Answer:
5600 square feets
Step-by-step explanation:
Let [tex]l, b[/tex] denote length and breadth of the rectangular shaped bedroom.
The total distance around Regina rectangular shaped bedroom is 300 feet.
[tex]2(l+b)=300\\l+b=150[/tex]
The length of the room is 80 feet.
Put [tex]l=80[/tex]
[tex]80+b=150[/tex]
[tex]b=150-80=70[/tex] feets
Area of the rectangular shaped bedroom [tex]=lb=80(70)=5600[/tex] square feets.

What is the 13th square number?
Answer:
169
Step-by-step explanation:
hope this will help you
Which equation has a solution of X=
13?
O
X+ 3 = 10
O x-10=3
* = 26
Ox+12= 1
Answer:
x-10=3
x+10-10=3+10
x=13
Answer:
x - 10 = 3
Step-by-step explanation:
x - 10 = 3
Add 10 to both sides
x - 10 + 10 = 3 + 10
x = 13
Find the lines slope and a point on the line of y-1=-3/2(x+3)
Answer:
y= −3 /2 x+ −7 /2
slope= -3/2
Step-by-step explanation:
y−1= −3 /2 (x+3)
y= −3 /2 x+ −7 /2
according to y=mx+b slope intercept form
-3/2 is the slope

How many years, to the nearest tenth, will be needed for $5000 to increase to $18000 at 3.0% annual interest compounded
Complete question :
How many years, to the nearest tenth, will be needed for $5000 to increase to $18000 at 3.0% annual interest compounded monthly
Answer:
Step-by-step explanation:
Initial amount (P) = 5000
Final amount (A) = 18000
Interest rate (r) = 3% = 0.03 compounded monthly
A = P(1 + r/n)^nt
n = number of compounding timea per period
18000 = 5000(1 + 0.03 / 12)^12t
18000 / 5000 = (1 + 0.0025)^12t
3.6 = (1 + 0.0025)^12t
3.6 = 1.0025^12t
Take the In of both sides
1.2809338 = 1.03t
t = 1.2809338 / 1.03

Explain how to use multiplication to divide a whole number by a fraction.
Answer:
You are multiplying the whole number with the reciprocal of the fraction.
Step-by-step explanation:
To divide a whole number by fraction.
You are taking X which is a whole number over the fraction.
its the same as taking x and multiplying it by the reciprocal of the fraction
So if you have 5 divided by 1/2, it's the same as saying 5 times 2/1.

A rectangular pyramid has a height of 8 meters. The base is 7 meters in length and 15 meters in width two different triangular cross sections are formed through the vertex and perpendicular to the base and to each other. What is the difference in the areas of the cross section? help- please-
Answer:
The difference in the areas of the cross section is 32 m²
Step-by-step explanation:
The given parameters are;
The height of the rectangular pyramid = 8 meters
The length of the base of the pyramid = 7 meters
The width of the base of the pyramid = 15 meters
Whereby triangular cross sections are formed through the vertex and perpendicular to the base, and to each other, we have;
The sides of the two triangles consists of the following;
1) Two slant height of the pyramid each
2) The two perpendicular lines joining the midpoints of the opposite sides of the base of the pyramid with length equal to the length of the adjacent side to the sides from which they are drawn which are 15 meters and 7 meters
3) The two lines and the corresponding slant height form triangles cross section which are perpendicular to each other.
the slant height, [tex]h_l[/tex], is given as follows;
[tex]h_l[/tex] = √(8² + (15/2)²) ≈ 10.966
For the triangular cross section with base = 15 m
The area of the cross section = 1/2 × Base₁₅ × Height = 1/2 × 15 m × 8 m = 60 m²
For the triangular cross section with base = 7 m
The area of the cross section = 1/2 × Base₇ × Height = 1/2 × 7 m × 8 m = 28 m²
The difference in the areas of the cross section = 60 m² - 28 m² = 32 m².

A garden is in the shape of a right triangle. The base of the triangle is 12m, and the garden covers an area of 30m squared. What length of fence is needed to surround the garden?
Answer:
= 30m
Step-by-step explanation:
to find the length of the fence, find the perimeter of the triangle.
that is b + h + hyp assuming b is the base, h is height and hyp is hypotenuse.
we have the base; height and hypotenuse are not given.
to get the height,
area(A) = 30m2
base(B) = 12m
height(H) = ?
A = 0.5 x B x H
30m2 = 0.5 x 12m x H
30m2 = 6m x L
H = 30m2 / 6m
H = 5m
to get the hypotenuse,
we have to complete the Pythagorean family the base ,12, and height, 5. is in.
formula = a2 + b2 = c2, c is the hypotenuse, a and b can be interchanged either way with base and height.
= (12 x 12) + ( 5 x 5) = c2
= 144 + 25 = c2
= 169 = c2
c2 = 169
c = 13
perimeter = b + h + hyp
= 5 +12 + 13
= 30m

An electric heater uses 7 1/2 units of electricity in 3 hours. How many units does it use in 5 hours?
Answer:
12.5 units or 12 1/2 units
Step-by-step explanation:
From the question, it uses 7.5 units in 3 hours.
In one hour it will use; 7.5/3 = 2.5 units
If 2.5 units is used in 1 hour
In 5 hours; 5 × 2.5 units will be used. This gives us 12.5 units or 12 1/2 units.
Gary is making a model of the garage he is going to build in his backyard. The actual length of the garage is 75 feet. The model's length is 15 inches. Complete the scale: 1 in. = ?.
Answer:
The scale: 1 inches = 5 feet
Step-by-step explanation:
Given:
Actual length of backyard = 75 ft
Model's length = 15 inches
Complete;
The scale: 1 inches = ?
Computation:
The scale = Actual length of backyard / Model's length
The scale = 75 / 15
The scale = 5 ft
So,
The scale: 1 inches = 5 feet

Write 2 cents using the dollar symbol (without spaces)
Answer:
$0.02
Step-by-step explanation:
This is the correct way to do 2 cents. Since two is not in the tenths place, and is not yet a dollar, the correct answer is $0.02.
Hope this helps! :D
The representation of 2 cents in dollar sign will be $0.02.
What is unit conversion?To convert any unit into another is called a unit conversion.
In order to convert units, we need to care about their dimensions their dimension should not be changed.
It is known that,
$1 = 100 cents
Divide both sides by 100
$1/100 = 1 cents
Multiply by 2 on both sides,
$(1/100)2 = 2 cents
$0.02 = 2 cents
Hence "The representation of 2 cents in dollar sign will be $0.02".

Which expression can be modeled using the number line?
Answer:
Expression that can be modeled using the number line is 7 over 10 divided by 1 over 10
Step-by-step explanation:
Arrow starts from 0 then it goes to 1/10 then to 2/10 then to 3/10 then to 4/10 then to 5/10 then to 6/10 then to 7/10.
Which implies 7/10 is divided into 7 equal parts of the equal length of 1/10 units.
