The answer is b because the ratio is blondes to brunettes.

Follow below steps;

The student asked which statement about the proportions of blonds and brunettes among their 15 friends is false. Given that the proportion of blonds to brunettes is 6 to 9, let's evaluate the options:

Option a) The ratio of the number of friends to brunettes is 15 to 9. This statement is true since there are 15 friends in total and 9 of them are brunettes.

Option b) The ratio of brunettes to blonds is 6 to 9. This statement is false because the proportion of blonds to brunettes is 6 to 9, so the ratio of brunettes to blonds should be 9 to 6.

Option c) The ratio of blonds to the number of friends is 6 to 15. This statement is true because there are 6 blonds out of 15 friends.

Option d) The ratio of brunettes to the number of friends is 9:15. This statement is also true because there are 9 brunettes out of 15 friends.

Therefore, option b is the false statement as the ratio of brunettes to blonds is incorrectly stated as 6 to 9 instead of the correct ratio 9 to 6.

Step-by-step explanation:

$1827-$7=$11.27

$11.27/.07=161

Answer:

161 minutes

Step-by-step explanation:

Bill pays a monthly fee for his long distance phone service = $7.00

and call charges per minute = 7 cents

1 dollar = 100 cents

Therefore 7 cents = [tex]\frac{7}{100}[/tex] = $0.07

Last month, Bill's long distance bill was $18.27.

Let Bill used the phone service for x minutes

The equation for his uses in minutes :

7.00 +(0.07x) = 18.27

0.07x = 18.27 - 7.00

0.07x = 11.27

x = [tex]\frac{11.27}{0.07}[/tex]

x = 161 minutes

Bill was billed for 161 minutes.

Answer: The value of the y-intercept is [tex]-\frac{3}{5}[/tex]

Step-by-step explanation:

The equation of the line in Slope-intercept form is:

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

Where "m" is the slope and "b" is the y-intercept.

In this case we know that the line passes through point [tex](0.4,-\frac{1}{2})[/tex] and has a slope of [tex]\frac{1}{4}[/tex]. Then we can substitute the following values into  [tex]y=mx+b[/tex]:

[tex]x=0.4\\\\y=-\frac{1}{2}\\\\m=\frac{1}{4}[/tex]

Then:

[tex]-\frac{1}{2}=\frac{1}{4}(0.4)+b[/tex]

And finally, we must solve for "b":

[tex]-\frac{1}{2}=\frac{1}{4}(0.4)+b\\\\-\frac{1}{2}-\frac{1}{10}=b\\\\b=-\frac{3}{5}[/tex]

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

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

Where:

m: It's the slope

y: It is the cut point with the "y" axis

They tell us as data that:

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

So, the equation is:

[tex]y = \frac {1} {4} x + b[/tex]

We substitute the given point to find "b":

[tex]- \frac {1} {2} = \frac {1} {4} (0.4) + b\\- \frac {1} {2} = \frac {0.4} {4} + b\\b = - \frac {1} {2} - \frac {0.4} {4}\\b = -0.5-0.1\\b = -0.6[/tex]

Thus, the cut point with the y axis is -0.6

Answer:

[tex]b = -0.6[/tex]

Using the Pythagorean theorem with the length of the ladder as the hypotenuse and the base distance as one side, we calculate the height of the building to be approximately 10.82 feet.

The student's question can be solved using the principles of the Pythagorean theorem, which relates the lengths of the sides of a right triangle.

In this scenario, the ladder, the building, and the ground form a right triangle.

The ladder serves as the hypotenuse, the height of the building is the opposite side, and the distance from the ladder's base to the building is the adjacent side.

To find the height of the building, we can set up the equation using the Pythagorean theorem as follows:

a2 + b2 = c2

where a is the distance from the base of the ladder to the building (2 feet), b is the height of the building, and c is the length of the ladder (11 feet).

Plugging in the values we have:

22 + b2 = 112,4 + b2 = 121,b2 = 121 - 4,b2 = 117.

Therefore, the height of the building is:

b = √117 ≈ 10.82 feet.

The building is approximately 10.82 feet tall.

