-254 = -10k - 2 - 8k

Answers

-254 = -10k -2 -8k

or, -254+2 = -18k

or, -252 = -18k

or, k = -252/-18 = 14

Answer is 14.

Answer: k = 14

Step-by-step explanation:

First combine like terms: -254 = -18k - 2

Next use Addition Property of Equality (add 2 to both sides to cancel the 2 on the right side of the equation) : -252 = -18k

Last, use Division Property of Equality (divide both sides by -18 to get k by itself): 14 = k

*when solving an equation like this, you are always trying to get k by itself, and whatever you do to one side, do it to the other to keep them equal

Part A which equation can be used to find x,the total number of jerseys purchased?
A)3.99(x+15.70)=82.49
B)15.70x - 3.99 = 82.49
C)82.49-3.99 + 15.70=82.49
D)15.70x + 3.99 = 82.49

Part B using mathematical reasoning explain why the other three equations are incorrect.


Pazzi how many total jerseys in Ms Chen purchase. SHOW YOUR WORK


Answer:______ Shirts

Answers

The equation that can be used to find x, the number of jerseys is 82.49 = 15.70x + 3.99

The other three equations are incorrect because the equation should be represented by total cost equals cost of each shirt multiplied by number of jerseys plus shipping cost.

Ms Chen purchased 15 jerseys.

How to write equations?

Cost of x jerseys including shipping = $82.49

Cost of shipping = $3.99

Cost of each jersey = $15.70

82.49 = 15.70x + 3.99

82.49 - 3.99 = 15.70x

78.50 = 15.70x

x = 78.50 / 5

x = 5

Step-by-step explanation:

The figure is a right triangle with hypotenuse = QS

The  base from the graph = 4 units
(or you can just subtract the x-coordinates 2 - (-2) = 4)

The height from the graph is 3 units
(Or you can subtract the y-coordinates: 1 - (-2) = 3)

Since this is a right triangle the square of the hypotenuse = sum of squares of the other two sides

QS² = 3² + 4² = 9 + 16 = 25

QS, the hypotenuse = √25 = 5

The perimeter = sum of the sides = 3 + 4 + 5 = 12 units

after a year, assuming she makes no additional withdrawals or deposits?

Answers

Adrian must multiply his money by 1.03 to find his total balance in a year in one step.

What is simple interest?Borrowers must pay simple interest to lenders as a fee for a loan. Compound interest is not taken into account while calculating it; just the principal is used. Simple interest is applicable to all loans. It is also the form of interest that banks give their customers on their savings accounts. There are two techniques to compute interest: simple interest and compound interest. The principal, or initial amount of a loan, is used to compute simple interest. Compound interest, sometimes known as "interest on interest," is calculated using both the original amount and the total accumulated interest from prior periods.

The following calculation must be done in order to determine what Adrian should multiply his current balance by in order to find his total balance in a year in one step, assuming that no money will be added to or subtracted from the investment. Adrian invests money in an account that offers simple interest of 3% per year.

Current balance = X

Interest = 3% = 3/100 = 0.03

Interest + principal = 1.03

1.03X = Total balance in a year

Therefore, Adrian must multiply his money by 1.03 to find his total balance in a year in one step.

The mean June midday temperature in Desertville is 36°C and the standard deviation is 3°C.Assuming this data is normally distributed, how many days in June would you expect the midday temperature to be between 39°C and 42°C?

Answers

Answer:

The value is  \(E(X) = 4 \ days\)

Step-by-step explanation:

From the question we are told that

   The mean is  \(\mu = 36^oC\)

    The standard deviation \(\sigma = 3^oC\)

Generally the probability that in June , the midday  temperature is between  

39°C and 42°C is mathematically represented as

      \(P(39 < X < 42) = P(\frac{39 - 36}{3} < \frac{X - \mu }{\sigma} < (\frac{42 - 36}{3} )\)

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

      \(P(39 < X < 42) = P(1 < Z <2 )\)

=>   \(P(39 < X < 42) = P(Z < 2) - P( Z <1 )\)

From the z table  the area under the normal curve to the left corresponding to  1 and  2  is

     P(Z   < 2)  = 0.97725

and

    P(Z   < 1)  = 0.84134

    \(P(39 < X < 42) = 0.97725 - 0.84134\)

=>  \(P(39 < X < 42) = 0.13591\)

Generally number of days in June would you expect the midday temperature to be between 39°C and 42°C

      \(E(X) = n * P(39 < X 42 )\)

Here n is the number of days in June which is  n = 30

       \(E(X) = 30 * 0.13591\)

=>    \(E(X) = 4 \ days\)

A=

Answers

The total surface area of the clubhouse including the floor is approximately 95.98 square feet.

We have,

The surface area of a square pyramid can be found by adding the area of the base to the sum of the areas of the four triangular faces.

