Mary has 12 hair ribbons. 3 of the ribbons are red. What percent of her ribbons are red?

Answer:

-2

Step-by-step explanation:

the formula to find slope with two points is y2-y1/x2-x1.

for this problem it would be solved as follows:

1-3/4-3

-2/1 = -2

The slope of a line is the change in the y values over the corresponding x values.

The slope of the line that passes through (3, 4) and (4,1) is -3

Given that:

[tex](x_1,y_1) = (3,4)[/tex]

[tex](x_2,y_2) = (4,1)[/tex]

The slope (m) is calculated using:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

So, we have:

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

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

[tex]m = -3[/tex]

Hence, the slope is -3.

Answer:

x≤9

Step-by-step explanation:

9+2x≤27

1) Subtract both sides by 9:

2x≤18

2) Divide both sides by 2:

x≤9

Final answer:

Translate the verbal statement into an inequality, 9 + 2w ≤ 27, then solve for w by subtracting 9 and dividing by 2 to find w ≤ 9.

Explanation:

The statement 'Nine increased by the product of a number and 2 is less than or equal to 27' can be translated into the following inequality: 9 + 2w ≤ 27, where w represents the unknown number. To solve for w, we will follow these steps:

Subtract 9 from both sides: 2w ≤ 18.

Divide both sides by 2: w ≤ 9.

Therefore, the solution to the inequality is w being any number less than or equal to 9.

Answer:

JK=7

Step-by-step explanation:

From the line segment, since J is on it ,it means the line segment is

represented as I J K

from this illustration, we can say that the longest part of the line segment is from I to K

this means that, IJ +JK =IK

making JK the subject,

JK= IK - IJ

but from the question, JK=2x-1 , IK=3x+2 and IJ=3x-5

substituting them in the expression,

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

solving for x

2x-1 =3x+2-3x+5

2x-1 =0+7

2x-1 =7

2x=1+7

2x=8

dividing through by 2

2x/2 =8/2

x=4

but the question says we should find the numerical value for JK

but from the line segment,

JK=2x-1

but now we know the value of x to be 2

so substituting it in the formula

JK= 2(4)-1

JK=8-1

JK=7

therefore, the numerical value for JK is 7

The length of JK is found by setting the sum of IJ and JK equal to IK and solving for x. When x=4 is substituted back into the expression for JK, the calculated length of JK is 7 units.

To find the numerical length of JK, we can use the fact that IK is the entire line segment, which is the sum of IJ and JK. Therefore, we have the equation IK = IJ + JK. Substituting the given expressions, we get 3x + 2 = (3x - 5) + (2x - 1). Solving for x, we combine like terms and simplify the equation.

First, add the expressions for IJ and JK: (3x - 5) + (2x - 1) = 5x - 6.

Next, set the total length equal to the sum of parts: 3x + 2 = 5x - 6.

Now we solve for x: -2x = -8, leading to x = 4.

Finally, we substitute x back into the expression for JK to find its length: JK = 2(4) - 1 = 8 - 1 = 7.

So, the numerical length of JK is 7 units.

Answer:

Step-by-step explanation:

in discrete math, a single vertical line usually means "such that" as it relates to data sets. In this case it looks like a typo.

Answer:

5- x 6

Step-by-step explanation:

Answer: second option.

Step-by-step explanation:

We need the remember that:

[tex]\sqrt[n]{a^n}=a[/tex]

Therefore, the radicand (In this case [tex]\frac{144}{x}[/tex]) must be a perfect cube in order to get a whole number.

Remember that a perfect cube are the numbers that have exact cube roots. Therefore, "y" must be a factor of 144.

Now, we need to descompose 144 into its prime factors:

[tex]144=2*2*2*2*3*3=2^4*3^2[/tex]

Then, the factors of 144 are: [tex]1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144[/tex]

Substitute values into [tex]\frac{144}{x}[/tex] to check:

[tex]\frac{144}{1}=144[/tex]

[tex]\frac{144}{2}=72[/tex]

[tex]\frac{144}{3}=48[/tex]

[tex]\frac{144}{4}=36[/tex]

[tex]\frac{144}{6}=24[/tex]

[tex]\frac{144}{8}=18[/tex]

[tex]\frac{144}{9}=16[/tex]

[tex]\frac{144}{12}=12[/tex]

[tex]\frac{144}{16}=9[/tex]

[tex]\frac{144}{18}=8[/tex]  (Perfect cube: [tex]8=2^3[/tex])

[tex]\frac{144}{24}=6[/tex]

[tex]\frac{144}{36}=4[/tex]

[tex]\frac{144}{48}=3[/tex]

[tex]\frac{144}{72}=2[/tex]

[tex]\frac{144}{144}=1[/tex] (Perfect cube: [tex]1=1^3[/tex])

Therefore, for 2 different values of "y"  ([tex]y=18[/tex] and [tex]y=144[/tex]) [tex]\sqrt[3]{\frac{144}{y} }[/tex] is a whole number.

