Answer:

m = - 8 ± 6[tex]\sqrt{2}[/tex]

Step-by-step explanation:

Given

m² + 16m - 8 = 0 ( add 8 to both sides )

m² + 16m = 8

To complete the square

add ( half the coefficient of the m- term )² to both sides

m² + 2(8)m + 64 = 8 + 64

(m + 8)² = 72 ( take the square root of both sides )

m + 8 = ± [tex]\sqrt{72}[/tex] = ± [tex]\sqrt{36(2)}[/tex] = ± 6[tex]\sqrt{2}[/tex]

Subtract 8 from both sides

m = - 8 ± 6[tex]\sqrt{2}[/tex]

Final answer:

There are 13.5 cups of vegetables in the soup.

Explanation:

If the ratio of chicken to vegetables in a soup is 2:3, and there are 9 cups of chicken, we can find the number of cups of vegetables by setting up a proportion. According to the ratio, for every 2 cups of chicken, there are 3 cups of vegetables. Since we have 9 cups of chicken, we want to know how many cups of vegetables correspond to this amount.

Write the ratio of chicken to vegetables as a fraction: 2/3.

Set up a proportion where 2 cups of chicken is to 3 cups of vegetables as 9 cups of chicken is to x cups of vegetables.

2/3 = 9/x

Cross multiply to solve for x: 2x = 9 × 3

2x = 27

Divide both sides by 2 to solve for x: x = 27/2

x = 13.5

Therefore, there are 13.5 cups of vegetables in the soup.

Answer:

29 feet

2.6 seconds

Step-by-step explanation:

h(t) is a downwards parabola, so the maximum is at the vertex.

t = -b / (2a)

t = -40 / (2×-16)

t = 1.25

h(1.25) = -16(1.25)² + 40(1.25) + 4

h(1.25) = 29

When the ball lands, h(t) = 0.

0 = -16t² + 40t + 4

0 = 4t² − 10t − 1

t = [ -(-10) ± √((-10)² − 4(4)(-1)) ] / 2(4)

t = (10 ± √116) / 8

t = (5 ± √29) / 4

t is positive, so:

t = (5 + √29) / 4

t ≈ 2.6

The cube root of five to the seventh power can be rewritten as a rational exponent as five to the seven thirds power. This is achieved by making the denominator of the exponent the index of the radical and the numerator the power of the radicand.

In mathematics, radical expressions can be rewritten as expressions with rational exponents. In your case, the cube root of five to the seventh power, is represented as [tex]5^(^7^/^3^)[/tex], which is your rational exponent form. So the answer is C: five to the seven thirds power.

To convert a radical expression to an expression with a rational exponent, the denominator of the exponent becomes the index of the radical, and the numerator of the exponent becomes the power of the radicand. In this case, the cube root is the index, which is 3, and the power of the radicand (five) is 7. Hence, five to the seven thirds power.

There are 120 professors at the university

Step-by-step explanation:

At one really small university:

We need to find how many professors are at the university

Assume that the number of people the university is 100%

∵ 53% of the people in the university are undergraduates

∵ 37% of the people in the university are graduates

∵ There are 100% people in the university

- To find the rest subtract the sum of the undergraduates and

   graduates from 100%

∵ The rest = 100% - (53% + 37%)

∴ The rest = 100% - 90%

∴ The rest = 10%

∴ The rest is 10% from 1200 people in the university

∵ The rest are going for their doctorate

∴ The rest is the number of the professors in the university

∵ The rest is 10% from 1200 people in the university

∴ The number of professors = 10% × 1200

∵ 10% = 10 ÷ 100 = 0.1

∴ The number of professors = 0.1 × 1200

∴ The number of professors = 120

There are 120 professors at the university

The sum of three consecutive odd integers is 76 less then seven times the middle number. The three integers are 17, 19 and 21 respeectively

Since each consecutive odd integer is separated by a difference of  2

Let "n" be the first integer

n + 2 be the second integer

n + 4 be the third integer

Given that the sum of three consecutive odd integers is 76 less then seven times the middle number

Which means,

The sum of ( n, n + 2, n + 4) is equal to 76 less than seven times the middle number ( 7(n + 2))

That is,

n + n + 2 + n + 4 = 7(n + 2) - 76

3n + 6 = 7n + 14 - 76

4n = 68

n = 17

So we get:

First integer = n = 17

Second integer = n + 2 = 17 + 2 = 19

Third integer = n + 4 = 17 + 4 = 21

Thus the three consecutive odd integers are 17, 19 and 21 respeectively

Part A: The type of the quadrilateral of the rooftop is a square

Part B: The length of one side of the rooftop is 19 m

Step-by-step explanation:

