Simplify the expression!
3/4(z+2/5)+2z =?
thank you for your help btw!!
The solution of the expression is (55z + 6 ) / 20.
What is an expression?Expression in maths is defined as the relation of numbers variables and functions by using mathematical signs like addition, subtraction, multiplication and division.
Given that the expression is 3/4(z+2/5)+2z. The expression will be solved as below,
E = 3/4(z+2/5)+2z
E = 3/4( z + 2 / 5 ) + 2z
E = 3/4 ( 5z + 2) / 5 + 2z
E = ( 15z + 6 + 40z ) /20
E = (55z + 6 ) / 20
Therefore, the solution of the expression is (55z + 6 ) / 20.

x1 = -2 - s
x2 = 7 - s
x3 = s
x1 -2 -1
x2 = 7 +s -1
x3 0 1
General solution of Ax = 0 will be

A softball pitcher has a 0.487 probability of throwing a strike for each pitch. If the softball pitcher throws 29 pitches, what is the probability that no more than 14 of them are strikes? Insert the correct symbol to represent this probability.
Answer:
P(x≤14) = 0.556
Step-by-step explanation:
Given:
Probability of throwing a strike (p) = 0.487
Total number of throw (n) = 29
Find:
Probability that no more than 14 of them are strikes P(x≤14)
Computation:
Mean(np) = (29)(0.487)
Mean(np) = 14.123
Standard deviation = √[mean( 1- p)]
Standard deviation = √[14.123( 1 - 0.487)]
Standard deviation = 2.6917 (Approx)
P(X < x) = P[(Z < (x - mean)]/[Standard deviation])
P(x≤14) = P(Z < (14.5 - 14.123) / 2.6917 )
P(x≤14) = 0.556
Darius filled up his gas tank with 24 gallons of gas. For each mile that he drives, he uses 0.06 gallons of gas. How may gallons of gas are left in the tank after driving 240 miles?
Answer:
9.6 gallonsStep-by-step explanation:
Step one:
Given that the capacity of the gas tank is 24 gallons.
we know that 1 mile will consume 0.06 gallons
therefore x miles will consume 0.06x gallons.
the consumption for any distance is given as
0.06x gallons.
Step two:
if x=240 miles
then the gallons consume will be
0.06(240)=14.4 gallons
Step three:
the remaining gallons of gas in the tank will be
24-14.4=9.6 gallons
The reamining gallons will be 9.6 gallons
The measure of an angle in standard position is given. Find two positive angles and two negative angles that are coterminal with the given angle. (Enter your answers as a comma-separated list.)
Answer:
The answer is below
Step-by-step explanation:
Let us assume the angle is -π/4.
Coterminal angles are angles that have the same initial side and terminal side. They are angles in standard position (angles with the initial side on the positive x -axis) that have a common terminal side.
Positive coterminal angles are gotten by adding 360° if the angle is in degrees or 2π for angles in radian while negative coterminal angles are gotten by subtracting 360° if the angle is in degrees or 2π for angles in radian.
Positive coterminal angle = -π/4 + 2π = 7π/4, 7π/4 + 2π = 15π/4
Positive coterminal angle = 7π/4, 15π/4
Negative coterminal angle = -π/4 - 2π = -9π/4, -9π/4 - 2π = -17π/4
Negative coterminal angle = -9π/4, -17π/4

Answer:
$15,475
Step-by-step explanation:
Mr. and Mrs. Jones make a combined $92,400 in taxable income. Looking at the table, their income is over $67,900 but not over $137,050.
So, the tax is $9,350. But, it also includes 25% of the amount over $67,900.
So,
$92,400 - $67,900 = $24,500
0.25 × $24,500 = $6,125
$9,350 + $6,125 = $15,475
