Which expression can be used to convert 22 Australian dollars to US dollars

Answer:

45 bricks

Step-by-step explanation:

- With the knowledge of the 11,700 in^3 being used. We would need to have the measurements of the brick in that form as well. So in order to find the volume, we must multiply all sides. (13*5*4) = 260 in^3

- Now we have both numbers, we can just divide 11,700 by 260. This will give us 45. Meaning that 45 bricks are made.

-7+8x7

Use PEMDAS

first multiply 8 and 7 =56

then add -7 and +56

56-7 =49

Answer:

(B)

Step-by-step explanation:

We have the equation:

[tex]y-3=-2(x+5)[/tex]

Convert into Slope Intercept Form:

[tex]y-3=-2(x+5)[/tex]

[tex]-2*x=-2x\\-2*5 = -10[/tex]

[tex]y-3=-2x-10[/tex]

[tex]y-3+3=-2x-10+3\\\boxed {y=-2x-7}[/tex]

Slope-intercept form is [tex]y=mx+b[/tex].

Since '-7' is in the 'b spot', the y-intercept of the line would be -7, or option B.

Option B should be the correct answer.

Answer:

y intercept is -7

Step-by-step explanation:

y - 3 = -2 (x+5)

This is point slope form

We want to get this to slope intercept form

y=mx+b  where m is the slope and b is the y intercept

Distribute

y-3 = -2x-10

Add 3 to each side

y-3+3 = -2x-10+3

y = -2x-7

The slope is -2 and the y intercept is -7

Answer:

Number of students in each van = 18

Number of students in each bus = 53

Step-by-step explanation:

Given: The senior class at High School A rented and filled 2 vans  and 7 buses with 407 students.

High School B rented and filled 1 van and 7 buses with  389 students.

Also, every van and the van had the same number of students in it.

Solution:

Let x denotes number of students in each van and y denotes number of students in each bus.

According to the given information,

[tex]2x+7y=407\,\,\,(i)\\x+7y=389\,\,\, (ii)[/tex]

From (ii), put [tex]x=389-7y[/tex] in (i)

[tex]2(389-7y)+7y=407[/tex]

[tex]778-14y+7y=407\\778-407=7y\\7y=371\\y=\frac{371}{7}=53[/tex]

Put [tex]y=53[/tex] in [tex]x=389-7y[/tex]

[tex]x=389-7(53)\\=389-371\\=18[/tex]

Number of students in each van = 18

Number of students in each bus = 53

Step-by-step explanation:

Answer:

Campers: 7, 14, 28, 42

Adults: 1,2,5,30

Step-by-step explanation:

The tabular representation of the ratio of campers to adults in the summer camp is given as follows -

CAMPERS :  7          14        21          28      . . . .    7n

ADULTS :     1           2          3           4        . . . .     n

We have a summer camp in which the ratio of campers to adults is kept equivalent to 7:1 .

We have to complete the table using the equivalent ratios.

To find the equivalent ratios of a : b, follow the simple rule -

[tex]a:b=\frac{a}{b}=\frac{a\times2}{b\times2} =\frac{a\times3}{b\times3} =\frac{a\times4}{b\times4} = ... =\frac{a\times n}{b\times n}[/tex]

In the question given -

[tex]a:b=\frac{7}{1}=\frac{7\times2}{1\times2} =\frac{7\times3}{1\times3} =\frac{7\times4}{1\times4} = ... =\frac{7\times n}{n\times n}[/tex]

Hence, we can write the equivalent ratios in the form of tables -

CAMPERS :  7          14        21          28      . . . .    7n

ADULTS :     1           2          3           4        . . . .     n

Answer:

(3x + 4)

Step-by-step explanation:

9x²+27x+20 can be factored out to (3x + 4)(3x + 5)

Answer:35

Simplifying

5(x + 20) = 7x + 30

Reorder the terms:

5(20 + x) = 7x + 30

(20 * 5 + x * 5) = 7x + 30

(100 + 5x) = 7x + 30

Reorder the terms:

100 + 5x = 30 + 7x

Solving

100 + 5x = 30 + 7x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-7x' to each side of the equation.

