one number is 7 more 3 times another number. the sum is 75. what is the smaller number

Answer:

13

Step-by-step explanation:

The mean of all the numbers is the sum of the numbers divided by the number of numbers.

The sum of all of the numbers is 10 + 14 + 16 + 12 + 14 + 14 + 11 = 91.

We then divide by 7, getting 13.

Answer:

13

Step-by-step explanation:

The mean of a data set is the average value of the set.  

To find the average, we simply need to add all the values and then divide by the number of values.

There are 7 values. So, add all of them and then divide by 7.

[tex]\bar x=\frac{10+14+16+12+14+14+11}{7}[/tex]

Add:

[tex]\bar x=\frac{91}{7}[/tex]

Divide:

[tex]\bar x=13[/tex]

Therefore, our average is 13.  

(Note that the x with the bar on the top is a common way to denote the mean.)

Step-by-step explanation:

Answer:

A) 81

B)-36

C)256

Step-by-step explanation:

A)

We have:

This is the same as:

[tex]=3\times3\times3\times3[/tex]

This equals:

[tex]=81[/tex]

B)

We have:

This one is tricky. Note that the negative is not tied to 6. There's no parentheses. This is the same as saying:

[tex]=(-1)(6)^2[/tex]

Thus, evaluate the square:

Answer: 11.) -6. 12.) 4/5

For the square roots, there should be a plus&minus sign but my keyboard doesn't have that.

13.) 3 14.) 8

explanation: For a square root, you are looking for a number that was multiplied by itself to become the number under the radical.

11 is a bit tricky since there is a negative sign before the radical. 6×6=36 -6 × -6 = 36. It seems they want only the -6 here.

4/5 ×4/5 = 16/25

For cube root, you need the number that is multiplied by itself three times. 3×3×3 = 27 8×8×8=512

Answer:

Step-by-step explanation:

so first the equation for the situation has been given which is

194=1/2x + 2x - 16

now you can just solve since it's a linear equation

194=2.5x -16

take 16 to the other side to get

210=2.5x

solve to get x (adult price)

which is 84

remember the. child's price is 8 less

Answer:

All of them.

Step-by-step explanation:

For rational functions, the domain is all real numbers except for the zeros of the denominator.

Therefore, to find the x-values that are not in the domain, we need to solve for the zeros of the denominator. Therefore, set the denominator to zero:

[tex]x(x-1)(x^2-4)=0[/tex]

Zero Product Property:

[tex]x\neq 0\text{ or }x-1\neq 0\text{ or }x^2-4\neq 0[/tex]

Solve for the x in each of the three equations. The first one is already solved. Thus:

[tex]x-1\neq 0 \text{ or }x^2-4\neq 0\\x\neq 1\text{ or }x^2\neq 4\\x\neq 1 \text{ or }x\neq\pm 2[/tex]

Thus, the values that cannot be in the domain of the rational function is:

[tex]x=-2,0,1,2[/tex]

Click all the options.

Answer:

[tex]\Large \boxed{\mathrm{All \ options}}[/tex]

Step-by-step explanation:

The domain of a function are all possible values for x.

To find the domain of a rational function, we set the denominator equal to 0, and solve for x. Those values of x are not included in the domain, since the denominator of 0 would make the rational function undefined.

[tex]x(x-1)(x^2-4)=0[/tex]

Setting the factors equal to 0.

[tex]x=0 \\ \\ \\\\ x-1=0 \\ \\ x=1 \\ \\ \\ \\ x^2 -4=0 \\ \\ x^2 =4 \\ \\ x=\pm 2[/tex]

The values of x that are not in the domain of the rational function are x=-2, x=1, x=2, and x=0.

Step-by-step explanation:

The closest to the length of one side of the square will be 9.11 meters.

All the sides of a square are congruent. Let a be the side length of the square. Then the area of the square is the square of the side length of the square.

Then the area of the square will be

Area of the square = a² square units

The area of a square is 83 square meters. Then the side length of the square is given as,

A = a²

83 = a²

a = √83

a = 9.11 meters

The closest to the length of one side of the square will be 9.11 meters.

Answer: 4(a - b)

Step-by-step explanation:

If 4 is multiply by the difference of  a and b  then we will have the expression,

4(a-b)

Answer:

x=20

Step-by-step explanation:

Let  = a 30 day period

The first equation is 50 - 2x (because you start with $50 and subtract 2 for each 30 day period)

The second equation is 40-1.5x

Set them equal to each other:  50 - 2x = 40 - 1.5x

Solve for x:

50 - 2x = 40 - 1.5 x

    +2x         +2x

-----------------------

50 = 40 + 0.5 x

-40   -40

-------------------

10 = 0.5 x

20 = x

So there will be 20 30-day periods until the cards will be equal in value.

Check:  After 20 periods, 50 - 2(20) = $10 left

40 - 1.5(20) = also $10 left

Answer:

∠ 1 = 105° , ∠ 2 = 75°

Step-by-step explanation:

Since the lines are parallel then

∠ 2 = 75° ( corresponding angle )

∠ 1 and ∠ 2 are adjacent angles and supplementary, thus

∠ 1 = 180° - 75° = 105°

Answer:            535

                         0.20x+350

Step-by-step explanation:

If Grayson makes $925 in sales he receives $535 and if he makes x sales then he receives $350 +0.2x

A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”

Given here he makes a base income of $350 and he also earns 20% of his sales output and thus if he makes $925, his total income is

= 350+0.2×925

=$535

And let Grayson make x sales in one week then his salary will be

= 350+0.2x

Hence, If Grayson makes $925 in sales he receives $535 and if he makes x sales then he receives $350 +0.2x

Answer:

A, Harry has $27 more.

Step-by-step explanation:

I could be wrong but.

1) debit cards are of your money, if you have $14 in your account it means you have $14 that you can spend without owing anything.

2) credit cards allow you to borrow money with the expectation that you pay it back. So if you have $13 of credit, you owe $13 which I guess could be seen as -$13.

3) the distance between -13 and 14 is 27.

Answer:

y = [tex]\frac{5}{6}[/tex] x + [tex]\frac{8}{3}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 2, 1) and (x₂, y₂ ) = (4, 6)

m = [tex]\frac{6-1}{4+2}[/tex] = [tex]\frac{5}{6}[/tex] , thus

y = [tex]\frac{5}{6}[/tex] x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (4, 6 ), then

6 = [tex]\frac{20}{6}[/tex] + c ⇒ c = 6 - [tex]\frac{20}{6}[/tex] = [tex]\frac{16}{6}[/tex] = [tex]\frac{8}{3}[/tex]

y = [tex]\frac{5}{6}[/tex] x + [tex]\frac{8}{3}[/tex] ← equation of line

Answer:

75.091

Step-by-step explanation:

D. The distribution for town A is positively skewed, but the

distribution for town B is symmetric.

The distribution for town A is positively skewed, but the distribution for town B is symmetric. The correct option is D.

Box plots, also known as box-and-whisker plots, are a way to visualize the distribution of a set of numerical data.

To compare the shapes of the box plots, we need to look at the position of the median, the length of the box, and the length of the whiskers.

In the box plot for town A, the median is closer to the bottom of the box, indicating that the lower half of the data is more spread out than the upper half.

The whisker on the left side of the box plot is longer than the whisker on the right side, which indicates that there are some extreme values on the lower end of the data. This is consistent with a positively skewed distribution.

In contrast, the box plot for town B has a symmetrical box, with the median located near the center.

The whiskers on both sides of the box plot are roughly the same length, indicating that there are no extreme values on either end of the data. This is consistent with a symmetric distribution.

Thus, the correct option is D.
