Step-by-step explanation:

First you would change 2/3 to 4/6

Ignore the part where he took a break. This isn't about time its distance.

Then you would add 4/6 and 5/6 and end with 1  1/2

Last you subtract 1/2 from 1  1/2 and you get the answer of 1

Answer:

The slope is  -14/11

Step-by-step explanation:

To find the slope, use the formula

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

   = (8--6)/ (-1-10)

   = (8+6)/(-1-10)

   = 14/-11

  = -14/11

Answer:

3 miles per hour

Step-by-step explanation:

We need to subtract the two numbers to find the difference in speeds

4/5 - 3/4

We need to get a common denominator of 20

4/5 *4/4 - 3/4 *5/5

16/20 - 15/20

1/20  

The car going 4/5 miles per minute is going 1/20 miles per minute faster than the car going 3/4 miles per minute.

The question asks for miles per hour, not miles per minute.  We know  that there are 60 minutes per hour.

1/20 miles per minute * 60 minutes / hour

60/20 miles/hour

3 miles/ hour

The car going 4/5 miles per minute is going 3 miles per hour faster than the car going 3/4 miles per minute.

Answer:

770

Step-by-step explanation:

3.5 x 220 = 770

770/3.5 = 220

770/220 = 3.5

To find what 3.5 multiplied by 220 is, you simply multiply the two numbers together to get 770. This can be related to weight calculations in personal training contexts.

This question demands basic understanding of mathematical operations (addition, subtraction, multiplication, division) in general and about multiplication in particular.

The question What's 3.5 x 220? is asking for the product of the two numbers, 3.5 and 220, which is a mathematics calculation. To find the answer, you multiply 3.5 by 220, which equals 770.

Another way is to find 350% of 220 which means 350/100 * 220 = 770

This calculation is relevant for the student's personal training classes, potentially relating to the amount of weight lifted or the calculation of potential energy.

Therefore, as per the above explaination, the correct answer is 770.

Step-by-step explanation:

The square root of 101 lies between 10 and 11, as 101 falls between the perfect squares of these two numbers (100 and 121, respectively).

The square root of 101 is a value which, when multiplied by itself, results in 101. In order to find which two consecutive numbers this square root lies between, we need to consider which two perfect squares it falls between. The perfect squares closest to 101 are 100 (which is 10^2) and 121 (which is 11^2). Therefore, the square root of 101 lies between the numbers 10 and 11.

Step-by-step explanation:

Let's get an important definition out of the way first. A parallelogram is a quadrilateral with two pairs of parallel sides. We can translate this idea to coordinate geometry by saying that each pair of opposite sides must have the same slope.

Slope, as you might remember, is a measure of change. Specifically, it's the change in a line's y value (Δy) divided by the corresponding change in its x value (Δx). This means that if we can prove that:

We'll have proved our figure is a quadrilateral. Let's prove those cases, then. For KA and IT:

[tex]slope_{KA}\stackrel{?}{=}slope_{IT}[/tex]

To find the slope of any line segment, we can find the difference between the corresponding coordinates of its endpoints and divide the difference in y-coordinates by the difference in x-coordinates. Since the endpoints of KA are K(0, 0) and A(a, 0), the slope of these points is

[tex]slope_{KA}=\frac{0-0}{a-0} =\frac{0}{a} =0[/tex]

We can do this same for IT using its endpoints I(a + b, c) and T(b, c):

[tex]slope_{IT}=\frac{c-c}{b-(a+b)} =\frac{0}{-a}=0[/tex]

Since 0 = 0, we can say that [tex]slope_{KA}=slope_{IT}[/tex], and we've proven our first condition. Now we just need to prove that [tex]slope_{KT}=slope_{AI}[/tex]:

[tex]slope_{KT}\stackrel{?}{=}slope_{AI}[/tex]

Using K(0, 0) and T(b, c), [tex]slope_{KT}=\frac{c-0}{b-0}=\frac{c}{b}[/tex], and using A(a, 0) and I(a + b, c), [tex]slope_{AI}=\frac{c-0}{(a+b)-a}=\frac{c}{b}[/tex], proving that [tex]slope_{KT}=slope_{AI}[/tex].

Since we've proven that [tex]slope_{KA}=slope_{IT}[/tex] and [tex]slope_{KT}=slope_{AI}[/tex], we've proven that the quadrilateral KAIT is, by definition, a parallelogram.

Answer:

2.  Circumcenter is (-2, 1)

4.  Orthocenter is (5, 0)

6. II ∠DOS and ∠CAT are vertical and III ∠DOS and ∠CAT are adjacent

8.  m∠PBC = 30°

10.  KV, VM, KM

12.  DC is greater

14.  x = 12

Step-by-step explanation:

2.  Equation of the perpendicular bisector of AB is x = -2 and the equation of the perpendicular bisector of BC is y = 1.

Circumcenter is the point of intersection of the perpendicular bisectors of the sides of the triangle.

Hence, circumcentre is (-2, 1).

4.  Orthocenter is the point of intersection of the altitudes. Here, AB and BC are two altitudes and B is their point of intersection.

Hence, the orthocenter is (5, 0).

6.  Adjacent angles are angles separated by a line and vertical angles are angles vertically opposite to each other.

Hence, statements II and III contradict to each other.

8.  If P is equidistant from all the three sides, then P is the center of the in-circle and hence it is the incenter of the triangle.

If P is the incentre, then PB is the internal bisector.

Therefore, ∠PBC = [tex]\frac{1}{2}[/tex] ∠ABC = 30°

10.  From the triangle sum property, ∠ M = 180 - (110 + 40) = 30.

Since, the side opposite to the smallest is the shortest, the correct order is:

KV, VM, KM

12.  Clearly, ∠ ABD is acute. Therefore, ∠ DBC > ∠ ABD.

Since, side opposite to larger angle is greater, DC is greater.

14.  Let the sides of the top triangle be p and q. So, two sides of whole triangle are 2p and 2q.

Now, if we compare the top small triangle and the whole triangle, they are similar by SAS similarity since,

the top angle is common and [tex]\frac{p}{2p}=\frac{q}{2q}=\frac{1}{2}[/tex].

Since, corresponding parts of similar triangles are proportionate,

[tex]\frac{3x}{5x+12} =\frac{1}{2}[/tex]

6x = 5x + 12

6x - 5x = 12

x = 12

Answer:

Correct choice is D

Step-by-step explanation:

The graph of the function shows that the function is not continuous at point x=3.

When moving to the point x=3 from the left side, you can see that y approaches to -1. When moving to the point x=3 from the right side, then y approaches to -3 and at x=3, y=7. This gives you that the limit doesn't exist.

Answer:

The right option is A) 0.72%

Step-by-step explanation:

We have given,

Number of shares = $100

Park stock per share = $52.89

Total parks stock = 100×52.89 = $5289

Since company paid annual dividends of $0.38 per share.

Total annual dividend company paid = 100×0.38 =$38

Total annual yield in % = [tex]\frac{38}{5289} *100[/tex] = 0.718 % ≈0.72%

To find the height of the ramp at its highest point, we can use trigonometry and the sine function.

To find the height of the ramp at its highest point, we need to determine the vertical component of the ramp. We can use trigonometry to do this. Assuming the ramp forms a right triangle with the ground, we can use the sine function to calculate the height:

height = ramp length * sin(angle)

Given that the ramp length is 24.5 feet and the angle is not provided, we cannot calculate the exact height without that information. Please provide the angle, and I'll be happy to help you find the height.

Answer:

Batman's equation of this scenario is not accurate.

Step-by-step explanation:

The exponential function representing this situation should be

[tex]y=a\cdot b^{nx},[/tex]

where a is the initial amount of  baddies living at Arkham asylum, b is the rate at which enemies increased, n is the number determing the period of enemies increasing and x is time in years.

In your case,

a=4 (initially there were 4 baddies living at Arkham asylum),

b=2 (the population doubled),

n=1/2 (the population doubled every 2 years).

Then

[tex]y=4\cdot 2^{\frac{x}{2}}.[/tex]

Note then when considering the function [tex]y=4\cdot 2^x[/tex] the population dubled each year, not every 2 years.

Batman's equation y=4(2)ˣ correctly models the doubling population of bad guys every 2 years. It uses an exponential growth formula that accurately calculates the population for any given 2-year period.

Yes, Batman's equation y=4(2)ˣ accurately represents the scenario of the population of bad guys doubling every 2 years. The equation follows an exponential growth model, where the initial population is 4, and it doubles with each increment of x, representing a 2-year interval. Therefore, for any given value of x (the number of 2-year intervals since the initial count), the equation will yield the correct population size.

To further illustrate, after the first 2-year interval (x=1), the population would be y=4(2)¹=8, which is double the initial population. After the second 2-year interval (x=2), the population would be y=4(2)²=16, continuing the pattern of doubling.

Width: 5 + 2x

Note that you have to add x at each end of the picture and onto each part of the width.

The entire area is 120 square inches.

Formula

L*W = Area

(2x + 7)(2x + 5) = 120

Solution

4x^2 + 10x + 14x + 35 = 120                Subtract 120 from both sides. Add xs

4x^2 + 24x + 35 - 120 = 0

4x^2 + 24x - 85 = 0                             Factor

(2x + 17)(2x - 5)

2x + 17 has no meaning. It will give -  8.5 which is not possible.

Question

Find 1/8 of 12. Express your answer in simplest form.

1 1/2

2/3

1/96

12/8

Answer:

Step-by-step explanation:

12 : 8 = 1.5 (1 1/2)

To find 1/8 of 12, multiply 12 by 1/8 and simplify the fraction to its simplest form, which is 3/2.

To find 1/8 of 12, we can multiply 12 by 1/8. Multiplying fractions is done by multiplying the numerators together and multiplying the denominators together. In this case, 12 multiplied by 1 equals 12, and 8 multiplied by 1 equals 8, so the answer is 12/8.

However, 12/8 is not in simplest form because the numerator and denominator have a common factor of 4. To simplify the fraction, we divide both the numerator and denominator by 4. 12 divided by 4 is 3, and 8 divided by 4 is 2. So, the simplest form of 12/8 is 3/2.
