Determine the angle measure of the following angles ?

1) b =
2) m=
3) h=
4) g=
5) i=
6) j=

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.

Answer:

r

0.15r

1.15r

Step-by-step explanation:

The problem states that r cm of rain fell on the garden on Thursday, so the first answer is:

The centimeters of rain on Thursday    r

On Saturday, 15% more rain fell than on Thursday. The extra amount of rain on Saturday, as compared to Thursday is 15% of r. 15% of r is the same as 15% times r. 15% can be written as a decimal as 0.15, so 15% of r is the same as 0.15r. This is the answer to the second line.

How many more centimeters of rain fell on Saturday than on Thursday   0.15r

The amount of rain on Saturday is the amount of rain on Thursday plus the additional 15%. We already know that the additional 15% of rain is 0.15r. The total amount of rain on Saturday is r + 0.15r = 1r + 0.15r = 1.15r. That answers the third question.

The centimeters of rain on Saturday     1.15r

the missing exponent would be 2

[tex]\bf (5^?)^{3}=5^1\implies 5^{?\cdot 3}=5^1\implies \stackrel{\textit{same base, the exponents must also be the same}}{?3=1\implies ?=\cfrac{1}{3}}[/tex]

Answer: 52.5 units squared

Step-by-step explanation:

The formula to find the area of a trapezoid is, (base1 + base2)/2 * height

So you find out which variable is which

Base 1 = 4

Base 2 = 3

Height = 15

Then plug it into the formula,

(4+3)/2 * 15

Then solve the order of operations

7/2 * 15

3.5 * 15

52.5 is the answer

Answer:

52.5

Step-by-step explanation:

Formula

Area = (1/2) (a + b)*h

Givens

a = 4

b = 3

h = 15

Solution

Area = (4 + 3)*15/2

Area = 7 * 15/2

Area = 105/2

Area = 52.5

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:D

Step-by-step explanation:

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.

You have to begin by using the triangle sum therom. That means Angle DEC would be 64°, Angle D would be 76°, and angle C would be 40°

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]

The transformed image will be located in Quadrant III.

To solve this problem, we can think about what happens to the hour hand when it is rotated 90 degrees counterclockwise around the origin, and then reflected across the x-axis.

Rotation: When the hour hand is rotated 90 degrees counterclockwise around the origin, it moves to the position of the 3 o'clock hour. This means that the x and y coordinates of the tip of the hour hand are swapped. For example, if the tip of the hour hand was originally at (3, 4), after the rotation it would be at (4, 3).

Reflection: When the hour hand is reflected across the x-axis, its y-coordinate is multiplied by -1. This means that if the tip of the hour hand was at (4, 3) after the rotation, after the reflection it would be at (4, -3).

Now, let's look at the quadrants:

Quadrant I: x > 0, y > 0

Quadrant II: x < 0, y > 0

Quadrant III: x < 0, y < 0

Quadrant IV: x > 0, y < 0

Before the rotation, the tip of the hour hand is in Quadrant I, because both its x and y coordinates are positive.

After the rotation and reflection, the tip of the hour hand is in Quadrant IV, because its x-coordinate is still positive and its y-coordinate is now negative.

Therefore, the image will be in Quadrant III.

Answer:

 150 minutes, or 2 1/2 hours

Step-by-step explanation:

You want to know the time required to empty a pond with the given dimensions if the level drops 20 cm in the first 30 minutes of pumping.

The average depth of the pond is the average of the depth at the shallow end and the depth at the deep end:

  (0.6 m + 1.4 m)/2

  = 2.0 m/2 = 1.0 m = 100 cm

If the level drops at the rate of 20 cm in 30 minutes, the time required for dropping the level by 100 cm is ...

  t/(30 min) = (100 cm)/(20 cm)

  t = 5·30 min = 150 min

The time to empty the pond completely is 150 minutes, or 2 1/2 hours.

Additional comment

As you know from the formula for the area of a trapezoid —

  A = 1/2(b1 +b2)h

the area is equivalent to that of a rectangle with base equal to the average of the two base lengths.

Here, the volume of the pond is the product of the area of the trapezoidal face and the pond width (1 m). That trapezoidal face has an area equivalent to that of a rectangle 1 m high and 2 m wide. The 1 m height is the depth we used in the above calculation.
