Answer:
52:49
Step-by-step explanation:
pink:green
The ratio of pink to green marbles is
3k:4k
He removes 5 green marbles and adds 8 pink marbles.
Now the ratio of pink to green marbles is
(3k + 8):(4k - 5)
This rario is equal to 29:23.
(3k + 8)/(4k - 5) = 29/23
29(4k - 5) = 23(3k + 8)
116k - 145 = 69k + 184
47k = 329
k = 7
Original amounts:
3 * k = 3 * 7 = 21 pink
4 * k = 4 * 7 = 28 green
Original total = 21 + 28 = 49
Amounts after replacement:
3k + 8 = 3(7) + 8 = 29 pink
4k - 5 = 4(7) - 5 = 23 green
Total after replacement = 23 + 29 = 52
Answer: The ratio of the total number of marbles in the jar after replacement to the total number of marbles in the jar originally is 52:49.

Answer:
20% profit
Step-by-step explanation:
Given:
Cost = 1450Sold for = 1740Profit:
1740 - 1450 = 290Profit percent:
290/1450*100% = 20%Answer:
c.p=1450
s.p=1740
profit=s.p-c.p

solve for y 4y-36x=28
Answer:
[tex]y = 9x + 7[/tex]
Step-by-step explanation:
To solve for y, our goal is to get it isolated on one side of the equation.
[tex]4y - 36x = 28[/tex]
Let's add [tex]36x[/tex] to both sides of the equation.
[tex]4y = 36x + 28[/tex]
Now divide both sides by 4.
[tex]y = 9x + 7[/tex]
Hope this helped!
Answer:
4y-36x = 28........... :4
y-9x = 7
y = 7+9x or y = 9x+7

Determine the value of x in the figure.
Question 20 options:
A)
x = 9
B)
x = 3
C)
x = 6
D)
x = 4.5
Step-by-step explanation:
Hey there!
Your required answer is option B.
Here,
Given,
The figure is an equilateral triangle with, side (7x+9) and (x+27).
By the defination of equilateral triangle we have,
All sides of equilateral triangle are equal.
So,
[tex]( 7x+ 9) = x + 27[/tex]
Simplify them to get answer.
[tex]7x - x = 27 - 9[/tex]
[tex]6x = 18[/tex]
[tex]x = \frac{18}{6} [/tex]
Therefore the value of x is 3.
Hope it helps...
The value of x in the figure is:
B) x = 3
How to determine the value of x in the figure?Trigonometry deals with the relationship between the ratios of the sides of a right-angled triangle with its angles.
The signs on the three sides of the triangle indicate that all the sides of the figure are equal. Thus, we can say:
7x + 9 = x + 27
7x - x = 27 - 9
6x = 18
x = 18/6
x = 3
Therefore, the value of x is 3.

Find the number if:
Step-by-step explanation:
Let the number be x
1 2/3% × x = 4.75
5/3% × x = 4.75
(5/3)/100 × x = 4.75
5/3 × 1/100 × x = 4.75
5x/300 = 4.75
5x = 300 × 4.75
x = (300 × 4.75)/5
x = 1425/5

Answer:
d(3) = - 25
Step-by-step explanation:
Using the recursive formula with d(1) = 3, then
d(2) = d(1) - 14 = 3 - 14 = - 11
d(3) = d(2) - 14 = - 11 - 14 = - 25
Thus the 3 rd term in the sequence is - 25
Why is the answer true?
Hello, one way to see it is as below
[tex]\displaystyle F(2)-F(1)=\int_1^2 F'(t) dt=\int_1^2 G'(t) dt=G(2)-G(1)[/tex]
Another way is to notice that F'(x)=G'(x) means that F(x) and G(x) are only different from a real constant that we can note a, it means that
[tex](\forall x \in \mathbb{R}) \ (F'(x)=G'(x)) => (\exists a \in \mathbb{R});(F(x)=G(x)+a)[/tex]
and then F(2)-F(1)=G(2)-G(1)

A delivery company uses cars, cargo vans, and semitrailers. The company uses its cargo vans to deliver packages to locations at a 75-mile radius
from the warehouse. If the distance to the delivery location is within 8 miles of the delivery boundary, a cargo van will still be used. The company
uses the other vehicles for any distance outside this range.
Write an inequality to represent the instances when a vehicle other than a cargo van is used, where x is the distance of a location from the warehouse.
Given that:
The company uses its cargo vans to deliver packages to locations at a 75-mile radius from the warehouse.
If delivery location is within 8 miles of the delivery boundary, a cargo van will still be used.
To find: The inequality to represent the instances when a vehicle other than a cargo van is used.
Solution:
Let x is the distance of a location from the warehouse.
Cargo van will be used if delivery location is within 8 miles of the delivery boundary.
Minimum distance for delivery = 75-8 = 67 miles.
Maximum distance for delivery = 75+8 = 83 miles.
So, the company uses cargo vans for any distance in the range 67 miles to 83 miles. So,
[tex]67\leq x\leq 83[/tex]
Therefore, the required inequality is [tex]67\leq x\leq 83[/tex].

Write the equation of a line perpendicular to the line:
y=−3/4x+5 that goes through the point (-1, -10).
Write your answer in slope- intercept form, using reduced fractions for the slope and intercept.
Answer:
y= 4/3x - 8.7777777777(reoccurring)
Step-by-step explanation:
ok for perpendicular slopes we use the negative reciprocal of the original slope so -3/4 turns into 4/3. next we take the equation y = 4/3x + b and plug in -1 for x and -10 for y to find B.

The required translated figure of a triangle ABC is shown in the image attached.
Question asked to draw the image of ABC under translation by 3 units to the right and 4 units down.
What is translation?A translation is defined as a type of conversion that takes an individual point in a figure and slides it the same distance in the same direction.
Since the translation of the figure is shifting the figure through certain specified units. because of translation, there is no cause to changes to the measure of the figure. the new figure formed will be congruent to the former figure.
As per the question, we have a triangle ABC, Let applied all the translation processes to point C. coordinate of C is (-3, 1) after translation 3 units right and 4 unit down the new coordinates are (0, -3). similarly Coordinates of A and B also changed corresponding to C.
Thus, the required translated figure of a triangle ABC is shown in the image attached.

If angle 1 and angle 2 form a linear pair and angle 1 is less than five times the measure of angle 2 find x and angle 1
Answer:
Angle 1 is 30° and angle 2 is 150°
Step-by-step explanation:
Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.Let angle 1 is a, angle 2 is b and we got b = 5a
a + b = 180°b = 5aa + 5a = 6a6a = 180°a = 180°/6a = 30°and
b = 5*30° = 150°What point does this line pass through?

Is 1/4 and 4/16 an equivalent fraction? If so why ?
Answer:
Yes
Step-by-step explanation:
1/4 = 4/16 because 1/4 of 16 is 4
Also,
1/4 is just a simplified version of 4/16
The answer to whether 1/4 and 4/16 are equivalent fractions is that; Yes, they are equivalent fractions
How to simplify Fractions?We have two fractions which are; 1/4 and 4/16
Now, the first fraction is already in simplified form and can't be simplified further. However, the second fraction can be further simplified.
For the second fraction which is 4/16, the numerator and denominators have a common term which is 4. Thus, we can factor it out to get;
(4/4) * (1/4)
4/4 =1 and so we see that 4/16 can be reduced to the first fraction and so they are the same.

Find the critical point of the function f(x) = x2 – 2x + 7.
Answer:
[tex]x=1[/tex] is a critical point of the function [tex]f(x).[/tex]
Step-by-step explanation:
[tex]f(x)=x^2-2x+7[/tex]
Differentiate both sides w.r.t. [tex]x[/tex]
[tex]\Rightarrow f'(x)=2x-2[/tex]
Now, [tex]f'(x)=0[/tex]
[tex]\therefore 2x-2=0[/tex]
[tex]\Rightarrow 2x=2[/tex]
[tex]\Rightarrow x=1[/tex]
Hence, [tex]x=1[/tex] is a critical point of the given function.
