What is an equation?Equations are logical assertions in mathematics that have two algebraic expressions on either side of an equals (=) sign. The expression on the left and the expression on the right is shown to be equal in reference to one another. LHS = RHS (left hand side = right hand side) appears in all mathematical equations. You can solve equations to determine the value of an unknown variable that represents an unknown quantity.
The payroll of the baseball team is 2.48 × 10⁹ and,
The payroll of the football team is 2.8 × 10¹¹.
So, the football team's payroll is more than the baseball team's payroll by,
(2.8 × 10¹¹) - (2.48 × 10⁹)
= 2.7752 × 10¹¹.

At Elmo's, an old-fashioned barber shop in Melbourne, Florida, 66% of all customers get a haircut, 49% get a shave, and 40% get both.
a) What is the probability that a randomly selected person doesn't get a shave and doesn't get a haircut? Your answer should have at least 3 decimal places.
b) What is the probability that a randomly selected person gets a shave, given that they get a haircut? Your answer should have at least 3 decimal places.
The probability that a randomly selected person doesn't get a shave and doesn't get a haircut is 0.250.
The probability that a randomly selected person gets a shave, given that they get a haircut is 0.606.
What is the probability?The probability that a person selected at random would not get a shave or a haircut can be found as:
= 1 - (Prob. of haircut + Prob. of shave - Prob. of both)
= 1 - (0.66 + 0.49 - .40)
= 0.250
The probability that a random person would get a shave given they have gotten a haircut is:
= Probability of both / Probability of getting a haircut
= 0.40 / 0.66
= 0.606

Use the variable r to represent Rhonda's height.
Answer: 12+r=54
Step-by-step explanation:

Answer:
12+ r = 54
Step-by-step explanation:
If 54 is the sum, we put it at the end of the equations. Sum means 'the answer to an addition equation' so it must be add ( + )
If we use r to represent Rhonda's height then we have the equation of:

A quadrilateral is shown. One pair of opposite sides have lengths of 10 inches and (x + 2) inches. The other pair of opposite sides have lengths (x + 5) inches and (2 x minus 3) inches. Based on the measures shown, could the figure be a parallelogram? Yes, one pair of opposite sides could measure 10 in., and the other pair could measure 13 in. Yes, one pair of opposite sides could measure 10 in., and the other pair could measure 8 in. No, there are three different values for x when each expression is set equal to 10. No, the value of x that makes one pair of sides congruent does not make the other pair of sides congruent
Yes, one pair of opposite sides could measure 10 in., and the other pair could measure 13 in.
=============================================================
Explanation:
Let's say the top and bottom sides are 10 inches and (x+2) inches.
If this was a parallelogram, then those opposite sides must be parallel and the same length. So x+2 = 10 which leads to x = 8 after subtracting 2 from both sides.
Now let's consider the other pair of opposite sides (x+5) and (2x-3), which would be the left and right sides. Set them equal to one another and solve for x.
x+5 = 2x-3
x-2x = -3-5
-x = -8
x = 8
We arrive at the same x value, which confirms we do have a parallelogram.
Use this x value to find the unknown sides
x+2 = 8+2 = 10
x+5 = 8+5 = 13
2x-3 = 2(8)-3 = 13
This parallelogram has sides of 10, 13, 10, 13
It might be helpful to think of a 10 by 13 rectangle. However, the parallelogram may or may not be a rectangle.

