Which expression is equivalent to 2 (a + 2 b) minus a minus 2 b? 3 a + 2 b 3 a minus 2 b a minus 2 b a + 2 b
Answer:
a + 2b
Step-by-step explanation:
Given the expression
2(a+2b) - a-2b
Open the bracket
2a+(2)2b- a-2b
2a+4b - a-2b
Collect the like terms
2a-a+4b-2b
a + 2b
Hence the equivalent expression is a + 2b

John drove his car due east for 8 miles. He then turned south and drove 15 miles. How far was he from where he started?
Answer:
John was 17 miles away from where he started.
Step-by-step explanation:
The easiest approach to this problem is to draw it out (check the attached image). Going East and turning South is the same as drawing a line towards the right, and then down on the paper.
Using the Pythagorean Theorem, we know that the sum of the square of the legs (2 smallest sides of a right triangle) is equal to the square of the hypotenuse of that triangle. In other words, [tex]a^2 + b^2 = c^2[/tex].
So to solve this, work backwards:
[tex]8^{2}+15^{2} =c^{2}\\64 + 225 = c^{2}\\289 = c^{2}\\c = \sqrt{289}\\ c = 17[/tex]
The distance between the initial and final point will be 17 miles.
What is a Pythagoras theorem?The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
This can be expressed as
H² = P² + B²
John drove his car due east for 8 miles.
He then turned south and drove 15 miles.
Then the distance between the initial and final point will be
H² = 8² + 15²
H² = 64 + 225
H² = 289
H = 17 miles

After 32 years from now a boy will be 5 times as old as he was 8 years back.How old is the boy now?
Answer:
18 years
Step-by-step explanation:
Transforming the question in form of equation:
Let x be the current age.
x + 32 = 5(x-8)
x + 32 = 5x - 40
5x - x = 40 + 32
4x = 72
x = 18
Answer: look at this! He’s 18
Step-by-step explanation:
equation = x+32=5(x-8)
X+32=5x-40
5x-x=32+40
4x=72
X=72/4
=18
A 6-ft vertical post casts a 16-in shadow at the same time a nearby cell phone tower casts a 124-ft shadow. How tall is the cell phone tower?
Answer:
558.01 ft
Step-by-step explanation:
To obtain the height of cell tower :
Height of post / shadow of post = height of tower / shadow of tower
Shadow of post = 16 in = 1.333333 ft
6/ 1.3333 = height of tower / 124
6 * 124 = 1. 3333 * height of tower
744 = 1.3333 * height of tower
Height of tower = 744 / 1.3333
Height of tower = 558.01
Height of tower = 558.01 ft

A man discovered he had only $5 bills and $1 bills. The number of $1 bills was 4 more than 3 times the number of $5 bills. He had a total of $36. How many of each kind of bill did he have?
The man had 4 $5 bills and 16 $1 bills.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
Let x be the number of $5 bills and y be the number of $1 bills.
From the problem, we know that:
y = 3x + 4 (since the number of $1 bills was 4 more than 3 times the number of $5 bills)
The total amount of money the man had is $36, so we can write:
5x + 1y = 36
Substituting the first equation into the second equation, we get:
5x + 1(3x + 4) = 36
Simplifying and solving for x, we get:
5x + 3x + 4 = 36
8x = 32
x = 4
So the man had 4 $5 bills.
Using the first equation, we can find the number of $1 bills:
y = 3x + 4 = 3(4) + 4 = 16
Therefore,
The man had 4 $5 bills and 16 $1 bills.

6. Which trig function would you use to solve for h? *
sine
cosine
tangent
Answer:
tan
Step-by-step explanation:
you can use this equation
[tex]tan(18) = \frac{h}{100} [/tex]
to solve for h
Answer:
Tangent
Step-by-step explanation:
Tangent=opposite/adjacent
For the angle that's 18°, it's opposite side is h, and the side that is next to, or adjacent to it is 100. It's not the other side because that's hypotenuse.
When you plug those in, you'll have:
[tex]tan(18)=\frac{h}{100}[/tex]
Solve for h by multiplying both sides by 100 to get:
[tex]100*tan(18)=h[/tex]
Put [tex]tan(18)[/tex] into calculator to get .324919. When you do so, make sure you're in degrees, not radians.
Since we are multiplying that by 100, the final answer is 32.4919

Four friends go out to eat and their meal
costs $86.50. The sales tax is 6.75% and
they should tip the waiter 20%. How much
should each person pay to the nearest cent?
Answer:
$23.13
Step-by-step explanation:
in total they would need to pay $23.13
Answer:
$27.41
Step-by-step explanation:
Meal Cost = $86.50
Sales Tax= 6.75% of the Meal Cost
= 6.75% X 86.50
= 0.0675 X 86.50
=$5.84
They tipped the Waiter 20%
20% of 86.50
=0.2 X 86.50
=$17.30
Total Bill= Meal Cost + Sales Tax + Tip
= 86.50 +5.84 + 17.30
=$109.64
Since the friends are four, each one will be expected to pay:
$109.64/4
=$27.41

The length of Rectangle A is 20 inches and the width is 4 inches. The length of Rectangle B is
40 inches. Find the width of Rectangle B if the rectangles are similar.
Answer:
8 inches
Step-by-step explanation:
Let w be the width of rectangle B.
Since, both rectangles are similar.
Therefore, corresponding lengths and widths of rectangles A and B will be in proportion.
[tex] \therefore \frac{20}{40} = \frac{4}{w} \\ \\ \frac{1}{2} = \frac{4}{w} \\ \\ w = 2 \times 4 \\ \\ w = 8 \: inches[/tex]
Answer:
8"
Step-by-step explanation:
Lᵃ/Wᵃ = Lᵇ/Wᵇ
20"/4" = 40"/Wᵇ
Wᵇ = (4"×40")/20"
Wᵇ = 160" ÷ 20"
Wᵇ = 8"
Width of rectangle B = 8 inches
