minimum number of hoses needed = farthest length / length of a hose

convert the length of a hose to feet

1 yards = 3 feet

25 x 3 = 75 feet

230 / 75 = 3.1

4 hoses would be needed

Answer:

w = [tex]\frac{3}{2}[/tex]

Step-by-step explanation:

Given

[tex]\frac{x}{y}[/tex] = 6 and x = 36 , then

[tex]\frac{36}{y}[/tex] = 6 ( multiply both sides by y )

36 = 6y ( divide both sides by 6 (

6 = y

Then

[tex]\frac{y}{w}[/tex] = 4 , that is

[tex]\frac{6}{w}[/tex] = 4 ( multiply both sides by w )

6 = 4w ( divide both sides by 4 )

[tex]\frac{6}{4}[/tex]  = w , that is

w = [tex]\frac{3}{2}[/tex]

Three squares of sides 15 units, 9 units, and 12 units can form a

right-angled triangle.

A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.

Given, We have to form a right-angled triangle that has side lengths of

3 different squares.

Let, The first square has a side length of 9 units, and let this be the height of the right-angled triangle.

Another square has a side length of 15 units and this is the hypotenuse.

Therefore, the base of the triangle must be 15² - 9² = 225 - 81 = 144 = 12 units.

So, The third square must have a side length of 12 units.

Step-by-step explanation:

0.2x + 0.3 = 0.1x + 0.5 ( subtract 0.1x from both sides )

0.1x + 0.3 = 0.5 ( subtract 0.3 from both sides )

0.1x = 0.2 ( divide both sides by 0.1 )

x = 2

Answer:

See below for answers and explanations to the first 5 problems

Step-by-step explanation:

Problem 1:

cos(x) = 2/3

sec(x) = ?

sec(x) = 1/cos(x)

sec(x) = 1/(2/3)

sec(x) = 3/2

Problem 2:

sinβ = -5/6

cscβ = ?

cscβ = 1/sinβ

cscβ = 1/(-5/6)

cscβ = -6/5

Problem 3:

secφ = 2

tanφ = √3

sinφ = ?

secφ = 1/cosφ

tanφ = sinφ/cosφ

tanφ = sinφ/cosφ

tanφ = sinφ(1/secφ)

√3 = sinφ(1/2)

2√3 = sinφ

Problem 4:

secθ = 8

tanθ = 3√7

cscθ = ?

secθ = 1/cosθ

tanθ = sinθ/cosθ

cscθ = 1/sinθ

tanθ = sinθ/cosθ

tanθ = sinθ(1/cosθ)

3√7 = sinθsecθ

3√7 = sinθ(8)

(3√7)/8 = sinθ

cscθ = 1/sinθ

cscθ = 1/((3√7)/8)

cscθ = 8/(3√7)

cscθ = (8√7)/21

Problem 5:

sinθ = 2/√5

cosθ = 1/√5

tanθ = ?

tanθ = sinθ/cosθ

tanθ = (2/√5)/(1/√5)

tanθ = (2/√5)(√5)

tanθ = 2

Answer:

B. $5039.58

Step-by-step explanation:

compound interest formula: amount = p(1 + \frac{r}{n})^{nt}

p= principal ($2,300)

r= interest rate as a decimal (4% = 0.04)

n= number of times the principal is compounded per year (annually = onceper year so 1 time per year)

t= time in years (20 years)

new equation: amount = 2300(1+\frac{0.04}{1} )^{1*20}

That equation equals $2,739.58 which you add to the principal.

$2,739.58 + $2,300 = $5039.58

Option B is the correct answer.

A circle is a two-dimensional shape where the outer surface line is called the circumference and it has a radius.

We have,

A circle with a radius of 5 inches.

We need to fit the word from the following option that best fits the image given.

Circumference

It is the total length of the outer surface of the circle.

Radius

It is the length from the center of the circle to a point on the circle.

Diameter

It is twice the length of the radius.

The given word 5 inches is the radius of the circle.
