a) Ratio in fraction form to compare the number correct to the total questions for each test is [tex]\frac{17}{20}[/tex].

b) Yes, we compare these two ratios as they are written.

Jamaya got a better answer on the test on her second test, and you could compare these two ratios as they are written.

a)

First: Convert the each of scores into the percentages:

How do you convert the ratios to percentages? Well, first we have to convert ratio to a decimal or a fraction. Let's convert it to fraction. So, 19 out of 25 will become fraction [tex]\frac{19}{25}[/tex], and 17 out of 20 will become fraction [tex]\frac{17}{20}[/tex] . To convert fraction to percentage:

Divide numerator by denominator:

19 ÷ 25 = 0.76                                        AND                           17 ÷ 20 = 0.85

Multiply the quotient by 100

0.76 x 100 = 76                                      AND                        0.85 x 100 = 85

Add percent sign

76%                                                          AND                                                   85%

Now, two quantities are easier to compare. We can obviously see that 85% is the bigger [and better] than 76%. So, ratio that equals 85% - 17 out of 20 - is a better grade.

b)

Yes, you can compare the these two ratios, just find [positive] difference between the amount that she scored and the total number of scores that could be gained.

25 - 19 = 6

20 - 17 = 3

Since equation with 20 and 17 in it has a smaller difference, it is most likely to have a greater value [because that means that Jamaya got more right and less wrong, which means a greater mark which is also greater quantity].

The volume of the right rectangular prism= 1/3 cubic inches

In this question, we have been given a right rectangular prism is packed with cubes of side length 1/6 inch.

We need to find the volume of the rectangular prism if the prism is packed with 12 cubes along the length, 3 cubes along the width, and 2 cubes along the height.

The length of the rectangular prism would be,

l = 12 × 1/6

l = 2 inches

The width of the rectangular prism would be,

w = 3 × 1/6

w = 1/2 inches

The height of the rectangular prism would be,

h = 2 × 1/6

h = 1/3 inches

so, the volume of the rectangular prism would be,

V = l × w × h

V = 2 × 1/2 × 1/3

V = 1/3 cubic inches

Therefore, the volume of the rectangular prism = 1/3 cubic inches

We have to calculate the number of seconds for the flare to return to the sea.

We have an initial vertical speed of 448 ft/s.

The only force acting on the flare is gravity.

Then, we can model the heigth in function of time using the equation:

where h0 = 0 ft, vy = 448 ft/s and g = 32 ft/s².

Then, we can replace and calculate t for h(t) = 0, that is the time it took the flare to come back to the initial height (that is 0 ft):

Answer: it will take 28 seconds for the flare to return to the sea [Third option].

we have the sum of angles that are in a triangle to be = 180

such that we have to sum all of the triangles that we have here

10x + 9 + 3x + 13 + x + 4 = 180

we have to take the like terms

10x + 3x + x + 9 + 13 + 4 = 180

14x + 26 = 180

14x = 180 - 26

14x = 154

Find the GCD (or HCF) of numerator and denominator

GCD of 23 and 90 is 1

Divide both the numerator and denominator by the GCD

23 ÷ 1

90 ÷ 1

Reduced fraction:

23

90

Therefore, 23/90 simplified to lowest terms is 23/90.

Answer:

Step-by-step explanation:

it is not possible to simplify 23/90, the numerator and denominator can only be divided by 1 and it remains 23/90

We can simplify the mathematical expression to get:

[tex]\frac{(5 + \sqrt{3})*(5 - \sqrt{3} ) }{\sqrt{22} } = 4*\sqrt{2/11}[/tex]

Here we have the mathematical expression:

[tex]\frac{(5 + \sqrt{3})*(5 - \sqrt{3} ) }{\sqrt{22} }[/tex]

Remember the rule:

[tex](a + b)*(a - b) = a^2 + b^2[/tex]

Then the numerator can be rewritten as:

