Answer:

Step-by-step explanation:

to compare them, we need to convert them into like fractions

4/3 and 5/2

lcm of 3 and 2 is 6

4/3 × 2/2 = 8/6

5/2 × 3/3 = 15/6

15/6 is greater than 8/6

so 5/2 is greater than 4/3

similarly,

-3/2 and -4/5

we need to convert them into like fractions

lcm of 2 and 5 is 10

-3/2 × 5/5 = -15/10

-4/5 × 2/2 = -8/10

-8/10 is greater than -15/10

so -4/5 is greater than -3/2

Answer:

15 multiple choice questions

5 free response questions

Step-by-step explanation:

This is basically a systems of equations word problem.

To solve this, we need to create two equations that represent this scenario. Let's suppose [tex]m[/tex] represents the amount of multiple choice questions and [tex]f[/tex] represents the amount of free-choice questions.

We can create the following equations:

[tex]4m + 8f = 100[/tex]

[tex]m+f=20[/tex]

To solve for m and f, we can use elimination.

Let's multiply the equation [tex]m+f=20[/tex] by -4.

[tex]-4m - 4f = -80[/tex]

Great! Now let's add this equation to our first one, [tex]4m + 8f = 100[/tex].

[tex]4m + 8f = 100[/tex]

[tex]-4m - 4f = -80[/tex]

___________________

[tex]0m + 4f = 20[/tex]

[tex]4f=20[/tex]

Dividing both sides by 4 get us [tex]f=5[/tex].

So there are 5 free choice questions. To find m, we can substitute inside the equation [tex]m+f=20[/tex]

[tex]m+5=20\\\\m=20-5\\\\m=15[/tex]

So there are 15 multiple choice questions.

Answer:

Second option, scale factor is 2.5

Step-by-step explanation:

We see that ∠B ≅ ∠E and ∠C ≅ ∠F, therefore, ΔABC ~ ΔDEF by the AA Similarity for Triangles Theorem which states that if two pairs of corresponding angles are congruent in two triangles, then those two triangles are similar. To find the scale factor, all we have to do is DF / AC = 5/2 or 2.5.

Answer:

129 degrees

Step-by-step explanation:

Space from D and E = 75

Space from E and F = 54

Space from D and F = 75 + 54

=> Space from D and F = 129 degrees

When two straight lines or rays intersect at a shared endpoint, an angle is generated. The measure of ∠DCF is 132°.

When two straight lines or rays intersect at a shared endpoint, an angle is generated. An angle's vertex is the common point of contact. Angle is derived from the Latin word angulus, which means "corner."

The diagram for the given explanation can be made as shown below.

Given the measure of ∠DCE and ∠ECF as 78° and 54°, respectively. Therefore, we can write,

∠DCF = ∠DCE + ∠ECF

= 78° + 54°

= 132°

Hence, the measure of ∠DCF is 132°.

Answer:

Kenji walks 3 miles in an hour.

Step-by-step explanation:

1 hour = 3600 seconds

3600/10 = 360

So there are 360 increments of 10 in an hour. Multiply 44 by 360 to find the amount of feet in an hour:

(44)(360) = 15840

Now we have to divide 15,840 by the amount of feet in a mile (5,280):

15840/5280 = 3

So Kenji walks 3 miles in an hour.

Kenji walks 3 miles in one hour.

We know that,

        1 hours = 60 minutes = 3600 seconds

Since, Kenji walks 44 feet in 10 seconds

Kenji walks in 1 second,[tex]=\frac{44}{10}=\frac{22}{5}feet[/tex]

Kenji walks in 3600 seconds , [tex]=\frac{22}{5}*3600=15840feet[/tex]

Given that,  1 mile = 5,280 feet

So that,    [tex]15840feet=\frac{15840}{5280}=3miles[/tex]

Thus, Kenji walks 3 miles in one hour.

Complete Question

The  complete question is shown on the first uploaded image

Answer:

The solution is  [tex]y^2 = \frac{1}{ 3 - 2 (1 + x^2 ) ^{\frac{1}{2} }}[/tex]    

Step-by-step explanation:

From the question we are told that

  The  function is  [tex]\left \{ {{y' =  xy^3 (1 + x^2)^{-\frac{1}{2} }} \atop {y(0) =  1}} \right.[/tex]

Generally the above  equation can be represented as

      [tex]\frac{dy}{dx}  =  xy^3  (1+ x^2)^{- \frac{1}{2} }[/tex]

      [tex]=>   \frac{dy}{y^3}  =  \frac{x}{ (1 + x^2)^{\frac{1}{2} }} dx[/tex]

