Step-by-step explanation

the common difference is -30

Final answer:

The sequence -38, -68, -98, -128,... is an arithmetic sequence because the common difference between consecutive terms is consistent, which is -30.

Explanation:

The student has asked whether the sequence -38, -68, -98, -128,... is arithmetic. To determine if a sequence is arithmetic, we need to check if the difference between any two consecutive terms (also known as the common difference) is the same.

Let's calculate the difference between the first two terms:

-68 - (-38) = -68 + 38 = -30

Now, let's calculate the difference between the second and the third terms:

-98 - (-68) = -98 + 68 = -30

Similarly, the difference between the third and the fourth terms is:

-128 - (-98) = -128 + 98 = -30

Since the common difference is the same (-30) for all consecutive terms mentioned, the sequence is indeed an arithmetic sequence.

Answer:

63 and 72

Step-by-step explanation:

Sum the parts of the ratio, 7 + 8 = 15 parts

Divide the sum by 15 to find the value of one part of the ratio

135 ÷ 15 = 9 ← value of 1 part of the ratio, thus

7 parts = 7 × 9 = 63

8 parts = 8 × 9 = 72

The numbers are 63 and 72

Answer:

123.9125

Step-by-step explanation:

The total amount of rainfall in Lakeview in 5.75 years is approximately 123.9125 inches. The correct answer is option C.

Lakeview gets 21.55 inches of rain per year on average.

To find the total amount of rainfall in Lakeview in 5.75 years, we can multiply the average yearly rainfall by the number of years.

Average yearly rainfall: 21.55 inches

Total rainfall in 5.75 years: 21.55 inches/year * 5.75 years

Calculating the result:

= 21.55 x 5.75

≈ 123.9125

Therefore, the total amount of rainfall in Lakeview in 5.75 years is approximately 123.9125 inches.

The correct answer is option C.

Answer:

b = 10

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )

Here h = 3x + 15 and A = 15x + 75, thus

[tex]\frac{1}{2}[/tex] × b × (3x + 15) = 15x + 75

Multiply both sides by 2 to clear the fraction

b(3x + 15) = 30x + 150

Divide both sides by (3x + 15)

b = [tex]\frac{30x+150}{3x+15}[/tex] ← factor numerator and denominator

  = [tex]\frac{30(x + 5)}{3(x+5)}[/tex] ← cancel the factor (x + 5) on numerator/denominator

  = [tex]\frac{30}{3}[/tex]

  = 10

Answer:

b = 10ft

Step-by-step explanation:

Area = ½ × base × height

15x + 75 = ½ × base × (3x + 15)

30x + 150 = base × (3x + 15)

10(3x + 15) = base × (3x + 15)

base = 10

The total length of wall is 160 inches

Solution:

Given that,

[tex]Length\ of\ each\ brick = \frac{2}{3}\ foot[/tex]

1 feet = 12 inches

Therefore,

[tex]Length\ of\ each\ brick = \frac{2}{3} \times 12\ inches = 8\ inches[/tex]

There are 20 bricks lined up end to end to make the wall

To find: Total length of wall in inches

[tex]Total\ length\ of\ wall = \text{length of each brick } \times \text{ total number of bricks}[/tex]

Thus we get,

[tex]Total\ length\ of\ wall = 8 \times 20\\\\Total\ length\ of\ wall = 160\ inches[/tex]

Thus total length of wall is 160 inches

In expanded form, 57,000 equals 50,000 + 7,000 therefore, number 60 and 4 are NOT one of the numbers that Kim wrote.

The expanded form of a number is the division of a number into place values, such as ones, tens, hundreds, thousands, ten thousand, and so on.

The number represented by the sum of each digit multiplied by its place value is known as its expanded form. When you write a number in expanded form, you write the value of each digit and then add them together to find the sum.

The number 1,24 has the following values, for example: it is in the thousands place, the value of one is written as 1,00. thus it is in the hundreds place, the value of 2 is written as 20.

Therefore,

Expanded Form of 57,000

57,000 =  50,000 + 7,000.

Hence, In expanded form, 57,000 equals 50,000 + 7,000.

Answer:

Step-by-step explanation:

Considering the given expressions

As we know that

Now, considering the expression

Here, the first term (monomial) i.e. [tex]7x^4\:[/tex] has the highest exponent of the variable. Here, the highest exponent is 4.

As the degree of the polynomial is said to be the highest degree of any of the terms.

Therefore, the degree of  [tex]7x^4\:+\:5x^2\:+\:x\:-\:9[/tex]  is 4.

The polynomial  [tex]7x^4\:+\:5x^2\:+\:x\:-\:9[/tex] can also be called a quadrinomial as it has four terms.

Also considering the second expression

This expression is not a polynomial.

For an expression to be a polynomial, it must must have to carry

Therefore, the expression [tex]7x^6\:-\:4x^3\:+\:1/x[/tex] is not a polynomial as the term      [tex]\frac{1}{x}[/tex] is not a polynomial as the the variable x is in the denominator.

Answer:

The per hour income of Siobhan is $9.31 per hour.

Step-by-step explanation:

Working in a grocery store James makes $7.00 per hour. Priya's hourly income is 40% more than James, and Siobhan's  hourly income is 5% less than Priya.

Therefore, using formula of percentage, the per hour income of Priya will be

[tex]7.00(1 + \frac{40}{100}) = 7 \times 1.4 = 9.8[/tex] dollars per hour.

Again, the per hour income of Siobhan is [tex]9.8(1 - \frac{5}{100}) = 9.8 \times 0.95 = 9.31[/tex] dollars per hour. (Answer)

Question:

The image of the question is attached below.

Answer:

Volume of the bench = 528 cubic inches

Solution:

Side of the cube = 4 inch

Volume of a cube = side × side × side

                              = 4 inch × 4 inch × 4 inch

Volume of a cube = 64 cubic inches

Volume of 2 cubes = 2 × 64 cubic inches

Volume of 2 cubes = 128 cubic inches

Length of the prism = 25 inch

Breadth of the prism = 4 inch

Height of the prism = 8 – 4 = 4 inch

Volume of the rectangular prism = length × breadth × height

                                                       = 25 inch × 4 inch × 4 inch

Volume of the rectangular prism = 400 cubic inches

Volume of the bench = volume of 2 cube + volume of the rectangular prism

                                    = 128 cubic inches + 400 cubic inches

Volume of the bench = 528 cubic inches

Hence volume of the bench is 528 cubic inches.

Thus, the units of measurement for the composite function s(W(h)) is bracelets over week.

Answer:

130°

Step-by-step explanation:

A hexagon's angels should be 720°.

so we need to substract the outer angels to find the interior angels.

180-75=105

180-38=142

180-42=138

180-65=115

180-90=90

then we add them up with x and equal it to 720

105+142+138+115+90+x=720

720-590=x

x=130

a=130

Answer:

a = 130°

Step-by-step explanation:

The interior angle of a polygon is calculated as

180° - exterior angle, thus

180° - 75° = 105°

180° - 42° = 138°

180° - 65° = 115°

180° - 90° = 90°

180° - 38° = 142°

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 6, thus

sum = 180° × 4 = 720°

Sum the interior angles and equate to 720

105 + 138 + 115 + 90 + 142 + a = 720, that is

590 + a = 720 ( subtract 590 from both sides )

a = 130

Answer:
