Question:

The cost of 12 kg sugar is $240 what will be the cost of 3 kg sugar.

Given:

To find?

Answer :

To find cost of 3kg sugar first we have to find cost of 1 kg sugar.

Now Let's find cost of 3 kg sugar

Cost of 3kg sugar = total no of sugar ×Cost of 1 kg sugar

Cost of 3kg sugar = 3×$20

Cost of 3kg sugar = $60

The answer is down below

Answer:

Step-by-step explanation:

Remark

If the horizontal lines are parallel, then 2x +  20 = 3x - 10

Equation

2x + 20 = 3x - 10

Add 10 to both sides

2x + 20 + 10 = 3x

Subtract 2x from both sides

30 = x

2x + 20 = 2*30 + 20 = 80

Answer:

x = 30 and both the angles are 80°

__________________________________________________________

In the given figure,

∠(2x + 20) = ∠(3x - 10)             [corresponding angles]

20 = x - 10                                [subtracting 2x from both sides]

x = 30                                      [adding 10 on both sides]

Value of the angles:

the questions required us to find the measure of a certain ∠XAE, but since we cannot see an ∠XAE in the image provided, we will find the measure of both the angles     [let ∠(2x + 20) = ∠1     and     ∠(3x-10) = ∠2]

Measure of ∠1:

We are given that the magnitude of ∠1 is:

∠1 = 2x + 20

since x = 30

∠1 = 2(30) + 20                             [replacing the value of x]

∠1 = 80°

Measure of ∠2:

We are given that the magnitude of ∠2 is:

∠2 = 3x - 10

since x = 30

∠2 = 3(30) - 10                              [replacing the value of x]

∠2 = 80°

Lisa sold the shares of Chevron indicated above through her discount broker, who charges $28 per transaction.  How much did Lisa receive from the above after the broker took his fee.

Answer:

Trades of Stock in Hewlett-Packard (HPQ) ExxonMobil (XOM) and Chevron CTX)

a. Shares of Hewlett-Packard sold = 6,000 (6K)

b. The total value of all the HP shares sold is $63,780.

c. Total cost of Joan's investment is $64,417.80.

d. Regne's broker received a commission of $3,677.40.

e. Lisa received $760,022.

Step-by-step explanation:

a) Data and Calculations:

Hewlett-Packard (HPQ)    ExxonMobil (XOM)          Chevron CTX)

HPQ 6K10.63 ∨0.23          XOM 3K81.72 ∧ 0.08    CVX 9K84.45 ∨0.22

b) The total value of all the HP shares sold is 6,000 * $10.63

= $63,780

c) Joan's investment:

Investment = $63,780

Broker's commission = 1% = $637.80

Total cost of Joan's investment = $64,417.80 ($63,780 + $637.80)

d) Regne Broker's Commission:

Investment = $245,160 (3,000 * $81.72)

Commission = $3,677.40 ($245,160 * 1.5%)

e) Lisa received from Chevron's stock sale:

Investment = 9,000 * $84.45 = $760,050

Broker's fee = $28

Lisa's receipt = $760,022 ($760,050 - $28)

This question is incomplete, the complete question is;

Given that a Historical Demand for a product is;

Month         Demand

January      12

February    11

March        15

April           12

May            16

June           15

Using a weighted moving average with weights of 0.60 for June, 0.30 for May, and 0.10 for April, find the July forecast.

Answer: the July forecast is 15

Step-by-step explanation:

Given that;

Month       Demand          Weights

January      12

February    11

March        15

April           12                     0.10

May            16                     0.30

June           15                     0.60

July             ?                          ?

Formula for calculating weighted moving average is

Ft = w1A_t-1 + w2A_t-2 ............+ wnA_t-n  

w1, w2, wn is the weight assigned to the period t-1, t-2, t-n respevtively

A_t-1, A_t-2, A_t-n is the demand period t-1, t-2, t-n respevtively

and n is the total number prior periods in the forecast.

so we just substitute our values into the equation

Forecast(July)  = (15 × 0.6) + (16 × 0.30) + ( 12 × 0.10)

= 9 + 4.8 + 1.2

= 15

Therefore the July forecast is 15

C. The balance in her check register will be $116 over the balance on her bank statement.

Answer:

1. 230, 219, 208, 197, 186.

