Answer:
1 Hour and 20 minutes
Step-by-step explanation:
Time = Distance ÷ Speed
The total time taken by Andy is (1.25 + 1.5) 2.75 hrs or 165 minutes and this can be determined by using the formula of speed.
Given :
Andy cycles a distance of 30 km at an average speed of 24 km/h. He then runs a distance of 12 km at an average speed of 8 km/h.The formula of speed is used to determine the time taken by Andy to cover the total distance. The formula of speed is given by:
[tex]\rm s = \dfrac{D}{t}[/tex]
where 's' is the speed, 'D' is the distance and 't' is the time.
Now, the time taken by Andy to cover the distance of 30 Km with the speed of 24 Km/hr is:
[tex]\rm 24 = \dfrac{30}{t}[/tex]
[tex]t = \dfrac{30}{24}[/tex]
t = 1.25 hrs.
Now, the time taken by Andy to cover the distance of 12 Km with the speed of 8 Km/hr is:
[tex]\rm 8 = \dfrac{12}{t}[/tex]
[tex]t = \dfrac{12}{8}[/tex]
t = 1.5 hours.
So, the total time taken by Andy is (1.25 + 1.5) 2.75 hrs or 165 minutes.

Answer:
3x² * (6x² + 4x - 8) = 18x⁴ + 12x³ - 24x²
2x * (9x³ + 6x² - 12x) = 18x⁴ + 12x³ - 24x²
x² * (18x² + 12x - 24) = 18x⁴ + 12x³ - 24x²
6x² * (3x² + 2x - 4) = 18x⁴ + 12x³ - 24x²
Step-by-step explanatation:
Let's set unknown variables as y (and y₁, y₂, etc)
Question 1:
y * (6x² + 4x - 8) = 18x⁴ + 12x³ - 24x²
So, divide both sides by (6x² + 4x - 8)
y = 3x²
Question 2:
2x * (9x^y₁ + y₂*x^y₃ - y₄*x) = 18x⁴ + 12x³ - 24x² '
Divide both sides by 2x.
(9x^y₁ + y₂*x^y₃ - y₄*x) = 9x³ + 6x² -12x
y₁ = 3, y₂ = 6, y₃ = 2, y₄ = 12
Question 3:
x^y * (18x² + 12x - 24) = 18x⁴ + 12x³ - 24x²
Divide both sides by (18x² + 12x - 24)
x^y = x²
Question 4:
y₁ * x^y₂ * (3x² + 2x - 4) = 18x⁴ + 12x³ - 24x²
Divide both sides by (3x² + 2x - 4)
y₁ * x^y₂ = 6x²
y₁ = 6, y₂ = 2

A certain man has a negative balance of P250 in his back account b) suppose he deposits P300 in his back account ,what is the current balance in his account?
Answer: $50
Step-by-step explanation:
From the question, we are informed that a certain man has a negative balance of P250 in his back account and that he then deposits P300 in his back account.
The current balance in his account? will then be gotten by adding the negative balance of $250 to the $300 deposited. This will be:
= -$250 + $300
= $50
Therefore, his current balance will be $50

figure is the image?
O AFGH is the image and A ABC is the pre-image
AFGH is the pre-image and AABC is the image.
Both triangles are images.
The image cannot be determined from the graph.
Given:
A graph that contains image and preimage.
To find:
Which figure is the preimage and which figure is the image.
Solution:
Initial figure is known as preimage and translated figure is known as image.
It is given that a triangle was translated 4 units down. It means, the upper triangle is preimage and the lower triangle is the image.
So, ΔFGH is the pre-image and ΔABC is the image.
Therefore, the correct option is B.
the answer is B :0

As part of a training program for the Boston Marathon, a runner wants to build endurance by running at a rate of 12 mph for 15 min. How far will the runner travel in that time period? _ mi
The distance travelled by the runner running at a rate of 12 mph for 15 min is 3 miles.
Speed is the ratio of distance travelled to time taken. Speed is given by:
Speed = distance/time
Given that the runner is running at a rate of 12 mph for 15 min, hence:
speed = 12 mph, time = 15 min * 1/60 min per hour = 0.25 hours.
Hence:
Speed = distance/time
12 mph = distance/0.25 hours
distance = 3 miles
The distance travelled by the runner running at a rate of 12 mph for 15 min is 3 miles.

Answer:
3,364
Step-by-step explanation:
8 + 25 x 2
To solve this one, you multiply first according to PEMDAS. So,
25*2= 50
It is now 8+50 so you add that and you get 58
Now 58 with a power of 2 can als be written as 58^2
Basically you multiply 58 two times.
58*58=3,364

Use the figure below to solve for the value of x.
Given:
A figure of a right triangle and an altitude form the right angle vertex to hypotenuse.
To find:
The value of x.
Solution:
From the given figure, it is clear that the altitude divides the hypotenuse in two segments x and 8.
Length of altitude = 18
If an altitude divide the hypotenuse in 2 segments, then according to the geometric mean theorem, the length of the altitude is the geometric mean of two segments of hypotenuse.
By using geometric mean theorem, we get
[tex]18=\sqrt{x\times 8}[/tex] [tex][\because \text{Geometric mean of }a,b,c:b=\sqrt{ac}][/tex]
[tex]18^2=8x[/tex]
[tex]324=8x[/tex]
Divide both sides by 8.
[tex]\dfrac{324}{8}=x[/tex]
[tex]40.5=x[/tex]
Therefore, the value of x is 40.5.

find the volume of a prism 5 feet tall whose base is a right triangle with leg lengths 3/2 feet and 9 feet
Answer:
33.75
Step-by-step explanation:
The volume of a right triangle prism is 33.75 cubic feet which is 5 feet tall.
It is given that the prism is 5 feet tall whose base is a right triangle with leg lengths of 3/2 feet and 9 feet.
It is required to find the volume of the prism.
What is volume?It is defined as a three-dimensional space enclosed by an object or thing.
We have 5 feet tall prism ie.
height of the prism h = 5 feet
and base b = 3/2 feet
and length = 9 feet
We know the volume of the right triangle prism is given by:
[tex]\rm V = \frac{b\times h\times l }{2}[/tex]
Putting the values of b, h, and l, we get:
[tex]\rm V =\frac{\frac{3}{2} \times 5\times 9}{2}[/tex][tex]\rm V = \frac{3 \times 5\times 9}{2\times2} \Rightarrow \frac{135}{4}[/tex]
V = 33.75 cubic feets
Thus, the volume of a right triangle prism is 33.75 cubic feet which is 5 feet tall.

Evaluate the logarithm.
log 0.00001
The logarithm base 10 of 0.00001 is -5.
The logarithm of 0.00001 can be evaluated using the base 10 logarithm, commonly denoted as log10.
In this case, log10(0.00001) is asking "What power of 10 gives us 0.00001?"
To understand this, let's rewrite 0.00001 in scientific notation.
0.00001 can be expressed as 1 x 10⁻⁵, where -5 is the exponent.
Therefore, log10(0.00001) = -5.
This means that 10 raised to the power of -5 equals 0.00001.
