Answer 1

Answer and Step-by-step explanation:

For these, you have to make sure the same amount of moles are on each side of the chemical equation.

[tex]1ZN + 2HCL[/tex] → [tex]1ZnCL_{2} + H_{2}[/tex]

[tex]1SiO_{2} + 4HF[/tex] → [tex]SiF_{4} + 2H_{2} O[/tex]

[tex]12HCIO_{4} + 1P_{4} O_{20}[/tex] → [tex]4H_{3}PO_{4} + 6Cl_{2} O_{7}[/tex]

These are the balanced equations.

The circumference of a circle is 6π ft. What is the area, in square feet? Express your answer in terms of
π

Please help

Answers

Answer:

Circumference of the circle 2π(radius)=6π ft

Therefore, radius=3 ft

Area=π(radius)²=π×3²=9π ft²

9π ft² is the right answer.

The area of circle is 9π square feet.

What is area?

Area is the amount of area occupied by an object's flat (2-D) surface or shape.

The circumference of circle = 2πr

6 = 2πr

r = 3π

And the area of circle is πr².

The area of the circle = 9π

Therefore, the area of the circle is 9π square feet.

Answer:

option 2

Step-by-step explanation:

Answer:

-2 2/3,   -2.5,   1.3,  1 1/2,   3

Step-by-step explanation:

So least to greatest

First we should look at the negatives

The smallest number is -2 2/3

The second smallest number is -2.5

The third smallest number is   1.3

The fourth smallest number is   1 1/2

The last number should be the biggest number which would be 3 in this problem

To make this easier you can convert all the fraction to decimal points too

-2 2/3 would be around -2.66

1 1/2 would be 1.5

Find the Area of the figure below, composed of a parallelogram and two semicircles. Round to the nearest tenths place.


See the picture


Please

Answers

Answer:

100.3

Step-by-step explanation:

Area of parallelogram = 10 * 5 = 50 (As to find the area of a parallelogram, you would need to multiply the height and base: just like a rectangle)

We now have to work out the area of the two semi-circles. Both semi-circles have the same diameter which is 8, which means the semi circles are of the same size. Therefore we would just need to work out the area of 1 semi-circle and apply it to the second semi-circle (if that makes sense).

Area of semi-circle = 1/2(πr2 ) --> The '2' is supposed to be squared of r

radius = 8/2 = 4

1/2 (π*4*4)

Put that in calculator and should equal = 8π (Area of 1 semi-circle)

Area of 2 semi-circles  = 8π + 8π = 16π

Total Area = (Area of parallelogram) + (Area of 2 semi-circles)

TA = 50 + 16π

Total Area (Nearest tenths place): 100.3

Hope this helps :)

Answer:

100.2 square units

Step-by-step explanation:

The figure comprises of two semicircles and a parallelogram.

The two semicircles add to one full circle.

Area of circle:

A = πr² A = 3.14*(8/2)² = 3.14*16 = 50.2 square units (rounded to the nearest tenth)

Area of parallelogram:

A = ah A = 10*5 = 50 square units

Total area is the sum of the two:

50.2 + 50 = 100.2 square units

Graph the inverse of the function, f (x) = ( x+ 2)^3-4

Answers

Answer:

The inverse of this function is:

[tex]f(x) = \sqrt[3]{x + 4} - 2[/tex]

Step-by-step explanation:

To find the inverse function, we can simply swap x and f(x) and solve for the latter:

[tex]x = (f(x) + 2)^3 - 4\\x + 4 = (f(x) + 2)^3\\\sqrt[3]{x + 4} = f(x) + 2\\f(x) = \sqrt[3]{x + 4} - 2[/tex]

A certain microprocessor requires either 2, 3, 4, 8, or 12 machine cycles to perform various operations. Twenty-five percent of its instructions require 2 machine cycles, 20% require 3 machine cycles, 17.5% require 4 machine cycles, 12.5% require 8 machine cycles, and 25% require 12 machine cycles. a) What is the average number of machine cycles per instruction for this microprocessor

Answers

Answer:

The average number of machine cycles per instruction for this microprocessor is 5.8.

Step-by-step explanation:

To find the average number of machine cycles per instruction for this microprocessor, we multiply each number of cycles for it's relative frequency.

We have that:

25% require 2 cycles.

20% require 3 cycles.

17.5% require 4 cycles.

12.5% require 8 cycles.

25% require 12 cycles.

So the average number is:

[tex]M = 0.25*2 + 0.2*3 + 0.175*4 + 0.125*8 + 0.25*12 = 5.8[/tex]

[tex]\displaystyle m\angle AED=32.5^\circ[/tex]

Step-by-step explanation:

Angles in a Circle

An exterior angle of a circle is an angle whose vertex is outside a circle and the sides of the angle are secants or tangents of the circle.

Segments AE and DE are secants of the given circle. They form an exterior angle called AED.

The measure of an exterior angle is equal to half the difference of the measure of their intercepted arcs.

Intercepted arcs in the given circle are AD=113° and BC=48°. The exterior angle is:

[tex]\displaystyle m\angle AED=\frac{AD-BC}{2}[/tex]

[tex]\displaystyle m\angle AED=\frac{113^\circ-48^\circ}{2}=\frac{65^\circ}{2}[/tex]