Since the base is a square, its area is 6^2 = 36 square feet.

Each triangular face is an equilateral triangle with a side length of 6 feet, so its area can be found using the formula.

A = (√(3)/4) x s²,

where s is the length of a side.

The area of each triangular face.

A = (√(3)/4) x 6² = 9 √(3) square feet.

The total surface area is then:

A = 4 x 9 √(3) + 36

A = 36 √(3) + 36  ≈ 95.98 square feet

(rounded to the nearest hundredth)

Therefore,

The total surface area of the clubhouse including the floor is approximately 95.98 square feet.

In a library, the ratio of maths books to science books is 3 : 2 and the ratio of science books to history books is 1 : 3. If the total number of books is 220, how many maths books are there?

Answers

Answer:

60 maths books

Step-by-step explanation:

Let the following be:

Maths books = mScience books = sHistory books = h

And we have ratios and sum:

m/s = 3/2s/h = 1/3m+s+h = 220

From the ratios we get:

m = 3s/2h= 3s

Considering the above in the sum of books:

m+s+h = 2203s/2 + s + 3s = 2203s + 2s + 6s = 2*22011s = 440s = 440/11s = 40

Find the value of c such that the three points (5,5), (-3,1), and (6,c) lie on the same line. Note: Three points are on the same line if the slope of the line through any two points is always the same.

Answers

Answer:

c = 5.5

Step-by-step explanation:

We can find the slope of the line using the given points (5,5) and (-3,1) using rise over run:

-4/-8 = 1/2

Now, we can plug in the slope and a point into the equation y = mx + b to find b:

5 = 1/2(5) + b

5 = 2.5 + b

2.5 = b

Then, we can plug in 6 in the point (6,c) to find c:

y = (1/2)(6) + 2.5

y = 3 + 2.5

y = 5.5

c = 5.5

Answer:

c = 5.5

Step-by-step explanation:

Find the slope with two points

m = (y2-y1)/(x2-x1)

m = (1-5)/(-3-5)

   = -4/-8

   = 1/2

If all the points are on the same line, then they have the same slope

m = (y2-y1)/(x2-x1)

Using the first and third points

1/2 = (c-5)/(6-5)

1/2 =  (c-5)/1

1/2 = c-5

Add 5 to each side

5+1/2 = c

At one college, GPAs are normally distributed with a mean of 2.9 and a standard deviation of 0.6. Find the 70th percentile.

Answers

The GPA corresponding to the 70th percentile at the college is approximately 3.246 based on standard deviation.

We can use the conventional normal distribution table or a calculator with a normal distribution function to determine the 70th percentile of GPAs at a college, which are normally distributed with a mean of 2.9 and a standard deviation of 0.6.

The inverse normal distribution function with a mean of 2.9, a standard deviation of 0.6, and a percentile of 70 can be used on a calculator. This results in:

\(3.246 for invNorm(0.7, 2.9, 0.6).\)

As a result, the GPA that represents the 70th percentile is roughly 3.246.

We can determine the z-score corresponding to the 70th percentile, which is 0.5244, by using a common normal distribution table. Thus, we may apply the equation z = (x - ) /, where x is the GPA that corresponds to the 70%ile, is the mean, and is the standard deviation, and all three variables have values of 2.9. After finding x, we obtain:

0.5244 = (x - 2.9) / 0.6

x = 3.246

Once more, doing so yields the same outcome as using a calculator.

In conclusion, the GPA at the college that represents the 70th percentile is roughly 3.246.

17. A hemisphere of lead of radius 7 cm is cast into a right circular cone of height 49 cm. Find
the radius of the base of the cone

Answers

Answer:

\(r = 3.74cm\)

Step-by-step explanation:

Given

Hemisphere

\(Radius = 7cm\)

Cone

\(Height = 49m\)

Required

Determine the radius of the cone

First, we calculate the volume (V1) of the hemisphere.

\(V_1 = \frac{2}{3}\pi r^3\)

Substitute 7 for r

\(V_1 = \frac{2}{3}\pi * 7^3\)

\(V_1 = \frac{2}{3}\pi * 343\)

\(V_1 = \frac{686}{3}\pi\)

Volume (V2) of a cone is:

\(V_2 = \frac{1}{3}\pi r^2h\)

Because the lead is cast into a cone, then they have the same volume.

So, we have:

\(\frac{686}{3}\pi = \frac{1}{3}\pi r^2h\)

\(686 = r^2h\)

Substitute 49 for h

\(686 = r^2 * 49\)

Divide both sides by 49

\(r^2 = \frac{686}{49}\)

\(r^2 = 14\)

\(r = \sqrt{14\)

\(r = 3.74cm\)

Hence, the radius of the cone is 3.74cm
