A recipe calls for 2/3 of a cup of milk for 11 cookies. How many cups of milk are needed to make 99 cookies?

Answer:

16

Step-by-step explanation:

the 9 parts of the ratio is equivalent to 72 books

divide number of books by 9 to find one part of the ratio

[tex]\frac{72}{9}[/tex] = 8 ← 1 part of the ratio

2 parts = 2 × 8 = 16 ← number of bookmarks sold

Answer:

(x, y ) = (3, 14 )

Step-by-step explanation:

since both equations express y in terms of x, equate the right sides

7x - 7 = 6x - 4 ( subtract 6x from both sides )

x - 7 = - 4 ( add 7 to both sides )

x = 3

substitute x = 3 into either of the 2 equations for y

using y = 6x - 4 = (6 × 3 ) - 4 = 18 - 4 = 14

solution is (3, 14 )

Answer:

23 packages

Step-by-step explanation:

We are told that the school cafeteria needs to buy 200 new forks. Each package contains 9 forks.

To find the number of packages that school cafeteria should buy we will divide total number of needed forks by number of forks in each pack.

[tex]\text{The number of fork packages}=\frac{200}{9}[/tex]

[tex]\text{The number of fork packages}=22.22222[/tex]

Since forks come in package of 9, so cafeteria have to buy whole number packages.

Let us round up our answer to the whole number.

[tex]\text{The number of fork packages}=22.22222\approx 23[/tex]

Therefore, school cafeteria should buy 23 packages of forks.

Answer:

23 packages should the cafeteria buy.

Step-by-step explanation:

Proportion states that the two ratios or fractions are equal.

As per the statement: The school cafeteria needs to buy 200 new forks. If each package contains 9 forks.

then by definition of Proportion;

[tex]\frac{1}{9} = \frac{x}{200}[/tex]   , where x represents the package

By cross multiply;

200 = 9x

Divide both sides by 9 we get;

[tex]\frac{200}{9} =\frac{9x}{9}[/tex]

Simplify:

[tex]x = \frac{200}{9} =22.222[/tex]

Therefore, 23 package should the cafeteria buy.

Answer:

15/64 = 23.4 %

Step-by-step explanation:

Let's consider the first two selections. Let's call B the case in which she extracts a boy and G the case in whish she extracts a girl.

For each selection, the probabilty of event B (selecting a boy) is

[tex]P(B)=\frac{12}{32}=\frac{3}{8}[/tex]

While the probability of event G (selecting a girl) is

[tex]P(G)=\frac{20}{32}=\frac{5}{8}[/tex]

We are asked to find the probability that the first two events are B and then G:

[tex]P(B,G)[/tex]

In the first two selections, we have 4 possible combinations:

BB, BG, GB, GG

The probability for each combination is given by:

[tex]P(BB)=P(B)\cdot P(B) = \frac{3}{8}\cdot \frac{3}{8}=\frac{9}{64}=14.1 \%[/tex]

[tex]P(BG)=P(B)\cdot P(G) = \frac{3}{8}\cdot \frac{5}{8}=\frac{15}{64}=23.4 \%[/tex]

[tex]P(GB)=P(G)\cdot P(B) = \frac{5}{8}\cdot \frac{3}{8}=\frac{15}{64}=23.4 \%[/tex]

[tex]P(GG)=P(G)\cdot P(G) = \frac{5}{8}\cdot \frac{5}{8}=\frac{25}{64}=39.1 \%[/tex]

The second one is the probability we are searching for, so the probability that she will select a boy first and then a girl is 15/64, or 23.4%.

