Answer:
a) $53.34
b) 84,360.9 gallons
Step-by-step explanation:
let 'x' = cost of bill for 30,000 gallons
a) i set up a proportion as follows:
$1.33/748g = x/30,000
i cross-multiplied and got $53.34
b) i set up a proportion as follows:
let 'y' = how many gallons $150 can buy
$1.33/748g = 150/y
i cross-multiplied and got 84,360.9 gallons
There are a total of 375 flamingos, parrots, herons, and chachalacas at the Famous
Bird Sanctuary. The ratio of flamingos to parrots to herons is 10:7:3, respectively.
There are twice as many flamingos as chachalacas. How many chachalacas are at the
sanctuary?
9514 1404 393
Answer:
75
Step-by-step explanation:
Since there are twice as many chachalacas as flamingos, the ratio of flamingos to parrots to herons to chachalacas is 10:7:3:5. This is a total of 25 ratio units. Each ratio unit stands for 375/25 = 15 birds, so the number of chachalacas is 5·15 = 75.
There are 75 chachalacas at the sanctuary.
A plane leaves an airport traveling at 400 mph in the direction N 45° E. A wind is blowing at 40 mph in the direction N 45° W. What is the ground speed of the plane?
400 mph
402 mph
429 mph
440 mph
Answer:
402 mph
Step-by-step explanation:
Draw a right triangle with 400 and 40 as the two legs.
You know this is a right angle because 45 degrees NE is perpendicular to 45 degrees NW. (imagine a compass)
So, the two side lengths are 400 and 40
Using the Pythagorean theorem, (a^2 + b^2 = c^2) you can see that the answer is 401.995, or 402
The ground speed of the plane is 402 mph , Option B is the correct answer.
What is a Right Angled Triangle ?A right angle triangle is a triangle with one of its sides 90 degree.
It is given that
airplane is travelling at speed of 400mph in the direction N 45° E
wind is blowing at 40 mph in the direction N 45° W
The resultant of these two vectors will be the ground speed of the plane.
As they both are travelling in perpendicular directions ( NE is perpendicular to NW)
A right angled Triangle as attached in the image will be formed
Hypotenuse by Pythagoras theorem will give the ground speed of the plane
Hypotenuse = [tex]\sqrt { 40 ^2 + 400^2}[/tex]
Hypotenuse = 401.99 mph
Therefore the ground speed of the plane is 402 mph.

Answer/Step-by-step explanation:
✔️Find EC using Cosine Rule:
EC² = DC² + DE² - 2*DC*DE*cos(D)
EC² = 27² + 14² - 2*27*14*cos(32)
EC² = 925 - 756*cos(32)
EC² = 283.875639
EC = √283.875639
EC = 16.85 cm
✔️Find the area of ∆DCE:
Area = ½*14*27*sin(32)
Area of ∆DCE = 100.15 cm²
✔️Since ∆DCE and ∆ABE are congruent, therefore,
Area of ∆ABE = 100.15 cm²
✔️Find the area of the sector:
Area of sector = 105/360*π*16.85²
Area = 260.16 cm² (nearest tenth)
✔️Therefore,
Area of the logo = 100.15 + 100.15 + 260.16 = 460.46 ≈ 460 cm² (to 2 S.F)

Answer:
The value of x is 9°
Step-by-step explanation:
The given parameters are;
ΔUVW with side UW extended to X
m∠UVW = (3x + 4)°
m∠VWX = (8x -12)°
m∠WUV = (x + 20)°
We have that m∠UVW + m∠WUV + m∠VWU = 180° (Sum of the interior angles of a triangle theorem)
∴ m∠VWU = 180° - (m∠UVW + m∠WUV)
Also we have that m∠VWX and m∠VWU are supplementary angles, (The sum of angles on a straight line)
∴ m∠VWX + m∠VWU = 180° (Definition of supplementary angles)
m∠VWU = 180° - m∠VWX
∴ m∠VWX = (m∠UVW + m∠WUV)
Substituting the values, gives;
(8x -12)° = (3x + 4)° + (x + 20)°
8x - 3x - x = 4 + 20 + 12
4x = 36
x = 36/4 = 9
x = 9°.

Answer:
47,04 miles
Step-by-step explanation:
you can clearly see something 20 feet away that you should be able to see from that distance. If a person can see 6 miles from a height of 25 feet, by dividing 196 by 25 we can get the following calculation
196 ÷ 25 = 7,84

(9,-4); slope=-2/3
Answer:
(y - y') = m ( x - x') [m = slope]
y - (-4) = 2/3 (x - 9)
(y +4) = 2/3 (x - 9)
3(y +4) = 2(x - 9)
3y +12 = 2x - 18
2x - 3y - 18 - 12 =0
2x - 3y - 30 =0

The equation of the line passing through (9, -4) having slope = -2/3 will be y = (-2/3)x + 2
What is the general equation of a Straight line?
The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
y = mx also represents direct proportionality. We can write [m] as -
m = y/x
OR
y₁/x₁ = y₂/x₂
Given is a line passing through (9, -4) having slope=-2/3.
The general equation of a straight line is -
[y] = [m]x + [c]
Now -
m = - 2/3
and
- 4 = -2/3 x 9 + c
- 4 = - 6 + c
c = - 4 + 6
c = 2
The equation will be -
y = (-2/3)x + 2
Therefore, the equation of the line passing through (9, -4) having slope = -2/3 will be y = (-2/3)x + 2

How many numbers between 4000 and 5000 can be formed with the
digits 2, 3, 4, 5, 6, 7? How many of these numbers are divisible by 5?
Answer:
36 numbers
Step-by-step explanation:
Number of digits in a number between 4000 and 5000 = 4
_ _ _ _
First digit of the number will be filled by 4.
So, the number of ways to fill the first digit = 1
4 _ _ _
If the given number is divisible by 5 then the last digit should be 5.
4 _ _ 5
So, the number of ways that the last digit should be 5 is = 1
Remaining 2 digits between 4 and 5 can be filled by any number given.
Therefore, number of ways that second place can be filled = 6
Similarly, number of ways that the third place of the number can be filled = 6
Now total number of ways = 1 × 6 × 6 × 1
= 36
Therefore, numbers between 4000 and 5000, divisible by 5 = 36

A window is twice as long as it is wide. The area of the window is 2x where x
is the width of the window. The window is surrounded by a frame that is 2 inches
on all sides. The area of the window and frame is 2x2 + 12x +16.
What is the area of the window frame?
Answer:
When we have a rectangle of length L and width W, the area is calculated as:
A = W*L
In this case, W = x, and the area is:
A = 2*x
Then we must have L = 2.
We know that the area of the window and the frame (together) is:
a = 2*x^2 + 12*x + 16
The area of the frame alone, will be equal to the difference between the area of both objects (a) and the area of the window alone (A)
area of the frame = a - A
= (2*x^2 + 12*x + 16) - (2*x) = (2*x^2 + 10*x + 16)
This is the area of the frame

Answer:
L = 5√10
Step-by-step explanation:
The Pythagorean theorem tells you the square of the hypotenuse is the sum of the squares of the other two sides.
(10√3)² = L² + (5√2)²
300 = L² + 50 . . . . . . . . . evaluate the squares
L² = 300 -50 = 250 . . . . subtract 50
L = √250 = (√25)(√10) . . . . take the square root and factor for simplification
L = 5√10
