a.) The color of Aqueous solution turns light green from blue, due to formation of iron sulphate .
b.) The color of the Aqueous solution turns colorless from blue due to formation of zinc sulphate.
2. Bells used in temples aren't made up of wood because wood isn't sonorous and hence can't produce ringing sound, and hence metals are used in making bells.
3. phosphorous is kept in water because it is highly reactive and reacts vigorously with air if left free in atmosphere .
4.
a.) CuSO4 + Mg =》MgSO4 + Cu
this is a single displacement reaction, where Magnesium being more reactive than Copper, displaces copper from its compound (copper sulphate) to form magnesium sulphate.
b. H2SO4 + Zn =》ZnSO4 + H2
this is a single displacement reaction,
where Zinc being more reactive than

A farmer sells 8.6 kg of Pierce an apple at the Farmers Market two fifths of the wait is pears and the rest is apples how many kilograms of apples did she sell at the Farmers Market
Answer:
Weight of Pears = 3.44 Kgs
Weight of Apple = 5.16 Kgs
Step-by-step explanation:
Given
The total weight of the Pears and the apple is 8.6 Kg
Out of this total weight, the weight of the pears is 2/5
Hence, weight of the Pears is 2/5 * 8.6 = 3.44 Kg
Weight of the Apple is equal to 8.6 -3.44 Kgs = 5.16 Kgs
Weight of Pears = 3.44 Kgs
Weight of Apple = 5.16 Kgs

Pls help I will do anything
Answer:
The probability of spinning red is [tex]\frac{1}{3}[/tex], the probability of spinning a 1 is [tex]\frac{1}{6}[/tex], the probability of spinning an odd number is [tex]\frac{1}{2}[/tex], and the probability of spinning a 9 is 0.
Step-by-step explanation:
Since there are a total of 6 possible outcomes, you can use this in the following questions. There are 2 red tiles, so the probability of spinning red is [tex]\frac{2}{6}[/tex] or [tex]\frac{1}{3}[/tex]. Since there are only one 1 tile, the probability of spinning a 1 is [tex]\frac{1}{6}[/tex]. Since there are three odd numbers, the probability of spinning an odd number is [tex]\frac{1}{2}[/tex]. Since there are no 9 in the spinner, the probability of spinning a 9 is 0 or never.
Find the measure of a.
Answer:
Step-by-step explanation:
The best way to measure an angle is to use a protractor. To do this, you'll start by lining up one ray along the 0-degree line on the protractor. Then, line up the vertex with the midpoint of the protractor. Follow the second ray to determine the angle's measurement to the nearest degree.

I kept getting 6 but the only option is -6 :/
Step-by-step explanation:
[tex]9 - \frac{x}{5} = 3 \\ 9 - 5 \times \frac{x}{5} = 3 \times 5 \\ 9 - x = 15 \\ - 9 - x = - 9 + 15 \\ - x = 6 \\ - x \div - 1 = 6 \div - 1 \\ x = - 6[/tex]
Answer:
Yeah the answer is -6
Step-by-step explanation:
9-x/ 5= 3
9-x = 15 (5 times three)
-x = 6 (9-6)
x= -6 ( a variable can never Be negative, but we have to give the minus to 6)

The area of the shaded sector is shown. Find the radius of circle M. Round your answer to the nearest hundredth.
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete, as the sector, its area and the angle at the center are not given.
I will solve this using the following illusration
The area of a sector is:
[tex]Area= \frac{\theta}{360} * \pi r^2[/tex]
Assume that:
[tex]\theta = 120[/tex]
[tex]Area = 20[/tex]
The equation becomes
[tex]20= \frac{120}{360} * \pi r^2[/tex]
Simplify
[tex]20= \frac{1}{3} * \pi r^2[/tex]
Take: [tex]\pi = 3.14[/tex]
[tex]20= \frac{1}{3} *3.14* r^2[/tex]
Cross Multiply
[tex]3.14 * r^2 = 20 * 3\\[/tex]
Solve for [tex]r^2[/tex]
[tex]r^2 = \frac{20 * 3}{3.14}[/tex]
[tex]r^2 = 19.11[/tex]
Take square roots
[tex]r = \sqrt{19.11[/tex]
[tex]r = 4.4[/tex]
The radius of the sector of a circle whose area is 20 square units and angle subtends at the center of 120° is 4.4 units.
What is a circle?It is a locus of a point drawn equidistant from the center. The distance from the center to the circumference is called the radius of the circle.
The angle subtends at the center is 120 degrees.
The area of the circle is 20 units.
We know that the area of a circle is given as
[tex]\rm Area = \dfrac{\theta }{360} \pi r^2[/tex]
Then we have the radius of the sector will be
[tex]\rm r = \sqrt{\dfrac{360*20}{120*\pi}}\\\\\\r = 4.37 \approx 4.4[/tex]
The radius of the sector is 4.4 units.

NG
No
Show result
Please help
Answer:
x =-16
Step-by-step explanation:
Given the equation
-3x - 21 = 27
We are to find the next step in solving the equation
Step 1: Add 21 to both sides
-3x - 21 + 21 = 27 + 21
-3x = 48
Step 2: Divide both sides by -3
-3x/3 = 48/3
-x = 16
x = -16
Hence the value of x is -16
Jack is selling used computers. he is paid $15/h plus a 5% commission on sales. What dollar amount of computer sales must jack make to earn $1000 in a 40-h work week.
Answer:
8000
Step-by-step explanation:
Jack sold worth $8000 computer sales in the last week.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, Jack is selling used computers. He is paid $15/h plus a 5% commission on sales.
He made $1000 in a 40-h week,
∴ He made $(15×40) = $600 for his work hours and $(1000 - 600)
= $400.
So, $400 dollars in 5% of the total sales and assuming he made a sell of $x.
∴ (5/100)×x = 400.
0.05x = 400.
x = 400/0.05.
x = 8000.
