Ali and mo share a sum of money in the ratio ali : mo = 9 : 7 ali receives 600 more than mo calculate how much each receives
Step-by-step explanation:
Given :-
Ali and mo share a sum of money in the ratio ali : mo = 9 : 7 .Ali receives 600 more than mo .And we need to find out how much each receives .Let us take that
Mo received x .Ali will get x + 600.According to the Question :-
[tex]\implies \dfrac{9}{7}=\dfrac{x+600}{x}\\\\\implies 9x = 7x + 4200 \\\\\implies 2x = 4200 \\\\\implies x = 2100 [/tex]
Therefore :-
Ali = x+600 = 2700Mo = x = 2100Answer:
ali:mo=937.5 and 262.5

During the first 4 years after the fire, she records 2, 6, 18, and 54 trees. If this trend continues, which
expression can be used to find the number of trees after n years?
Answer:
The expression is [tex]T(n) = 2*(3)^n[/tex]
Step-by-step explanation:
Geometric sequence:
In a geometric sequence, the quotient between consecutive terms is always the same.
The general rule of an geometric sequence is given by:
[tex]T(n) = T(0)(q)^n[/tex]
In which T(0) is the initial amount and q is the quotient.
During the first 4 years after the fire, she records 2, 6, 18, and 54 trees.
First term is 2, so [tex]T(0) = 2[/tex].
Quotient is [tex]q = \frac{54}{18} = \frac{18}{6} = \frac{6}{2} = 3[/tex]
So
[tex]T(n) = T(0)(q)^n[/tex]
[tex]T(n) = 2*(3)^n[/tex]
The expression is [tex]T(n) = 2*(3)^n[/tex]
You buy a gallon of milk that costs $3.50. The milk is discounted for 10% off. You also have to pay tax of 6.25% on the discounted price. What is the final cost?
Answer: ($3.50- 10% = 3.4)
( 3.4 + 6.25% = $3.46 or 3.4625 )
Step-by-step explanation:
The final cost of milk is $ 3.36875
What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
price of galloon of milk = $3.50
Discount = 10%
tax = 6.25%
Now, price after discount
=3.5 x 0.10
= 0.35
and, after tax
=3.5 x 0. 0625
= 0.21875
Hence, final cost of milk = 3.5 -0.35 + 0.21875= $ 3.36875

H=(...-2,-10,1,2,...3what type of set is H
A : empty set
B: finite set
C: infinity set
D: universal set
Answer: Universal set
Step-by-step explanation:
A universal set is usually represented by U and it is set that has all the elements of a related sets.
For example, if there are two sets which are X and Y. Let's say X = {1,2,3} and Y = {1,a,b,c}, therefore, the universal set will be U = {1,2,3,a,b,c}.
In the above scenario, H(...-2,-10,1,2,...3) is a Universal set.

What is coordinate geometry?A coordinate plane is a 2D plane created by the junction of the x-axis and y-axis, two perpendicular lines. A coordinate system in geometry is a way to use one or more integers or coordinates to determine the positions of the points.
Given points are (1,3) and (5,6). The distance between the points will be calculated as below:-
D = √ [ ( y₂ - y₁ )² + ( x₂ - x₁ )² ]
Substituting the given values, we get:
D = √((3 - (-3))² + (-4 - 4)²)
D = √(6² + (-8)²)
D = √(36 + 64)
D = √(100)
D = 10
Therefore, the distance between the two points (-3, 4) and (3, -4) is 10 units.

Let us find the width
Area= Length*Width
64= 8* Width
Width= 64/8
Width= 8ft
Hence the perimeter= 2L+2W

Find the measure of x and y.
Answer:
x = 24°, y = 53°
Step-by-step explanation:
An inscribed angle is half the measure of its intercepted arc.
arc EC = 2 × ∠ EDC = 2 × 78° = 156°
x = arc BE = 180° - arc EC = 180° - 156° = 24°
------------------------------------------------------------------
arc CD = 2 × CED = 2 × 41° = 82°
arc BD = 180° - arc CD = 180° - 82° = 98° , then
∠ BCD = [tex]\frac{1}{2}[/tex] × 98° = 49°
Then
y + 78° + 49° = 180° (sum of angles in triangle )
y + 127° = 180° ( subtract 127° from both sides )
y = 53°

