Step-by-step explanation:
-9m + -10m = -95
-19m = -95
m = m
The required equation is (-9m) + (-10m) = -95 and the solution is m = 5.
Equation:The required sign for the sum is "+".
The sum of -9m and -10m is:
[tex]Sum=(-9m)+(-10m)[/tex]
It is given that the sum of -9m and -10m is -95.
[tex](-9m)+(-10m)=-95[/tex]
[tex]-9m-10m=-95[/tex]
[tex]-19m=-95[/tex]
Now, divide both sides by -19 to solve the equation.
[tex]\dfrac{-19m}{-19}=\dfrac{-95}{-19}[/tex]
[tex]m=5[/tex]
Therefore, the required equation is (-9m) + (-10m) = -95 and the solution is m = 5.

If you place a 36-foot ladder against the top of a building and the bottom of the ladder is 32 feet from the bottom of the building, how tall is the building? Round to the nearest tenth of a foot.
Answer:
16.5
Step-by-step explanation:
36^2-32^2 =272
sqrt272 =16.5
The height of the building is approximately 16.5 feet.
What is the Pythagoras theorem?The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.
Given that, place a 36-foot ladder against the top of a building and the bottom of the ladder is 32 feet from the bottom of the building.
So, hypotenuse of the triangle is 36 feet and base of the triangle is 32 feet.
Let h be the height of the building.
Now, 36²=32²+h²
1296=1024+h²
h²=1296-1024
h²=272
h=16.5 feet
Therefore, the height of the building is approximately 16.6 feet.

If Eli bikes at a constant speed of 15 feet per second,
which of the following is closest to how many miles
he will bike in 2 hours? (1 mile = 5.280 feet;
1 hour = 60 minutes; 1 minute = 60 seconds)
A) 0.3
B) 10.2
C) 11.0
D) 20.5
Eli will bike 20.5 miles in 2 hours
How to solve the problem?Constant speed given is 15 feet/sec1 mile = 5.280 feet is given.1 hour = 60 minutes is given.1 minute = 60 seconds is given.We need to find the number of miles bike by Eli,
Firstly ,
We know 1 minute = 60 seconds
Then 15 feet / seconds = 15*60 = 900 feet
Eli bikes 900 feet in one minute
Now, We know
1 hour = 60 minutes
900*60=54000 feet
In 1 hour Eli bikes 54000 feet
In 2 hours Eli bikes 54000*2 = 1,08,000 feet
Now for converting feet into miles
1 mile = 5.280 feet
For 1,08,000 feet
1,08,000 / 5.280
= 20.4545 ≈ 20.5
Hence In 2 hours Eli bikes 20.5 miles

27 solid iron spheres, each of radius 'xcm'ate melted to form a sphere with radius 'ycm',find the ratio x:y
Answer:3:1
Step-by-step explanation:
Given
There are 27 solid spheres of radius x cm
The volume of a sphere is [tex]\frac{4}{3}\pi r^3[/tex]
The volume of 27 old spheres is the same as the volume of a new sphere
The volume of the old spheres is
[tex]V_o=\dfrac{4}{3}\pi x^3[/tex]
The volume of a new sphere is
[tex]V_n=\dfrac{4}{3}\pi y^3[/tex]
Now,[tex]V_o=V_n[/tex]
[tex]\Rightarrow 27\times \dfrac{4}{3}\pi x^3=\dfrac{4}{3}\pi y^3\\\\\Rightarrow (\dfrac{x}{y})^3=27\\\\\Rightarrow \dfrac{x}{y}=3[/tex]
A man can row at 9km/h in still water. He rows 1.5km upstream and back again. The stream flows at 3km/h. What is his average speed for the whole trip?
Answer:
8km/h
Step-by-step explanation:
The computation of the average speed is shown below:
In the case of upstream, the speed is
= 9 - 3
= 6km/h
And, the time would be
= 1.5km ÷ 6
= 0.25h
In the case of downstream, the speed is
= 9 + 3
= 12
The time would be
= 1.5km ÷ 12
= 0.125h
Now the average speed is
= 3 ÷ (0.25 + 0.125)
= 8km/h

please help find the central angle and perimeter !
Step-by-step explanation:
We will have the following
*First: We have that the area of a sector of a circle is given by the expression:
A = r²a/2
Here r is the radius and alpha is the central angle.
*Second: We determine the central angle as follows:
[tex]36\pi =[/tex]
(12)²a/2 ➡️ a = 36í•2/(12) ²➡️
[tex]a = \frac{1}{2} \pi[/tex]
So, the central angle has a measurement of 1/2 pi.
Third: We determine the perimeter of the sector as follows:
First: we determine the arc length with two times the radius, that is:
p = 2(12) +
[tex]6\pi[/tex]
➡️ p = 24 +
[tex]6\pi[/tex]
So, the perimeter of the sector is 24+ 6pi meters [ Approximately 43 meters].

A certain brand of flood lamps has a lifetime that is normally distributed with a mean
of 3,750 hours and a standard deviation of 300 hours.
(a) What proportion of these lamps will last for at least 4,000 hours?
(b) What proportion of these lamps will last between 3,600 and 4,000 hours?
(c) What proportion of these lamps will last less than 3,800?
Answer:
0.83
Step-by-step explanation:
(a) z = (x - mean) / sd = (4000 - 3750) / 300 = 0.83
This corresponds to 0.7967 from the z-table, which represents how many last less than 4000 hours, so the answer is 1 - 0.7967 = 0.2033
(b) It will be P(x<4000) - P(x>3600) = 0.7967 - whatever the corresponding value is.
(c) same procedure as (b).
(d) 2% above corresponds to 0.02 which is a z-score of -2.05
-2.05 = (x - 3750) / 300
x = 3135
