little help pls? its for a friend

Answer:

424 ft and 3 inches

Step-by-step explanation:

To calculate the diagonal of a square, multiply the length of the side by the square root of 2 --> d = a√2

a² + a² = diagonal²

diagonal = √(a² + a²) = √(2 x a²) which simplifies to diagonal = a√2

If area is given --> d = √(2*area)

Knowing square perimeter --> d = (perimeter/4)*√2

Answer:

The answer is 6 cm

Step-by-step explanation:

Now,

Radius = Diameter ÷ 2

R = 12/2 = 6 cm

Thus, The radius of the circle is 6 cm.

The measure for x is 30 degree.

A linear pair is a pair of adjacent angles formed when two lines intersect. The two angles of a linear pair are always supplementary, which means their measures add up to 180 degrees.

Given:

We have angles forms line are x, 120 and x.

So, x+ 120 + x = 180 (Linear pair)

2x+ 120 = 180

Now, Simplifying for x

Subtract 120 from both side we get

2x+ 120 - 120 = 180 - 120

2x = 60

Now, Divide both side by 2 we get

2x/ 2 = 60/ 2

x = 30

So, the measure of x is 30.

Answer:

150 sq. in.

Step-by-step explanation:
Because... Suppose the planned dimensions of a rectangular kitchen have a length-to-width ratio of 3 to 2. The length of the original kitchen is 6z feet. The original kitchen can be made larger by adding four feet to each original dimension. Write a polynomial expression that represents the floor area of the larger kitchen in square feet.

The polynomial expression that represents the floor area of the larger kitchen in square feet is  24z² + 40z + 16

The area of Rectangle is length times of width.

The length-to-width ratio of the original rectangular kitchen is 3 to 2.

Let the width of the original kitchen "w".

Then the length of the original kitchen is length = 3/2×w

We are also told that the length of the original kitchen is 6z feet. We can use this information to solve for the width of the original kitchen:

6z = 3/2×w

w = 4z

So the width of the original kitchen is 4z feet.

To make the kitchen larger, we add four feet to each original dimension. The new length is:

length = 6z + 4 feet

width = 4z + 4 feet

Area = (6z + 4 feet) × (4z + 4 feet)

Multiplying out the terms, we get:

Area = 24z² + 40z + 16 square feet

Therefore, the polynomial expression that represents the floor area of the larger kitchen in square feet is  24z² + 40z + 16

Answer:

B and C

Step-by-step explanation:

Kitten:

2 times in the morning and 2 times in the evening = 4 times per day

That means Ariane feeds her kitten 4k grams of food per day.

Dog:

1 time in the morning and 1 time in the evening = 2 times per day

That means Ariane feeds her dog 2d grams of food per day.

Answer:

If you find the total, you have to add the kitten's food per day and the dog's food per day. That is 4k + 2d, which is the same as choice B.

We can break 4k into 2k + 2k. We can also break 2d into d + d. We can write that as 2k + 2k + d + d. That equals the same as choice C, making it a correct choice.

Answer:

2:3

Step-by-step explanation:

x + y = 5      ----->      y = 5 - x

x - 2y = -1

x - 2(5 - x) = -1

x - 10 + 2x = -1

3x - 10 = -1

3x = 9

x = 3

(3) + y = 5

y = 2

Solution to this system: (3,2)

Ratio of y to x = 2:3

Finding x

Finding y

Answer:

miles to travel directly south = 54 miles (to the nearest mile)

extra miles = 68 miles (nearest mile)

Step-by-step explanation:

We need to find the height of the right triangle in the diagram.

To do this, use the sine trig ratio.

[tex]\sin(x)=\sf\dfrac{O}{H}[/tex]

where:

Given:

[tex]x[/tex] = 27°

O = height (h)

H = 120 miles

Substituting the given values into the formula:

[tex]\implies \sin(27^{\circ})=\sf\dfrac{h}{120}[/tex]

[tex]\implies \sf h=120 \sin(27^{\circ})[/tex]

[tex]\implies \sf h=54.47885997...[/tex]

Therefore, the shipmate will have to travel 54 miles (to the nearest mile) directly south.

To find the number of extra miles have been traveled, we first need to find the base length of the right triangle.

To do this, use the cos trig ratio.

[tex]\cos(x)=\sf\dfrac{A}{H}[/tex]

where:

Given:

Substituting the given values into the formula:

[tex]\implies \cos(27^{\circ})=\sf\dfrac{b}{120}[/tex]

[tex]\implies \sf b=120 \cos(27^{\circ})[/tex]

[tex]\sf \implies b=106.9207829...[/tex]

Therefore, the base of the right triangle is 106.9207829... miles

To find the extra miles, sum the hypotenuse and the height of the triangle, then subtract the base.

Extra miles = (120 + 54.47885997... ) - 106.9207829...

                  = 67.55807707...

                  = 68 miles (nearest mile)

No, because 2 squared is 4. 2 squared times 2 squared is really 4 x 4, which is 16. The side length is 4 because the formula for area of a sqaure is length x width (4 x 4 = 16) or one side squared (4 squared which is 16).

Step-by-step explanation:

Answer:

x < 2

Step-by-step explanation:

P = Number of favourable outcomes ÷ Sum of total outcomes

So, Probability of drawing a blue sock is

Number of blue socks ÷ Number of total socks

= 6 ÷ 20

= 3 ÷ 10

= 0.3

Now as we have drawn a sock already the total number of socks in the drawer are 19

So, the probability of drawing a blue sock now will be :

= 6 ÷ 19

= 0.31
