Step-by-step explanation:

Complete question is;

How do the expressions 72 divided by 9 and -72 divided by (-9) compare when they are evaluated?

A. They have different values and are different signs.

B. They have different values but are the same sign.

C. They have the same value but are different signs.

D. They have the same value and the same sign

Answer:

D. They have the same value and the same sign

Step-by-step explanation:

For 72 divided by 9,it is;

72/9 = 8

Usually when we don't have any sign in front of a number, it is said to be positive.

Thus, the answer can be expressed as; +8

Also, when -72 is divided by (-9), it is;

-72/-9

The negative signs will cancel out to give; 8

Similar to the first division, since no sign is attached to 8,it is said to be positive as +8.

This means both divisions yield same values and same signs

Answer:

148⁰

Step-by-step explanation:

M< EDF = M< DFE (because the two angles are equal because the triangle has two equal sides)

2x + 8 = 3x + 4

8 – 4 = 3x - 2x

4=x or x=4

So M< EDF= 2x4+8 = 16⁰  

So M< EDF + M< DFE= 32⁰

180⁰- 32⁰ = 148⁰

Answer:

1) The speed after 5 seconds is 13.[tex]\bar 8[/tex] m/s

2) The distance traveled after 5 seconds is 34.7[tex]\bar 2[/tex] meters

Step-by-step explanation:

1) The given parameters are;

The mass of the hockey puck, m = 0.18 kg

The horizontal force applied by the player, m = 0.5 N

The time at which the speed is calculated, t = 5 seconds after the force is applied

Therefore;

From the equation for the applied force, F = m × a. where a represents the acceleration, by substituting the known values get;

0.5 = 0.18 × a

∴ a = 0.5/0.18 = 50/18 = 25/9 = 2.[tex]\bar 7[/tex]

a = 2.[tex]\bar 7[/tex] m/s²

The speed after 5 seconds is given from the kinematic equation, v = u + a·t

Where;

v = The final velocity

u = The initial velocity = 0 m/s

t = The time = 5 seconds

By substitution of the known values, we get;

v = 0 + 2.[tex]\bar 7[/tex] × 5 = 13.[tex]\bar 8[/tex]

The speed after 5 seconds = 13.[tex]\bar 8[/tex] m/s

2) The distance traveled, s, after 5 seconds is given by the equation, s = u·t + 1/2·a·t²

From which we have;

s = 0 × 5 + 1/2 × 2.[tex]\bar 7[/tex] × 5² = 34.7[tex]\bar 2[/tex]

The distance traveled after 5 seconds = 34.7[tex]\bar 2[/tex] meters

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that Monica makes tomato sauce with the plants she grows in her garden. she uses 3 basil leaves in her sauce for every 8 tomatoes. she is making a big batch of sauce with 32 tomatoes from her garden.

The number of basil leaves will be calculated as:-

3 basil leaves = 8 tomatoes

1 tomato = 3 / 8 basil leaves

32 tomatoes = ( 32 x 3) / 8 = 4 x 3 = 12

Therefore, the number of basil leaves required will be 12.

width of the rectangle = b = x

length of the rectangle = l = 8 + 2x

Perimeter of the rectangle = 70cm

Also, perimeter of the rectangle = 2(l + b)

70 = 2[x + (8 + 2x)]

70 = 2(x + 8 + 2x)

70 = 2(3x + 8)

70 = 6x + 16

70 - 16 = 6x

54 = 6x

The probability is  [tex]P(\= X > 12 ) = 0.72688[/tex]

Step-by-step explanation:

From the question we are told that

   The  mean is  [tex]\mu = 12.3 \ years[/tex]

    The standard deviation is  [tex]\sigma = 0.7 \ years[/tex]

    The sample size is  n = 14

Generally the standard error of the mean is mathematically represented as

         [tex]\sigma _{x} = \frac{\sigma}{\sqrt{n} }[/tex]

=>       [tex]\sigma _{x} = \frac{0.7}{\sqrt{14} }[/tex]

=>       [tex]\sigma _{x} = 0.1871[/tex]

Generally the probability that their mean life will be longer than 12 years is mathematically represented as

      [tex]P(\= X > 12 ) = P(\frac{\= X - \mu }{\sigma} > \frac{12 - 12.3}{ 0.1871 } )[/tex]

[tex]\frac{\= X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ \=  X )[/tex]

       [tex]P(\= X > 12 ) = P(Z > -0.6034 )[/tex]

From the z table  the area under the normal curve to the left corresponding to    -0.6034  is

Answer:

1. The curved surface area of the cone is 282.74 cm²

2. Radius of sphere r = 4.924 m

Step-by-step explanation:

1. Height of cone = 12 cm

Diameter of base of cone = 10 cm

Surface Area of cone = ?

