what is 1 5/8 divided by 5 1/7
Answer: 91/288
Step-by-step explanation: To divide mixed numbers, first write the mixed numbers as improper fractions.
We can do this by multiplying the denominator by the whole number and then adding the numerator. Then, we put our new numerator over our old denominator.
So here, we can write 1 and 5/8 as the improper fraction 13/8 and we can write 5 and 1/7 as the improper fraction 36/7.
So here, we have 13/8 ÷ 36/7.
Dividing by a fraction is the same as multiplying by the reciprocal of that fraction.
So here, 13/8 ÷ 36/7 is the same as 13/8 × 7/36.
So now we are simply multiplying fractions and we do this by multiplying across the numerators and multiply across the denominators.
[tex]\frac{13}{8} x \frac{7}{36} = \frac{91}{288}[/tex]
So now we have 91/288 which is in lowest terms.
This means that 1 and 5/8 divided by 5 and 1/7 is 91/288.

Answer:
Domain: -∞ < x < +∞
Range : 2 ≤ f(x) < +∞
Step-by-step explanation:
See the graph attached to this question.
The two arrow shows the graph of a function y = f(x).
Now, the value of x varies from +∞ to -∞.
So, the domain of the function is -∞ < x < +∞
Again from the graph the range of the function i.e. values of y varies from 2 to +∞ and including 2.
Therefore, the range of the function is 2 ≤ f(x) < +∞ (Answer)
Tom planted 1/2 of an 8-ft by 9-ft garden with vegetables. He planted tomatoes in 1/3 of the vegetable garden and corn in the rest . What is the area planted in corn
Answer:
Corn was planted in 24 sq.ft. of the vegetable garden.
Step-by-step explanation:
Length of garden = 9 ft
width of garden = 8 ft
Hence we will first find the total area of garden.
Total area of garden = length × width = [tex]8 \times 9 = 72ft^2[/tex]
He planted 1/2 of the garden with vegetables.
Hence.
Area of Vegetables garden = [tex]\frac{1}{2}\times \textrm{Total Area of Garden} = \frac{1}{2}\times 72 = 36ft^2[/tex]
He planted tomatoes in 1/3 of the vegetable garden and corn in the rest
Area in which tomatoes was planted = [tex]\frac{1}{3}\times \textrm{Area of Vegetables Garden} = \frac{1}{3}\times 36 = 12ft^2[/tex]
Hence Area in which corn were planted = Area of Vegetables garden - Area in which tomatoes was planted = [tex]36ft^2-12ft^2=24ft^2[/tex]
Hence Area of vegetable garden in which corn was planted is 24 sq.ft.

Find the standard form of the equation of the parabola with a focus at (0, -3) and a directrix at y = 3. (5 points)
y^2 = -12x
y^2 = -3x
y = negative x^2 divided by 12
y = negative x^2 divided by 3
Answer:
From given option , the equation of parabola is y = negative x² divided by 12
Step-by-step explanation:
Given as for parabola :
The focus is at (0 , - 3)
The directrix equation is y = 3
Now, equation of parabola parallel to y-axis is
( x - h )² = 4 p ( y - k )
where focus is ( h , k+p ) and directrix equation is y = k - p
So, from equation
h = 0 and k + p = - 3
And y = k - p i.e k - p = 3
Now solving ( k + p ) + ( k - p ) = - 3 + 3
or, 2 k = 0 ∴ k = 0
Put the value of k , k + p = - 3
So, 0 + p = - 3 ∴ p = - 3
Now equation of parabola with h = 0 , k = 0 , p = - 3
( x - h )² = 4 p ( y - k )
I.e ( x - 0 )² = 4 × ( - 3 ) ( y - 0 )
Or, x² = - 12 y is the equation of parabola
Hence From given option , the equation of parabola is y = negative x² divided by 12 Answer
Determine m angle F by using the figure
Answer:
The measure of angle F is m∠F=130°
Step-by-step explanation:
step 1
Find the measure of angle E
we know that
An isosceles triangle has two equal sides and two equal interior angles
In this problem
DF=EF ----> given problem
so
Triangle DEF is an isosceles triangle
m∠D=m∠E
we have
m∠D=25°
substitute
m∠E=25°
step 2
Find the measure of angle F
we know that
The sum of the measures of the interior angles in a triangle must be equal to 180 degrees
so
m∠D+m∠E+m∠F=180°
substitute the values
25°+25°+m∠F=180°
50°+m∠F=180°
m∠F=180°-50°
m∠F=130°

