Answer:
45g
Step-by-step explanation:
The amount of salt left once the whole water is evaporated can be calculated as follows
= 12% × 375
= 12/100 × 375
= 0.12×375
= 45
Hence 45g of salt is left after the evaporation of water

What is the value of x?
Answer:
45°
Step-by-step explanation:
80 + 55=135
Every type of triangle has 180 degrees.
180-135=45 degrees.
m∠A = (2x + 5)° and m∠B = (3x − 15)°.
Find the measure of each angle (in degrees) of ▱ABCD.
Answer:
Step-by-step explanation:
We have to assume that ABCD is a parallelogram. If it isn't, leave a note.
Secondly we have to assume that the angles are consecutive. In a parallelogram, consecutive angles are supplementary.
<A + <B = 180
2x + 5 + 3x - 15 = 180
5x - 10 = 180 Add 10 to both sides
5x = 190 Divide by 5
x = 190/5
x = 38
A = 2x + 5
A = 2*38 + 5
A = 81
B = 3x - 15
B = 3*38 - 15
B = 99

Step-by-step explanation:
The digit "9" is in the ten's place because it is two numbers/spaces left from the decimal. If you make all the other digits "0", you'll be left with a value of 90.
The digit "1" is in the one's place because it is one number/space left from the decimal. Applying the same concept of making all the other digits "0", you'll be left with a value of 1.
The type of digits to the right of the decimal, starting from left to right, are the tenths place, hundredths place, thousandths place, ten-thousandths place, and millionths. Remember and know those digit types based on their position away from the decimal. The value will be there for you to see afterward.
When the focus and directrix are used to derive the equation of a parabola, two distances were set equal to each other. = StartRoot (x minus x) squared + (y minus (negative p)) squared EndRoot = StartRoot (x minus 0) squared + (y minus p) squared EndRoot The distance between the directrix and is set equal to the distance between the and the same point on the parabola.
Answer:
The answer is "A point on the parabola and Focus".
Step-by-step explanation:
[tex]= \sqrt{(x - x)^2 + (y- (-p))^2} = \sqrt{(x-0)^2+ (y-p)^2} \\\\= \sqrt{(0)^2 + (y+p))^2} = \sqrt{(x)^2+ (y-p)^2} \\\\= \sqrt{(y+p))^2} = \sqrt{(x)^2+ (y-p)^2} \\\\= (y+p) = (x)+ (y-p) \\\\= y+p = x+ y-p \\\\=2p=x\\\\=x=2p[/tex]
Whenever the focus and also the guideline are utilized in determining the parabolic formula, two distances have indeed been equal.
The distance from the direction, as well as a parabolic point, was equal to the distance from the center to a parabolic point.
Answer:
The distance between the directrix and a point on the parabola is set equal to the distance between the focus and the same point on the parabola.

Rewrite the expression in the picture in the form k times x^n.
Answer:
8 x^-2
Step-by-step explanation:
2 sqrt(x) * 4x ^ -5/2
Rewriting
2 x^1/2 * 4x ^ -5/2
2*4 = 8
x^1/2 * x^ -5/2

Mrs.Click has a strawberry patch in her garden. It's border is 4/5 meters wide and 3/2 meters long. What is the area of Mrs.Clicks Garden?
Answer
Mrs. Click's Garden is 6/5 or 1 1/5 square meters.
Explanation
Mrs. Click's has a rectangular garden. To find the area of a rectangle, you multiply the width by the length. To find the area of Mrs. Click's Garden, you multiply 4/5 by 3/2.
To multiply fractions, you multiply the numerator by the denominator.
4×3 is 12 and 5×2 is 10. You get the fraction 12/10, which can be simplified to 6/5, or 1 1/5.

