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
Answers
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 quadrilateral has one pair of parallel sides with lengths 134 inches and 114 inches, and two angles that each measure 36°.
Answers
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.

How many solutions does the nonlinear system of equations graphed below have
Answers
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.

Mr.Pope is buying Mrs. Pope's flowers. He buys 6 flowers for 10.95 without tax.
How much did he pay for each flower?
a. $2.00
b. $1.82
c. $1.825
d. $1.83
Answers
He payed $10.95 for 6 flowers. You want to find the price per each flower.
An equation to model this situation would be 6x = 10.95 where x = price per flower.
To solve this divide each side by 6.
10.95/6 = 1.825
Essentially to find the price per an individual thing you need to divide the total price by the amount of the item purchased.
He payed $1.825 per flower.

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
Answers
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