100 + 5x + -7x = 30 + 7x + -7x

Combine like terms: 5x + -7x = -2x

100 + -2x = 30 + 7x + -7x

Combine like terms: 7x + -7x = 0

100 + -2x = 30 + 0

100 + -2x = 30

Add '-100' to each side of the equation.

100 + -100 + -2x = 30 + -100

Combine like terms: 100 + -100 = 0

0 + -2x = 30 + -100

-2x = 30 + -100

Combine like terms: 30 + -100 = -70

-2x = -70

Divide each side by '-2'.

x = 35

Simplifying

x = 35

Hope it helps. Please tell me if im correct

Answer:

35

Step-by-step explanation:

5 * X= 5x

5* 20=100

these are for the ones inside the pararenthesis

so....

5x + 100= 7x+30

subtract 30 from both sides

5x+100-30= 7x-30-30

5x+70= 7x

now we need the variable on one side

so we subtract 5x on both sides

5x-5x+70= 7x-5x

70= 2x

now we divide by 2 on both to isolate the variable

70/2= 2/2

35=x

that's ur answer

hope this helped :D

Step-by-step explanation:

Answer:

length of string  ≈ 421  units (nearest whole number)

Step-by-step explanation:

Juliet is standing on the balcony 44 above the ground . The angle of depression is 6°. A string was held between Juliet and Romeo.

The illustration forms a right angle triangle. The hypotenuse of the triangle is the length of the string held by both star crossed lovers. The opposite side of the triangle is given as 44. Therefore,

using sin ratio

sin 6° = opposite/hypotenuse

sin 6° = 44/length of string

cross multiply

length of string sin 6° = 44

divide both sides by sin 6°

length of string = 44/sin 6°

length of string = 44/0.10452846326

length of string = 420.937978274

length of string  ≈ 421 units(nearest whole number)

Answer:

Zero of the function f(x) is x = 5

Step-by-step explanation:

Given function is f(x) = x² - 10x + 25

For zeros or x-intercepts of this function,

Put f(x) = 0

x²- 10x + 25 = 0

x² - 2(5)x + 5² = 0

(x - 5)² = 0 [Since, a² - 2ab + b² = (a - b)²]

x = 5

Therefore, x = 5 will be the zero of the given function.

Answer:

Length of x ⇒ ( About ) 11.5; Option C

Step-by-step explanation:

~ Let us plan this question step-by-step. We know that the line segment with length 13.1 is a radii to the circle, as well as a hypotenuse to a right triangle. Respectively the hypotenuse of another triangle is a hypotenuse as well. By radii ≅, these two part of these two triangles are ≅ ~

1. If these two parts are ≅, the triangle with leg x has a hypotenuse of 13.1 as well ( through ≅ ). This would mean that Pythagorean theorem is applicable for this triangle, as to solve for line segment x.

2. By Pythagorean Theorem ⇒

6.2^2 + x^2 = 13.1^2,

38.44 + x^2 = 171.61,

x^2 = 133.17

Length of x ⇒ ( About ) 11.5

Answer: 6 inches of chain will he have left after making the necklaces

Step-by-step explanation:

There is a missing information. The correct question is:

Tony needs 16-inch pieces of gold chain to make each of 3 necklaces. He has a piece of chain that is 4 1/2 feet long. How much chain will he have left after making the necklaces.

Solution

We would convert 4.5 feet to inches

1 foot = 12 inches

4.5 feet = 4.5 × 12 = 54 inches

Tony needs 16-inch pieces of gold chain to make each of 3 necklaces. It means that the number of the 16 inches pieces of gold chain that can be gotten to make each of 3 necklaces necklaces is 16 × 3 = 48

The length of chain left chain that will he have left after making the necklaces is

54 - 48 = 6 inches
