Ms. Pendleton’s bedroom is a shape of a rectangle. The width of the room is 16 feet and length is four more feet than the width.

QveST [7]

Answer:

The answer to your question is Perimeter = 64 ft

Step-by-step explanation:

Data

width = 16 ft

length = width + 4 ft

Perimeter = ?

Process

1.- Calculate the length

Length = 14 + 4 = 18 ft

2.- Look for the formula of the perimeter

Perimeter = 2(length) + 2(width)

3.- Substitution

Perimeter = 2(18) + 2(14)

4.- Simplification

Perimeter = 36 + 28

5.- Result

Perimeter = 64 ft

What's the slope of (6, 5) and (3, 7.5) ?

noname [10]

Answer:

The slope of (6, 5) and (3, 7.5) is 5/-6.

As a decimal: (-0.83333333333...)

Step-by-step explanation:

Formula for slope:

$m=\frac{y^2-y^1}{x^2-x^1}$

('m' means slope.)

$(x^1,y^1) =$ coordinates of the first coordinate point

$(x^2,y^2)=$ coordinates of the second coordinate point.

--------------------------

Coordinates:

$(6,5)(3,7.5)$

-------------------------

Now, I will simply plug the numbers into the formula.

$m=\frac{7.5-5}{3-6} =\frac{2.5}{-3} =5/-6$

As a decimal: (-0.83333333333...)

What is the minimum point on a graph of f(x) = (x - 1)² - 3?

mariarad [96]

Answer:

(1, -3)

First option

Step-by-step explanation:

The minimum point on the graph is also the <u>vertex</u>.

The quadratic function equation is given in <u>vertex form</u>, which is $f(x) = a(x - h)^{2} + k$

Using this equation, the vertex is (-h, k).

Whatever number you see for "h", find its opposite negative/positive. That will be the x-coordinate of the vertex. The y-coordinate for the vertex is the same as "k", keeping the negative and positive.

In f(x) = (x - 1)² - 3 using (-h, k) is:

h = -1 => -h = 1

k = -3

Therefore the vertex is (1, -3).

Linda has d dollars in an account that pays 1.4% interest, compounded weekly. She withdraws w dollars. Express her first week’s

Fittoniya [83]

Answer:

If the 1.4% rate of interest is the weekly rate of interest, Then, total first week interest = 1.4(d - w)/100 = 0.014(d - w)

But if the 1.4% rate of interest is a yearly rate of interest compounded weekly, then her total first week interest = 7(d - w)/2600 = 0.00269 (d - w)

Step-by-step explanation:

The interest, I = PRT

P = initial amount of dollars in account = (deposit - withdrawal) = (d - w)

R = rate of interest = 1.4% = 0.014/week

T = time = 1 week

If the 1.4% rate of interest is the weekly rate of interest

I = PRT = (d - w) × 0.014 × 1 = 0.014(d - w)

But if the 1.4% rate of interest is a yearly rate if interest compounded weekly,

P = initial amount of dollars in account = (deposit - withdrawal) = (d - w)

R = rate of interest = 1.4% = 0.014/year

T = time = 1 week = (1/52) years

I = PRT = (d - w) × 0.014 × (1/52) = 7(d - w)/2600 = 0.00269 (d - w)

Hope this Helps!!!

A square that is 5yd on a side is placed inside a rectangle that has a width of 11yd and a length of 17 yd. What is the area of

Anit [1.1K]

Answer: 162 sq. yds.

Step-by-step explanation:

Given : A square that is 5yd on a side is placed inside a rectangle that has a width of 11yd and a length of 17 yd.

Then , Area of rectangle = length x width

= 11 yd x 17 yd = 187 sq. yds.

Area of square = (side)²

= (5 yd)² = 25 sq. yds.

Now , the area of the region inside the rectangle that surrounds the square will be Area of rectangle - Area of square

= 187 sq. yds.- 25 sq. yds.

=162 sq. yds.

Hence, the area of the region inside the rectangle that surrounds the square is 162 sq. yds. .
