Answer:
15 miles far from your house.
Step-by-step explanation:
By using Pythagorean Theorem
H² = P² + B²
=> 12² + 9² = H²
=> 144 + 81 = H²
=> 225 = H²
=> √225 = H
=> 15 = H

A cup of hot water is left out to cool. The water is currently 19°C above room temperature. If the heat difference decreases by 5% every minute, what will the difference be in 13 minutes?
Answer:
The difference will be 0.65 °C above room temperature after 13 minutes.
The difference in temperature in 13 minutes will be 6.65° C.
What is an expression?The expression is defined as the relations of the numbers and the variables combined together to form the equation by the use of mathematical algebraic symbols like equal greater than or less than.
Given that a cup of hot water is placed on the counter to cool. The temperature of the water is currently 19°C above room temperature. If the temperature difference falls by 5% every minute.
The heat difference will be calculated as:-
Total decrease = 13 x 5 = 65%
[tex]H = 19\times\dfrac{100-65}{100}[/tex]
[tex]H = 19\times \dfrac{35}{100}[/tex]
H = 19 x 0.35
H = 6.65°
Therefore, the temperature will be 6.65°.

The playground pictured here is having rubber flooring installed to help protect children against injuries from falls. If the cost, including installation, is $8.00 per square foot, what is the total cost of installing the surface?
Answer:
$6,672
Step-by-step explanation:
Area of Playground
Area (rectangle) + 2 x Area (semicircle)26 x 20 + 2 x 3.14 x 10² x 1/2520 + 314834 square feetCost
$8.00 per square feet$8 x 834$6,672Answer:
Using π: $6,673.27 (nearest cent)
Using π = 3.14: $6,672
Step-by-step explanation:
Separate the figure into a rectangle and two semicircles.
Area of a rectangle = width × length
= 20 ft × 26 ft
= 520 ft²
Area of a semicircle = 1/2 π r²
= 1/2 π · 10²
= 50π ft²
⇒ Total area = area of rectangle + (2 × area of semicircle)
= 520 + (2 × 50π)
= (520 + 100π) ft²
⇒ Total cost = area × cost
= (520 + 100π) × $8
= $6,673.27 (nearest cent)
**using π = 3.14**
Total cost = (520 + 100 × 3.14) × $8 = $6,672

Let's solve this problem step-by-step:
1. Let's put this in a fraction format:
6834 ÷ 17 = [tex]\frac{6834}{17}[/tex]
2. Now we know 6834 = 6800 + 34
⇒ so:
[tex]\frac{6834}{17} =\frac{6800+34}{17} =\frac{6800}{17} +\frac{34}{17}[/tex]
3. Now let's convert the fractions to denominators
[tex]\frac{6800}{17} +\frac{34}{17} =[/tex] (6800 ÷ 17) + (34 ÷ 17)
Let's check:
6834 ÷ 17 = 402(6800 ÷ 17) + (34 ÷ 17) = (400) + (2) = 400 + 2 = 402
Answer: (6800 ÷ 17) + (34 ÷ 17) or Choice (C)

The prices of commodities X,Y,Z are respectively x, y, z, rupees per unit. Mr. A purchases 4 units of Z and sells 3 units of X and 5 units of Y. Mr. B purchases 3 units of Y and sells 2 units of X and 1 units of Z. Mr. C purchases 1 units of X and sells 4 units of Y and 6 units of Z.in this process A and C earn Rs. 6000 and Rs. 13000 respectively. While B neither lose nor gain. Find the prices per unit of the three commodities by using appropriate method.
please help me!!
Answer:
[tex](x,y,z)=(1477, 1464, 1437)[/tex]
Step-by-step explanation:
Consider the selling of the units positive earning and the purchasing of the units negative earning.
Case-1:Mr. A purchases 4 units of Z and sells 3 units of X and 5 units of YMr.A earns Rs6000So, the equation would be
[tex]3x + 5y - 4z = 6000[/tex]
Case-2:Mr. B purchases 3 units of Y and sells 2 units of X and 1 units of ZMr B neither lose nor gain meaning he has made 0₹hence,
[tex]2x - 3y + z = 0[/tex]
Case-3:Mr. C purchases 1 units of X and sells 4 units of Y and 6 units of ZMr.C earns 13000₹therefore,
[tex] - x + 4y + 6z = 13000[/tex]
Thus our system of equations is
[tex]\begin{cases}3x + 5y - 4z = 6000\\2x - 3y + z = 0\\ - x + 4y + 6z = 13000\end{cases}[/tex]
Solving the system of equations:
we will consider elimination method to solve the system of equations. To do so ,separate the equation in two parts which yields:
[tex]\begin{cases}3x + 5y - 4z = 6000\\2x - 3y + z = 0\end{cases}\\\begin{cases}2x - 3y + z = 0\\ - x + 4y + 6z = 13000\end{cases}[/tex]
Now solve the equation accordingly:
[tex]\implies\begin{cases}11x-7y=6000\\-13x+22y=13000\end{cases}[/tex]
Solving the equation for x and y yields:
[tex]\implies\begin{cases}x= \dfrac{223000}{151}\\\\y= \dfrac{221000}{151}\end{cases}[/tex]
plug in the value of x and y into 2x - 3y + z = 0 and simplify to get z. hence,
[tex]\implies z= \dfrac{217000}{151} [/tex]
Therefore,the prices of commodities X,Y,Z are respectively approximately 1477, 1464, 1437

What is the gradient of the blue line?
X
Answer:
1/4
Step-by-step explanation:
Using points (0 ; 1) and (4 ; 2)
m= y2-y1 / x2-x1
= 2-1 /4-0
= 1/4
The gradient of the blue line is, 1/4
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Two points on the blue line are (3, -3) and (3, -6).
Now,
Since, The equation of line passes through the points (4, 2) and (8, 3).
So, We need to find the slope of the line.
Hence, Slope of the line is,
m = (y₂ - y₁) / (x₂ - x₁)
m = (3 - 2) / (8 - 4)
m = 1 / 4
m = 1/4
Thus, The gradient of the blue line is, 1/4

The radius of a circle is 9 feet. What is the Area and the circumference of the circle?
Answer:
area is 254.34 circumference is 56.52
Step-by-step explanation:
To find the area you need to follow the formula r^2(pi)
so it would be 9x9x3.14 which is 254.34
to find circumference you need to find diameter which is double the radius (9x2) so the diameter is 18
To find circumference to need to do radius x pi
18x3.14 is 56.52
