Answer:
1. 466.3ft
2. 12.1m
Step-by-step explanation:
1.
Imagine this as a triangle like shown in pic attached, then use tan to find 'x', the distance between the base of the tower and the fire:
tanA=opposite/adjacent
tan25=x/1000
x=100tan25
x=466.3ft
2.
Imagine this as a triangle like shown in pic attached, then use sine to find 'x', the kite's vertical height above the boy's hand:
sinA=opposite/hypotenuse
sin12=x/50
x=50sin12
x=10.4m
The kite's height off the ground is this plus the height of the boy's hand from the ground: 10.4+1.7=12.1m

While traveling to his grandmother's house for Christmas, George fell asleep halfway through the journey. When he awoke, he still had to travel half the distance that he had traveled while sleeping. For what part of the entire journey did he sleep?
he slept for 1/2 of the trip and then slept have the distance that was left so that would be 1/2 divided by 2 equals 1/4 so 1/2 plus 1/4 equals 3/4 so george has 1/4 of his journey left.
George was asleep for 33.3% of the journey.
When George went to sleep, he was halfway through to his grandmother's house which means that he was left with 1/2 of the journey.
When he woke up, he was still left with half of the distance he had slept. If we made this an expression and assume the percentage of the journey he slept was x, it would be:
1/2 of the journey = 1/2x + x
1/2 = 1.5x
x = 1/2 ÷ 1.5
x = 33.3%
George therefore fell asleep for 33% of the journey.

Which of the following are solutions to the following equation?
4x^2-100=0.
Check all that apply.
A. 5
B. -10
C. -5
D. 10
Answer:x=5 or x=−5
Step-by-step explanation:
4x^2−100=0
Step 1: Add 100 to both sides.
4x^2−100+100=0+100
4x^2=100
Step 2: Divide both sides by 4.
4x^2/4=100/4
x^2=25
Step 3: Take square root.
x=±√25
x=5 or x=−5
Answer:
x=5 or x=−5
Hey i need help with this
Answer:
The x-intercepts are 1 and 3
The y-intercept is 3
The vertex is (2,-1)
The line of symmetry is x=2
Step-by-step explanation:
To find the x-intercepts, find where the graph intersects the x-axis, or the horizontal line. To find the y-intercept, find where the graph intersects the y-axis, or the vertical line. To find the vertex, find the coordinate where the graph is at its lowest point (or highest if it is flipped upside down). To find the line of symmetry, simple use the x-coordinate of the vertex and say x= (the x-coordinate)

Part A: Determine the unit rate for the amount of one T-shirt. Explain how you determined the unit rate.
9514 1404 393
Answer:
$15
Step-by-step explanation:
The desired rate is ...
"unit rate" = cost/T-shirt = $180/(12 T-shirts) = $15/T-shirt
__
The unit rate is based on its definition. Here, the rate of interest is the cost per shirt, so it is found by dividing the cost by the number of shirts.

Find the coordinates of the vertex of the following parabola algebraically. Write your
answer as an (x, y) point.
y = 4x + 56x + 192
Answer:
The vertex of the parabola = (-7 , -4)
Step-by-step explanation:
Step(i):-
Given that the parabola y = 4 x² + 56 x +192
y = 4 (x² + 14 x + 48 )
y = 4 ( x² + 2 × 7 (x) + 49-1)
y = 4 ( x² + 2 × 7 (x) + 49)- 4
we apply the formula
(a +b)² = a² + 2ab + b²
y = 4 ( x + 7 )² - 4
Step(ii):-
The general form of the parabola in algebraically
y = a ( x-h)² +k
The equation
y = 4 ( x + 7 )² - 4
y = 4 ( x-(-7))² - 4
The vertex of the parabola (h,k) = (-7 , -4)
Final answer:-
The vertex of the parabola = (-7 , -4)
A ball is dropped from the top of a building that is 250 feet tall. The
height h of the ball in feet after t seconds is modeled by the function h =
- 16t2 + 250. How long will it take for the ball to reach a height of 75
feet? Round to the nearest tenth.
hi
-16t²+250 = 75
-16t² = 75 -250
-16t² = -175
t² = -175 /-16
t² = 175/16
Here there si two solutions : t = [tex]\sqrt{175/16}[/tex] and t = - [tex]\sqrt{175/16}[/tex]
However, as time cannot rewind, we will keep only positive solution
So t = [tex]\sqrt{175/16}[/tex]
in seconds it will be : 3.3 seconds

In a sale the normal price of a book is reduced by 30% what singles number must be i multiple by to reduce something by 30%
I need help
Step-by-step explanation:
This means the price of the book will decrease by 100%-30%=70%
70% decrease in x = 100% of x - 70% of x = 1x - 0.7x = (1 - 0.7)x = 0.3x So 0.3x represents a 70% decrease in x.
Notice that this multiplier .3 is the same as (30% of x).
the answer is 0.3.

Maria noticed that a fork in the road created 3 angles. If two angles are as shown, what is the measure of angle x?
А
135°
00
140°
с
145°
D
150°
The measure of angle x will be 145° so option (C) will be correct.
What is an angle?
An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.
Since we lack a measurement for angular rotation, the angle is a valuable tool for measuring angular distance. For instance, a meter or an inch is a unit of measurement for linear motion.
The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.
The angle all around the line is 360°.
The angle 165°, 50°, and x consist total of 360°.
165 + 50 + x = 360
x = 145°.
So the angle of x will be 145°.
