Part B: Solve 2a − 5d = 30 for d. Show your work. (6 points)

Answers

Answer 1

Answer: Given Equation: 2a − 5d = 30

Solution:

2a - 5d = 30

-5d = 30 -2a

d = ( 30 - 2a )/ (-5)

= -6 + (2a/5)

= (2a/5) - 6

Answers

always makes you always go from the x to the y axis!! sorry if this didn’t help much

Answer:

Follow the lines

Step-by-step explanation:

Follow what the lines go with what the table has.

To make this really easy, find the slope of the line

To do this you find an easy point.

Ex. x=3 and y= 150

then take it into a slope y-intersept formula

y= mx

150= 3x

50 = x

so for every time x goes up one interval, y increases at a rate of 50.

And for y, do the opposite, for every 50 y, x goes up 1.

By following this linear path, you should really beable to solve the graph on the right. (If you need to, use a calculator for dividing the y numbers by 50 to get x)

y= 50x is ur slope/formula

(Ill leave the rest for you to answer with this data above ;) )

Answer:

Denote the two points are A and B, the balloon is C. Then we have,

Side AB = 9 miles

Angle CAB (angle A) = 27 deg

Ange CBA (angle B) = 45 deg

=> Angle ACB (angle C) = 180 - 27 - 45 = 108 deg

Applying the sine theorem:

AB/sinC = BC/sinA

=> BC = AB x sinA/sinC = 9 x sin27/sin108 = 4.3 miles

Denote CH as the height from C to side AB (or distance from ground to balloon), we have:

CH = BC x sin B = 4.3 x sin*45 = ~3.04 miles

=> Distance from ground to balloon: ~3.04 miles

Hope this helps!

Answer:

3.0 miles

Step-by-step explanation:

Let h be the height

Tan(27) = h/b

h = btan(27)

Tan(45) = h/(9-b)

(9-b)tan(45) = h

(9-b)tan(45) = btan(27)

9tan(45) = b[tan(45) + tan(27)]

b = 5.962138633

h = btan(27) = 3.037861367

We have: $\overline{abc}$

What number is 35% of 22

Answers

The number n = 7.7 is 35 percentage or 35 % of 22

What is Percentage?

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.

Percentage change is the difference between the measured value and the true value , as a percentage of the true value

Percentage change =( (| Measured Value - True Value |) / True Value ) x 100

Given data ,

Let the number be represented as n

Now , the value of n is calculated as

Let the percentage be = 35 %

Substituting the values in the equation , we get

( 35 % ) of 22 = n

On simplifying the equation , we get

( 35/100 ) x 22 = n

n = ( 770/100 )

On further simplification , we get

n = 7.7

Hence , the number is n = 7.7

how to draw an arrow diagram that relates a number (0to9) to the number of lit segments required to display that number?

Answers

The numbers on electronic displays ... like on alarm clocks or digital
watches ... are made out of what's called "7-segment" displays.

For each digit, there's a set of 7 tiny LED's that are laid out
something like this: _
/_/
/_/

Then, all of the digits from 0 to 9 can be made just by lighting up
some of the segments, and keeping the rest turned off.

This question is asking for a table that shows how many segments
are lit up to make each digit ... not which ones, but just how many.
This is something the design engineers want to know, so that they
can be sure to provide enough power inside the clock to light up
all the digits.

Look at the picture I attached. It shows all the digits, 0 to 9, the way
they look in 7-segment displays, and on the right side, the number of
segments that are lit up to make each digit.

I think this is something like what the question is asking for.
