Answer:

Pio is paid with $ 401.25 for 51 hours in a week.

Step-by-step explanation:

Based on the information of the statement we can calculate his payment for 51 hours in a week but using this arithmetical formula:

[tex]c = 7.50\,\frac{\$}{h}\times 46\,h + 1.5\times 7.50\,\frac{\$}{h}\times (51\,h-46\,h)[/tex]

[tex]c = \$\,401.25[/tex]

Please notice that first component of the sum represent the ordinary time in a week (46 hours) and the second one, extra work time.

Answer:

994.88 in2

Step-by-step explanation:

Use the surface area formula SA = 4(pi)(r2) which results in SA = 4(3.14)((8.9)2) = 994.88 square inches. Because the bowl represents half a sphere, it is necessary to divide that answer by 2 to get the surface of the bowl.

If radius of a salad bowl is 8.9 inches then the surface area of the bowl is 497.44 square inches, option c is correct.

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

Given that  radius of a salad bowl is 8.9 inches.

We have to find the  surface area of the bowl

The surface area of a half-sphere is given by the formula:

SA = 2πr²

where r is the radius of the sphere.

In this case, the radius of the salad bowl is 8.9 inches.

Substituting this value into the formula, we get:

SA = 2 x 3.14 x (8.9)²

SA = 497.44 square inches

Surface area =497.44 square inches

Hence, if radius of a salad bowl is 8.9 inches then the surface area of the bowl is 497.44 square inches, option c is correct.

Answer:

5000 cm3

ps:im not that sure but try it

Step-by-step explanation:

1 litre = 1000 cm3

5 litre=5000

The volume of the 5 litre tin is 5000 cm³.

A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity.

We have to convert the capacity of a 5 litre tin to its volume in cm

Given that 1 litre is equal to 1000 cm³.

Therefore, 5 litres is equal to 5 times of thousand

5 litres × 1000 cm³/litre

= 5000 cm³

Therefore, the volume of the 5 litre tin is 5000 cm³.

Number of white marble added for same probability is 2

Given:

Number of red marble in box = 7

Number of white marble in box = 4

Number of blue marble in box = 5

Probability of drawing a white marble = 1/3

Find:

Number of white marble added for same probability

Computation:

Assume;

Number of white marble added = a

[tex]Probability = \frac{Number\ of\ favorable\ outcomes}{total\ outcomes}[/tex]

So,

[tex]\frac{1}{3} = \frac{(a + 4)}{(7 + 4 + 5 + a)} \\\\\frac{1}{3} = \frac{(a + 4)}{(16 + a)} \\\\16 + a = 3a + 12 \\\\ 2a = 4\\\\a = 2[/tex]

The triangles are similar. We are told they are similar with the angles in this order:

LMN

ZXY

That means L is similar to Z, M is similar to X, and N is similar to Y.

That also means that side LM is similar to side ZX, side MN is similar to side XY, and side LN is similar to side ZY.

isn't it that a parallelogram has 6 sides and these are 4?????????............

Answer:

x = 11

Step-by-step explanation:

The angles in a square are right , that is 90°

The diagonals bisect the angles , then

6x - 21 = 45 ( add 21 to both sides )

6x = 66 ( divide both sides by 6 )

x = 11

Answer:

15/9= 1 6/9

Step-by-step explanation:

8/9+ 7/9 is basically doing 8+9. But remember you need a common denominator to add fractions.

Answer:

The sides of an angle are the rays of the angle. So,

1)The sides of ∠YVW are the 2 rays of the angle VY and VW

2)The sides of ∠XVY are the 2 rays of the angle VX and VY

Angles adjacent to an angle are the angles next to the main angle

3)The angle adjacent to ∠ZVW is ∠YVZ and ∠WVX

4)The angle adjacent to ∠XVZ is ∠ZVW and ∠XYW

5)The angle adjacent to ∠YVZ is ∠ZVW and ∠YVX

The side common to the angles is the common ray of both angles

6)The side common to ∠XVY and ∠YVZ is ray VY

7)The side common to ∠XVZ and ∠ZVW is ray VZ

8)The side common to ∠XVZ and ∠ZVY is ray VZ

9)The side common to ∠XVY and ∠YVW is ray VY

The common vertex is the point where all rays converg,

10)The common vertex is V

Answer:

Exercise 1: The length of the unknown leg is 4 inches.

