She has 1 61/152 pounds of apples left

Fractions are represented as numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing

In order to find how many pounds of apples she has left, subtract the apple she sold from the apple she begins with. That is:

Apple left = 35 1/2 - (35 1/2 * 1/2) - (35 1/2 *4/19) - (35 1/2 * 1/4 )

Apple left = 1 61/152

Answer:

A

Step-by-step explanation:

the area (A) of a circle is calculated as

A = πr² ( r is the radius )

given diameter = 14 then r = 14 ÷ 2 = 7

A = π × 7² = 49π m²

Answer:

49π

Step-by-step explanation:

area of circle=pie*radius²

and radius=diameter/2

therefore

r=14/2

=7m

Area =π*7²

Area=49π

The decimals are less than 0.03.

Answer:

600 cm²

Step-by-step explanation:

let x = length of a side of the cube

all sides are equal in a cube

Volume = x³ = 1000 cm³

x = ∛1000 = 10 cm

Area of 1 side = 10cm x 10cm = 100 cm²

There are 6 equal sides in a cube

SA = 6(100) =  600 cm²

As sets A, B, and C are subsets of the universal set U, the value of A’ ∪ B’ U C'  = {f}.

Demorgan's law can be utilised in set theory and boolean algebra to make mathematical formulations simpler. Let's say that the universal set U has two subsets, A and B. A' is A's complement, and B' is set B's complement.

Given that, (An B)' UC'.

Using the De Morgan's law we have:

(A ∩ B)’ = A’ ∪ B’.

Substituting this in (An B)' UC'. we have:

A’ ∪ B’ U C'

A' = {f, p, x, y}

B' = {f, g, h, p}

C' = {f, g, x, z}

A’ ∪ B’ U C'  = {f}

As sets A, B, and C are subsets of the universal set U, the value of A’ ∪ B’ U C'  = {f}.

The dimensions that will maximize the enclosed area are 125 meters by 250 meters

Represent the dimensions with x and y

So, we have the following equations

Perimeter = 4x + 2y = 1000

Area = 2xy

So, we have

2x + y = 500

This gives

y = 500 - 2x

So, we have

Area = 2x(500 - 2x)

Expand

Area = 1000x - 4x^2

Differentiate and set to 0

1000 - 8x = 0

So, we have

8x = 1000

Divide

x = 125

Recall that

y = 500 - 2x

y = 500 - 2 * 125

y = 250

Hence, the dimension is 125 by 250

9 miles for every ½ hour and 6 miles for every 20 minutes can be considered equivalent because they represent the same speed, just measured in different units.

To see this, we can convert the units to a common unit, such as miles per hour.

First, let's convert the 6 miles in 20 minutes to miles per hour:

[tex] \frac{6}{20} \times 60[/tex]= 18 miles/hour

Next, let's compare this speed to the 9 miles per ½ hour:

[tex] \frac{9}{ \frac{1}{2} } = \frac{9}{ \frac{1}{2} } \times \frac{1}{ \frac{1}{2} } = 18[/tex]

Since both speeds are equal to 18 miles per hour, we can conclude that they are equivalent. This means that the missing values are also equivalent.

The requried area of 3 of the pieces is 231 square feet. Option B is correct.

The area of a circle is the amount of space enclosed by the circle in a two-dimensional plane. It is given by the formula:

A = πr²

where "A" is the area of the circle, "r" is the radius of the circle, and "π" (pi) is a mathematical constant with an approximate value of 3.14159.

Here,
The area of a full circle with a radius of 14 feet is given by:

A = πr²

A = (22/7) × (14)²

A = (22/7) × 196

A = 616 square feet (rounded to the nearest whole number)

If the circle is cut into 8 equal pieces, each piece will have an area of:

616 ÷ 8 = 77 square feet

Therefore, 3 pieces will have an area of 3 × 77 = 231 square feet.

Thus, the requried area of 3 of the pieces is 231 square feet. Option B is correct.

Answer:

Step-by-step explanation:

Step 1: Subtract 63 from both sides.

7w+63−63≥150−63

7w≥87

Step 2: Divide both sides by 7.

7w/7  ≥  87/7

w ≥ 87/7

Evaluating the piecewise function we will get:

f(-1) = -13

f(0) =-8

f(2)  = 10

Here we have a piecewise function and we want to evaluate it on different values of x.

When x = -1, we need to use the first part, because -1 < 0.

f(-1) = 9*-1 - 4 = -13

when x  = 0, we need to use the second part, because 0 ≥ 0.

f(0) = 9*0 - 8 = -8

When x = 2 we also use the second part:

f(2) = 9*2 - 8

f(2) = 18 - 8 = 10

Answer:

Step-by-step explanation:

The lateral surface area of the pyramid can be found using the formula for the area of an equilateral triangle:

A = (s^2 * √3) / 4

where s is the length of one side of the equilateral triangle base.

For this pyramid, s = 50 feet

A = (50^2 * √3) / 4 = (2500 * √3) / 4 = 1250 * √3 ≈ 2129.28 ft^2

The total surface area of the pyramid can be found by adding the area of the base to the area of the lateral surface:

A = base area + lateral surface area

A = (side length^2 * √3) / 4 + (3 * triangle area)

A = (50^2 * √3) / 4 + (3 * (50^2 * √3) / 4)

A = 2500 * √3 + 3750 * √3 ≈ 5884.28 ft^2

To paint 75% of the pyramid, the painter needs to paint 75% * 5884.28 ft^2 = 4413.71 ft^2

Since the painter can paint 100 ft^2 in 18 minutes, he can paint 4413.71 ft^2 in 4413.71 / 100 * 18 minutes ≈ 786.96667 minutes

Rounding to the nearest tenth, the painter will take 786.967 minutes to paint 75% of the pyramid, which is approximately 13.1 hours.

The expressions that can be used to find the area of the shaded portion of the circle are 9²·π  - (2 · 13.5π ) and 2/3 · 9²·π

Since the whole circle has a radius of 9 inches. The area of the whole circle will be 9²·π square inches (Remember: Area of circle = πr²)

Also, the area of a single section of the circle is equal to 13.5π square inches.

We can get the area of the shaded portion (blue ones) by subtracting the area of the unshaded portion (white ones) from the area of the whole circle. That is:

9²·π  - (2 * 13.5π )

Notice that we have 2 unshaded (whites)

Also, there 4 shaded portions out of the whole 6. We can write:

area of shaded portions = 4/6  ·  9²·π = 2/3 · 9²·π

Thus, the expressions are is 9²·π  - (2 · 13.5π ) and 2/3 · 9²·π

Step-by-step explanation:

Answer:

1. The unit price for a doll is three dollars. The unit price for a purse is six dollars.

2. One doll costs three. One purse costs six.

3. Polly spends $24 on the 2 dolls and 3 purses.

Step-by-step explanation:

Doing some calculations, 1 doll costs three dollars and 1 purse costs six dollars.

5 x 3 + 6 = 21

7 x 3 + 1  = 27

If Polly buys 2 dolls and 3 purses, that means she spends six dollars on the dolls and eighteen dollars on the purses.

(2 x 3) + (3 x 6) = $24

Polly spends $24 on 2 dolls and 3 purses.

Angle geometry is a branch of mathematics that deals with the study of angles and their properties in two-dimensional figures such as circles, triangles, and polygons.

In the diagram, since vertically opposite angles are equal. Thus, we can say:

∠UTW =  ∠VTZ

90 - 52 = (12x - 10)°

38 = 12x - 10

12x = 38 + 10
