The perimeter of a rectangular poster is 14 feet and the length is 4 feet. Describe how to use the perimeter formula to find the width.This calculator has a tray why the answer is not 3.2

Answers

Answer 1

Explanation

We are told that the perimeter of a rectangular poster is 14 feet and the length is 4 feet.

Perimeter simply means the total sum of all the sides of the rectangle

[tex]\begin{gathered} From\text{ the above} \\ let\text{ the length = y} \\ width\text{ =x} \end{gathered}[/tex]

So, the perimeter is

[tex]x+x+y+y=2x+2y[/tex]

Since the perimeter is 14 then

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

Also, the length is 4 feet

Therefore y = 4, so that

[tex]\begin{gathered} 2x+2(4)=14 \\ 2x+8=14 \\ collecting\text{ like terms} \\ 2x=14-8 \\ 2x=6 \end{gathered}[/tex]

Making x the subject of the formula

[tex]\begin{gathered} x=\frac{6}{2}=3 \\ \\ x=3 \end{gathered}[/tex]

Therefore, the width of the rectangle is 3 feet

The rectangle is

[tex]4+3+4+3=14[/tex]

I need to find the equation of a circle I will include picture

Given,

The center of the circle is (6, -3).

The coordinates of the point, circle is passing through (6,6).

The general equation of the circle is,

[tex](x-h)^2+(y-k)^2=r^2[/tex]

Here, x, y are the coordinates of the point.

h and k are the center of the circle.

r is the radius of the circle.

Substituting the value of h, k , x and y in the equation of circle then,

[tex]\begin{gathered} (6-6)^2+(6-(-3))^2=r^2 \\ 0+9^2=r^2 \\ r=9 \end{gathered}[/tex]

So, the radius of the circle is 9.

Substituting the value of h, k and r in the general equation of circle.

[tex]\begin{gathered} (x-6)^2+(y-(-3))^2=9^2 \\ x^2+36-12x+y^2+9+6y=81 \\ x^2+y^2-12x+6y-36=0 \end{gathered}[/tex]

For her phone service, Mai pays a monthly fee of $19, and she pays an additional $0.04 per minute of use. The least she has been charged in a month is$70.28. What are the possible numbers of minutes she has used her phone in a month?

Answers

We have a phone service fee which can be divided in:

- A fixed fee of $19 per month.

- A variable fee of $0.04 per minute, so that the cost for m minutes is 0.04*m.

We can add the two fees to express the total cost in function of the minutes as:

[tex]C(m)=19+0.04m[/tex]

For a month where the cost is C(m) = 70.28, we can calculate the minutes as:

[tex]\begin{gathered} C(m)=70.28 \\ 19+0.04m=70.28 \\ 0.04m=70.28-19 \\ 0.04m=51.28 \\ m=\frac{51.28}{0.04} \\ m=1282 \end{gathered}[/tex]

Answer: if she pays at least $70.28, she has talked at least m = 1282 minutes per month.

Find the time. Round to the nearest day given the following:Principal: $74,000Rate: 9.5%Interest: $2343.33

Answers

Explanation

Simple Interest is calculated using the following formula:

[tex]I=\text{PRT}[/tex]

where P is the principal ( initial amount)

R is the rate ( in decimal)

T is the time ( in years)

so

Step 1

Let

[tex]\begin{gathered} P=74000 \\ \text{rate}=\text{ 9.5\% =9.5/100= 0.095} \\ T=t\text{ ( unknown)} \\ \text{Interest}=\text{ 2343.33} \end{gathered}[/tex]

now, replace

[tex]\begin{gathered} I=\text{PRT} \\ 2343.33=74000\cdot0.095\cdot t \\ 2343.33=7030t \\ \text{divide both sides by 7030} \\ \frac{2343.33}{7030}=\frac{7030t}{7030} \\ 0.3333=t\text{ } \end{gathered}[/tex]

so, the time is 0.333 years

Step 2

convert 0.333 years into days

[tex]1\text{ year }\Rightarrow365\text{ days}[/tex]

so

[tex]\begin{gathered} 0.333years(\frac{365}{1\text{ year}})=121.66 \\ \text{rounded} \\ 122\text{ days} \end{gathered}[/tex]

therefore, the answer is

Number 14. Need help finding the area of the shaded area. Forgot how to solve it. Please help.

