Answer:

Area = 25cm²

Step-by-step explanation:

Given

Length of a square = 4.89cm

Required

Estimate the area of the square

The question says that the length of the side of the square be approximated to 1 significant figure.

When 4.89cm is approximated, it gives 5cm.

At this point, the area of the square can be estimated.

Area = Length * Length

Area = 5cm * 5cm

Area = 25cm²

Hence, the estimated area of the square is 25cm²

Question 4. Option C,

Question 5. Option A

Step-by-step explanation:

Question 4.

Take a look at the procedure below;

[tex]34 / 5 = x / 6,\\34 * 6 = 5 * x,\\204 = 5 * x,\\\\x = 40.80\\\\Conclusion - Option C[/tex]

To solve this problem, you could have to cross - multiply, and through simple algebra, isolate x.

Question 5.

If Becky charges an amount per hour per baby, to determine the total amount she would earn, multiply the number of hours by the number of babies taken care of, and multiply that amount by the cost she demands per hour per baby;

[tex]Children = 3,\\Hours = 5,\\Amount Charged = 7,\\\\Profit = 3 * 5 * 7 = 105 Dollars,\\\\Conclusion - Option A[/tex]

Answer:

Use the quadratic formula

x = [-b  +- sqr root (b^2 - 4*a*c)] / 2a

x = [-3 +- sqr root (9 - 4*1*-7)] / 2

x = (-3 +- sqr root (37) / 2

x1 = 1.5414

Answer:

Step-by-step explanation:

Given

[tex]z(14x -2y)=7[/tex]

Required;

Solve for x, when

[tex]z(14x -2y)=7[/tex]

Divide both sides by z

[tex]\frac{z(14x -2y)}{z} = \frac{7}{z}[/tex]

[tex]14x -2y = \frac{7}{z}[/tex]

Add 2y to both sides

[tex]14x -2y + 2y= \frac{7}{z} + 2y[/tex]

[tex]14x = \frac{7}{z} + 2y[/tex]

Divide both sides by 14

[tex]\frac{14x}{14} = \frac{1}{14}(\frac{7}{z} + 2y)[/tex]

[tex]x = \frac{1}{14}(\frac{7}{z} + 2y)[/tex]

The above expression is the value of x when [tex]z\neq 0[/tex]

To solve for when z = 0, we simply substitute 0 for z

[tex]x = \frac{1}{14}(\frac{7}{z} + 2y)[/tex]

[tex]x = \frac{1}{14}(\frac{7}{0} + 2y)[/tex]

0 cant't divide any number; hence, from the above expression we conclude that

[tex]x = \ u\ n\ d\ e \ f\ i \ n\ e\ d[/tex]

x doesn't have a solution

Answer:

[tex]x=1/2[/tex]

Step-by-step explanation:

[tex]27 = 3^{4x+1}[/tex]

[tex]3^3 = 3^{4x+1}[/tex]

[tex]3=4x+1[/tex]

[tex]2=4x[/tex]

[tex]2/4=x[/tex]

The value of x in the given equation is 1/2

An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Given is an equation, [tex]27 = 3^{4x+1}[/tex]

Solving for x,

3³ = [tex]3^{4x+1}[/tex]

Answer:

x=100

Step-by-step explanation:

Because they are vertical angles, AEG=FEB

You can see that FED+DEB=FEB

Therefore, 80+20=FEB=100

Since FEB=100 and FEB=AEG

AEG=100

Answer:

100°

Step-by-step explanation:

In this question, vertical angles are key. If you didn't know, vertical angles are basically opposites of each other. A pair of vertical angles are equal.

ACE = 20°

FED = 80°

FED and CEG are vertical angles (+the 20 from ACE), so your answer is 100°

Answer:

x < 5.1

Step-by-step explanation:

Let's define:

Using Law of Sines we can find x, as follows:

10/sin(95°) = 8/sin(α)

sin(α) = sin(95°)*8/10

α = arcsin(0.8) = 53.13°

β = 180° - 95° - 53.13° = 31.87°

x/sin(β) = 10/sin(95°)

x = 10/sin(95°)*sin(31.87°)

x = 5.3

On the other hand, we know that the addition of the two shorter sides of a triangle must be greater than the long side of the triangle. Therefore:

8 + 5.3 > 3x - 2

Solving:

8 + 5.3 + 2 > 3x  

15.3/3 > x

5.1 > x

or

x < 5.1

The value of x from the given inequality is x < 5.1

Inequality expressions are expressions that are not equal to each other

Given the following variables;

Using the sine law to determine the value of x

10/sin(95°) = 8/sin(α)

sin(α) = sin(95°)*8/10

α = arcsin(0.8) = 53.13°

β = 180° - 95° - 53.13° = 31.87°

x/sin(β) = 10/sin(95°)

x = 10/sin(95°)*sin(31.87°)

x = 5.3

Also, using the rule that states that the addition of the two shorter sides of a triangle must be greater than the long side of the triangle. Hence;

8 + 5.3 > 3x - 2

8 + 5.3 + 2 > 3x  

15.3/3 > x

5.1 > x

x < 5.1

Hence the value of x from the given inequality is x < 5.1

Answer:

16

Step-by-step explanation:

Triangle area = (1/2)*b*h

Base = b = 4

Height = h = 8

Area = (1/2) * 4 * 8 =  16

The area of the polygon shown in the figure is 16 unit square.

A polygon is a closed figure made up of three or more line segments connected end to end.

Triangle is a polygon that has three sides and three vertices. It is one of the basic figures in geometry.

The area of the triangle is defined as the product of half the base and the height of the triangle.

The area of the triangle = 1/2 x b x h

WE can see from the given figure;

The Base = b = 4

The Height = h = 8

The Area of figure = (1/2) * 4 * 8

The Area of figure =  16

Hence, the area of the polygon shown in the figure is 16 unit square.

Answer: 1018 sq. mm.

Step-by-step explanation:

Area = πr^2

= π x 18^2

= 324π

The required area of a circle is 1018 millimeters² with a diameter of 36 millimeters.

The area of the circle is equal to the product of the square of the radius of the circle and pi.

A = πr²

where 'r' is the radius of the circle

As per the question, we have

The diameter of the circle = 36 millimeters

The radius of the circle = diameter/2

The radius of the circle = 36/2 = 18 millimeters

The area of the circle = πr²

The area of the circle = π × 18²

The area of the circle = 3.14 × 324

The area of the circle = 1018

Thus, the required area of a circle is 1018 millimeters² with a diameter of 36 millimeters.

Step-by-step explanation:

Simply replace the (x, y ) pair of values in the equation and see if the equality holds:

Pair (0, -8) :

9 (0) + 2 (-8) = -16  therefore this pair is NOT a solution of the equation

Pair (3, -7):

9 (3) + 2 (-7) = 27-14 = 13  therefore this pair IS a solution of the equation

Pair (1, 2):

9 (1) + 2 (2) = 9 + 4 = 13  therefore this pair IS a solution of the equation
