Answer:
The equation that can be used to determine m, the number of minutes it will take the helicopter to reach the hospital is [tex]172 \times (\frac{m}{60} ) = 80[/tex].
Step-by-step explanation:
We are given that a medical rescue helicopter is flying at an average speed of 172 miles per hour toward its base hospital. At 2:42 p.m., the helicopter is 80 miles from the hospital.
As we know that the Distance-Speed-Time formula is given by;
[tex]\text{Distance} = \text{Speed}\times \text{Time}[/tex]
Here, Distance = 80 miles
Speed = 172 miles per hour
Time = m (the number of minutes)
Firstly, as we can see that the speed is in miles per hour but the time is in minutes, so we will convert the time in hours, i,e;
Time = [tex]\frac{\text{m}}{60} \text{ (in hours)}[/tex]
So, [tex]\text{Distance} = \text{Speed}\times \text{Time}[/tex]
[tex]80 = 172 \times (\frac{\text{m}}{60})[/tex]
[tex]\text{m} = \frac{80 \times 60}{172}[/tex]
m = 27.91 ≈ 28 minutes.
Hence, it will take 28 minutes for the helicopter to reach the hospital.

find the missing end point if H is the midpoint of PS. P(2,5) and H (3,4) find S (endpoint)
Answer:
(4,3)
Step-by-step explanation:
To find the midpoint add the end points and divide by 2
P(2,5) S ( sx, sy) and the midpoint is and H (3,4)
X coordinate
( 2+ sx) /2 = 3
Multiply each side by 2
2+sx = 3*2
2+sx = 6
Subtract 2
sx = 4
Y coordinate
( 5+ sy) /2 = 4
Multiply each side by 2
5+sy = 4*2
5+sy = 8
Subtract 5
sy = 3
The end point is
(4,3)
Answer:
[tex]\huge \boxed{\mathrm{S(4,3)}}[/tex]
Step-by-step explanation:
We can use the midpoint formula to solve for the endpoint.
[tex]\displaystyle m=(\frac{x_1+x_2 }{2} ,\frac{y_1+y_2}{2} )[/tex]
The midpoint of PS is H.
[tex]\displaystyle \frac{2+x_2 }{2} =3 \ \ \ \frac{5+y_2}{2} =4[/tex]
[tex]\displaystyle 2+x_2 =6 \ \ \ 5+y_2 =8[/tex]
[tex]x_2=4 \ \ \ y_2=3[/tex]

estimate the height of a tree using the following measurements:height of the rod:180 cm,length of the shadow of the rod is 116 cm,length of the shadow of the tree:840 cm,calculate the height of the tree
Answer:
1303.45 cm
Step-by-step explanation:
The triangles formed by a rod and its shadow and a tree and its shadow are similar triangles, so the ratios of their heights to the lengths of their shadows are equal.
Let x be the height of the tree. Setting the ratios equal, we get:
180/116 = x/840
Solve for x:
x = 840 * (180/116)
x ≈ 1303.45 cm

In a birthday party all children got 3 candy's but 1 child got 2 candy's then if all children got 2 candy's then 8 candy is remaining how many andy's in total
Answer:
22
Step-by-step explanation:
If there are n children, the number of candies in the first distribution is ...
3n +1
If the same number of candies is distributed to the same n children, then the second distribution tells us ...
2n +8 = 3n +1
7 = n . . . . . . . . . subtract 2n+1. This is the number of children.
The number of candies is ...
3(7) +1 = 22
There were 22 candies in total.

W/5=3 what does w equal
Answer:
w=15
Step-by-step explanation:
w/5=3
multiply by 5 on both sides
w=3*5
∴ w=15
Answer:
15
Step-by-step explanation:
If something over 5 is 3, that means w divided by 5 equals 3.
That can bve translated to W=3 times 5, which is 15.
Therefore, W= 15.
A cylindrical storage vessel is7cm in diameter and 6m long. Find its volumes. 211
231

271
Answer:
[tex] \boxed{ \huge{ \boxed{ \sf{ \bold{231 \: {cm}^{3} }}}}}[/tex]Option B is the correct option.
Step-by-step explanation:
Given,
Diameter ( d ) = 7 cm
Radius is just half of diameter.
Radius ( r ) = 7 / 2 = 3.5 cm
Height ( h ) = 6 cm
Now, let's find the volume:
Volume of cylinder : [tex] \sf{\pi \: {r}^{2} h}[/tex]
plug the values
⇒[tex] \sf{ \frac{22}{7} \times {3.5}^{2} \times 6}[/tex]
Evaluate the power
⇒[tex] \sf{ \frac{22}{7} \times 12.25 \times 6}[/tex]
Calculate
⇒[tex] \sf{231 \: {cm}^{ 3} }[/tex]
Hope I helped!
Best regards!!
Answer:
The answer is 231 cm^3
Step-by-step explanation:
This is a volume question so we will bring out the question comment first:
Diameter= 7 cm
Height =6 cm
We have to change the diameter to radius so we will do: the diameter which is 7 divided by two which will be 3.5.
We can now start proper.
Formula of volume=pile r square h
22/7 or 3.14 times the radius raised to power 2 times the height=
22/7 x 3.5^2 x 6=
22/7 x 12.25 x 6=
231 cm³
Hope it helps.

