Choose the approximate value for eggs for the following similar triangles given below
The area of the triangle below is 3/25 square feet. What is the length of the base? Express your answer as a fraction in simplest form.
2/5 ft is the height
Answer:
b = 0.6 ft
Step-by-step explanation:
area = 3/25
area = 1/2bh
3/25 = 1/2b(2/5)
1/2b = (3/25)/(2/5) = 15/50 = 3/10 or 0.3
b = 2(0.3) = 0.6 ft
The length of the base as a fraction in the simplest form is 3/5 feet.
What is a Triangle?Every three-sided polygon having three edges and three vertices is referred to as a triangle in geometry. The most important attribute of a triangle is that its interior angles sum to 180 degrees. This characteristic is known as the triangle's angle sum property. Every triangle has a length, base and height.
As per the given data:
Area of the triangle (A) = (3/25) sq feet
Height of the triangle (h) = (2/5) feet
A = (1/2) × base × height
(3/25) = (1/2) × base × (2/5)
base = (3 × 2 × 5)/(25 × 2)
base = 15/25
base = 3/5 feet
Hence, the length of the base as a fraction in the simplest form is 3/5 feet.

g (15 points) Suppose 42 out of 600 rats exposed to a potential carcinogen develop tumors. A control group of 350 rats not exposed to the carcinogen develops 13 tumors. Based on these data, computed (a) the relative risk, (b) the attributable risk, and (c) the odds ratio. Do these indicators suggest that there is a relationship between exposure and tumor risk
Answer:
a) The relative risk is 1.8[tex]\overline{846153}[/tex]
b) The attributable risk is [tex]0.69 \overline{047619}[/tex]
c) There is a relationship between exposure and tumor risk
Step-by-step explanation:
The number of exposed rats that develop tumors, a = 42
The number of rats exposed to the carcinogen = 600 rats
The number of exposed rats that did not develop tumors, b = 600 - 42 = 558
The number of not exposed rats in the control group = 350 rats
The number of rats that develop tumors in the control group, c = 13 tumors
The number of not exposed rats that did not develop tumors, d = 350 - 13 = 337 rats
a) The relative risk, RR = a/(a + b)/(c/(c + d))
∴ RR = (42/(42 + 558))/(13/(13 + 337)) = 49/26 = 1.8[tex]\overline{846153}[/tex]
b) The attributable risk = (a - c)/a
∴ The attributable risk = (42 - 13)/42 = [tex]0.69 \overline{047619}[/tex]
c) The odds ratio = (a·b)/(c·d)
∴ The odds ratio = 42 × 558/(13 × 337) = 23439/4381 ≈ 5.35
Given that the result of attributable risk is positive, there is an indication that there is a higher probability to develop tumor when exposed to the potential carcinogen, therefore, there is a relationship between exposure and tumor risk

Answer:
Quintrell's number is 9.
Step-by-step explanation:
Let [tex]x[/tex] be equal to Quintrell's number.
"When 35 is added to my number, the answer is 4 times my original number plus 8."
⇒
[tex]35+x=4x+8[/tex]
Subtract both sides by [tex]x[/tex]
[tex]35+x-x=4x+8-x\\35=3x+8[/tex]
Subtract both sides by 8
[tex]35-8=3x+8-8\\27=3x[/tex]
Divide both sides by 3
[tex]\frac{27}{3} =\frac{3x}{3} \\9=x[/tex]
Therefore, Quintrell's number is 9.

Christine is 4 years younger than Mark. 3 years from now, she will be two-thirds as old as Mark find their present ages.Complete solution
Answer:Mark Is 9 years old; Christine is 5 years old
Step-by-step explanation:
Present age
LET mark age be x
Christine be x-4 yrs
In 3 yrs Time
Mark will be x+3 yrs old
Christine will be (x -4 +3) = x-1 years old
Also, In 3 years time
Christine = 2/3 Mark
such that
x-1 = 2/3(x+3)
x -1= 2x+6 / 3
3x -3= 2x+6
3X--2X = 6+3
=X=9
Mark Is 9 years old
Christine is x -4 = 9-4=5 years old

A. 450
B. 550
C. 625
D. 650
Answer: B:550. You do percent over 100 equals part over whole.you put 25 as your percent over 100 then you put 2,200 as your whole put x on part then you multiply 25x2,200=55,000 then you dived 55000 and 100 and you get 550
A quadrilateral has one pair of parallel sides with lengths 134 inches and 114 inches, and two angles that each measure 36°.
Answer:
Explanation:
1) The two parallel sides of different legths 1\frac{3}{4}143 and 1\frac{1}{4}141 constitute the bases of a trapezoid.
2) The two equal anglesare the base angles of the trapezoid, and mean that it is an isosceles trapezoid.
An isosceles trapezoid is truncated isosceles triangle.
The definition of trapezoid is a quadrilateral with at least two parallel sides.
The drawing is attached: only the green lines represent the figure, the dotted lines just show how this is derived from an isosceles triangle.
Which describes the cost to produce one item?
A. Benefit
B. Unit price
C. Fixed cost
D. Unit cost
Unit cost describes the cost to produce one item.
What is Cost?A cost is the value of money that has been used up to produce something or deliver a service
The unit cost is the cost associated with producing a single unit of a product or service.
It includes the direct and indirect costs of producing one item.
Direct costs can include the cost of raw materials, labor, and any other direct cost involved in the production of the item.
Indirect costs can include expenses like rent, utilities, equipment, and any other cost that is not directly associated with the production of a single unit, but is still necessary for the production process.
Hence, Unit cost describes the cost to produce one item.

How many solutions does the nonlinear system of equations graphed below have
Answer:
C. two
Step-by-step explanation:
2 points of intersection
Option C is correct, there are two solutions to the nonlinear system of equations graph.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
A system of nonlinear equations is a system of two or more equations in two or more variables containing at least one equation that is not linear.
In this case, we have a parabola (the red figure) and a line (the blue figure).
There are three possible types of solutions for a system of nonlinear equations involving a parabola and a line.
No solution. The line will never intersect the parabola.
One solution. The line is tangent to the parabola and intersects the parabola at exactly one point.
Two solutions. The line crosses on the inside of the parabola and intersects the parabola at two points.
Hence, there are two solutions to the nonlinear system of equations graph.

Assume that we have two variables a and b, and that: a = b
Multiply both sides by a to get: a2 = ab
Subtract b2 from both sides to get: a2 - b2 = ab - b2
This is the tricky part: Factor the left side (using FOIL from algebra) to get (a + b)(a - b) and factor out b from the right side to get b(a - b). If you're not sure how FOIL or factoring works, don't worry—you can check that this all works by multiplying everything out to see that it matches. The end result is that our equation has become: (a + b)(a - b) = b(a - b)
Since (a - b) appears on both sides, we can cancel it to get: a + b = b
Since a = b (that's the assumption we started with), we can substitute b in for a to get: b + b = b
Combining the two terms on the left gives us: 2b = b
Since b appears on both sides, we can divide through by b to get: 2 = 1
