25*4 =100 so if 25% is one of 4 parts of 100% than 36: 3 is 12 so that means that 12 is one of 3 parts of 36. So just add 12 to 36 to make it 4 parts 36+12=48 so originally they were 48$

Let

x-------> the original price of the bed sheets

we know that

Nancy purchased some bed sheets for $ $36$ they were on sale $25$ % off

$100$ %- $25$ %= $75$ %

$75$ %= $0.75$

$0.75*x=36\\ x=36/0.75\\ x=48$

therefore

the answer is

the original price of the bed sheets was $ $48$

What is the first term of the geometric sequence presented in the table below?

Vikentia [17]

To get the first term of the geometric sequence we proceed as follows;
The formula for the arithmetic sequence is:
an=ar^(n-1)
the 5th term is 176, thus;
176=ar^(5-1)
176=ar^4........i

the 7th term is 704, thus;
704=ar^(7-1)
704=ar^6........ii
from i
a=176/r^4
from ii
a=704/r^6
hence;
176/r^4=704/r^6
cross-multiplying the expression we get;
176r^6=--704r^4
dividing both sides by 176r^4 we get:
r^2=4
thus
r=sqrt4
r=2
therefore the first term will be:
a=176/r^4
a=176/2^4
a=11

A composite figure is divided into two congruent trapezoids, each with a height of 4 cm.

lidiya [134]

Answer:

The area of this composite figure is $64\ cm^{2}$

Step-by-step explanation:

we know that

If the composite figure is divided into two congruent trapezoids, then the area of the composite figure is equal to the area of one trapezoid multiplied by two

The area of the composite figure is

$A=2[\frac{1}{2}(b1+b2)h]$

$A=(b1+b2)h$

substitute the values

$A=(6+10)4$

$A=64\ cm^{2}$

Which is the correct way to solve the given equation

Karolina [17]

Option 2. $x = \frac{4 \pm \sqrt{(-4)^{2}-4 (1)(-21)}}{2 (1)}$ shows the correct way to use the quadratic formula to solve the given equation.

Step-by-step explanation:

Step 1:

For an equation of the form $ax^{2} +bx+c=0$ the solution is $x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}$ .

Here a is the coefficient of $x^{2}$ , b is the coefficient of x and c is the constant term.

$x^{2} -4x=21$ can also be written as $x^{2} -4x-21=0.$

Comparing $x^{2} -4x-21=0$ with $ax^{2} +bx+c=0$ , we get that a is 1, b is -4 and c is -21.

To get the solution, we substitute the values of a, b, and c in $x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}$ .

Step 2:

Substituting the values, we get

$x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}= \frac{-(-4) \pm \sqrt{(-4)^{2}-4 (1)(-21)}}{2 (1)}.$

$\frac{-(-4) \pm \sqrt{(-4)^{2}-4 (1)(-21)}}{2 (1)} = \frac{4 \pm \sqrt{(-4)^{2}-4 (1)(-21)}}{2 (1)}.$

This is option 2.
