Which of these figures have lines of symmetry? If so, how many? ​

Answer:

3.

Step-by-step explanation:

From the question given above, the following data were obtained:

Logᵦ 8 = 3

Logᵦ 0.5 = – 1

Logᵦ 4B =?

Next, we shall determine the value of B. This can be obtained as follow:

Logᵦ 8 = 3

8 = B³

Take the cube root of both side.

B = 3√8

B = 2

Finally, we shall determine the value of Logᵦ 4B. This can be obtained as follow:

Logᵦ 4B =

B = 2

Logᵦ (4×2) = Logᵦ 8

Recall from the question given:

Logᵦ 8 = 3

Therefore,

Logᵦ 4B = Logᵦ 8 = 3

Thus, the value of Logᵦ 4B is 3.

Answer:

0.4942108acre,0.2 hectare

Step-by-step explanation:

Given

length of rectungular field =50m

its breadth = 40m.

Solution

Area=length×breadth

=50×40

=2000m^2

1)1 square metre =0.000247 acre

So2000m^2=0.4942108acre

2)2000m^2=0.2 hectare

Given :

A rectangular yard measuring 39 ft by 63 ft is bordered (and surrounded) by a 2 ft fence.

To Find :

The area of this walk.

Solution :

Area of whole park :

[tex]A=39\times 63\ ft^2\\\\A=2457\ ft^2[/tex]

Now, length and breadth after removing the fences is l = 63 - 2( 2) = 59 ft and b = 39 - 2( 2 ) = 35 ft.

Area of inner park :

A' = 35 × 59 ft²

A' = 2065 ft²

Therefore, area of fencing is 2457 - 2065 = 392 ft² .

Hence, this is the required solution.

Answer:

The length of Big Ben shadow is 252.8 feet

Step-by-step explanation:

The given parameters are;

The height of the Big Ben clocktower in London ≈ 316 feet tall

The length of the shadow Shana casts = 4-foot

The height of Shania = 5 feet

Therefore, we have, by similar triangles;

[tex]\dfrac{The \ length \ of \ the \ shadow \ Shana \ casts }{The \ height \ of \ Shania} = \dfrac{The \ length \ of \ the \ shadow \ The \ Big \ Ben \ casts}{The \ height \ of \ the \ Big \ Ben \ clocktower}[/tex]Substituting the values, gives;

[tex]\dfrac{4 \ feet}{5 \ feet} = \dfrac{The \ length \ of \ the \ shadow \ The \ Big \ Ben \ casts}{316 \ feet}[/tex]

[tex]The \, length \, of \, the \, shadow \, The \, Big \, Ben \ clocktower \ casts = 316 \ feet \times \dfrac{4 \ feet}{5 \ feet} = 252.8 \ feet[/tex]

The length of the shadow The Big Ben clocktower casts = The length of Big Ben shadow = 252.8 feet

252.8 feet

Answer:

  (x, y) = (-244/29, -80/29)

Step-by-step explanation:

A graph (2nd attachment) shows the solution to be non-integer values, so we'll use the "cross multiply method" to find the solution.

Rewriting the equations to general form gives ....

  2x -9y -8 = 0

  5x -8y +20 = 0

Writing the coefficients in two rows of four, we have the table as in the first attachment. (The first column is repeated as the 4th column.)

Now, the cross product differences are formed. Each "orange" cross product difference is the difference of the product of "blue" coefficients and the product of "yellow" coefficients. The same formula is copied to the right.

These difference numbers go, left to right, into the form ...

  1/p1 = x/p2 = y/p3 . . . . . . where p1, p2, p3 are the cross product differences

In this problem, the solution is ...

  x = -244/29 ≈ -8.414

  y = -80/29 ≈ -2.759

The temperature of City A is 5° C and temperature of City B is 4° C.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

4x = 8 + 3y.....................(1)

x − 2y = −3.......................(2)

Solving Equation (1) and (2), we get

4x = 8 + 3y

4( -3 + 2y) = 8 + 3y

-12 + 8y = 8 +3y

8y - 3y = 8 + 12

5y = 20

y= 4

and, x = -3 + 2y = -3 +2(4) = -3 + 8 = 5

Hence, the temperature of City A is 5° C and temperature of City B is 4° C.

