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.
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

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

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).

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 factory makes car batteries. The probability that a battery is defective is 1/13. If 200 batteries are tested about how many are expected t be defective.
A. 20
B. 15
C. 187
D. 13
Answer:
defective battery=200×1/13=15.3=15 is your answer
Number of expected defective batteries are option(B) 15
What is Probability?Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.
Given,
Probability that a battery is defective = [tex]\frac{1}{13}[/tex]
Total number of batteries = 200 batteries
Number of expected defective batteries = [tex]200(\frac{1}{13})[/tex] ≅15 batteries
Hence, the number of expected defective batteries are option (B) 15 batteries
