Answer:

1.48502 × 10²

Step-by-step explanation:

A number expressed in standard form is

a × [tex]10^{n}[/tex] ( 1 ≤ a < 10 and n is an integer )

Given

148.502 ← express as a number between 1 and 10

1.48502

To obtain the original number we require to multiply by 100 , that is 10²

Thus

148.502 = 1.48502 × 10²

Answer:

[tex]1.48502 \times {10}^{2} [/tex]

Step-by-step explanation:

To convert to standard form, move the decimal point until there is one digit to the left of the decimal point.

Since the decimal point moves to the left, the exponent value goes up. If the decimal point moves to the right, the exponent value gpes down.

In this case, since the decimal point moves to the left twice, then the exponent goes up by 2.

Hope this helps!

Answer:

x = 3.5

Step-by-step explanation:

Given

[tex]3^{2x-5}[/tex] = 9 , that is

[tex]3^{2x-5}[/tex] = 3²

Since the bases on both sides are equal, both 3 , then equate the exponents

2x - 5 = 2 ( add 5 to both sides )

2x = 7 ( divide both sides by 2 )

x = 3.5

Step-by-step explanation:

Answer:

The answer is 15.

Step-by-step explanation:

Plug in the numbers for the a and b values individually.  For the numerator, 5(6) is the same thing as 5 * 6 = 30.  For the denominator, 1/4^2 would equal to 1/16 and when you multiply it by 32, you will get 2.

To clear things up, the fraction should be 30/2 and your answer should be 15 as a result.

Step-by-step explanation:

so...the answer is 15

Step-by-step explanation:

because

12xy³z⁶/4x⁵yz¹²=3y²/x⁴z⁶

The division of (12xy³[tex]z^6[/tex])/ (4[tex]x^5[/tex]y[tex]z^{12[/tex]) is 3y²/ [tex]x^4[/tex][tex]z^6[/tex].

A polynomial is a mathematical equation that solely uses the operations addition, subtraction, multiplication, and non-negative integer exponentiation of variables. Variables are sometimes known as indeterminates in mathematics.

Given:

(12xy³[tex]z^6[/tex])/ (4[tex]x^5[/tex]y[tex]z^{12[/tex])

Now, expand for the division

12/4= 3

x / [tex]x^5[/tex] = 1/ [tex]x^4[/tex]

y³ /y = y²

[tex]z^6[/tex] / [tex]z^{12[/tex]= 1/[tex]z^6[/tex]

So, the division is

(12xy³[tex]z^6[/tex])/ (4[tex]x^5[/tex]y[tex]z^{12[/tex])

= 3y²/ [tex]x^4[/tex][tex]z^6[/tex]

Answer:

D. 1/2m + 25

Step-by-step explanation:

Sophie pays m dollars to rent a car for the weekend.

On the drive home, she buys $25 worth of gasoline.

From the above question, we are told that:

Her friend Melody pays for one-half the cost of the car rental only.

= m - 1/2m

= 1/2m

Hence, the cost of the rental that sophie is paying for is 1/2m dollars

She buys $25 of gasoline

Let the amount sophie spent be represented by A

The expression you could use to determine how much Sophie spent is given as:

A = 1/2m + 25

Answer:

1/2 + 25

Step-by-step explanation:

Don't feel like explaining. :)

Step-by-step explanation:

We know that perimeter is the sum of all sides

= 2x³ + 6x + 4x³ - 5x + 6x³ + x

Find the explanation below.

Step-by-step explanation:

Statements simply state the theorem that is to be proofed. Formal proof in logical sequence connects the hypotheses to the conclusion reached.

Statements and reasons are important because they help to breakdown a theorem, showing in steps and stages how a conclusion was reached. They provide facts that convince the observer that the theorem is indeed true.

Answer:

The reason is likely because of an unit error of centimetres square (cm²) which is to be in metres square (m²)

Step-by-step explanation:

The units of the length is in meters, and the side length, S, of the cube is S = 0.7 m, therefore, the answer is to be given as follows;

The surface area of one face of the cube = S² = (0.7 m)² = 0.49 m²

The number of faces in a cube = 6, therefore, we have;

The surface area of the cube = 6 × The surface area of one face of the cube

The surface area of the cube = 6 × 0.49 m² = 2.94 m²

Therefore, the surface area of the cube is 2.94 m² (m² not cm²)

Answer: No -1 is not an irrational number.

Step-by-step explanation: The number 1 can be classified as a natural number, a whole number, a perfect square, a perfect cube, an integer. This is only possible because it is a rational number, not irrational.

Answer:

113.097

Step-by-step explanation:

so Basically to find the area of this cylinder have to set up to equation ((2)6pi)3

first you multiply 2 x 6 getting you 12 then multiply it by pi which in mathematical terms is 37.7 multiplied by 3, getting you 113.097

which can be simplified to 113

The surface area of the cylinder with height 3 cm and radius 6 cm is 340 cm².

The surface area of a figure is the number of unit squares it takes to cover the entire surface without gaps or overlaps. If a three-dimensional figure has flat sides, the sides are called faces.

Given that, the cylinder with height 3 cm and radius 6 cm, we need to find its surface area,

SA of a cylinder = 2 π × radius × (height + radius)

= 2 × 3.14 × 6 × (3+6)

= 2 × 3.14 × 6 × 9

= 339.12

≈ 340

Hence, the surface area of the cylinder with height 3 cm and radius 6 cm is 340 cm².

Answer:

t

Step-by-step explanation:

This one is very simple.

The triangle on the left has two equal sides, so the angle on the opposite side of that same triangle is also 52º. That angle is on a 180º line, so the angle right next to it has to be 180º - 52º, so 128º. The other two angles of that triangle are unknown, but still equal because of the sides being the same. So, subtract 128º from 180º to get 52º again, but divide it by two. The angle measurement of x = 26º

The degree of the polynomial

In order to determine the degree of the polynomial, we need to check the term with the highest of the degree with non-zero coefficients. The degree of an individual term is basically the exponent of the term.

In our case,

The exponents of the terms of this polynomial are, in order, 6, and 3.

Thus, the highest degree (larger exponent) of the term is 6.

Answer:

  (-2, 2)

Step-by-step explanation:

The orthocenter is the intersection of the altitudes. The altitude lines are not difficult to find here. Each is a line through the vertex that is perpendicular to the opposite side.

Side XZ is horizontal, so the altitude to that side is the vertical line through Y. The x-coordinate of Y is -2, so that altitude has equation ...

  x = -2

__

Side YZ has a rise/run of -1/1 = -1, so the altitude to that side will be the line through X with a slope of -1/(-1) = 1. In point-slope form, the equation is ...

  y -(-1) +(1)(x -(-5))

  y = x +4 . . . . . . . . subtract 1 and simplify

The orthocenter is the point that satisfies both these equations. Using the first equation to substitute for x in the second, we have ...

  y = (-2) +4 = 2

The orthocenter is (x, y) = (-2, 2).
