Answer:

Yes, they are similar as the difference between the smaller rectangle and the larger one is a scale factor of 2.

answer:

yes

explanation:

you can tell if figures are similar (proportional side lengths with points of the same orientation), if you can divide the respective side lengths of the image and preimage together.

Significant digits are all non-zero numbers. The numbers are none of the zeros significant is 3100.

Significant figures in positional notation are the digits in a number that may be trusted to accurately represent how much of something there is.

Only the digits allowed by the measurement resolution are reliable, and only these can be significant figures if a measurement result is reported as a number with more digits than those allowed by the measurement resolution.

The correct option is (C) 18.84 in. The circumference of the circle with a diameter 6 in is 18.84 in.

A circle's perimeter is known as its circumference. It is the circumference of the circle as a whole. A circle's circumference is calculated by multiplying its diameter by the constant. This measurement of a circle's diameter is necessary for someone crossing a circular park or for enclosing a circle. The units for the circumference, which is a linear variable, are the same as those for length.

Given, the diameter of the circle = 6 in.

The radius of a circle is calculated as

r = d / 2

r = 6 / 2

r = 3 in

The circumference of a circle is calculated as

C = 2πr

Substitute r = 3 in the circumference formula

=2 × 3.14 × 3

= 6 × 3.14

= 18.84 in

In the given sequence, the next term is obtained by multiplying the next term by (-1), hence it is a geometric sequence with r = 1. The next two terms are 3, -3.

Arithmetic sequence.

In a arithmetic sequence, the next term = the previous term + common difference. Or mathematically:

a(n) = a(n-1) + d

or d = a(n) - a(n-1) for all n

Where d = common difference.

Geometric sequence.

In a geometric sequence,  the next term = the previous term x common ratio. Or mathematically:

Using translation concepts, it is found that the transformation is a reflection over the y-axis.

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

For this problem, we have that A is mapped to C and vice-versa. Since they are equidistant to the y-axis, we have that the rule is given by:

(x,y) -> (-x,y).

Meaning that the transformation is a reflection over the y-axis.

When someone cries guiltily, but the person is angry and sad with him/herself is reflex crying.

Verb, adjective, another adverb, determiner, clause, preposition, or sentence is typically modified by an adverb. Adverbs often answer questions like "how," "in what way," "when," "where," and "to what extent" by expressing things like method, place, time, frequency, degree, level of certainty, etc.

Many adverbs have -ly endings, and they frequently follow the word they modify. Adverbs typically give information about an action's when, where, how, and how much it happened.

It should be noted that in literature, an adverb simply means the part of speech that can be used to qualify a verb.

3b ≤ 6

3b/3 ≤ 6/3

b ≤ 2

Explanation: In the 2nd step, I subtracted 2 from both sides. In step 4, I divided both sides by 3. The inequality sign stays the same. It would flip if we multiplied or divided both sides by a negative number.

If you want to graph this on a number line, then plot a closed filled in circle at 2. Then shade to the left. This visually represents numbers that are 2 or smaller.

According to the given statement the slop of the given points are: -(1/2).

The slope of the line is the mathematical ratio of overall rise to the run, or rise divided by the run. It expresses the slope of a line in the coordinate plane. Calculating the slope of a line is comparable to finding the slope between two separate places.

The procedure for calculating the slope from such an equation will vary based on the form of the equation presented to you. If the equation is written as y=mx+c, the slope (or gradient) is simply m. If the formula does not exist in this form, try rearrangement.

The slope of a line is easily calculated by hand using small, whole number coordinates.

so,

X1 = 7

X2 = 3

Y1 = 2

Y2 = 4

Applying the formula for slope:

slope = (y₂ - y₁) / (x₂ - x₁)

         = (4 - 2) / (3 - 7)

         = 2/(-4)

         = - (1/2)

Answer:

Step-by-step explanation:

Step-by-step explanation:

let's just write it down in mathematical notation :

length = 2×width - 1

the perimeter is the way all around an object.

so, for a rectangle that is

2×length + 2×width

for our rectangle here

2×length + 2×width = 70

now we use the original identity of length via width and get

2×(2×width - 1) + 2×width = 70

4×width - 2 + 2×width = 70

6×width - 2 = 70

6×width = 72

width = 12

FYI

length = 2×width - 1 = 2×12 - 1 = 24 - 1 = 23

Step-by-step explanation:

The simplification by combining like terms  of 3a + b + a is 4a + b.

According to the given question.

We have an expression 3a + b + a.

As we know that, like terms are terms whose variables (and their exponents such as the 2 in x2) are the same.  when we combine like terms, such as 2x and 3x, we add or subtract their coefficients.

Since, we have to combine the like terms of the given expression  3a + b + a.

Here 3a and a both are the like terms.

So, we add coeffcients of a to simplify the given expression.

Therefore, the simplification of 3a + b + a is given by

3a + b + a

= 3a + a + b

= 4a + b

Hence, the simplification by combining like terms  of 3a + b + a is 4a + b.

A linear equation is an algebraic equation of degree one. In general, the variable or the variables(in the case of a linear equation in two variables) the variables are x and y.

Let the cost of 1 phone is x dollars and cost of 1 computer is y dollars.

Cameron earns a 4% commission on the total dollar amount of all phone sales he makes and earns a 6% commission on all computer sales.

∴ (4/100)x + (6/100)y = 178
