The table shows a ratio used to make orange paint. Using the table, how many quarts of yellow paint would be required to make this shade of orange if you used 9 quarts of red paint?
Answer:
7.5
Step-by-step explanation:
To make orange-shaded paint if we use 9 quarts of red paint we need 7.5 quarts of yellow paint.
What are ratio and proportion?A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
Given to make an orange shade paint 5 quarts of yellow paint and 6 quarts of red paint are needed.
Assuming the no. of yellow paint needed is x when 9 quarts of red paint is used.
As they are in direct proportion we can write
5 : 6 : : x : 9.
5/6 = x/9.
6x = 45.
x = 7.5.

What values of u and v make triangle XYZ = Triangle GFH
Answers:
u = 18
v = 20
========================================================
Work Shown:
The leg YZ is congruent to the left FH
This means YZ = FH and that leads to u+v-18 = 10u-8v
The hypotenuse ZX is congruent to the hypotenuse HG
This means ZX = HG and we get the equation 14v-14u+32 = v+u+22
----------------------
The system of equations we have so far is
u+v-18 = 10u-8v
14v-14u+32 = v+u+22
Let's get the equations into standard form
Start with the first equation
u+v-18 = 10u-8v
u+v = 10u-8v+18
u+v-10u+8v = 18
-9u+9v = 18
-9(u-v) = 18
u-v = 18/(-9)
u-v = -2
Note how we can solve for the variable u to get
u = v-2
which we'll use later
----------------------
Let's get the other equation into standard form as well
14v-14u+32 = v+u+22
14v-14u-v-u = 22-32
-15u+13v = -10
Now plug in u = v-2 and solve for v
-15u+13v = -10
-15(v-2) + 13v = -10
-15v+30+13v = -10
-2v+30 = -10
-2v = -10-30
-2v = -40
v = -40/(-2)
v = 20
Which means,
u = v-2
u = 20-2
u = 18

Which expression is equivalent to StartRoot negative 108 EndRoot minus StartRoot negative 3 EndRoot?
5 StartRoot 3 EndRoot i
6 StartRoot 3 EndRoot i
7 StartRoot 3 EndRoot i
8 StartRoot 3 EndRoot i
(4√5)i
Step-by-step explanation:
Complex number is a number in the form a + bi, where both a and b are real numbers. A complex number has two parts, the first part a is the real part of the complex number and the second part b is the imaginary part of the complex number. Also, i = √(-1), hence i² = -1.
Complex numbers can also be graphed on the complex plane.
√(-80) = √(-1) × √(80)
But since √(-1) = i
√(-80) = i × √80 = i × √16 × √5 = i × 4 × √5 = (4√5)i
√(-80) = (4√5)i

The number of quarters is 6 more than twice the number of dimes. There are a total of 276 coins in the bag. What is x, the number of dimes in the bag?
Answer:
There are 90 coins in the bag.
Step-by-step explanation:
Let [tex]x[/tex], [tex]y[/tex] the number of dimes and quarters. Now we proceed to translate each relevant sentence into mathematical expressions:
(i) The number of quarters is 6 more than twice the number of dimes:
[tex]y = 2\cdot x + 6[/tex] (1)
(ii) There are a total of 276 coins in the bag:
[tex]x + y = 276[/tex] (2)
By applying (1) in (2), we find that the number of dimes is:
[tex]x+2\cdot x + 6 = 276[/tex]
[tex]3\cdot x = 270[/tex]
[tex]x = 90[/tex]

I WILL GIVE BRAINLIEST IF CORRECT The area of a square is 49 square centimeters. Find the length of a side. Find the length of the
diagonal
Answer: 7
Step-by-step explanation:
Since squares have the same side lengths
then you need to find a number that multiplies twice that equals 49
7*7 = 49
Answer: Length of a side: 7 / Length of the diagonal: 9.9
Explanation:
Just square root 49, so it becomes 7. That's the side length. In order, to find the diagonal of the square, just use Pythagorean Theorem, a^2+b^2=c^2. Because it's a quadrilateral, all of the sides should equal 7. a^2 would be 7 and b^2 would be 7. 49+49=98. Square root 98 and you would get 9.899... That would be estimated to 9.9.

The ratio of John's earning to Musa's earning is 5:3. If Johns earning increases by 12% his new figure becomes 5,600. Find the corresponding percentage change in musa's earning if the sum of their new earning is 9,800.
Answer:
37.6%
Step-by-step explanation:
You can use find John's original earnings by taking 12% off of 5600. You can do this by doing 0.78 x 5600, and you get 4368.
Now, we can use John's orignal earning to find Musa's original earning. Knowing that their earning's correspond, you can use the proportion 5/3 = 5600/x. You can use cross products to solve:
4368 x 3 = 5x
13104 = 5x
2620.8 = x
Musa's original earnings was 2620.8.
If the sum of their new earnings is 9800, we can take of John's new earnings to find Musa's new earnings. 9800 - 5600= 4200. That means Musa's new earnings were 4200. To find the percentage, we can use the following equation, and then solve:
2620.8 = 4200x
.624 = x
That means that 2620.8 is 62.4% of 4200, and that it increased by 37.6%.

At the movie theater all snacks and all movie tickets are priced the same. Four snacks and three movie tickets cost $40. Two snacks and three movie tickets are $32. What is the cost of a snack and movie ticket?
Write a systems that could be used to solve this problem. Let x = the cost of a snack in dollars and let y = the cost of a movie ticket.
We know that four snacks and three movie tickets cost $40 dollars, and when you take away 2 snacks but still keep the tickets, its $32.
2 snacks= $8
What i did to find the cost of each ticket is I divided 8 by 2 (8/2) and ended getting $4
1 snack= $4
Now to find the cost of each ticket, i divided 2 snacks ($8) and got this equation:
32 - 8= 24
3 tickets= $24
Now to find the amount for each ticket, i divided 24 by 3 (24/3) and got the answer:
1 ticket= $8
Therefore, snacks are $4 and movie tickets are $8
x tickets= 8x
x snacks= 4x

Answer:
13. 23 boat rides; 22 are full, and the first one has 301 passengers.
12. $11,067.50
Step-by-step explanation:
13,105 people in a day, divided by 582 per ride.
13,105/582 = 22 (with a remainder)
582 x 22 = 12,804
So, the remainder is
13,105 - 12,804 = 301
23 rides, with 22 full and the first one having 301 people.

Consider the polynomial function p(x)= -9x^9 +6x^6 -3x^3 +1.
What is the end behavior of the graph of p?
Answer:
The end behavior of the graph of p is:
f(x) → ∞ as x → -∞ and f(x) → -∞ as x → ∞
Step-by-step explanation:
Given the polynomial function
[tex]p\left(x\right)=\:-9x^9\:+6x^6\:-3x^3\:+1[/tex]
Since the leading term of the polynomial (the term in a polynomial that contains the highest power of the variable) is -9x⁹, then the degree is 9 i.e. odd, and the leading coefficient is -9, i.e. negative.
This means that f(x) → ∞ as x → -∞ and f(x) → -∞ as x → ∞
The graph is also attached below.
Thus, the end behavior of the graph of p is:
f(x) → ∞ as x → -∞ and f(x) → -∞ as x → ∞

You and your friend walk to school together every day. You meet at the halfway point between your houses first and then walk to school. Each unit in the coordinate plane corresponds to 50 yards. A) What are the coordinates of the midpoint of the line segment joining the two houses? B) What is the distance that the two of you walk together?
Please show the steps
Answer:
no se
Step-by-step explanation:
The coordinate of the midpoint joining the two houses, since each unit on the coordinate is 50 units is (150, 250) and the distance walked to school is 254.95 yards
From the graph given :
The x - coordinate of the midpoint is 3 units from the origin = (3 × 50) = 150 yards
The y-coordinate of the midpoint is 5 units from the origin = (5 × 50) = 250 yards
Hence, the coordinate of the midpoint is (150, 250)
The distance walked to school :
Distance = √(y2 - y1)² + (x2 - x1)²
Distance = √(400 - 150)² + (300 - 250)²
Distance = √250² + 50²
Distance = 254.95 yards
Therefore, the distance the boys walk to school is 254.95 yards.
