Answer 1

Answer:

60 squared cm

Step-by-step explanation:

If half of the top of the shape is 3, that means the whole top is 6.

6 x 10 = 60

Area = Length x Width

Answer 2
So, 3cm is only half so I think it would have to be changed to 6cm to be the full width. Then, is length X width, so 6 X 10 meaning it would be 60cm^2, I think.

An equilateral triangle with side length 9 cm is shown in the diagram, work out the area of the triangle.
Give your answer rounded to 1 DP.

Answers

Question:-

Find the area of an equilateral triangle with side length = 9cm correct upto one decimal place.

_______________________________________________

Solution:-

In an equilateral triangle all sides are equal.

Let s = side length = 9 cm

Then, area of equilateral triangle is given as:

A = (√3/4)s²

Putting the value of s here,

A = (√3/4) * (9 cm)²

=> A = (√3/4) * 81 cm²

=> A = √3 * 20.25 cm²

We know that, √3 = 1.732

=> A = 1.732 * 20.25 cm²

=> A = 35.073 cm²

Rounding to one decimal place,

=> A = 35.1 cm²

_______________________________________________

The answer is 35.1 cm².

Hope this helps; have a great day!

write an expression equivalent to `b+b+b+b+b` that is a product of a coefficient and a variable.

Answers

Answer:

b^5

Step-by-step explanation:

The expression `b+b+b+b+b` is equivalent to 5b, which is a product of a coefficient and a variable.

What is an expression?

It is defined as the combination of constants and variables with mathematical operators.

We have:

= b+b+b+b+b

Here, b is the variable after adding b five times we get:

= 5b

5 is the coefficient and b is a variable.

Thus, the expression `b+b+b+b+b` is equivalent to 5b, which is a product of a coefficient and a variable.

When solving a system of equations, Jared found y = x + 10 for one equation and substituted x + 10 for y in the other equation. Nicole found x = y – 10 for the same equation and substituted y – 10 for x in the other equation. Who is correct? Explain.

Answers

Answer:

Jared and Nicole are correct.

Step-by-step explanation:

You can solve for either variable and use the equivalent expression to create a one-variable equation. They manipulated the equation right. They can either write the equation as y as a function of x then substitute it to the y in the other equation and solve for x. For both solutions, they'll still get the same answers.

x=28 (small angle)

28+34=62 (big angle)

28+62 =90
