The price of 3 chairs and 4 tables is Rs 7540.What is the price of 1 table if the price of a chair is Rs 220.
Given parameters:
Number of chairs = 3
Number of tables = 4
Cost of 3 chairs and 4 tables = Rs 7540
Price of 1 table = Rs220
Unknown:
Price of 1 table = ?
Solution:
Let the cost of 1 table = t
So,
3(220) + 4(t) = 7540
660 + 4t = 7540
4t = 7540 - 660
4t = 6880
t = Rs. 1720
The cost of 1 table is Rs. 1720
3(2-4x)=-30 with justfity steps
Answer:
x = 3
Step-by-step explanation:
3(2 - 4x) = -30
=>6 - 12x = -30
=> 12x = 36
=> x = 3
Find the slope between the two points: (5, 3) and ( 10, 9)
==================================================
Explanation:
Subtract the y coordinates: 9-3 = 6
Subtract the x coordinates in the same order: 10-5 = 5
Divide the differences:
slope = rise/run = (change in y)/(change in x) = 6/5
-------------------
You could also use the slope formula
m = (y2-y1)/(x2-x1)
m = (9-3)/(10-5)
m = 6/5

The number of burritos Phineas ate on Tuesday is the same as the number of burritos Ferb ate on Wednesday. On Tuesday, Phineas ate 16 more than 1/2 the total number of burritos consumed. On Wednesday, Ferb ate 1 less than 3/4 of the total number of burritos consumed. Write an equation to determine the total number of burritos consumed. Hint: let x = # burritos consumed.
Answer:
50 is the answer
Answer:
Phineas eat -16+1/2=x
Ferb ate 1-3/4=x
Step-by-step explanation:
Phineas eats 15.5=x

A city park has a large circular garden with a path around it. The diameter of the garden is 60ft. Jason works for the city park department. He needs to spread plant food all over the garden. What is the area of the park he will cover with plant food?
Answer:
The area is [tex]A = 2827.8 \ ft^2 [/tex] of the park
Step-by-step explanation:
From the question we are told that
The diameter of the garden is d = 60 ft
Generally the radius of the circular garden with a path around it is mathematically represented as
[tex]r = \frac{60}{2}[/tex]
=> [tex]r = 30 \ ft [/tex]
Generally the area of the park he will cover with plant food is mathematically represented as
[tex]A = \pi r^2[/tex]
=> [tex]A = 3.142 * (30 )^2[/tex]
=> [tex]A = 2827.8 \ ft^2 [/tex]

A circle has an area of approximately 78.5 square units. If the center of the circle is at Left-parenthesis 2 comma 4 right-parenthesis. Which of the following points is on the circle? A. Left-parenthesis negative 6 comma 4 right-parenthesis B. Left-parenthesis 2 comma negative 1 right-parenthesis C. Left-parenthesis negative 4 comma negative 4 right-parenthesis D. Left-parenthesis 2 comma negative 9 right-parenthesis
Answer:
The answer is (2, -1)
Step-by-step explanation:
The area of the circle is:
A = r²π
We know
A = 78.5
π = 3.14
78.5 = r² * 3.14
r² = 78.5 : 3.15
r² = 25
r = √25 = 5
The standard form equation of a circle is:
(x - h)² + (y - k)² = r²
We have:
(2, 4)
⇒ h = 2
k = 4
r = 5
(x - h)² + (y - k)² = r²
(x - 2)² + (y - 4)² = 5²
(x - 2)² + (y - 4)² = 25
Now, let's substitute all choices:
(-6, 4):
(-6 - 2)² + (2 - 4)² = 25
(-8)² + (-2)² = 25
64 + 4 = 25
68 = 25
Wrong
(2, -1)
(2 - 2)² + (-1 -4)² = 25
0² + (-5)² = 25
0 + 25 = 25
25 = 25
Right
Hope this helps :p

Tom performs a dilation of ⅓ on a triangle. He then classifies the image and pre-image as being congruent. Is Tom correct? Why or why not? Explain you answer down below.
Answer: Tom is incorrect.
Step-by-step explanation: Congruent is defined as having exactly the same angle measurements and exactly the same side lengths.
In the 1/3 dilation, the angles will remain the same, but all the sides will be shorter, 1/3 the lengths of the original image. The image and pre-image are not congruent. They are similar.

Arabica coffee costs $28 per pound and Robusta coffee
costs $8.75 per pound. How many pounds of Arabica coffee
must you mix with 3 pounds of Robusta coffee to make a
blend that costs $15.50 per pound?
Given parameters:
Cost per pound of Arabica coffee = $28 per pound
Cost of Robusta coffee = $8.75
Given number of pounds of Robusta Coffee = 3 pounds
Total cost of blend per pound = $15.50
Unknown:
Number of pounds of Arabica coffee = ?
Solution:
Let the number of pounds of Arabica coffee = A;
We have to interpret this problem algebraically and solve;
28A + 8.75(3) = 15.5(A + 3)
Now solve the expression above for A;
28A + 26.25 = 15.5A + 46.5
28A - 15.5A = 46.5 - 26.25
12.5A = 20.25
A = 1.62
Number of pounds of Arabica Coffee is 1.62 pound
Answer:
1.62 pound

19
Answer:
x = 19
Step-by-step explanation:
148 and 7x+15 are alternate interior angles and alternate interior angles are equal when the lines are parallel
148 = 7x+15
Subtract 15 from each side
148-15 = 7x+15-15
133 =7x
Divide each side by 7
133/7 =7x/7
19=x

If angle ABD is 90 degrees. Select all of the angles that measure 42 degrees.
Angle 1
Angle 2
Angle 3
Angle 4
Angle 5
Answer:
Measure of angle 2 and angle 4 is 42°.
Step-by-step explanation:
From the figure attached,
m∠ABC = 42°
m(∠ABD) = 90°
m(∠ABD) = m(∠ABC) + m(∠DBC)
90° = 43° + m(∠DBC)
m(∠DBC) = 90 - 43 = 47°
Since ∠ABC ≅ ∠4 [Vertical angles]
m∠ABC = m∠4 = 42°
Since, m∠3 + m∠4 = 90° [Complimentary angles]
m∠3 + 42° = 90°
m∠3 = 90° - 42°
= 48°
Since, ∠5 ≅ ∠3 [Vertical angles]
m∠5 = m∠3 = 48°
m∠3 + m∠2 = 90° [given that m∠2 + m∠3 = 90°]
m∠2 + 48° = 90°
m∠2 = 90 - 48 = 42°
m∠3+ m∠4 = 90° [Since, ∠3 and ∠4 are the complimentary angles]
48° + m∠4 = 90°
m∠4 = 90 - 48 = 42°
Therefore, ∠2 and ∠4 measure 42°.

The equation is The original price is $ . the first people answer this question i give brainliest answer!!! i need this urgent!!! I GIVE 59 POINTS!!!!
Answer:
$32.50
Step-by-step explanation:
Given that :
Sale price of blouse at 30% off = $22.76
Original price of blouse :
Let original price = p
(100 - 30)% of p = $22.76
0.7p = $22.76
p = $22.76 / 0.7
p = $32.51
= $32.50 ( to the nearest hundredth)

Answer:
M=-10
Step-by-step explanation:
after multiplying,we have a(b plus c)
Answer:
The Distributive Property is easy to remember, if you recall that "multiplication distributes over addition". Formally, they write this property as "a(b + c) = ab + ac". In numbers, this means, for example, that 2(3 + 4) = 2×3 + 2×4.