     [tex]\int\limits { \frac{dy }{y^3} } \,    =  \int\limits {\frac{x}{(1 + x^2) ^{\frac{1}{2} }} } \, dx[/tex]

=>    [tex]- \frac{1}{2y^2}  =  (1 + x^2)^{\frac{1}{2} }+ C[/tex]

From the question we are told that at y(0) =  1

     [tex]- \frac{ 1}{2 * (1) } =  (1 + (0)^2)^{\frac{1}{2} } + C[/tex]

     [tex]C =  - \frac{3}{2}[/tex]

So

       [tex]- \frac{1}{2y^2}  =  (1 + x^2)^{- \frac{1}{2}}  - \frac{3}{2}[/tex]      

     [tex]\frac{1}{y^2}  =  3-2(1 + x^2)^{\frac{1}{2} }[/tex]

     [tex]y^2 = \frac{1}{ 3 - 2 (1 + x^2 ) ^{\frac{1}{2} }}[/tex]    

Complete question :

Suppose there are n independent trials of an experiment with k > 3 mutually exclusive​ outcomes, where Pi represents the probability of observing the ith outcome. What would be the formula of an expected count in this​ situation?

Answer: Ei = nPi

Step-by-step explanation:

Since Pi represents the probability of observing the ith outcome

The number of independent trials n = k>3 :

Expected outcome of each count will be the product of probability of the ith outcome and the number of the corresponding trial.

Hence, Expected count (Ei) = probability of ith count * n

Ei = nPi

The formula of an expected count is given by .

[tex]E_i=np_i[/tex]

Suppose there are n independent trials of an experiment with k > 3 mutually exclusive outcomes,

where pi represents the probability of observing the ith outcome.

The expected counts for each possible outcome are given by .

[tex]E_i=np_i[/tex]

Where, [tex]p_i[/tex] is the probability of observing the ith outcome

[tex]E_i[/tex] is the expected count of the ith outcome.

When you want to round up or down numbers focus on only two digits,which is the digit in place that you are rounding to and the digit to it's immediate right which tells you whether to round up or down.When the number you are rounding is between 0-4, you round down to the next lowest number. When the number is 5-9,you round the number up to the next highest number.

For example: If you have 25 and you want to round it up then it will be rounded up to 3 because 5 can be rounded up to the next number which is 2 to make it 3.But when you have 23,then you can't round it up which means you will have to round it down to 20 since the 3 behind the 2 can't round up.

The linear speed of the wheel is v=175.84 inches inches per second.

The radius of the wheel (r) is 7 inches.

We know the circumference of a circle is given by: [tex]\pi\times2r[/tex]

Therefore the circumference of the wheel is [tex]\pi\times2\times 7[/tex] inches

= [tex]14\pi[/tex] inches

The wheel revolves at 4 revolutions per second.

Hence the wheel will go forward [tex]4\times14\pi[/tex] inches in one second

That is, [tex]56\pi[/tex] inches in one second.

Use the value [tex]\pi = 3.14[/tex]

[tex]56\times 3.14[/tex] inches

175.84 inches

Hence, the linear speed of the wheel is v=175.84 inches inches per second.

Answer:

y = 10(1.03)^x

Step-by-step explanation:

In the formula y = p(1 + r)^x, p is the starting amount and r is the growth rate.

In this problem, the starting amount is 10. So, p = 10.

The growth rate is 3% each week, which is the same as 0.03 as a percentage. So, r = 0.03.

Plug these into the equation:

y = 10(1.03)^x will be the equation for this situation

The equation that best represents the depth of the pond each week is y = 10(1.03)× option (D) is correct.

It is defined as the function that rapidly increases and the value of the exponential function is always positive. It denotes with exponent y = a×

where a is a constant and a>1

We have:

A pond increases 3% each week.

The exponential growth is represented by:

y = p(1 + r)×

p = 10 feet

r = 3% = 0.03

y = 10(1 + 0.03)×

y = 10(1.03)×

Thus, the equation that best represents the depth of the pond each week is y = 10(1.03)× option (D) is correct.

Answer:

66 jars of jam

Step-by-step explanation:

Elizabeth is selling jam at a farmers market.

She earns $5 for each jar of Jan that she sells

Her goal is to earn $450 during the weekend.

Elizabeth has already made $95 from the sale of her jams and $24 from leading a demonstration

Therefore the total amount that has been made is

= $95 + $24

= $119

Since her target is $450 and she has already made $119 then the amount remaining to complete the target can be calculated as follows

= $450 - $119

= $331

The minimum number of jars that Elizabeth must sell to realize her goal can be calculated as follows

= 331/5

= 66

Hence Elizabeth must sell 66 jars of jam to reach her goal.
