June and Stella can each create six floral arrangements in one hour. If they take in 372 Valentine’s Day orders, how many hours will they need to fulfill them?

Answer:

Option 3: 300 phones

Step-by-step explanation:

Given

Phone produces each day: 1000

Number of phones that were checked = 30

Defective phones = 9

So the probability of defective phones will be calculated by dividing the number of defective phones by total number of phones checked.

So, the probability of defective phones

= 9/30

= 0.3 or 30%

So, from 1000 phones the defective phones will be:

1000*0.3

= 300 Phones ..

Answer:

44, 46

Step-by-step explanation:

The integers are both even, so if the smaller one is x, then the larger one is x+2.

Therefore:

((x) + (x+2))² = 4048 + (x)² + (x+2)²

(2x + 2)² = 4048 + x² + x² + 4x + 4

4x² + 8x + 4 = 2x² + 4x + 4052

2x² + 4x - 4048 = 0

x² + 2x - 2024 = 0

(x + 46) (x - 44) = 0

x = -4+, 44

Since x must be positive, x = 44.  And x+2 = 46.  So the numbers are 44 and 46.

Let's check:

(44 + 46)² = 8100

4048 + 44² + 46² = 8100

To find the measure of ∠ONK in rectangle MPKN with given conditions, it's determined through the congruency of triangles and properties of a rectangle that ∠ONK is 72°.

The question involves finding the measure of ∠ONK in rectangle MPKN, where the diagonals intersect at point O, and a line segment OA is an altitude of triangle MOP with m∠AOP = 18°. Given the properties of a rectangle, we know that its diagonals bisect each other and are equal in length. Therefore, triangles MOP and NOP are congruent.

Because OA is the altitude to hypotenuse MP of triangle MOP, it creates two right triangles, OAM and OAP. The angle ∠AOP is given as 18°, which means ∠MOA = 90° - 18° = 72° since triangle OAM is a right-angled triangle. Because the diagonals of the rectangle bisect each other at O, triangle ONP is congruent to triangle OMP, and hence ∠ONK (which is also ∠ONP) is equal to 72° as angle ∠ONP is supplementary to ∠MOA in rectangle MPKN.

I got this correct on Odyssey:)

Answer:

Option B.

Step-by-step explanation:

∠1 and ∠3 are supplementary and ∠2 and ∠4 are supplementary.

Because they are exterior sides in opposite rays.

In other words ∠1 + ∠3 = 180° and ∠2 + ∠4 = 180°

and it is given that ∠1 ≅ ∠2

So ∠3 ≅ ∠4

Since Two angles supplementary to equal angles are equal will be the reason.

Option B is the correct option.

Answer:

The correct option is C.

Step-by-step explanation:

If a line passing through two point then the equation of line is

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

From the given graph it is clear that the line of best fit passing through the points (0,0) and (14,45). So, the equation of line of best fit is

[tex]y-0=\frac{45-0}{14-0}(x-0)[/tex]

[tex]y=\frac{45}{14}x[/tex]

The equation of line of best fit is [tex]y=\frac{45}{14}x[/tex], therefore the correct option is C.

Answer:

48 cm²

Step-by-step explanation:

Let's call the width and height of the rectangle w and h.

w / h = 3 / 4

2w + 2h = 28

Solve the system of equations with substitution.

w = 3/4 h

2 (3/4 h) + 2h = 28

3/2 h + 2h = 28

7/2 h = 28

h = 8 cm

So the width is:

w = 3/4 (8)

w = 6 cm

So the area is:

A = wh

A = 48 cm²

Answer:

Step-by-step explanation:

step 1

Find the distance from the base of the building to the base of the radio tower

Let

x -----> the distance from the base of the building to the base of the radio

we know that

tan(36°)=254/x

x=254/tan(36°)=349.60 ft

step 2

Find the distance from the base of the tree to the base of the radio tower

Let

x -----> the distance from the base of the tree to the base of the radio tower  

we know that

tan(62°)=254/x

x=254/tan(62°)=135.05 ft

step 3

Find the distance from the base of the building to the base of the tree

Adds the distances

349.60 ft+135.05 ft=484.65 ft

Round to the nearest foot

484.65 ft=485 ft

The final distance is approximately 485 feet.

Calculating the Distance from the Building to the Tree

To determine the distance from the base of the building to the base of the tree given the angles of elevation to the top of the radio tower, we can use trigonometry.

Let the height of the radio tower be 254 feet. Assume the distance from the base of the building to the base of the tower is x feet, and the distance from the base of the tree to the base of the tower is y feet.

Step-by-Step Solution:

Using the angle of elevation from the building, 36°, we can write:

tan(36°) = 254 ÷ x

Solving for x: x = 254 / tan(36°)

Using the angle of elevation from the tree, 62°, we can write:

tan(62°) = 254 ÷ y

Solving for y: y = 254 / tan(62°)

Calculate the values:

tan(36°) ≈ 0.7265

x = 254 / 0.7265 ≈ 349.6 feet.

tan(62°) ≈ 1.8807

y = 254 ÷ 1.8807 ≈ 135.1 feet.

The total distance from the base of the building to the base of the tree is x + y:

Total distance = 349.6 + 135.1 ≈ 485 feet.

Thus, the distance from the base of the building to the base of the tree is approximately 485 feet.

