Answer:
57/200
Step-by-step explanation:
285/1000 The fraction is not reduced to lowest terms. We can reduce this fraction to lowest
terms by dividing both the numerator and denominator by 5.
Why divide by 5? 5 is the Greatest Common Divisor (GCD)
or Greatest Common Factor (GCF) of the numbers 285 and 1000.
So, this fraction reduced to lowest terms is
57/200
So your final answer is: 0.285 can be written as the fraction 57/200
−0.258 written as a fraction in its simplest form is [tex]-\frac{129}{500}[/tex]
To write a given decimal as a fraction in its simplest form,
We will first express the decimal as a fraction and then reduce it to its lowest form.
The given decimal is −0.258
−0.258 written in fraction is [tex]-\frac{258}{1000}[/tex]
Now, we will reduce [tex]-\frac{258}{1000}[/tex] to its lowest form
First, we will divide both the numerator and denominator by 2 (Since 2 is a common factor)
We get
[tex]-\frac{258}{1000} = -\frac{258 \div 2}{1000 \div 2} = -\frac{129}{500}[/tex]
Since the fraction cannot be reduced further, then −0.258 as a fraction in its simplest form is [tex]-\frac{129}{500}[/tex]
Hence, −0.258 written as a fraction in its simplest form is [tex]-\frac{129}{500}[/tex]

What is the third quartile of this data set?
20, 21, 24, 25, 28, 29, 35, 37, 42, 43, 44
Answer:
You should get 42
Step-by-step explanation:
In the picture I sent you, to find quartile 1 and 3 and the median use the order you have and slash out from the left and the right, if you don't get 2 numbers that you have to add and divide by 2 for the median you have to make lines outside of the middle number and slash on each side to get quartile 1 and quartile 3. Quartile 2 is the median.
The third quartile of the data set is, 42.
What is Ascending order?The numbers arrange in order to least to greatest number is called Ascending order.
Now, For the third quartile of the data set, we first need to find the median, which is the second quartile.
Hence, We can ordering the data set in ascending order:
20, 21, 24, 25, 28, 29, 35, 37, 42, 43, 44
Here, The median is the middle number or the average of the two middle numbers if the data set has an even number of values.
In this case, we have 11 values, so the median is the 6th value, which is 29.
And, we need to find the third quartile, which is the median of the upper half of the data set. The upper half of the data set includes the values:
35, 37, 42, 43, 44
The median of these values is the third quartile.
Hence, take the middle value or the average of the two middle values if there is an even number of values in the upper half.
In this case, there are 5 values in the upper half,
Hence, the median is the 3rd value,
⇒ 42.
Therefore, the third quartile of the data set is, 42.

Gwen has a £5 note and a £2 coin. A litre of cola costs £1.25. Gwen buys as many litre bottles of cola as she can. How much money will she have left over?
Gwen can buy 5 bottles of cola with her £7 and will have £0.75 left over.
Explanation:Gwen has in total £7 (£5 note + £2 coin). A litre of cola costs £1.25. To find out how many bottles of cola Gwen can buy, we need to divide the total amount Gwen has by the cost of one bottle of cola.
Divide the total amount of money (£7) by the cost of one litre of cola (£1.25).£7 ÷ £1.25 = 5.6. Gwen can buy 5 bottles because she cannot buy a fraction of a bottle.Multiply the number of bottles she can buy (5) by the cost per bottle (£1.25) to find out the total cost. 5 × £1.25 = £6.25.Subtract the total cost of the cola (£6.25) from the total amount of money Gwen has (£7). £7 - £6.25 = £0.75.
Therefore, Gwen will have £0.75 left over after buying as many bottles of cola as she can.

sqrt(x^2) = sqrt(112)
x = sqrt(16*7)
x = 4 sqrt(7)
The circumference of a great circle of a sphere is 44π. Find the Surface Area of the sphere.
Answer:
1936 π square units
Step-by-step explanation:
Given the information:
The circumference of a great circle of a sphere is 44π.
As we know the formula used to find a circle's circumference is:
C = 2πr , where r is the radius of the circle
In this situation, we know C = 44π
<=> 2πr = 44π
<=> r = 22 units
Hence, the Surface Area of the sphere
S.A = 4π[tex]r^{2}[/tex]
= 4π[tex]22^{2}[/tex]
= 1936 π square units

The distance (d) between two points (x₁, y₁) and (x₂, y₂) can be given as:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Therefore distance between AB = [tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}=\sqrt{(-1-4)^2+(3-5)^2}=\sqrt{25+4}=5.385[/tex]
distance between BC = [tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}=\sqrt{(-3-(-1))^2+(-4-3)^2}=\sqrt{4+49}=7.28[/tex]
distance between CA = [tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}=\sqrt{(4-(-3))^2+(5-(-4))^2}=\sqrt{49+81}=11.4[/tex]
The total distance = AB + BC + AC = 5.385 + 7.28 + 11.4 = 24.065 miles

Sample response: Start by calculating the volume of the original prism. The area of the base, B, is 4(6) = 24 m2. Multiply that by the height to get the volume: 24(10) = 240 m3. Now, if you double all of the dimensions, you would have a rectangular prism with a base that is 8 m by 12 m and a height of 20 m. The area of the base, B, is 8(12) = 96 m2. Multiply that by the height to get the volume: 96(20) = 1,920 m3. To compare, look at the ratio of the original prism to the new prism: 96/1,920 = 1/8. The volume increases by 8 times the original volume.
Check all that you included in your response.

