Calculate the approximate area of the shape to the nearest cm2.

Answers

This is very simple. So you use two formulas:

Rectangle: Length • Width

Semicircle: Area = [tex]\frac{\pi r^2}{2}[/tex]

With that, you do 0.8 ÷ 2 = 0.4 because we will be using radius. When solved, you get 0.2512... But for this problem, I will be rounding everything to the nearest hundredths.

Area of semicircle: ≈ 0.25

Now we solve for the rectangle. That is very easy. Just multiply 0.75 • 0.8 and you get 0.6

For this problem, I'm not sure why they make you round to the nearest centimeter, but if you do, you get 1 cm. Otherwise,

Round to nearest tenth: 0.9

Round to nearest hundredths: 0.85

Use the fact that √7 is a solution to the equation x² = 7 to find a decimal approximation of √7 whose square is between 6.9 and 7.1

Answers

Wouldn’t it be 49? I’m not 100% sure because the question is a little confusing. I just found it by squaring seven because the square root of 49 is 7, and 7 is right between 6.9 and 7.1. Sorry if I’m wrong :)

The decimal whose square is 7.0008 is  2.6459.

What is a decimal ?

A decimal separates the whole part and the fractional part of a given number.A decimal can also be represented as a fraction.

According to the given question √7 is a solution to the equation x² = 7.

The decimal approximation of √7 is 2.6458.

Now to find the decimal approximation of √7 whose square is between 6.9 and 7.1 we will take some value which is just more than 2.6458.

Lets take 2.6459 by squaring it we get 7.0008 which is in between 6.9 and 7.1.

Step-by-step explanation:

Since the y-value decreases at the same rate as the x-value and has a negative slope, the expression that properly answers this question is y = -1x. Another thing taken into consideration is the y-intercept, which is zero, so you don't need to add anything to the initial equation.

Answers

g= -16x^2 +16x + 14 (going based on the picture, not your typing)

First solve the first equation for z:
g-14=4z
(g-14)/4=z

Then plug that in for z in the second equation and solve for g:
(g-14)/4 = 4x-4x^2
g-14=16x-16x^2

g= -16x^2 +16x + 14

Answer:

480 in3

Step-by-step explanation:

So the first thing I looked at was how to find the volume of a 3-dimensional square. Why do we have to do this? Well, we can see that the shape is made up of 3 different types of 3-dimensional cubes so to find the answer all we have to do is figure out the volume for each separate cube and add them all together.

So, to find the volume of a cube we have to multiply the area (length x width) by the height of each cube.

Let's start with the largest cube so we would multiply 5 x 12 x 4 which equals v = 240

Now let us do the second to largest by multiplying 8 x 5 x 4 = which equals    v = 160

Finally, on to the smallest cube, 4 x 4 x 5 =

v = 80

So now if we add 240 + 160 + 80 that will give us 480

So the answer is 480 in3

Hope this is correct I was a little confused while I was figuring it out :0 Sorry if it is wrong :(

How many four-digit numbers can be created using the digits 0-9? Note: A number cannot be repeated for different digits.

10,000
5,040
3,024
6,561

Answers

6,561 is the right answer but good luck

5,040 four-digit numbers can be created using the digits (0-9).

Option B is the correct answer.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

There are 10 options for the first digit (0-9).

9 options for the second digit (since one digit is already used).

8 options for the third digit.

7 options for the fourth digit.

Therefore,

The total number of four-digit numbers that can be created is:

10 x 9 x 8 x 7 = 5,040

Thus,

5,040 four-digit numbers can be created using the digits (0-9).
