Answer:

  7 square inches

Step-by-step explanation:

We take the "3 in" dimension at the left to be the length of the line segment below the 1" square, so the height of the right triangle is 3+1 = 4 in.

The triangle area is ...

  A = 1/2bh

  A = 1/2(3 in)(4 in) = 6 in²

The square area is ...

  A = s²

  A = (1 in)² = 1 in²

Then the total area of the figure is ...

  1 in² + 6 in² = 7 in²

y = (x - 2)² - 9

Step-by-step explanation:

Using the method of completing the square

add/ subtract ( half the coefficient of the x- term)² to x² - 4x

y = x² + 2(- 2)x + 4 - 4 - 5

y = (x - 2)² - 9

Answer:

78.5 cm^2

Step-by-step explanation:

the circle's diameter is 10cm --> its radius is 5cm

the area of the circle is 5^2 x 3.14 = 78.5cm^2

The area of circle is [tex]25\pi[/tex] square units.

What is the formula for area of circle?

The area of a circle is given by [tex]\pi r^{2}[/tex] where r is the radius of the circle.

The given circle is inscribed in a square. so, the side length of the square will be the diameter d of the circle.

So, d=10.

Divide diameter d by 2 to get the radius of the circle.

[tex]r=\frac{10}{2}[/tex]

So, r=5.

Substitute 5 for r into the formula of area of circle.

[tex]\pi \cdot5^{2}=25 \pi[/tex]

Therefore, the area of circle is [tex]25\pi[/tex] square units.

Answer:

87.96 square inches

Step-by-step explanation:

The soup can is a cylinder, and we can find how many square inches the label will take up by finding the lateral surface area

Use the formula, LA = 2[tex]\pi[/tex]rh

The diameter is 4 inches, so the radius is 2 inches

Plug in the radius and height into the formula, and solve:

LA = 2[tex]\pi[/tex]rh

LA = 2[tex]\pi[/tex](2)(7)

LA = 28[tex]\pi[/tex]

= 87.96

So, the label will take up approximately 87.96 square inches

Answer: 54°

Step-by-step explanation:

We can see that this triangle is a right triangle (look at the little square in the triangle's corner-- that tells us that it's a right angle). A right angle is 90°

A triangle always has 180° in total.

So, we can add 90° and 36° and subtract the sum from 180°

180° - (90° + 36°) = 180° - 126° = 54°

Answer:

x = 54

Step-by-step explanation:

One of the properties for any triangle is that the sum of angles in the triangle will always equal 180 degrees. As one can see, one of the angles is (90) degrees, this is indicated by the box around the angle. It is given that one of the other angles is (36) degrees. One can call the unknown angle (x) and form an equation. Substitute in the given values and solve for (x).

(90) + (36) + (x) = 180

Simplify,

126 + x = 180

Inverse operations,

126 + x = 180

-126       -126

x = 54

Sarah's scale is reasonable.

A scale drawing is a smaller diagram in terms of dimensions of an original image / building / object. The scale drawing is usually reduced at a constant dimension.

The first step is to determine the how larger the paper is in terms of the painting.

48 / 12 = 4

120 / 24 = 5

This makes her scale of 1 in to 4 in reasonable.

Answer:

Second option: 5E 10 = 5*10^(10) galaxies.

Step-by-step explanation:

The exponential notation is used as:

AE N

This is equal to:

A*10^(N)

And we need to add N zeros to the right of A.

While if we had:

AE - N

A*10^(-N)

We need to add N - 1 zeros at the left of A.

Now we have the number:

50,000,000,000

Let's count the number of zeros at the right of the 5, we have 10 zeros.

Then we would write this as:

5*10^(10)

OR

5E 10

Then the correct option is the second one.

Answer:

c = 8.6

Step-by-step explanation:

a² + b² = c²

The length in x is 7

The rise in y is 5

7² + 5² = c²

49 + 25 = c²

74 = c²

Take the square root of both sides

c = 8.602325267

Rounded

c = 8.6
