Number 3 answered please
Answer:
Step-by-step explanation:
n=3p, d=p-2
10d+5n+p=110 using n and d from above makes this become
10(p-2)+5(3p)+p=110
10p-20+15p+p=110
26p-20=110
26p=130
p=5
n=3p=3(5)=15
d=p-2=5-2=3

Jordyn is weighing the ingredients on a kitchen scale to make bread. The bowl weighs 1 12 pounds. He adds several scoops of flour. the total weight of the bowl and the flour is 2 34 pounds. If each cup weighs 516 pound, how many cups of flour does he add?
Answer:
4 POUNDS OF FLOUR
Step-by-step explanation:
The number of cups of flour he added is 4.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Bowl weight = 1(1/2) pounds
Number of cups of flour weight = x pounds
Now,
Total weight = 2(3/4) pounds
1(1/2) + x = 2(3/4)
x = 11/4 - 3/2
x = (11 - 6)/4
x = 5/4
Now,
Weight of each cup of flour = 5/16 pounds
Now,
The number of cups of flour.
= 5/4 ÷ 5/16
= (5 x 16) / (4 x 5)
= 4
Thus,
The number of cups of flour is 4.

Answer:
y=1/4x+250
Step-by-step explanation:
Answer:
y = 12.5x + 250
Step-by-step explanation:
(4,300) , (8,350)
m = 350 - 300 / 8 - 4 = 25/2 = 12.5
y - 300 = 12.5(x - 4)
y - 300 = 12.5x - 50

Why did the 30-60-90 triangle marry the 45-45-90 triangle
Answer: because they were right for each other.
Step-by-step explanation:
The cause due to which the triangles 30-60-90 married the triangle 45-45-90 would be:
They were right for each other.
Sum Property of TriangleThe sum of property of triangle states that the three angles of triangle give the sum of 180°.
Given that,
Two sets of triangles having the measures:
First set = 30°-60°-90°
Second set = 45°-45°-90°
The first set marries the other as they both are right i.e. 90° to one another and give an equal sum of 180°.
Thus, the above answer is correct.

39°
27
Answer:
33.3
Step-by-step explanation:
Reference angle = 39°
Opposite = 27
Adjacent = x
Apply TOA. Thus:
Tan 39 = Opp/Adj
Tan 39 = 27/x
x * Tan 39 = 27
x = 27/Tan 39
x = 33.3422232 ≈ 33.3 (nearest tenth)

Answer:
[tex]\Huge\boxed{240ft^2}[/tex]
Step-by-step explanation:
Hello There!
The figure shown is a trapezoid with the following dimensions
base 1 = 12ft
base 2 = 20 ft
height = 15 ft
Given these dimensions we need to find the area
We can do this by using the area of a trapezoid formula
[tex]A=\frac{a+b}{2} h[/tex]
where a and b = bases and h = height
Knowing the dimensions all we have to do is plug in the values
[tex]A=\frac{12+20}{2} 15\\12+20=32\\\frac{32}{2} =16\\16*15=240\\A=240ft^2[/tex]
So we can conclude that the area of the floor that needs to be replaced with tile is 240 ft²

Step-by-step explanation:
A shopkeeper marks the price of an article
30% above its cost price and gives a customer discount of
15%. A customer bought that article including 13% VAT at
Rs. 1872.975. Find the marked price of the article and the
gain of shopkeeper
Answer:
The gain percent made by shopkeeper is 10.5%.
Step-by-step explanation:
Given:
Price at which goods are marked = 30%
Discount on the marked price = 15%
To Find:
Gain percentage of the shopkeeper
Solution:
Let the cost price of the product be = 100
Therefore,
MP = 30 + 100 = 130
Since discount is 15%. thus -
Discount = 15/100 x 130
= 19.5
Selling price = MP - Discount
SP = 130 - 19.5
= 110.5
Profit = SP - CP
= 110.5 - 100
= 10.5
Calculating the gain%
Gain% = 10.5/100 x 100
= 10.5
Answer: The gain percent made by shopkeeper is 10.5%.
