Can someone please help me solve and explain?

1 answer:

8 0

The Answer would be 100
My reason:
First you see how many times you can take away 10 from 120 to get 0 and the answer is 12. Then you do 12 for the amount of times to increase your entry fee times 5 for the amount of increase and that is 60, lastly you do 60 + 40 which was our beginning number and you get 100.

Answer:

The equation in point-slope is $\mathbf{y+5=3(x-6)}$

Step-by-step explanation:

We need to write the point-slope form of the equation of the line passing through the point (6,-5) and perpendicular to the line $y=-\frac{1}{3}x+4$

The general form of point-slope is; $y-y_1=m(x-x_1)$

where m is slope and $(x_1,y_1)$ is the point

We need to calculate slope.

We are given equation of line $y=-\frac{1}{3}x+4$ that is perpendicular to the required line.

The equation is given in slope-intercept form $y=mx+b$ where m is slope.

Comparing both equations we get m= -1/3

But we know that when lines are perpendicular their slopes are opposite reciprocal of each other i.e $m=-\frac{1}{m}$

So, slope of required line is m = 3 (opposite reciprocal of -1/3)

Now, the equation in point-slope form having slope m=3 and point (6,-5) is

$y-y_1=m(x-x_1)\\y-(-5)=3(x-6)\\y+5=3(x-6)$

So, The equation in point-slope is $\mathbf{y+5=3(x-6)}$

Can someone help with my homework?

Len [333]

Answer:

1a) $-\frac{15}{4}$

1b) $\frac{95}{33}$

2a) $-84$

2b) 1

3a) $\frac{171}{550}$

3b) $4\frac{2}{7}$

Step-by-step explanation:

For the first equation, let's use $\frac{-a}{b} =\frac{a}{-b} =-\frac{a}{b}$ to right a new fraction.

Step 1- Reduce the fraction with 4.

$-\frac{\frac{12/4}{4/4} }{\frac{4}{5} } = -\frac{3}{\frac{4}{5} }$

Step 2- Simplify the complex fraction(LCD or Least Common Denominator).

$-\frac{3}{\frac{4}{5} } = -\frac{15}{4}$

An alternative form for this fraction is $-3\frac{3}{4} or -3.75$ .

For the second equation..

Step 1- Convert the mixed number to an improper fraction.

$\frac{6\frac{3}{9} }{\frac{11}{5} } = \frac{\frac{57}{9} }{\frac{11}{5} }$

Step 2- Simplify the complex fraction.

$\frac{\frac{57}{9} }{\frac{11}{5} } = \frac{95}{33}$

An alternative form for this fraction is $2\frac{29}{33} or 2.87$ .

For the third equation use $\frac{-a}{b} =\frac{a}{-b} =-\frac{a}{b}$ ...

Step 1- Simplify the complex fraction(LCD).

$-\frac{7}{\frac{1}{12} } = -84$

For the fourth equation...

Write the fraction as a division.

$\frac{12}{8}$ ÷ $\frac{3}{2}$

To divide a fraction, multiply by the reciprocal of that fraction.

$\frac{12}{8} *\frac{2}{3} = \frac{12*2}{8*3}$

Reduce the fraction with 3.

$\frac{4*2}{8}= \frac{4}{4} = 1$

For the fifth equation...

Convert the mixed number to an improper fraction.

$\frac{-1\frac{8}{11} }{-5\frac{5}{9} } = \frac{-\frac{19}{11} }{-\frac{50}{9} }$

Reduce the fraction with -1, this eliminates the negative sign.

Simplify the complex fraction.

$\frac{\frac{19}{11} }{\frac{50}{9} } = \frac{171}{550}$

An alternative form for this fraction is 0.3109.

For the sixth equation..

Write the fraction as a division.

$\frac{3}{7}$ ÷ $\frac{1}{10}$

To divide by a fraction, multiply by the reciprocal of that fraction.

$\frac{3}{7}$ ×10= $\frac{3*10}{7}$

Multiply the numbers.

$\frac{3*10}{7} = \frac{30}{7}$

Alternative form of this fraction is $4\frac{2}{7}$ or 4.285714.

Hope this helps! :)

The radius of a cylinder water tanks 6' in its hide is 9' what is The volume of the tank

EleoNora [17]

Answer:

6^6 = 36 (squared my radius in order to find the area of one circle)

36 x 3.14(multiplied my radius by pi to find the area) = 113.04

Now we multiply the area of one circle with the height since it is a prism throughout the whole shape.

113.04 x 9 = 1,017.36 in^3 is your answer.

Step-by-step explanation:

Formula of area of a circle:

pi(3.14 or 22/7 depending on what they tell you to use for pi) x radius squared(your radius is half of your diameter or given radius, your radius should be squared in order to find the area).

πr^2

pi x radius^2(radius being squared)
