Answer:

The hose is ~70.71 ft long.

Step-by-step explanation:

We need to use Pythagorean theorem to figure this out. ( A^2 + B^2 = C^2)

So we first need to square 50 two times, since that's the length and height of the garden. This equals 5000.

Then we just need to find the root of 5000! This rounds out to about 70.71 ft.

Hope I could help! :)

The length of the hose which is ​stretched from one corner of the garden to another corner across the diagonal of it is 70.72 ft

The diagonal of the square is the distance from opposite vertices of it. There are two diagonals in a square which are equal in measure.

To find the diagonal of the square, the following formula is used.

d=a√2

Here, (a) is the length of the side of the square.

The side of a square garden is 50 ft long. One hose is stretch from one corner of the garden to another corner across the diagonal of it. Thus, the length of the diagonal is,

d=a√2

d=(50)√2

d=70.72 ft

Thus, the length of the hose which is ​stretched from one corner of the garden to another corner across the diagonal of it is 70.72 ft

f(x)=20+300x

Also, Rex should find a different pool because that fee is ridiculous.

The function rule in the given situation is a linear function and can be represented as C=20+300x. In this rule, 'C' is the total cost in dollars, '20' is the initial membership fee, '300' is the cost of each pool visit and 'x' is the number of pool visits.

The function rule in this situation is called a linear function. A function rule describes how to convert an input (in this case, the number of times Rex visits the pool) into an output (the total cost).

The function rule for this specific situation could be represented as C=20+300x, where 'C' is the total cost, '20' is the initial membership fee, '300' is the cost each time Rex goes to the couple, and 'x' is the number of times Rex goes to the pool.

So, each time Rex goes to the pool, you would multiply that number by 300 (the cost per visit), and then add 20 (the initial fee) to get the total cost.

Answer:

Step-by-step explanation:

ab - ac = d + e ← factor out a from both terms on the left side

a(b - c) = d + e ← divide both sides by (b - c)

a = [tex]\frac{d+e}{b-c}[/tex]

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

The slope m of the functions give the measure of the rate of change.

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

g(x) = [tex]\frac{5}{2}[/tex] x - 3 ← is in slope- intercept form

with slope m = [tex]\frac{5}{2}[/tex] = 2.5

Calculate the slope of f(x) using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, - 3.5) and (x₂, y₂ ) = (1, - 1) ← 2 points from the table

m = [tex]\frac{-1+3.5}{1-0}[/tex] = 2.5

Hence

The slopes of g(x) and f(x) are both m = 2.5, thus

The functions increase at the same rate → C

Answer:

65 ft by 39 ft

Step-by-step explanation:

Let x ft be the length of each part and y ft be the width of each part. The total perimeter of all 5 parts is

[tex]6x+10y=780[/tex]

The length of the large rectangle is 5y ft and the width of the large rectangle is x, so the total area is

[tex]A=x\cdot 5y[/tex]

From the first equation,

[tex]y=78-0.6x[/tex]

Substitute it into the area expression:

[tex]A(x)=x\cdot 5(78-0.6x)=390x-3x^2[/tex]

Find the derivative:

[tex]A'(x)=390-3\cdot 2x=390-6x[/tex]

Equate it to 0:

[tex]390-6x=0\\ \\6x=390\\ \\x=65[/tex]

Then

[tex]y=78-0.6\cdot 65=78-39=39[/tex]

Answer:

6 weeks.

Step-by-step explanation:

Let x be the number of weeks to be found.

Then  4.5x + 18 / 4x = 15/8

Cross multiply:

36x + 144 = 60x

24x = 144

x =  6  (answer).

In approximately 1.67 weeks (or rounded to 2 weeks), Theo and James will have savings in the ratio 15:8.

We can set up an equation to represent the savings of Theo and James over time. Let x be the number of weeks they have saved. Theo will have saved £4.50x and James will have saved £4x. We can set up the equation:

£4.50x / £4x = 15 / 8

Cross-multiplying the equation gives us:

8 * £4.50x = 15 * £4x

Simplifying the equation gives us:

36x = 60x

Dividing both sides by 36x gives us:

1 = 5 / 3x

Cross-multiplying again gives us:

3x = 5

Dividing both sides by 3 gives us:

x = 5 / 3

Therefore, in approximately 1.67 weeks (or rounded to 2 weeks), Theo and James will have savings in the ratio 15:8.

Step-by-step explanation:

Answer:b

Step-by-step explanation:

You're answer is b. All you have to do is a measurement

Answer:

B) 1/2 (154° - 46°)

Step-by-step explanation:

Here ∠XYZ is an angle subtended by two chords from a point outside of the circle.

It is a one of the circle.

If the angle subtended by two chords from the outside point of the circle, the measure of the angle is 1/2 times difference of the major arc and minor arc.

Here Major arc = 154° and minor arc = 46°

Applying the rule, we get

m∠XYZ = [tex]\frac{1}{2} (Major arc - Minor arc)[/tex]

m∠XYZ = 1/2 (154° - 46°)

Answer:

1. 30

2. 150

3. obtuse

4. acute

5. Adjacent

Step-by-step explanation:

The correct expression for the angles are;

1) m SUT equals  30 Degrees.

2) m TUW equals  150 degrees

3) TUW is obtuse angle

4) SUT is acute angle

5) TUW and SUT are Adjacent angles

Similar to corners, right angles have a 90° measure. Acute angles are less than ninety degrees. More than 90° but less than 180° are obtuse angles. Additionally, a straight angle is 180°, which is the point at which two lines merge into one by going in the same direction.

Any angle is composed of two rays that converge at a point known as the vertex. When two angles share a ray, it indicates that they are adjacent to one another.

Answer:

v = -3

Step-by-step explanation:

Step 1: Use the Distributive Property

6v + 3= -75v - 240

Step 2: Isolate v

81v = -243

Step 3: Simplify

v = -3

The value of v in the equation 3(2v + 1)=-15(5v + 16)​ is -3 after rearranging and solving.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have a linear equation in one variable:

3(2v + 1)=-15(5v + 16)​

6v + 3 = -75v -240

6v + 75v = -240 - 3

81v = -243

v = -3

Thus, the value of v in the equation 3(2v + 1)=-15(5v + 16)​ is -3 after rearranging and solving.
