What is 0.¯47 expressed as a fraction in simplest form?
Answer:
show work on how you did it
Answers
The computation of the figure illustrates that 0.47 expressed as a fraction in simplest form is 43/90.
How to compute the fraction?From the information given, let a = 0.47. Now 10a = 4.777 .... equation i
100a = 47.77 ..... equation ii
Subtract equation i from ii
100a - 10a = 47 - 4
90a = 43
Divide both side by 90
90a/90 = 43/90
a = 43/90

Find the equation of the tangent to the curve y = 4x³- 5x² + x - 3 at the point where it crosses the y axis.
Answers
Answer:
y = x-3
Step-by-step explanation:
When the graph of this equation crosses the y - axis , the value of x is = 0.
sub in zero to find this y value = -3
so the point is (0, -3)
Now find the drivative of this equation....the derivative tells you the slope of the original graph at any given point
derivative = 12x^2-10x+1 this , when x = 0 shows slope = 1
the equation then becomes y = (1) x -3 or just y = x-3

Step-by-step explanation:
Isolate x for 4x +y=9: x=9-y/4
Substitute x = 9-y/4
[5 x 9-y/4+2y =9]
Isolate y for (45+3y/4)=9:
y=-3
For x= 9-y/4
Substitute y = -3
x= 9-(-3)/4

the number of boys and the sum received by each.Explanation -
Here as we are required to find the value of two different individuals hence first we will from 2 linear equations into two variables (taking each to be value as x and y or whatever you like, I will take them as a and b) will solve the equation by any method of your choice (explanation for them is in the link, below, it is given by the same me)
https://brainly.com/question/27161912?utm_source=android&utm_medium=share&utm_campaign=question
Solution -
Let the sum of money that was given to each boy be a and the number of boys be b. Hence, the total no. of money distributed to b no. of boys is ab.
According to the question,
Scenario 1 -
➡ (a + 2)(b - 10) = ab
Solving it further,
➡ a(b - 10) + 2(b - 10)= ab
➡ ab - 10a + 2b - 20= ab
Cancelling ab,
➡ 10a - 2b + 20 = 0
➡ 10a = 2b - 20
➡ a = 2(b - 10)/10
➡ a = (b - 10)/5
Scenario 2 -
➡ (a - 2)(b + 15) = ab
Solving it further,
➡ a(b + 15) - 2(b + 15)= ab
➡ ab + 15a - 2b - 30= ab
Cancelling ab,
➡ 15a - 2b - 30 = 0
Substituting the value of a in the equation,
➡ 15{(b - 10)/5} - 2b - 30 = 0
➡ 3(b - 10) - 2b - 30 = 0
➡ 3b - 30 - 2b - 30 = 0
➡ 3b - 2b -60 = 0
➡ b = 60
Substituting the value of b in a = (b - 10)/5,
➡ a = (60 - 10)/5
➡ a = 50/5
➡ a = 10
[Here we have used the substitution method]
Henceforth, the total number of boys is 60 and the sum received by each is Rs. 10 .

Answers
Answer:
109.88 ft² (nearest hundredth)
Step-by-step explanation:
Formulae
Area of a rectangle = width × lengthArea of a circle = πr²To find the area of the lawn that is not watered, subtract the area of the 2 circles from the area of the rectangle.
From inspection of the diagram
width of rectangle = 2rlength of rectangle = 4rarea = 512 ft²Substituting the values into the area of a rectangle formula, and solving for r:
⇒ 512 = 2r × 4r
⇒ 512 = 8r²
⇒ r² = 64
⇒ r = ±8
As distance is positive, r = 8 ft
Area of one circle = π8² = 64π ft²
Therefore,
Area not watered = area of rectangle - 2 × area of circle
= 512 - 2(64π)
= 109.88 ft² (nearest hundredth)

Write a compound inequality to determine the Fahrenheit temperature range at which the antifreeze protects the car.
Answers
Answer:
see below
Step-by-step explanation:
The label on the car's antifreeze container claims to protect the car between -40°C and 125°C.
So inequality which models this situation will be -40°C < T < 125°C
Now we have to show this inequality in Fahrenheit temperature with the help of [tex]C=\frac{5}{9} (F-32)[/tex]
So the compound inequality in Fahrenheit temperature will be
[tex]-40 < \frac{5}{9} (F-32) < 125[/tex]
