a race car is driving under the caution flag at 440 feet per second begins to accelerate at a constant rate after the warning flag. the distance traveled since the warning flag in feet is characterized by 30t^2+440t, where t is the time in seconds after the car starts accelerating again. How long will the car take to travel 150 feet?

Answers

Answer 1

Answer: [tex]\frac{1}{3}\ s[/tex]

Step-by-step explanation:

Given

Distance traveled is [tex]s=30t^2+440t[/tex]

for s=150 ft

[tex]\Rightarrow 30t^2+440t=150[/tex]

[tex]\Rightarrow 30t^2+440t-150=0\\\Rightarrow 3t^2+44t-15=0\\\Rightarrow (3t-1)(t+15)=0\\\Rightarrow t=\dfrac{1}{3}\ s[/tex]

Jerome discovered he had made an error when he measured one of the feathers. Which data value could be the error? Explain

Answers

Answer:

3/4

Step-by-step explanation:

From the plotted number line :

The Outlier value can be determined :

Q1 = 0.25(n+1)th term

Q1 = 0.25(21)th term =  5.25th = (2 1/4 + 2)/2 = 2.125

Q3 = 0.75(21)th term = 15.75th = 2 1/2

IQR = Q3 - Q1 = 2.5 - 2.125 = 0.375 = 3/8

Q1 - 1.5(IQR) = 2.125 - (1.5*0.375) = 1.5625

Q3 - 1.5(IQR) = 2.5 + (1.5*0.375) = 3.0625

Hence, Outlier values will be :

Values < 1.5625 and

Values > 3.0625

The Outlier value in the data is 3/4

to find the area of the rectangle, do A=lw which is 4x13=52. to find the area of the triangle, first find the height. this is 13-6=7. now do A=bh/2 which is (5x7)/2=17.5. 17.5+52=69.5 which is your answer. DONT OPEN ANY LINKS ON HERE, ITS A VIRUS
First you calculate the area of the rectangle.
It‘s simply one side times the other side.

In your task this would be:
4ft x 13ft = 52 square ft

Now you have to calculate the area of the triangle. The formula for this is: Height x Length of the base x 1/2

So in your task this would be:
7ft x 5ft x 1/2 = 17.5 square ft

(you get the 7ft by subtracting 6ft from 13ft, which results in the height of the triangle)

Now you just add those two surfaces areas together:
52 square ft + 17.5 square ft = 69.5 square ft

Answers

Area = r^2 * 3.14
87.9/3.14 = around 28
Square root of 28 = 5.3
The radius is 5.3

5.3 + 5.3 = 10.6
10.6 * 3.14 = 33.3
The circumference is 33.3

Answer:

We must be happy enough to find the value of only one valuable here, that is, x.

therefore, x-1/3=3

To find what is x-1, all we need to do is,

Take the denominator of the fraction to the answer (3)and multiply them. (that's how you'll find the values in the numerator)

So, you'll get,

x-1=3*3

x-1=9

To find the value of x,

The other number (-1) should be taken to the answer (9)

(Remember that the sign changes when the number crosses the equals sign)

therefore,

x= 9 + 1 (-1 will turn to +1 on crossing the equal sign)

Therefore , by addition, normally,

you'll get x=10

Hope this helps:)

8. The talent show committee sold a total of 530 tickets in advance. Student
tickets cost $3 each and the adult tickets cost $4 each. If the total receipts were
$1740, how many of each type of ticket were sold?

... please solve this using systems of equations

Answers

Answer:

Number of students tickets sold = x = 380 tickets

Number of adults tickets sold = y = 150 tickets

Step-by-step explanation:

Let

Number of students tickets sold = x

Number of adults tickets sold = y

x + y = 530 (1)

3x + 4y = 1740 (2)

From (1)

x = 530 - y

Substitute x = 530 - y into (2)

3x + 4y = 1740

3(530 - y) + 4y = 1740

1590 - 3y + 4y = 1740

- 3y + 4y = 1740 - 1590

y = 150

Substitute y = 150 into (1)

x + y = 530

x + 150 = 530

x = 530 - 150

x = 380

Number of students tickets sold = x = 380 tickets

Number of adults tickets sold = y = 150 tickets

Which transformation(s) can map TriangleMNQ onto TrianglePQN?

rotation, then reflection
rotation, then translation

Answers

Answer:

rotation, then translation

Step-by-step explanation:

The transformation that map triangle MNQ onto triangle PQN is rotation, then translation.

The given triangles;

Triangle MNQ Triangle PQN

A translation of a triangle occurs when the triangle shifts up, or down,  of left or right on the coordinate plane.

The reflection of a triangle occurs when the vertices of the triangle is flipped over the opposite side.

Since the triangle MNQ is rotated then shifted to the left to form the new triangle PQN, we can conclude that the transformation that map triangle MNQ onto triangle PQN is rotation, then translation.

Answers

Selling price = $100

% markup = (selling-cost/cost)*100

% markup = (100-75/75)*100

% markup = (25/75)*100

% markup = (0.33333333333)*100
