Answer:

43.65  grams of bird feed containing 5% seed must be added to get bird feed that is 40% seed

Step-by-step explanation:

Let us assume the total capacity of the container  = m grams

Here, given: 80% of m = 100 grams

[tex]\implies \frac{80}{100} \times m = 100\\\implies m = \frac{100 \times 100}{80} = 125[/tex]

or, the TOTAL CAPACITY of container  = 125 grams

Now, the container already has 5 % seeds.

Calculating 5% of the capacity, we get:

[tex]\implies \frac{5}{100} \times 125 = 6.25[/tex]

So, the container already has 6.25 grams.

Now, the total filling of the container should be 40%.

Calculating 40% of the capacity, we get:

[tex]\implies \frac{40}{100} \times 125 = 50[/tex]

So, the weight of seeds that NEEDS To be in total  = 50 grams.

Also, it already has  6.35 grams.

So, the weight of seeds to be added  = 50 grams - 6.35 grams

                                                                   = 43.65 grams

Hence, 43.65  grams of bird feed containing 5% seed must be added to get bird feed that is 40% seed.

43.75  grams of bird feed containing 5% seed must be added to get bird feed that is 40% seed  

Percentage is a number or ratio that can be expressed as a fraction of 100.

Let the total mass of the container = x

Therefore,

80% of x = 100g of bird feed

80 / 100 × x = 100

80x = 10000

x = 10000 / 80

x = 125 grams

Therefore, 5% volume will be as follows;

Therefore, 40% volume is as follows:

Finally, the weight to be added to make the bird feed 40% seed is as follows;

Answer:

(4,3)

Step-by-step explanation:

The orthocenter of a triangle is the point of intersection of the altitudes of the triangle .

The vertices are:

A(-2,5), B(6,5), and C(4,-1)

Slope of (6,5), and (4,-1) is

[tex]m = \frac{5 - - 1}{6 - 4} = 3[/tex]

Slope of altitude through A is

[tex] - \frac{1}{3} [/tex]

The equation of the altitude through A is

[tex]y - 5 = - \frac{1}{3} (x - - 2)[/tex]

[tex]y = - \frac{1}{3} x + \frac{13}{3} [/tex]

The slope of A(-2,5), B(6,5) is zero because it is a horizontal line.

The equation of altitude through (4,-1) will be the vertical line x=4.

This implies that,

[tex]y = - \frac{4}{3} + \frac{13}{3} = 3[/tex]

Hence the orthocenter is (4,3)

Answer:

y = - 5x

Step-by-step explanation:

Given that y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = - 10 when x = 2, thus

k = [tex]\frac{y}{x}[/tex] = [tex]\frac{-10}{2}[/tex] = - 5

y = - 5x ← equation of variation

Answer:

Length = 10.5units,Area = 68.25 unit²

Step-by-step explanation:

Perimeter =34 units

Width =6.5 units

Perimeter = l+l+w+w

Where l= length and w= width

34 = l + l + 6.5+ 6.5

34.= 2l + 13

Subtract 13 from both sides

2l = 34 - 13

2l = 21

Divide both sides by 2

L= 21/2

Length = 10.5units

If we are to find the area.

Area = length x width

Area = 10.5 × 6.5

Area = 68.25 unit²

Solving by method of factorization ,

(y^4-y^3+2y^2+y-1)/(y+1)(y^2-y+1)

Step-by-step explanation:

A sum of two perfect cubes,  a3 + b3 can be factored into  :

            (a+b) • (a^2-ab+b^2)

here a = y and b = 1

hence , expanding y^3+1 in cubic formula ,

(y^3+1) = (y+1)(y^2-(y)(1)-1^2)

(y^3+1)=(y+1)(y^2-y+1)

putting this value of (y^3+1) in the given expression ,

= (y^4-y^3+2y^2+y-1)/(y+1)(y^2-y+1).

Trinomial cannot be factored , hence the final answer is ,

= (y^4-y^3+2y^2+y-1)/(y+1)(y^2-y+1).

The volume of cylinder is 1205.76 cubic inches

Solution:

We have to find the volume of cylinder

The volume of cylinder is given by formula:

[tex]V = \pi r^2h[/tex]

Where "r" is the radius and "h" is the height of cylinder

Given dimensions are:

Radius = 8 inches

Height = 0.5 feet

Convert feet to inches

1 feet = 12 inches

Therefore,

0.5 feet = 12 x 0.5 = 6 inches

Thus, we have got,

height = 6 inches

Substitute r = 8 inches and h = 6 inches in formula:

[tex]V = 3.14 \times 8^2 \times 6\\\\V = 3.14 \times 64 \times 6\\\\V = 1205.76[/tex]

Thus volume of cylinder is 1205.76 cubic inches

Answer:

