There were 35 bunche of roe and tulip. Each bunch had 12 of the ame flower. There 7 more bunche of tulip than roe. How many tulip were there?

Answer:

Step-by-step explanation:

directly proportional means same

x=y

512=128

64=y

512/64=8

128/8=16

when x=64 then the value of y=16

Answer:

C

Step-by-step explanation:

given y is directly proportional to x then the equation relating them is

y = kx ← k is the constant of proportion

to find k use the condition when x = 512, y = 128

128 = 512k ( divide both sides by 512 )

[tex]\frac{128}{512}[/tex] = k , that is k = 0.25

y = 0.25x ← equation of proportion

when x = 64 , then

y = 0.25 × 64 = 16

By setting up the equation and solving and simplifying  the equation, the possible number of hours Frank can trim tree is 5.43 hours, round off the hour that will be 6 hours.

Algebraic simplification is the process of rewriting an algebraic expression in a simpler form, without changing its value.

An algebraic expression is a combination of numbers, variables, and arithmetic operations that can be evaluated to a specific numerical value.

let the required number of hours be h,

so setting up the equation,

7h + 9 = 47

Then we can subtract 9 from both sides to isolate h:

7h + 9 - 9 = 47 - 9

7h = 38

Dividing both sides by 7 gives us:

7h/7 = 38/7

h = 5.43

The scale factor of the transformation is 2.25

From the question, we have the following parameters that can be used in our computation:

Point H'(4.5, 6.75) is the result of dilating point H(2, 3)

This means that

The scale factor of the transformation = H'/H

Substitute the known values in the above equation, so, we have the following representation

Scale factor = (4.5, 6.75)/(2. 3)

3.  See attachment.

Step-by-step explanation:

Given information:

If the baseballs cost $4 each and x is the number of baseballs, then 4x represents the total cost of the baseballs.

The maximum amount of money available to spend on the baseballs is $25.

Therefore, the inequality to represent this is:

[tex]\large\boxed{4x \leq 25}[/tex]

Solve the inequality by dividing both sides by 4:

[tex]\implies \dfrac{4x}{4} \leq \dfrac{25}{4}[/tex]

Step-by-step explanation:

The image after a dilation by a scale factor of 4 centered at the origin is (-132,-352).

Scale factor is a mathematical term that refers to the ratio of two corresponding sides of similar shapes. It is used to compare the size of objects or figures by determining the size of a model in relation to its actual size. For example, if two shapes are similar, then their scale factor will be the same. This is useful in engineering and architecture when building scaled models of structures and machines. Scale factors can also be used to determine the proportions and measurements of an object in relation to similar objects.

This is because a dilation by a scale factor of 4 is the same as multiplying the original coordinates by 4. So, if the original coordinates were (-3,-8), then the new coordinates would be (-12,-32). Then, the coordinates are shifted by the center (the origin), so the new coordinates are (-132,-352).

1) The point of intersection is (1, 2) and (-1, 0).

2) The point of intersection is (4, 18).

3) The solutions are 0 and -2.

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

f(x) = x²(x + 1) and g(x) = x + 1

The point of intersection.

f(x) = g(x)

x²(x + 1) = (x + 1)

x² = 1

x = √1

x = ±1

x = 1, f(x) = 2.

(1, 2)

x = -1, f(x) = 0

(-1, 0)

x = 1, g(x) = 2

(1, 2)

x = -1, g(x) = 0

(-1, 0)

This means,

The point of intersection is (1, 2) and (-1, 0).

Now,

f(x) = (x + 5)(x - 2) and g(x) = (2x + 1)(x - 2).

The point of intersection:

f(x) = g(x)

(x + 5)(x - 2) = (2x + 1)(x - 2).

x + 5 = 2x + 1

5 - 1 = 2x - x

4 = x

x = 4

x = 4, f(4) = 9 x 2 = 18

x = 4, g(4) = 9 x 2 = 18

(4, 18)

The point of intersection is (4, 18).

