (-1,-18).

(12x-14)-(3x+9)-(-4-1)

= 9x-18

12x-3x=9x

-14-9+4+1=-18

*Subtracting a group of numbers in parenthesis is the same as -1 times what every is in the parenthesis.

So it would be (12x-14)+(-3x-9)+(4+1)... which makes the equation alot easier to simplify.

The additive inverse of the number is the same number but with the opposite sign.

The number you are given is negative, so the additive inverse would be positive.

The answer is 10 1/4

The additive inverse of -10 1/4 is 10 1/4, as it is the number that results in zero when added to the original.

The additive inverse of a number is the number that, when added to the original, will result in zero. For the number -10 1/4, its additive inverse would be the opposite sign of that number. Therefore, the additive inverse of -10 1/4 would be 10 1/4.