[tex]A = 301.59\ cm^2[/tex] or [tex]A=96\pi\ cm^2[/tex]

Step-by-step explanation:

The lateral area of a cylinder is calculated by the following formula

[tex]A = 2\pi r * h.[/tex]

Where r is the radius of the right cylinder and h is the height

In this case we know that the diameter d of the cylinder is

[tex]d=2r\\\\r=\frac{d}{2}\\\\r=\frac{12}{2}\\\\r=6\ cm[/tex]

[tex]h=8\ cm[/tex]

Therefore the lateral area is:

[tex]A = 2\pi*6 * 8.[/tex]

[tex]A = 96\pi[/tex]

[tex]A = 301.59\ cm^2[/tex]

Answer:

The lateral area of a right cylinder = 96π cm²

Step-by-step explanation:

Points to remember

The lateral area of a right cylinder  = 2πrh

Where r - Radius of cone and

h - Height of cone

To find the lateral surface area

Here diameter d = 12 cm

then radius r = d/2 = 12/2 = 6 cm

And h = 8 cm

Lateral surface area =  2πrh

= 2 * π *6 * 8 = 96π cm²

Therefore the lateral area of a right cylinder = 96π cm²

Answer:

Choice A. P = I² · R where

Step-by-step explanation:

Electrical power is the rate at which the electrical force does work. So what is electrical work? That's the work [tex]W[/tex] that the electrical force do when it moves charges [tex]Q[/tex] across a potential difference [tex]V[/tex]:

W = [tex]V\cdot Q[/tex].

The power is the rate at which the electrical force do the work:

[tex]\displaystyle P = \frac{W}{t} = V \cdot \frac{Q}{t}[/tex].

On the other hand, current [tex]I[/tex] is the charge through a cross-section of the circuit in unit time. By the definition of current:

[tex]\displaystyle\frac{Q}{t} = I[/tex].

[tex]\displaystyle P =V \cdot \frac{Q}{t} = V\cdot I[/tex].

Consider Ohm's Law:

[tex]V = I \cdot R[/tex].

Therefore

[tex]\displaystyle P = V\cdot I = (I \cdot R) \cdot I = I^{2}\cdot R[/tex].

Choice-A is one of several useful, correct formulas for electrical power.  It's true in AC circuits as well as DC ones.

Step-by-step explanation:

We need to drag the tiles and place them in boxes to form the correct pairs.

The given options are:-

1) [tex]9x^{2}+3x-20[/tex]

2) [tex](4x-3y)^{2}[/tex]

3) [tex](3x+5)(3x-4)[/tex]

4)[tex](3x+2)(9x^{2} -6x+4)[/tex]

First we simplify the all given factor and then compare with provided options

2) [tex](4x-3y)^{2}[/tex]

=[tex]16x^{2}+9y^{2}-24xy[/tex]

3) [tex](3x+5)(3x-4)[/tex]

[tex]9x^{2}-12x+15x-20[/tex]

[tex]9x^{2}+3x-20[/tex]

Here we can see equation (3) match with (1)

so, [tex]9x^{2}+3x-20=(3x+5)(3x-4)[/tex]

Hence, the correct match is shown in figure-1

The expressions that are equivalent should be matched as follows;

9x² + 3x - 20 ↔ (3x + 5)(3x - 4)

In order to match the equivalent expressions, we would have to either expand or factor each of the given expressions as follows;

9x² + 3x - 20

By applying the sum-product pattern, we have:

9x² + 15x - 12x - 20

By writing the common factor from the two pairs, we have:

(9x² + 15x) + (-12x - 20)

3x(3x + 5) - 4(3x + 5)

(3x + 5)(3x - 4)

Next, we would expand the expression (4x - 3y)²;

(4x - 3y)(4x - 3y)

16x² - 12xy - 12xy + 9y²

16x² - 24xy + 9y²

Answer:

The first blank is "y", the second blank is "x", and the third blank is 1:3.

Answer: I got A. 768 as the answer

Answer:

The value of y when x = 5 and z = 16 is 272

Step-by-step explanation:

* Lets Talk about the direct variation

- y is varies jointly (directly) as x and z, that means there are direct

  relation between y , x and z

- y increases if x increases or z increases

∴ y ∝ x × z

- To change this relation to equation we use a constant k

∴ y = k (x) (z), where k is the constant of variation

- To find the value of k we substitute the values of x , y and z in

  the equation above

∵ y = 136 when x = 5 and z = 8

∴ 136 = k × 5 × 8

∴ 136 = 40 k ⇒ divide both sides by 40

∴ k = 3.4

- Substitute this value in the equation

∴ y = 3.4 (x) (z)

∵ x = 5 , z = 16

∴ y = 3.4 (5) (16) = 272

∴ The value of y when x = 5 and z = 16 is 272

Answer:

The correct answer is B.

Step-by-step explanation:

If y varies jointly as x and z, then we can write the join variation equation.

[tex]y=kxz[/tex], where 'k' is the constant of proportionality.

If y = 136 when x = 5 and z = 8,then

[tex]136=k(5)(8)[/tex],

[tex]\implies 136=40k[/tex]

[tex]\implies \frac{136}{40}=k[/tex]

[tex]\implies \frac{17}{5}=k[/tex].

The variation equation now becomes:

[tex]y=\frac{17}{5}xz[/tex]

when x = 5 and z = 16, then

[tex]y=\frac{17}{5}(5)(16)[/tex]

[tex]y=17(16)[/tex]

[tex]y=272[/tex]

The correct answer is B.
