Answer:

2√10

Step-by-step explanation:

Given the coordinates (-6, 2) and (0,0)

We are to find the distance between the coordinates. Using the distance formula;

d = √(x2-x1)²+(y2-y1)²

d = √(0-2)²+(0+6)²

d = √(-2)²+(6)²

d = √4+36

d = √40

d = √4*10

d = 2√10

Hence the required distance is 2√10

Answer:

The answer is 2/10 which simplifies to 1/5

Answer:

The length of the side VT is approximately 11.1 feet long.

Step-by-step explanation:

There is a trigonometry law called the law of sines, which states the sine of an angle divided by its opposite side is equivalent to the sine of all the other angles in that right triangle divided by its corresponding opposite side. You can use this law to help you solve for x. By applying the law of sines, you'll get that [tex]\frac{sin(90^{o})}{36} =\frac{sin(18^{o})}{x}[/tex] ⇒ [tex]\frac{36}{sin(90^{o})} = \frac{x}{sin(18^{o})}[/tex] ⇒ [tex]x=\frac{36*sin(18^o)}{sin(90^{o})}[/tex] ⇒ [tex]x=11.1ft.[/tex]

Answer:

The area of the paralellogram is 24 square units.

Step-by-step explanation:

Geometrically speaking, the area of the parallelogram has an equation equivalent to the area formula for a rectangle, that is:

[tex]A = b\cdot h[/tex] (1)

Where:

[tex]A[/tex] - Area.

[tex]b[/tex] - Base.

[tex]h[/tex] - Height.

The base and height of the parallelogram are, respectively:

Base

[tex]b = 8-2[/tex]

[tex]b = 6[/tex]

Height

[tex]h = 5-1[/tex]

[tex]h = 4[/tex]

Then, the area of the parallelogram is:

[tex]A = (6)\cdot (4)[/tex]

[tex]A = 24[/tex]

The area of the paralellogram is 24 square units.

Answer:

$135

Step-by-step explanation:

Step 1

Conversion

Base = 2 yards

1 yard = 3 feet

2 yards = x

Cross Multiply

x = 2 × 3 feet = 6 feet

Height = 5 yards

1 yard = 3 feet

5 yards = x

Cross Multiply

x = 5 × 3 feet = 15 feet

Step 2

Find the area of the triangle

Area of a triangle = 1/2 × base × height

Base = 6 feet

Height = 15 feet

Area = 1/2 × 6 × 15

= 45 square feet

Step 3

Find the cost of the carpet

1 Square foot = $3

45 square feet = x

Cross Multiply

x = 45 × $3

x = $135

Therefore, the amount you will pay to cover a triangular section of the floor is $135

Answer:

30

Step-by-step explanation:

Assuming your parallelogram looks like the one in the attached image.

The area of a parallelogram is base x height,  [tex]A=bh[/tex].

The base is 10; the height is 3, so A = 10 x 3 = 30.

Answer:

$6725

Step-by-step explanation:

Given data

Princiapal= $5000

Rate=2.3%

Time= 15years

The function that will model this situation is given as

A=P(1+rt)

The above function is a simple interest function

Substitute our data we can find the amount A

A=5000(1+0.023*15)

A= 5000(1+0.345)

A=5000(1.345)

A=5000*1.345

A=$6725

Hence the value of the investment after 15 years is $6725

Given:

Point = (1,-4), Slope - 8

Point = (1,5), Slope =1

To find:

The slope-intercept forms of the given lines.

Solution:

The slope intercept form of a line is:

[tex]y=mx+b[/tex]

The point slope form is:

[tex]y-y_1=m(x-x_1)[/tex]

where, m is the slope of the line.

We have, Point = (1,-4), Slope - 8. So, the equation of the line is:

[tex]y-(-4)=-8(x-1)[/tex]

[tex]y+4=-8x+8[/tex]

[tex]y=-8x+8-4[/tex]

[tex]y=-8x+4[/tex]

Therefore, the correct option is B.

We have, Point = (1,5), Slope =1. So, the equation of the line is:

[tex]y-5=1(x-1)[/tex]

[tex]y-5=x-1[/tex]

[tex]y=x-1+5[/tex]

[tex]y=x+4[/tex]

Therefore, the correct option is D.

Answer:

480

Step-by-step explanation:

I did the test and this is what it said in the review.

The new volume of the prism is 480 m³, option B is correct

A three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

The total surface area of the prism is given by:

2lw + 2lh + 2wh = 360

Dividing both sides by 2, we get:

lw + lh + wh = 180

The volume of the prism is given by:

lwh = 60

Multiplying both sides by 8, we get:

8lwh = 480

Substituting 2l, 2w, and 2h for l, w, and h, respectively, we get:

(2l)(2w)(2h) = 8lwh

(2l)(2w)(2h) = 480

Simplifying, we get:

(2l)(2w)(2h) = 8lwh

8lwh = 480

Therefore, the new volume of the prism is 480 m³, option B is correct

Answer:

Step-by-step explanation:

the distance between (3, -4) and (5, -4) is 2, and the distance between (3, -2) and (5, -2) is also 2. since its a quadrilateral do 2x2 and you get 4.

hello

the angles make up co-interior so the two would add up to 180º.

so we can set up a basic equation:

3x-10+5x-30=180

add like terms:

8x-40=180

add 40 to both sides:

8x=220

divide by 8

x=27.5º

Answer:

4 hours

Step-by-step explanation:

As she wants to keep two candles burning so after3 hours only 2 candles will remain and after 4 hours only one but till 4 hours 2 candles would be burning that what she wanted so its 4 hours

If Dora burns candles that burn for 4 and 5 hours, they combine to burn for 9 hours.

Combination and permutation are two alternative strategies for organizing elements of a set into subsets in mathematics. The subset's components can be recorded in any order when combined. The components of the subset are stated in a separate order in a permutation.

Dora has three candles that will burn for 3, 4, and 5 hours, respectively.

The combination of the hours of burning,

3 + 4 = 7 hours

4 + 5 = 9 hours

3 + 5 = 8 hours

So the greatest number is 9

Thus, if Dora burns candles that burn for 4 and 5 hours, they combine to burn for 9 hours.