58.8×1011
5.88×10-12
Answer:
5.88 x 1012
Step-by-step explanation:
To write each of these numbers in decimal notation, you move the decimal point the same number of places as the exponent. If the exponent is positive, move the decimal point to the right. If the exponent is negative, move the decimal point to the left. If you start at the decimal of 5.88 and move it 12 spaces to the right, then you get 5,880,000,000,000 miles.
The number represented in scientific notation is 5.88×1013.
What is scientific notation?It is the way of writing a large number between 1 to 10 with a power of 10.
We have,
5,880,000,000,000 miles is equivalent to 1 light year.
We can convert this number to scientific notation by moving the decimal point 13 places to the left
(because there are 13 zeros in 5,880,000,000,000) and multiplying by 10 raised to the 13th power:
So,
= 5,880,000,000,000
= 5.88 × 10¹³

Laurie is trying to stay within 10 feet of her current diving depth of -30 feet (with regard to sea level) so that the light
is still good but she can be close to the sea life during her scuba dive. Which two equations can be used to find the
minimum and maximum depths Laurie wants to stay between?
-30 - x = 10 and -30 - x = -10
• -30 + x = 10 and -30 + x = -10
O x + 10 = 30 and x + 10 = -30
O x - 10 = 30 and x - 10 = -3
Answer:
[tex] \boxed{-30\:– \: x \:= \: 10 \: \: and \: -30 - x = -10} [/tex]
The equations can be used to find the minimum and maximum depths are (a) [tex]-30 - x = 10[/tex] and [tex]-30 - x = -10[/tex]
The current diving depth (d) is given as:
[tex]d = -30ft[/tex]
The position (p) she tries to stay is given as:

A circle with a center at (2,-3) passes through the point (-1,-8). Write the equation of the circle.
Answer: (x - 2)^2 + (y + 3)^2 = 34
Step-by-step explanation:
The basic equation for a circle is
(x - a)^2 + (y - b)^2 = r^2 where (a, b) is the centre of the circle
Using Pythagoras we can find r^2
r^2 = (2 - -1)^2 + (-3 - -8)^2
= 3^2 + 5^2
= 34
So the circle is (x - 2)^2 + (y - -3)^2 = 34
The Equation of Circle is (x -2)² + ( y + 3)² = 34.
What is Equation of Circle?The standard equation of a circle is given by: (x-h)² + (y-k)² = r². Where (h,k) is the coordinates of center of the circle and r is the radius.
We know the standard form of Equation of Circle
(x - a)² + (y - b)² = r²
where (a, b) is the Centre of the circle
Also, we have a circle with a center at (2,-3) passes through the point (-1,-8).
Using Pythagoras theorem
r² = (2 - -1)² + (-3 - -8)²
= 3² + 5²
= 34
Thus, the Equation of Circle is (x -2)² + ( y + 3)² = 34.

Given that mDE = 49° and mFG = 12°, find mFE.
Answer:
mFE = 119°Explanation:
mGB = 90°
mGB = mBD
∴ mGD = 180°
⇒ mFE = 180 - (mDE + mFG)
mFE = 180 - (49 + 12)
mFE = 180 - 61
mFE = 119°
Answer:
119°
Step-by-step explanation:
[tex] In\: \odot A, [/tex] GD is diameter.
[tex] \therefore m\widehat{GFD} = 180\degree [/tex]
[tex] \because m\widehat {FG} +m\widehat {DE} = m\widehat {FE} \widehat{GFD} [/tex]
[tex] \therefore m\widehat {FG} +m\widehat {DE} + m\widehat {FE} = 180\degree [/tex]
[tex] \therefore 49\degree +12\degree + m\widehat {FE} = 180\degree [/tex]

The fish population is decreasing at a rate of 3% per year. In 2002 there were about 2100 fish. Find the fish population in 2010. Round to the nearest whole number
Answer:
Population of fish in 2010 = 1,646 fish (Approx.)
Step-by-step explanation:
Given:
Population of fish in 2002 = 2100 fish
Decrease rate = 3% per year
Find:
Population of fish in 2010
Computation:
Number of year = 2010 - 2002
Number of year = 8 year
A = P[1+r]ⁿ
Population of fish in 2010 = Population of fish in 2002[1+(-3%)]ⁿ
Population of fish in 2010 = 2100[1-0.03]⁸
Population of fish in 2010 = 2100[0.97]⁸
Population of fish in 2010 = 2100[0.7837]
Population of fish in 2010 = 1645.77
Population of fish in 2010 = 1,646 fish (Approx.)