Let us revise some notes about quadratic expression

The area of a rooftop can be expressed as 9x² + 6x +1

The rooftop is a quadrilateral

We need to find the type of the quadrilateral and the length of

one side of the rooftop

∵ The area of the rooftop = 9x² + 6x +1

- Check if 9x² + 6x +1 is a perfect trinomial

∵ [tex]\sqrt{9x^{2}}=3x[/tex]

∵ [tex]\sqrt{1}=1[/tex]

∵ [tex](3x)(1)(2)=6x[/tex]

∴ 9x² + 6x +1 = (3x + 1)²

∴ 9x² + 6x +1 is a perfect square trinomial

∵ Perfect square trinomial can represent the area of a square

∴ The quadrilateral is a square

Part A: The type of the quadrilateral of the rooftop is a square

∵ The area of the rooftop is 9x² + 6x +1

∵ 9x² + 6x +1 = (3x + 1)²

∵ Area of the rooftop = 361 m²

∴ (3x + 1)² = 361

- Take square root for both sides

∴ 3x + 1 = 19

∵ The area of a square = (side)²

∵ The area of a square = (3x + 1)²

∴ 3x + 1 is the length of the side of the square

∵ 3x + 1 = 19

∴ The length of the side of the square is 19 m

Part B: The length of one side of the rooftop is 19 m

The width of the rectangles is 4.

Step-by-step explanation:

Given that two rectangles have same width. So, let be the two rectangles [tex]R_{1}[/tex] and [tex]R_{2}[/tex] and width of rectangle is ‘x’. So, according to question, we have  

Length of one rectangle , [tex]R_{1}[/tex] = x + 1

Length of other rectangle, [tex]R_{2}[/tex] = x + 2

But we also know that,

                  [tex]\text { Area of rectangle } = \text { Length } \times \text { width }[/tex]

So,  then the area for one rectangle,

                [tex]\text { Area of rectangle } R_{1} = x \times(x+1)[/tex]

Similarly,

                [tex]\text { Area of rectangle } R_{2} = x \times(x+2)[/tex]

So, according to question,

                [tex]\text {Area of rectangle } R_{2} = 4 \times \text { Area of rectangle } R_{1}[/tex]

                [tex]x \times(x+2) = 4+x \times(x+1)[/tex]

Now, by solving the above equation, we get

                [tex]x^{2}+2 x = 4+x^{2}+x[/tex]

                [tex]x = 4[/tex]

So, from the above equation, we found that width of the rectangle is 4.

Step-by-step explanation:

A bakery makes 40 different flavors of muffins.

25% of the flavors have chocolate as one of the ingredients.

Convert 25% to fraction:

[tex]25\%=\dfrac{25}{100}=\dfrac{1}{4}[/tex]

So, there are

[tex]40\cdot \dfrac{1}{4}=10[/tex]

muffins which have chocolate as one of the ingredients.

In attached tape diagram:

green - with chocolate

blue - without chocolate

Answer:

Step-by-step explanation:

The total number of flavors is 40.

25% of the flavors have chocolate.

To find the number of flavors which have chocolate, we just need to multiply 0.25 by 40, because 0.25 represents 25%

[tex]0.25(40)=10[/tex]

So, there are 10 flavors with chocolate.

Now, if 25% represents flavors with chocolate, then 75% represents flavors without chocolate

[tex]0.75(40)=30[/tex]

So, there are 30 flavors without chocolate.

Price per pizza = $10

Price per cookie = $4

Minimum amount to be earned = $100

Price for 'p' pizzas sold = [tex]10p[/tex]

Price for 'c' cookies sold = [tex]4c[/tex]

As per question:

[tex]10p+4c\geq100[/tex]

Also, number of pizzas and cookies can't be negative. So,

[tex]p\geq0,c\geq0[/tex]

Answer:

4.5 sq. units.

Step-by-step explanation:

The given curve is [tex]y = (3x)^{\frac{1}{2} }[/tex]

⇒ [tex]y^{2} = 3x[/tex] ...... (1)

This curve passes through (0,0) point.

Now, the straight line is y = 3x - 6 ....... (2)

Now, solving (1) and (2) we get,

[tex]y^{2} - y - 6 = 0[/tex]

⇒ (y - 3)(y + 2) = 0

⇒ y = 3 or y = -2

We will consider y = 3.

Now, y = 3x - 6 has zero at x = 2.

Therefor, the required are = [tex]\int\limits^3_0 {(3x)^{\frac{1}{2} } } \, dx - \int\limits^3_2 {(3x - 6)} \, dx[/tex]

= [tex]\sqrt{3} [{\frac{x^{\frac{3}{2} } }{\frac{3}{2} } }]^{3} _{0} - [\frac{3x^{2} }{2} - 6x ]^{3} _{2}[/tex]

= [tex][\frac{\sqrt{3}\times 2 \times 3^{\frac{3}{2} }  }{3}] - [13.5 - 18 - 6 + 12][/tex]

Half the number of square root of a number is 2k is [tex]2k^2[/tex].