Answer: x² + 4x - 32
Step-by-step explanation: So to multiply these two binomials together, let's use the F.O.I.L. method.
Remember, F.O.I.L. stands for First, Outter, Inner, Last.
This is because we start with the product of the first terms which is x², then we add the product of the outer terms which is 8x, then we add the middle terms which is -4x, and then we add the product of the last terms which is -32.
So we have x² + 8x + -4x + -32.
Combining the like terms 8x + -4x, our final answer is x² + 4x - 32.

find the surface area of the square pyramid if the slant height is 13mm and the base length is 11mm
a) 264mm squared
b) 286mm squared
c) 335.5mm squared
d) 407mm squared
To find the surface area of a square pyramid, you need to calculate the lateral area and the area of the base. The lateral area can be found using the formula (1/2) × perimeter of the base × slant height. The base area is equal to the side length squared. To find the total surface area, you add the lateral area and the base area.
Explanation:Surface Area of Square PyramidTo find the surface area of a square pyramid, we need to calculate the lateral area and the area of the base.
Lateral Area
The lateral area of a square pyramid can be found using the formula:
Lateral Area = (1/2) × perimeter of the base × slant height
In this case, the slant height is given as 13mm and the base length is given as 11mm, so we have:
Lateral Area = (1/2) × 4 × 11mm × 13mm = 286mm2
Base Area
The base of the square pyramid is a square with side length 11mm. Therefore, the area of the base is:
Base Area = side length × side length = 11mm × 11mm = 121mm2
Total Surface Area
To find the total surface area, we add the lateral area and the base area:
Total Surface Area = Lateral Area + Base Area = 286mm2 + 121mm2 = 407mm2
Therefore, the surface area of the square pyramid is 407mm2.

Y varies inversely with x, when y is 48 when x is 1/3 .which equation represents this situation?
a) Y=16/x
b) Y=16x
c) Y=144x
d) Y= 144/x
Answer:
A
Step-by-step explanation:
Given that y varies inversely with x then the equation relating them is
y = [tex]\frac{k}{x}[/tex]
To find k use the condition y = 48 when x = [tex]\frac{1}{3}[/tex], thus
k = yx = 48 × [tex]\frac{1}{3}[/tex] = 16
y = [tex]\frac{16}{x}[/tex] ← equation of variation
Colin & Brian share a lottery win of £2100 in the ratio 4 : 1. Colin then shares his part between himself, his wife & their son in the ratio 2 : 5 : 3. How much more does his wife get over their son?
Answer:
His wife gets $336 more than his son.
Step-by-step explanation:
Colin and Brian:
Ratio of 4:1.
So Colin gets [tex]\frac{4}{4+1} = \frac{4}{5}[/tex] of the prize.
[tex]\frac{4*2100}{5} = 1680[/tex]
Colin got $1680. Dividing between himself, his wife and their son:
Ratio of 2:5:3.
So Colin gets [tex]\frac{2}{2+3+5} = \frac{2}{10}[/tex], his wife gets [tex]\frac{5}{2+3+5} = \frac{5}{10}[/tex] and his son gets [tex]\frac{3}{2+3+5} = \frac{3}{10}[/tex]
Wife:
[tex]\frac{5*1680}{10} = 840[/tex]
His wife got $840.
Son:
[tex]\frac{3*1680}{10} = 504[/tex]
His son got $504.
How much more does his wife get over their son?
840 - 504 = 336
His wife gets $336 more than his son.
A projectile with an initial velocity of 48 feet per second is launched from a building 190 feet tall. The path of the projectile is modeled using the equation h(t) = –16t2 + 48t + 190. What is the maximum height of the projectile? 82 feet 190 feet 226 feet 250 feet
Answer:
226 feet
Step-by-step explanation:
The maximum height of the projectile is 226 feet
How to calculate the maximum height of an object?Given the equation of the height modelled as h(t) = –16t^2 + 48t + 190
The ball reaches the maximum height at the point where v = dh/dt = 0
dh/dt = -32t + 48
32t = 48
t = 1.5s
Get the maximum height;
h(1.5) = –16(1.5)^2 + 48(1.5) + 190
h(1.5) = -36 + 72 + 190
h(1.5) = 226 feet
Hence the maximum height of the projectile is 226 feet

Answer:
The area of the sector is 3pi/2
Step-by-step explanation:
A sector is that part of a circle bounded by 2 radii and an arc
The circle has an area of 9 pi with a central angle of 60 degrees.
Now the area of the sector is pretty much straight forward to calculate. Since it is a circle, the total angle we have is 360.
Now the sector subtends an angle of 60 degrees at the centre. What this means is that the sector is exactly 1/6 of the circle. meaning that cutting the circle into 6 slices will give the sector.
Thus, the area of the sector is one-sixth the area of the circle.
The area of the sector is thus 1/6 * 9pi = 9pi/6 = 3pi/2 or 3/2 pi

Work out the surface area of this solid prism.
The surface area of the solid rectangular prism is 408 square meters.
To find the surface area of a solid rectangular prism, you can use the formula:
Surface Area = 2lw + 2lh + 2wh
Where:
l = length
w = width
h = height
In your case, the dimensions of the prism are:
Length (l) = 9 meters
Width (w) = 10 meters
Height (h) = 6 meters
Now, plug these values into the formula:
Surface Area = 2(9m)(10m) + 2(9m)(6m) + 2(10m)(6m)
Surface Area = 180m^2 + 108m^2 + 120m^2
Now, add these areas together:
Surface Area = 180m^2 + 108m^2 + 120m^2 = 408m^2
So, the surface area of the solid rectangular prism is 408 square meters.