The length of one side of the region containing the small squares is 64 inches.

Let x be the length of one side of the region containing the small squares.

The area of the small squares is 64 * 1 = 64 square inches.

The area of the border is (x + 2)^2 - x^2 = 4x + 4 square inches.

Since the area of the small squares and the border is equal to the area of the chessboard, we have:

64 + 4x + 4 = 324

68 + 4x = 324

4x = 256

x = 64

Therefore, the length of one side of the region containing the small squares is 64 inches.

He would to jog 5 miles to go direct to his home

Step-by-step explanation:

* Lets explain how to solve the problem

- Charlie jogs 3 miles south and then 4 miles west

- We need to know if Charlie were to jog straight home, without

 changing direction how far he have to jog

- Remember: the East-west line is perpendicular to the north-south line

∵ He jogs 3 miles south

∵ He jogs 4 miles west

∵ South ⊥ west

- We can consider that the west and east distance with the straight

 distance to home formed a right triangle its legs are the south and

 west distance and the straight distance is its hypotenuse

∴ By using Pythagoras Theorem we can find the straight distance

- Remember: In Pythagoras Theorem [tex]c=\sqrt{a^{2}+b^{2}}[/tex]

 where c is the hypotenuse , a and b are the legs of the right Δ

∴ The straight distance = [tex]\sqrt{(3)^{2}+(4)^{2}}\sqrt{9+16}=\sqrt{25}=5[/tex]

Case 1:  

Consider option A

Given fractions are [tex]\frac{36}{54} \text { and } \frac{6}{9}[/tex]

[tex]\frac{36}{54}=\frac{9 \times 2 \times 2}{9 \times 2 \times 3}=\frac{2}{3} \text { and } \frac{6}{9}=\frac{2 \times 3}{3 \times 3}=\frac{2}{3}[/tex]

Hence both the fractions are equal. So they are propotional.

Case 2:

Consider option 2

Given fractions [tex]\frac{6}{7} \text { and } \frac{16}{21}[/tex] cannot be simplified further. Also both the fractions are not equal. So they are not propotional.

Case 3:

Consider option 3

Given fractions are [tex]\frac{21}{36} \text { and } \frac{21}{42}[/tex]

[tex]\frac{21}{36}=\frac{7 \times 3}{6 \times 6}=\frac{7}{12} \text { and } \frac{21}{42}=\frac{7 \times 3}{6 \times 7}=\frac{1}{2}[/tex]

Hence [tex]\frac{7}{12} \text { and } \frac{1}{2}[/tex] are not equal. Hence they are not propotional.

Case 4:

Consider option 4  

Given fractions are [tex]\frac{14}{35} \text { and } \frac{21}{42}[/tex]

[tex]\frac{14}{35}=\frac{7 \times 2}{7 \times 5}=\frac{2}{5} \text { and } \frac{21}{42}=\frac{7 \times 3}{7 \times 6}=\frac{1}{2}[/tex]

Hence [tex]\frac{2}{5} \text { and } \frac{1}{2}[/tex] are not equal. Hence they are not propotional.

6 × 10 × 10 ×10 × 10 = [tex]6 \times 10^{4}[/tex]

Step-by-step explanation:

The exponent of any number shows that how many times that number can be used in multiplication. It is the power raised to any number which show the number of times that number is raised by.

6 × 10 × 10 ×10 × 10

Here 10 is multiplied 4 times, therefore the exponent of 10 is 4.

∴ 6 × 10 × 10 ×10 × 10 = [tex]6 \times 10^{4}[/tex]

Final answer:

The expression 6X10X10X10X10 written with an exponent is 6x10⁴, indicating that 10 is multiplied by itself four times and then multiplied by 6.

Explanation:

To write 6X10X10X10X10 with an exponent, we identify the repeated multiplication of 10s. Since there are four 10s multiplied together, we use the exponent 4 to represent this, and the expression becomes 6x10⁴. This is because when you have repeated multiplication of the same number, you can express that number raised to the power of how many times it is multiplied by itself.
