Answer:
Area of the remaining patio = 2.67 square yards
Step-by-step explanation:
Width of the remaining area of the patio = [tex]\frac{2}{3}[/tex] yards
Length of the remaining area of the patio = 4 yards
Since, area of the remaining area of the rectangular patio
= Length × Width
= [tex]\frac{2}{3}\times 4[/tex]
= [tex]\frac{8}{3}[/tex]
= 2.67 square yards
Therefore, area of the remaining area of the patio = 2.67 square yards
2a+3b=5
b=a-5 help please
Answer:
2a + 3b = 5
b = a - 5
Step-by-step explanation:
2a + 3b = 5
b = a - 5
You can write this another way:
2a + 3(a-5) = 5 ( I added the second formula in the first one )
Now you gotta factor out:
2a + 3a - 15 = 5
Here im gonna do plus 15
2a + 3a = 20 ==> 5a = 20
Now if you divide by 5, you get: a = 4
Now you can fill in the second formula again
b = a - 5 (ill fill this in now)
b = 4 - 5 = -1
So, this makes:
a = 4 , b = -1
Answer:
a = -2
b = -7
Step-by-step explanation:
the best method to solving this system of equations would be substitution since you are given an expression that equals one of the variables you're solving for (which is b = a - 5)
to begin, plug in a - 5 for b in the equation 2a + 3b = 5.
2a + 3b = 5 ⇒ 2a + 3(a - 5) = 5
the next step is to distribute 3 to a - 5. start with distributing 3 to a, which is just multiplying 3 · a. after that, you're left with a minus sign and 5, so that sign gets attached to the 5 and makes it a -5. distribute 3 to -5, which is just multiplying 3 · -5.
2a + 3(a - 5) = 5 ⇒ 2a + 3a - 15 = 5
since you have two terms with the variable a on one side of the equation (2a and 3a), combine the two like terms.
2a + 3a - 15 = 5 ⇒ 5a - 15 = 5
add 15 to both sides of the equation. on the left side, -15 and 15 cancel each other out because -15 + 15 = 0, leaving you with only 5a. on the right side of the equation, you have 5 - 15, which equals -10.
now your equation is 5a = -10.
divide both sides of the equation by 5. on the left side of the equation, you have 5a/5, which equals 1a, or a. on the right side, you have -10/5, which equals -2.
therefore a = -2.
now plug in -2 for a in b = a - 5 in order to solve for b!
b = a - 5 ⇒ b = -2 - 5
subtract -2 - 5.
b = -2 - 5 ⇒ b = -7
therefore b = -7.
your solutions are a = -2 and b = -7 :) i hope this helps! have a great day <3
Which of the following pairs show(s) two congruent triangles?
Answer:
B only
Step-by-step explanation:
In A and in C, only the angles of one triangle are congruent to the corresponding angles of the other triangle. That proves similar triangles but not necessarily congruent triangles.
Definition of congruent triangles:
Two triangle are congruent if all angles of one triangle are congruent to all corresponding angles of the other triangle and all sides of one triangle are congruent to all corresponding sides of the other triangle.
That happens only with the triangles in B.
Answer: B only
Out of three pairs, only pair B is an example of congruent triangles because they are exactly the same.
What are congruent triangles?
Two triangles are said to be congruent if they are exactly the same i.e. corresponding sides, as well as corresponding angles, are equal.
A)Triangles shown are similar triangles because the corresponding sides are not equal. In fact, they are in proportion.
B)Triangles shown are congruent because corresponding sides, as well as corresponding angles, are equal.
C)Triangles shown are similar triangles because the corresponding sides are not equal. In fact, they are in proportion.
Hence, out of three pairs, only pair B is an example of congruent triangles because they are exactly the same.

Roberto earns $6.50 per hour. He worked 32 hours at the regular rate, 8 hours at a time and a half, and 8 at double time. How much did he earn?
Answer $390
Step-by-step explanation:
Answer:
$390
Step-by-step explanation:
First Roberto works 32 hours at 6.50 per hour. At that time, he earn 32*6.5 = $208. Then he works 8 hours at a time and a half. This means that his pay rate is 50% more, or 6.5*1.5 = $9.75 per hour. Since he worked 8 hours at this pay rate, he earns 8*9.75 = $78. And then he works 8 hours double time. This means his pay rate was doubled during that duration. 6.5*2 = 13, 13*8 = $104.
Total: 208 + 78 + 104 = $390

The population of a town has been growing, following the equation P=400t+3000, where t is years after 2010. The number of restaurants in the town has been growing according to the equation R=6t+35.
Complete an equation for the number of restaurants per capita (per person)
Restaurants per capita: ______
How many restaurants per capita does this model predict for the year 2016?_______
Please also explain it to me, only if you can! Thank you!
Step-by-step explanation:
t is time since 2010. so,
the population prediction for 2016 is :
p= 400 ( 2016-2010)+3000
p= 400 (6) + 3000=5400
the number of restaurant prediction for 2016 is.
R=6(2016-2010)+35
R=6 (6)+35=71
so, per capita (per person) there would be:
71 restaurant for 5400.
people that is :71/5400 or 0.0131 restaurant per person.
per restaurant there would be,5400/71 or 76.056 per restaurant.
population corresponding to time (t).
=( R/ P) = (6t + 35). / 400t + 3000, where t= 2016-2010= 6 years
= 71/5400
= 0.0131
Restaurant per capita
R/P = (6t+35) / (400t + 300)
t= 2016-2010 =16
R/P = (6.16+35) /(400.16+3000)
= 131 (6400+3000)
=85/9400
=0.009042

Find the area of rectangle ABCD
Answers:
A. 20
B. 10 square root 2 + square root of 82
C. 24
D. 12
9514 1404 393
Answer:
D. 12
Step-by-step explanation:
There are a number of ways to find the area of this rectangle. Perhaps the most straightforward is to find the lengths of the sides and multiply those. The distance formula is useful.
d = √((x2 -x1)^2 +(y2 -y1)^2)
Using the two upper-left points, we find the length of that side to be ...
d = √((3 -0)^2 +(3 -0)^2) = √(9 +9) = √18 = 3√2
Similarly, the length of the lower-left side is ...
d = √((-2 -0)^2 +(-2 -0)^2) = √(4+4) = √8 = 2√2
Then the area of the rectangle is ...
A = LW
A = (3√2)(2√2) = 3·2·(√2)^2 = 3·2·2 = 12
The area of rectangle ABCD is 12.
_____
Other methods include subtracting the area of the corner triangles from the area of the bounding square:
5^2 -2(1/2)(3·3) -2(1/2)(2·2) = 25 -9 -4 = 12