[tex]\frac{(5 + \sqrt{3})*(5 - \sqrt{3} ) }{\sqrt{22} } = \frac{5^2 - \sqrt{3}^2 }{\sqrt{22} } = \frac{25 - 9}{\sqrt{22} } = \frac{16}{\sqrt{22} }[/tex]

notice that 16*16 = 256 then we can rewrite:

[tex]\frac{16}{\sqrt{22} } = \sqrt{\frac{256}{22} } = \sqrt{\frac{128}{11} } = \sqrt{\frac{4*4*2}{11} }= 4*\sqrt{2/11}[/tex]

1:10000

means we are using the same metric on the map and in reality.

just 1 unit in the map corresponds to 10000 units in reality.

so, e.g. 1 cm on the map = 10000 cm in reality.

1 m = 100 cm

so, 10000 cm = 100 m.

therefore, 1 cm on the map = 100 m in reality.

but we need 5 km = 5000 m.

that is 50 times 100 m in reality or 1 cm on the map.

so, the length on the map is 50 cm.

An employee's pay is the amount of money that they are given each month by their employer, particularly if they work in an occupation like education, law, or medicine.

For instance, the lawyer received a big salary.

Given,

Ron Fortini received a 5.20% merit increase

2.75% cost-of-living increase

His new weekly salary is $968.80.

Solution:

Let's take his initial salary as x.

The total increase in Ron's salary = 5.20%+2.75% = 7.95%

i.e.,

107.95% * x = $968.80

107.95/100*x = 968.80

x = 968.80 * 100/107.95

x = 897.45

His weekly salary prior to the increases is $897.45.

If she will jump at a height of 13500 feet and she will pull the cord when she is 5000 feet above the ground, the equation for distance traveled during freefall is d(t)= [tex]16t^{2}[/tex], then she has to wait 23.05 seconds to pull the cord

The initial height = 13500 feet

The height at which she has to pull the cord = 5000 feet above the ground

The distance traveled to reach 5000 feet above the ground = 13500-5000

= 8500 feet

The equation for the distance traveled during the freefall d(t)= [tex]16t^{2}[/tex]

where d is the distance traveled

t is the time taken

Substitute the values in the equation

8500 = 16 × [tex]t^{2}[/tex]

[tex]t^{2}[/tex] = 8500/16

[tex]t^{2}[/tex] = 531.25

t = [tex]\sqrt{531.25}[/tex]

t = 23.05 seconds

Hence, If she will jump at a height of 13500 feet and she will pull the cord when she is 5000 feet above the ground, the equation for distance traveled during freefall is d(t)= [tex]16t^{2}[/tex], then she has to wait 23.05 seconds to pull the cord

The image of the setting sun most likely not described in great detail in "Because I Could Not Stop for Death" because it is a common symbol of death that requires little description.

Emily Dickinson's lyrical poem "Because I could not stop for Death" was originally printed in Poems: Series 1 in 1890, after her death. We don't know if Dickinson finished "Since I could not stop for Death" or if it was "abandoned" because her writing was never granted permission to be published.

In the poem "Because I could not stop for death the personified Death appears to Dickinson's poem's speaker. The poet's character speaks calmly about Death, the Afterlife, and the tranquility that comes with it. She represents Death as a young guy accompanying her in a carriage.

Using the definition of the secant, the angle is given as follows:

θ = 112.6º.

The secant of an angle θ is given by one divided by the cosine of the angle θ, that is:

sec(θ) = 1/cos(θ).

In the context of this problem, the numeric value of the secant of the angle is given as follows:

sec(θ) = -13/5.

This means that the following relation can be established:

1/cos(θ) = -13/5.

Hence we can solve to find the angle measure as follows, applying cross multiplication:

-13cos(θ) = 5

cos(θ) = -5/13.

Applying the inverse cosine, we have that:

θ = arccos(-5/13).

θ = 112.6º.

This angle has equivalent on other quadrants, as for example, in the third quadrant the cosine is also negative. However, in the third quadrant, the tangent is positive and we want a negative tangent, which is why the measure is of θ = 112.6º.
