Answer:

14.8

Step-by-step explanation:

42.79-27.99=14.8

When subtracted $27.99 from $42.79, we get $14.8.

Subtraction is one of the most basic arithmetic operation in mathematics. Subtraction implies taking away one value from the another. Subtract x from y implies y - x. The number after from comes first. On subtraction, the sign (positive/negative) of the greater number of the two numbers given, is the sign (positive/negative) of the answer. Subtraction is also called as difference.

Given in the question,

Take $27.99 from $42.79

This implies,

= 42.79 - 27.99

= 14.8

Answer:

Step-by-step explanation:

The apothem of the square is four time lower than the area squared. Thus, to do this, we must use the formula A = s^2

Using this, we do A = s^2, and replace s for 12. Doing exponents first following order of operations (PEMDAS), we get 144. Now, that's only one side of the square. Since the square is 4 sides, we must multiply by four. Thus, your answer is (144 * 4) = 576 cm^2.

Answer: 576 cm squared.

Answer: D) 12 units

Explanation:

There are 12 spaces between T and S.

You can count the spaces out, or subtract and use absolute value.

You could use the distance formula, but it's a bit overkill in this situation. The distance formula is only ever needed whenever we don't have horizontal or vertical line segments.

Edit: The solution has been corrected to the correct value.

Answer:

0.25 and 25%

Step-by-step explanation:

25% is the same as 1/4

0.25 is the same as 1/4

Answer:

1/4 = 0.25

1/4 = 25%

1/4 or 1 divided by 4 equals 0.25 (decimal) and 25% (percentage).

Answer:

(7, 3)

Step-by-step explanation:

We can solve this system using elimination. In this scenario, we can eliminate x by subtracting the two equations:

x-3y=-2

x+3y=16

-3y-3y=-2-16

-6y=-18

Divide both sides by -6

y=3

Plug 3 back in for y to solve for x:

x-3(3)=-2

x-9=-2

Add 9 to both sides

x=7

(x, y) = (7, 3)

Answer:

$1,110

Step-by-step explanation:

You have to use the interest formula to calculate how much each brother will have after a year.

A = P(1+r)^t

A = future/ending value

P = principle

R = interest rate

T = time (given in years)

Charles = 30,000(1+.025)^1 = 30,750

Brian = 30,000(1+.062)^1 =31,860

31,860-30,750=1,110

Brian will have $1,110 more than Charles after 1 year

[tex]-\dfrac{14}{15}-\dfrac{1}{3}v[/tex]

Step-by-step explanation:

Given expression:

[tex]-\dfrac{6}{5}-\dfrac{2}{3}v+\dfrac{4}{15}+\dfrac{1}{3}v[/tex]

Collect like terms:

[tex]\implies \dfrac{4}{15}-\dfrac{6}{5}+\dfrac{1}{3}v-\dfrac{2}{3}v[/tex]

Make the denominators for the like terms the same:

[tex]\implies \dfrac{4}{15}-\dfrac{6 \times 3}{5 \times 3}+\dfrac{1}{3}v-\dfrac{2}{3}v[/tex]

[tex]\implies \dfrac{4}{15}-\dfrac{18}{15}+\dfrac{1}{3}v-\dfrac{2}{3}v[/tex]

Combine like terms:

[tex]\implies \dfrac{4-18}{15}+\dfrac{1-2}{3}v[/tex]

Step-by-step explanation:

Original equation:

subtract 12 from both sides:

[tex]\implies \sqrt{1-4x}=3[/tex]

square both sides:

[tex]\implies 1-4x=9[/tex]

subtract 1 from both sides:

[tex]\implies -4x=8[/tex]

divide both sides by -4:

[tex]\implies x=-2[/tex]

[tex]\\ \tt\rightarrowtail 12+\sqrt{1-4x}=15[/tex]

[tex]\\ \tt\rightarrowtail \sqrt{1-4x}=3[/tex]

Answer:

15

Step-by-step explanation:

In the function f(x), x is the variable. So, whatever is in the parentheses, replacing x, should replace x throughout the entire function. So, to find f(4) simply plug in 4 for x.

f(4) = 4^2 - 4 + 3

f(4) = 4^2 - 1

f(4) = 16 - 1

f(4) = 15

Answer:

f(4) = 15

Step-by-step explanation:

Substitute 4 for x and solve for f(4).

