Answer:

A. The surface area of the cheese is 24·π in.² or 75.40 in.²

B. The surface area of the remaining cheese after the wedge is removed is about 72 in.²

2. The surface area decreased

Step-by-step explanation:

From the figure attached to a similar question, we have;

Radius, r of cheese = 3 in.

Height, h of the cheese = 1 in.

A. The surface area of the cheese is equal to the area of two circles, one on top and the other underneath added to the surface area of the sides which is equivalent to the surface area of a cylinder given by the relation

Surface area of the cheese = 2×π×r² + 2×π×r×h

∴ Surface area of the cheese = 2×π×3² + 2×π×3×1 = 24·π in.²

Surface area of the cheese = 24·π = 75.398 ≈ 75.40 in.² to the nearest 10th

B. The surface area of the remaining cheese after the wedge is removed is found by first subtracting the cut wedge from the total surface area as follow

Outer surface area of cut wedge = 24·π÷8 = 3·π

New outer surface area = Total surface area - Removed outer surface area

∴ New outer surface area = 24·π - 3·π = 21·π

New total surface area = New outer surface area + Area of newly exposed segment

Area of newly exposed segment = 3 × 1 × 2 = 6 in.²

∴ New total surface area = (21·π + 6) in.² = 71.9734 in.² ≈ 72 in.²

The surface area of the remaining cheese after the wedge is removed is about 72 in.²

2. The surface area decreased.

Answer:

A. The surface area of the cheese is 24·π in.² or 75.4 in.² B. The surface area of the remaining cheese after the wedge is removed is about 72 in.² 2. The surface area decreased

Step-by-step explanation:

Answer: 6

Step-by-step explanation:

Given Data:

Number of people = 6

Amount of Gold to be shared = 40lbs

Subtract 2/3 from your answer.

Therefore

If six people are to share 40lbs of gold evenly

= 40lbs / 6

Divide through by 2

= 20lbs / 3

= 20lbs / 3 - 2/3

= 18/3

= 6

Each person would get approximately 6lbs of gold

Answer:

1. Each individual gets [tex]6\frac{2}{3}lb[/tex] of gold

2. After subtracting by [tex]1\frac{2}{3}[/tex] , the result is 5

Step-by-step explanation:

Given

Size of Gold = 40 lbs

Number of people = 6

Required

1. Proportion of each individual

2. Subtract [tex]1\frac{2}{3}[/tex] from each proportion

1. Proportion of each individual

To calculate how many each individuals get (in other words, the proportion of each individual), we simply divide the total size of gold by the number of people

Mathematically,

[tex]Proportion = \frac{Total}{People}[/tex]

[tex]Proportion = \frac{40}{6}[/tex]

Reduce fraction to lowest term by dividing numerator and denominator by 2

[tex]Proportion = \frac{20}{3}[/tex]

Convert to mixed fraction

[tex]Proportion = 6\frac{2}{3}[/tex]

Hence each individual gets [tex]6\frac{2}{3}lb[/tex] of gold

2. Subtract [tex]1\frac{2}{3}[/tex] from each proportion

This is represented by

[tex]6\frac{2}{3} - 1\frac{2}{3}[/tex]

Convert both fractions to improper fractions

= [tex]\frac{20}{3} - \frac{5}{3}[/tex]

Find LCM of both fractions

= [tex]\frac{20 - 5}{3}[/tex]

Subtract

= [tex]\frac{15}{3}[/tex]

= 5

Hence, after subtracting by [tex]1\frac{2}{3}[/tex] , the result is 5

Answer:

10 ft

Step-by-step explanation:

area of trapezoid = (B + b)h/2

where B and b are the lengths of the bases, and h is the height.

A = (B + b)h/2

115 = (19 + 4)h/2

230 = 23h

23h = 230

h = 10

Answer: 10 ft

The height of the trapezoid with base lengths of 4 and 19 feet and an area of 115 square feet is 10 feet.

A trapezoid is a quadrilateral which is having a pair of opposite sides as parallel and the length of the parallel sides is not equal.

The area of a trapezoid is given as half of the product of the height(altitude) of the trapezoid and the sum of the length of the parallel sides.

