At one time the aircraft is 150 m above the surface, the submarine is 25 m below the surface, and the underwater robotic vehicle is 186 m below the surface. What is the difference in height between the submarine and the aircraft
Answer:
[tex]175[/tex] meter is difference in height between the submarine and the aircraft
Step-by-step explanation:
The height of aircraft above the surface [tex]= 150[/tex] meter
Depth at which the submarine lies below the surface [tex]= 25[/tex] meter
Depth at which the underwater robotic vehicle below the surface [tex]= 186[/tex] meter
Difference in height between the submarine and aircraft is equal to
[tex]25 +150 = 175[/tex] meter

please help, i cant seem to get this right!!
Answer: 7ft
Step-by-step explanation:
The shape is a trapezium
Area of Trapezium= (1/2)(a+b)(h)
Area of Trapezium= 40sqft
a= x
b= 9ft
h= 5ft
40= (1/2)(x+9)(5)
40= (5(x+9)/2)
Cross multiply
80= 5(x+9)
80= 5x + 45
5x= 80-45
5x= 35
Divide both sides by 5
x= 7
how to I find x and y.
Answer:the example equation becomes "x + 10 - 15x = 20," which is then "-14 x + 10 = 20." Subtract 10 from each side, divide by 14 and you have end up with x = -10/14, which simplifies to x = -5/7. Plug in the x value in to the first equation to find out the y value.
Step-by-step explanation:
Answer:
x=9
y=14
Step-by-step explanation:
Your picture shows that the two angles are congruent so:
2[(2x+27)]=90
4x+54=90
4x=36
x=9
Your picture shows the two horizontal lines as congruent also so:
4y-19=y+23
4y-19+19=y-y+23+19
3y=42
y=14
the length and breadth of a rectangular plot is in the ratio of 4:3. if the perimeter is 140m, find the length and breadth of a rectangle
Answer:
l = 40 m and b = 30 m
Step-by-step explanation:
Let the length and breadth of a rectangle be 4x and 3x.
We know that,
The perimeter of a rectangle is given by :
P = 2(l+b)
140 = 2(4x+3x)
70 = 7x
x = 10
Length, l = 4x = 4(10) = 40 m
Breadth, b = 3x= 3(10) = 30 m
So, the length and breadth of a rectangle are 40 m and 30 m respectively.

Answer:
235
Step-by-step explanation:
94% of 250 is 235. To get 235, you can simply multiply 250 by .94
What is the solution set of this inequality? 3|p + 4| + 5 < 8 (–5, –3) (–3, 0) (0, –5) (3, 5)
Given:
The inequality is
[tex]3|p+4|+5<8[/tex]
To find:
The solution set for the given inequality.
Solution:
We have,
[tex]3|p+4|+5<8[/tex]
[tex]3|p+4|<8-5[/tex]
[tex]3|p+4|<3[/tex]
Divide both sides by 3.
[tex]|p+4|<1[/tex]
It can be written as
[tex]-1<p+4<1[/tex]
Subtracting 4 from each side, we get
[tex]-1-4<p+4-4<1-4[/tex]
[tex]-5<p<-3[/tex]
The solution set of the given inequality is (-5,-3).
Therefore, the correct option is A.
Water flows through a pipe at a rate of 10 cubic meters per day. Express this rate of flow in milliliters per minute. Round your answer to the nearest whole number.
Answer:
6,944 ml/minute
Step-by-step explanation:
According to the scenario, calculation of given data are as follows,
Flow rate per day = 10 cubic meters
here, 1 cubic meter = 1,000,000 millilitre
so, 10 cubic meter = 10,000,000 millilitre
Minutes in a day = (60 × 24) minutes = 1,440 minutes
So, flow rate for 1,440 minutes = 10,000,000 milliliters
Flow rate for 1 minute = 10,000,000 milliliters ÷ 1,440 minutes
Flow rate per minute = 6,944.44 milliliters / minute or 6,944ml/minute
I ordered 4 new CD's by mail. Each CD costs the same amount and there was an additional $5 shipping charge that brought the total to $33. Write and solve the equation to find the cost of one CD.
Answer:
$7
Step-by-step explanation:
I ordered 4 new CD's by mail. Each CD costs the same amount and there was an additional $5 shipping charge that brought the total to $33. Write and solve the equation to find the cost of one CD.
Let us represent the cost of 1CD = x
Total cost = $5 + 4x
= 5 + 4x
Total cost = $33
Hence, our Equation is given as:
33 = 5 + 4x
4x = 33 - 5
4x = 28
x= 28/4
x = $7
The cost of 1 CD = $7

