Complete question :
In Hawaii a volcano is about to explodel At 6:00 am a device placed inside the volcano
measures the temperature at 69.5 degrees Celsius. Every 3 minutes the temperature
rises 1/5 a degree. If the Volcano explodes at 145.5 degrees Celsius how many hours do
they have to evacuate a nearby city?
Will Mark BRAINLIEST to the correct answer
Answer:
19 hours
Step-by-step explanation:
Given that:
Temperature of volcano at 6:00 am = 69.5°C
Average rise in temperature per 3 minute = 1/5
Hence, rise in temperature per minute = 0.0666666°C
Temperature at which volcano will explode = 145.5°C
Hence, change in temperature :
(145.5°C - 69.5°C) = 76°C
Hence, temperature will have to rise by 76°C
Rise in temperature / rate of temperature increase
= 76°C / 0.0666666°C
= 1140.0011 minutes
= 1140.0011 / 60
= 19.0000019 hours
= 19 hours

Given:
In triangle ABC, Q is the centroid and FQ=9.
To find:
The length of FC and QC.
Solution:
We know that, centroid is the intersection point of medians of a triangle and medians divide teach other in 2:1. So, centroid divided each median in 2:1.
CF is a median and Q is the centroid. So,
[tex]QC:FQ=2:1[/tex]
Let the length of QC and FQ are 2x and x respectively.
We have, FQ=9.
[tex]x=9[/tex]
Now,
[tex]QC=2x[/tex]
[tex]QC=2(9)[/tex]
[tex]QC=18[/tex]
And,
[tex]FC=FQ+QC[/tex]
[tex]FC=9+18[/tex]
[tex]FC=27[/tex]
Therefore, the length of FC is 27 units and length of QC is 18 units.

Raj plotted point L in the coordinate plane below.
On a coordinate plane, point L is 1.5 units to the left and 4 units up.
He says that the plotted point is (4, negative 1.5). What is Raj’s error?
The x-coordinate should be -4.
The y-coordinate should be 1.5.
The x- and y-coordinates are switched.
Both coordinates should be positive.
Answer:
The x- and y-coordinates are switched
Step-by-step explanation:
Here, we want to identify the error in the plot
1.5 units to the left, that is negative x-axis (-1.5)
4 units up is 4
So the coordinate point is (-1.5,4)
So the error on what he gave was that both coordinates were switched

A right-angled triangle has sides of lengths (x+5)cm, (x-3)cm and 9cm. Calculate the value of x. Give your answer to 3 significant figures. (Quadratic Formula)
Answer:
x = (3.95 and -5.95)
Step-by-step explanation:
Given:
Hypotenuse = 9 cm
Perpendicular = (x+5) cm
Base = (x-3) cm
Find:
Value of x
Computation:
Using Pythagoras theorem
Hypotenuse² = Perpendicular² + Base²
9² = (x+5)² + (x-3)²
81 = x² + 25 + 10x + x² + 9 - 6x
2x² + 4x - 47 = 0
Quadratic Formula
x = [-b±√b²-4ac] / 2a
x = [-4±√16+376] / 2(2)
x = (3.95 and -5.95)
On the second day of a hiking trip the tourist covered a 17% bigger distance than on the first day . By how many percent of their average speed change from the first to the second day if on the second day they were hiking for a 20% longer time
Answer:
2.5%
Step-by-step explanation:
x=distance y=time
x has been increased by 17%
100%+17% = 117%
y has been increased by 20%
100%+20%=120%
Now let's make the percentages into decimals. 117%=1.17 120%=1.2
To find the average speed you do the distance traveled divided by the time taken.
Average speed = 2.5%

Question:
A paintball court charges an initial entrance fee plus a fixed price per ball. P represents the total price (in dollars) as a function of the number of balls used n.
P=0.80n+5.50
What is the price for 10 balls, not including the entrance fee?
Answer:
$8
Step-by-step explanation:
We are given the function:
P=0.80n+5.50
Where n represents the number of balls. From this function, the entrance fee = 5.50
We are asked to calculate the price for 10 balls without the entrance fee. This is given as:
0.80n = 0.80 × 10 balls
= $8
The price for 10 balls, not including the entrance fee is $8
Answer:
The answer is 8