[tex]\rm{ Area\ of\ trapezoid = \dfrac{1}{2} \times Height \times(Sum\ of\ parallel\ sides)[/tex]

The area of a trapezoid is given as half the product of the sum of the parallel sides and the height of the trapezoid.

The length of the parallel sides of the trapezoid is 4 and 19 feet, while the area of the trapezoid is 115 square feet. Therefore, the height of the trapezoid is,

115 ft² = 0.5 × (4 ft + 19 ft ) × height

115 ft² = 0.5 × 23 ft × height

height = (115 ft²)/ (0.5 × 23 ft)

height = 10 feet

Hence,  the height of the trapezoid is 10 feet.

Answer:

Step-by-step explanation:

The fidelity investment mutual funds is $10.92 per share.

The fund charges 2.5%.

So, if 2.5% is charged,

Then, 2.5% of the share is

2.5% of $10.92 = 2.5 / 100 × $10.92

2.5% of $10.92 = $0.273

Then, total offer price is 0.273 + 10.92

Therefore, total offer is $11.193

Final answer:

The offer price of the real estate income mutual fund from Fidelity Investments is $11.2135 per share.

Explanation:

The offer price of the real estate income mutual fund from Fidelity Investments can be calculated by adding the load to the selling price per share. In this case, the load is 2.5% of $10.94 per share. To find the load amount, multiply 2.5% by $10.94, which is equal to $0.2735. Then, add the load amount to the selling price per share: $10.94 + $0.2735 = $11.2135.

Answer:

61°

Step-by-step explanation:

∠SPQ is a straight line, so it equals to 180°.

∠SPR is 119° and since we're looking for ∠QPR, we subtract 119° from 180°.

180° - 119° = 61°, so ∠QPR = 61°

Answer:

61 degrees

Step-by-step explanation:

Because SPQ is said to be a straight line, we know that a straight line in this kind of equation is equal to 180 degress.

Since we already know the measure to one angle (119), we would need to find the difference between 180 and 119, meaning we'd have to subtract.

(180-119)

Then we would just get the sum, which in this case, is 61 degrees.

Answer:

The distance between opposite corners of the living room is 30ft

Step-by-step explanation:

This can be thought of as a right triangle and we want to know its hypotenuse

To calculate one side of a right triangle from the other 2 sides we have to use Pythagoras

h = hypotenuse

a = leg 1 = 18ft

b = leg 2 = 24ft

h² = a² + b²

we replace the known values

h² = (18ft)² + (24ft)²

h² = 324ft² + 576ft²

h² = 900ft²

h = √(900ft²)

h = 30ft

Answer:

The concentration is 12M

Step-by-step explanation:

In this question, we are asked to calculate the concentration of the alkali given the information in the question.

To answer this question correctly, the first thing to do is to write the complete chemical equation of the reaction of the acid and the alkali. We identify that LiOH is the alkali and HCl is the acid

LiOH + HCl ———-> LiCl + H2O

we can deduce that 1 mole of the acid used up a mole of the base.

Now, we use the titration formula;

CaVa/Na. = CbVb/Nb

since Na= Nb = 1 i.e number of moles , we can just write the formula to be

CaVa. = CbVb

Where Ca is the concentration of the acid which is 4M

Va is the volume of acid used which is 60mL

Cb is the concentration of the base which is ?

Vb is volume of base which is 20mL

Plugging these values, we have;

4 * 60 = Cb * 20

Cb = 240/20

Cb = 12M

The concentration of the base is thus 12M

The product of the real and complex number given is -10+40i

Step-by-step explanation:

The general form of a complex number is expressed as z = x+iy where

x is the real part and y is the imaginary part.

Given a complex and a real value as shown

z1 = −2+8i and z2 = 5+i0

Taking their product;

z1z2 = (−2+8i)(5+i0)

z1z2 = -10+0+40i+0

z1z2 = -10+40i

According to the product of the complex numbers, the resulting real part is -10 and the complex part is 40.

The representation on the complex plane is as shown in the attachment.

The complex number −2+8i has modulus of (1. 2√17)

When −2+8i is multiplied by 5, the modulus of the product is (2. 10√17)

Multiplying a complex number by a real number results in a scalar of the complex number. The quadrant location of the complex number and its product with (3. a positive real number) are the same.