Find the measure of the missing angles.
Step-by-step explanation:
c=144°(vertically opposite angle)
b+c=180°(straight angle)
b+144=180
b=180-144
b=36°
There are only green yellow blue cubes in a bag
Answer:
1 ÷ 11
Step-by-step explanation:
The computation is shown below:
let us assume the yellow cubes be x
So, blue cubes be 2x
And, green cubes be 2x (4) 8x
Now the ratio is
Yellow: Blue: green
x:2x:8x
1:2:8
Now the probability of yellow cubes is
= 1 ÷ (1 + 2 + 8)
= 1 ÷ 11

-10 x + 4 = 52 x=___ help
Answer: x=-4.8
Step-by-step explanation:
Given
-10x+4=52
Subtract 4 on both sides
-10x+4-4=52-4
-10x=48
Divide -10 on both sides
-10x/-10=48/-10
x=-4.8

(5x + 4y = 24
2x – 7y = 26
Answer:
B.
Step-by-step explanation:
If you calculate the sum of both you get:
5x + 2x + 4y - 7y = 24 + 26
7x - 3y = 50, which is B
Bryce practice his piano for 1/3 hour each day. How many hours each week does Bryce been practicing piano?
Answer: 2¹/₃ hours per week
Step-by-step explanation:
Bryce practices his piano for 1/3 hours each day.
The number of days in a week is 7 days so to find out the number of hours he practices per week, multiply the number of hours practiced per day by 7.
= 1 /3 * 7
= 7 / 3
= 2¹/₃ hours per week
,8. If A= {x:x is a factor of 72}
B= {x:72x+3<2x --3}.
C= {x:x<20} and A, B, Ccu.
Where 11 = {integers), list the
elemen:s of AnBnc.
(WAEC) pls help thx
Answer:
No element is common to all the sets
AnBnc = { }
Step-by-step explanation:
If A= {x: xis a factor of 72}
A = {2, 3, 4, 6, 8, 9, 12, 18, 36, 72}
If B= {x: 72x+3<2x-3).
72x+3 <2x-3
72x - 2x < -3-3
70x < -6
x < -6/70
x < -3/35
x< -0.0857
If
C= {x:x<20}
C = {-∞, 19}
The intersection of the sets AnBnc = {} i.e an empty set
Note that intersection means all the elements common to the three sets
help asap i’ll be giving a brainliest to the person with the correct answer
Answer:
All of the above.
Step-by-step explanation:
By looking at the graph and taking point x at 4 and y at around 300. This shows us the precise rate of the graph which is when x = 4, y is equal to 300.
Now if we substitute the x as 4 in any of the equations we will get values larger than 300. Therefore, all the equations have a greater rate of change.
y = 85(4) = 340 (Greater)
y = 50(4) + 150 = 350 (Greater)
y = 65(4) + 100 = 360 (Greater)
Find the y-intercept:

i need help 10 less than the sum of p and m
write the expression
Answer:
p + m - 10 is your expression
Step-by-step explanation:
Answer:
p + m - 10
Step-by-step explanation:
Hi , expressions are easy you just need to know how to read these weird word problems they give us.
Let us look at some key words and change them into symbols and not words.
10 less
This means it will most likely be a -10 somewhere
The sum of p and m
This would mean addition, so p + m
With this info we can form an expression.
p + m - 10
This is how I would write it.
Since the sum of p and m is (p+m) and the 10 less is the (-10)
You would add the p and m to find their sum and then take off 10 for the 10 less.
I hope this helps!

-4(y-2)=12
what is y
Answer:
y= -1
Step-by-step explanation:
Answer:
The answer would be y= -1
Step-by-step explanation:
When we have a number outside the parenthesis we do the rainbow method where we multiply the number on the outside of the parenthesis to the numbers inside the parenthesis so
-4*y= -4y and -4*-2=8
-4y+8=12
-4y=4
y=-1
