find the time in which a train of length 132 M will cross and electric post if the speed of the train be to 6.4 km /hour
Answer:
It will take the train 1.2375 minutes to pass the tunnel
Step-by-step explanation:
Mathematically, we know that ;
time = distance/ speed
The distance here is the length of the train which is 132 m ; we can convert this to km by dividing by 1000
We have this as 132/1000 = 0.132 km
So, we have the time as;
0.132 km/6.4 km/hr = 0.020625 hr
Mathematically, we know that 60 minutes make an hour;
so we have
0.020625 * 60 = 1.2375 minutes
ABC is a right angled triangle
AC=6cm
AB=20cm
Calculate length of BC
Give answer to 1 decimal place
Answer:
19.1cm
Step-by-step explanation:
AB=20
AC=6
BC=?
So,by Pythagoras Theorem:-
AC2=AB2+BC2
Therefore:-
AB2-AC2=BC2
400-36=BC2
√364=BC2
19.1=BC2
Answer:
19.1 cm
I don't have a picture so I hope this is what you mean/
Step-by-step explanation:
AB²-AC²=BC²
20²-6²=BC²
400-36=BC²
364=BC²
√364=√BC²
BC≈19.1

What is the total surface area of the square pyramid?
Answer:
D
Step-by-step explanation:
[tex]A_1 = a^2 = 14^2 = 196[/tex]
[tex]A_2 = 4(\frac{b * h}{2}) = 4(\frac{14 * 12}{2}) = 4(\frac{168}{2}) = 4 * 84 = 336[/tex]
[tex]SA = A_1 + A_2 = 196 + 336 = 532\ cm^2[/tex]
What is the slope of the line? 4x-1=3y+54x−1=3y+54, x, minus, 1, equals, 3, y, plus, 5 Choose 1 answer: Choose 1 answer: (Choice A) A \dfrac23 3 2 start fraction, 2, divided by, 3, end fraction (Choice B) B \dfrac34 4 3 start fraction, 3, divided by, 4, end fraction (Choice C) C \dfrac32 2 3 start fraction, 3, divided by, 2, end fraction (Choice D) D \dfrac43 3 4
Answer:
Slope of the line, m = 4/3
Step-by-step explanation:
Given;
4x - 1 = 3y + 5
Make y the subject
4x - 1 = 3y + 5
4x - 3y = 5 + 1
4x - 3y = 6
-3y = 6 - 4x
Divide both sides by -3
y = (6 - 4x) / -3
y = -2 + 4/3x
Slope intercept form is given by
y = mx + b
Where,
m = slope
y = - 2 + 4/3x
m = 4/3
Slope of the line, m = 4/3
Answer:
Above answer is INCORRECT.
The CORRECT answer is 2/3

Answer:
[tex]\angle LMK\sim \triangle KMJ \sim \triangle LKJ[/tex]
Step-by-step explanation:
In the right triangle shown, two right triangles are inscribed in a third right triangle, with all three triangles sharing an altitude. Thus, all three right triangles are similar.
The second portion asks to draw them so that their corresponding sides and angles have the same orientation. I can't demonstrate that here but here are some tips:
Draw them so that it is clear that they are similarMake sure that their corresponding sides match upWhen writing your similarity statement, the order of which you list the triangles' vertices should be maintained, e.g. [tex]\angle LMK\sim \triangle KMJ \sim \triangle LKJ[/tex]Here is an example of the drawing portion from the CK-12 Foundation:
Answer:
Solution given:
In triangle LMK and triangle LKJ
<LMK=<JMK[ being right angle]
<MLK=<JLK[common angle]
<MKL=<LJK[remaining angle]
so
∆MLK~ ∆MLJ[By A.A.A.axiom]
∆MLK is similar to ∆MLJ
A group of people were asked how many people live in their household. What percent of these people have exactly 2 people in their household?
Answer:
16%
Step-by-step explanation:
Given
[tex]\begin{array}{cccccc}{Size & {1} & {2} & {3} & {4} & {5} \ \\ {f} & {3} & {4} & {6} & {7} & {5} \ \end{array}[/tex]
Required
The percentage of household with 2 people
First, calculate the total frequency
[tex]Total = 3 + 4 +6+7+5[/tex]
[tex]Total = 25[/tex]
The frequency of household with 2 people is:
[tex]f(2) = 4[/tex]
So, the percentage is calculated as:
[tex]\% =\frac{f(2)}{Total} * 100\%[/tex]
[tex]\% =\frac{4}{25} * 100\%[/tex]
[tex]\% =\frac{400}{25}\%[/tex]
[tex]\% =16\%[/tex]

& A bowl made in the shape of a hemisphere has diameter of 12 centimeters. When the bowl is
completely filled with soup, its total weight is 658.74 grams. If the soup weighs 1.02 grams per
cubic centimeter, which of the following is closest to the weight of the empty bowl?
12 cm
(1) 197 grams
(2) 264 grams
(3) 452 grams
(4 461 grams
Answer:
3
Step-by-step explanation:
volume of a hemisphere = (2/3) x (n) x (r^3)
n = 3.14
r = radius = 12/2 = 6
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
(2/3) X (6^3) X 3.14 = 452.16 cm^3
1 cm = 1 gram
452.16g

Find the solution set of the inequality \qquad52- 3x < -14.52−3x<−14.52, minus, 3, x, is less than, minus, 14, point \qquad xxx
Answer:
x > 22
Step-by-step explanation:
Given the inequality;
52- 3x < -14
Subtract 52 from both sides
52 - 3x - 52 < -14 - 52
-3x < -14 - 52
-3x < -66
Divide both sides by -3
-3x/-3 < -66/-3
x > 22
Hence the required inequality is x > 22

Answer:
[tex]\small{\boxed{\tt{2 \sqrt{5} (13 + \sqrt{2} = 26 \sqrt{5} + 2 \sqrt{10} = 64.3}}}[/tex]
Step-by-step explanation:
Given : Expression
[tex]2 \sqrt{5} (13 + \sqrt{2} )[/tex]
To find : Simplify the expression
Solution :
Step 1 - Write the expression
[tex]2 \sqrt{5} (13 + \sqrt{2} )[/tex]
Step 2 - Apply distributive property,
[tex]a(b + c) = a × b + a \times c[/tex]
[tex] = 2 \sqrt{5} \times 13 + 2 \sqrt{5 } \times \sqrt{2} [/tex]
Step 3 - Apply square root property,
[tex] \sqrt{x} \times \sqrt{y} = \sqrt{xy} [/tex]
[tex] = 26 \sqrt{5} + 2 \sqrt{10} [/tex]
or to simplify more substitute the value of [tex] \sqrt{5} = 2.23[/tex] and [tex] \sqrt{10} = 3.16[/tex]
Simplification-
[tex] = 26(2.23) + 2(3.16)[/tex]
[tex]= 57.98 + 6.32[/tex]

Area = 36 [tex]in^{2}[/tex]
Only one number will make this missing length true.
Obviously it's a square so one number x one number will equal to 36 [tex]in^{2}[/tex]
6 x 6 = 36 [tex]in^{2}[/tex]
Answer:
The missing length of square is 6 in.
Step-by-step explanation:
Here we have given the area of square = 36 in ²
We need to find the missing length of square .
note :- missing length = side all side of square are equal.Using formula
Area of square = ( side ) ²
put the values
36 in² = ( side)²
Finding the square root of 36 in²
√36 in ² = side
6 in = side
Hence, the side of square is 6 in.

Answer:
18.9
Step-by-step explanation:
First, lets solve for the fractions. You can divide the fractions from the top, to their bottom (4 divided by 5, 3 divided by 5), in this case, you get 1.4. Now you have to rewrite the problem: 1.4+3.5x5. You solve it, and get 18.9.
Answer:
18.9

0<4(possible)
A map has a scale of 2 inches : 25 miles. Chandra uses the map to find the distance from the zoo to her house. The distance on the map is 5 inches. How many miles away is the zoo from Chandra’s house?
Step-by-step explanation:
Turn the ratio into a fraction
2in /25 mi
You want to have miles so you can flip the fraction and mutiply to cancel out the inches
(25mi / 2in) x 5in = (25 mi x 5in) / 2in
if a dog drinks 8 quart of water a day, how many gallons does the dog drink in 3 days
Answer:
6 gallons
Step-by-step explanation:
There are 4 quarts in gallons, so the dog drinks 2 gallons a day.
When we multiply 2 and 3, we would get 6.
So the dog drinks 6 gallons in 3 days (I don't know about you, but that's a lot of water)
---------------------------------------------------------------------------------------------------------------
Have a great summer :)
Answer:
The dog will drink 6 gallons.
Step-by-step explanation:
Every 8 quarts is 2 gallons.
Multiply 2 by 3, you'll get 6.
that's how much gallons a dog drinks in 3 days.

Plot the coordinates of the point:
(a) whose co-ordinate is -5 and which lies on y axis.
(b) Which lies on x and y-axis both.
(c) whose abscissa is 3 and which lies on x-axis in cartasian plance.
Answer:
First, a regular point is written as a coordinate pair (x, y).
If the point lies on the x-axis, then we have y = 0
if the point lies on the y-axis, then x = 0
And x is the abscissa, y is the ordinate.
The points will be graphed at the end.
a)
Ordinate = -5, then y = -5
and it ies on the y-axis, then x = 0
So this point is represented by A = (0, -5)
b)
Lies on the y-axis and in the x-axis, then x = 0 and y = 0, so the point is represented by B = (0, 0)
c)
The abscissa is 3, so x = 3, and the point lies on the x-axis, so y = 0
Then this point is represented by C = (3, 0)
The graph with the 3 points are:
