Answer: 12.1 ft
Step-by-step explanation:
A ramp represents a right-angled triangle so Pythagorean formula can be used to find the diagonal length which will also be the hypotenuse.
c² = a² + b²
Where:
c = hypotenuse
a = base
b = Height
c² = 11² + 5²
c² = 121 + 25
c² = 146
c = √146
c = 12.1 ft

Answer:
x=1/2, y=4
Step-by-step explanation:
Double both sides of the top equation:
4x+6y=26
Now subtract boths sides of the second one from the first one:
(4x+6y) - (4x-y) = 26 - (-2)
7y = 28
so y = 4
4x-y=-2 so 4x-4=-2
4x=2
x=1/2

When a plot is sold for Rs. 18,700, the owner loses 15%. At what price must that plot be sold in order to gain 15%?
Answer: Rs. 25,300
Step-by-step explanation:
First find the original price of the plot:
Assume this price is x:
x * ( 1 - 15%) = 18,700
0.85x = 18,700
x = 18,700/0.85
x = Rs. 22,000
To make a gain of 15%, sell at:
= 22,000 * (1 + 15%)
= 22,000 * 1.15
= Rs. 25,300

Find the area of the trapezoid. A drawing of a trapezoid with length of two parallel sides equal to a mixed fraction of one and a half centimeters and three and a half centimeters. The altitude of the trapezoid is 4 centimeters.
Answer:
[tex]10cm^2[/tex]
Step-by-step explanation:
We are given that
Two parallel sides of trapezoid are
[tex]a=1\frac{1}{2}cm=\frac{3}{2}=1.5cm[/tex]
[tex]b=3\frac{1}{2}=3+0.5=3.5 cm[/tex]
Height of trapezoid, h=4 cm
We have to find the area of the trapezoid.
We know that
Area of trapezoid=[tex]\frac{1}{2}(a+b)h[/tex]
Where a and b are two parallel sides
h=Height of trapezoid
Using the formula
Area of trapezoid=[tex]\frac{1}{2}(1.5+3.5)\times 2[/tex]
Area of trapezoid=[tex]10cm^2[/tex]
The shoreline of Great Bear Lake is approximately 2719 km (not counting islands). If a map is drawn with a scale of 3 cm:100 km, how long would the shoreline be on the map?
Answer:
81.57 cm
Step-by-step explanation:
Given that :
Scale :
3cm : 100km
This means ; 3cm on the map represents an actual length of 100km
Actual length of shoreline = 2719 km
The length of the shoreline on the map will be :
(2719 km / 100 km) * 3cm
27.19 * 3cm
= 81.57 cm
Answer:
81.57 cm

Solve the following expression when
x=4 and y=10
6x - 3x + 5 - y
Answer:
7
Step-by-step explanation:
We can simplify this because 6x - 3x is equal to 3x, so we get that the expression is 3x - y + 5. Next, we can plug in our values. 3 * 4 - 10 + 5 is equal to 12 - 10 + 5, which is 2 + 5, which is 7.
The value of the expression 6x - 3x + 5 - y at x = 4 and y = 10 is 7.
What is substitution?Substitution in mathematics is when we replace some specific numerical values to variables according to our wants or given in the problem.
Given, An expression 6x - 3x + 5 - y.
Now, The value of the expression at x = 4 and y = 10 can be obtained by replacing the numerical values of x and y.
Therefore, 6x - 3x + 5 - y at x = 4 and y = 10 is,
6(4) - 3(4) + 5 - 10.
= 24 - 12 + 5 - 10.
= 12 - 5.
= 7.

Patty rolls a six-sided number die 120 times. How many times should she expect to roll a
prime number?
Answer is 60 times.
Explanation:
Prime numbers in a die are 2, 3 and 5 (i.e. 3 numbers)
Total outcomes can be 1, 2, 3, 4, 5 and 6 (i.e. 6 numbers)
Probability
= Number of preferred outcomes/ Total number of outcomes
= 3/6
= 1/2
= 0.5
Probability of getting a prime number while throwing the dice 120 times
= 0.5 × 120
= 60 times

In ΔDEF, d = 6.4 inches, e = 7.8 inches and ∠F=33°. Find the length of f, to the nearest 10th of an inch.
9514 1404 393
Answer:
4.3 in
Step-by-step explanation:
The Law of Cosines is applicable when you have two sides and the angle between them. The third side satisfies ...
f² = d² + e² -2de·cos(F)
f² = 6.4² + 7.8² -2·6.4·7.8·cos(33°) ≈ 18.0671
f ≈ √18.0671 ≈ 4.2505
The length of f is about 4.3 inches.

Answer:
13.7ft^2
Step-by-step explanation:
Area for triangle:
The formula for the area of a triangle in this scenario is area=(b*h)/2
The base length is 3.6ft and the height is 4.8ft. We can now substitute these values into the equation. So:
area=(3.6*4.8)/2
area=8.64ft^2 for the triangle
Area for semi-circle:
The formula for the area of a circle is area=pi*r^2. To find the area of the semi-circle, we can half the area of the circle at the end.
The question says to use 3.14 for the value of pi.
The diameter is given as 3.6ft, so to find the radius, we simply divide the diameter by 2; so 3.6/2=1.8ft for the radius
Now, we can just substitute these values into the equation above. So:
area=3.14*(1.8)^2
area=3.14*3.24
area=10.1736ft^2 (DO NOT ROUND THIS ANSWER!!).
However, this area is for the COMPLETE circle. We want the area for the semicircle shown above. Therefore, divide the circle area by 2. So:
10.1736/2=5.0868ft^2 for the semicircle.
Total area of shape
Now we have the area of the two separate shapes, we can simply add them together. So:
8.64ft^2 + 5.0868ft^2 = 13.7268ft^2 altogether (unrounded)
Now, finally we must round to 1/10, or to 1 decimal place. Therefore, the final value for the area would be 13.7ft^2.
Hope this helped!!
