Rewrite 21/300 as a decimal.
The complement of 17% is
Answer:
73%.
Step-by-step explanation:
Let x be the complement of 17%.
We are asked to find the complement of 17%.
We know that two angles are complementary when they add up-to 90 degrees. So we can set an equation as:
[tex]17\%+x=90\%[/tex]
[tex]17\%-17\%+x=90\%-17\%[/tex]
[tex]17\%-17\%+x=73\%[/tex]
Therefore, the complement of 17% is 73%.
What is the molar solubility of magnesium fluoride in a solution that is 0.40 m f− ions? the ksp of mgf2 is 6.4 × 10−9. hints what is the molar solubility of magnesium fluoride in a solution that is ions? the of is . 8.0 × 10−9 8.0 × 10−5 1.6 × 10−8 4.0 × 10−8?
The molar solubility of magnesium fluoride in a solution with a concentration of 0.40 M fluoride ions is 0.80 M.
Explanation:The molar solubility of magnesium fluoride in a solution with a concentration of 0.40 M fluoride ions can be calculated using the solubility product constant (Ksp) of MgF2, which is 6.4 × 10-9.
First, write the dissolution equation for MgF2: MgF2(s) ⇌ Mg2+(aq) + 2F-(aq)
Since the stoichiometry of the dissolution equation is 1:2 between magnesium ions and fluoride ions, the molar solubility of MgF2 is twice the concentration of fluoride ions.
Therefore, the molar solubility of MgF2 in a solution that is 0.40 M fluoride ions is 2 × 0.40 M = 0.80 M.

Christina can paint 420 square feet in 105 minutes. Which unit rate describes the scenario?
4 square feet per minute
square foot per minute
1 square foot per 4 minutes
1 square foot per minute
divide total sq ft x total minutes to get square feet per minute
420/105 = 4
so 4 sq ft per minute

A hair salon charges fixed rate of $25.00 for a haircut and then an additional $15.00 for any other services. Write a function to model cost of services there and then determine how many services you had if you were charged for $115.00
Answer:
f(x) = 15x + 25; f(6) = 115
Step-by-step explanation:
the flat rate of $25 will be the y-intercept and the slope will be $15. since u are charged $115, plug that in for f(x) and solve for x. so the right answer is
f(x) = 15x + 25; f(6) = 115

what is the exact of the expressions square root of 180 - square root of 125 + square root of 5
The exact value of the expression √180 - √125 + √5 simplifies to 2√5, by combining like terms after simplifying each square root separately.
The exact value of the expression [tex]\sqrt{180}[/tex] - [tex]\sqrt{125}[/tex] + [tex]\sqrt{5}[/tex] can be calculated by simplifying each square root separately. Firstly, the [tex]\sqrt{180}[/tex] can be simplified to 6√5, because 180 = 36 × 5, and 36 is a perfect square whose square root is 6. Similarly, the [tex]\sqrt{125}[/tex] simplifies to 5√5, since 125 = 25 × 5 and the [tex]\sqrt{25}[/tex] is 5. The [tex]\sqrt{5}[/tex] remains as it is because it cannot be simplified further.
The expression then becomes 6√5 - 5√5 + √5. Now, we combine like terms. Since all terms involve the [tex]\sqrt{5}[/tex], we can combine them as follows: (6 - 5 + 1)√5, which simplifies to 2√5. Therefore, the exact value of the expression is 2√5.

Each package of dried fruit contains 3/16 of a pound Mr. Lopez has 4 pounds of dried fruit How many packages can he fill
Final answer:
Mr. Lopez can fill 21 full packages of dried fruit, each containing 3/16 of a pound, with his 4 pounds of dried fruit.
Explanation:
The question asks how many packages of dried fruit Mr. Lopez can fill if each package contains 3/16 of a pound and he has 4 pounds of dried fruit. To answer this, we need to perform a division to find out how many 3/16 are in 4 pounds.
To solve this, we divide 4 pounds by 3/16 pounds per package:
4 ÷ (3/16) = (4/1) ÷ (3/16) = (4 × 16) / 3 = 64/3 = 21 with remainder 1.
Therefore, Mr. Lopez can fill 21 full packages of dried fruit and will have a little left over which is not enough to fill an additional full package.

Which of these is equivalent to 3-23-2?
Answer:
-22
Step-by-step explanation:
This is a case of directed numbers. The numbers 23 and 2 carry negative signs like this:
- 23
- 2
Therefore, adding these negative numbers gives -23 - 2 = -25
Adding the sum to 3 gives: 3 - 25 = -22

(4-2)^3 -3*4 =
(4-2) = 2, 2^3 = 8
3*4 =12
so you have 8-12 = -4
Answer is -4
Explanation:
This question's it's about the order of operations. It stands for parenthesis, exponents, multiply, divide, add, and subtract. It can also go left too right. (PEMDAS)
First, do parenthesis.
[tex](4-2)=2[/tex]
[tex]2^3-3*4[/tex]
Then exponents.
[tex]2^3=2*2*2=8[/tex]
[tex]8-3*4[/tex]
Multiply left to right.
[tex]3*4=12[/tex]
Subtract left to right.
[tex]8-12[/tex]
[tex]12-8=4[/tex]
It change positive to negative sign.
Answer: → [tex]\boxed{=-4}[/tex]
*The answer must have a negative sign.*

A surveyor took the following measurements from two irregularly shaped pieces of land. Some of the lengths and angle measures are missing. Find all missing lengths and angle measures. Round lengths to the nearest tenth and angle measures to the nearest minute
To find the width of the river, use trigonometry and the tangent function. The width of the river is approximately 67.1 meters.
Explanation:To find the width of the river, we can use trigonometry. The surveyor measured an angle of 35° from the baseline to the tree on the opposite bank. We know the distance along the river is 100 m. Let's denote the width of the river as 'x'.
We can use the tangent function to solve for 'x'. The tangent of the angle is equal to the opposite side divided by the adjacent side. In this case, the opposite side is 'x' (the width of the river) and the adjacent side is 100 m (the distance along the river).
So, the equation becomes:
tan(35°) = x/100
To find the value of 'x', we can multiply both sides by 100:
x = 100 * tan(35°)
Using a calculator, we can find that x is approximately 67.1 m. Therefore, the width of the river is approximately 67.1 meters.

Cell phones can weigh as little as 2 ounces. How many pounds can the cell phone weigh?
A cell phone weighing 2 ounces translates to 0.125 pounds, since there are 16 ounces in one pound.
Explanation:Cell phones can weigh as little as 2 ounces. The first step in determining how much a cell phone can weigh in pounds is to know the conversion factor between ounces and pounds. Since there are 16 ounces in one pound, you can divide the weight of the cell phone in ounces by 16 to convert it to pounds. For a cell phone that weighs 2 ounces:
Divide the weight in ounces by 16 to convert to pounds: 2 ounces ÷ 16 = 0.125 pounds.Therefore, a cell phone that weighs 2 ounces is equivalent to 0.125 pounds.
