Answer:
D. 720 miles
Step-by-step explanation:
First, we know that 2.5 inches represents 300 miles. This means that we have to find out how much 1 inch represents in miles. So, we take 300/2.5. This results in 120. So, 1 inch represents 120 miles. Then, we take 6*120 which gets us 720 miles.
A map of 720 miles represented by 6 inches.
It is given that 2.5 inches represent 300 miles.
It is required to find the miles represented by 6 inches.
How many miles are represented by 6 inches?First we have to find how many miles we get in one inch. Then we find in how many miles does 6 inches have.
In 2.5 inches, the map represents 300 miles.
In 1 inch, a map represents 300/2.5 miles which are equal to 120 miles.
So, in 6 inches, a map represents (120×6) miles which are equal to 720 miles.
Thus in 6 inches, a map represents (120×6) miles which are equal to 720 miles.

Benn Cornell and Tom Ingulli drove to Chicago a distance of 510 miles, their car gets 23 miles per gallon of gasoline. gasoline costs them $2.59 per gallon. how much did they spend for gasoline on there trip?
Answer:
about $57.42
Step-by-step explanation:
we know how many miles they drove in all (510) and how many miles they can drive per gallon (23)
we need to find out how many gallons of gas they used by dividing the total number of miles they drove (510) by the number of miles per gallon (23) which is about 22.17
510 ÷ 23 = 22.17
we then need to find out how much money they spent on the total number of gallons of gas they purchased by multiplying 22.17 by the amount of money for one gallon of gas ($2.59)
22.17 × 2.59 = $57.42

Step-by-step explanation:
Sarina throws a ball up into the air, and it falls on the ground nearby. The ball's height, in feet, is modeled by the function ƒ(x) = –x2 – x + 3, where x represents time in seconds. What's the height of the ball when Sarina throws it? Question 4 options: A) 4 feet B) 1 foot C) 3 feet D) 2 feet
Answer:
(C) 3 feet
Step-by-step explanation:
We have a function of f(x) here. When Sarina throws the ball, it has been 0 seconds since she threw it.
Since x represents the amount of seconds, we can find the height of the ball (f(x)) by substituting x in as 0.
[tex]-0^2 - 0 + 3[/tex]
0 squared is 0, 0 minus zero is 0, and 0+3 = 3, so
[tex]f(x) = 3[/tex]
Meaning that when Sarina threw the ball, it's height was 3 feet.

Step-by-step explanation:
The conversion of 60 base 10 to base 2
When converting a number from base 10 to base 2, the following steps are taken:
a) The number in base 10 is divided by 2 and the remainder is recorded, this continues until the remainder is less than 2.
b) The remainder from the bottom to the top are arranged so as to get the representation of the number in base 2.
60 base 10 to base 2
60 ÷ 2 = 30 remainder 0
30 ÷ 2 = 15 remainder 0
15 ÷ 2 = 7 remainder 1
7 ÷ 2 = 3 remainder 1
3 ÷ 2 = 1 remainder 1
1 ÷ 2 = 0 remainder 1
The remainder from bottom to top is 111100 base 2.

Find a parametrization of the circle of radius 3 in the xy-plane, centered at (−2,2), oriented counterclockwise. The point (1,2) should correspond to t=0. Use t as the parameter for all of your answers.
Answer:
x = 3*cos(t) - 2
y = 3*sin(t) + 2
Step-by-step explanation:
The equation for a circle of radius 3 and centered at the point ( h , k ) ( -2 , 2 ) is:
( x - h )² + ( y - k )² = r²
In this particular case
h = - 2 k = 2 and r = 3
Then to parametrizace the equation
x = r* cos(t) + h
y = r*sin(t) + k
x = 3*cos(t) + (- 2) ⇒ x = 3*cos(t) - 2
y = 3 *sin(t) + (2) ⇒ y = 3*sin(t) + 2
Now :
when t = 0 x should be 1
Then x = 3 cos(0) - 2 x = 3 - 2 x = 1
and t = 0 y should be 2
Then y = 3*sin(t) + 2 ⇒ y = 3*sin(0) + 2 y = 2

if f(x)=4x^2-6
find all x such that f(x)= 106
Answer:
50
Step-by-step explanation:
Answer:
[tex]2\sqrt7,-2\sqrt7[/tex]
Step-by-step explanation:
So we have the function:
[tex]f(x)=4x^2-6[/tex]
And we want to find all x such that f(x) is 106. So, substitute 106 for f(x):
[tex]106=4x^2-6[/tex]
Add 6 to both sides:
[tex]112=4x^2[/tex]
Divide both sides by 4:
[tex]x^2=28[/tex]
Take the square root of both sides:
[tex]x=\pm\sqrt{28}[/tex]
Simplify the square root:
[tex]x=\pm\sqrt{28}=\pm\sqrt{4\cdot 7}=\pm2\sqrt7[/tex]
So, those are the two values that will satisfy our requirement.
And we're done!

What is a number multiplied by 12 is 84
Hey there! I'm happy to help!
Let's call our number n. Here is the information we have.
n×12=84
We want to figure out what n equals. To do this, we have to get it by itself in the equation. What we will do is cancel out the 12 by dividing both sides by 12.
n×12/12=84/12
n=7
Therefore, our number is 7.

A rectangle has a length of 12 yards less than 10 times it’s width. If the area of the rectangle is 880 yards
Answer: The length is 88 yards and the width is 10 yards. Look into the steps for more information.
Step-by-step explanation:
The length is 12 yards less than 10 times the width so we can represent that by the equation L = 10w - 12
And the area is 880 so the width times the length has to equal 880. the width is w and the length is 10w -12
w( 10w -12 ) = 880 solve for w
10w^2 - 12w = 880 subtract 880 from both sides
-880 -880
10w^2 - 12w - 880 = 0 They share the same factors so dive each side by 2
5w^2 - 6w^2 - 440 = 0
a= 5 b = -6 and c=-440
The quadratic formula says that x= -b ± [tex]\sqrt{b^2- 4ac} / 2a[/tex]
x= 6 ±[tex]\sqrt{8836} / 5[/tex]
x= 6 ± 94 /10
x= 100 /10
x = 10
In this case the width is 10 yards.
The length is 12 less than 10 times the width .
So L = 10(10) - 12
L = 100- 12
l = 88
So the length is 88
The required length and width are 229 and 27 yards.
It is required to find the dimension of rectangle.
What is rectangle?A rectangle is a type of quadrilateral, whose opposite sides are equal and parallel. It is a four-sided polygon that has four angles, equal to 90 degrees. A rectangle is a two-dimensional shape.
Given:
A=l*w
w=width
10w-12=length
According to given question we have,
6183=(10w-12)(w)
6183=10[tex]w^{2}[/tex]-14w
9[tex]w^{2}[/tex]-14w-6183=0
By simplify we get,
(9w+229)(w-27)=0
w-27=0
w=27 yards
l=9*27-14=229 yards
Therefore, the required length and width are 229 and 27 yards.
