Answer:

66 degrees

Step-by-step explanation:

if there are 66 one degree angles, all alll those together to get 66 degrees in total

The measure of the angle that is given with the given parameter is; 66°

We are told that ang angle is made up of 66 one-degree angles. Now, this means that each of the section of the main angle is one degree.

Thus, the value of 66 numbers of that angle will be;

66 * 1 = 66°

In conclusion, the measure of the angle is 66°.

Answer:

x=12(the side in parallel are equal.

Answer:

533.33 ft/min

Step-by-step explanation:

We are given that

x=3 feet

y=4 feet

Height of person,h=6 feet

[tex]\frac{dx}{dt}=400 ft/min[/tex]

Triangle ABC and A'B'C are similar because all right triangles are similar

By using similarity property

[tex]\frac{h'}{6}=\frac{7}{4}[/tex]

[tex]h'=10.5 feet[/tex]

[tex]x+y=3+4=7 feet[/tex]

[tex]\frac{h'}{6}=\frac{x+y}{y}[/tex]

[tex]\frac{10.5}{6}=\frac{x+y}{y}[/tex]

[tex]10.5y=6x+6y[/tex]

[tex]10.5y-6y=6x[/tex]

[tex]4.5y=6x[/tex]

Differentiate w.r.t t

[tex]4.5\frac{dy}{dt}=6\frac{dx}{dt}[/tex]

[tex]\frac{dy}{dt}=\frac{6\times 400}{4.5}ft/min[/tex]

[tex]\frac{dy}{dt}=533.33ft/min[/tex]

Hence, If the person is 6 feet tall and walks away from the lamp post at a speed of 400 feet per minute then his shadow moving at the rate 533.33 ft/min

The missing percentage of the given algebraic expression when calculated is; 15.18%

We want to find;

Percent * $3.32 = $0.32 + $0.184

First of all, let us add the terms on the right side of the equation to get;

Percent * $3.32 = $0.504

Next operation is to divide both sides by 3.32 using division property of equality to get;

Percent = 0.1518 = 15.18%

Step-by-step explanation:

Answer:

(a): x = 125 yards.

(c): x = 170 yards.

Step-by-step explanation:

Given

[tex]f(x) = x(200 - x)[/tex]

[tex]x = length\\\\[/tex]

[tex]f(x) = area[/tex]

Required

Determine the possible length

For a length to be possible or usable, the calculated area must be greater than 0.

(a): x = 125 yards.

[tex]f(x) = x(200 - x)[/tex]

Substitute 125 for x

[tex]f(125) = 125 * (200 - 125)[/tex]

[tex]f(125) = 125 * 75[/tex]

[tex]f(125) = 9375[/tex]

(b): x = 200 yards.

[tex]f(x) = x(200 - x)[/tex]

Substitute 200 for x

[tex]f(200) = 200 * (200 - 200)[/tex]

[tex]f(200) = 200 * 0[/tex]

[tex]f(200) = 0[/tex]

(c): x = 170 yards.

[tex]f(x) = x(200 - x)[/tex]

Substitute 170 for x

[tex]f(170) = 200 * (200 - 170)[/tex]

[tex]f(170) = 200 * 30[/tex]

[tex]f(170) = 6000[/tex]

(d): x = 225 yards.

[tex]f(x) = x(200 - x)[/tex]

Substitute 225 for x

[tex]f(225) = 200 * (200 - 225)[/tex]

[tex]f(225) = 200 * (- 25)[/tex]

[tex]f(225) = -5000[/tex]

(e): x = 210 yards.

[tex]f(x) = x(200 - x)[/tex]

Substitute 210 for x

[tex]f(220) = 200 * (200 - 210)[/tex]

[tex]f(220) = 200 * (- 10)[/tex]

[tex]f(220) = -2000[/tex]

From the above calculations, only values of x that are 125 and 170 makes the function true

Answer:

x = - 7.23

Step-by-step explanation:

3(x+6)= -3.68               Start with the breackets.

3x + 18 = - 3.69            Subtract 18 from both sides

3x = - 3.69 - 18

3x = -21.69                   Divide by 3

x = - 21.69/3

x = -7.23

Answer:

The loaf of brown bread contains a higher percentage of flour.

Step-by-step explanation:

To find the percentage of flour, we divide the amount of flour by the weight of the bread, and then multiply by 100. So

400g loaf of white bread:

228g of flour

[tex]P = \frac{228*100}{400} = 57\%[/tex]

57% of flour

800g loaf of brown bread:

472g of flour

[tex]P = \frac{472*100}{800} = 59\%[/tex]

59% of flour, so, a higher percentage

Answer:

[tex]\left(5n^2-4nm-9m^2\right)+\left(7n^2+4nm+8m^2\right)=12n^2-m^2[/tex]

Step-by-step explanation:

Given the expression

[tex]\left(5n^2\:-\:4nm\:-\:9m^2\right)\:+\:\left(7n^2\:+\:4nm\:+8m^2\right)[/tex]

Remove parentheses: (a) = a

[tex]=5n^2-4nm-9m^2+7n^2+4nm+8m^2[/tex]

Group like terms

[tex]=5n^2+7n^2-4nm+4nm-9m^2+8m^2[/tex]

Add similar elements: [tex]5n^2+7n^2=12n^2[/tex]

[tex]=12n^2-4nm+4nm-9m^2+8m^2[/tex]

Add similar elements: [tex]-4nm+4nm=0[/tex]

[tex]=12n^2-9m^2+8m^2[/tex]

Add similar elements:  [tex]-9m^2+8m^2=-m^2[/tex]

[tex]=12n^2-m^2[/tex]

Therefore, we conclude that:

[tex]\left(5n^2-4nm-9m^2\right)+\left(7n^2+4nm+8m^2\right)=12n^2-m^2[/tex]

Step-by-step explanation:

The required equation represents the number of bags of sand is b = 4920 ÷ 40.

The equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.

here,
To prepare for the winter season the manager of an outdoor ice skating rink ordered 4,920 pounds of sand to keep around the skating rink from being yo slippery One bag of sand is 40 points.
Let the number of bags be b,
40 × = 4920
b = 4920 ÷ 40

Thus, the required equation that represents the number of bags of sand is b = 4920 ÷ 40.
