When asked to draw a triangle with two 45 angles and a side length of 8 cm, Diego drew this triangle.

Do you agree with Diego’s answer?

Is there a different triangle Diego could have drawn that would answer the question? Explain or show your reasoning

Answers

The triangle is an equilateral triangle, therefore, Diego didn't draw the right triangle.

What is a triangle?

A triangle simply means a polygon that has three edges and vertices. It's a shape in geometry.

In this case, I don't agree with Diego's drawing as the triangle is an equilateral triangle and this means that each side is 60° and not 45° as illustrated.

Nora was offered a job that paid a salary of
$

,
000
$40,000 in its first year. The salary was set to increase by 3% per year every year. If Nora worked at the job for 21 years, what was the total amount of money earned over the 21 years, to the nearest whole number?

Answers

The growth in Nora's salary illustrates a geometric progression

The total amount earned over the 21 years is $1147059

How to determine the total earning?

The given parameters are:

Initial salary, a = 40000

Rate, r = 1 + 3% = 1.03

Number of years = 21

The sum of n terms of a geometric progression is represented as:

Sn = a((r^n) - 1)/(r - 1)

So, we have:

S21 = 40000 * ((1.03^21) - 1)/(1.03 - 1)

Evaluate

S21 = 1147059

Hence, the total amount earned is $1147059

Answer: B. 8 3/4

Step-by-step explanation:

The amount of sand he needs would be equal to the volume of the sand box.

Since the sandbox is a rectangular prism, the volume if the length*width*height/depth.

We can plug in the values given.

Volume = 3.5 feet*5 feet * 0.5 feet

Volume = 8.75 feet^3 = 8 3/4 feet^3

Answer:

B. 8 3/4

Step-by-step explanation:

How do we find the volume of a rectangular prism?

  ❖ The volume of a rectangular prism can be found by using the formula

       length × width × height. We're given all the dimensions, so now we can

       solve for the volume

m<a = 3x+11 and m<b = 17x-91. The angles are supplementary. Find the value of x.​

Answers

Answer:

x = 13

Step-by-step explanation:

Supplementary means 180 degrees.

Since we are finding the supplement, we are going to add both angles together and solve for x.

3x + 11 + 17x - 91 = 180

~Combine like terms

20x - 80 = 180

~Add 80 to both sides

20x = 260

~Divide 20 to both sides

x = 13

Best of Luck!

Answer:

Since the measure of both angles are supplementary, its easy to form the equation.

3x+11+17x-91 = 180

20x-80 = 180

20x = 100

x = 5

m<a = 3x+11

= 3(5)+11

= 15+11

= 26

m<b = 17x-91

= 17(5)-91

= 85-91

= -6

Answers

Lewis has to pay $260 more to have his electricity and cable turned on because of his bankruptcy.

What is bankruptcy?

Bankruptcy is a legal proceeding involving a person or business that is unable to repay its outstanding debts.

Had Lewis not filed bankruptcy, he would have paid = 90+50+65+75

He would have paid (let us say amount A)= $280

After filing for bankruptcy he has to pay = 205+75+150+110

He has to pay (let us say amount B)= $540

Difference between amount A and amount B = $540-$280

Difference between amount A and amount B = $260

Therefore, Lewis has to pay $260 more to have his electricity and cable turned on because of his bankruptcy.

Answer:

Rs 800

Step-by-step explanation:

Selling Price =Rs640

Loss=20%

Let the cost price of the watch be Rs x.

SP=CP-20%of CP