divide 5kg in the ratio 13:7
Answer:
1.75 kg
Step-by-step explanation:
13/20 of 5 = 13/20 x 5= 3.25 kg
and, 7/20 of 5 = 7/20 x 5=1.75 kg
so, divide, 5 kg in ration of 13:7 is:
3.25 kg : 1.75 kg
Answer:
3.25 Kg : 1.75 Kg
Step-by-step explanation:
Sum the parts of the ratio, 13 + 7 = 20 parts
Divide the amount by 20 to find the value of one part of the ratio.
5 Kg ÷ 20 = 0.25 Kg ← value of 1 part of the ratio, thus
13 parts = 13 × 0.25 =3.25 Kg
7 parts = 7 × 0.25 = 1.75 Kg
Find the value of $B - A$ if the graph of $Ax + By = 3$ passes through the point $(-7,2),$ and is parallel to the graph of $x + 3y = -5.$
Answer:
-6
Step-by-step explanation:
The parallel line can be written using the same x- and y-coefficients, but with a different constant:
x +3y = constant
For the line to go through the given point, the constant must be ...
(-7) +3(2) = constant
-1 = constant
In order for the constant to be +3 instead of -1, the entire equation must be multiplied by -3:
-3x -9y = 3 ⇒ A = -3, B = -9
Then the expression B-A is ...
B -A = (-9) -(-3) = -6
The value of B - A is -6.

Write the equation of the line that has the indicated slope and contains the indicated point. Express the final equation in standard form. m = 1/2 , (3, 4)
Answer:
x - 2y = - 2
Step-by-step explanation:
Given the following :
1/2 , (3, 4),
The equation of a line :
y = mx + c
m = slope ; c = gradient
m = 1/2
c = (y1 - x1) / 2
c = (4 - 3) / 2 = 1/2
Hence, y = 1/2x + 1/2
In standard form:
Ax + By = C
A and B integer Coefficient of x and y respectively
y = 1/2x + 1/2
1/2x - y = - 1/2
Multiply both sides by 2
x - 2y = - 2
Hence, standard form of the equation is :
x - 2y = - 2
Emily was digging for gold. She dug a total of 40 feet deep into the ground. She dug 17% every minute. How far had she dug after 3 minutes?
Answer:
91 feet or 51
Step-by-step explanation:
17x 3= 51
51 + 40(what she dug before)
or it's just 51
Answer:
60.4 ft deep
Step-by-step explanation:
17% = .17
40 * .17 = 6.8 per hour
6.8 * 3 = 20.4
20.4 + 40 = 60.4 ft deep
An airplane takes 8 hours to travel a distance of 5824 kilometers against the wind. The return trip takes 7 hours with the wind. What is the rate of the plane in still air and what is the rate of the wind?
Answer:
Speed of plane in still air = 780 km/h
Speed of air = 52 km/hr
Step-by-step explanation:
Let the speed of plane in still air = u km/h
Let the speed of air = v km/h
Against the air, the resultant speed = (u-v) km/hr
With the air, the resultant speed = (u+v) km/hr
Formula for speed is given as:
[tex]Speed = \dfrac{Distance}{Time }[/tex]
Given that:
Distance = 5824 km
Time taken against the wind = 8 hours
Speed against the wind:
[tex]u-v = \dfrac{5824}{8} \\\Rightarrow u-v = 728 ...... (1)[/tex]
Time taken with the wind = 7 hours
Speed with the wind:
[tex]u+v = \dfrac{5824}{7} \\\Rightarrow u+v = 832 ...... (2)[/tex]
Adding (1) and (2):
[tex]2u=1560\\\Rightarrow u = 780\ km/hr[/tex]
By equation (1):
[tex]780-v=728\\\Rightarrow v = 52\ km/hr[/tex]
Speed of plane in still air = 780 km/h
Speed of air = 52 km/hr

What is the sum of -2-(-17)
Answer: Hi!
Remember, when you're subtracting a negative, that's equal to adding a positive. So -2-(-17) is actually equal to -2 + 17!
-2 + 17 = 15
The expression -2-(-17) is equal to 15.

6x² + 5x-2x
I am trying to do combining like terms
Step-by-step explanation:
To combine like terms, we need to find similar numbers. 5x and -2x can be simplified because they both end with x. 6x^2 is different because it ends with x^2. So to simplify, we subtract 2x from 5x to get 3x, and we add 6x^2 to get our answer.
Answer: [tex]6x^2+3x[/tex]
Answer:
6x² +3x
Step-by-step explanation:
We are given the expression:
[tex]6x^2 + 5x-2x[/tex]
and asked to combine like terms. Let's analyze the terms.
6x² ⇒ has a variable, x²
5x ⇒ has a variable, x
2x ⇒ has a variable, x
Now, let's group the like terms, 5x and -2x.
[tex]6x^2+ (5x-2x)[/tex]
Next, combine the like terms. Subtract 2x from 5x.
[tex]6x^2+(3x)[/tex]
[tex]6x^2+3x[/tex]
The expression 6x² +5x-2x simplified is 6x² +3x
Is (-2,0) a solution of the graphed inequality
Answer: NO
