Answer:

$325

Step-by-step explanation

78% is 234

x is 100%

cross multiply

[tex]\frac{234}{72}[/tex] = [tex]\frac{x}{100}[/tex]

234 × 100 = 72x

23400 = 72x

23400÷72 =72x ÷72

325 = x

The value of the original price of the sofa would be $325.

Used the concept of percentage that is,

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating the hundredth part of any quantity is called a percentage.

Given that,

At a sale this week, a sofa is being sold for $234.

And, This is a 28% discount from the original price.

Let us assume that the original price = x

Hence, the given condition is written as,

[tex]x - (28\% \ \text{of } x) = 234[/tex]

Solve for x,

[tex]x - (0.28 x) = 234[/tex]

[tex]0.72x = 234\\[/tex]

Divide both sides by 0.72,

[tex]x = \dfrac{234}{0.72}[/tex]

Therefore, the original price would be,

[tex]x = \$325[/tex]

The distance between the centre and any point satisfying the circle is its radius ~

Hence, the distance between the points is equal to length of radius.

[tex]\qquad \sf  \dashrightarrow \: r = \sqrt{(4 - 1) {}^{2} + (9 - 5) {}^{2} } [/tex]

[tex]\qquad \sf  \dashrightarrow \: r = \sqrt{(3) {}^{2} + (4) {}^{2} } [/tex]

[tex]\qquad \sf  \dashrightarrow \: r = \sqrt{9 + 16} [/tex]

[tex]\qquad \sf  \dashrightarrow \: r = \sqrt{25} [/tex]

[tex]\qquad \sf  \dashrightarrow \: r = 5[/tex]

As we know, equation of a circle is :

[tex] \qquad \sf(x - h) {}^{2} + (y - k) {}^{2} = {r}^{2} [/tex]

where,

Hence, equation of our required clrcle is :

[tex] \qquad \sf(x -1 ) {}^{2} + (y - 5) {}^{2} = {5}^{2} [/tex]

The radius of the circle that has center (1,5) and contains the point (4,9)  is 5 units

The center of the circle is given as:

Center (a,b) = (1,5)

The point on the circle is given as:

Point (x,y) = (4,9)

The radius is calculated using the following distance equation

[tex]r = \sqrt{(x - a)^2 + (y - b)^2}[/tex]

So, we have:

[tex]r = \sqrt{(4 - 1)^2 + (9 - 5)^2}[/tex]

Evaluate the exponents

[tex]r = \sqrt{25}[/tex]

Take the square root of 5

r = 5

Hence, the radius of the circle is 5 units

Answer:

A supplementary angle is an angle that forms 180°. To put into simpler words, it's the angle that makes a straight line.

A complementary angle is an angle that makes a 90° angle or a right angle.

An acute angle is an angle that is less than 90°.

An obtuse angle is an angle that is between 90 & 180 degrees.

A reflex is one that makes a 270° angle.

And finally you have a full/complete angle which makes a 360° angle

cross multiply so 4 simplifies to 2 and 2 simplifies to 1

15/2 × 1/1 = 15/2

15/2 = 7½ ft

Answer:

L = (6u + 5)m ; W = (2u-3)m

Step-by-step explanation:

Given;

Area of the rectangular vegetable garden, A = (12u² - 8u - 15)m²

Let the length of the rectangular vegetable garden = L

Let the width of the rectangular vegetable garden = W

A = L x W

Factorize the given area;

= 12u² - 8u - 15

= 12u² -18u + 10u - 15

= 6u(2u - 3) + 5(2u - 3)

= (6u + 5)(2u-3)

Thus, L = (6u + 5)m     and     W = (2u-3)m

Answer:

30 gram doses

Step-by-step explanation:

First, turn the fractions into decimals.

1/4 gram to .25 gram

7 1/2 gram to 7.5 gram

Then, divide 7.5 total grams by the .25 grams for each dose.

7.5/.25 = 30

Therefore, you can obtain 30 1/4 gram doses from a 7 1/2 gram vial of medication.

Given:

Weight of the vial = [tex]7\frac{1}{2}[/tex] grams

Weight of one dose = [tex]\frac{1}{4}[/tex] gram

To Find:

Number of doses in one vial.

Solution:

Let the number of doses in a vial = n

Therefore, weight of 'n' doses = [tex]n\times \frac{1}{4}[/tex]

                                                  = [tex]\frac{n}{4}[/tex] grams

Since, the weight of the n doses is equal to the weight of one vial,

[tex]\frac{n}{4}=7\frac{1}{2}[/tex]

[tex]\frac{n}{4}=\frac{15}{2}[/tex]

[tex]n=\frac{15\times 4}{2}[/tex]

[tex]n=30[/tex] doses

Therefore, 30 doses can be obtained from one vial of medication.

Answer:

Is it anual intrest rate? if so then it would be 1620$ inrest rate  and if it was 6% in 9 years it would be 180$ interest rate

Step-by-step explanation:

Answer:

using the simple interest rate Formula, I = prt.

given 3,000 as the principle,

6% as the rate, and 9 years as the time

I = (3000)(6%)(9)

I = (27000)(6%)

I = (27000)(0.06)

I = 1620$

Present value = I + p

present value = 1620$ + 3000$

present value = 4620$
