Answer:

try drawing a circle or an oval

Step-by-step explanation:

There are no edges or corners to a circle, ovals, or semicircles, making it a spherical form. Shapes may be categorized and sorted using these qualities as well as size.

A group of points that are all at the same distance from a fixed point is how it is characterized (called the center of a circle).

Ovals, semicircles, circles, and other closed forms all lack straight lines. Having one curved edge and one straight edge, a semicircle is a closed form.

An oval is a circle that has been flattened such that it resembles an egg or an ellipse: a mirror with an oval shape; a face with an oval shape. Ellipsoidal comparison.

By dividing a circle into two equal halves along the diameter line, a semicircle is created. There is just one line of symmetry in the semicircle, and that is the reflection symmetry. A half-disk is another name for the semicircle.

Thus, the flat shape that has no straight will be ovals, semicircles, and circles.

Answer:

4/3=x+10/15

x=4/3 - 10/15

x=4/3 - 2/3

x=4-2/3

x=2/3

Answer:

x = 16.957

Step-by-step explanation:

(3/5)x - 6 = (-1/6)x + 7

Add (1/6)x to both sides. Add 6 to both sides.

(3/5)x + (1/6)x = 7 + 6

(18/30)x + (5/30)x = 13

(23/30)x = 13

Multiply both sides by 30/23.

x = 13/1 * 30/23

x = 390/13

x = 16.957

There will be twelve and a half city blocks of the street sweepers clean on Tuesday.

The numerator, which is found at the top of the fraction number, and the denominator, which is located at the bottom, are its two component components.

It is given that, four city blocks were cleaned by a crew of street sweepers on Monday. The crew cleaned 2 1/6 as many blocks on Tuesday as they did on Monday.

Suppose the number of city blocks the street sweepers cleaned on Tuesday will be x,

x = 4 +  2 1/6 × 4

x=4+13/6×4

x=12.6≈ 12 1/2

Thus, the street sweepers will clean twelve and a half city blocks on Tuesday.

Answer:

first term (a) = 54

Second term (b) = 18

common ratio = b/a = 18/54 = 1/3

Answer:

6 - 4a

Step-by-step explanation:

From the question given,

f(x) = 2 - x

2f(a) + f(2a) =.?

First, we shall obtain f(a). This can be obtained as follow:

f(x) = 2 - x

x = a

f(a) = 2 - a

Next, we shall obtain 2f(a). This is can be obtained as follow:

f(a) = 2 - a

2f(a) = 2(2 - a)

2f(a) = 4 - 2a

Next, we shall obtain f(2a). This can be obtained as follow:

f(x) = 2 - x

x = 2a

f(2a) = 2 - 2a

Finally, we shall determine 2f(a) + f(2a) as follow:

2f(a) = 4 - 2a

f(2a) = 2 - 2a

2f(a) + f(2a) =?

2f(a) + f(2a) = (4 - 2a) + (2 - 2a)

2f(a) + f(2a) = 4 - 2a + 2 - 2a

2f(a) + f(2a) = 4 + 2 - 2a - 2a

2f(a) + f(2a) = 6 - 4a

Therefore, 2f(a) + f(2a) is equivalent to 6 - 4a

Answer:

  Nora is correct

Step-by-step explanation:

Sophia used an appropriate method for computing the value of the repeating decimal fraction ...

  0.1212_12

Close examination of the given decimal fraction shows that it is non-repeating, so is an irrational number. It cannot be represented by the ratio of integers.

Nora is correct in saying Sophia made a mistake.

___

Sophia depended on 100x -x cancelling some part of the fraction, so the result was a finite decimal. For repeating 2-digit fractions, this works well:

  [tex]x=0.12\overline{12}\\100x=12.12\overline{12}\\100x-x=12.12\overline{12}-0.12\overline{12}=12\\x=12/99[/tex]

However, the decimal does not repeat, so this does not work:

  100x = 12.1121112

  100x -x = 12.1121112 -0.121121112 = 11.99099009900099... non-repeating

That is, the decimal part is not cancelled by Sophia's work, as we said above.

