Answer:

multiply all of them then add all of them then divide by the lowest number

12:1 is the scale factor

3.5 ÷ 3.5 = 1 and 142 ÷ 3.5 =123.5 so 42:123.5 ratio simplified is 12:1

Looking at the question, to find the scale factor we are going to divide 42 by 3.5 which is 12. To check our work we will do 1 times 3.5 which is 42.

Why is it not 147:1? Well, scale factoring means that in two similar geometric figures, the scale factor is the ratio of their corresponding sides, dividing the two corresponding lengths of the sides will gives the ratio

Answer:

Given:

Area of the sector (A) = 104π/9 square inches

Central angle (θ) = 65 degrees

The formula for the area of a sector of a circle is:

A = (θ/360) * π * r^2

We can rearrange this formula to solve for the radius (r):

r^2 = (A * 360) / (θ * π)

Plugging in the given values:

r^2 = (104π/9 * 360) / (65 * π)

r^2 = (104 * 40) / 9

r^2 = 4160 / 9

r^2 ≈ 462.22

Taking the square root of both sides:

r ≈ √462.22

r ≈ 21.49

Therefore, the radius of the circle is approximately 21.49 inches.

Answer:

Lateral area of the pyramid = 120 square units

Step-by-step explanation:

In the figure attached,

A pyramid has been given with square base with edges of 12 units and perpendicular height as 8 units.

Lateral area of a pyramid = Area of the lateral sides

Area of one lateral side = \(\frac{1}{2}(\text{Base})(\text{Lateral height})\)

                                       = \(\frac{1}{2}(\frac{b}{2})(\sqrt{(\frac{b}{2})^2+h^2})\)  [Since l = \(\sqrt{r^{2}+h^{2}}\)]

                                       = \(\frac{1}{2}(6)(\sqrt{6^2+8^2})\)

                                       = \(3\sqrt{100}\)

                                       = 30 units²

Now lateral area of the pyramid = 4 × 30 = 120 square units

Answer: 240 units^2

Step-by-step explanation:

LA= 1/2 Pl

P= perimeter of base

l= lateral height

l= 8^2 + (12/2)^2 = 10^2

P= 12 x 4 = 48

48 x 10 = 480

480/2 = 240

Now,

Two angles are 45.

This means,

The side opposite to angle 45 are equal.

So,

a = c

And,

a = 7.5 yd

Now,

Applying the Pythagorean theorem.

b² = a² + c²

b² = 7.5² + 7.5²

Taking the values provided into consideration, the correct answer is option D, the absolute difference being 144,000 and the relative difference being 59,3%.

The absolute difference between the number of people whose first language is English and the number of people whose first language is Spanish is calculated by subtraction:

243,000 - 99,000 = 144,000

To find the relative difference as a percentage, we divide the absolute difference by the compared value (English speakers) and then multiply by 100:

(144,000 / 243,000) x 100 = 59.3%

Answer:

Step-by-step explanation:

8/21 of the lawn still needs to be mowed.

To compare fractions, we need a common denominator. The least common multiple of 7 and 3 is 21.

Miss Lianto's fraction: (2/7) x (3/3) = 6/21

Son's fraction: (1/3) x (7/7) = 7/21

To calculate how much of the lawn still needs to be mowed, we can subtract the combined fractions mowed from the total:

Combined fractions mowed: 6/21 + 7/21 = 13/21

So, Remaining fraction: 1 - 13/21 = 8/21

Therefore, 8/21 of the lawn still needs to be mowed.

Answer:

x = 6 ft

Step-by-step explanation:

Total area of the given polygon = Area of triangle 1 + Area of rectangle 2 + Area of triangle 3

Area of triangle 1 = Area of triangle 3 = \(\frac{1}{2}(\text{Base})(\text{Height})\)

                                                              = \(\frac{1}{2}(x)(8)\)

Rounding the number 347,500 to the nearest 1000, 10000, and 100,000 will give us 348,000, 3,50,000, and 3,00,000 respectively.

To approach this answer we must first know how to read a number starting from the rightmost corner i.e units. A common rule to keep in mind is when the number is equal to 5 or more, round it off to the next consecutive number if it is less than 5 round it off to the previous number.

We look at the hundredth digit, which is 5 in this case. Since it's equal to 5 we round the thousandth digit to 8 to get 348,000.

We look at the thousandth digit, which is 7 in this case. Since it is greater than 5, we will round the ten thousandth digit to 50 to get  350,000

We look at the ten thousandth digit, which is 4 in this case. Since 4 is less than 5 we can round down the hundred thousandth digits to 300 to get 300,000.

Therefore rounding the number 347,500 to the nearest 1000, 10000, and 100,000 will give us 348,000, 3,50,000, and 3,00,000 respectively.

Using the property of exponents as

When multiplying two exponential expressions with the same base, you can add the exponents. This can be expressed as follows:

aᵇ x aⁿ= aᵇ⁺ⁿ

When dividing two exponential expressions with the same base, you can subtract the exponents. This can be expressed as follows:

aᵇ / aⁿ= aᵇ⁻ⁿ

So, cd³ c⁻⁵ x d⁻²

= c¹⁻⁵ x d³⁻²

The area of the shaded region, with a frame of 3 units wide, is 264 square units. The inner rectangle is 6x4 units, and the outer rectangle is 18x16 units.

To solve the given problem, we have to find the area of the shaded region if the frame is 3 units wide. If the frame is 3 units wide, then the dimensions of the inner rectangle (the shaded region) will be (12 - 6) × (10 - 6) which simplifies to 6 × 4.

Therefore, we can say that the inner rectangle has a length of 6 units and a width of 4 units.The dimensions of the outer rectangle are (12 + 3 + 3) × (10 + 3 + 3) which simplifies to 18 × 16. Therefore, we can say that the outer rectangle has a length of 18 units and a width of 16 units.

The area of the shaded region can be obtained by subtracting the area of the inner rectangle from the area of the outer rectangle. Therefore, the Area of the outer rectangle = length × width= 18 × 16 = 288 square units

Area of the inner rectangle = length × width= 6 × 4 = 24 square units

Area of the shaded region = Area of the outer rectangle - Area of the inner rectangle = 288 - 24= 264 square units

Therefore, the area of the shaded region is 264 square units.
