Step-by-step explanation:
Force (F) = 450 N
Pressure (P) = 15 N/m² or 15 pa
Area (A) = ?
We know the force acting normally per unit area is pressure so,
P = F / A
15 = 450 / A
A = 450 / 15
A = 30 m²
The area to which the force has been applied is 30 m².
Hope it will help :)❤

It was estimated that 825 people would attend the soccer game , but 817 people actually attended what is the percent error , to the nearest percent , of the estimate
Answer:
1
Step-by-step explanation:
First we will divide those who attended with the estimated number 0f those who should attend.
= 817/825
= 0.9903
We will then multiply the above result with 100
= 100 × 0.9903
= 99.0303
The next step is to deduct the above result from 100

Which property is shown by 9+8=8=9?
1: Distributive Property
2: Commutative Property of Addition
3: Associative Property of Addition
Answer:
A. Commutative Property of Addition
Step-by-step explanation:
Given equation,
9 + 8 = 8 + 9
If a and b are any real numbers,
By the commutative Property of Addition
a + b = b + a
By the identity Property of Addition
a + 0 = a
By the distributive Property,
a(b+c) = ab + ac
By the associative property of addition,
a + (b + c ) = (a + b) + c
Hence, OPTION A is correct.
Answer:
Commutative Property of Addition
Step-by-step explanation:
I assume you mean 9+8=8+9
In that case it is the Commutative Property of Addition.
That means you can switch the numbers around and it will stay the same value.
The angle of depression from a helicopter to its landing space is 56°. If the helicopter is flying at 1000 ft, find the distance from the helicopter to the landing space
Answer:
[tex]1206.22\ \text{ft}[/tex]
Step-by-step explanation:
The height at which the helicopter is 1000 ft
Angle of depression is [tex]56^{\circ}[/tex]
[tex]\theta=90-56=34^{\circ}[/tex]
We have the relation
[tex]\cos\theta=\dfrac{\text{Adjacent side}}{\text{Hypotenuse}}\\\Rightarrow \cos34^{\circ}=\dfrac{1000}{x}\\\Rightarrow x=\dfrac{1000}{\cos 34^{\circ}}\\\Rightarrow x=1206.22\ \text{ft}[/tex]
The distance of the helicopter to the landing space is [tex]1206.22\ \text{ft}[/tex].

Answer: 7.3
Step-by-step explanation:
Do the parentheses first!
4-7= -3
Then, multiply -3 by 2
-3×2= -6
Next,
-6-6.7= -12.7
Then, add -12.7 to 20
-12.7+20=7.3
Your answer is 7.3

Multiply the bottom equation by 3 then subtract the bottom equation from the top equation
Multiply the bottom equation by -3/2 then add the equations.
Multiply the top equation by-3. then add the equations
Answer:
Multiply the bottom equation by -3/2 then add the equations.
Multiply the top equation by-3. then add the equations
Step-by-step explanation:
Given the simultaneous equation
2x- 6y=6 ... 1
6x - 4y = 2 ... 2
To eliminate a variable, we have to make the coefficient of one of the variable to be the same.
Multiply equastion 1 by -3
-6x+18y= -18
6x - 4y = 2
Add the result:
-6x + 6x + 18y-4y = -18+2
18y-4y = -18+2
14y = -18
y = -9/7
Another way is to Multiply the bottom equation by -3/2 then add the equations.
Multiplying equation 2 by -3/2 will give;
6x(-3/2) - 4y(-3/2) = 2(-3/2)
-9x + 6y = -3
Add to equation 1;
2x- 6y=6
-9x + 2x + 0 = -3+6
-7x = 3
x = -3/7
Hence the correct two options are;
Multiply the bottom equation by -3/2 then add the equations.
Multiply the top equation by-3. then add the equations
Expand and simplify (x + 3)(x + 5)

Riya wants curtains in her room. These are the lengths of curtains in metres. 1.0 m, 1.25 m, 1.5 m The lengths follow a pattern. Riya wants the next length up from 1.5 m. What length of curtains will Riya buy?
Answer:
1.75
Step-by-step explanation:
Since the curtains are going up in .25. We need to add .25 to 1.5.
1.5 + .25 = 1.75
The length of curtains will Riya buy is 1.75 m.
What is sequence?A sequence is an arrangement of numbers in a specific order. A series, on the other hand, is defined as the sum of the elements in a sequence.
For example, In the sequence 1, 3, 5, 7, 9, …, 1 is the first term, 3 is the second term, 5 is the third term, and so on.
We have length of curtains as
1m, 1.25 m, 1.5 m,...
Now, from above the first term is 1.
Common difference, d= 1.25 - 1 = 0.25
So, the next length of curtain will be
= 1 + (4-1)0.25
= 1 + 0.75
= 1.75 m

Malcolm is feeling bags with rice he starts with a 5 1/4 pound container of rice and shells each bag with 5/8 pound of rice how many bags of rice can Malcolm fill
Answer:
8 2/5 bags of rice
Step-by-step explanation:
The above question is solved as;
5/8 pounds of rice = 1 bag of rice
5 1/4 pounds of rice = x bags of rice
Cross Multiply
5/8 pounds × x bags of rice = 5 1/4 pounds of rice × 1 bag of rice
x bags of rice = 5 1/4 pounds of rice × 1 bag of rice/ 5/8 pounds
x bags of rice = 5 1/4 ÷ 5/8
x bags of rice = 21/4 ÷ 5/8
x bags of rice = 21/4 × 8/5
x bags of rice = 42/5
x bags of rice = 8 2/5 bags of rice
Therefore, malcolm can fill 8 2/5 bags of rice.
