A police officer investigating an accident finds a skid mark 115 feet long approximately how fast was the car traveling when the driver applied the brakes

Answers

Answer 1

The speed that describes how fast the car was traveling when the driver applied the brakes is 49 mph.

What was the speed?

The formula that is often used by police officers to determine the speed from a skid mark is this s = √21d.

So, in this case, the length or distance of the skid mark is 115 feet. We can substitute this value in the formula to get;

Speed of car = √21(115)

Speed of car = √2,415

Speed of car = 49.1426 approximately 49 mph.

So, the speed that describes how fast the car was traveling when the driver applied the brakes is 49 mph.

Step-by-step explanation:

A herd of dinosaurs made paintings in the sand with their claws. Each baby dinosaur made 1515 paintings and each adult dinosaur made 77 paintings. The entire herd made 208208 paintings in total, and there were 33 times as many baby dinosaurs as adult dinosaurs. How many baby dinosaurs and adult dinosaurs were there?

Answers

Answer:

4 adult dinosaurs and 12 baby dinosaurs.

Step-by-step explanation:

Let the number of adult dinosaurs be x.

Number of baby dinosaurs = 3x

Number of paintings made by each baby dinosaur = 15

Number of paintings made by each adult dinosaur = 7

Total number of paintings made by 3x baby dinosaurs = Number of baby dinosaurs * Number of paintings made by each baby dinosaur

= 3x * 15

= 45x

Total number of paintings made by x adult dinosaurs = Number of adult dinosaurs * Number of paintings made by each adult dinosaur

= x * 7

= 7x

Total number of paintings made by both baby and adult dinosaurs = 45x + 7x

= 52 x

Again the problem says that the total number of paintings made  = 208

So, 52x = 208

Dividing both sides by 52

[tex]\frac{52x}{52}[/tex]  = [tex]\frac{208}{52}[/tex]

Cancelling out the 52's from the top and bottom on the left

x = 4

So, number of adult dinosaurs = 4

Number of baby dinosaurs = 3x = 3*4 = 12

Final answer:

A system of equations based on the information given can be used to find the number of baby and adult dinosaurs. The two equations are 1515b + 77a = 208208 and b = 33a. Solve these to find the number of each type of dinosaur.

Explanation:

This problem can be solved by setting up a system of equations. Let's denote the number of baby dinosaurs as 'b' and the number of adult dinosaurs as 'a'. Then, from the statement, we know two things:

'Each baby dinosaur made 1515 paintings and each adult dinosaur made 77 paintings. The entire herd made 208208 paintings in total, we can set up the equation as 1515b + 77a = 208208.'There were 33 times as many baby dinosaurs as adult dinosaurs', so this can be represented as b = 33a.

By substituting the second equation into the first, we can determine the number of adult dinosaurs, and subsequently, the number of baby dinosaurs. Solving this would give us the solution needed.

Paws at play made a total of $1,234 grooming 22 dogs. Paws at play charges $43 to groom each small dog and $75 for each large dog. Write a system of equations that can be used to determine the number of small and large dogs that were groomed

Answers

Step-by-step explanation:

We are asked to write a system of equations using our given information.

Let x be number of small dogs and y be number of large dogs.

We have been given that paws at play made a total of $1,234 grooming 22 dogs, which means that number of small dogs and large dogs is 22. We can represent this information as:

[tex]x+y=22...(1)[/tex]  

We have been given that paws at play charges $43 to groom each small dog and $75 for each large dog. So the total grooming charges for grooming x small and y large dogs will be 43x+75y, that is equal to total charges for grooming $1234.

We can represent this information as:  

[tex]43x+75y=1234...(2)[/tex]

Therefore, our desired system of equations is:

[tex]x+y=22...(1)[/tex]

[tex]43x+75y=1234...(2)[/tex]

Jayda is cutting a roll of biscuit dough into slices that are 3/4 inches thick if the roll is 10 1/2 inches long how many slices can he cut?

Answers

Answer:

Jayda can cut 14 slices of dough that are 3/4 inches thick.  

Step-by-step explanation:

In order to solve this problem, we need to take the total amount of dough at 10 1/2 inches and divide it by the thickness of one slide, 3/4 inches, to find the number of slices that can be made from the total amount.  You can solve this two different ways.  You can either convert your fractions to decimals so that 10 1/2 becomes 10.5 and 3/4 become 0.75 and then divide 10.5/0.75 to get 14.  However, you can also keep them as fractions converting 10 1/2 to 21/2 and dividing by 3/4.  When we divide with fractions with keep-change-flip, or keep the first fraction-change the sign to multiplication-flip the second fraction.  So, we multiply 21/2 x 4/3 and get 84/6, or 14.

Suppose a normal distribution has a mean of 98 and a standard deviation of 6. What is P(x< or = to 110)

Answers

Answer:

97.8%

Step-by-step explanation:

110 is 2 standard deviations above the mean (6+6 = 12)

12+98 = 110

Looking at the standard deviation curve

P(x< or = to 110)  = 1 - P(x>110)

We can find the probability that x>100 by adding  anything above 2 standard deviations above the curve.

P(x>110) = 2.1+.1 = 2.2%

P(x< or = to 110)  = 1 - P(x>110)

                                = 1- 2.2%

                                = 1- .022

                                  = .978

in 2004, there were approximately 7100 cinema sites. In 2000, there were 8300.


Write an equation describing this relationship.

Answers

7100x+y =8300
so you just count the ×+y thing and boom you got it



Final answer:

The relationship between the year and the number of cinema sites can be expressed with the linear equation y = -300x + 608300, where y is the number of cinema sites and x is the year. This equation was derived by calculating the slope and y-intercept using the points provided.

Explanation:

The subject of the question falls into the domain of mathematics, specifically algebra. We are given two points on a line where the x-axis is the year and the y-axis represents the number of cinema sites. The two points are (2000, 8300) and (2004, 7100).

First, we need to calculate the slope, m: m = (y2 - y1) / (x2 - x1) = (7100 - 8300) / (2004 - 2000) = -1200 / 4 = -300.

The slope, -300, is the rate of change suggesting the number of cinemas decreases by 300 each year.

The equation of the line, or the linear equation, will be in the form y = mx + b. We now need to find the y-intercept (b) by substituting one of our points into the equation and solving for b.

If we use the point (2000, 8300): 8300 = -300*2000 + b. Solving for b gives b = 8300 + 600000 = 608300.

Therefore, the equation describing the relationship between the year and the number of cinema sites is y = -300x + 608300.

Answers

Answer:

187.69 cm

Step-by-step explanation:

We have that the maximum area allowed for the painting = 3003.04 [tex]cm^{2}[/tex].

Also, the width of Carmen's painting = 16 cm.

It is required to maximum length of Carmen's painting that will be eligible to take part in the competition.

Let the maximum length of the painting = L cm.

Since, Area of a rectangle = length of the rectangle × width of the rectangle.

i.e. 3003.04 = L × 16

i.e. [tex]L=\frac{3003.04}{16}[/tex]

i.e. L = 187.69 cm

Hence, the length of the painting should not exceed 187.69 cm in order to be eligible to participate in the competition.

We have the point

[tex]\left(-\dfrac{2}{3};\ \dfrac{\sqrt5}{3}\right)[/tex]

Substitute:

[tex]\csc\theta=\dfrac{1}{\frac{\sqrt5}{3}}=\dfrac{3}{\sqrt5}=\dfrac{3\cdot\sqrt5}{\sqrt5\cdot\sqrt5}=\boxed{\dfrac{3\sqrt5}{5}}[/tex]

The cosine of the angle is -2/3, the sine is √5/3, and the cosecant, being the reciprocal of the sine, is √5/5 after rationalization.

The point (-2/3,√5/3) on a unit circle represents the cosine and sine of a specific angle. Here, the x-coordinate is the cosine of the angle, and the y-coordinate is the sine of the angle.

Therefore, the cosine of the angle is -2/3, and the sine is √5/3.

To find the cosecant of the angle, we take the reciprocal of the sine, which gives us 3/√5 or √5/5 after rationalizing the denominator.