What is thw Domain and the Range
The domain is the x value and the range is the y value.
Because x is a variable it can be any real number so the domain would be negative infinity to infinity.
Because the domain is negative infinity to infinity, then the range is also negative infinity to infinity.
In an experiment , the temperature of a solution is -5/8 degrees. The temperature drops 1 1/2 degrees. What is the temperature after the drop?
Answer:
- 2 1/8 degrees
Step-by-step explanation:
Given
Initial temperature of a solution = -5/8 degrees
Amount drop = 1 1/2 degrees
Temperature after the drop = -5/8 - 1 1/2
Temperature after the drop = -5/8 - 3/2
Temperature after the drop = -5-12/8
Temperature after the drop = -17/8
Hence the temperature after the drop is - 2 1/8 degrees

A right angle is shown divided into two parts. The measure of one part of the right angle is 30 degrees. The measure of the other part is 4x.
15
30
45
60
Answer:
x = 15
Step-by-step explanation:
We are told that a right angle is divided into two parts
A right angle = 90°
Part A = 30°
Part B = 4x
Hence:
30° + 4x = 90°
Collect like terms
4x = 90° - 30°
4x = 60°
4x = 60/4
x = 15
Therefore, the value of x = 15

Step-by-step explanation:
Here's a trick:
Find the last number of the equation and look at your factors to see which numbers you can multiply to get that answer
in this case the last number of x^3-8x^2+17x-10 is -10
*IF IT HAS A NEGATIVE, ALWAYS REMEMBER TO INCLUDE IT*
Then look at the options and see what numbers can get you -10 but include the factor that they give you.
in this case C has the numbers as -1×-5×-2 gives you -10
now to check by using the box method, which is much easier to do, and put pick 2 of those factors and check if it's right

Henry received $500 for his birthday which he intends to invest in an account that pays simple interest at the rate of 12% per year. How much will be in the account
Answer:
$560
Step-by-step explanation:
Given that :
Principal, P= $500
Interest rate, r = 12% per year
Amount in account after 1 year
Time = 1 year
Using the relation :
A = P(1 + rt)
A = final amount in account
A = $500(1 + 0.12(1))
A = $500(1 + 0.12)
A = $500(1.12)
A = $560

Select the function that's represented in the graph.
Question options:
A)
ƒ(x) = –(x + 2)² – 3
B)
ƒ(x) = (x + 2)² – 3
C)
ƒ(x) = –(x – 2)² – 3
D)
ƒ(x) = (x – 2)² – 3
Answer: A
Step-by-step explanation:
If you look at option A and ignore the -(x+2)^2, it would say f(x) = -3.
So the vertex has y-coordinate -3.
Because the coefficient of -(x+2)^2 is negative, the graph opens downward.
Because it says -(x+2)^2 instead of -(x-2)^2, it will be on the left side of the graph.
The graph meets all of these conditions.
The graph described in option B opens upwards.
The graph described in option C opens upwards and the vertex is in the fourth quadrant.
The graph described in option D opens downwards, but the vertex is in the fourth quadrant.

Quadrilateral JKLM has vertices J(–7, –2), K(–2, –2), L(–3, –4), and M(–6, –4). Find the midpoints of each of the sides JM and KL.
Step-by-step explanation:
X-value of Midpoint of J(-7, -2) and M(-6, -4)
= [(-7) + (-6)] / 2 = -6.5.
Y-value of Midpoint of J(-7, -2) and M(-6, -4)
= [(-2) + (-4)] / 2 = -3.
X-value of Midpoint of K(-2, -2) and L(-3, -4)
= [(-2) + -3)] / 2 = -2.5.
Y-value of Midpoint of K(-2, -2) and L(-3, -4)
= [(-2) + (-4)] / 2 = -3.
We have (-6.5, -3) and (-2.5, 3).
The correct answer is Option D.
