If 2 pints = 1 quart, how many pints are in a 26-quart container
Answer:
52 pints
Step-by-step explanation:
Given;
2 pints = 1 quart
To Find;
How many pints are in a 26-quart container
Solve;
Since 2 pints = 1 quart
Then the Formula = divide the volume value by 2
The equation for 2 pints = 1 quart is 2 ÷ x = 1
which x = 2.
Thus, the equation for 26 quart container = how many pints =
x ÷ 2 = 26
Divide/Multiply sides by 2
2x/2 = 26 * 2
Simplify
x = 52
Hence, there are 52 pints in a 26 quart container

[] The equation on the left, 292 [tex]\frac{1}{2}[/tex] = 18 * 6 [tex]\frac{1}{2}[/tex] * h
-> Volume is length times width times height. When we plug in all the values we have to solve for h (height) we get this equation.
[] The height is 2.5 inches
-> We will solve the equation above.
-> Multiply 18 by 6 and a half = 117
-> Divide 292 and a half by 117 = 2.5
-> The height is 2.5 inches or 2 [tex]\frac{1}{2}[/tex]inches
292 [tex]\frac{1}{2}[/tex] = 18 * 6 [tex]\frac{1}{2}[/tex] * h
292 [tex]\frac{1}{2}[/tex] = 117h
[tex]\frac{292 \frac{1}{2} }{117}[/tex]= [tex]\frac{117h}{117}[/tex]
2.5 = 1h
h = 2.5 inches

The standard form is ( -8m⁵+10m⁴+9m³-16m²+15m ).
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.
The expression will be solved as:-
E = ( 3m² - m )( 4m³ + m - 5 )
E = -8m⁵ - 2m⁴ + 10m³ - 15 m² - 4m³ - m² + 5m
E = ( -8m⁵+10m⁴+9m³-16m²+15m ).
Therefore, the standard form will be ( -8m⁵+10m⁴+9m³-16m²+15m ).

You lose track of how many 2-point baskets and 3-point baskets a team makes in a basketball game. The team misses all the 1-point baskets and still scores 54 points. The equation 2x+3y=54$ models the total points scored, where x is the number of 2-point baskets made and y is the number of 3-point baskets made. a. Find and interpret the intercepts.
Answer:
x-intercept: 27, the number of 2-pointers if no 3-pointersy-intercept: 18, the number of 3-pointers if no 2-pointersStep-by-step explanation:
Each intercept is found by setting the other variable to zero and solving for the variable value of interest.
2x +3y = 54
x-intercept:
2x = 54
x = 27
y-intercept:
3y = 54
y = 18
__
By definition, the intercept values are the values that satisfy the equation when the other variable is zero.
x-intercept: To score 54 points, the team would have to make 27 2-point baskets if no 3-point baskets were made.
y-intercept: To score 54 points, the team would have to make 18 3-point baskets if no 2-point baskets were made.
