14 ft > [tex]4\frac{1}{2}[/tex] yards

Step-by-step explanation:

Given,

14 ft ____ 4 1/2 yd.

We will convert yards into feet to determine the inequality.

1 yard = 3 feet

[tex]4\frac{1}{2}[/tex] yards = [tex]3*4\frac{1}{2}[/tex]

[tex]4\frac{1}{2}[/tex] yards = [tex]3*\frac{9}{2}[/tex]

[tex]4\frac{1}{2}[/tex] yards = 3*4.5 = 13.5 feet

which is less than 14 feet, making 14 feet greater, therefore, we will use 'greater than' inequality.

Step-by-step explanation:

The length of rectangle will be 18 meters and width of rectangle will be 11 meters.

It is given that width of a rectangle is seven meters less than the length.

If perimeter of rectangle is 58 meters then find the value of length and width.

What are the area and perimeter of a rectangle ?

The area of rectangle is A = L × B and the perimeter is 2 ( L + B ) , where ; L = length and B = width.

Let's assume the length of the rectangle is x.

The width of the rectangle will be ;

= x - 7

Also ; the perimeter of triangle is given which is equal to 58 meters.

We know that ; the perimeter of triangle is given by ;

Perimeter = 2 × ( length + width )

So ;

58 = 2 [ x + (x - 7)]

58 = 2 ( 2x - 7 )

58 = 4x - 14

or

4x = 58 + 14

4x = 72

x = 72 ÷ 4

x = 18 meters

So ;

Length = 18 meters

and

Width = 18 -7 = 11 meters

Thus , the length of rectangle will be 18 meters and width of rectangle will be 11 meters.

Answer:

The area of the circle is 3,8550 mm

Step-by-step explanation:

Diameter    (d) = 70 mm

Radius             (r) = (70/2) mm = 35mm

Π                   = 22/7

Area of circle x       =   πr^2

                  =   22/7 x 35^2

                  =   22/7 x 1225

                  =   26,950/7

                  =   3,850 mm

Length of diameter is 2.86 cm

Solution:

Given that circumference of a circle is 8.97 cm

To find: length of diameter

We can use the formula for circumference of circle to find radius and then we can find diameter

The circumference of circle is given as:

[tex]C = 2 \pi r[/tex]

Where "r" is the radius of circle and [tex]\pi[/tex] is a constant equals to 3.14

Substituting c = 8.97 and [tex]\pi = 3.14[/tex]

[tex]8.97 = 2 \times 3.14 \times r\\\\8.97 = 6.28 \times r\\\\r = \frac{8.97}{6.28}\\\\r = 1.4283[/tex]

Thus radius of circle is 1.4283 cm

Finding diameter of circle

diameter = 2(radius)

diameter = 2(1.4283) = 2.8566

On rounding to two decimal point we get, 2.86

Thus length of diameter is 2.86 cm

To find the total weight in Robbie's backpack, the weights of the history textbook (2 5/6 pounds) and lunch (1 2/3 pounds) are added, resulting in a total of 4 1/2 pounds.

Explanation:

The question involves finding the total weight of items in Robbie's backpack: a history textbook and his lunch. The history textbook weighs 2 5/6 pounds and his lunch weighs 1 2/3 pounds.

To find the total weight, we first convert the mixed numbers into improper fractions for easier addition. The history textbook's weight as an improper fraction is (2×6)+5 = 17/6 pounds. The lunch's weight is (1×3)+2 = 5/3 pounds.

Adding these two fractions gives us:

   17/6 + 5/3 = 17/6 + 10/6 = 27/6 pounds

Since 27/6 simplifies to 4 1/2 pounds, the total weight in Robbie's backpack is 4 1/2 pounds.

Irene's list of factors for the number 88 is almost correct, but she forgot to include the number 1.

Irene wants to list the factors for 88 and she writes 2, 4, 8, 11, 22, 44, and 88. To verify if Irene is correct, we need to identify all of the numbers that can evenly divide 88 without leaving a remainder. Starting with the number 1, which is a factor of every number:

1 x 88 = 88, so 1 and 88 are factors.

2 x 44 = 88, so 2 and 44 are factors.

4 x 22 = 88, so 4 and 22 are factors.

8 x 11 = 88, so 8 and 11 are factors.

Since there are no other numbers between 1 and 88 that can multiply together to equal 88, the list that Irene wrote appears to be missing the number 1.

Therefore, Irene's list is almost correct, but for it to be complete, it should include the number 1. The full list of factors for the number 88 should be 1, 2, 4, 8, 11, 22, 44, 88.

4 tens 6 ones

Step-by-step explanation:

those are the only way

The number 46 can be expressed as 4 tens and 6 ones, representing the value 40 plus 6, utilizing the powers of ten place value system.

When expressing the number 46 in terms of tens and ones, we use the place value system which is based on powers of ten.

In this system, each place in the number represents a power of 10.

To represent 46 as tens and ones, we look for the highest power of ten that fits into the number without exceeding it.

