Answer:

154.34%

Step-by-step explanation:

We are asked to determine what percentage of 357 is 551.

Let us assume that x% of 357 is 551.

So, [tex]\frac{357 \times x}{100} = 551[/tex]

⇒ [tex]\frac{x}{100} = \frac{551}{357}[/tex]

⇒ [tex]x = \frac{551}{357} \times 100[/tex] ......... (1)

⇒ x = 154.34%

So, it is clear from the step (1) that when we take the basic ratio then multiply with 100, then we will get the percentage. (Answer)

Final answer:

To determine what percent 551 is of 357, divide 551 by 357, multiply by 100, and round to the nearest hundredth. The answer is 154.34%.

Explanation:

To find what percent 551 is of 357, we use the formula for calculating percentages: 'part over total, times one hundred, equals percent'. The 'part' in this case is 551, and the 'total' is 357.

The calculation is as follows:

Divide the part (551) by the total (357) which equals approximately 1.5434.

Multiply the result by 100 to find the percentage.

1.5434 × 100 = 154.34%

To round the final answer to the nearest hundredth, we look at the digit in the thousandths place. Since the third decimal place is 4, which is less than 5, we do not need to round up, so the rounded percentage is 154.34%.

Final answer:

To solve the system of equations -3x - 4y = 2 and 6x + 6y = -6, multiply the first equation by 2 to eliminate the coefficients of y, and then add the equations together. The solution is x = -2 and y = 1.

Explanation:

To solve the system of equations:

-3x - 4y = 2

6x + 6y = -6

First, multiply the first equation by 2 so that the coefficients of y will cancel when adding the equations together.

-6x - 8y = 4

Next, add the modified first equation to the second equation.

(-6x - 8y) + (6x + 6y) = 4 + (-6)

-8y + 6y = -2

-2y = -2

Divide both sides of the equation by -2 to solve for y.

y = 1

Substitute the value of y back into either equation to solve for x.

-3x - 4(1) = 2

-3x - 4 = 2

-3x = 6

x = -2

The solution to the system of equations is x = -2 and y = 1.

Answer:

x will be number of pounds

.5x is less than or equal to 6.50

She can afford 13 pounds of potatoes

You would solve the inequality by dividing each side by .5 to isolate x then write it as x is less than or equal to 13.

Part A:

You are given the amount of money Madison can spend and the price per pound for the potatoes. To find how many pounds Madison can buy, you would need to divide the amount of money she has by the price per pound.

The equation would be Pounds of potatoes = 6.50 / 0.50

Part B:

The only step required to solve the equation from part A is division.

Dividing 6.50 by 0.50 = 13. This means Madison can buy 13 pounds of potatoes.

Answer:

(x - 5)(x - 7)

Step-by-step explanation:

Given

x² - 12x + 35

Consider the factors of the constant term (+ 35) which sum to give the coefficient of the x- term (- 12)

The factors are - 5 and - 7, since

- 5 × - 7 = 35 and - 5 - 7 = - 12, thus

x² - 12x + 35 = (x - 5)(x - 7) ← in factored form

Answer:

The third number line

Step-by-step explanation:

first, make each fraction a complex fraction

47/10 = 4 7/10, so you know its the 7th dash from the left.

for 4 2/5 you need to make the denominator 10 by multiplying the numerator and denominator by 2 to get 4 4/10; this should be the 4th dash.

divide 24/5 to get 4 4/5. Multiply the numerator and denominator of the fraction part to get a denominator of 10. you should get 4 8/10; this is on the 8th dash from the last

You would have a dot on the 4th 7th and 8th dash altogether

Step-by-step explanation:

I'm pretty certain this is the answer, since 10/31 cannot be simplified any further; 31 being the total days in the month of May

A 10 days represent a fraction of approximately 0.3226 (rounded to four decimal places) of the month of May.

To find the fraction of the month that 10 days represent, we can divide the number of days represented by 10 by the total number of days in the month, which is 31.

Fraction = (Number of days represented) / (Total number of days in the month)

Fraction = 10 / 31

Therefore, 10 days represent a fraction of approximately 0.3226 (rounded to four decimal places) of the month of May.

The smallest integer is 1 and middle integer is 2 and largest integer is 3

Given that , three times the largest increased by two is equal to five times the smallest increased by three times the middle integer.

We have to find the three consecutive integers

So, let the smallest integer be n, then the next two consecutive middle and largest integers will be n + 1, n + 2 respectively

Then, by the given statement,  

Three times the largest increased by two is equal to five times the smallest increased by three times the middle integer.