You are given a circle of radius 12. What is the segment area of an arc that is 90 degrees?
Answer:
The segment area [tex]= 113.09\ unit^2[/tex]
Step-by-step explanation:
Area of the segment = [tex]\frac{(\theta)}{360} \times \pi r^2[/tex],where [tex]\theta[/tex] is the angle.
We can also say that [tex]90\ degrees[/tex] is covered with one segment and we have total [tex]4[/tex] segments (quadrants),so area of the circle divided by [tex]4[/tex] will give us the segement area of the arc.
So area [tex]\frac{\pi r^2 }{4} =\frac{\pi(12)^2}{4} = 113.09\ units^2[/tex]
So the area of the segment [tex]= 113.09 \ units^2[/tex]
The center of a circle lies on the line y = 3x + 1 and is tangent to the x-axis at (−2,0) .
What is the equation of the circle in standard form?
The equation of the circle in standard form is: (x + 2)² + (y - 1)² = 1
What is the equation of the circle?
The general form of the equation of a circle is:
(x - h)² + (y - k)² = r²
Where;
(h, K) is the coordinate of the center of the circle.
r is radius.
To find the equation of the circle in standard form, we need to determine the center and radius of the circle.
Since the center of the circle lies on the line y = 3x + 1 and is tangent to the x-axis at (-2,0), we can determine that the center of the circle is (-2,1) and the radius is 1.
Therefore, the equation of the circle in standard form is:
(x + 2)² + (y - 1)² = 1

Answer:
1. The required slope m, for the context is[tex]m = \frac{-25}{3}[/tex]
2. The y-intercept in the context is [tex]P_{2}(d) = y = 100[/tex]
3. The x-intercept of the linear model is [tex]d = x = 12[/tex]
Step-by-step explanation:
Given:
[tex]P_{2}(d) = \frac{-25}{3}\times d + 100[/tex]
Where,
[tex]P_{2}[/tex] is the number of phones.
d is the number of days he has worked that week.
This is a linear model type equation.
Can be represented in the slope intercept form which is equal to
[tex]y = mx + c[/tex]
Where,
m = Slope of the line.
c = y-intercept.
Now if we compare the given model by slope intercept formula we get
[tex]m = \frac{-25}{3}\\\\c = 100[/tex]
So ,the slope in the context of the problem is [tex]m = \frac{-25}{3}[/tex].
and the y intercept in the context of the problem [tex]P_{2}(d) = c = y = 100[/tex]
For finding x-intercept put y = 0
Here,[tex]P_{2}(d) = 0[/tex]
[tex]\therefore 0 = \frac{-25}{3}\times d + 100\\ \therefore \frac{25}{3}\times d = 100\\\therefore d=\frac{300}{25}\\\therefore d=12[/tex]
So, the x intercept of the linear model is [tex]d = x = 12[/tex]

PLEASE HELP ASAP with questions 12 and 13
Answer:
12. x = 50
13. m∠M = 34°
Step-by-step explanation:
12.
Since the triangles are congruent, the sides' lengths are proportional. We can set up a ratio and solve for x.
Side JG corresponds to Side KM
Side HG corresponds to Side LM
Now, we can set up a ratio, cross multiply, and solve for x. Shown below:
[tex]\frac{35}{70}=\frac{25}{x}\\35x=70*25\\35x=1750\\x=\frac{1750}{35}\\x=50[/tex]
Thus, the value of x is 50
13.
The triangles are similar, so sides are proportional and angles are not related in the same way. Angles are same for both.
We want the value of Angle M, that angle corresponds to Angle G of the left triangle.
It is given that Angle G = 34, so Angle M would be the same degree measure as well.
Hence,
m∠M = 34°