In the case of 46, that value is 40, because 4 tens (4 x 10) equal 40, and there are 6 ones left over.

Therefore, we can say that 46 consists of 4 tens and 6 ones. This can be shown visually as:

Area of curved surface,

= 2πrh

= 2π(3)(12)

= 72π units²

Hence,

Surface area = 18π + 72π = 90π units²

The solution is, 90π units² is its surface area.

Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

C

Step-by-step explanation:

The diagonal of the square creates 2 right triangles with the diagonal as the hypotenuse.

Using Pythagoras' identity in either of the right triangles.

The square on the hypotenuse is equal to the sum of the squares of the other 2 sides.

Let x be the side of the square, then

x² + x² = 40², that is

2x² = 1600 ( divide both sides by 2 )

x² = 800 ( take the square root of both sides )

x = [tex]\sqrt{800}[/tex]

  = [tex]\sqrt{100(8)}[/tex]

=  = 10[tex]\sqrt{8}[/tex]

  = 10 × 2[tex]\sqrt{2}[/tex] = 20[tex]\sqrt{2}[/tex] → C

Answer:  [tex]m=0[/tex]

The slope can be calculated with this formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Notice that the formula shows the change in "y" for a unit change in "x"  on the line.

In order to solve this exercise, it is important to remember that:

1. If a line is increasing, then its slope is positive.

2. If a line is decreasing, then its slope is negative.

3. If the line is horizontal, its slope is zero.

4. If the line is vertical, it has no slope.

Therefore, since the given line that passes through the point [tex](3,-4)[/tex], is horizontal, its slope is:

Answer:

.19 cent per egg

Step-by-step explanation:

15*12=180

34.20/180= .19

The unit cost per egg is $0.60 when a case of eggs costs $34.20.

The unit cost per egg is $0.60.

To find the cost per egg when a case contains 15 dozen eggs costing $34.20, you first calculate the cost per dozen by dividing the total cost by the number of dozens (15). Then, you divide the cost per dozen by 12 to find the cost per egg. In this case, $34.20 divided by 15 gives $2.28 cost per dozen. Finally, $2.28 divided by 12 equals $0.60, so each egg costs $0.60.

You need to factor the numerator and denominator...

(2x^2+4x-2x-4)/(2x^2-2x-2x+2)

(2x(x+2)-2(x+2))/(2x(x-1)-2(x-1))

Answer:

1. The percent commission earned is 3%.

2. The loan period is 3.29 years.

Step-by-step explanation:

1. Salesman has $65,100 in sales. He earned $1,953 in commission.

Let the percent commission earn be x%

Therefore, x% of the sales equals $1,953

[tex]\frac{x}{100} of  $65,100 = $1,953[/tex]

[tex]\frac{x}{100}  * 65100 = 1953\\\frac{65100x}{100} = 1953[/tex]

We cross multiply

[tex]\frac{65100x}{100}  = 1953\\65100x = 1953 * 100\\65100x = 195300[/tex]

Divide both side by the coefficient of 'x' (65100)

[tex]\frac{65100x}{65100} =  \frac{195300}{65100} \\x = 3[/tex]

Therefore, the percent commission earned is 3%

2. Interest (I) = $299  Principal (P) = $1300   Rate (R) = 7%

The formula for finding interest is given as: [tex]I = \frac{PRT}{100}[/tex]

Therefore, substituting into the formula, we have:

[tex]299 = \frac{1300 * 7 * T}{100}[/tex]

We are finding the time it takes the loan to earn an interest of $299

[tex]299 = \frac{1300 * 7 * T}{100} \\299 = \frac{9100T}{100}[/tex]

We cross-multiply:

[tex]299 * 100 = 9100T\\29900 = 9100T[/tex]

Divide both side by the coefficient of T (9100)

[tex]\frac{29900}{9100}  = \frac{9100T}{9100}\\T = 3.29[/tex]

Therefore, the time taken for the loan to earn such interest is approximately 3.29 years

Then, the option 41.9 is incorrect because is less than 42 and x is greater-or-equal-to 42; option 44 inches is incorrect because it is equal to 44 and the equality sign is not included; option 44.1 inches is greater than 44 and x is less than 44; and option 42 inches is correct  because x is greater-than-or-equal to 42, that is, the equal sign is included.

Answer:

64,000 ounces

Step-by-step explanation:

1 ton = 32,000 ounces

2 tons x 32,000 ounces (which is equal to one ton)

=64,000 ounces

2 tons = 64,000 ounces

A 2-ton rhinoceros weighs 64,000 ounces, which is calculated by converting tons to pounds and then pounds to ounces.

The weight of a rhinoceros weighing 2 tons can be calculated in ounces by first converting the weight to pounds. As we know from previous examples, 1 ton = 2,000 pounds. So, a 2-ton rhinoceros weighs 2 × 2,000 = 4,000 pounds. Now, to convert pounds to ounces, we use the conversion factor that 1 pound = 16 ounces. Therefore, a 2-ton rhinoceros weighs 4,000 × 16 = 64,000 ounces.
