Step-by-step explanation:
z = 24a - 2b
solve for a
Answer:
a= (Z + 2b)/24
Step-by-step explanation:
given:
Z = 24a - 2b
to solve for a, we will try to move "a" to one side of the equation and all other terms to the other side:
Z = 24a - 2b (add 2b to both sides)
Z + 2b = 24a -2b +2b
Z + 2b = 24a (switch sides)
24a = Z + 2b (divide both sides by 24)
a/24 = (Z + 2b)/24
a= (Z + 2b)/24
Una fábrica envasadora recibe diariamente distintos tipos de aceite en las siguientes cantidades: 195 l, 275 l, 315 l, 460 l y 525 l. Puesto que los aceites son diferentes, los envasarán en diferentes garrafas. Sin embargo, quieren utilizar el menor número posible de garrafas, que todas tengan la misma capacidad y que no sobre ni una gota de aceite.
Answer:
Se calcula el maximo comun divisor.
195/5 = 39
275/5 =55
315/5 =63
460/5= 92
525/5 =105
Se deben utilizar 354 garrafas
Step-by-step explanation:
Descomponemos cada número en factores primos.
Después, señalamos los factores comunes.
A continuación, en cada uno de los comunes, escogemos el factor con menor exponente.
Y por ultimo, multiplicamos los factores elegidos.

Machine A makes 12.75 ounces of popcorn in 3 minutes. Machine B makes 18 ounces of popcorn in 4 minutes.
If each machine makes popcorn for 10 minutes, will there be enough popcorn for eight 9-ounce bags?
A. Yes; Machine A and Machine B make 77.5 ounces in 10 minutes. 77.5 > 72, so there will be enough popcorn.
B. Yes; Machine A and Machine B make 87.5 ounces in 10 minutes. 87.5 > 72, so there will be enough popcorn.
C. No; Machine A and Machine B make 67.5 ounces in 10 minutes. 67.5 < 72, so there will not be enough popcorn.
D. No; Machine A and Machine B make 30.75 ounces in 10 minutes. 30.75 < 72, so there will not be enough popcorn.

A local restaurant serves breakfast. They use 124 cups of pancake mix every hour. It takes 114 cups of mix to make one pancake. The pancakes are all equal in size.
About how many pancakes can the restaurant make in two hours?
A 99 pancakes
B 198 pancakes
C 251 pancakes
D 310 pancakes
198 pancakes can the restaurant make in two hours.
What is Equation?Two or more expressions with an equal sign is called as Equation.
The restaurant can make 199 pancakes in two hours.
Given: Total number of cups of pancake mix used in 1 hour = 124
Mix required for each pancake 1 1/4=5/4.
Number of cups of pancake mix used in 2 hours = 2 x 124 = 248
Number of pancakes made = (Number of cups of pancake mix used in 2 hours ) ÷ (Mix required for each pancake )
=248÷5/4
=248×4/5
=198.4
Hence 198 pancakes can the restaurant make in two hours.

Which ordered pair is a solution to the linear inequality given below?
3x + 4y > 20
(-5,1)
(0,-3)
(-4,2)
(2,7)
Answer:
(2, 7 )
Step-by-step explanation:
Substitute the coordinates of each pair into the left side of the inequality and compare the result to the right side.
(- 5, 1 )
- 15 + 4 = - 11 < 20 ← not a solution
(0, - 3)
0 - 12 = - 12 < 20 ← not a solution
(- 4, 2 )
- 12 + 8 = - 4 < 20 ← not a solution
(2, 7 )
6 + 28 = 34 > 20 ← solution
The ordered pair which is correct for the given inequality will be equal to (2, 7). Hence, option D is correct.
What is inequality?Inequalities are mathematical expressions where neither side is equal. In inequality, as opposed to equations, we compare the two values. Less than (or less than and equal to), larger than (or greater or equal to), or not similar to signs are used in place of the equal sign in between.
As per the given information in the question,
The given inequality is,
3x + 4y > 20
For point (-5, 1)
3(-5) + 4(1) > 20
-11 > 20, this is incorrect.
For point (0, -3)
3(0) + 4(-3) > 20
-12 > 20, this is incorrect.
For points (-4, 2)
3(-4) + 4(2) > 20
-4 > 20, this is incorrect.
For points (2, 7)
3(2) + 4(7) > 20

He range R and the maximum height H of a projectile fired at an inclination θ to the horizontal with initial speed v0 are given by the formulas below, where g≈32.2 feet per second per second is the acceleration due to gravity. Complete parts A and B. R= 2v20sinθcosθ g H= v20sin2θ 2g
Answer:
A. R=1098.7ftB. H=274.7ftStep-by-step explanation:
"The question is not complete, here is the complete question
The range R and the maximum height H of a projectile fired at an inclination θ to the horizontal with initial speed v0 are given by the formulas below, where g≈32.2 feet per second per second is the acceleration due to gravity. Complete parts A and B.
[tex]R=\frac{2v_o^2sin \theta cos \theta}{g}[/tex]
[tex]H=\frac{v_o^2sin^2 \theta}{2g}[/tex]
A. Find the range R if the projectile is fired at an angle 45° to the horizontal with an initial speed of 190 ft per second
B. Find the maximum height H if the projectile is fired at angle 45° to the horizontal with an initial speed of 190 ft per second"
Solution
A. given the expression for Range R
substitute v= 190 ft/sec and ∅=45°
[tex]R=\frac{2(190)^2sin(45) cos(45)}{32.2}\\\\R=\frac{72200*0.7*0.7}{32.2}\\\\R=\frac{35378}{32.2} \\\\R=1098.7ft[/tex]
B. . given the expression for maximum height
substitute v= 190 ft/sec and ∅=45°
[tex]H=\frac{v_o^2sin^2 \theta}{2g}\\\\H=\frac{190*190*0.7*0.7}{2*32.2}\\\\H=\frac{17689}{64.4}\\\\H=274.7ft[/tex]
