By what percent will a fraction decrease if its numerator is decreased by 50% and its denominator is decreased by 25%?

ioda

Answer:

The fraction will decrease $33.33\%$

Step-by-step explanation:

Let

x/y ----> the fraction

we know that

100%-50^=50%=50/100=0.50

100%-25%=75%=75/100=0.75

substitute

$\frac{x}{y}*\frac{0.50}{0.75} =\frac{2}{3}(\frac{x}{y})$

therefore

The percent that the fraction will decrease is equal to

$(1-\frac{2}{3})*100=33.33\%$

Find the vol of this prism

polet [3.4K]

Answer:

V = 396 cm³

Step-by-step explanation:

the volume (V) of the prism is calculated as

V = Ah ( A is the area of the triangular face and h the height of prism )

A = $\frac{1}{2}$ bh ( b is base and h perpendicular height )

here b = 9, h = 8 , then

A = $\frac{1}{2}$ × 9 × 8 = 4.5 × 8 = 36 cm² , so

V = 36 × 11 = 396 cm³

A student used f(x)=5.00(1.012)xf(x)=5.00(1.012)x to show how the balance in a savings account will increase over time. What doe

taurus [48]

Answer:

5.00 is the value of the initial balance (i.e. when time is 0) in the savings account.

Step-by-step explanation:

We have the function, $f(x)=5.00(1.012}^x$ which represents the balance in the savings account.

Now, if we substitute x= 0, we have,

$f(x)=5.00(1.012}^x$ implies $f(0)=5.00(1.012}^0$

As, 'any number with power 0 is equal to 1 i.e. $x^0=1$ '.

We get,

$f(0)=5.00(1.012}^0$ implies $f(0)=5.00\times 1$ i.e. f(0)= 5.00

Thus, we see that,

5.00 is the value of the initial balance (i.e. when time is 0) in the savings account.

Select the two statements that are true about the equation y−56=4(x+5)y-56=4(x+5).

Sergio [31]

The correct answers are:

The slope of the line is 4.

A point on the line is (−5, 56)

Step-by-step explanation:

Given equation is:

$y-56=4(x+5)$

The slope-intercept form is:

$y-y_1=m(x-x_1)$

Comparing both equations we get

m = 4

$y-56=y-y_1\\y_1 = 56\\x+5 = x-x_1\\x_1=-5$

The point is (-5,56)

So, the correct answers are:

The slope of the line is 4.

A point on the line is (−5, 56)