2. Arithmetic, you are subtracting a constant rate, instead of an exponential rate.

3. Finite, the question says the farmer only took 10 trips, infinite would be much, much much more trips.

Step-by-step explanation:

1. The pattern is to subtract 11, so you just do this for 3 more times.

2. Geometric sequences could look something like 230-11=219. The you multiply by a random number like 2, then you subtract 219- (11x2), 219-22=197. This sequence does not do that.

3. It says in the question the farmer only does it for 10 more times.

An algebraic expression in mathematics is an expression which is made up of variables and constants, along with algebraic operations (addition, subtraction, etc.). Expressions are made up of terms.

Given expression

6x-12

Multiplying and dividing with 6

6(x - 2)

Hence, 6(x - 2) is the simplest form of expression 6x-12.

Since both angles are vertical angles, we need to set them equal to each other.

[tex]2(x + 10) = 3x - 30\\\\2x + 20 = 3x - 30\\\\5x + 20 = 30\\\\5x = 50\\\\x = 10[/tex]

The final answer is x = 10.

Answer:

B: Retain the null hypothesis

Step-by-step explanation:

In the relationship between the confidence interval and hypothesis, it is stated that:

When the confidence interval is constructed, all values that fall inside the interval are considered possible values for the parameter that we are estimating while values that fall outside the interval are rejected as they are considered not possible or realistic values.

Now, If the value of the parameter specified by the null hypothesis falls inside the given confidence interval, then we will fail to reject the null hypothesis at the corresponding significance level. However, If the value specified by the null hypothesis doesn't fall inside the given confidence interval, then the null hypothesis can be rejected at the corresponding significance level.

Answer:

[tex]y=2x-10[/tex]

Step-by-step explanation:

We know that the line has a slope of 2 and it passes through the point (3, -4).

So, we can use the point-slope form:

[tex]y-y_1=m(x-x_1)[/tex]

Where m is the slope and (x₁, y₁) is a point.

So, let’s substitute 2 for m and (3, -4) for (x₁, y₁). This yields:

[tex]y-(-4)=2(x-3)[/tex]

Solve for y. Distribute the right:

[tex]y+4=2x-6[/tex]

Subtract 4 from both sides. Therefore, our equation is:

[tex]y=2x-10[/tex]

I believe that the answers are:

a= 65 degrees

b= 80 degrees

Step-by-step explanation:

Purple 80 and b should be the same so 80 degrees

180 - 80 is 100 which is A so a equals 100-35 whis is 65.

Answer:

a=65°, b=100°

Step-by-step explanation:

Hope the answers help! I got confused at first, but take a last look at line BE. Angle EAF is vertically opposite to this line. This means that angle BAF equals 80°. b=100°. a is just 180-80-35, so a=65°.

Answer:

8 should be multiplied in the parenthesis

Step-by-step explanation:

8(9 + x) = 192

72 + 8x = 192

8x = 120

x = 4

Javier made the mistake while expanding the brackets.

Order of operation means simplify the function , expression etc. in given manner.  

To expand a single bracket multiply each term inside the bracket by the term outside the bracket.

8 (9+x) = 192

8*9 + 8*x = 192

72 + 8x = 192

Now, rearranging the above expression

8x = 192 - 72

8x = 120

x = 120/ 8

x = 5

Hence, Javier made the mistake while expanding the brackets.

[tex]a = 10[/tex]

Step-by-step explanation:

[tex]Final\ Velocity\ (v) = 60m/s[/tex]

[tex]Time = 4s[/tex]

Required

Determine the acceleration

This question will be answered using the first equation of motion.

[tex]v = u + at[/tex]

Substitute values for v, u and t

[tex]60 = 20 + 4 * a[/tex]

[tex]60 = 20 + 4 a[/tex]

Subtract 20 from both sides

[tex]60 - 20= 20 -20 + 4 a[/tex]

[tex]40= 4 a[/tex]

Divide both sides by 4