[tex]\begin{array}{l}{3 \times (n+2)+2=5 \times n+3 \times (n+1)} \\\\ {3 n+6+2=5 n+3 n+3} \\\\ {8=5 n+3} \\\\ {5 n=8-3} \\\\ {n=1}\end{array}[/tex]

Thus the smallest integer = n = 1

Middle integer = n + 1 = 1 + 1 = 2

Largest integer = n + 2 = 1 + 2 = 3

Final answer:

We defined three consecutive integers as x, x+1, and x+2. By setting up the equation based on the given condition and solving for x, we find that the three consecutive integers are 1, 2, and 3.

Explanation:

Let's define the three consecutive integers we are looking for as x, x+1, and x+2, where x is the smallest integer, x+1 is the middle integer, and x+2 is the largest integer.

The problem states that three times the largest increased by two is equal to five times the smallest increased by three times the middle integer. This gives us the equation:

3(x+2) + 2 = 5x + 3(x+1)

Now, simplify and solve for x:

3x + 6 + 2 = 5x + 3x + 3

6x + 8 = 8x + 3

Subtract 6x from both sides:

8 = 2x + 3

Subtract 3 from both sides to isolate the term with x:

5 = 2x

Divide both sides by 2 to solve for x:

x = 5/2 = 2.5

Since x has to be an integer, this approach shows that we've made a mistake in our calculation. Let's try again:

3x + 6 + 2 = 5x + 3x + 3

3x + 8 = 8x + 3

5 = 5x

x = 1

So the three consecutive integers are 1, 2, and 3.

The slope of line perpendicular to given line is is 3/2 and y-intercept is: -1/2

Step-by-step explanation:

Given equation of line:

[tex]y = -\frac{2}{3}x+5[/tex]

The given equation of line is in slope-intercept form so the co-efficient of x will be the slope of the line

Let m_1 be the slope of given line

[tex]m_1 = -\frac{2}{3}[/tex]

As we know that the product of slopes of perpendicular lines is -1

Let m_2 be the slope of required line

So,

[tex]m_1.m_2= -1\\-\frac{2}{3} . m_2 = -1\\m_2 = -1 * -\frac{3}{2}\\m_2 =\frac{3}{2}[/tex]

The lope-intercept form is:

[tex]y =m_2x+b[/tex]

Putting the value of m2

[tex]y = \frac{3}{2}x+b[/tex]

To find the value of y-intercept, putting (5,7) in the equation

[tex]7 = \frac{3}{2}(5) + b\\7 = \frac{15}{2} + b\\7 - \frac{15}{2} = b\\b =\frac{14-15}{2}\\b = -\frac{1}{2}[/tex]

Putting the values of slope and y-intercept

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

Hence,

the slope is 3/2 and y-intercept is: -1/2

14.  c.  74 + w = 3w + 6; 34 pounds.

15.  b.  $42.5.

Step-by-step explanation:

13. 4 + 5x = 29

5x = 29-4 = 25

x = 5.

14. 74 + w = 3w + 6

68 = 2w

w = 34.

15. Let x be the money he got last year. Then:

2x + 5 = 90

2x = 85

x = $42.5.

For this case we have that by definition, the equation of the line in the slope-intersection form is given by:

[tex]y = mx + b[/tex]

Where:

m: It's the slope

b: It is the cut-off point with the y axis

According to the statement we have two points through which the line passes:

[tex](x_ {1}, y_ {1}): (- 3,4)\\(x_ {2}, y_ {2}) :( 1,0)[/tex]

We found the slope:

[tex]m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}} = \frac {0-4} {1 - (- 3)} = \frac {-4} { 1 + 3} = \frac {-4} {4} = - 1[/tex]

By definition, if two lines are perpendicular then the product of their slopes is -1.

Thus, a perpendicular line will have a slope: [tex]m_ {2} = \frac {-1} {- 1} = 1[/tex]

Thus, the equation will be of the form:

[tex]y = x + b[/tex]

We substitute the given point and find "b":

[tex]6 = -2 + b\\6 + 2 = b\\b = 8[/tex]

The value of k is -6

Step-by-step explanation:

The general form of the quadratic equation is y = ax² + bx + c

∵ 2x² + 11x = -k

- Add k to both sides

∴ 2x² + 11x + k = 0

∵ The roots of the quadratic equations is the values of x when y = 0

∵ [tex]\frac{1}{2}[/tex] is a root of the equation

- Substitute x by [tex]\frac{1}{2}[/tex] in the equation above to find k

∵ 2( [tex]\frac{1}{2}[/tex] )² + 11( [tex]\frac{1}{2}[/tex] ) + k = 0

Final answer:

By substituting x = 1/2 into the equation [tex]2x^2 + 11x = -k[/tex] and simplifying, we find that k must equal -6 for 1/2 to be a root of the equation.

