Answer: 244.95 feet
Step-by-step explanation:
This scenario forms the shape of a right angled triangle with the shadow length being the triangle's length and the distance between the end of the shadow to the top of the building being the hypotenuse.
Use Pythagorean theorem:
c² = a² + b²
250² = 50² + b²
62,500 = 2,500 + b²
b²= 62,500 - 2,500
b² = 60,000
b = √60,000
b= 244.95 feet

is 0.09kg greater than 6g
Answer:
Yes
Step-by-step explanation:
0.09kg = 90g
90g > 6g
Hi there!
yes..
1.Find how much is 0.01kg:
[tex]0.01=10[/tex]
Now we know that 0.09 is in fact greater than 6g..
2.Multiply it by 0.09:
[tex]10[/tex]·[tex]9=90[/tex]
Therefore, 0.09kg is greater 6g..
0.09kg>6g

Write an equation using slope intercept form when m=4 and b=12
Answer:
y = 4x + 12
Step-by-step explanation:
slope-intercept form is y = mx + b, where m = slope and b = y-intercept.
since you're given the values for m and b, all you need to do is plug those into the equation for slope-intercept form.
plug in 4 for m.
y = mx + b ⇒ y = 4x + b
plug in 12 for b.
y = 4x + b ⇒ y = 4x + 12
it doesn't matter which one you plug in first as long as you plug the value in for the correct variable.
the equation of your line in slope-intercept form is y = 4x + 12. i hope this helps! have a great day <3

Write a multiplication equation that represents the question: how many 38s are in 54?
Answer:
The answer is 3 1/3.
Step-by-step explanation:
To find this answer, divide 5/4 by 3/8.
(5/4) / (3/8) = 5/4 * 8/3 = 40/12 = 10/3 or 3 and 1/3.
Proof:
10/3 * 3/8 = 30/24 = 5/4
If 5x-2=23, then find the value of x
Answer:
x = 5
Step-by-step explanation:
5x = 2 + 23
5x = 25
x = 5

En un triángulo obtusángulo, uno de los ángulos mide 20° mas que el otro. El tercer ángulo, mide el doble que el mayor de los dos que hemos citado. ¿?Cuánto miden los ángulos de dicho triángulo
Answer:
La medida del primer ángulo es 30°, la medida del segundo ángulo es 50° y el tercer ángulo mide 100°.
Step-by-step explanation:
Siendo "x" el valor de un ángulo del triángulo obtusángulo, sabes que uno de los ángulos, llamado segundo ángulo, mide 20° más que el primero. Este segundo ángulo se representa como x + 20°.
Además, un tercer ángulo mide el doble que el mayor de los dos, que en este caso es el ángulo cuya expresión es x + 20°. Por lo que el doble de este será 2*(x + 20)°, que será la medida del tercer ángulo.
Teniendo en cuenta que la suma de los ángulos interiores de un triángulo es 180°. Entonces, es posible sumar los valores de cada uno de los ángulos e igualarlos a 180°:
x + x + 20° + 2*(x + 20°) = 180°
Resolviendo:
x + x + 20° + 2*x + 2*20° = 180°
x + x + 20° + 2*x + 40° = 180°
4*x + 20° + 40° = 180°
4*x + 60° = 180°
4*x = 180° - 60°
4*x = 120°
x = 120° ÷ 4
x = 30°
Entonces, la medida del primer ángulo es 30°. El segundo ángulo es calculado como x + 20° = 30° + 20° = 50° mientras que el tercer ángulo es 2*(x + 20°) = 2*(30° + 20°) = 2*(50°) = 100°
La medida del primer ángulo es 30°, la medida del segundo ángulo es 50° y el tercer ángulo mide 100°.

Ok need help this is the question :Use the Pythagorean theorem to write an equation for the distance Jane's trainer bikes.
Answer:
Jane traveled 8 miles farther then her trainer
Step-by-step explanation:
The Pythagora's Theorem
In any right triangle, the square of the measure of the hypotenuse is the sum of the squares of the legs. This can be expressed with the formula:
[tex]c^2=a^2+b^2[/tex]
Where
c = Hypotenuse or largest side
a,b = Legs or shorter sides
Jane's path from the Health Club to the end of her route describes two sides of a right triangle of lengths a=16 miles and b=12 miles.
Her total distance traveled is 16 + 12 = 28 miles
Her trainer goes directly from the Health Club to meet her through the hypotenuse of the triangle formed in the path.
We can calculate the length of his route as:
[tex]c=\sqrt{16^2+12^2}[/tex]
[tex]c=\sqrt{256+144}=\sqrt{400}=20[/tex]
c = 20 miles
The difference between their traveled lengths is 28 - 20 = 8 miles
Jane traveled 8 miles farther then her trainer
Are any of these trees an outlier?

2. Which of the following is the correct interpretation of confidence interval? (circle one)
a. If the same experimental process is done on many samples, with a given percentage certainty,
the population parameter will fall within a calculated range.
b. When many different processes are done on the same sample, with a given percentage certainty,
the population parameter will fall within a calculated range.
c. If the same experimental process is done on many samples, with a given percentage certainty,
each sample will determine its own calculated range with a given percentage certainty
3. In a certain study, a population parameter is predicted to be in the interval (42, 60) at a 95% confidence
level. What is a reasonable confidence interval if the confidence level is adjusted to 98%

If f(x) = 3x - 15, what is f(4)?
A. 3
B. -3
c. 12
D. -8
Answer:
B. -3
Step-by-step explanation:
f(x) = 3x - 15
f(4) means x=4, so you want to plug 4 into the equation.
f(4) = 3(4) - 15
f(4) = 12 - 15
f(4) = -3
Answer:
B
Step-by-step explanation:
f(4) has the same meaning (for this question ) as x = 4
Let x = 4
f(4) = 3*4 - 15
f(4) = 12 - 15
f(4) = - 3
B
