Answer:
There are £61.50 in 992 rubles
Step-by-step explanation:
Here, we shall be doing some currency conversions.
Now,
£31 = 500 rubles
Then;
£x = 992 rubles
To get c, what we do is simply cross multiply
£x * 500 rubles = £31 * 992 rubles
£x = (£31 * 992 rubles)/500 rubles
£x = £61.504
which is £61.50 to two decimal places

Another candle has a volume of 75 cubic inches and a height of 6 inches. What is the radius, in inches, of this candle. Round your answer to the nearest inch
Given Information:
Volume of candle = V = 75 in³
Height of candle = h = 6 in
Required Information:
Radius of candle = r = ?
Answer:
Radius of candle = r = 2 in
Step-by-step explanation:
Recall that the volume of a cylindrical shape is given by
[tex]V = \pi \times r^{2} \times h[/tex]
Where V is the volume, r is the radius and h is the height
Re-arrange the above equation for radius
[tex]r^{2} = \frac{V}{\pi \times h} \\\\r = \sqrt{\frac{V}{\pi \times h}}[/tex]
Now substitute the given values into the above equation
[tex]r = \sqrt{\frac{75}{\pi \times 6}}\\\\r = 1.99 \: in[/tex]
Rounding to the nearest inch
[tex]r = 2 \: in[/tex]
Therefore, the radius of this candle is 2 inches.

Given ΔADC and ΔAEB, What is AE?
Answer:
AE = 43.2 units
Step-by-step explanation:
As per the given question image, it can be seen that in the [tex]\triangle ADC \text { and }\triangle AEB :[/tex]
1. [tex]\angle B = \angle C = 90^\circ[/tex]
2. [tex]\angle A[/tex] is common to both the triangles.
3. Two angles are common, so the third angle [tex]\angle E[/tex] is also equal to [tex]\angle D[/tex].
All the three angles in the [tex]\triangle ADC \text { and }\triangle AEB[/tex] are equal to each other, hence the triangles are similar.
As per the property of similar triangles, the ratio of their sides will be equal.
AB : AC = AE : AD
AC = 88 units
BC = 55 units
AB = AC - AB = 33 units
Let side AE = [tex]x[/tex] units
Side AD = AE + ED
So, AD = [tex]x + 72[/tex]
Using the ratio:
[tex]\dfrac{AB}{AC} = \dfrac{AE}{AD}\\\Rightarrow \dfrac{33}{55} = \dfrac{x}{x+72}\\\Rightarrow 55x = 33 \times 72\\\Rightarrow x = \dfrac{3\times 72}{5}\\\Rightarrow x = 43.2\ units[/tex]
So, AE = 43.2 units

Find the remainder when p(x)= x^5 + x^4 + x^3 + x^2 + 2x + 2 is divided by q(x) = x + 1
Answer:
0
Step-by-step explanation:
Given a polynomial p(x) divided by (x + h), then the remainder is
p(- h)
Here divisor is (x + 1), so evaluate p(- 1) for remainder
p(- 1) = [tex](-1)^{5}[/tex] + [tex](-1)^{4}[/tex] + (- 1)³ + (- 1)² + 2(- 1) + 2
= - 1 + 1 - 1 + 1 - 2 + 2
= 0
This means that (x + 1) is a factor of p(x)

You can compute the slope of a line by using the slope ___
You can compute the slope of a line by using the slope formula. This is given by:
slope,m=(change in y-axis)/(change in x-axis)
=(Δ y-axis)/(Δ x-axis)
Given the points (x1,y1) and (x,y) from a linear graph, then:
slope m will be:
m=(y-y1)/(x-x1)
You can compute the slope of a line by using the slope formula.
A man 2 m high observes the angle of elevation to the top of a building to be 71° and the angle of depression to the bottom of the building to be 26°. How tall is the building?
Answer:
The building is 13.91 m tall
Step-by-step explanation:
The parameters given are;
Angle of elevation to the top of the building = 71°
Angle of depression to the bottom of the building = 26°
Height of the man = 2 m
Therefore, the sight of the man, the man's height, and the distance of the man from the building forms a triangle where:
The hypotenuse side = The sight of the man to the bottom of the building
Hence;
In ΔABC, A being at the eye level or head level of the man, B at the foot and C at the bottom of the building
∴ ∠A + Angle of depression to the bottom of the building = 90°
∠A = 90° - 26° = 64°
∠B = 90° and ∠C = 26° (Sum of angles in a triangle)
[tex]Tan(C) = \frac{AB}{BC}[/tex]
Distance of the man from the building = BC
[tex]Tan(26) = \frac{2}{BC}[/tex]
[tex]BC= \frac{2}{ Tan(26) } = 4.1 \, m[/tex]
Given that the angle of elevation to the top of the building = 71°, we have;
ΔAET
Where:
A is at the head level of the man,
E is the point on the building directing facing the man and
T is the top of the building
Hence AE = BC and ∡TAE = 71°
TE + AB= The height of the building
[tex]Tan(TAE) = \dfrac{TE}{AE}\\\\Tan(71) = \dfrac{TE}{4.1}[/tex]
∴ TE = tan(71°) × 4.1 = 11.91 m
Hence the height of the building = 11.91 + 2 = 13.91 m.

