Answer:

Yes, 2,509 is less than 2,590

Step-by-step explanation:

When comparing 2509 to 2590, you first look at the first number on the left. In our case it is 2, then you look at the second number, which is 5, then you look at the third number which is 0 and 9, since the 9 is bigger that makes 2590 bigger than 2509, or 2509 less than 2590

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.

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.

Answer:

HCF of 112 and 46 = 2

Step-by-step explanation:

HCF/GCD/GCF all mean the same. They are the highest common factor of two or more numbers.

Step 1: First you extract all the 'Prime' factors of each number.

The ladders on the image show that you are dividing each number with the smallest prime number. You keep doing it till you reach 1 .

Step 2: Then you write the factors of each.

Step 3: You choose the common factors.

Step 4: Multiply the common factors (if any) and then you have your answer.

Answer:

HCF: 2

LCM: 2576

Step-by-step explanation:

Prime factorizations:

112 = 2×2×2×2×7

46 = 2×23

HCF: 2 (only common factor)

LCM: 2×2×2×2×7×23 = 2576

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)

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:

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

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:

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

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
