Number of incorrect answers Rashida got = 12

Number of correct answers Rashida got = 18

Given :-

Points for each correct answer =

[tex] = 2 \frac{1}{4} [/tex]

Points for each incorrect answer =

[tex] = \frac{ - 1}{ \: \: \: 2} [/tex]

Points Rashida will get for her correct answers :-

[tex] = 2 \frac{1}{4} \times 18[/tex]

[tex] = \frac{(4 \times 2+ 1)}{4} \times 18[/tex]

[tex] = \frac{9}{4} \times 18[/tex]

[tex] = \frac{162}{4} [/tex]

[tex] = 40.5 \: points[/tex]

Points Rashida will get for her incorrect answer :-

[tex] = \frac{ - 1}{ \: \: \:2} \times 12[/tex]

[tex] = \frac{ - 12}{ \: \: \: \: \: 2} [/tex]

[tex] = - 6 \: points[/tex]

So , Rashida gets 40.5 points for her correct answer and -6 points for her incorrect answer .

Rashida's total score :-

[tex] = 40.5 + ( - 6)[/tex]

[tex] = 34.5 \: points[/tex]

Therefore , Rashida gets 34.5 points as her total score .

The overall score of Rashida will be 34.5 for the given exam.

Multiplication is the general procedure in mathematics in which we multiply two or more numbers to each other to find a new multiplied number.

Multiplication gives us a resultant number that will be very big as compared to the number which is going to be multiplied if and only if the number which is going to be multiplied is more than one.

Number of correct answers = 18

Points of correct answer = 2 1/4 = 9/4

Scores of correct answer = 18 × 9/4 = 40.5

Number of incorrect answers = 18

Scores of incorrect answer = 12 × (-1/2) = -6

Total score = 40.5 - 6 = 34.5

Hence "The overall score of Rashida will be 34.5 for the given exam".

The approximate value of q in the logarithmic equation is 0.585.

The given logarithmic equation is  [tex]\rm q+log_2(6)=2q+2[/tex]

It is required to find the value of  'q'.

What is Logarithm?

It is another way to represent the power of numbers and we say that 'b' is the logarithm of 'c' with base 'a' if and only if 'a' to the power 'b' equals 'c'.

[tex]\rm a^b=c\\\rm log_ac=b[/tex]

We have a logarithmic equation:

[tex]\rm q+log_2(6)=2q+2[/tex]

After simplification the above equation we get;

[tex]\rm q+log_2(6)=2q+2\\\rm q-2q=-log_2(6)+2\\\rm -q=-log_2(6)+2\\[/tex].....(1)

From the logarithmic table, we get the value of  [tex]\rm log_2(6)[/tex]

[tex]\rm log_2(6)=2.5849[/tex]  

Putting this value in equation (1), we get:

[tex]\rm -q=-log_2(6)+2\\\rm -q=-2.5849+2\\\rm -q=-0.5849\\\rm q=0.5849 \approx 0.585\\[/tex]

Thus, the approximate value of q in the logarithmic equation is 0.585.

The choices that contain equivalent statements are:

a) ln 3x = 6 → 3x = e⁶

c) log 4x = 8 → 4x = 10⁸

e) 5.6554 = 10ˣ → log 5.6554 = x

To determine which choices contain equivalent statements, let's analyze each option one by one:

a) ln 3x = 6 → 3x = e⁶

This statement is true. It represents the inverse relationship between the natural logarithm (ln) and the exponential function with base e. Taking the exponential of both sides of the equation allows us to isolate the variable.

b) log 3x = 9 → 9x = 10³

This statement is not true. It seems to confuse the base of the logarithm. If the logarithm is not specified with a base, it is usually assumed to be base 10 (log base 10). In this case, the correct equivalent statement would be 3x = 10⁹.

c) log 4x = 8 → 4x = 10⁸

This statement is true. Similar to the previous option, assuming a base 10 logarithm (log base 10), the equivalent statement would be 4x = 10⁸.

d) 0.577 = e⁵ˣ → ln 5 = x / 0.577

This statement is not true. The equation given at the beginning, 0.577 = e⁵ˣ, cannot be transformed into the second equation using the properties of logarithms or exponentials. The two statements are unrelated.

e) 5.6554 = 10ˣ → log 5.6554 = x

This statement is true. It correctly represents the relationship between the logarithm and exponential functions. By taking the logarithm (base 10) of both sides of the equation, we can solve for x.

In summary, the choices that contain equivalent statements are:

a) ln 3x = 6 → 3x = e⁶

c) log 4x = 8 → 4x = 10⁸

e) 5.6554 = 10ˣ → log 5.6554 = x

The dimension that maximize the are of the pen is 45 ft by 90 ft.

where

l = length

w= width

Therefore,

perimeter of a rectangle = 2(l + w)

The barn is occupying one part of the rectangle . Therefore,

perimeter = 2l + w

180 = 2l + w

w  = 180 - 2l

area = lw

Therefore,

area = l(180 - 2l)

area = 180l - 2l²

To maximize area

l = -b / 2a

l = - (180) / 2 × -2

l = -180 / -4

l = 45 ft

Therefore,

w = 180 - 2(45)

w = 180 - 90

Step-by-step explanation:

We need both measurements in the same units.

1 m = 100 cm

2 m = 2 × 1 m = 2 × 100 cm = 200 cm

15 cm to 2 m = 15 cm to 200 m

[tex](20,9)[/tex]

Step-by-step explanation:

Given

[tex]3x - 5y = 15[/tex]

Required

Form 4 pairs of (x,y) values

This question will be answered based on assumptions of x and y values;

Haven said that:

For point 1

Take x = 0

Substitute 0 for x in [tex]3x - 5y = 15[/tex]

[tex]3(0) -5y = 15[/tex]

[tex]-5y = 15[/tex]

Solve for y

[tex]y = 15/-5[/tex]

[tex]y = -3[/tex]

So; the first pair is:

[tex](0,-3)[/tex]

For point 2:

Take y = 0

Substitute 0 for y in [tex]3x - 5y = 15[/tex]

[tex]3x - 5(0) = 15[/tex]

[tex]3x = 15[/tex]

Solve for x

[tex]x = 15/3[/tex]

[tex]x = 5[/tex]

So, the pair is

[tex](5,0)[/tex]

For point 3:

Take x = 10

Substitute 10 for x in [tex]3x - 5y = 15[/tex]

[tex]3(10) - 5y = 15[/tex]

[tex]30 - 5y = 15[/tex]

Collect Like Terms

[tex]-5y = 15 - 30[/tex]

So, the pair is:

[tex](10,3)[/tex]

For point 4:

Take y = 9

Substitute 9 for y in [tex]3x - 5y = 15[/tex]

[tex]3x - 5(9) = 15[/tex]

Answer: 104 ft²

Step-by-step explanation:

To find the area of the figure, we can find the area of the rectangle and the triangle. After that, we add the two areas together.

Rectangle

A=bh

A=10×8           [multiply]

A=80

----------------------------------------------------------------------------------------------------------------

Triangle

A=bh/2

A=6×8/2         [multiply]

A=48/2           [divide]

A=24

Now that we have the areas, we can add them together.

A=80+24        [add]

A=104 ft²

Now, we know that the area is 104 ft².

Simple interest formula:

Total = start x ( 1 + rate x time )

Total = 14,000 x ( 1 + (0.015 x3))

Total = 14,000 x 1.045
