Answer:

25% of 80 is D. 20kg

Step-by-step explanation:

50% of 80 is 40 and we know that 25% is half of 50%, so half of 40 would be 20.

So, the answer is D. 20kg

Answer:

C. Lines with arrows that point outward radiate from the charge in all

directions.

The statement which best describes the electric field around a positive charge is  Lines with arrows that point outward radiate from the charge in all directions, the correct option is C.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.

We are given that;

The four options

Now,

This is because the electric field at a point in space is in the direction of the force that the electric field would exert on a positive test charge if there were a positive test charge at that point in space1. Because positive charges repel each other, the electric field around an isolated positive charge is oriented radially outward.

Therefore, by unitary method the answer will be Lines with arrows that point outward radiate from the charge in all directions.

Answer:

The object travels 144,000,000 feet.

Step-by-step explanation:

The distance the object travel after t seconds is given by:

[tex]d(t) = 64t^2[/tex]

How far would the object travel after 1.5 * 10^3 seconds

This is d when [tex]t = 1.5 \times 10^3 = 1500[/tex], so [tex]d(1500)[/tex]

[tex]d(1500) = 64*1500^2 = 144000000[/tex]

The object travels 144,000,000 feet.

Answer:

[tex]x\leq 1.78[/tex]

Step-by-step explanation:

We are given that

Width of pool, b=4.5 m

We have to find the inequality which  represents the possible lengths of the wading pool.

Let x be the length of wading pool

We know that

Area of rectangle=[tex]length\times breadth[/tex]

According to question

Using the formula

[tex]4.5x\leq 8[/tex]

Divide by 4.5 on both sides we get

[tex]x\leq\frac{8}{4.5}[/tex]

[tex]x\leq 1.78[/tex]

Answer:

first method

subtract 5 from both side

2x + 5 -5 = 12 - 5

:. 2x = 7

:. X= 2

7

divide 2 from both side

X= 2x 7

2 2

:. X= 3.5

second method

2x = 12 - 5

2x = 7

X= 2 ÷ 7

:. X= 3.5

Answer: x=2.5

y=-1.75

Step-by-step explanation:

x-2y=6

x=6+2y

3(6+2y)+2y=4

18+6y+2y=4

8y=-14

y=-1.75

x=6+(-1.75)(2)

x=2.5

Answer: See explanation

Step-by-step explanation:

They are truly both right.

Maya says there are 4 hundreds in 5,467. This is right because the place value of 4 in 5467 is 4 hundreds = 400.

Jenny says there are 54 hundreds in 5,467. This is also correct as well. The number 5467 in words is five thousand four hundred and sixty seven. 54 hundreds equals = 54 × 100 = 5400

The place value of 5 is 5000.

The place value of 4 is 400

Addition of both gives = 5000 + 400 = 5400

If we divide 5400 by 100, we would have 54. It shows that there are 54 hundreds.

Both are correct

Answer:

percent error is 11.1%  (which agrees with answer B)

Step-by-step explanation:

The discrepancy (difference) between the measurement and the real length was: 5 - 4.5 = 0.5 ft

Then the percent difference is calculated as:

(difference / real value) * 100 = ( 0.5 / 4.5ft  ) * 100 =  11.1%
