Answer:

Option 'B' is correct answer

Answer:

[tex]2x[/tex] is the expression we determine after following the steps 'Start with x and double it'.

Step-by-step explanation:

As we have to determine the expression based on a mentioned series of steps.

The series of steps:

As the double value of x would be 2x, therefore, the required expression would be: 2x

Therefore, [tex]2x[/tex] is the expression we determine after following the steps 'Start with x and double it'.

Answer: 243.6

Step-by-step explanation:

For us to solve the question and round off 243.583 to the nearest tenth. First, we need to look at the number beside the tenth number which is 8.

Since 8 is more than 4, we simply add 1 to the tenth number which implies that we add 1 to the number in tenth place which is 5. Adding one means the number change to 6. Therefore, rounding 243.583 to the nearest tenth will be 243.6.

Answer:

8 cm

Step-by-step explanation:

Given that:

Side = 5cm

Altitude = height = 8cm

Diagonal 1 = 10cm

Diagonal 2 = d

Area of rhombus = base * height = 0.5 * (diagonal 1 * diagonal 2)

5 * 8 = 0.5 * (10 * d)

40 = 5d

Divide both sides by 5

40/5 = 5d / 5

8 = d

Length of other diagonal = 8cm

Answer: It’s 3/2(cos(75) + isin(75))

Step-by-step explanation: you multiply 3 and 1/2 first. then add 60 and 15! (edge)

Answer:

A

Step-by-step explanation:

3/2[cos(75º) + i sin (75º)]

Answer:

Step-by-step explanation:

when the line goes down like that you know the slope's going to be negative. so now you do rise/run. down two over 1, down two over 1. so your slope is -2

Answer:

-2 is the slope

Step-by-step explanation:

Answer:

y = 2x - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = A(4, 7) and (x₂, y₂ ) = B(2, 3)

m =  =  = 2, thus

y = 2x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation.

Using B(2, 3), then

3 = 4 + c ⇒ c = 3 - 4 = - 1

y = 2x - 1 ← equation of line

Answer:

Answer 3 (y=55x+20)

Step-by-step explanation:

The question says 55 each, meaning we don't know how much so u put x after 55. 20 is the additional cost that you pay only once.

Answer:

Step-by-step explanation:

Step one:

We are told that they need at least 50 total rooms.

Joe has paid for 16 rooms since Joe can only reserve rooms in block, and a block has 8 rooms, then Joe has paid for 2 blocks.

There is a deficit of 50-16= 34rooms

Required

The Number of blocks Joe need to reserve in addition is 34/8

=4.25

The blocks can not be in decimal, so we need to approximate, which is 5 blocks

Therefore Joe is going to reserve 5*8= 40 rooms

He is going to pay 40*900= $36000 for the reservation

Answer:

The answer is 20

Step-by-step explanation:

0.4 = 40%

0.4 * 50 = 20

Answer:per pound would cost 2.50 and for nine pounds it would cost 22 dollars and 50 cent

Step-by-step explanation:

750 divided by 3=250 just add your point were before five and 7.50 plus 7.50 equals 15 plus 7.50 equals 22.50

Answer:

The slope is 1

Step-by-step explanation:

Slope can be found using the expression [tex]\frac{y2-y1}{x2-x1}[/tex]

In this case,

y2 = 3

y1 = 1

x2 = 6

x1 = 4

[tex]\frac{3-1}{6-4}[/tex]  =  2/2 = 1

Answer:

4 dollars and 60 cents

Answer:

1 & 2 = Right Triangles

3 & 4 = Not Right Triangles

Step-by-step explanation:

Solved Using Pythagorean Theorem:

1) [tex]9^{2} + 12^{2}[/tex] = 225

[tex]15^{2}[/tex] = 225

2) [tex]15^{2} + 36^{2}[/tex] = 1521

[tex]39^{2}[/tex] = 1521

3) [tex]10^{2} + 26^{2}[/tex] = 776

[tex]28^{2}[/tex] = 784

4) [tex]10^{2} + 12^{2}[/tex] = 244

[tex]16^{2}[/tex] = 256

Answer: C. 4x is a term in 4x - 5

Step-by-step explanation: 4 is a coefficient due to being combined with x. But together, it is called a term. 5 can not be a coefficient due to it being away from x. I hope this helped.

Answer:

A) 565.2

Step-by-step explanation:

Get the diameter (18*2=36) then multiply 36 by 3.14. You will then get 113.04. Multiply that by 5 and you get your answer 565.2
