Step-by-step explanation:

We want to  confirm which of the given statement is true about the graph.

A) the amount of profit after the first year was around $0

-----------false

From the given graph, the amount of profit after year was far more $0. So the statement above is false.

B) The amount of profit increases about $10,000 each year ------------true

From the line of best fit shown in the graph, the amount of profit increases each year  by approximately $10,000.

C) the amount of profit decrease about $10,000 each year ------------ False

From the line of best fit on the graph, we can observe that the amount of profit does not decrease. It rather increases every year.

D) the amount of profit after the first year was around $30,000 ------------true

From the given graph, the  amount of  profit after the  first year is approximately $30,000.

So, the statement is true.

E) the amount of profit after 10 years is approximately $120,000  --------- true

At the year 10 on the graph , the  corresponding amount of profit is $120,000.

Length of the hypotenuse = 3√5 units

Step-by-step explanation:

Given:

Right triangle sides

a = 3

b = 6

Find:

Length of the hypotenuse

Computation:

Length of the hypotenuse = √a² + b²

Length of the hypotenuse = √3² + 6²

Length of the hypotenuse = √9 + 36

Length of the hypotenuse = √45

Length of the hypotenuse = 3√5 units

y+2 = -5(x-2)

Step-by-step explanation:

The point slope form of a line is

y- y1 = m(x-x1)  where m is the slope and (x1,y1) is a point on the line

y - -2 = -5(x-2)

y+2 = -5(x-2)

x=3

Step-by-step explanation:

Final Answer:

x = 3

Solution:

equation: -2x + 17 = 11

Step 1: subtract 17 in both sides

-2x + 17 = 11

-2x + 17 - 17 = 11 - 17

-2x = 11 - 7 (solve for -2x: 11 - 7)

-2x = -6

Step 2:  divide -2 in both sides then solve for x.

-2x = -6

 -2x        -6

Answer:

208

Step-by-step explanation:

Given that;

Given that;

y= a(1 - b)^t

Where;

wherein y is the final amount, a is the original amount, b is the decay factor, and x is the amount of time that has passed.

To obtain the constant b,

y= ae^-bt

Substituting values;

1000 = 3000 e^-b(50)

1000/3000 = e^b(50)

0.33 = e^b-(50)

ln (0.33) = ln(e^b(-50))

-1.1 = -50b

b= 1.1/50

b= 0.022

After two hours or 120 minutes;

y= 3000(1 - 0.022)^120

y= 207.8661772

y= 208

Answer:

the answer is -8

Step-by-step explanation:

Well, first you have to make an equation for what x equals, if that makes sense. So you take the x-y=6 and add y on both sides to get x=(y+6). Then you plug that.

Answer:

The measure of angle E is:

m∠E = 80°

Step-by-step explanation:

Given

The triangle ΔDEF

It is stated that DE=EF and G is the midpoint of EF.

It means the midpoint G has converted the triangle into two equal right-angles triangles ΔDEG and ΔDFG with the right-angle at G.

Given

m∠GDE = 10°

As the right-angle triangle, ΔDEG lies at the right-angle G.

So, m∠DGE = 90°

as

m∠GDE = 10°

m∠DGE = 90°

m∠E = ?

We know that the sum of angles of a triangle is 180°.

m∠GDE + m∠DGE  + m∠E = 180°

10° + 90° + m∠E = 180°

100 + m∠E = 180°

m∠E = 180° - 100

m∠E = 80°

Therefore,

The measure of angle E is: m∠E = 80°

Answer:

Marked down means the price has decreased by 20% so 100%-20%=80%

The suit is now 80% of its original price of 270.

So 270×(80/100)= 216

The selling price of the suit will be equal to $216.

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that a $270 suit is marked down by 20%. The selling price will be calculated as,

Marked down means the price has decreased by 20%,

100%-20%=80%

The suit is now 80% of its original price of 270.

Answer:

10 Gallons of water will weigh 1.2 pounds.

Step-by-step explanation:

Each gallon weighs 0.12 pounds, I got this answer from dividing 3 by 25 to see how much one gallon weighs. So if we multiply the weight of one gallon by 10, 0.12*10, then we will find out the weight of ten gallons.

I hope this helped you!! You can ask questions any question you may have, if needed, and I will answer them :)

10 Gallons of water will weigh 1.2 pounds.

Here, we have,

given that,

Morgan know that 3 gallons of water weigh 25 pounds.

now, we need to find how much do 10 gallons weigh.

so, we get,

3 gallons of water weigh 25 pounds.

so, to see how much one gallon weighs we divide 3 by 25 .

i.e. 3/25 = 0.12

Each gallon weighs 0.12 pounds,  

So if we multiply the weight of one gallon by 10,

i.e. 0.12*10, then we will find out the weight of ten gallons.

so, we get,

10 gallons weigh = 0.12*10 = 1.2 pounds.

Answer:

The angle would be acute

Step-by-step explanation:

The angle that this ladder would make with the ground is equal to 63.64°.

In order to determine the angle that this ladder would make with the ground, we would apply Cosine trigonometric. Mathematically, this is given by this expression:

Cosθ = Adj/Hyp

Substituting the given parameters into the formula, we have;

Cosθ = 8/18

Cosθ = 0.4444

θ = cos⁻¹ (0.4444)

θ = 63.64°

Step-by-step explanation:

According to Question , Yoshua borrowed $8,000 from his credit union over 9 months. He pays a simple interest of 9%. And we are required to find the total amount of money he will owe the bank .

So , we know the formula of Simple Interest as ,

[tex]\qquad\boxed{\red{\bf SI =\dfrac{P\times R\times T}{100}}}[/tex]

As ,per the data in Question ,

[tex]\implies SI = =\dfrac{P\times R\times T}{100} \\\\\implies SI =\dfrac{\$ 8000 \times \dfrac{9}{12}\times 9 }{100} \\\\\implies SI = \dfrac{\$ 8000 \times 9 \times 9 }{12\times 100 }\\\\\boxed{\pink{\bf \implies Simple\: Interst = \$ 540 }}[/tex]

Hence the Simple Interest is $ 540.

And , we know that Amount is ,

[tex]\qquad\boxed{\red{\bf Amount = SI + Principal}}[/tex]

[tex]\implies Amount = Principal + SI \\\\ \implies Amount = \$ 8000 + \$ 540 \\\\\boxed{\orange{\bf \implies Amount= \$ 8540 }}[/tex]

Hence he will owe $ 85400.
