Answer:

Should have taken the absolute value

Actual length = 3.5 centimeters

Step-by-step explanation:

Length is always a positive value or zero

So one should take the absolute value which is always positive

|-3.5| = 3.5 where the | | denotes absolute value of what is enclosed

Answer:

9/7

Step-by-step explanation:

-24/35 ÷ -8/15

=-24/35 × -15/8

=9/7

Answer:

9/7

Step-by-step explanation:

when dividing with a fraction, the -8/15 reciprocates to 15/-8. Then, -8 cancels out -24 remaining with 3 since they are both negative while 15 and 35 have a common of 5 giving them a remainder of 3 and 7 respectively. you then multiply what you have which is 3/7 * 3/1 giving you 9/7.

Answer:

The correct answer is City D.

Step-by-step explanation:

When you say the phrase, "closer to sea level" you mean the closest to the very top of the sea, like "0" on a number line.

This means, that whether it is to the left of the right of the number line (or above or below the sea) whichever one has the lowest absolute value is the closest.

Therefore, the correct answer is City D.

Hope this helps! :D

Answer:

-1 + 6i

Step-by-step explanation:

Subtract/add the imaginary parts and then add real parts.

Open the parenthesis by multiplying the each term of 4 - 2i by (-1)

3 + 4i - (4 - 2i) = 3 + 4i - 4 + 2i

                       = 3 - 4 + 4i + 2i

                       = -1 + 6i

Answer:

C (x = 2)

Step-by-step explanation:

Since x is a non-negative number, A and B are eliminated.

This leaves C and D.

C: x = 2,

2 + 3 < 2^2

5 < 4 is false.

So C would be a counterexample.

Hope this helps!

The value of x is a counterexample to the student's conjecture (x = 2). The correct option is C.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that x is a non-negative number, a student conjectured that x + 3 < x².

Since x is a non-negative number, A and B are eliminated.

This leaves C and D at the value of x = 2,

2 + 3 < 2²

5 < 4 is false.

Therefore, the value of x is a counterexample to the student's conjecture (x = 2). The correct option is C.

Answer:

[tex]\frac{7}{16}[/tex] in., [tex]\frac{5}{8}[/tex] in., [tex]\frac{3}{4}[/tex] in., 1[tex]\frac{5}{16}[/tex] in., 1[tex]\frac{3}{2}[/tex] in.

Step-by-step explanation:

Diameters of the belt produced are given in fractions which can be converted to decimals to know their values.

Thus,

1 3/2 in. = [tex]\frac{5}{2}[/tex] in. = 2.5 in.

7/16 in. = 0.4375 in.

3/4 in. = 0.75 in.

5/8 in. = 0.625 in.

1 5/16 in. = [tex]\frac{21}{16}[/tex] in. = 1.3125 in.

Arranging the vales from least to greatest, we have;

0.4375 in., 0.625 in.,0.75 in., 1.3125 in., 2.5 in.  = [tex]\frac{7}{16}[/tex] in., [tex]\frac{5}{8}[/tex] in., [tex]\frac{3}{4}[/tex] in., 1[tex]\frac{5}{16}[/tex] in., 1[tex]\frac{3}{2}[/tex] in.

Answer:

The image of P(11,-4) will be: P'(-6, -2)

Step-by-step explanation:

Given the point

The rule:

(x, y) = (x– 17, y+2)

Meaning the image of P(11,-4) can be determined by subtracting 17 units (moving left) from the x-values and adding 2 units (moving up) to the y-values.

Therefore,

P(11, -4) → P'(11-17, -4+2) = P'(-6, -2)

Thus, the image of P(11,-4) will be: P'(-6, -2)

Let's list what we know.

We know 6 + d is the same as 21

We can use this.

6+d=21

Subtract 6 from both sides

d=15

So d=15

21-6=15

[tex]H = \frac{SA}{2(L+W)} - \frac{LW}{L+W}\\\\[/tex]

=================================================

Work Shown:

[tex]SA = 2(LW + LH + HW)\\\\2(LW + LH + HW) = SA\\\\LW + LH + HW = \frac{SA}{2}\\\\LH + HW = \frac{SA}{2} - LW\\\\H(L + W) = \frac{SA}{2} - LW\\\\H = \frac{\frac{SA}{2} - LW}{(L + W)}\\\\H = \frac{SA}{2(L+W)} - \frac{LW}{L+W}\\\\[/tex]

This is not the only way to solve for H.

Answer:

confused on what you are asking

Step-by-step explanation:

Answer:

slope is m= 5/7

Step-by-step explanation:

m= y2-y1/x2-x1

m= 3-(-2)/ 9-2

m= 5/7

Slope = change in Y over change in X

Slope = (3- -2) / (9 - 2)

Slope = 5/7

The option b and c is correct.

To solve this problem we must be aware of the concepts of line segment. And also what is a mid point.

When we connect two dots or two points it forms a line segment or we can say that line segment is part of line which is bounded by two points.

Mid-point of any line or line segment is that point which divides the line segment into two equal parts and also a point which is equidistant from the two endpoints.

So, a midpoint of a line segment divides the line segment in two equal parts and is also equidistant from the two endpoints.

Here, the appropriate option is b and c.