Explanation:

To find the value of k such that 1/2 is a root of the quadratic equation [tex]2x^2 + 11x = -k[/tex], we can substitute x = 1/2 into the equation and solve for k.

First, substitute x = 1/2:

[tex]2(1/2)^2 + 11(1/2) = -k[/tex]

Then, simplify the equation:

2(1/4) + 11/2 = -k

1/2 + 11/2 = -k

Now, combine the terms:

(1 + 11)/2 = -k

12/2 = -k

6 = -k

Finally, multiply both sides by -1 to find k:

k = -6

They must sell 18 small pizzas, 12 medium pizzas and 6 large pizzas

Step-by-step explanation:

A Pizzeria sells pizza according to size:

We need to find how many of each size pizza they must sell to get $600

Assume that the number of small pizza is x, the number of medium pizza is y and the number of large pizza is z

∵ The Pizzeria sells x small pizzas, y medium pizzas and

   z large pizzas

∵ The small pizzas cost $10, medium pizzas cost $15, and

   large pizzas cost $40

∵ They get $600

∴ 10x + 15y + 40z = 600 ⇒ (1)

∵ They sell as many small pizzas as medium and large pizzas

   combined

∴ x = y + z ⇒ (2)

∵ The number of medium pizzas sold is twice as many as large ones

∴ y = 2z ⇒ (3)

Substitute equation (3) in equation (2) to find x in terms of z only

∵ x = (2z) + z

∴ x = 3z ⇒ (4)

Substitute x in equation (1) by equation (4), and substitute y in equation (1) by equation (3)

∵ 10(3z) + 15(2z) + 40z = 600

- Simplify the left hand side

∴ 30z + 30z + 40z = 600

- Add like terms

∴ 100z = 600

- Divide both sides by 100

∴ z = 6

Substitute the value of z in equations (3) and (4) to find y and x

∵ y = 2(6)

Answer:

y=4x+23

Step-by-step explanation:

The slope-intercept form of the equation of the line that passes through (-5,3) and is parallel to 12x-3y=10 is y = 4x + 23.

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.

Slope-intercept form:

y = mx + b, where m is the slope and b is the y-intercept.

And we have the given equation:

12x - 3y = 10

Arranging the equation as slope-intercept form.

3y = 12x - 10

Divide by 3,

y = 4x - 10/3.

And this line is parallel to the required line.

So, the slope of the required line;

m = 4

Hence, the slope-intercept form,

y = 4x+b  equation 1

To find y-intercept:

We substitute the value of x and y from the point (-5,3) to the slope-intercept form,

y = 4x + b

(3) = 4(-5) + b

b = 20 +3

b = 23

Now, the equation 1

y = 4x + 23

Answer:

420 cars were tested

Step-by-step explanation:

55/100=231/x

55x= 23100

x=420

Final answer:

The total number of cars tested can be calculated by dividing the number of cars that failed (231) by the percentage that failed (55%), resulting in 420 cars tested.

Explanation:

The question asks about the total number of cars tested based on the percentage that failed the safety test. To find the total, we can set up a proportion: if 55% of cars, or 0.55 of the total, failed the safety test and that number is 231, we can represent the total number of cars tested as 'X'. Using the proportion 0.55 = 231/X, we can solve for X, which represents the total number of cars tested.

Step by step, we can start by multiplying both sides of the equation by X to get 0.55X = 231, then we divide both sides by 0.55 to isolate X and find the total:

X = 231 / 0.55
X = 420

Therefore, 420 cars were tested.

Answer: 1/2

Step-by-step explanation: In this problem, we're tossing a coin and we want to find the probability of tossing a heads.

Now, let's find the probability of tossing a heads.

Remember that a coin has two sides which are heads and tails. When you flip a coin, each side is as likely to come up as the other. This means that the probability of flipping heads is the fraction 1/2.

Since the probability of flipping a heads is 1/2, we can also say that the probability of flipping a heads is 50%.

Therefore, the probability of flipping a heads on a fair coin is 1/2.
