We have,

The concept used to solve the division problem 4/5 divided by 6 is the idea of dividing a fraction by a whole number.

To divide a fraction by a whole number, we can interpret it as finding a fraction of a fraction.

In this case, we want to find 4/5 divided by 6, which can be understood as dividing the fraction 4/5 into 6 equal parts.

To use a model to divide 4/5 by 6, we can represent 4/5 as a fraction bar and divide it into 6 equal parts.

If we divide the fraction 4/5 into 6 equal parts, each part would represent 1/6 of the original fraction.

Therefore,

D. L = (12u - 15)m; W = (u + 1)m


plsss answerre huhu helppp​

Answers

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

How many 1/4 gram doses can be obtained from a 7 1/2 gram vial of medication?

Answers

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.

What is the radius of the circle in the xy-plane that
has center (1,5) and contains the point (4,9)?

Answers

[tex] \huge \qquad \sf \underline{\boxed{ {☘ \sf Sσlutiσn}}}[/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{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,

h = x - coordinate of centre

k = y - coordinate of centre

r = radius of the circle

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

How to determine the radius of the circle?

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

Finding the original price given the sale price and percent...
At a sale this week, a sofa is being sold for $234. This is a 28% discount from the original price.
What is the original price

Answers

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,

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0.

In this problem, the function is given by:

y = 2x + 30.

Hence, the y-intercept is of b = 30, that is, when x = 0, y = 30, and the slope of m = 2 means that when x increases by 1, y increases by 2, hence table B is the answer for this question.

Equation of a Straight Line

1.1 Solve y+2x-5 = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line y+2x-5 = 0 and calculate its properties

Graph of a Straight Line :

Calculate the Y-Intercept :

Notice that when x = 0 the value of y is 5/1 so this line "cuts" the y axis at y= 5.00000

y-intercept = 5/1 = 5.00000

Calculate the X-Intercept :

When y = 0 the value of x is 5/2 Our line therefore "cuts" the x axis at x= 2.50000

x-intercept = 5/2 = 2.50000

Calculate the Slope :

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 5.000 and for x=2.000, the value of y is 1.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 1.000 - 5.000 = -4.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

Slope = -4.000/2.000 = -2.000

Geometric figure: Straight Line

Slope = -4.000/2.000 = -2.000

x-intercept = 5/2 = 2.50000

y-intercept = 5/1 = 5.00000
