9514 1404 393

Answer:

  {2, 2i, -2, -2i}

Step-by-step explanation:

Fourth roots of positive real numbers are always on the cardinal points of the complex plane. The positive real fourth root of 16 = 2^4 is 2. The others are this multiplied by various powers of i.

  2, 2i, -2, -2i

Answer:

The music director can form a total of 15 groups

6 Sixth grade students per group

5 Seventh grade students per group

Step-by-step explanation:

Sixth grade students = 90

Seventh grade students = 75

Find the highest common factor of 75 and 90

90 = 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90.

75 = 1, 3, 5, 15, 25, 75

The highest common factor of 75 and 90 is 15

Therefore, the music director can form a total of 15 groups

Sixth grade students per group = 90 / 15

= 6 Sixth grade students per group

Seventh grade students per group = 75 / 15

= 5 Seventh grade students per group

Answer:

Seven candy bars.

Explanation:

Suppose the number of candy bars purchased is x

The questions say he bought A magazine, means one magazine

the equation is:

4x + 5 = 33

4x = 33 – 5

4x = 28

x = 7

Kim bought 7 candy bars.

Answer:

20

Step-by-step explanation:

50%=10

100%=20

Answer:

20

Step-by-step explanation:

50% basically means half, so if 10 is 50% then the other 50% is also 10.

so 10x2=20

Answer:

Step-by-step explanation:

1. Rectangle: This is because all the angles are at right angles and the length is more than the breadth.

Area = Length X breadth = 6m X 5.1 m =30.6 metre square

2. Kite: it has two equal pairs of sides adjacent to each other

Area =(BD X CE )/2 = (8 X 12) /2 = 48

3. Parallelogram: This is because it has two opposite sides that are parallel, and the angles are not 90 degrees.

Area = base X height = 5.7 X 8 = 45.6 metres square

4. Rectangle: This is because all the angles are at right angles and the length is more than the breadth.

Area = Length X breadth = 2 yd X 3.1 yd = 6.2 square yards

5. Trapezium: it has only one pair of sides parallel.

Area = 0.5 ( top side + bottom side ) X height = 0.5 (6+3 X 5) = 22.5

6. Kite: it has two equal pairs of sides adjacent to each other

Area =(EG X FH)/2 = (10 X 7) /2 = 35

Answer: 33.6 feet

Step-by-step explanation:

Since the small rectangle has a width of 4 feet and a length of 10 feet. It simply means that the length is 2.5 times the width.

A larger, similar rectangle has a length of 12 feet. The width will be:

= 12 / 2.5

= 4.8 feet

The perimeter of the larger rectangle will then be:

= 2(Length + Width)

= 2(12 + 4.8)

= 2 × 16.8

= 33.6 feet

Answer:

28 miles

Step-by-step explanation:

Since 1 inch represents 14 miles, we can find the actual distance by multiplying 14 by 2:

14(2)

= 28

So, the real cities are 28 miles apart.

Answer:

Let the unknown distance be x

[tex] \tt \dfrac{1}{14} = \dfrac{2}{x} [/tex]

By cross multiplication

[tex] \tt \: 14 \times 2 = 1 \times x[/tex]

[tex] \tt \: 28 = x[/tex]

The far apart distance will be 28 miles.

Answer:

r=√(3v)/(xh)

Step-by-step explanation:

the volume of a cone is given as

v= 1/3 xr^2 h. Then we need the radius, r, of the cone

v= 1/3 xr^2 h

Let us cross multiply we have

3v= xr^2h

Make r^2 subject of the formula we have

r^2= 3v/xh

Find the square root of bother sides we have

r=√(3v)/(xh)

the radius, r, of the cone can be expressed as r=√(3v)/(xh)

Answer:

343 cube meters of air

Answer:

(-4, 5)

Step-by-step explanation:

partitions 1 to 4 means that point will make part of the line where it is 1 part to the other 4 parts. This means there are a total of five parts.

For x, we go from -7 to 8 or 15 units, and we are 1/5 of that distance so 3 units, add that to -7 we get -4.

For y, we go from 8 to -7, or 15 units, and we are 1/5 of that distance so 3 units, subtract that from 8 we get 5.

Answer:

The correct answer is:

c. Time is an exponent while the other units are factors.

Explanation:

In the compound interest formula, time is the exponent.

Since it is the exponent, this tells us how many times the base is multiplied by itself.  As such, it has a larger effect on the answer than any other piece of the equation.

Answer:

22

Step-by-step explanation:

3.56 = 4

5.9 = 6

12.087 = 12

4+6+12 = 22

Answer:

No.

Explanation:

4/10 cannot be simplified to 1/4. 4/10 is simplified to 2/5.

The decimal form is 0.4

Hopefully this is correct. Good luck with your studies.

4/10 = 2/5 which is not simplify to 1/4

so the answer is NO.

The answer is letter b. $4.20 / 60 ounce is the rate for the glass bottle while $3.06 / 51 ounces is the rate for the plastic one. Simplified, the glass bottle is $0.07 / ounce while the plastic bottle is $0.06 / ounce.
