5. A raincloud contains 2500 litres of water. The cloud is decreasing in size at
a rate of 4.3% per hour. Calculate the volume of water in the cloud in 8
hours time.
Answer:
Volume 1758.88 litres
Step-by-step explanation:
[tex]P = 2500. \ r = 4.3\% = \frac{4.3}{100} = 0.043, t = 8\\\\Volume = P(1 - r)^t\\\\[/tex]
[tex]= 2500(1-0.043)^8\\\\= 2500 \times 0.70355\\\\= 1758.88 \ litres[/tex]

Question : find the measure of angles x and y
show your work and write a sentence staring the answer
Answer:
x = 53°, y = 42°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 given angles from 180° for x
x = 180° - (37 + 90)° = 180° - 127° = 53°
48° + y = 90° ( subtract 48° from both sides )
y = 42°

sin =9/15 . Find tan 0
Answer:
c. 9/12
Step by step explanation.
Given: sin = 9/15
and,
[tex]sin = \frac{opp.}{hyp.} [/tex]
[tex]tan = \frac{opp.}{adj.} [/tex]
thus, find adj. side
by using Pythagoras theorem
[tex] {c }^{2} = {a}^{2} + {b}^{2} [/tex]
then,
let adj. side be a^
[tex] {a}^{2} = {c}^{2} - {b }^{2} \\ {a}^{2} = {15 }^{2} - {9}^{2} \\ {a}^{2} = 144 \\ a = 12[/tex]
thus,
adj. side is 12
then,
tan of the angle = 9/12

using the triangle 45o -45o -90o theorem solve this triangle. please
Answer:
The length of the leg is 11 units.
Step-by-step explanation:
The triangle 45 - 45 - 90 theorem states that the length of the hypotenuse is [tex]\sqrt{2}[/tex] times of the length of any of the legs. Hence, we get the following expression:
[tex]h = \sqrt{2} \cdot l[/tex] (1)
Where:
[tex]l[/tex] - Length of the leg, in units.
[tex]h[/tex] - Hypotenuse, in units.
If we know that [tex]h = 11\sqrt{2}[/tex], then the length of the leg is:
[tex]l = \frac{h}{\sqrt{2}}[/tex]
[tex]l = 11[/tex]
The length of the leg is 11 units.

Solve 5x + 17 = 4(3x - 1) x = -3 x = -3 Infinitely many solutions Infinitely many solutions No solutions No solutions x = 3
Answer:
3 =x
Step-by-step explanation:
5x + 17 = 4(3x - 1)
Distribute
5x+17 = 12x -4
Subtract 5x from each side
5x+17-5x = 12x-4-5x
17 = 7x-4
Add 4 to each side
17+4 = 7x-4+4
21 = 7x
Divide by 7
21/7 = 7x/7
3 =x
Answer:
x = 3
Step-by-step explanation:
5x + 17 = 4(3x - 1)
Distribute on the right side.
5x + 17 = 12x - 4
Subtract 12x from both sides. Subtract 17 from both sides.
-7x = -21
Divide both sides by -7.
x = 3
A cube block has sides 8cm long. A cylindrical hole of radius 3.6 is drilled through the block. Find the volume of the block that remained
Answer:
186.45 cm^3
Step-by-step explanation:
Given data
Side lenght of cube block= 8cm
Radius of cylindrical hole= 3.6cm
Volume of entire Shape= l^3
Volume of entire Shape= 8*8*8
Volume of entire block= 512cm^3
Volume of cylindrical hole= πr^2h
Volume of cylindrical hole= 3.14*3.6^2*8
Volume of cylindrical hole= 3.14*12.96*8
Volume of cylindrical hole= 325.55cm^3
Hence the volume of the block
=volume of entire shape- volume of cylinder
=512-325.55
=186.45 cm^3
Find missing measure (No.5)
Answer:
Step-by-step explanation:
61+90+76+angle 2=360(sum of four angles is always 360 degree)
227+angle 2=360
angle 2=360-227
angle 2=133
angle 1=76 degree(being vertically opposite angle)
angle 1+angle 3+120+88=360(sum of four angles ia always 360 degree)
76+angle 3+208=360
angle 3=360-284
angle 3=76 degree

A line passes through the points (3, –1) and (5, 4). What is the slope of the line?
Answer:
D) 5/2
Step-by-step explanation:
(3, –1) and (5, 4)
Slope:
m=(y2-y1)/(x2-x1)
m=(4 + 1)/(5 - 3)
m= 5/2
Answer:
5/2
Step-by-step explanation:
To find the slope, we can use the slope formula
m= (y2-y1)/(x2-x1)
= (4 - -1)/(5 - 3)
= (4+1)/(5-3)
= 5/2
Find the area of the triangle
The area is __yd^2
Answer:
area of triangle = 4.5*6/2 = 13.5 sq.yd.
Step-by-step explanation:
The area of a right triangle is half of the product of the sides adjacent to the right angle.
Here the sides adjacent to the right angle are 6 yd and 4.5 yd.
Therefore the
area of triangle = 4.5*6/2 = 13.5 sq.yd.

Step-by-step explanation:
What are the coordinates of the point on the directed line segment from (-3, -2) to (4, 8) that partitions the segment into a ratio of 3:2?
Answer:
Since the ratio is 3:2, you will need to find the x and y coordinates that are 3/5 of the way between (-8,2) and (7,-3)
For the x-coordinate, find the distance between x coordinates (7--8) = 15, take 3/5 of that = 9 and add that to the first x coordinate (-8) to get the x-coordinate of interest (1).
For the y-coordinate, find the distance between y coordinates (-3-2) = -5 take 3/5 of that = -3 and add that to the first y coordinate (2) to get the y-coordinate of interest (-1
So the coordinate of the point is (-2,6)

5. Becca wants to edge her hexagonal garden
with brick. All sides are equal. The brick costs
$6 per yard. What is the perimeter of the
garden? How much will it cost to buy the
edging she needs?
Answer:
[tex](a)\ Perimeter = 6l[/tex]
[tex](b)\ Cost = \$36l[/tex]
Step-by-step explanation:
Given
[tex]l \to sides[/tex]
Solving (a): The perimeter
The shape has 6 sides; since the sides are equal, the perimeter is:
[tex]Perimeter = 6 * l[/tex]
[tex]Perimeter = 6l[/tex]
Solving (b): Cost of fencing
We have:
[tex]Unit\ cost = \$6/yd[/tex]
So, the cost is:
[tex]Cost = Unit\ cost * Perimeter[/tex]
[tex]Cost = \$6/yd * 6l[/tex]
[tex]Cost = \$36l[/tex]
To get the actual answer, substitute the length of one side of the hexagonal in the calculated expressions
noah took a long bike ride.he began at his house,riding 3 km west. he turned north and rode 5km . he took a turn to the east and rode 6km. next he rode south for 2km. noah turned west and rose 3km, then made one more turn to get home . which direction was his last turn and how far was the last leg of the trip
Answer:
His last turn was in West direction and his last leg of the trip is 6 Km away
Step-by-step explanation:
The direction and distance travelled is as follows
a) West - 3 Km
b) North - 6 Km
c) South 2 Km
d) West - 3 KM
At last he turned in the west direction and he travelled 3 Km + 3 Km = 6Km
