The length and width or a rectangular courtyard is 40 feet and 30 feet, respectively. In order to make the courtyard larger, an additional 15 feet is being added to the width
Answer:
The new area is 1800feet^2
Step-by-step explanation:
Step one:
Given data
The length and width or a rectangular courtyard is 40 feet and 30 feet
we can calculate the area of the courtyard as
Area= 40*30
Area= 1200 feet^2
when the extra 15 feet is added to the width
the new width is= 30+15= 45feet
The new area is
Area= 40*45
Area= 1800 feet^2
in all the area will increase by 1800-1200= 600feet

Answer:
Step-by-step explanation:
4/3(6y+21)-17=43
move all terms to the left:
4/3(6y+21)-17-(43)=0
Domain of the equation: 3(6y+21)!=0
y∈R

What is the largest number of combination bags that Diego can make with no left over? Explain how you know this is the largest possible number of bags?
This question is incomplete
Complete Question
Diego is preparing brownies and cookies for a bake sale. He would like to make equal-size bags for selling all of the 48 brownies and 64 cookies that he has. What is the largest number of combination bags that Diego can make with no left over? Explain how you know this is the largest possible number of bags?
Answer:
16 bags.
Step-by-step explanation:
From the question, we have:
48 brownies and 64 cookies that he has
Hence, we solve this question using Greatest common factor method.
The first step would be to find the factors of 48 and 64. We would then pick the Greatest (largest factor) common to both.
The factors of 48 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48
The factors of 64 are: 1, 2, 4, 8, 16, 32, 64
Then the greatest common factor is 16.
Therefore, the largest number of combination bags that Diego can make with no left over is 16 bags

Daniel began filling an empty swimming pool at 8:30 a.M. After 5 hours, the pool contained 230 gallons of water. If the water input contained at a constant rate, how many more hours are needed to completely fill the 920-gallon pooo?
It will take 20 hours to fill the 920-gallon water in the pool if Daniel began filling an empty swimming pool at 8:30 a.M. After 5 hours, the pool contained 230 gallons of water.
What is a fraction?Fraction number consists of two parts one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
We have:
After 5 hours the pool filled with 230 gallons
Let's suppose that after x hours the pool will fill with 920 gallons
After x hours the pool filled with 920 gallons.
As the water input contained at a constant rate
So the value of x can be evaluated:
[tex]\rm x = \frac{920\times5}{230}[/tex]
x = 20 hours
Thus, it will take 20 hours to fill the 920-gallon water in the pool if Daniel began filling an empty swimming pool at 8:30 a.M. After 5 hours, the pool contained 230 gallons of water.

Answer:
a) 720°
b) 98
Step-by-step explanation:
a) The sum of interior angles of an n-gon is (n-2)×180°. For n=6, the sum is ...
(6 -2)×180° = 4×180° = 720°
__
b) The sum of the marked angles is 622°, so the value of x is ...
x = 720 -622
x = 98
Write the coordinates of the vertices after a rotation 180° counterclockwise around the origin

Answer:
5($2.50)+3($1.50)=17
Step-by-step explanation:
you you just need to put up quantity by side of the bar pound it goes in the brackets that will give you the answer when you multiply that or something fruits value.
[tex]\boldsymbol{\$\,17}[/tex]
Algebraic ExpressionAn algebraic expression is one that is composed of integer constants, variables, and algebraic operations.A mathematical operation is a mathematical action. A mathematical operation includes addition, subtraction, multiplication, division, and calculating the root.Cost of [tex]5[/tex] pounds of apples at [tex]\$2.50[/tex] per pound [tex]=\$\,(5\times 2.50)[/tex]
Cost of [tex]3[/tex] pounds of grapes at [tex]$1.50[/tex] per pound [tex]=\$\,(3\times 1.50)[/tex]
Therefore,
Total cost of the fruit [tex]=\$\,(5\times 2.50)+\$\,(3\times 1.50)[/tex]

Decrease £313 by 62%
Give your answer rounded to 2 DP.
Answer:
194.06
Step-by-step explanation:
£313 decreased by 62% is £118.94
In order to determine the answer, the first step to take is to determine the value of 62% of £313.
Value of 62% = 62% x £313
0.62 x £313 = £194.06
The second step is to subtract the value of 62% of £313 from £313
£313 - £194.06 = £118.94
In order to decrease £313 by 62%, the first step is to determine the value of 62% of £313 and then subtract the value gotten from the previous step from £313.

[tex]m\angle 1=95^{\circ}[/tex]
Step-by-step explanation:
If we drew an auxiliary line parallel to line [tex]p[/tex] and line [tex]q[/tex] that intersects the vertex of [tex]\angle 1[/tex], we would form three angles, one of them being
The largest of these angles corresponds with the angle marked as [tex]148^{\circ}[/tex].
The angle on the bottom right corresponds with the angle next to the one marked as [tex]63^{\circ}[/tex]. Therefore, its measure is [tex]180-63=117^{\circ}[/tex].
Since there are [tex]360^{\circ}[/tex] in a circle, we can now write the following equation:

The way SkiffMacKinaw did this problem is the way it should be done. There is another way of doing it by extending both arms of <1 until they intersect p and q and solve the triangle hanging from p.
You then find the the angles of the triangle. The vertex angle is the supplement to <1.

1) A tv has a sale price of $450 and has a sales tax of 6% Find the total price.
Sales tax:
Total price:
Answer:
Sales tax : $27
Total price : $477
Step-by-step explanation:
Given that:
Sale price of tv = $450
Sales tax = 6%
Amount of sales tax = [tex]\frac{6}{100}*450[/tex]
Amount of sales tax = 0.06 * 450
Amount of sales tax = $27
Total price = Sale price + Sales tax
Total price = 450 + 27 = $477
Hence,
Sales tax : $27
Total price : $477
