Answer:

x = 48

Step-by-step explanation:

To solve this problem, one must assume that the segment with a length of (7) bisects the segment with a length of (x).

It is given that the segment with a length of (7) is perpendicular (forms a right angle with) the segment that has a length of (x). This is indicated by the box around one of the angles, signifiying that it is a right angle, or (90) degree angle. Therefore, the triangle with sides measuring (25) and (7) is a right triangle. Thus, one can use the Pythagorean theorem to solve for the base length. Then multiply it by (2) to find the total length of (x).

The Pythagorean theorem states the following:

[tex]a^2+b^2=c^2[/tex]

Where (a) and (b) are the legs, or sides adjacent to the right angle, and (c) is the hypotenuse or side opposite the right angle.

[tex]a^2+(7)^2=(25)^2[/tex]

Simplify,

[tex]a^2+49=625[/tex]

Inverse operations,

[tex]a^2=576\\\\a=24[/tex]

Multiply this value by (2) to find the total side length of the segment (x),

2(a)

Substitute,

2(24)

Simplify,

48

Answer:

3 or -3

Step-by-step explanation:

What number multiplied by itself will give you 9

1*1 =1

2*2 =4

3*3 =9

Also note that negative times negative will be positive so

-1*-1=1

That means -3*-3 = 9

Answer:

3^2 0r (-3)^2

Step-by-step explanation:

let the number be x

x^2=9

x=[tex]\sqrt{9[/tex]

x=[tex]\sqrt{3*3[/tex]

x=3

there fore x=plus or minus 3.since it is a sqauring a number if u square (-3)^2 along will the number sign also gets multiplied and (-*-)=+ so u we get positive number.

therefore if u square 3 then u will get 9

Answer:

A= $40584.28      

Step-by-step explanation:

P = 36000

r = 12% = 0.12

n = 52 weeks

t = 1

[tex]A = P(1 + \frac{r}{n})^{nt}\\[/tex]

   [tex]=36000(1 + \frac{0.12}{52})^{52 \times 1}\\\\=36000 (1.002307)^{52}\\\\=36000 \times 1.12734\\\\=40584.28[/tex]

Answer:

9x² - 7x - 9

Step-by-step explanation:

Two sides

Answer:

week: 223

Year: 11596

Step-by-step explanation:

Answer: a) $223; b) $11,596

Step-by-step explanation:

1 week: 11.15/hr * 20hrs/week = 223

Year = 52 weeks; 52 * 223 = 11,596

Answer:

That's a Trapezium

Area =½( A + B)x H

A and B are the top and bottom of the shape.

H is the height.

Substituting...

Area = ½(13+17)8

=120 Square Inches

Answer:

B. 120 in.²

Step-by-step explanation:

13 × 8 = 104 in.²

17 - 13 = 4

4 × 8 = 32

32 ÷ 2 = 16

16 in.² + 104 in.²

120 in.²

Answer:

35 because i had this problem before and the answer was 35 cuz yeah

Answer: (2,0), (2,1), and (6,1)

Step-by-step explanation: I just used the desmos graphing calculator to find the answer to your problem. I don't know any formulas to solve it so I just rotated the points by hand. I also made sure they were still equidistant from the point (2,-1) because if their distances from other points changed during the rotation, then the triangle would not be equal to the first triangle and the image would've been distorted.

I hope this helps! Have a nice day.

Answer:

(1, -1.5)

Step-by-step explanation:

To find the x coordinate of the midpoint, add the x values and divide by 2

(-4+6)/2 = 2/2 = 1

To find the y coordinate of the midpoint, add the y values and divide by 2

(-5+2)/2 = -3/2 = -1.5

Answer:

360

Step-by-step explanation:

All circles can be divided into 360 units called degrees. Since there is 270 already we subtract 270 from 360.

360 - 270 = 90

90 + 150 + 120 = 360

Step-by-step explanation:

Step 1: Define

Identify

[tex]\displaystyle\displaystyle g(x) = \lim_{h \to 0} \frac{f(x + h) - f(x)}{h}[/tex]

[tex]\displaystyle f(x) = \frac{3}{5x^4 + 3}[/tex]

[tex]\displaystyle g(0)[/tex]

Step 2: Differentiate

Since the bottom polynomial has a higher degree than the top polynomial, the bottom polynomial will increase faster.

∴ If the bottom is approaching a bigger value, the fraction gets smaller and smaller, approaching 0.

Hi there!

[tex]\large\boxed{3\text{ } \frac{3}{4} cm^3}[/tex]

Knowing that one cube has side-lengths of 1/2, we can calculate the dimensions for the prism:

Length: 1/2 × 5 = 2.5 cm

Height: 1/2 × 3 = 1.5 cm

Width: 1/2 × 2 = 1 cm

Use this formula to solve for the volume:

V = l × w × h

Thus:

V = 2.5 × 1.5 × 1 = 3.75 cm³

Convert to fraction:

75/100 = 3/4

Thus, the volume in mixed-numbers is 3 3/4 cm³.

Answer:

A [and B]

Step-by-step explanation:

If x < 5.3 then anything higher than 5.3 makes the statement false.

16 is too high and therefore is the most obvious fallacy.

5.3 would actually make x=5.3 and therefore x wouldn't be less than 5.3 making it also false but this really depends on what your teacher is looking for.

0 is true.

-8.95 is true.

If there is any clarification in the problem you can provide I can give a more definite answer but now it is really a coinflip!

Answer:

-0.0390625

Step-by-step explanation:

each is cut in half

so we do this

20, 10, 5, 2.5, 1.25, .625, .3125, .15625, 0.078125, 0.0390625

Answer:

x =145/129

Step-by-step explanation:

129x-33=112

Add 33 to each side

129x-33+33=112+33

129x = 145

Divide each side by 129

129x/129 = 145/129

x =145/129

Answer:

It is supplementary.

Step-by-step explanation:

Supplementary angles are angles that have two angles adding up to 180°. You can tell by just finding the straight line that equals 180° then seeing a line that separates the whole measurement into two angles, but together making a 180° angle still. Hope this helps! :D

Meanings of the other Options:

Alternate Interior Angles - Angles formed when two parallel or non-parallel lines are intersected by a transversal. The angles are positioned at the inner corners of the intersections and lie on opposite sides of the transversal.

Corresponding Angles - Angles that are in the same relative position at an intersection of a transversal and at least two lines. If the two lines are parallel, then the corresponding angles are congruent.

Alternate Exterior Angles - Angles are the pair of angles that lie on the outer side of the two parallel lines but on either side of the transversal line. Exterior angles lie on opposite sides of the transversal but outside the two parallel lines.

Parallel Lines - Two lines that never intersect. Like an equal sign for example (=).

Transversal - A line the cuts through a parallel line. Like a non-equal sign for example (≠).

Answer:
