20.3/3.5*0.58 in a standard form​

Answer:

1800

Step-by-step explanation:

Let y represent the normal selling price

y-y×25/100= 1350

y-y/4= 1350

4y-y/4= 1350

3y/4 = 1350

Cross multiply both sides

3y= 1350×4

3y= 5400

Divide both sides by the coefficient of y whichj is 3

3y/3= 5400/3

y= 1800

Hence the normal selling price is 1800

Answer:

66 pots

Step-by-step explanation:

The height of flower pot is 66 inches

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given:

Measurement of mug = 6 inches

as, the slower pot is 11 times taller than the mug

=11 * 6

=66 inches.

Hence, the height of flower pot is 66 inches

Answer:

Step-by-step explanation:The area of an isosceles triangle is the amount of space enclosed between the sides of the triangle. Besides the general area of the isosceles triangle formula, which is equal to half the product of the base and height of the triangle, different formulas are used to calculate the area of triangles, depending upon their classification based on sides. These different types based on sides are given below:

Equilateral Triangle- A triangle with all sides equal.

Isosceles Triangle- A triangle with any two sides/angles equal.

Scalene Triangle- A triangle with all unequal sides.

Answer:

R = 101

S = 131

Step-by-step explanation:

First, you will want to get your angle T. Since T is on the same line as the angle with 128 degree, you can easily find angel T. They are supplementary angels and form 180.

T=180-128

T=52

You also know that all angles in a triangle equal to 180

Use that to find angle S

180 = R+S+T

180 = 79 + S + 52

180 - 79 - 52 = S

49 = S, exterior S = 180-49 = 131

Exterior R = 180 - 79 = 101

Now add all your exteriors

and

x = -4 + 1

x = -3

Answer:

x = 10

y = -4

Answer:

[tex]f(x) = (0.85)^x[/tex]

Step-by-step explanation:

Exponential amount of decay:

The equation for an amount that decays exponentially has the following format:

[tex]A(x) = A(0)(1 - r)^x[/tex]

In which r is the decay rate, as a decimal.

Decrease by 15%

This means that [tex]r = 0.15[/tex]. So

[tex]f(x) = (1 - r)^x = (1 - 0.15)^x = (0.85)^x[/tex]

So

[tex]f(x) = (0.85)^x[/tex]

Answer:

A

Step-by-step explanation:

The first graph shows a dot on .5 and the recipes calls for half a cup of sugar.

Answer:

Step-by-step explanation:

[tex]f=\frac{1}{2}s[/tex] is the graph of a straight line with a slope of 1/2. This implies that for every cup of sugar, 1/2 a cup of flour is needed. This also implies what the graph looks like in a coordinate plane. Slope is defined as rise over run, or y over x, so if our slope is 1 over 2, from the origin we go up 1 unit and over 2 units along the length of the whole line. The only graph that displays this slope is graph A.

Answer:

A)-19,15,-9,-1,9

Step-by-step explanation:

that's the answer when I compute it

===================================================

Explanation:

If we plug in x = -2, then we get,

y = x^2 + 7x - 9

y = (-2)^2 + 7(-2) - 9

y = 4 - 14 - 9

y = -10 - 9

y = -19

So x = -2 leads to y = -19. The answer is between A and D.

---------

If you repeat those steps for x = -1, then you should get y = -15

Then x = 0 leads to y = -9

x = 1 leads to y = -1

Finally, x = 2 leads to y = 9

The outputs we get are: -19, -15, -9, -1, 9 which is choice A

Choice D is fairly close, but we won't have a second copy of -15, and  we don't have an output of -19.

Answer:

[tex]y+5=-\frac{2}{7} (x-4)[/tex]

Step-by-step explanation:

Hi there!

What we need to know:

1) Determine the slope (m)

[tex]-7x+2y=14[/tex]

First, rearrange this given equation into slope-intercept form ([tex]y=mx+b[/tex]) so we can easily find the slope.

Add 7x to both sides to isolate 2y

[tex]-7x+2y+7x=7x+14\\2y=7x+14[/tex]

Divide both sides by 2 to isolate y

[tex]y=\frac{7}{2} x+7[/tex]

Now, we can identify clearly that the slope of this line is [tex]\frac{7}{2}[/tex]. Because perpendicular lines have slopes that are negative reciprocals, we know that the slope of the line we're currently solving for will have a slope of [tex]-\frac{2}{7}[/tex].

[tex]m=-\frac{2}{7}[/tex]

2) Plug all necessary values into [tex]y-y_1=m(x-x_1)[/tex]

[tex]y-y_1=m(x-x_1)[/tex]

We know that [tex]m=-\frac{2}{7}[/tex] and that the given point is (4,-5). Plug the slope into the equation

[tex]y-y_1=-\frac{2}{7} (x-x_1)[/tex]

Plug the point into the equation

[tex]y-(-5)=-\frac{2}{7} (x-4)\\y+5=-\frac{2}{7} (x-4)[/tex]

I hope this helps!

Answer:

20

Step-by-step explanation:

We can use the Pythagorean theorem since this is a right triangle

a^2+b^2 = c^2  where a and b are the legs and c is the hypotenuse

21^2 + b^2 = 29^2

441+b^2 =841

Subtract 441 from each side

441 +b^2 -441 = 841-441

b^2 = 400

Take the square root of each side

sqrt(b^2) = sqrt(400)

b =20