Suppose that $3000 is placed in an account that pays 9% interest compounded each year. Assume that no withdrawals are made from the account. Follow the instructions below. Do not do any rounding. (a) Find the amount in the account at the end of 1 year. (b) Find the amount in the account at the end of 2 years.
Answer: (a) 3270 (b) 6270
Step-by-step explanation:
Formula for compound interest: P (1 + r/100 ) ^n,
where P = principal, r = interest rate, n = number of years
------------------------------------------------------------------------------------------------------------
In question (a),
P = $3000
r = 9%
n = 1
3000 ( 1 + 9/100) ^1 = $3270

In question (b),
P = $3000
r = 9%
n = 2
3000 ( 1 + 9/100) ^2 = $6270
maths midpoint theorem
please help
Step-by-step explanation:
2.
to complete the description :
PQ || MN || BC
the midpoint theorem :
the line segment in a triangle connecting the midpoints of two sides of the triangle is said to be parallel to its third side and is also half of the length of the third side.
therefore,
MN connects the midpoints of AC and AB, and is therefore half of BC.
PQ connects the midpoints of AN and AM, and is therefore half of MN. and that is half of half of BC = one quarter of BC.
MN = 1/2 × BC
PQ = 1/2 × MN = 1/2 × 1/2 × BC = 1/4 × BC =
= 1/4 × 16 = 4 mm
3.
UV = 10 cm connects the midpoints of PT and PS, and is therefore 1/2 of TS.
in other words, TS = 2×UV = 2×10 = 20 cm.
now we go the other direction from Q :
TS connects to midpoints of QU and QR. therefore,
UR = 2×TS = 2×20 = 40 cm.
VR = UR - UV = 40 - 10 = 30 cm
The area of a trapezoid is 145cm2. The height is 10cm and the length of one of the parallel sides is 10cm. Find the length of the second parallel side. Express your answer as a simplified fraction or a decimal rounded to two places
Answer:
19 cm.
Step-by-step explanation:
Area = h(a + b)/2
where h = height, and a and b are parallel sides,
145 = 10(10 + b)/2
290 = 100 + 10b
10b = 190
b = 19 cm.

Put the following equation of a line into slope-intercept form, simplifying all fractions. 6x-5y=-5
Answer: y = 6/5 x + 1
The slope intercept form of a linear equation is:
y = mx + b
where m is the slope and b is the y-intercept value.
According to the question we need the solve this equation for y:
6x – 5y = -5
This can be written as:
-6x + 5y = 5
-6x + 6x + 5y = +6x + 5
0 + 5y = 6x + 5
5y = 6x + 5
5y / 5 = (6x + 5) / 5

the mean weight of a group of 15 boys is 65 kg . one boy joins the group and his weight is 45 kg . what is the average weight of all the boys
I need the answer within 2 to 3 days!
Answer:
The new average is
63.75kg
Step-by-step explanation:
We have 15 boys with avg. weight of 65kg. That means that the sum of their weights is:
15*65kg = 975kg
We add a boy weighing 45kg. The new sum is
975kg + 45kg = 1020kg
To get the new average, we need to divide by the number of boys. It's no longer 15, because we've added one. It's now 16
avg_weight = 1020kg / 16 = 63.75kg
it takes 50 people 256 days to build a road how long will it take 80 people
The answer is that 80 people will build the same road in 160 days.
Given that 50 people take 256 days to build a road.
And we need to find out how many days will 80 people take to build the same road.
Disclaimer: Assuming that the work done by all the people are same.
If the number of people increases, the time taken to build the road decreases in the same proportion. Clearly, the number of people varies inversely to the number of days.
Let x denote the number of days required to build the road for 80 people.
Then the ratio, 80/50 = 256/x
⇒ x = (256×50)/80 = 160
Therefore, 80 people will build the same road in 160 days.

Given that Mary is going for a 3.5 km walk. So far she’s walked 1.55 km through the park, 0.6 km across the bridge, and 0.35 km up the hill and asked to find the fraction of the walk she has left
Total journey distance = 3.5 kilometers
Distance walked by mary on the bridge=0.6 kilometers
Distance walked by mary through the park=1.55 kilometers
Distance walked by mary up the hill=0.35 kilometers
Total distance traveled by mary=(0.6+1.55+0.35)kilometers
Total distance traveled by mary=2.5 kilometers
The distance left=3.5 kilometers-2.5 kilometers
The distance left=1 kilometer
1 kilometer is [tex]\frac{2}{7}[/tex] of the journey by assuming 3.5 kilometer will complete the jouney
