Answer: 1249 hrs
Step-by-step explanation:
Sophia walked for 12 km to get to her aunt's house.
She did this at a speed of 5km/h which means that the time taken was:
Time = Distance / Speed
= 12 / 5
= 2.4 hours
2.4 in hours:
= 0.4 * 60 minutes
= 24 minutes
= 2 hours 24 minutes
If she left at 1025, she would arrive at:
= 1025 + 2 hours 24
= 1249 hrs
The length of a rectangle can be rpresented by the expression x+6. If the area of the rectangle is 2x^2+8x-24, what is the expression for the width.
Answer:
2(x − 2)
Step-by-step explanation:
The length of a rectangle can be rpresented by the expression x+6. If the area of the rectangle is 2x^2+8x-24, what is the expression for the width.
The formula for the area of a rectangle = Length × Width
Area of the rectangle = 2x² + 8x - 24
Length = x + 6
We can find the width of the rectangle be factoring the Area
Hence, factorising
2x² + 8x - 24
= 2(x − 2)( x + 6)
Therefore, the Width of the rectangle =2(x − 2)

one angle of a right triangle measures 80 degrees. what is the measure of the other acute angle
Answer:
10 degrees
Step-by-step explanation:
Since a right angle is 90 degrees in total, to find the missing degree subtract 80 from 90.
90-80=10 degrees

The ratio of potatoes to onions is 1:2 respectively if there are 14 onions how many photatoes are there
Answer:
7
Step-by-step explanation:
The ratio of potatoes to onions is 1:2, meaning there are twice as many onions as potatoes.
[tex]\frac{\text{potatoes}}{\text{onions}}=\frac{1}{2}=\frac{x}{14}[/tex]
The fraction on the right is equivalent to 1/2, so the numerator is half the denominator. There are 7 potatoes.

On the map, Winton ,California is located at(“ (2,10.5) in Lake Tahoe is located at (14,16). Each unit on the map equals 16.5 miles what is the approximate distance between the cities round to the nearest mile.
Answer:
The distance between the two
points on the map
is 225 units
Step-by-step explanation:
Firstly, we need to calculate the distance in units between the two locations on the map
What we have to use here is the distance formula
Mathematically, we have this as;
D = √(x2-x1)^2 + (y2-y1)^2
(x1,y1) = (2,10.5)
(x2,y2) = (14,16)
we have the distance as follows;
D = √(14-2)^2 + (16-10.5)^2
D = √(12^2 + 6.5^2)
D = √(186.25)
D = 13.65 units
now, from the question, 1 unit on the map represents a distance of 16.5 miles
thus, a distance of 13.65 units will be;
16.5 * 13.65 = 225.225
= 225 units

Step-by-step explanation:
Which ordered pair describes a point that is located 4 units to the left of the origin and 2 units below the x-axis?
Answer:
(-4,2)
Step-by-step explanation:
The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The ordered pair that describes a point that is located 4 units to the left of the origin and 2 units below the x-axis is (-4, -2)
What are coordinates in a graph?The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
The point is located 4 units to the left of the origin and 2 units below the
x-axis.
4 units to the left of the origin.
This means,
x = -4
2 units below the x-axis.
This means,
y = -2
The coordinate in the form of ordered pair is (-4, -2).
Thus,
The ordered pair that describes a point that is located 4 units to the left of the origin and 2 units below the x-axis is (-4, -2)

The cost of painting a circular traffic sign is $3.50 per square foot. How much, to the nearest dollar, will it cost to paint the sign if its diameter measures 36 inches?
Answer:
The answer is $25
Explanation:
area of a circle = pi x r^2
using 3.14 for pi
radius = 36/2 =18
area = 3.14 x 18^2 = 1017.36 square inches
1 sq ft = 144"
1017.36/144 = 7.065 sq ft
7.065*3.50 = $24.73 to the nearest dollar = $25

How many female statistics student ages must be obtained in order to estimate the mean age of all female statistics students
Answer:
Assume that we want 90% confidence that the sample mean is within one-half year of the population mean. Does it seem reasonable to assume that the ages of female statistics students have less variation than ages of females in the general population? The required sample size is . (Round up to the nearest whole number as needed.) Does it seem reasonable to assume that the ages of female statistics students have less variation than ages of females in the general population? A. Yes, because statistics students are typically younger than people in the general population. O B. No, because there is no age difference between the population of statistics students and the general population. O C.

The height of the cylinder is 18 meters and the volume of the cylinder is 4,374 cubic meters. What is the area of the base of the cylinder?
Answer:
242.76m^2
Step-by-step explanation:
Given data
Height=18m
Volume=4,374m^3
We know that the expression for the volume of a cylinder is
V=πr^2h
substitute
4374=3.142*r^2*18
4374=56.556*r^2
4374/56.556=r^2
77.339=r^2
r=√77.339
r= 8.79m
But the area of a circle is expressed as
A= πr^2
A=3.142*8.79^2
A=3.142*77.2641
A=242.76m^2
Hence the area of the base is 242.76m^2