Quick question what’s 2ab+3b+7b+3a•3a•b+4b-8ab•8ab+5a•5a•b-12ab?
Answer:
14b - 10ab + 34a²b - 64a²b²
Step-by-step explanation:
We have to simplify the expression
2ab + 3b + 7b + 3a × 3a × b + 4b - 8ab × 8ab + 5a × 5a × b - 12ab
= 2ab + 3b + 7b + 9a²b + 4b - 64a²b² + 25a²b - 12ab
{Since (3a × 3a × b) = 9a²b, (8ab × 8ab) = 64a²b² and (5a × 5a × b) = 25a²b}
= 2ab + 10b + 9a²b + 4b - 64a²b² + 25a²b - 12ab
= 14b - 10ab + 34a²b - 64a²b² (Answer)
County fair charges 1.25 per ticket for rides. Tom bought 25 ride tickets and spent a total of $43.75 total for rides and admission. The price of admission is the same for everyone. Use y to represent total cost and x for the number of tickets.
Define variables
Write linear equation to determine the cost for rides tickets and admission
Answer:
The linear equation is 1.25x + 0.5x = y
Step-by-step explanation:
1. Let's review the data given to us for solving the question:
Price of ride ticket at country fair = US$ 1.25
Total spent by Tom for rides and admission= US$ 43.75
Number of ride tickets bought by Tom = 25
Price of admission is the same for everyone
Total cost = y
Number of tickets = x
2. Let's find out the cost of the admission:
Total cost of ride tickets + Total cost of admission = Total cost of rides tickets and admission
Replacing with real values:
1.25 * 25 + Cost of admission * 25 = 43.75
31.25 + 25 * Cost of admission = 43.75
25 * Cost of admission = 43.75 - 31.25 (Subtracting 31.25 at both sides)
25 * Cost of admission = 12.50
Cost of admission = 12.50/25 (Dividing by 25 at both sides)
Cost of admission = 0.50
3. Let's write a linear equation to determine the cost for rides tickets and admission:
Total cost of ride tickets + Total cost of admission = Total cost of rides tickets and admission
Total cost = y
Number of tickets = x
1.25x + 0.5x = y
At a local fitness center, members pay a $12 membership fee and $2 for each aerobics class. Nonmembers pay $4 for each aerobics class. For what number of aerobics classes will the cost for members and nonmembers be the same?
Final answer:
The costs for members and nonmembers of a local fitness center will be the same after attending 6 aerobics classes. Members have an initial $12 membership fee plus $2 per class, while nonmembers pay $4 per class.
Explanation:
To find the number of aerobics classes for which the cost for members and nonmembers will be the same, we need to set up an equation that compares the two cost structures. For members, the cost is a $12 membership fee plus $2 per class, which we can express as Cm = 12 + 2n, where Cm is the cost for members and n is the number of classes. For nonmembers, the cost is $4 per class, so we can express that as Cnm = 4n, where Cnm is the cost for nonmembers.To find the number of classes where costs are the same, we set Cm equal to Cnm:
Subtract 2n from both sides: 12 = 2n
Divide both sides by 2: n = 6
Therefore, the costs for members and nonmembers will be the same when they attend 6 aerobics classes.
Write the slope intercept form of the equation of the line through the given points and slope 1,1 and slope of -3/5
Slope is already given in the question so we only need to solve for the y-intercept.
Slope intercept form: y = mx + b
m = slope
b = y-intercept
-3/5 = -0.6
1 = -0.6(1) + b
1 = -0.6 + b
1 + 0.6 = -0.6 + b + 0.6
1.6 = b
Now, write in slope-intercept form.
y = -3/5x - 1.6