Step-by-step explanation:

however much weight the puppy gains (x) can not be greater than 25 but can be equal to 25

Answer:

[tex]15+x\leq 25[/tex]

So, [tex]x\leq 10[/tex]

Step-by-step explanation:

Boston Terriers weigh up to 25 lb.

Suppose a puppy of this breed weighs 15 pounds.

Let the puppy can weigh 'x' pounds more.

So, [tex]x=25-15=10[/tex]

But as it is given the maximum weight can be 25 pounds, so the puppy can weigh a maximum of 10 pounds more.

The diameter of the circle is approximately 20.37 cm, the radius is approximately 10.18 cm, and the length of an arc measuring 190 degrees is approximately 33.8 cm.

The subject at hand concerns the properties of a circle, more specifically its circumference, diameter, radius, and arc length.

In this case, we know that the circumference of the circle is 64 cm. The circumference of a circle is calculated by the formula 2πr (where r is the radius), or can also be viewed as πd (where d is the diameter). If we equate 64 = 2πr, we can thus find the radius, r = 64/(2π), resulting in roughly a radius of 10.18 cm. The diameter of the circle is simply twice the radius, hence in this context, it would be roughly 20.37 cm.

The length of an arc is calculated by multiplying the radius by the angle (in radian measure), which is represented as θ = s/r. In this case, the arc length is not given directly but we are given an angle of 190, and this seems to denote 190 degrees. Although it's important to mention that the standard measure for calculating arc length is radians, if we convert 190 degrees into radians, we get about 3.32 rad. Thus the length of this specific arc will be r*θ=10.18*3.32, resulting in an arc length of about 33.8 cm.

The radius of the circle with a circumference of 64 cm is approximately 10.18 cm, the diameter of the circle is 20.36 cm and the length of an arc of 190 degrees in this circle is approximately 33.78 cm.

The given circumference is 64 cm. In a circle, the circumference is given by the formula 2πr = Circumference, where r is the radius and π is a constant approximately equal to 3.14. We can rearrange this formula to find the radius: r = Circumference / 2π. Substituting the given value of the circumference, we have r = 64 cm / 2π ≈ 10.18 cm. This is the radius of the circle.

The diameter of a circle is twice the radius, hence the diameter of the circle is 2 * 10.18 cm = 20.36 cm.

Now, to find the length of an arc of 190 degrees in this circle, we first understand that the total angle in a circle is 360 degrees. Hence, the length of the arc corresponding to 190 degrees will be the ratio of 190 to 360 times the circumference. Therefore, arc length = (190/360) * 64 cm ≈ 33.78 cm.

So we have

if y=sin(ln(x)) then y=sin(u) and dy/dx=dy/du * du/dx=cos(u) *1/x

where again u=ln(x) so

dy/dx=cos(ln(x)) *1/x

Step-by-step explanation:

the demonstrated property is the commutative property

The equation a + b + 7 = 7 + b + a demonstrates the commutative property of addition, which means that the order of addition does not change the sum.

The mathematical property demonstrated by the equation a + b + 7 = 7 + b + a is the commutative property of addition. This property states that the order in which two numbers are added does not affect the sum. In other words, swapping the operands does not change the result. As shown in the equation and the principles outlined, whether you add a to b or b to a, the sum remains the same. This is true for the addition of ordinary numbers as well— you get the same result whether you add 2 + 3 or 3 + 2, for example.

Answer:

<2 = 97

Step-by-step explanation:

Definition: Supplementary angles are 2 or more angles with the same vertex that add up to 180o

Solution

<1 = 83

<2 = ?

Total = 180o

<1 + <2 = 180                   Substitute for angle 1

83 + <2 = 180                  Subtract 83 from both sides.

83 - 83 + <2 = 180 - 83   Do the subtraction

<2 = 97 degrees

The supplement of an 83-degree angle is the angle that adds up to 180 degrees with it. By subtracting 83 from 180, we find that the supplement of the angle is 97 degrees.

The question is asking for the supplement of an angle that measures 83 degrees. In geometry, the supplement of an angle is the angle that, when added to the original angle, equals 180 degrees. To find the supplement of an 83-degree angle, you subtract 83 from 180.
