Answers
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

I'm not sure how your graphing tool works so I'll give you five or so coordinates
(-1,-7)
(1,-3)
(0,-5)
(2,-1)
(-2,-9)
Step-by-step explanation:
You first need to write an equation that you can graph
Knowing that the slope is two we can write the following equation
2x+b=y
We also know that when x=1 y=-3
This gives us 2*1+b=-3
which means that 2+b=-3
subtract 2 from both sides to figure out the b=-3
This means that the line you have to graph is 2x-5=y

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
Answers
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%

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
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
Answers
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

Step-by-step explanation:
First, you make the equation into slope intercept form, which is y=2/3x-3.
Then, because its perpendicular, the slope turns negative and upside down, so its -3/2, and then you insert the point (4, -1) to get the y intercept, which is -7. So you're answer is a.

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?
Answers
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-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)
Answers
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)

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.
Answers
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.