A number is divided by 1/4.Write an expression for this situation.
Answer:
x ÷ 1/4
Step-by-step explanation:
Concepts:
An expression a mathematical sentence that has at least two numbers and a minimum of one math operation (addition, subtraction, etc.) in it. An expression cannot have an = sign in it.A variable is an unknown, numerical value in an equation, often represented by the letter x.Solving:
Let's translate the first part of the expression:
1. "A number"
Since we're unaware of the number in this expression, we can mark it as a variable, x.This means that, so far for our expression, we only have the variable, "x".2. "divided by 1/4"
When we're dividing, we use the ÷ symbol to represent that operation. Now, let's put the first part of our expression with the second one: "x ÷ 1/4"Therefore, the expression for this situation is x ÷ 1/4.
mary has 17 m of rope. She wishes to cut it in three pieces so that she has 3 m more than amanda, and amanda has 2 m less than Sarah.
Answer:
Length of Sarah rope = 6 m
Length of Amanda's rope = 4 m
Length of Mary's rope = 7 m
Step-by-step explanation:
Let the length of Sarah rope = x
Length of Amanda's rope= x - 2
Length of Mary's rope = (x - 2 ) + 3 = x - 2 + 3 = x + 1
Length of rope = 17 m
x + x - 2 + x + 1 = 17
Combine like terms
x + x + x - 2 + 1 = 17
3x - 1 = 17
Add 1 to both sides
3x = 17 + 1
3x = 18
Divide both sides by 3
x = 18/3
x = 6
Length of Sarah rope = x = 6 m
Length of Amanda's rope= x - 2 = 6 - 2 = 4 m
Length of Mary's rope = x + 1 = 6 + 1 = 7 m
Can you guys help me find ST on the left and WY on the right
Answer:
ST = 17 and WY = 32
Step-by-step explanation:
3
SV is a perpendicular bisector and divides Δ RST into 2 congruent triangles with
ST = SR , that is
7x - 4 = 3x + 8 ( subtract 3x from both sides )
4x - 4 = 8 ( add 4 to both sides )
4x = 12 ( divide both sides by 4 )
x = 3
Then
ST = 7x - 4 = 7(3) - 4 = 21 - 4 = 17
-------------------------------------------------------------------
4
Δ WXY and Δ WXZ are congruent ( both have 3 congruent angles ), then
WZ = WY , that is
9x - 13 = 6x + 2 ( subtract 6x from both sides )
3x - 13 = 2 ( add 13 to both sides )
3x = 15 ( divide both sides by 3 )
x = 5
Then
WY = 6x + 2 = 6(5) + 2 = 30 + 2 = 32

What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
2x² + 7x + 6x² + x - 64x² - 9x² - 5x + 6
Combine all like terms.
(2x² + 6x² - 64x² - 9x²) + (7x - 5x) + 6
(8x² - 73x²) + 2x + 6
-65x² + 2x + 6
There are no common factors or like-terms to simplify.
So,
The simplified form is -65x² + 2x + 6
Thus,
The simplified form of the complex expression 2x² + 7x + 6x² + x - 64x² - 9x² - 5x + 6 is

If two triangles have three congruent, corresponding angles, what additional information is needed to prove that the triangles are congruent?
Answer:
one side length has to be equal in both triangles.
Answer:
To prove that two triangles with three congruent, corresponding angles are congruent, you would need to have at least one set of corresponding sides that are also congruent. You could then use ASA or AAS congruence theorems or rigid transformations to prove congruence.

Answer:
31 degrees
Step-by-step explanation:
the side with the length of 29 can be seen as the radius of a circle.
and the sin value of an angle is the distance of a point on that circle from the x-axis. as the standard sin function is for the standard circle with radius 1, we need to multiply this by the actual radius.
15 = sin(?)×29
sin(?) = 15/29 = 0.5172...

Answer:
3.8; 4
Step-by-step explanation:
In this exercise, you're are required to find the missing values by performing some arithmetic calculations.
For the first part;
Let the missing value be X
Translating the word problem into an algebraic expression, we have;
[tex] X = 2000 * 1.9 * 10^{-6} [/tex]
[tex] X = 3.8 * 10^{-3} [/tex]
For the second part;
Let the missing value be Y.
[tex] 3.8 * 10^{-3} = Y * 9.5 * 10^{-4} [/tex]
[tex] X = \frac {3.8 * 10^{-3}}{9.5 * 10^{-4}} [/tex]
[tex] X = 4 [/tex]
Therefore, the complete sentence would be written as follows;
[tex] 3.8 * 10^{-3} [/tex] is 2000 times greater than [tex] 1.9 * 10^{-6} [/tex]. It is also 4 times greater than [tex] 9.5 * 10^{-4} [/tex]