Answers

Final answer:

To solve a system of equations by elimination, make the coefficients of one variable equal. Subtract one equation from the other to solve for one variable, then substitute this solution into one of the original equations to solve for the other variable. In this case, the solution to the given system of equations is x = 3, y = 6.

Explanation:

In mathematics, specifically in algebra, the method of elimination is used to solve a system of simultaneous equations. Your equations are:

2x -y = 03x - 2y = -3

To solve this system by elimination, we need to make the coefficients of y in both equations equal by multiplying if necessary. We can obtain this by multiplying the first equation by 2:

4x - 2y = 0
3x - 2y = -3

Next, we subtract one equation from the other to eliminate y:

4x - 3x = 0 - (-3) => x = 3

To find y, substitute x = 3 into the first equation:

2*3 - y = 0 => y = 2*3 = 6

So, the solution to the system of equations is x = 3, y = 6.

The formula of ground speed of a airplane is given below,

[tex]v_{g} =\sqrt{}[/tex][tex](v_{a} ^{2}+v_{w} ^{2}-2v_{a} v_{w}cos\alpha)[/tex]

where, [tex]v_{g}[/tex] = Ground speed of airplane

[tex]v_{a}[/tex] = Speed of the airplane relative to the air

[tex]v_{w}[/tex] = Wind speed

[tex]\alpha[/tex] =  Internal angle

How to find the ground speed of given airplane ?

Given, [tex]v_{a}[/tex] = 160 knots, [tex]v_{w}[/tex] = 24 knots

Here, the angles increase clockwise and east is 90° heading.

The airplane is flying a heading of 90° at 160 knots speed & wind is blowing from 240° at 24 knots speed.

So, the internal angle[tex](\alpha)[/tex] = 240°-90° = 150°

Ground speed, [tex]v_{g} =\sqrt{}[/tex][tex](v_{a} ^{2}+v_{w} ^{2}-2v_{a} v_{w}cos\alpha)[/tex]

⇒ [tex]v_{g}[/tex] [tex]=\sqrt{}[/tex][tex](160^{2}+24^{2}-2*160*24*cos(150))[/tex]

5 + 10 = 15 > 14   CORRECT :)

F) 2, 10, 14

2 + 10 = 12 < 14   INCORRECT :(

Answer: B) 16, C) 10, D) 8, E) 5

Options B, C, D and E are correct answers.

Given that, a triangle has two sides of lengths 10 and 14.

We need to find what value could the length of the third side be and check all that apply.

What is the triangle inequality theorem?

Triangle inequality, in Euclidean geometry, theorem that the sum of any two sides of a triangle is greater than or equal to the third side; in symbols, a + b ≥ c. In essence, the theorem states that the shortest distance between two points is a straight line.

Now, from the given options:

A) 10, 14, 26

10 + 14 = 24 < 26 the triangle can not be formed

B) 10, 14, 16

10 + 14 = 24 > 16 the triangle can be formed

C) 10, 10, 14

10 + 10 = 20 > 14 the triangle can be formed

D) 8, 10, 14

8 + 10 = 18 > 14 the triangle can be formed

E) 5, 10, 14

5 + 10 = 15 > 14 the triangle can be formed

F) 2, 10, 14

2 + 10 = 12 < 14 the triangle can not be formed

Therefore, options B, C, D and E are correct answers.

Janie receives an allowance of \$3$3 per week. In addition, she can earn \$2$2 for each chore she does. This week, she wants to earn enough money to buy a CD for \$13$13. Janie can do fractions of chores. Write an inequality to determine the number of chores, cc, Janie must do this week to earn enough money to buy a CD.

Answers

Answer:

Number of chores done by Janie are 5.

Step-by-step explanation:

Janie's allowance per week is $3.

For each chore she earns $2.

Now we assume that number of chores in a week she does = c

Then total earning from chore = $2 × c

So for the purchase of CD total earning this week inequality will be

3 + 2c [tex]\geq[/tex]13

⇒ 2c [tex]\geq[/tex] 13-3

⇒ c [tex]\geq[/tex] 10÷2

⇒ c [tex]\geq[/tex] 5
