Answer:
m = 21 inches
The model length is 21 inches
Question;
Use the scale factor 1:12 to find the missing dimension. Great white shark actually lengthy 21ft. Find the model length in inches.
Step-by-step explanation:
Given;
Scale factor = 1:12
Actual length a = 21 ft
Let m represent the model length;
The ratio of model length to actually length is given as;
m/a = 1/12
m = a/12
Substituting a=21 ft;
m = 21/12 ft
Converting to inches;
1 ft = 12 inches
So,
m = 21/12 ft × 12 inches/ft
m = 21 inches
The model length is 21 inches
Answer:
Step-by-step explanation:
What we know
total sum of angles = 540 deg
3/2 b cam also be written as 1.5b degrees.
So 1.5b + (b+45) + (2b - 90) +90 = 540
Step 1 -- get rid of parenthesis
1.5b + b + 45 +2b -90 +90 =540
Step 2 -- combine the like expressions
4.5b + 45 = 540
Step 3 -- subtract 45 from both the sides
4.5b = 495
Step 4 -- divide 4.5 from both the sides
b = 110 ----- not the right answer
Thats not right okay im sorry
but i guess if it is not 110 it should be 100, 90 etc.
90 = b is correct
<span>reflection over the x-axis and a translation 4 units down
Refelcting f(x) over the x axis gives
-f(x)=-3x-1
Subtracting a constant from -f(x) moves the graph of -f(x) that many units down.
-f(x)-4=-3x-5=g(x)
This shows that g(x) is obtained by reflecting f(x) over the x-axis and then translating 4 units down.</span>
Answer:
(A) and (D)
Step-by-step explanation:
It is given that Three basketball teams measured the height of each player on their team.
Team Mean height (cm) MAD (cm)
Bulldogs 165 6.9
Panthers 177 7.1
Warriors 176 4.8
From the information given, The heights of the Bulldogs’ players vary more than do the Warriors’ heights and The heights of the Panthers’ players and those of the Warriors vary about the same amount.
Therefore, option A and d are the correct statements about the data given.
31a) Think of $30.90 as 100% of her bill, we first want to find 6%
To work out how much this is, we need to divide the percentage by 100 to get a multiplier (decimal)
6/100 = 0.06
Multiply 0.06 and $30.90 to get the tax
$30.90 x 0.06 = 1.854
As we can't have part of a cent, we round to the nearest 100th
If the number to the right of this value is below 5 we round down, 5 or more we round up
4 is below 5 so we round down
$1.85
31b) For the total bill, we need to add together the original and the tax
$30.90 + $1.85 = $32.75
32a) Simple Interest = PRT
This means
P x R x T
We need to multiply together the Principal, Rate and Time span
We need to turn the percentage into a decimal, so we divide by 100 like before
3.2 / 100 = 0.032
$750 x 0.032 x 6 = $144
32b) To find the account balance, we need to add the interest to the original amount
$750 + $144 = $894