Answer: at this amount, there are 57.5 calories per ounce

therefore, there are 355 calories in 6 ounces of this ice cream

(since 57.5×6=355.0)

Answer:

345 calories

Step-by-step explanation:

Total Calories = 230 calories

Total amount = 4 ounces

TO find how many calories in 6 ounces of the ice cream

For this question we have to find out the number of calories in one ounce of an ice cream firs

as it is given to us that 230 calories in 4 ounces

so no of calories in one ounce = total calories / no of ounces

                                                   =230 / 4

                                                   =57.5 calories / ounce

Now we know that their are 57.5 calories in one ounce of the ice cream

We have to find no of calories in 6 ounces of ice cream

No of calories = 6 * 57.5

                       =345 calories

so amount of calories in 6 ounces are 345 calories

First thing to do is solve the given equation for v

Assume we have a right trainload (looks like it but no angle indication given).  By the Pythagorean Theorem

p^2 + 5^2 = (p+1) ^ 2          =>

p^2 + 25 = p^2 + 2p + 1     =>

25 = 2p + 1                          =>         (subtract p^2 from both sides)

25 -1 = 2p                            =>         (subtract 1 from both sides)

If Circle A has a radius with the length of 5 units then the  exact length of the apothem is 5√3/2

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

Circle A has a radius with the length of 5 units.

We have to find the length of apothem

The formula of a height of an equilateral triangle

h=a√3/2

We have a = 5. Substitute:

h=5√3/2

Apply Pythagorean theorem.

(5/2)²+AH²=5²

25/4+AH²=25

AH²=25-25/4

AH²=75/4

Take square root on both sides

AH=5√3/2

Hence, if Circle A has a radius with the length of 5 units then the  exact length of the apothem is 5√3/2

Answer: (a) 5

Step-by-step explanation:

[tex]\lim_{x \to 2} 5[/tex] means what is the y-value when x = 2 .

The given equation is: y = 5 so the y-value is 5 for all values of x

Answer: (c) 13

Step-by-step explanation:

f(x) = x² + 5x

f'(x) = 2x + 5

f'(4) = 2(4) + 5

      = 8 + 5

      = 13

Answer: (c) 2

Step-by-step explanation:

The question is asking what the y-value is when x = -2.  The graph shows that the coordinate (-2, 2) is on the curve. So, when x = -2, y = 2.

Answer:

lim x→2   5     =5

The slope is 13

lim x→-2   x^2 -2  =2

Step-by-step explanation:

lim x→2   5     =5

The limit of a constant is the constant

f(x) = x^2 +5x

We need to take the derivative

f'(x) = 2x+5

Then evaluate the derivative at x=4  (4,36)

f'(4) = 2*4 +5

     = 8+5

    = 13

The slope is 13

lim x→-2   x^2 -2  =2

Looking at the graph, the value of the function at -2  is about 2

We can also calculate it   (-2)^2 -2 =  4-2 = 2

Answer:

k=3

Step-by-step explanation:

Given equation is

[tex]x^2+y^2 -6y-12=0[/tex]

First we move -12 to the other side by adding 12 on both sides

[tex]x^2+y^2 -6y =12[/tex]

We apply completing the square method to get square form (y-k)^2

Lets take coefficient of y and then divide it by 2

-6 divide by 2  is -3

Then we square it (-3)^2 = 9

We add 9 on both sides

[tex]x^2+y^2 -6y + 9=12+9[/tex]

[tex]x^2+(y^2 -6y + 9)=21[/tex]

Now we factor,  y^2 - 6y +9 is (y-3)(y-3)= (y-3)^2

[tex]x^2+(y-3)^3=21[/tex]

Now we compare with x^2 + (y-k)^2 = 21 and find the value of k

The value of k = 3

Water = 1/5 of the volume of the syrup

Step-by-.step explanation:

Suppose we had  1000 cm^3 of syrup  and the new volume after adding water is x cm^3.  Now the amount of sugar stays the same so we have the equation 35 * 1000 =  25 * x

x = (30 * 1000) / 25 =  30,000 / 25

= 1200 cm^3

So we need to add 200 cm^2 of water .

In general terms,  we need to add water which equals 1/5 of the volume of the syrup,

Answer:

This system will have a. exactly one solution.

