Answer:
4/15
Step-by-step explanation:
To simplify this question, to make it easier to be solved, we try and make sure that all the fractions have the same denominator. This is done by saying
4/5
2/3
8/15
2/5
From the aforelisted numbers, the highest denominator is 15, and thus, we try to make all the denominators 15
4/5 * 3/3 = 12/15
2/3 * 5/5 = 10/15
8/15 * 1/1 = 8/15
2/5 * 3/3 = 6/15
I multiplied it that way, so that it's decimal value doesn't change, even as it gives us the required fraction.
From the new crop of fractions, we have
12/15
10/15
8/15
6/15
If there's anything, we can tell that the sequence is reducing in a -2/15 rate, and thus, our next sequence has to be 4/15

Answer: 1/5
Step-by-step explanation:
You have to divide the numerator and the denominator by the GCF ( greatest common factor) of 11 and 55. 11 is the GCF of 11 and 55 so 11÷11=1 and 55÷11=5
Hope this helps :)

A culture of yeast doubles in size every 4 hours. If the yeast population is estimated to be 3 million now, what will it be one day from now
Answer:
192,000,000
Step-by-step explanation:
Given
General form of an Exponential distribution :
y = ab^x
a = initial amount = 3000000
b = growth factor = 2
x = period = 24 / 4 = 6
y = final amount ; after one day = 24 hours ; x = 24 /4 = 6
y = 3000000(2)^6
y = 3000000 * 64
y = 192,000,000

zh
Answer:
its 250 + 530 = 349893
Step-by-step explanation:
Determine the coordinates of the pre-image?
Just find the coordinates and divide the x and y coordinates by the scale factor.
I'll do A.
(4,3)
Divide 4 by 0.5 and 3 by 0.5.
4/0.5=2
3/0.5=1.5
So the original coordinate for A is (2,1.5).

What is the equation for the translation of x2 + y2 = 81 six units to the left and five units up?
Type the expression that results from the following series of steps:
Start with y, add 7, multiply by 3, then subtract 6.
Answer:
start with y
y
add 7
y+7
multiply by 3
3(y+7)
subtract 6
3(y+7)-6
therefore the answer is:
3y + 21 - 6
=
3y + 15 or 3(y+5)

Find an
explicit formula for the arithmetic sequence 37, 74, 111, 148, ....
Note: the first term should be a(1).
Answer:
Step-by-step explanation:
a₁ = 37
a₂ = 74
Common difference d = a₂ - a₁ = 37
nth term = a₁ + (n-1)d
= 37 + (n-1)37
= 37n
Answer:
Below in bold.
Step-by-step explanation:
The common difference is 74-37 = 37.
nth term a(n) = a1 + (n - 1)d
= 37 + 37(n - 1)
= 37n.
A shape is made of 9 right triangles of equal size and three identical rectangles.
Each rectangle measures 7 mm wide by 3 mm high. The rectangles are each
7 mm wide by 3 mm high. What is the total area, in square millimeters,
of the shape?
Answer:
The area of the figure is 157.5 square millimeters.
Step-by-step explanation:
Since a shape is made of 9 right triangles of equal size and three identical rectangles, and each rectangle measures 7 mm wide by 3 mm high, while the rectangles are each 7 mm wide by 3 mm high, to determine what is the total area, in square millimeters, of the shape, the following calculations must be performed:
Area of a rectangle: base x height
Area of a triangle: (base x height) / 2
7x3 = 21 = Rectangle area
7x3 / 2 = 10.5 = Triangle area
21 x 3 + 10.5 x 9 = 157.5
Thus, the area of the figure is 157.5 square millimeters.

Write an equation of the line that passes through the points (3,8) and (2.6). Write the equation in slope-intercept form.
The equation of the line in slope-intercept form is
Answer:
2x - y + 2 = 0 is the equation
y = 2x + 2 is the equation in slope-intercept form
Step-by-step explanation:
slope = (y₂ - y₁) / (x₂ - x₁)
slope = (6 - 8) / (2 - 3)
slope = -2 / -1
slope (m) = 2
equation through the points (3,8) and (2,6):
(y - y₁) / (y₂ - y₁) = (x - x₁) / (x₂ - x₁)
(y - 8) / (6 - 8) = (x - 3) / (2 - 3)
(y - 8) / -2 = (x - 3) / -1
-y + 8 = -2x + 6
2x - y + 2 = 0
slope-intercept form,
y = mx + c
y = 2x + 2

You want to send a package . First class mail costs $.39 for the first ounce and $.24 for each additional ounce . You can spend at most $ 3.00 on postage . What is the maximum weight of your package ? Round down to the nearest ounce .
Answer: 10 ounces
Step-by-step explanation: Ounce is equal to O and price is y
y=mx+b : y=.24o+.39
y = 3.00
3.00-.39=2.61
2.61/.24 = 10.875
round it down and you get the maximum

-42 x 102
14 x 103
Answer:
10) 6 × 10⁷
11) -3 × 10⁻¹
Step-by-step explanation:
Assuming that (2 x 103)(3 x 104) =
(2 × 10³)(3 × 10⁴) =
(2 × 10³) × (3 × 10⁴)
And the division of
(-42 x 102) and (14 x 103) =
(-4.2 × 10²) ÷ (1.4 × 10³)

Find the measures of the interior angles of the triangle
Answer:
m∡A = 59°
m∡B = 48°
m∡C = 73°
Step-by-step explanation:
'x' = measure ∡A
73 + x - 11 + x = 180
2x + 62 = 180
2x = 118
x = 59
