I will show you how to do #1.
So 25% is equal to 1/4 and 56 is the whole what you are finding is the part so to set it up. You do this:
1/4=x/56
Then you solve for x and to do this you can do cross-multiply and divide which is 56 times 1=56 and 56 divide by 4= 14
So the answer to #1 is 14 which is the part
So to solve these you do percent/100=part/whole
So in this problem 25 was the percent over 100 and I simplified making it 1/4 and then I put 1/4 was equal to x/56 because we knew the whole and not the part and the part was x
If that makes any sense.

Find the value of x that make it true

lesantik [10]

Answer:

Step-by-step explanation:

1). 10 = $\frac{1+7x}{7+x}$

10(7 + x) = 1 + 7x

70 + 10x = 7x + 1

10x - 7x = 1 - 70

3x = -69

x = -23

2). 0.2 = $\frac{6+2x}{12+x}$

0.2(12 + x) = 6 + 2x

2.4 + 0.2x = 6 + 2x

2.4 - 6 = 2x - 0.2x

1.8x = -3.6

x = -2

3). 0.8 = $\frac{x}{x+0.5}$

0.8(x + 0.5) = x

0.8x + 0.4 = x

x - 0.8x = 0.4

0.2x = 0.4

x = 2

4). 3.5 = $\frac{4+2x}{0.5-x}$

3.5(0.5 - x) = 4 + 2x

1.75 - 3.5x = 4 + 2x

-3.5x - 2x = 4 - 1.75

-5.5x = 2.25

x = - $\frac{2.25}{5.5}$

x = - $\frac{9}{22}$

What is 20% of 50?

vova2212 [387]

Answer:

C.) percent= 20%, Amount=unknown, Base =50

Step-by-step explanation:

The percent is the percent, so 20% is the percent.

The number you take the percent of is the base. The base is 50.

Once you calculate the percent of the base, you get the amount.

We are given the percent, 20%, the base, 50, but not the amount.

Segment AB has endpoints with coordinates A: (-4, -7) and B: (8, -4). Determine the value of the x-coordinate of the interior po

Nadusha1986 [10]

Answer:

≈ 3.4 

Step-by-step explanation:

Coordinates of the point that divide segment with endpoints A( $x_{1}$ , $y_{1}$ ) and B( $x_{2}$ , $y_{2}$ ) in a ratio a : b are

$\frac{bx_{1} +ax_{2} }{a+b}$ , $\frac{by_{1} +ay_{2} }{a+b}$ )

A(- 4, - 7)

B(8, - 4)

Ratio 8 : 5

x-coordinate is $\frac{5(-4)+8(8)}{8+5}$ = $\frac{44}{13}$ ≈ 3.4

The Laplace Transform of a function f(t), which is defined for all t > 0, is denoted by L{f(t)} and is defined by the imprope

lesya692 [45]

(1) D

$L_s\left\{t\right\} = \displaystyle\int_0^\infty te^{-st}\,\mathrm dt$

Integrate by parts, taking

$u = t \implies \mathrm du=\mathrm dt$

$\mathrm dv = e^{-st}\,\mathrm dt \implies v=-\dfrac1se^{-st}$

Then

$L_s\left\{t\right\} = \displaystyle \left[-\frac1ste^{-st}\right]\bigg|_{t=0}^{t\to\infty}+\frac1s\int_0^\infty e^{-st}\,\mathrm dt$

$L_s\left\{t\right\} = \displaystyle \frac1s\int_0^\infty e^{-st}\,\mathrm dt$

$L_s\left\{t\right\} = \displaystyle -\frac1{s^2}e^{-st}\bigg|_{t=0}^{t\to\infty}$

$L_s\left\{t\right\} = \displaystyle \boxed{\frac1{s^2}}$

(2) A

$L_s\left\{1\right\} = \displaystyle\int_0^\infty e^{-st}\,\mathrm dt$

$L_s\left\{1\right\} = \displaystyle\left[-\frac1se^{-st}\right]\bigg|_{t=0}^{t\to\infty}$

$L_s\left\{1\right\} = \displaystyle\boxed{\frac1s}$