[tex]f(x)=x^2-x+3\\f(4)=(4)^2-4+3\\f(4)=16-4+3\\f(4)=15[/tex]

Answer:

[tex]\displaystyle 3x - 2y = 13\:or\:y = 1\frac{1}{2}x - 6\frac{1}{2} \\ [0, -6\frac{1}{2}] \\ 1\frac{1}{2} = m[/tex]

Step-by-step explanation:

First, figure the rate of change [slope] out:

[tex]\displaystyle \frac{-y_1 + y_2}{-x_1 + x_2} = m \\ \\ \frac{-1 + 16}{-5 + 15} = \frac{15}{10} = 1\frac{1}{2} \\ \boxed{1\frac{1}{2} = m}[/tex]

Now locate the initial value [y-intercept] by plugging an ordered pair into the slope-intercept formula. It does not matter which ordered pair you use:

_______________________________________________

[tex]\displaystyle y = mx + b[/tex]

16 = 1½[15] + b >> [tex]\displaystyle 16 = 22\frac{1}{2} + b; -6\frac{1}{2} = b[/tex]

OR

1 = 1½[5] + b >> [tex]\displaystyle 1 = 7\frac{1}{2} + b; -6\frac{1}{2} = b[/tex]

[tex]\displaystyle [0, -6\frac{1}{2}][/tex]

_______________________________________________

You now have your initial value. All that is left is to write the equation of this line, which can be written two ways:

> Slope-Intercept Form

[tex]\displaystyle y = 1\frac{1}{2}x - 6\frac{1}{2}[/tex]

> Standard Form [tex]\displaystyle [Ax + By = C][/tex]

y = 1½x - 6½

- 1½x - 1½x

___________

–1½x + y = –6½ [We CANNOT leave the equation this way, so multiply by –2 to eradicate the fraction\denominatour (if you wrote the equation as mixed numbers\if you wrote the equation as improper fractions).]

–2[–1½x + y = –6½]

[tex]\displaystyle 3x - 2y = 13[/tex]

With that, you have defined all the information.

[tex]\displaystyle -3x + 2y = -13[/tex]

*About this equation, INSTEAD of multiplying by –2, you multiply by its oppocite, 2. Now, you can leave it like this, but UNIVERSALLY, the A-term is positive, so you must multiply the negative out as well.

Inequalities are used to represent unequal expressions

The solution to the system of inequalities is (-1,1)

The system of inequalities is given as:

y > x + 2 and

y < 2x + 3

To do this, we start by plotting the graphs of the two inequalities

y > x + 2 and  y < 2x + 3

See attachment for the graph

From the attached graph, both lines meet at (-1,1)

Hence, the solution to the system of inequalities is (-1,1)

Answer:

Jami has $13.5

Mami has $18.5

Step-by-step explanation:

Let j = Jami's money

     m - Mami's money

j + m = 32

j = m -  5 (Since Jami basically has 5 less than Mami)

Substitute the j in the top equation

m - 5 + m = 32

2m - 5 = 32

Add 5 to both sides

2m - 5 = 32

2m = 37

Divide both sides by 2

2m/2 = 37/2

m = 37/2 = 18.5

Now plug the new m into the bottom equation

j = 18.5 - 5

j = 13.5

Answer:

Step-by-step explanation:

We have been given that human body temperatures have a mean of 98.20° F and a standard deviation of 0.62°. Sally's temperature can be described by z = -1.5.

To find Sally's temperature we will use z-score formula.

, where  = Mean, = Standard deviation.

Let us substitute our given values in z-score formula.

Multiply 0.62 to both sides of equation.

Add 98.20 to both sides of equation.

Therefore, Sally's temperature will be 97.27 degrees Fahrenheit.