Substituting with b = 16 cm (given that the radius of the circle is 8 cm, then the length of the square's side is 2x8 = 16 cm):

In this case, Abby baked 2-dozen brownies, she took 1 dozen to her scout meeting and her family ate 8, and she put the rest in a container in the refrigerator.

Therefore, the remaining amount will be:

= 2 dozens - 1. dozen - 8

We will have the following:

First:

Since we have that sides a & c have the same length by theorem angles A & C are equal, so the following is true:

[tex]A+B+C=180\Rightarrow2A+B=180[/tex][tex]\Rightarrow2A=180-25\Rightarrow A=77.5[/tex]

so, angles A & C have a measure of 77.5°.

*Second: We determine the measurement f the segment b, that is:

[tex]\frac{b}{\sin(25)}=\frac{25}{\sin(77.5)}\Rightarrow b=\frac{25\sin (25)}{\sin (77.5)}[/tex][tex]\Rightarrow b=10.8219807\Rightarrow b\approx10.8[/tex]

A = 77.5°

b = 10.8

C = 77.5°

What is the solution set of x² + 5x - 5 = 0?

Answers

The solution of x² + 5x - 5 = 0 is  :

x = 0.854 and -5.854 .

Solution:

Here given equation,

x2 + 5x - 5 = 0

To solve the given equation use quadratic formula,

Using the quadratic formula,

x = [-b ± [tex]\sqrt{b2 - 4ac}[/tex] ] /2a

Here,

a = 1, b = 5 and c = -5

By substituting,

x = [-5 ± [tex]\sqrt{52 - 4(1)(-5)}[/tex] ] /2(1)

= [-5 ± √[tex]\sqrt{25 + 20}[/tex]] /2

= [-5 ± √45] /2

= [-5 ± 6.708] /2

So,

x = (-5 - 6.708)/2

= -11.708/2

= -5.854

= (-5 + 6.708)/2

= 1.708/2

Answer:

[tex]\Delta CAT\text{ is an ISOSCELES triangle}[/tex]

Explanation:

To properly classify the traingle, we need to get the length of the sides

To get the length of the sides, we need to get the distance between each two points using the distance between two points formula

Mathematically,we have the formula as:

[tex]D\text{ = }\sqrt[]{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Where (x1,y1) refers to the coordiantes of the first point while (x2,y2) refers to the coordinates of the second point

let us get the coordinates of the individual points as seen from the plot shown

C (1,8)

A (5,10)

T (7,6)

So, let us find the distance between each two points

For AC, we have:

[tex]D\text{ = }\sqrt[]{(5-1)^2+(10-8)^2}\text{ = }\sqrt[]{20}[/tex]

For AT, we have:

[tex]D=\sqrt[]{(7-5)^2+(6-10)^2\text{ }}\text{ = }\sqrt[]{20}[/tex]

Lastly, for CT, we have:

[tex]D\text{ = }\sqrt[]{(7-1)^2+(6-8)^2\text{ }}\text{ = }\sqrt[]{40}[/tex]

From our calculations, we can see that AC = AT

If we have a triangle which has two of its sides equal in length (the angle facing these sides would be same too), we call this an isosceles triangle

If 1 yard of blue fabric is used: b=1

[tex]\begin{gathered} 6\frac{2}{3}\times1=5\frac{1}{3}g \\ \frac{20}{3}=\frac{16}{3}g \\ \text{ Multiply both sides by }\frac{3}{16} \\ \frac{3}{16}\times\frac{20}{3}=\frac{16}{3}\times\frac{3}{16}g \\ g=\frac{20}{16} \\ g=1\frac{1}{4}\text{ yards} \end{gathered}[/tex]

If 1 yard of blue fabric is used, then 1 1/4 yards of green fabric will be used.

hello

the question here is a given quadratic equation and we're required to use quadratic formula to solve it.

[tex]2x^2-3x-4=0[/tex]

now, to solve this, let's bring out quadratic formula first

[tex]x=-b\pm\frac{\sqrt[]{b^2-4ac}}{2a}[/tex]

now from our equation given, we can easily identify a, b and c.

[tex]\begin{gathered} 2x^2-3x-4=0 \\ a=2 \\ b=-3 \\ c=-4 \end{gathered}[/tex]

next we plug in the variables into the equation and solve