Step-by-step explanation:

When two lines have different slopes it means that they intersect exactly one time.

If they have the same slope, we need to look at the intercept to see if there is none or infinitely many solutions.

However, these have different slopes and therefore have just 1 solution.

The given set of equations has exactly one solution as y = -1 and x = 2.

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

To put it another way, the equation needs to be subject to some restrictions.

A linear equation could contain more than one variable. If a variable's maximum power constantly equals one, an equation is considered to be linear.

Given a set of equations,

y = -3x + 5 and y = 3x - 7

By equate,

-3x + 5 = 3x - 7

6x = 12

x = 2 and y = -1

Hence "The given set of equations has exactly one solution as y = -1 and x = 2".

Answer:

Red grapefruit costs more per pound.

Step-by-step explanation:

Red grapefruit

y =2x

This is in the form y= mx+b  where m is the slope and b is the y intercept

The cost per pound is the slope, which is 2

The cost per pound is $2

Pink grapefruit

We need to find the slope

We have 2 points (0,0) and  (4,4)

m = (y2-y1)/(x2-x1)

   = (4-0)/(4-0)

   =4/4

  = 1

The slope is 1

The cost per pound is $1

Answer:

The red grapefruit.

Step-by-step explanation:

Let's think for a moment about what the equation [tex]y=2x[/tex] represents. For any value of x, our y is going to be double that. What do our y and our x represent, then? We're told that y represents the cost of the red grapefruit, and that x is the weight of that grapefruit in pounds. What our equation then tells us is that the cost (in dollars) of red grapefruit is always twice as much as its weight.

What about the pink grapefruit? Instead of an equation, we're given a line on a coordinate grid. Let's see if we can find a pattern here. The y axis is still cost, and the x axis is still weight. We see at the very beginning that when x = 0, y = 0 too. Finding a few more points, we can see that when x = 1, y = 1; when x = 2, y = 2; and when x = 3, y = 3. This pattern continues, and we can capture it with the equation [tex]y=x[/tex].

Comparing the two equations [tex]y=2x[/tex] (red grapefruit) and [tex]y=x[/tex](pink grapefruit) we can see that the cost of red grapefruit grows twice as fast as pink grapefruit. To see which one costs more per pound, we can simply set x = 1 to find that red grapefruit costs [tex]y=2(1)=\$2[/tex] per pound, while pink grapefruit costs [tex]y=\$1[/tex] per pound, and since [tex]\$2>\$1[/tex], the red grapefruit costs more.

The distance to the earth's horizon from point P is 216.2198187 mi, appriximately 216.22 mi

Step-by-step explanation:

This is a right triangle:

Hypotenuse: c=3959 mi + 5.9 mi → c=3964.9 mi

Leg 1: a=x=?

Leg 2: b=3959 mi

Using the Pytagorean theorem:

a^2+b^2=c^2

Replacing the known values:

(x)^2+(3959 mi)^2=(3964.9 mi)^2

Solving for x: Squaring:

x^2+15,673,681 mi^2=15,720,432.01 mi^2

Subtracting 15,673,681 mi^2 both sides of the equation:

x^2+15,673,681 mi^2-15,673,681 mi^2=15,720,432.01 mi^2-15,673,681 mi^2

x^2=46,751.01 mi^2

Square root both sides of the equation:

sqrt(x^2)=sqrt(46,751.01 mi^2)

x=216.2198187 mi

x=216.22 mi

The distance from the point P to the Earth’s horizon distance is approximately 216.22 mi.

To find the distance from the point P to the earth's horizon, we can use the concept of the earth's curvature.

The distance from the center of the earth to point P is the radius of the earth plus the distance from the center to the surface, which is 3959 + 3964.9 = 7923.9 miles.

The distance to the horizon can be found using the formula for the horizon distance, which is approximately equal to the square root of two times the product of the earth's radius and the total distance from P to the surface of the earth.

So, x = sqrt(2 * 3959 * 7923.9) = 216.22 mi.
