Given:
1 cm in the plan is equal to 2 meters in real life
Length of corridor in plan = 9 cm
To find:
Actual length of corridor
Steps:
Since we know that 1 cm in plan = 2 meters
So,
9 cm = 2 * 9
length of corridor = 2 * 9
Length of corridor = 18 meters
Therefore, the length of the corridor is 18 meters

Step-by-step explanation:
Answer:
(x^2 + 2x) cm^2
Step-by-step explanation:
Area of trapezium = 1/2 (a+b)h
= 1/2 [(x+3)+(x+1)] (x)
=1/2 (2x+4)(x)
= 1/2 (2x^2 + 4x)

Answer: 3 miles.
Step-by-step explanation:
Since we are given the information that Ms. Wilson walked ¾miles each day. To calculate the total distance that Ms. Wilson will walk for 4 days, we have to multiply the distance walked each day by 4.
This will be:
= ¾miles × 4
= 3 miles
Therefore, Wilson walked a distance of 3 miles for the 4 days.

What is the definition of mathematic
Answer:
Mathematics :Mathematics is the science that deals with the logic of shape, quantity and arrangement. Math is all around us, in everything we do. It is the building block for everything in our daily lives, including mobile devices, architecture (ancient and modern), art, money, engineering, and even sports.
Since the beginning of recorded history, mathematic discovery has been at the forefront of every civilized society, and in use in even the most primitive of cultures. The needs of math arose based on the wants of society. The more complex a society, the more complex the mathematical needs. Primitive tribes needed little more than the ability to count, but also relied on math to calculate the position of the sun and the physics of hunting.

Olivia wants to spend at most $259 on
video games.
If each video game cost $64, what is the
maximum number of games Olivia can
buy?
4 is the maximum number of video games Olivia can buy
Answer:
4 games
Step-by-step explanation:
Find the maximum number of games she bought by dividing 259 by 64:
259/64
= 4.04
Since we can only have a whole number of games, we have to round this down.
4.04
= 4
So, the maximum number of games she can buy is 4.

Megan can paint three times faster than Julie. Together they can paint in 2 hours. How long would it take each of them alone? Which equation can be used to solve this?
(1/x)+(1/3x)=2
2(1/x)+2(1/3x)=1
(1/x)+(1/3x)=1
4(1/x)+2(1/3x)=1
Answer:
The second one
2(1/x) + 2(1/3x) = 1
Step-by-step explanation:
1/x + 1/(3x) = 1/2
multiply both sides by 2
2(1/x) + 2(1/(3x) = 1

PLEASE HELP!! Find mCFD
180°
276
307
53°
Answer:
307°
Step-by-step explanation:
CF is a diameter of the circle. so, any arc connecting C and F has an arc angle of 180° (half-circle).
so, we need to add the arc angle FD.
we know the arc angle ED = 79°.
so, what is left to add is the arc angle FE.
the arc angle FE is the same as BC.
and the arc angle BC is the supplementary angle (means together they have 180°) to 132° :
BC = 180 - 132 = 48°
therefore,
the arc angle CFD = 180 + 48 + 79 = 307°
A rectangular prism has the following dimensions.
length: 18 inches
width: 1 foot
height: 14 inches
If all the dimensions of this prism are tripled, what will be the surface area of the new figure?
7,632 in. 2
11,448 in. 2
3,816 in. 2
27,216 in. 2
Answer: 11,448
Step-by-step explanation: I’m not sure if this is correct but I saw this answer a few times on another website similar to Brainly, and I thought it could help you all, if it’s correct.
The surface area of new rectangular prism is 11448 square inches.
What is a rectangular prism?A rectangular prism can be defined as a 3-dimensional solid shape which has six faces that are rectangles. It has 8 vertices, 6 faces, and 12 edges in which all the pairs of opposite faces are congruent.
For the given situation,
Length of the rectangular prism = 18 inches
Width of the rectangular prism = 1 foot = 12 inches
Height of the rectangular prism = 14 inches
All the dimensions are tripled, so multiply all the dimensions by 3.
Length, l = [tex](18)(3)[/tex]
⇒ [tex]l=54[/tex]
Width, w = [tex](12)(3)[/tex]
⇒ [tex]36[/tex]
Height, h = [tex](14)(3)[/tex]
⇒ [tex]42[/tex]
The formula of surface area of rectangular prism is
[tex]A=2(lw+wh+lh)[/tex]
⇒ [tex]2((54)(36)+(36)(42)+(42)(54))[/tex]
⇒ [tex]2(1944+1512+2268)[/tex]
⇒ [tex]2(5724)[/tex]
⇒ [tex]11448[/tex]
Hence we can conclude that the surface area of new rectangular prism is 11448 square inches.

Find the value of c such that lim f(x) exists.
f(x) = 4 – 0.5x. x < 2
√x+c. x > 2
Answer:
c=7
Step-by-step explanation:
because the limit exists and this is a piecewise function, we can assume that f(2) is a removable discontinuity and that both equations should be the same.
we can equal them to each other, plug in 2 for x and solve for c.
root(x + c) = 4 - .5x
root(2 + c) = 4 - .5(2)
root(2 + c) = 3
2 + c = 9
c = 7

Random samples of female and male UVA undergraduates are asked to estimate the number of alcoholic drinks that each consumes on a typical weekend. The data is below:
Females (Population 1): 2, 2, 2, 5, 5, 5, 1, 2, 3, 5
Males (Population 2): 5, 4, 5, 7, 4, 7, 5, 4, 4, 8
Give a 97.6% confidence interval for the difference between mean female and male drink consumption. (Assume that the population variances are equal.)
Confidence Interval =
Answer:
Confidence Interval =-3.4085 ,+0.7915
Step-by-step explanation:
The confidence interval can be determined by
(x1`- x2`) ± 1.955 √s1²/n1 + s2²/n2
The mean and the standard deviations can be calculated using the calculator.
The mean x1`= ∑x/ n= 2+ 2+ 2+ 5+ 5+ 5+ 1+2+ 3+ 5/10
= 32/10= 3.2
Standard deviation = s1`= 1.536
The mean x2`= ∑x/ n= 5 +4 +5+ 7+ 4+ 7+ 5+ 4+ 4+ 8/10
= 53/10= 5.3
Standard Deviation = s2= 1.4177=1.42
Putting the values
(x1`- x2`) ± 1.955 √s1²/n1 + s2²/n2
(3.2-5.3 ) ± 1.955 √1.54²/10 +1.42²/10
-2.1 ± 1.955 √ 2.37/10 +2.11/10
-2.1 ± 1.3085
