Max Steel drives his 1969 Mustang 15 miles per hour. If there are 5280 feet in one mile and 60 seconds in one minute, how many feet can he go per second?
Answer:
22 feet per second
Step-by-step explanation
15x5280=79,200
79,200/60=1320 feet per minute since 60 minutes per hour
1320/60=22 feet per second since 60 seconds per minute
Max Steel's Mustang can go upto 22 feet per second.
First, convert miles per hour to feet per hour. Since there are 5280 feet in a mile, multiply the speed in miles by the number of feet in a mile:
Step 1: 15 miles/hour x 5280 feet/mile = 79200 feet/hour
Step 2:Next, convert feet per hour to feet per minute. Since there are 60 minutes in an hour, divide by 60:
79200 feet/hour ÷ 60 = 1320 feet/minute
Step 3: Finally, convert feet per minute to feet per second. Since there are 60 seconds in a minute, divide by 60:
1320 feet/minute ÷ 60 = 22 feet/second
Therefore, Max Steel can go 22 feet per second.

One more than three-eighths of a number is eleven. Just write out equation do not solve please
Answer:
Let's just call the number x. 3/8ths of x and 1 more equals 11.
As an equation, this basically means
[tex]\frac{3}{8} x+1=11[/tex]
The equation derived from the given statement "One more than three-eighths of a number is eleven" is 3/8 * X + 1 = 11.
Explanation:In mathematics, especially in algebra, we often have to deal with problems where a certain relationship is given between a number and its fraction, and the task is to find the number. In the problem you presented, "One more than three-eighths of a number is eleven", we are required to express this problem as an equation.
The three-eighths of a number can be represented as 3/8 * X (where X is the unknown number we're seeking), and 'one more than' simply means we're adding 1 to this fraction. The given relationship states that this result is eleven.
So, the equation can be written as: 3/8 * X + 1 = 11.

find the volume of the cylinder. round your answer to the nearest tenth.
Answer:
1526.8 cubic feet.
Step-by-step explanation:
Volume for finding any shape is V= Bh where b is the area of he base multiplied by the height of the shape. Find the area of the circle, which is pi times the radius squared 9 times 9 is 81. Multiply 81 by pi or 3.14159265 is 254. 4690047. Then, multiply that number 6 which is the height of your shape, and you get 1526.814028. Rounded to the nearest tenth is 1526. 8 cubic feet. Hope this helps!
The Volume of Cylinder is 1,526.04 ft².
What is Volume?Volume is a three-dimensional measurement that's used to gauge a solid shape's capacity. It implies that the volume of a closed form determines how much space it can occupy in three dimensions.
As, the Volume of Cylinder = πr²h where r is the radius and h is the height.
Given:
Radius of cylinder = 9 feet
Height of cylinder = 6 feet
So, Volume of Cylinder
= πr²h
= 3.14 x 9 x 9 x 6
= 3.14 x 81 x 6
= 1,526.04 ft²
Thus, the volume is 1,526.04 ft².

the discriminant of x2 + 6x + 9 = 0
Answer:
D = 0
Step-by-step explanation:
D = b^2 - 4ac =
= 6^2 - (4*1*9) =
= 36 - 36 = 0
Final answer:
The discriminant of the quadratic equation x² + 6x + 9 = 0 is 0, which means there is one real root, and the graph of the equation is tangent to the x-axis at one point.
Explanation:
The discriminant of a quadratic equation is the part of the formula b² - 4ac that determines the nature of the roots of the equation. For the quadratic equation x² + 6x + 9 = 0, we can identify a = 1, b = 6, and c = 9. Using the discriminant formula, we get:
• Discriminant, D = b² - 4ac
• D = (6)² - 4(1)(9)
• D = 36 - 36
• D = 0
Since the discriminant is zero, it indicates that the quadratic equation has one real root, and the graph of the equation touches the x-axis at one point (the vertex of the parabola).

MATH EASY POINTS: the volume of water y (in cubic meters) that flows over niagara falls during peak daytime tourist hours in x minutes can be approximated by the equation y=168,000x. Approximately how many cubic meters of water flow over the falls in one hour
Answer:
10,080,000 cubic meters is the answer.
Step-by-step explanation:
For every minute (x), 168,000 cubic meters (y) of water are added. 1 hour has 60 minutes, so 60 x 168,000. That gives 10,080,000.

What is F x and G x?Composition of a function is done by substituting one function into another function. For example, f [g (x)] is the composite function of f (x) and g (x).

