Answer: 50 km/hr
240 = rt
120 = rt1
120 = (r+10)t2
t1 + t2 = t - 2/5 ==> t2 = 1/2 t - 2/5
So you get
240 = rt
120 = (r + 10)(1/2 t - 2/5)
Solve the system
You het 50 km/hr

DUE soon! For an unknown parent function f(x), write a function g(x) that is:
vertically stretched by a factor of 2,
shifted up 5 units, and
shifted right 4 units.
Explain how your function accomplishes these transformations.
See I don't know if you can choose whichever parent function to start off.
Answer and Step-by-step explanation:
The parent function is just f(x) = x.
See, the transformations equation of a parent function is as follows:
f(x) = a(x - h) + k
Where:
a is the scaling factor,
h is the horizontal (left and right) changing factor, and
k is the vertical (up and down) changing factor.
So, now we apply the transformations to this parent function by writing it in function g(x).
Vertically stretch by factor of 2: g(x) = 2x
Shifted up 5 units: g(x) = 2x + 5
Shifted left 4 units: g(x) = 2(x - 4) + 5
g(x) = 2(x - 4) + 5 is the function.
This function accomplishes these transformation by having 2 be the scale factor, 4 be the horizontal shift, and 5 be the the vertical shift.

Hazel invested part of a Php10,000 inheritance in stocks paying 6.5%
simple interest annually. She invested the rest in bonds paying 4.25% simple
interest annually. If Hazel will receive Php 582.50 in interest after one year,
how much did she invest in stocks? How much did she invest in bonds?
Answer:
she invested $7013.33 in stocks and she invested $2986.7 in bonds?
Step-by-step explanation:
Let the amount invested in the stock= X
Let the amount invested in the bond= Y
For quantity equation,
X + Y = 10000 ............eqn(1)
✓We are told inheritance in stocks paying 6.5% simple interest = 0.065X
✓we are told She invested the rest in bonds paying 4.25% simple interest= 0.0425Y
The interest equation can be written as
0.065X + 0.0425Y = 582.50.........eqn(2)
We can make X subject of formula from eqn(1)
X= 10000 - Y
Substitute into eqn (2)
0.065(1000-Y) + 0.0425Y= 582.50
Multiply through by 10000
650(10000 - Y) + 425Y = 5825000
6500000 - 650Y + 425Y =5825000
Y= 2986.66
If we substitute Y into (X + Y )= 10000
X+2986.66= 10000
X= 7013.33
hence, she invested $7013.33 in stocks and she invested $2986.7 in bonds?

If one inch represents 6 feet, what dimensions would you use to make a scale drawing of a building 240 feet by 500 feet?
Answer: It would be 40 inches by 83 1/3 inches
Step-by-step explanation:
The dimensions on the scale drawings will be 40 inches by 83.34 inches.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that If one inch represents 6 feet. The dimensions of 240 feet by 500 feet in the scale drawing will be,
6 feet = 1 inch
1 feet = 1 / 6 inch
240 feet = ( 240 / 6 ) inches
240 feet = 40 inches
500 feet = ( 500 / 6 ) inches
500 feet = 83.34 inches

Answer:
The area of this shape is 252.
Step-by-step explanation:
Cut the right piece of the shape into a triangle of 90 degrees, which makes the shape divided into 2 triangles and 1 rectangle.
9 x 13 = 117 (rectangle part)
15 x 9 = 135, 135/2 = 67.5
15 x 9 = 135, 135/2 = 67.5
67.5 + 67.5 + 117 = 252
About 1.15 million people live in a circular region with a population density of 18075 people per kilometer. Find the radius of the region
Answer:
r = 5 km
Step-by-step explanation:
Given that,
The population in a circular region = 1.15 million
The population density of the region = 18075 people per kilometer
We need to find the radius of the region.
We can find the area of circular region i.e.
[tex]A=\dfrac{P}{d}\\\\A=\dfrac{1.15\times 10^6}{18075 }\\A=63.6\ km^2[/tex]
We know that the area of a circular region is given by :
[tex]A=\pi r^2\\\\\pi r^2=63.6\\\\r=\sqrt{\dfrac{63.6}{\pi}} \\\\r=4.49\ km[/tex]
or
r = 5 km
So, the radius of the region is equal to 5 km.