Now,

(x - 3) (x + 5) = -15

The solutions to this equation.

x² + 5x - 3x - 15 = -15

x² + 2x - 15 + 15 = 0

x² + 2x = 0

x(x + 2) = 0

x = 0 and x + 2 = 0

x = 0 and x = -2

The solutions are 0 and -2.

Thus,

1) The point of intersection is (1, 2) and (-1, 0).

2) The point of intersection is (4, 18).

Answer: 20

Step-by-step explanation: There are 2 ways to solve this problem. This is one way, it is a shortcut. So if you didn't know, 25% of 100 (the whole thing) is 1/4, so if you divide 80 by 1/4, you should get 20. The 2nd way is to set up a proportion, so it would be 25 over 100 = ? over 80. Now, you would cross multiply the 25 and 80 to get 2000. Then you take the 2000 and divide it by 100 to get 20. I hoped this explanation helped you.

Answer:

20

Step-by-step explanation:

Write 25% as 25/100

Since, finding the fraction of a number is same as multiplying the fraction with the number, we have

25/100 of 80 = 25/100 × 80

Therefore, the answer is 20

If you are using a calculator, simply enter 25÷100×80 which will give you 20 as the answer.

The possible coordinates of point A such that the distance to point B is 10 units are:

(-5, -4) and (-5, 8)

We know that the distance between two points (a, b) and (c, d) is:

distance = √( (a - c)² + (b - d)²)

In this case, we know that:

B = (3, 2)

A = (-5, y)

And the distance is 10 units, then we can write:

10 = √( (3 + 5)² + (2 - y)²)

10² = 8² + (2 - y)²

100 - 64 =  (2 - y)²

36 =  (2 - y)²

±√36 = 2 - y

±6 = 2 - y

y = 2 ± 6

Answer:

The slope of the perpendicular line is -2.

Step-by-step explanation:

A perpendicular line has a slope that is the negative inverse of the slope of the reference line.  The reference line in this problem is 3x-6y=144.

Let's rearrange this equation to standard slope-intercept form of y=mx+b, where m is the slope and b is the y-intercept (the valuue of y when x=0).

3x-6y=144

-6y=144-3x

-6y=-3x + 144

 y = (3/6)x + (144/-6)

 y = (1/2)x - 24

This line has a slope of (1/2) and a y-intercept of -24.  A line perpendicular to this will have a slope that is the negative inverse of (1/2).  This would be -2.  The new line will take form:

 y = -2x + b

We are not given b, and there is not enough information to calculate one, so let's assume a value of -24, so that it intersects the original line at (0, -24).  See the attached graph.

Step-by-step explanation:

6*(60/15) = 1.5 (milles)

9*(60/40) = 13.5 (milles)

1.5 + 13.5 = 15 (milles)

15 / (45/60) = 20 (milles per hour)

The speed of Amy is 8.6 mph.

Speed is defined as the rate of change of distance with time. It has the dimension of distance by time. Thus, the SI unit of speed is given as the combination of the basic unit of distance and the basic unit of Time. Thus, the SI unit of speed is metre per second.

Given that, Jessica runs for 15 minutes at an average speed of 6 miles per hour. She then runs for 40 minutes at an average speed of 9 miles per hour. It takes Amy 45 minutes to run the same total distance that Jessica runs.

Calculating the distance covered by Jessica,

15 minutes = 0.25 hours

Speed = distance / time

Distance = speed × time

Distance = 0.25 × 6 = 1.5 mile

And,

40 minutes = 2/3 hours

Distance = 2/3 × 9 = 6 miles

Total distance covered by Jessica = 1.5+6 = 6.5 miles

Since, Amy covers the same distance in 45 minutes,

Therefore, 45 minutes = 3/4 hours

Speed = 6.5/0.75 = 8.6 mph

Hence, The speed of Amy is 8.6 mph.

Substituting these values into the first equation, we get:

5 = 2(1) + 1

5 = 3

This statement is not true, so (1, 5) is not a solution of this system.
