Answer:
x = 4[tex]\sqrt{3}[/tex] , y = 4
Step-by-step explanation:
using the cosine and sine ratios in the right triangle and the exact values
cos30° = [tex]\frac{\sqrt{3} }{2}[/tex] , sin30° = [tex]\frac{1}{2}[/tex] , then
cos30° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{x}{8}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )
2x = 8[tex]\sqrt{3}[/tex] ( divide both sides by 2 )
x = 4[tex]\sqrt{3}[/tex]
and
sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{y}{8}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
2y = 8 ( divide both sides by 2 )
y = 4
Determine the coordinate of the point where
y=3x+6 crosses the x-axis.
Answer:
(- 2, 0 )
Step-by-step explanation:
to find where the line crosses the x- axis, let y = 0 in the equation and solve for x.
0 = 3x + 6 ( subtract 6 from both sides )
- 6 = 3x ( divide both sides by 3 )
- 2 = x
the line crosses the x- axis at (- 2, 0 )
Instead of y write 0:
0=3x+6
Now all we have to do is solve for x :0=3x+6
Subtract 6 on both sides :
-6 = 3x
Switch the order :
3x = -6
Divide by 3 on both sides :
x = -2
Now that we know the x coordinate of the point, we should find the y coordinate, which is always equal to 0.
Coordinates of the point ↓(-2, 0)
Carol, an avid hiker, typically loses 2 pounds of weight during a 3-hour hike. She always brings a Camelbak hydration pack with her, drinking 50 ounces during her hikes. How much should Carol be drinking per hour to meet her total fluid needs
The amount of water Carol should be drinking per hour to meet her total fluid needs is 16.67 ounces.
How many fluids should Carol drink hourly?Division is a mathematical operations that groups a number into equal parts using another number. The sign used to denote division is ÷.

By finding the size of each exterior angle of a regular polygon with 24 sides, calculate the size of each interior angle of the polygon.
We can find the sum of the interior angles of a regular polygon using the formula : (n-2) x 180, where n is the number of sides.
We replaced in : (24-2) x 180 = 3960
So, all the interior angles in this polygon add up to 3960.
-> Each interior angle is equal to 3960 : 24 = 165.

The surface area of a cylinder is about 155.83 square feet. The height of the cylinder is 3 times the radius. What are the height and the diameter of the cylinder, to the nearest hundredth of a foot?
The radius is approximately___ feet and the height is approximately___feet.
The diameter and height of the cylinder are 4.98ft and 7.47 feet respectively
How to calculate the surface area of a cylinderThe formula for calculating the surface area of a cylinder is expressed as:
S = 2πr(r+h)
where
r is the radius
h is the height = 3r
Substitute into the expression to have:
S = 2πr(r+3r)
S = 2πr(4r)
S = 8πr²
155.83 = 8πr²
r = 2.49feet
Since h = 3r
h = 3(2.49)
h = 7.47 feet
Hence the diameter and height of the cylinder are 4.98ft and 7.47 feet respectively

(05.01) A scale drawing of a kitchen is shown below. The scale is 1 : 20.
5 inches
4 inches
Show your work to determine the area of the room in square feet.
Answer:
500/9 or 55.56 ft²Step-by-step explanation:
Find the dimensions of the kitchen, convert to feet
5 in * 20 = 100 in = 100/12 ft = 25/3 ft4 in * 20 = 80 in = 80/12 ft = 20/3 ftThe area is
25/3 * 20/3 = 500/9 = 55.56 ft² (rounded)Answer:
5.56 ft² (nearest hundredth)
Step-by-step explanation:
Given:
width = 4 inlength = 5 inIf the scale is 1 : 20, then to scale up, multiply the width and length by 20:
⇒ width = 4 × 20 = 80 in
⇒ length = 5 × 20 = 100 in
Area = width × length
= 80 × 100
= 800 in²
1 ft = 12 in
⇒ 1 ft² = 12² in² = 144 in²
Therefore, to find the area of the room in square feet, divide the area in inches by 144:
⇒ area = 800 ÷ 144
= 5.56 ft² (nearest hundredth)
Nathan’s family spent 2 and 1/4 hours visiting national monument near their home.They watched a video in the visitor center for 1/3 of that time. how much time did they spend watching the video
Answer: 45
Step-by-step explanation: 2 1/4 = 2hr and 15 min
1/3 of 2hr and 15 min = 45
Amount of time spent by Nathan's family watching the video is 3/4 hour or 45 minutes.
What are Fractions?Fractions are numbers which are of the form a/b where a and b are real numbers. This implies that a parts of a number b.
Here, a is called the numerator and b is called the denominator.
Given that,
Nathan’s family spent 2 and 1/4 hours visiting national monument near their home.
They watched a video in the visitor center for 1/3 of that time.
Total time spent by Nathan's family in the monument = 2 + 1/4 hours
= 9/4 hours
Fraction of time spend in watching the video = 1/3
Time spend in watching the video = 1/3 × 9/4
= 3/4 hour
= 45 minutes
Hence the time spent is 3/4 hour.

Answer:
164.
Step-by-step explanation:
We can break this shape into a rectangle and a trapezoid.
Area for a rectangle is l x w, or in this case, 8 x 16.
8 x 16 = 128, so the rectangle’s area is 128.
Area for a trapezoid is ((a+b)/2)h.
We do not have all the info we need to solve this equation yet. We need the measurement of two sides of the trapezoid. This is 16 - 12, or 4. The other side of the trapezoid we need to find is 16 - 8, or 8.
Now we can plug in the numbers.
((8 + 10)/2)4
(18/2)4
9 x 4
36
Now we can add up the areas of both shapes to find the answer.
36 + 128 = 164, so the answer is 164.
Answer:164
Step-by-step explanation:
step 1: divide the irregular shape into regular shapes in this case Triangle and two rectangles
step 2: Calculate the individual areas for the shapes the area of the rectangle is (128) because the sides 16 and 8 add up to 128 as area.For the smaller rectangle the area is (32) since 8 times 4 is equal to 32 and lastly for the triangle the area is four since the base of 2 times the height of 4 equals 8 and 8 divided by two is 4 so the are of the triangle is (4)
step 3: Combine all the areas 128+32+4=64 therefore the area for the irregular figure is (164)

The mean length of 6 adults' index finger is 16.1cm.
What is the mean length (rounded to 2 DP) of these 16 people's index finger?
Get total lengths by multiplying:
10 x 12.6 = 126
6 x 16.1 = 96.6
Add the total lengths together and divide by 16:
126 + 96.6 = 222.6
222.6 / 16 = 13.9125
Rounded to 2 decimal places = 13.91