C²= A²+B²

Step-by-step explanation:

A) 10²=( Base)² + 6²

(Base )²= 10² - 6²:

Base = √ 64

8

B) 17² = 8² + (Height)²

(Height) ² = 17²- 8²

= 289-64

= 225

Height = √225

= 15

C) 2.5² = Base ² + 1.5 ²

Base² = 2.5 ²- 1.5²

6.25- 2.25

= 4

Base = √4

= 2

D) 41² = Base²+ 40²

Base²= 41²- 40²

1681-1600

= 81

Base = √81

=9

E)26²=Base² +10²

Base² = 26²- 10²

676-100

Base= √576

F)25²= Base²+ 7²

Base² = 25²- 7²

Volume of wheelbarrow , V = 2 1/2 ft³ = 5/2 ft³.

Volume of soil in wheelbarrow , [tex]v = \dfrac{5}{3}\ ft^3[/tex] .

Mass of soil in wheelbarrow , m = 75.25 pounds.

Now, volume left , [tex]v'=\dfrac{5}{6}\ ft^3[/tex] .

Let, mass of  soil un wheelbarrow is x.

[tex]x=\dfrac{\dfrac{5}{6}\times 75.25}{\dfrac{5}{3}}\\\\x=37.625\ pounds[/tex]

Hence, this is the required solution.

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

Explanation:

The given ordered pair is (4, ___) so we have x = 4 here.

We will plug this into f(x) and g(x) to get

f(4) = 6

g(4) = 7

So we have [tex]\frac{f(4)}{g(4)} = \frac{6}{7}[/tex]

-----------

If you're curious where f(4) = 6 came from, all we're doing is looking through the set of points

f = {(0, 1), (2, 4), (4, 6), (6, 8)}

to see which has 4 listed first as the x coordinate. That point is (4,6) so x = 4 leads to y = 6, ie, f(x) = 6 when x = 4. A similar situation happens with g(x) as well.

The solution to the equation 3x + 7 = 16 - 2x is x = 9/5.

Option A is the correct answer.

We have,

To solve the equation 3x + 7 = 16 - 2x for x, we need to isolate the variable x on one side of the equation.

Let's solve it step by step:

Start with the original equation:

3x + 7 = 16 - 2x

- Add 2x to both sides of the equation to get rid of the -2x on the right side: 3x + 2x + 7 = 16 - 2x + 2x

- Simplifying, we have: 5x + 7 = 16

- Next, subtract 7 from both sides of the equation to isolate the term with x: 5x + 7 - 7 = 16 - 7

- Simplifying, we have: 5x = 9

- Finally, divide both sides of the equation by 5 to solve for x: (5x)/5 = 9/5

- Simplifying, we have: x = 9/5

Therefore,

The solution to the equation 3x + 7 = 16 - 2x is x = 9/5.

Step-by-step explanation:

Let the distance points E(3,7) and F(6,5)

Distance between EF = √[(x2-x1)²+(y2-y1)²]→Formula

Here, x1 = 3, y1 = 7

x2 = 6 , y2 = 5

Now,

Put all the values in distance formulae:

AB = √[(6-3)²+(5-7)²]

= √[(4)²+(2)²]

= √[(4*4)+(2*2)]

= √[16+4]

= √[20] = 2√5 Units.

Answer:- Hence, the distance between two points E(3,7) and F(6,5) is 2√5 Units.

1 / 4c+5

Step-by-step explanation:

Given :

4c + 5 ≠ 0

c is a real number.

Find the multiplicative inverse of equation ?

The multiplicative inverse of a number is reciprocal of number

Let

x = a number

The multiplicative inverse = 1/x

Let 4c + 5 ≠ 0 be a number x

Then, the multiplicative inverse of x = 1/x

x = 4c + 5

1/x = 1 / 4c+5

Therefore, the multiplicative inverse of 4c + 5 = 1 / 4c+5