18 and 335

Step-by-step explanation:

y = 18x + 11

x * y = 6030

x * (18x + 11) = 6030

18x^2 + 11x = 6030

18x^2 + 11x - 6030 = 0

(18x + 335)(x - 18) = 0

18x + 335 = 0                 x - 18 = 0

18x = -335                      x = 18

x = -335/18

x is gonna have to be a positive number...so x = 18

y = 18x + 11

y = 18(18) + 11

y = 324 + 11

y = 335

so ur numbers are 18 and 335

The two positive integer numbers are 18 and 335

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the two numbers be a and b

Now ,

Positive integer is 11 more than 18 times another

a = 11 + 18b   be equation (1)

And , product of a and b is 6030

a x b = 6030   be equation (2)

Now , substituting the value of equation (1) in equation (2) , we get

( 11 + 18b ) x b = 6030

18b² + 11b = 6030

Subtracting 6030 on both sides , we get

18b² + 11b - 6030 = 0   be equation (3)

On simplifying , we get

18b² - 324b + 335b - 6030 = 0

18b ( b - 18 ) + 335 ( b - 18 ) = 0

So ,

( 18b + 335 ) ( b - 18 ) = 0

Now , we got two values for b ,

( 18b + 335 ) = 0

b = -335 / 18

And ,

( b - 18 ) = 0

b = 18

Since , b is a positive integer , the value of b is 18

Now , substituting the value of b in equation (2) , we get

a x 18 = 6030

Divide by 18 on both sides , we get

a = 335

Hence , the two positive integer numbers are 18 and 335

Answer:

P - 4

Step-by-step explanation:

Sergio and the other painting collectors have decided to donate a total of 48 paintings all together.

We know that there are 12 collectors in total and they will each donate the same number of paintings.

48 paintings in total

12 collectors

48 / 12 = 4

We now know Sergio will donate 4 paintings from his collection of P paintings. Sergio will have P - 4 paintings left.

We do not know what "P" is equal to, so we cannot give an exact number for how many paintings he will have left. However, we know he will have 4 fewer paintings after donating.

84 pounds of Type B coffee is used

Solution:

Let "x" be the pounds of type A coffee

Let "y" be the pounds of type B coffee

Cost per pound of type A = $ 5.50

Cost per pound of Type B = $ 4.20

This month, Chau made 143 pounds of the blend

x + y = 143

x = 143 - y -------- eqn 1

For a total cost of $677.30. Thus we frame a equation as:

pounds of type A coffee x Cost per pound of type A + pounds of type B coffee x Cost per pound of Type B = 677.30

[tex]x \times 5.50 + y \times 4.20 = 677.30\\\\5.5x + 4.2y = 677.30 -------- eqn 2[/tex]

Let us solve eqn 1 and eqn 2

Substitute eqn 1 in eqn 2

[tex]5.5(143-y) +4.2y = 677.30\\\\786.5 -5.5y + 4.2y = 677.30\\\\5.5y - 4.2y = 786.5 - 677.30\\\\1.3y = 109.2\\\\Divide\ both\ sides\ by\ 1.3\\\\y = 84[/tex]

Thus 84 pounds of Type B coffee is used

To determine how many pounds of type B coffee were used in Chau's coffee blend, we set up a system of equations based on the total weight and total cost of the blend. By substituting one equation into the other, we can solve for the quantity of type B coffee.

Calculating the Blend of Coffee:

To solve the problem, let's use a system of equations to determine how many pounds of type B coffee Chau used in his coffee blend. We have two unknowns here: the amount of type A coffee (let's call it A) and the amount of type B coffee (let's call it B). The total weight of the coffee blend is given as 143 pounds, and the total cost of the blend is $677.30.

The first equation comes from the total weight of the blend:

A + B = 143

The second equation comes from the total cost:

5.50A + 4.20B = 677.30

We can use either substitution or elimination to solve this system. If we solve the first equation for A (i.e., A = 143 - B) and substitute it into the second equation, we get:

5.50(143 - B) + 4.20B = 677.30

After simplifying, we can solve for B to find out how many pounds of type B coffee were used.

The expression demonstrates distributive property.

(8,8)

Step-by-step explanation:

The image point of (3,7) after translation 5 units to the right and 1 unit up is (8,8).

Translation of a point in a coordinate plane involves moving the point to a new location without changing its orientation or size.

To find the image of a point (3,7) after a translation of 5 units to the right and 1 unit up, we simply add the translation amounts to the original coordinates.

For a rightward movement, we add 5 to the x-coordinate, and for an upward movement, we add 1 to the y-coordinate.

Therefore, the new position of the point after translation will be:

So, the image point after the translation is (8,8).

Infinitely many solutions

Step-by-step explanation:

If we have a system of equation like:

2x+y=4

6x+3y=12

If we make y the subject in the first equation and substitute into the second equation, we get:

6x+3(4-2x)=12

We expand to get:

6x+12-6x=12

6x-6x+12=12

Now the variable adds out to give:

12=12

This statement is true so the equation has infinitely many solution.

Answer:

Explanation:

When the variable adds out means that after all the simplifications, at the end, it will not appear in the final sentence or expression.

Then, if the final sentence is true, and not variable appears, but only constants, the sentence is always true, no matter what value the variable takes.

That means that you can put any value for the variable in the original equation and the equation will be true; hence there are infinite solutions.

This is an example:

1. Equation:
