What percentage of this 100 square grid is shaded ?

Answer:

2/5

Step-by-step explanation:

Use the distance formula to determine the distance between two points.

Answer:

The distance is

3√10  or about 9.49 (rounded to nearest hundredth's place).

Step-by-step explanation:

The distance is

3

√

10

or about

9.49

(rounded to nearest hundredth's place).

Explanation:

The formula for the distance for 3-dimensional coordinates is similar or 2-dimensional; it is:

d

=

√

+

(

y

−

y

1

)

2

+

(

z

2

−

z

)

2

We have the two coordinates, so we can plug in the values for

x

,

y

, and

z

:

d

=

√

(I wasn't sure if the

3

−

meant

3

or

−

, so I assumed it was

−

)

Now we simplify:

d

d=√90

d=3√10

If you want to leave it in exact form, you can leave the distance as

3√10

. However, if you want the decimal answer, here it is rounded to the nearest hundredth's place:

d≈9.49

Hope this helps!

Rational numbers are any of the following:

Irrational numbers are thus defined as:

This means that -8.7 is not irrational, as it is not an unending, non-repeating number: an easy way to remember how to answer this is to look at whether the number has been expressed in decimal form if it has (unless you have been told that it has been rounded) it must be rational, as it can be written as a decimal number.

Answer:

32

Step-by-step explanation:

The length of AC as per he sine of an angle is 32.

The sine of an angle is the ratio of the height and the hypotenuse of the triangle.

Given, ∠C = 30°

AB = 16

Therefore, sin ∠C = (AB/AC)

Therefore, sin (30°) = 16/AC

⇒ (1/2) = 16/AC

⇒ AC = 2 × 16

⇒ AC = 32

Answer:

he would have to pay $60

Step-by-step explanation:

The price of jeans that Jaiden has to pay after the discount will be equal to $60.

The Latin phrase "per centum," which means "by the hundred," is where the English word "percentage" comes from. Percentage segments are those with a numerator of 100. In other words, it is a connection where the whole is always deemed to be valued 100.

As per the given information in the question,

Original price of jeans = $80

Percentage discount on sale = 25%

Then, the discount of price on the jeans will be,

80 × 25/100 = $20

Then, the price of jeans after the discount will be,

$80 - $20 = $60

Answer:

Kindly check explanation

Step-by-step explanation:

Given the model:

s = 10│x - 4│+ 50

s represents the sound level in decibels and x represents the number of measures of music played

To find x at s = 80

The equation becomes /

80 = 10│x - 4│+ 50

Subtract 50 from both sides of the equation

80 - 50 = 10 |x - 4| + 50 - 50

30 = 10 | x - 4 |

Divide both sides by 10

30/10 = 10|x - 4| / 10

3 = |x - 4|

|x - 4| is an absolute value expression

±3 = |x - 4|

x = 3 + 4 = 7

x = - 3 + 4 = 1

Answer:

f(1) = 16

Domain: 0 ≤ t ≤ 2

Step-by-step explanation:

Given

f(t) = -16t²+ 32t

Solving (a): f(1)

Substitute 1 for t in f(t)

f(t) =− 16t²+ 32t .

f(1) =− 16 * (1)²+ 32 * 1

f(1) = -16 * 1 + 32

f(1) = -16 + 32

f(1) = 16

Solving (b): The domain

The implication of the given parameter in (b) is that t ≤ 2.

Since t represents time, t can't be negative.

Hence, a reasonable domain is

0 ≤ t ≤ 2

Answer:

Friend A pays $340 and friend B pays $510

Step-by-step explanation:

Let's call

x: payment of friend A

1.5x: payment of friend B

The sum of both payments must total $850, thus:

x + 1.5x = 850

Simplifying:

2.5x=850

x = 340

Now for friend B:

1.5x=1.5*340=510

Friend A pays $340 and friend B pays $510

To find the area it is A=1/2bh (base times height times 1/2)

A=1/2(15)(8)

A=1/2(120)

A=60