The formula used is: [tex]A=\pi r(r+\sqrt{h^2+r^2})\\[/tex]

h= 12 cm

r = diameter/2 r = 10/2 = 5 cm

Putting values and finding surface area

[tex]A=\pi r(r+\sqrt{h^2+r^2})\\A=3.14*5 (5+\sqrt{(12)^2+(5)^2})\\A=15.7 (5+\sqrt{144+25})\\A=15.7 (5+\sqrt{169})\\A=15.7 (5+13)\\A=15.7(18)\\A=282.74 \ cm^2[/tex]

So, the curved surface area of the cone is 282.74 cm²

2. Sphere of Volume = 500 m³

We need to find radius of sphere

The formula used is: [tex]Volume=\frac{4}{3}\pi r^3[/tex]

Putting values and finding radius of sphere

[tex]Volume=\frac{4}{3}\pi r^3\\500=\frac{4}{3}*3.14* r^3\\500=4.186*r^3\\=> r^3=\frac{500}{4.186}\\r^3=119.446\\Taking \ cube \ root \ on \ both \ sides.\\\sqrt[3]{r^3}=\sqrt[3]{119.446}\\r= 4.924 \ m\\[/tex]

Answer:

A(w) = 692 - 12w - (8000/w)

Step-by-step explanation:

Since it has a total area of 500 cm², it means that;

A = hw

Where;

A is area

h is height

w is width

Thus;

500 = hw

h = 500/w

We are told that There is a margin around the edges of 4 cm at the top and 8 cm on the bottom and sides where nothing is printed.

Thus;

We have height as; (h - 4 - 8) and width as; (w - 8 - 8)

Thus;

Area = (h - 4 - 8) × (w - 8 - 8)

Area = (h - 12) × (w - 16)

We know that h = 500/w

And we want to find the printed area in terms of the width(w)

Thus;

A(w) = ((500/w) - 12) × (w - 16)

A(w) = 500 - 12w - 8000/w + 192

A(w) = 692 - 12w - (8000/w)

Using the area formula, the appropriate expression for the area of the poster is A(w) = - 8000/w - 12w + 692

Total Area = 500 cm²

Area = Length × width

Entire area can be expressed thus :

Area with print can be expressed thus :

Length with print = (l - 8 - 4) = (l - 12) cm

Height with print = (w - 2(8)) = (w - 16) cm

Area = (l - 12)(w - 16)

Area = (500/w - 12)(w - 16)

Expressing in terms of width :

A(w) = 500 - 8000/w - 12w + 192

A(w) = - 8000/w - 12w + 692

Hence, the required expression is : A(w) = - 8000/w - 12w + 692

[tex]r=160-12m[/tex]

Step-by-step explanation:

Heart rate will be represented by [tex]r[/tex], minutes will be represented by [tex]m[/tex].

Here's the equation I came up with:

[tex]r=160-12m[/tex]

We can also rearrange it to look like a point-slope equation. Either way works, it's the same equation.

[tex]r=-12m+160[/tex]

This works because her heart rate is decreasing by a constant value. The initial heart rate is like the y-intercept, while the amount that it decreases by is the slope.

I hope this helps!

The equation is y=160-12t where t is the time in minutes.

The solution of a linear equation is defined as the points, in which the lines represent the intersection of two linear equations. In other words, the solution set of the system of linear equations is the set of all possible values to the variables that satisfies the given linear equation.

Given here, After sprinting, Emilie has a heart rate of 160. As

she cools down, her heart rate falls by 12 beats therefore, we can form the equation as if the time  is t minutes of cooling down then we can the heartbeat at a given time as y=160-12t

Hence, the equation is y=160-12t where t is the time in minutes.

It has been a good while since I have done this type of work so I am deeply sorry if I am wrong.

The experimental probability of rolling an odd number is around  683.3333%, which is 58.3333% more than the theoretical probability.

Again I am deeply sorry if I am wrong, have a good rest of your day!

The experimental probability of rolling an odd number is 60%, which is 10% more than the theoretical probability.

The probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

A special 8-sided die is marked with the numbers 1 to 8.

It is rolled 20 times with these outcomes:

{3 4 5 2 7 1 3 7 2 6 2 1 7 3 6 1 8 3 5 6}

The experimental probability of rolling an odd number is :

⇒ 12/20

⇒ 0.6

The percentage of experimental probability = 0.6 × 100 = 60%

Theoretical probability as:

⇒ 4/8 × 100 = 50%

Difference between experimental and theoretical probability

⇒ 60 - 50 = 10%

Hence, the experimental probability of rolling an odd number is 60%, which is 10% more than the theoretical probability.

Answer:

Step-by-step explanation:

So First we know she pays (538.66) every month (12months in a year ) for (30) years

So 538.66*12*30 = 193,917.60

Then, we take his total payment minus the what he originally owed.

193,917.60 - 150,000 = $43,917.60

Susie's monthly mortgage payment on her $150,000 home is $538.66. If the loan has a 30-year term, the total interest she will have to pay throughout that time will be $43,917.60.

A mortgage is, to put it simply, a contract that a person forms after borrowing money from a lender (in this case, a bank) and giving the lender a guarantee (in the form of a real estate property) that the money will be paid back in full.

So first one must know  as she pays 538.66 every month as there are 12 months in a year and for 30 years, the payment calculation is:

538.66 × 12 × 30 = 193,917.60

Then, deduct the amount he originally owed from his total payment.

193,917.60 - 150,000 = $43,917.60

Therefore, the total interest she will have to pay throughout that time will be $43,917.60.
