help me with this mathematic problem

Answer:

6.966

Step-by-step explanation:

•Mark how many you have in the d.p

•If there is two or more add them up

•Multiply like normal given numbers

•Write where the decimal point is to be

Hope that helps

The answer you are looking for is 6.966. You multiply the numbers as normal, the place the decimal based off of how many numbers are behind the 2 decimal points given. 1.29 has 2 numbers behind the decimal, and 5.4 has 1. 1 + 2 = 3, so from the right of the last number on the right side, you move the decimal 3 places.

Here's an image to show you how I solved the problem.

I hope this helps!!

Answer:

Blue:  32.4 mpg

Red:  28 mpg

The Blue car will travel farther on a gallon of gasoline

Step-by-step explanation:

Blue: 40.5/1.25=32.4 mpg

Red: (22 2/5)/(4/5) =22.4/0.8=28 mpg

Answer:

Step-by-step explanation:

2x+6 > -14

Subtract 6 from both sides

2x > -20

Divide both sides by 2

x > -10

The solution of the inequality 2x + 6 > - 14 will be greater than the negative 10.

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

Six more than twice a number is greater than negative fourteen.

Let x be the number. Then the equation will be

2x + 6 > - 14

Simplify the inequality, then the value of x will be

2x > - 20

x > - 10

The solution of the inequality 2x + 6 > - 14 will be greater than the negative 10.

Answer:

[tex]x = 27[/tex]

Step-by-step explanation:

A shape exterior angles add up to 360.

All of these angles are exterior angles so we can add up all of them to and set it equal to 360 to find x.

[tex]3x + 4x + 2x + 40 + x + 50[/tex]

[tex]10x + 90 = 360[/tex]

[tex]10x = 270[/tex]

[tex]x = 27[/tex]

I take it as you want to learn about the formula.

The quadratic formula is a formula where you can solve x for any quadratic equation in form  ax^2+bx+c=0.

The formula is x= [tex]\frac{-b+-\sqrt{b^2-4ac}}{2a}[/tex].

The +- means + or - for the 2 solution in each equation.

*All above information is what you need to know about the quadratic formula and solve for answer, but I will go a step further in my answer to prove the quadratic formula always work.

[tex]0=ax^2+bx+c[/tex]

[tex]0=(ax+\frac{b}{2})^2-\frac{b^2}{4}+c[/tex] (This step is completing the square)

[tex](ax+\frac{b}{2})^2=\frac{b^2}{4}-c[/tex]

[tex](2ax+b)^2=b^2-4ac[/tex]

[tex]2ax+b=+or-\sqrt{b^2-4ac}[/tex]

[tex]2ax=-b+ or -\sqrt{b^2-4ac}[/tex]

[tex]x=\frac{-b+-\sqrt{b^2-4ac}}{2a}[/tex]

This is my way of proving this formula although there are many other ways to do it too, if there is any questions, feel free to ask me in the comment :-).

Answer:

y = 4x + 12

Step-by-step explanation:

slope-intercept form is y = mx + b, where m = slope and b = y-intercept.

since you're given the values for m and b, all you need to do is plug those into the equation for slope-intercept form.

plug in 4 for m.

y = mx + b ⇒ y = 4x + b

plug in 12 for b.

y = 4x + b ⇒ y = 4x + 12

it doesn't matter which one you plug in first as long as you plug the value in for the correct variable.

the equation of your line in slope-intercept form is y = 4x + 12. i hope this helps! have a great day <3

Answer:

B. -3

Step-by-step explanation:

f(x) = 3x - 15

f(4) means x=4, so you want to plug 4 into the equation.

f(4) = 3(4) - 15

f(4) = 12 - 15

f(4) = -3

Answer:

B

Step-by-step explanation:

f(4) has the same meaning (for this question ) as x = 4

Let x = 4

f(4) = 3*4 - 15

f(4) = 12 - 15

f(4) = - 3

Answer: P = 2716.3448786 or about 2700

Step-by-step explanation:

The amount that need to invest, to the nearest hundred dollar is to be considered as the 2,700.

Since

The interest rate be like = 1.5% = 1.5% / 4 = 0.38%

The time period = 13 * 4 = 52

The future value = $3,300

The PMT is = $0

Now the following formula is used;

So,

= -PV(RATE,NPER,PMT,FV,TYPE)

After applying it, the present value should be $2,700

Answer:

[tex]y=\frac{5+8x}{10} , x=x[/tex]

Step-by-step explanation:

y-0.8x=0.5

y*10-0.8x*10=0.5*10

10y-8x=5

10y-8x+8x=5+8x

10y/10=5/10+8x/10

y=5+8x/10

5*5+8x/10-2.5

8x+5/2-2.5=4x

y=5+8x/10, x=x

Answer:

$0.98

Step-by-step explanation:

Given data

Cost of sinuses apples = $9.8 for 10 pound

We want to find the cost per pound

Hence

if 10 pounds cost $9.8

  1 pound will cost x

cross multiply

x= 9.8/10

x= $0.98

Hence a pound will cost $0.98

Answer: y = 11.25

Step-by-step explanation:

Mi espanol es terrible :l

Todos los angulos terminaran acompletando 90° grados

Entonces hagamos una ecuacion

3y + 4y + y = 90

8y = 90

Divide por 8

y = 11.25

Esta parte no es necesaria

Para ver si es verdad hagamos el math

3(11.25) = 33.75

4(11.25) = 45

y = 11.25

33.75 + 45 + 11.25 = 90