What is the sum of G x and f x?Suppose we have two functions, f(x) and g(x). We can define the sum of these two functions by, (f + g)(x) = f(x) + g(x), where x is in the domain of both f and g.

You are measuring the height of a lamppost. You stand 40 inches from the base
of the lamppost. You measure the angle of elevation from the ground to the top!
of the lamppost to be 70°. Find the height h of the lamppost to the nearest inch.
Answer:
110in
Step-by-step explanation:
The horizontal distance from where you stand to the lamp post is 40 inches.
Let the height of the lamp post be y inches.
The angle of elevation from the ground to the top!
of the lamppost to be 70°.
The height , y and the horizontal distance, form the legs of a right triangle .
We can use the tangent ratio, to calculate the height of the lamp post .
[tex] \tan(70 \degree) = \frac{y}{40} [/tex]
[tex]y = 40 \tan(70) [/tex]
[tex]y = 109.9[/tex]
To the nearest inch, the height is 110 inches
The height of the lamppost is approximately 110 inches, calculated using the tangent of a 70° angle with a base distance of 40 inches.
To find the height ( h ) of the lamppost, we can use trigonometric relationships. Given that we stand 40 inches from the base of the lamppost and measure the angle of elevation to be 70°, we can use the tangent function:
[tex]\[\tan(\theta) = \frac{\text{opposite}}{\text{adjacent}}\][/tex]
In this scenario:
- The angle [tex]\(\theta = 70^\circ\)[/tex]
- The adjacent side (distance from the base) is 40 inches
- The opposite side is the height \( h \) of the lamppost
Using the tangent function, we have:
[tex]\[\tan(70^\circ) = \frac{h}{40}\][/tex]
To solve for ( h ), we rearrange the equation:
[tex]\[h = 40 \cdot \tan(70^\circ)\][/tex]
Now we need to calculate [tex]\( \tan(70^\circ) \):[/tex]
[tex]\[\tan(70^\circ) \approx 2.747\][/tex]
Multiplying this by 40 inches:
[tex]\[h = 40 \cdot 2.747 \approx 109.88\][/tex]
Rounding to the nearest inch:
[tex]\[h \approx 110 \text{ inches}\][/tex]
Therefore, the height of the lamppost is approximately 110 inches.

The perimeter of a rectangular shop in the mall is 34 m the area is 70 m² what are the dimensions of the shop
Answer:7 x 10
1) Can be done by trail and error
Or
2) setting and slowing two equations
Step-by-step explanation:
If a and b are sides of rectangle
(1). 2a + 2b = 34
(2). ab = 70
From 1
a= 17-b
Substitute above a to (2)
(17-b)b = 70
17b - b^2 = 70
-b^2 + 17b -70 = 0
Multiple above by -1
b^2 - 17b + 70 = 0
Solving quadratic equation by factorising
(b-7)(b-10)=0
b=7 or b=10
If b= 7. a =10
If b=10. a=7
The dimensions of the rectangular shop that satisfies the given condition of having a perimeter of 34 m and an area of 70 m² are length=20 m and width=7 m.
Explanation:The question is about finding the dimensions of a rectangular shop, given its perimeter and area. The perimeter and area of a rectangle can be expressed using the formulas Perimeter = 2*(length + width) and Area = length * width. In the problem, we are given that the perimeter is 34 m and the area is 70 m².
Let's denote the length as 'l', and the width as 'w'. To solve this, we can setup and solve a system of equations based on our formulas:
2*(l + w) = 34
l * w = 70
From these equations we can find that the dimensions of the rectangular shop that fit the conditions are length=20 m and width=7 m.

Angles A and B are two acute angles in a triangle. If sin A equals cosine B, what can you conclude about the triangle?
Answer:
It's a right angle triangle with 90° at C
Step-by-step explanation:
sin A = cosB when
A + B = 90
The condition that sin A equals cosine B, with A and B being acute angles, indicates that both angles are complementary and add up to 90 degrees, suggesting a right-angled triangle.
Explanation:When given the condition that sin A equals cosine B in a triangle, and both angles A and B are acute, we can determine that triangle A and B are complementary, which means they add up to 90 degrees.
This is due to the co-function identity, where sin(90° - θ) = cos(θ) and cos(90° - θ) = sin(θ) for acute angles in right-angled triangles.
If A and B are in the same triangle, and given it is a right triangle (since they are acute and the sine of one equals the cosine of the other), we can conclude that A + B = 90°, and thus, the third angle will also be 90 degrees, making the triangle a right-angled one.
