Answer:
15 miles per gallon
Step-by-step explanation:
Divide miles travelled by gallons used, that is
90 ÷ 6 = 15 miles per gallon
The rate of the truck is 15 miles per gallon.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that a truck travels 90 miles on 6 gallons of gas. The rate of truck will be calculated as:-
Divide miles travelled by gallons used, that is
Rate = 90 ÷ 6
Rate = 15 miles per gallon
Hence, the rateis 15 miles per gallon.

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

. Larry solved this equation. 3(2-3)= x Which representation could Larry have used to solve this equation?
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
The measure of an angle is 39°. What is the measure of its complementary angle?
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:

HELP!!! Will give brainliest:) What shapes have all sides that are congruent?
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.

Determine if the two triangles are congruent. If yes, which theorem proves their congruence?
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.

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? * answer to this problem hat is what i need
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
