Rajan is given half a chocolate to divide amongst 4 people including himself what fraction of the whole chocolate is he left with?
Answer: If Rajan has [tex]\frac{1}{2}[/tex] of a chocolate bar, then he has to divide it 4.
[tex]\frac{1}{2}[/tex] ÷ 4 = [tex]\frac{1}{8}[/tex]
Step-by-step explanation:
[tex]\frac{1}{2}[/tex] ÷ 4
[tex]\frac{1}{2}[/tex] × [tex]\frac{1}{4}[/tex]
Multiply the numerators and denominators and you will get: [tex]\frac{1}{8}[/tex]

A supervisor finds the mean number of miles that the employees in a department live from work. he finds x overbar = 29 and s = 3.6. which mileage is within a z-score of 1.5? 21 miles 24 miles 36 miles 41 miles
A supervisor finds the mean number of miles that the employees in a department live from work is 24. Then the correct option is B.
What is a z-score?The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.
The z-score is given as
[tex]z = \dfrac{x-\mu }{s}\\[/tex]
x = 29
s = 3.6
z = 1.5
Then the mean will be
[tex]1.5 = \dfrac{29 - \mu }{3.6}\\\\\mu = 29 - 5.4\\\\\mu = 23.6 \approx 24[/tex]

The length of a picture frame is 7 inches more than the width. For what values of x is the perimeter of the picture frame greater than 150 inches.
Answer:
x > 34
Step-by-step explanation:
Let x be the width of the picture frame
It then follows that the length = x + 7
Therefore, our inequality is:
[tex]2(x+7) +2x > 150\\2x+14+2x > 150\\4x > 136\\x > 34[/tex]
For all values of x greater than 34 the perimeter is greater than 150 inches.
Answer:
x is greater than 34 inches.
Step-by-step explanation:
Let x = width, then the length = x+7 inches.
Perimeter = 2(W + L) = 2(x + x + 7) = 4x + 14 , so:
4x + 14 > 150
4x > 150 - 14
4x > 136
x > 34.

(The rooms are both rectangular) Carly's bedroom is 15.3 ft. long and 8.7 ft. wide. Carter's bedroom is 14.4 ft. long and 9.6 ft. wide. Which bedroom will be the most expensive to cover with carpet? Explain your steps for figuring out the area of the floor for each bedroom and determining your answer. Make sure to Show your math steps as well. ~ 100 POINTS AND ILL GIVE YOU BRAINLIEST IF YOU ANSWER CORRECTLY AND 5 SENTENCES NEEDED
If Carly's bedroom is 15.3ft long and 8.7 ft long then it is necessary to multiply them because you need to find the area of the room so 15.3*8.7= 133.11. We have to do the same for Carter's room so we multiply 14.4 and 9.6 to find the area of the room which is 138.24.
Now that we have both the areas we can compare which room is bigger. Carly's room is 133.11 ft in total and Carter's room is 138.24 ft in total. So it is clear that Carter's room is going to be more expensive to cover with carpet since Carter's room is bigger than Carly's.

I need help now!!!!
help me need the correct answer!!!!!!!!!!!!
Step-by-step explanation:
so, the garden seems to be rectangular.
it has a length.
and width = length - 2
I assume the fence should go all around the rectangular garden.
that means it has to cover 2 lengths and 2 widths.
fence = 2×length + 2×(length - 2) =
= 2×length + 2×length - 4 = 4×length - 4 =
= 4×(length - 1)
length = 7.5 m
so, he will need
4×(7.5 - 1) = 4×6.5 = 26 meter of fencing.

Answer:
c= 30
Step-by-step explanation:
To find the value of c, start by forming an equation using the ∠ sum of ∆ property.
c° +60° +90°= 180° (∠ sum of ∆)
Simplify:
c° + 150°= 180°
c°= 180° -150°
c°= 30°
c= 30
Notes:
The sum of the angles in a triangle is 180°, which is abbreviated as '∠ sum of ∆'. The angle indicated by a square is called a right angle, and has a value of 90°.it would be really helpful if i knew the answer step by step thank you

The surface area, the lateral area and the volume are, respectively:
S = 100 mi², L = 200 mi², V = 500 mi³S ≈ 201.062 cm², L ≈ 508.938 cm², V ≈ 1809.558 cm³S = 139.5 km², L = 180 km², V = 558 km³S = 6 km², L = 108 km², V = 54 km³How to determine the volume, the lateral area and the surface area of each solid
The volume is a measure of the space occupied by the solid, the lateral area is the measure of the area occupied by lateral faces of the solid and the surface area is the area occupied by the cross section of the solid. Please notice that the volume of each prism is equal to the product of the surface area and the height of the solid and the lateral area is the sum of the areas of the lateral faces.
In this exercise we must follow these steps to obtain the required results:
Calculate the surface area.Calculate the lateral area.Calculate the volume.Lastly, we proceed to make the corresponding calculations:
Surface area - Figure 1S = (10 mi)² = 100 mi²
Lateral area - Figure 1L = 4 · (10 mi) · (5 mi) = 200 mi²
Volume - Figure 1V = S · h = (100 mi²) · (5 mi) = 500 mi³
Surface area - Figure 2S = 0.25 π · (16 cm)² ≈ 201.062 cm²
Lateral area - Figure 2L = π · (18 cm) · (9 cm) ≈ 508.938 cm²
Volume - Figure 2V = S · h = (201.062 cm²) · (9 cm) ≈ 1809.558 cm³
Surface area - Figure 3S = 0.5 · (5) · (9 km) · (6.2 km) = 139.5 km²
Lateral area - Figure 3L = (5) · (4 km) · (9 km) = 180 km²
Volume - Figure 3V = S · h = (139.5 km²) · (4 km) = 558 km³
Surface area - Figure 4S = 0.5 · (3 km) · (4 km) = 6 km²
Lateral area - Figure 4L = (9 km) · (3 km) + (9 km) · (4 km) + (9 km) · (5 km) = 108 km²
Volume - Figure 4V = S · h = (6 km²) · (9 km) = 54 km³

If John is driving 55 miles per hour down
195, how many feet per minute is he
traveling?
The feet per minute that John is travelling down 195 is 4840 feet per minute.
How many feet per minute is he traveling?Average speed is the total distance travelled per time. It is determined by dividing total distance travelled by total time.
In order to convert 55 miles per hour to feet per minute, we have to know the unit of conversion :
1 mile = 5280 feet
1 hour = 60 minutes
55 x (5280 / 60) = 4840 feet per minute
