Answer:

7 1/2 quart of paint

Step-by-step explanation:

To get the correct color, Johan mixed 3 1/4 quart of white paint, 1 2/4 quart of blue paint, and 2 3/4 quart of green paint. How much paint did Johan make? *

The above question is solved as:

3 1/4 quart + 1 2/4 quart + 2 3/4 quart

Lowest common denominator = 4

3 + 1 + 2 + ( 1/4 + 2/4 + 3/4)

= 6 + ( 1 + 2 + 3/4)

=( 6 + 6/4) quart

= 6 + 1 2/4 quart

= 7 2/4 quart of paint

= 7 1/2 quart of paint

Therefore, Johan made 7 1/2 quart of paint

Answer:

51 degrees

Step-by-step explanation:

Complementary angles are two angles whose sum is (90degrees). If one is given an angle measure and needs to find its complementary angle, then all one has to do is subtract the given angle measure from (90degrees).

90 - 39 = 51

Answer:

45 cm

Step-by-step explanation:

Area of a triangle:

A = 1/2bh

b = 3 + 2 = 5

A = 1/2(5)(6)

A = 15

Area of a rectangle:

A = bh

A = 12*2.5

A = 30

Combined:

30 + 15 = 45

The sailboat has 2 right angle triangles and a rectangle

First lets find the area of the rectangle then each one of the triangles

Area of rectangle = Length × Height

Area of rectangle = 12 × 2.5

Area of rectangle = 30 cm²

Now lets find the area of triangle on the right,

Area of triangle = Height × base × [tex]\frac{1}{2}[/tex]

Area of triangle = 6 × 3 × [tex]\frac{1}{2}[/tex]

Area of triangle = 18 × [tex]\frac{1}{2}[/tex]

Area of triangle = [tex]\frac{18}{2}[/tex]

Area of triangle = 9 cm²

Now lets find the area of the triangle on the left,

Area of triangle = Height × base × [tex]\frac{1}{2}[/tex]

Area of triangle = 6 × 2 × [tex]\frac{1}{2}[/tex]

Area of triangle = 12 × [tex]\frac{1}{2}[/tex]

Area of triangle = [tex]\frac{12}{2}[/tex]

Area of triangle = 6 cm²

Now lets find the total area of the sailboat,

Total area = Area of rectangle + Area of triangle on the right + Area of triangle on the right

Total area = 30 + 9 + 6

Total area = 39 + 6

Total area = 65 cm²

Therefore the total area of the sailboat is 65 cm²

Answer:

x = -3

Step-by-step explanation:

Given the expression solved by Larry as;

3(2-3) = x

We are to find the equivalent expression x

Using the distributive law;

3(2) - 3(3) = x

6 - 9 = x

-3 = x

Swap

x = -3

Hence Larry could use the distributive law to solve the expression

Answer:

36

Step-by-step explanation:

The first step to solving this equation is multiplying. Multiply the numbers on the inside of the square root.

18 × 18 × 4 = 1296

Now, you are going to find the square root of 1296.

[tex]\sqrt{1296}[/tex] = 36

You now have your final answer.

I hope this makes sense and is easy to understand. Please let me know if you need any more help. Have a great day! :]

Answer:

Not congruent.

The Angle-Side-Side Postulate does not exist because an angle and two sides does not guarantee that two triangles are congruent. If two triangles have two congruent sides and a congruent non included angle, then triangles are NOT NECESSARILLY congruent.

Answer:

  [tex]\begin{cases}3x+12&\text{if }x>-4\\0&\text{if }x=-4\\-3x-12&\text{if }x<-4\end{cases}[/tex]

Step-by-step explanation:

The absolute value function negates its argument when its argument is negative. The expression 3x+12 will be negative when ...

  3x +12 < 0

  x +4 < 0

  x < -4 . . . . . makes the absolute value function change its argument's sign

Using this fact, we can divide the domain into intervals below -4, at -4, and above -4. The above answer shows the function value in each domain interval.

Answer:

A square has all sides congruent. SIDE A, B, C and D would be congruent in size to one another, and the angles would also be equal to one another. However, most any polygon can be drawn with all sides and angles equal. For instance, an equilateral triangle has all sides and all angles equal, and that is the definition of a polygon. Polygons with more sides are described as "regular" e.g., a stop sign or an equilateral octagon is also a shape that has all sides congruent. A rectangle, however, would not, since only two sides would be congruent to one another.
