Answer:

The loss is $120 and the loss percentage is 8%.

Step-by-step explanation:

Given that,

SP of a car = $1,380

CP of a car = $1,500

As CP > SP, it means there is a loss in selling of that car.

Loss = CP - SP

= $1,500 - $1,380

= $120

Loss percentage,

[tex]\%=\dfrac{loss}{CP}\times 100\\\\=\dfrac{120}{1500}\times 100\\\\=8\%[/tex]

Hence, the loss is $120 and the loss percentage is 8%.

Answer:

Step-by-step explanation:

Equation

Let "n" represent the number. Then more indicates addition, and times indicates multiplication. With that said, the answer is 4 + 3n.

Dale's Money

Given: $44 in total

44 ÷ 2 (To know how much they have  equally)

22

22 ÷ 3 (Then you divide by 3 because Brandon has 3 times his, the opposite of multiplication is division.)

7.3

Therefore, Dale has $7.3¢

Brandon's money

Given: 4 + 3n. Dale has 7.3

Solve: 7.3 × 3 ( Since Brandon has four more than 3 times the amount of money that Dale has, multiply that and 3)

21.9 (Then add four because Brandon has four more...)

25.9

Therefore, Brandon has $25.9¢

The amount that Brandon and Dale have is $34 and $10, respectively.

An equation is formed when two expressions are equated with each other with the help of an equal sign.

Let the amount of money that Brandon has be x, and Dale has be y.

As it is given that the sum of the total amount they both had is $44. therefore, the equation that can represent the total amount both of them had is

[tex]x + y = \$44[/tex]

Now, according to the first statement, Brandon has four more than 3 times the amount of money that Dale has. therefore, the equation can be represented as,

[tex]x = 4 + 3y[/tex]

Further, as got the two-equation solving the two equations. We have the value of x, therefore, substitute the value of x in the first equation,

[tex]x+y = 44\\\\(4 + 3y )+y= 44\\\\4+4y=44\\\\4y = 40\\\\y = 10[/tex]

Now, substitute the value of y in the second equation we get,

[tex]x = 4 + 3y\\\\x = 4 + 3(10)\\\\x = 34[/tex]

Hence, The amount that Brandon and Dale have is $34 and $10, respectively.

Answer:

Prism A:

[tex]Area = 288cm^2[/tex]

Prism B:

[tex]Area =250cm^2[/tex]

Step-by-step explanation:

Given

See attachment for prisms

[tex]Height(h) = 10cm[/tex]

Required

Determine the surface area of both prisms

Prism A is triangular and as such, the surface area is:

[tex]Area = 2 * A_b + (a + b + c) * h[/tex]

Where

[tex]A_b = \sqrt{s * (s - a) * (s -b) * (s - c)}[/tex]

and

[tex]s = \frac{a + b + c}{2}[/tex]

Such that a, b and c are the lengths of the triangular sides of the prism.

From the attachment;

[tex]a = 8; b =6; c =10[/tex]

So, we have:

[tex]s = \frac{a + b + c}{2}[/tex]

[tex]s = \frac{8 + 6 + 10}{2}[/tex]

[tex]s = \frac{24}{2}[/tex]

[tex]s = 12[/tex]

Also:

[tex]A_b = \sqrt{s * (s - a) * (s -b) * (s - c)}[/tex]

[tex]A_b = \sqrt{12 * (12 - 8) * (12 - 6) * (12 - 10)}[/tex]

[tex]A_b = \sqrt{576}[/tex]

[tex]A_b = 24[/tex]

So:

[tex]Area = 2 * A_b + (a + b + c) * h[/tex]

[tex]Area = 2 * 24 + (8 + 6 + 10) * 10[/tex]

[tex]Area = 288cm^2[/tex]

Prism B is a rectangular prism. So, the area is calculated as:

[tex]Area = 2 * (ab + bh + ah)[/tex]

From the attachment

[tex]a = b = 5[/tex]

[tex]h =10[/tex]

So:

[tex]Area =2 * (5 * 5 + 5 * 10 + 5 * 10)[/tex]

[tex]Area =250cm^2[/tex]

Answer:

Step-by-step explanation:

Answer:

0.64%.

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Mean of 75 grams and a standard deviation of 22 grams.

This means that [tex]\mu = 75, \sigma = 22[/tex]

Sample of 144:

This means that [tex]n = 144, s = \frac{22}{\sqrt{144}} = 1.8333[/tex]

More than 80 or less than 70:

Both are the same distance from the mean, so we find one probability and multiply by 2.

The probability that it is less than 70 is the pvalue of Z when X = 70. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{70 - 75}{1.8333}[/tex]

[tex]Z = -2.73[/tex]

[tex]Z = -2.73[/tex] has a pvalue of 0.0032

2*0.0032 = 0.0064.

0.0064*100% = 0.64%

The probability is 0.64%.

Answer:

30 = 80 %

40= 20 %

Step-by-step explanation

I'm sorry for not writing how to do it but it's something like if 30 = 100 then if we had 40 occupying 20 percent of that acid then we will get 32 percent

The number of liters of each solution should be mixed to obtain 65 liters of 32% acid solution is 52 liters and 13 liters respectively.

A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.

Let x be 30% solution of acid and y be 40% solution of acid.

Total quantity of solution is 65 liters.

Now, x+y=65 ----------(i)

Number of liters of solution should be mixed to obtain 65 liters of 32% acid solution.

So, the equation is 30% of x+40% of y=32% of 65

0.30x+0.40y=0.32×65

0.30x+0.40y=20.8 ----------(ii)

From equation (i), x=65-y

Substitute x=65-y in equation (ii), we get

0.30(65-y)+0.40y=20.8

19.5-0.30y+0.40y=20.8

0.10y=20.8-19.5

0.10y=1.3

y=1.3/0.1

y=13

Substitute y=13 in equation (i), we get x=52

Therefore, the number of liters of each solution should be mixed to obtain 65 liters of 32% acid solution is 52 liters and 13 liters respectively.

5x+4         -5x-6

m=5           m=-5

Answer:

Start: x = 141°

141° and x are alternate interior angles and congruent because the lines are parallel

Go left: x = 39°

39° and x are corresponding angles, and therefore congruent

Go down: x = 139°

180 - 41 = 139, the angle next to 41 and x are corresponding angles

Go left: x = 98°

180 - 82 = 98, the angle next to 82 and x are corresponding angles

Go down: x = 102°

102° and x are vertical angles and therefore congruent

Go right: x = 50°

180 - 130 = 50, the angle next to 130 and x are corresponding angles

Go down: x = 74°

corresponding angles

Go right: x = 83°

corresponding angles

Go right: x = 95°

corresponding angles

Go up: x = 18°

corresponding angles

Go left: x = 166°

180 - 14 = 166, consecutive interior angles are supplementary (I'm confused? none of the answers have it but they're definitely consecutive interior...)
