Ratio of A to B is 7:5...

so if there was 295 mL of compound B...
7 / 5 = a / 295
cross multiply
(5)(a) = (295)(7)
5a = 2065
a = 2065/5
a = 413 .... so 413 mL of compound A would be used

for a total solution of (295 + 413) = 708 mL solution <===

If f(x) = 3x + 2 and g(x) = 2x – 2, what is (f – g)(x)? A. x + 4 B. x – 2 C. x D. 5x – 2 E. x – 4
Bond [772]

Answer: Option A

Step-by-step explanation:

Given the functions f(x) and g(x):

f(x) = 3x + 2

g(x)=2x-2

(f-g)(x) indicates that you need to subtract the function f(x) = 3x + 2 and the function g(x)=2x-2.

Then:

(f-g)(x)=3x + 2-(2x-2)

Now, you need to dstribute the negative sign and then you have to add like terms. Then:

(f-g)(x)=3x + 2-2x+2\\\\(f-g)(x)=x+4

You can observe that this answer matches with the option A.

Mira finished 2/5 of a puzzle in 1/ 5 of an hour. At this rate, how many puzzles could she finish in 1 hour
Romashka-Z-Leto [24]
If the puzzle was solved in 1/5 hour, we can multiply the time it took to solve one puzzle by 5.

2/5(5/1)
=10/5
=2

So she'll be able to solve 2 puzzles in one hour.

Kit and Kat are building a kite for the big kite festival. Kit has already
Lunna [17]

Kat should tell Kim that It's too late to change the area of this kite because the length of the diagonals of a kite determines its area.

<h3>How to calculate the area of a kite?</h3>

In Mathematics, the area of a kite is equal to one-half the product of the length of its diagonals. Mathematically, the area of a kite can be calculated by using this formula:

A = ½ × d₁ × d₂

<u>Where:</u>

  • A is the area of a kite.
  • d₁ and d₂ are the length of the diagonals of a kite.

Since Kit has already cut his sticks for the diagonals, Kat should tell him that it's too late to change the area of this kite because the length of the diagonals of a kite determines its area.

Simplify the expression the root of negative one all over the quantity of four minus three i minus the quantity of two plus five
svlad2 [7]
We will break this down into its parts:
We know that this is a fraction where the numerator is √(-1) = i
The denominator:
4 - 3i - (2 + 5i); we put 2 + 5i in brackets because we are to subtract its quantity.
Simplifying the denominator:
4 - 3i - 2 - 5i
= 2 - 8i
Now, we write the expression in fractional form:
i / (2 - 8i)
To remove an imaginary number from the denominator, we multiply and divide by its conjugate. The conjugate of a + bi is a - bi
i(2 + 8i) / (2² - (8i)²)
= (-8 + 2i) / (4 + 64)
= -2/17 + i/34
