So in order to compare, the measurements have to same units. So lets convert everything to feet.
George 2 yds = 6 ft Kelsey 68 inches = 5 ft 8"
Mariah 5 feet Brian 5 ft 10 "
George measured the tallest at 6'
Hope this helped.
Answer:
7x+3
Step-by-step explanation:
To simpfly, it would help by simply ignoring the variable (x) and just looking at the number before it, solving it like a regular math problem, from left to right.
9(x) - 2(x) = 7(x)
(-4)-(-7) = 3 --> since there's a minus sign in the middle subtracting the two numbers and one on the -7, the -7 becomes a positive 7. A negative times a negative is always positive so, it would technically be -4+7=3.
Put both of these two numbers together and you get your answer,
7x+3.
If you're having trouble with the part I explained the image might help. Read it from left to right. A negative # + a negative # = positive #, as seen by the first row.
Answer:
- 81.04°F
Step-by-step explanation:
Given the question :
Convert - 62.8°C into F°
Using the conversion formula :
Fº = 1.8 x Cº + 32º
C = - 62.8°
Fº = (1.8 x - 62.8)+ 32º
F° = - 113.04° + 32°
= - 81.04°F

Answer: The flagpole is <u>
16 feet tall</u></h3>
==========================================================
Explanation:
The small markings for the angles in the diagram help us see how the angles pair up and how those pairs are congruent.
The square angle markers indicate we have 90 degree angles (aka right angles). That's one pair of congruent angles.
The other pair are the angles marked with small curves. We don't need to worry about the angle measure of these. All we care about is we have a second congruent pair of angles.
Having 2 sets of congruent angles allows us to use the AA (angle angle) similarity theorem.
The similar triangles allow us to set up the proportion below and isolate x.
-------------------
Let's solve for x.
6/x = 4.5/12
6*12 = x*4.5
72 = 4.5x
4.5x = 72
x = 72/(4.5)
x = 16
The flagpole is 16 feet tall.
This is somewhere between a 1 and 2 story building in terms of height.
Answer:
2/3*22/7*r^3=231.6
2/3*22/7=2.0952
2.0952*r^3=231.6
r^3=231.6/2.0952
r^3=
Step-by-step explanation:
2/3*22/7*r^3=231.6