System of Equations

c + r = 32 ..... Equation 1

2c + 4r = 72......... Equation 2

We have 28 chickens and 4 rabbits

Step-by-step explanation:

Let the number of chickens be represented by c

The number of rabbits be represented by r

From the question, John counts:a total of 32 heads

32 heads = a total of 32 animals

Hence:

c + r = 32....... Equation 1

c = 32 - r

Also, John counts:

A total of 72 legs in his backyard.

Chickens have: 2 legs

Rabbits have: 4 legs

Hence:

2c + 4r = 72......... Equation 2

System of Equations is:

c + r = 32 ..... Equation 1

2c + 4r = 72......... Equation 2

Lets us substitute 32 - r for c in Equation 2

2(32 - r) + 4r = 72

64 - 2r + 4r = 72

Collect like terms

- 2r + 4r = 72 - 64

2r = 8

r = 8/2

r = 4

This means we have 4 rabbits

Note:

c = 32 - r

r = 4

c = 32 - 4

c = 28

Hence, we have 28 chickens

Answer:

  Mark the lower tick marks with hour numbers; see what hour corresponds to 2/3 mile

Step-by-step explanation:

The upper number line is marked off in 1/3 mile increments.

The tick marks on the lower line divide the unit distance into 6 parts, instead of 3, so each mark on the lower line corresponds to 1/6 mile.

The problem statement tells you the completion rate is 1/6 mile per hour, so we can number the lower tick marks 0, 1, 2, 3, 4, 5, 6 hours, leaving the marks on the upper number line at 1/3 mile, 2/3 mile, and 1 mile.

Then the lower tick mark we have labeled 4 hours will correspond to the upper tick mark labeled 2/3 mile.

x = 1.2

Step-by-step explanation:

[tex]\frac{10x-3}{3}[/tex] + [tex]\frac{5x+2}{4}[/tex] = 5

You would want to make the denominators of both fractions the same first. Their lowest common multiple is 12, so we shall make the denominators 12 by multiplying the first fraction by 4 and the second fraction by 3.

[tex]\frac{4(10x-3)}{12}[/tex] + [tex]\frac{3(5x+2)}{12}[/tex] = 5

Simplify.

[tex]\frac{40x-12}{12}[/tex] + [tex]\frac{15x+6}{12}[/tex] = 5

Now we can combine both fractions together since their denominator is the same.

[tex]\frac{40x-12+15x+6}{12}[/tex] = 5

Simplify.

[tex]\frac{55x-6}{12}[/tex] = 5

Isolate 55x-6.

55x-6 = 5 × 12

Simplify.

55x-6 = 60

Isolate the 55x.

55x = 60+6

Simplify.

55x = 66

Answer:

240000

Step-by-step explanation:

Answer:

240,000

Step-by-step explanation:

Pretend it is only 4 ten thousands. It would be 40,000. Since it is 24, there are 2.4 times more digits, so it would be 240,000 since it is at least 10 times more than a thousand which would be the 40,000 .

In case anyone needs 24 ten thousandths in the future:

0.0024

0.00024 is equal to 24 hundred-thousandths and there are tenths (0.1), hundredths (0.01), and thousandths (0.001). Then ten thousandths would just be a step lower (0.0001) but since there are 24, it would go into the thousandths place but have the four in the ten thousandths. So it would be 0.0024.

The solution for the value of x by definition of linear pair angle is 21.

Used the concept of linear pair angle that states,

The sum of a linear pair angle in a straight line would be 180 degrees.

Given that the two linear pair angles are,

(3x + 18) and (4x + 15)

Now, the sum of linear pair angles would be 180 degrees.

Hence, it can be written as,

(3x + 18) + (4x + 15) = 180°

Solve for x,

3x + 4x + 18 + 15 = 180°

7x + 33 = 180

Subtract 33 on both sides,

7x = 180 - 33

7x = 147

Divide 7 on both sides,

x = 147/7

Therefore, the value of x is,

x = 21