Let's break down the problem step by step to find half of the number. We start with the given information: the square root of a number is [tex]2k[/tex]. Our goal is to find half of this number.

Let the number be [tex]x[/tex]. The problem tells us that the square root of [tex]x[/tex] is [tex]2k[/tex].

We write this mathematically as:
[tex]\sqrt{x} = 2k[/tex]

To find [tex]x[/tex], we square both sides of the equation to remove the square root:
[tex]x = (2k)^2[/tex]

Simplify the right side:
[tex]x = 4k^2[/tex]

Now, we need to find half of [tex]x[/tex]. Half of [tex]x[/tex] is:
[tex]\text{Half of } x = \frac{x}{2} = \frac{4k^2}{2}[/tex]

Simplify the fraction:
[tex]\frac{4k^2}{2} = 2k^2[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange - 8x - 6y - 4 = 0 by adding 8x + 4 to both sides

- 6y = 8x + 4 ( divide all terms by - 6 )

y = - [tex]\frac{4}{3}[/tex] x - [tex]\frac{2}{3}[/tex] ← in slope- intercept form

with slope m = - [tex]\frac{4}{3}[/tex] and y- intercept c = - [tex]\frac{2}{3}[/tex]

To find the x- intercept let y = 0 in the equation and solve for x

- 8x - 0 - 4 = 0 ( add 4 to both sides )

- 8x = 4 ( divide both sides by - 8 )

x = - [tex]\frac{1}{2}[/tex] ← x- intercept

Step-by-step explanation:

24+0.44x=19+1.69x exp equation like:

24+44x/100=19+169x/100

Multiply left and right side of equation with 100

2400+44x=1900+169x

2400-1900=169x-44x

500=125x

x=500/125

x=4

The solution of the equation is 4.

To solve the equation 24+0.44x=19+1.69x, we want to collect like terms and isolate the variable x on one side. This type of equation is a linear equation, not a quadratic equation, since the highest power of x is one. First, let's move the terms containing x to one side and the constant terms to the other side:

Subtract 1.69x from both sides: 24 - 19 = 1.69x - 0.44x

Combine like terms: 5 = 1.25x

Divide both sides by 1.25: x = 5 / 1.25

Solving for x gives us: x = 4

Percent uncertainty is calculated by dividing the uncertainty value by the average value and then multiplying by 100 to get a percentage. In the example of a 5-lb apple bag with a 0.3-lb uncertainty, the percent uncertainty is 6%. If the bag's weight is halved but uncertainty remains unchanged, the percent uncertainty increases.

The question provided presents a situation requiring the calculation of percent uncertainty for the weight of bags of apples. The percent uncertainty is calculated as the uncertainty value divided by the average value, multiplied by 100 to convert it to a percentage.

For example, if a 5-lb bag of apples has an uncertainty of 0.3 lb, the percent uncertainty would be (0.3 lb / 5 lb) × 100%, which equals 6%. If the weight of the bag were to be halved while the absolute uncertainty remains the same, the percent uncertainty would increase.

This is because the same absolute uncertainty represents a larger proportion of a smaller number, thus increasing the percent uncertainty when converted into a percentage.

Answer: Square

The shape with four equal right angles and sides of the same length is a square, a fundamental concept in Euclidean geometry discussed in middle school mathematics.

The shape that has right angles and sides that are the same length is a square. In geometry, a square is a regular quadrilateral, which means that it has four equal sides and four equal angles (90-degree angles, or right angles). To identify a square, you can look for these two characteristics. .

The understanding of similar triangles is relevant when considering shapes and their properties, such as when using the properties of similarity to prove that two right triangles are similar based on their equal angles.

Step-by-step explanation:

The given is:

We need to write an equation that can be used to find c, and then

find the value of c

∵ The cost of the printer cartage = $c

∵ The computer game costs 15% more than a printer cartridge

- That means add the cost of the cartage by 15% of it to find the

   cost of the computer game

∴ The cost of the computer game = c + 15% × c

∵ 15% = 15 ÷ 100 = 0.15

∴ The cost of the computer game = c + 0.15 c

- The two terms of c (1 + 0.15)

∴ The cost of the computer game = $1.15 c

∵ The cost of the computer game = $40

- Equate the two expressions of the cost of the game

∴ 1.15 c = 40

The equation that can be used to find c is 1.15 c = 40

Solve the equation to find c

∵ 1.15 c = 40

- Divide both sides by 1.15

∴ c = $34.78

The cost of the printer cartridge is $34.78

Equation: 1.15 c = 40