Exercise 3: The following straws can be used to construct the triangle: b) [tex]3\,in[/tex], c) [tex]4.5\,in[/tex], d) [tex]6.5\,in[/tex], e) [tex]10\,in[/tex], f) [tex]13.5\,in[/tex]

Exercise 4: Possible options of this exercise: 1) (2, 4, 5), 2) (4, 5, 6), 3) (5, 6, 10), 4) (1, 2, 11), 5) (1, 4, 11), 6) (1, 10, 11)

Step-by-step explanation:

Exercise 1:

Let suppose that triangle represented in the figure is a right triangle, the length of the missing leg is determined by Pythagorean Theorem:

[tex]y = \sqrt{l^{2}-x^{2}}[/tex] (1)

Where:

[tex]l[/tex] - Hypotenuse, in inches.

[tex]x[/tex] - Known leg, in inches.

[tex]y[/tex] - Unknown leg, in inches.

If we know that [tex]l = 11\,in[/tex] and [tex]x = 10\,in[/tex], then the length of the unknown leg is:

[tex]y = \sqrt{21}[/tex]

Since 4 is the least whole number closest to [tex]\sqrt{21}[/tex], then we conclude that the length of the unknown leg is 4 inches.

Exercise 3:

The range of possible lengths for the missing side of the triangle is represented by the following simultaneous inequality:

[tex]x + y > l > x-y[/tex] (2)

Where:

[tex]x[/tex] - Greater side, in inches.

[tex]y[/tex] - Lesser side, in inches.

[tex]l[/tex] - Missing side, in inches.

If we know that [tex]x = 8\,in[/tex] and [tex]y = 6\,in[/tex], then we have the following range of missing sides:

[tex]14\,in > l > 2\,in[/tex]

The following straws can be used to construct the triangle: b) [tex]3\,in[/tex], c) [tex]4.5\,in[/tex], d) [tex]6.5\,in[/tex], e) [tex]10\,in[/tex], f) [tex]13.5\,in[/tex]

Exercise 4:

Let check each pair to determine possible constructions by means of the inequality used in Exercise 3:

(i) [tex]x = 4\,in, y = 2\,in[/tex]

[tex]6\,in>l>2\,in[/tex]

Possible choices: 5 inches.

(ii) [tex]x = 5\,in, y = 2\,in[/tex]

[tex]7\,in > l > 3\,in[/tex]

Possible choices: 4 inches, 6 inches.

(iii) [tex]x = 6\,in, y = 2\,in[/tex]

[tex]8\,in > l > 4\,in[/tex]

Possible choices: 5 inches, 6 inches.

(iv) [tex]x = 10\,in, y = 2\,in[/tex]

[tex]12\,in > l > 8\,in[/tex]

Possible choices: None.

(v) [tex]x = 5\,in, y = 4\,in[/tex]

[tex]9\,in > l > 1\,in[/tex]

Possible choices: 2 inches, 6 inches.

(vi) [tex]x = 6\,in, y = 4\,in[/tex]

[tex]10\,in > l > 2\,in[/tex]

Possible choices: 5 inches.

(vii) [tex]x = 10\,in, y = 4\,in[/tex]

[tex]14\,in > l > 6\,in[/tex]

Possible choices: None.

(viii) [tex]x = 6\,in, y = 5\,in[/tex]

[tex]11\,in > l > 1\,in[/tex]

Possible choices: 2 inches, 4 inches, 10 inches.

(ix) [tex]x = 10\,in, y = 5\,in[/tex]

[tex]15\,in > l > 5\,in[/tex]

Possible choices: 6 inches.

(x) [tex]x = 10\,in, y = 6\,in[/tex]

[tex]16\,in > l > 4\,in[/tex]

Possible choices: 5 inches.

Possible options of this exercise: 1) (2, 4, 5), 2) (4, 5, 6), 3) (5, 6, 10), 4) (1, 2, 11), 5) (1, 4, 11), 6) (1, 10, 11)