Given circle B, what is its diameter if its area is 56 square units?
Answer:
Diameter of the circle is 8.4 units
Step-by-step explanation:
To find the diameter of a circle with area of 56 square units, we will follow the steps below:
write the formula for calculating the area of a circle
area of a circle = πr²
from the question area= 56 units .
π is a constant which is ≈ 3.14
we can now proceed to substitute the values into the formula and solve for r
area of a circle = πr²
56 = 3.14×r²
divide both-side of the equation by 3.14
17.83 = r²
take the square root of both-side
√17.83 = √r²
4.2 =r
r= 4.2 units
but diameter = 2 r
diameter = 2×4.2
diameter = 8.4 units
Diameter of the circle is 8.4 units

About 180,000 people live in a 5-mile radius of a city's town hall. Find the population density in people per square mile. Round your answer to the nearest whole number.
Answer:
2291
Step-by-step explanation:
Given: Radius of a city's town hall is equal to 5-mile and about 180,000 people live in a city's town hall
To find: population density per square mile
Solution:
Population density refers to the number of people per unit of area.
Let r denotes radius of the town hall = 5 miles
Area of the town hall = [tex]\pi r^2=\pi (5)^2=25\,\pi[/tex] square miles
Population density per square mile = Population of a city's town hall/area of the town hall = 2290.9 [tex]\approx 2291[/tex]

How many gallons of paint will you need to paint a bedroom that is 10 ft by 14 ft with walls that are 7 1/2 ft high? The walls will need two coats to cover the old paint.
How many gallons of paint are needed to paint the ceiling of the same room in the last question, one coat of paint will suffice.
you have two walls that are 10 by 7.5 so 75 feet ^2 in area each
you have another two walls that are 14 by 7.5 so 105 feet^ 2 each
so all of that together is 360 feet^2 to cover for one coating, so you have 720 feet^2 to cover for 2 coats on the walls. so take that and divide it by the area that one gallon would cover, then round up giving you how many gallons you would have to buy
for the ceiling you do the same, the area is 140 and you only need one coat
Jordan is putting a fence around a garden that is shaped like a half circle and rectangle
Answer:
92 ft
Step-by-step explanation:
Assume the garden has the shape shown below.
The length of fencing equals the distance around three sides of the rectangle plus that around the semicircle.
1. Around the rectangle
Distance = 28 ft + 14 ft + 28 ft = 70 ft
2. Around the semicircle
For a circle.
C = 2πr
For the semicircle,
½C =½(2πr) = πr
D = 14 ft, so
r = 7 ft
[tex]\text{Distance} = \dfrac{22}{7} \times \text{7 ft} = \text{22 ft}[/tex]
3. Total distance
Distance = 70 ft + 22 ft = 92 ft
Jordan will need 92 ft of fencing.

Four circles or diameter d cm are arranged in such a way that they touch each other (as shown below). A square is formed by joining the centres of the four circles.
What is the area of the shaded part?
A) d2(1-π)
B) d2(4-π)
C) d2/4-πd2/4
D) d2-πd2/4
Answer:
D. d^2 - πd^2/4.
Step-by-step explanation:
The sides of the square are equal to the diameter of the circles so the area of the square = d^2.
The shaded area = area of the square - 4 * the area of a quarter circle
= area of the square - area of 1 circle
= d^2 - π r^2
r = d/2 so
Area of the shaded part = d^2 - π (d/2)^2
= d^2 - π (d^2/4)
