Answer:
[tex](a)\ k_2 = 1in:3ft[/tex]
[tex](b)\ Scale\ width =\frac{16}{3}\ in[/tex]
Step-by-step explanation:
Given
[tex]k_1 = 1in : 2ft[/tex] --- Initial scale factor
[tex]Blueprint: 12in\ by\ 8in[/tex] --- Missing from the question
Solving (a): The new scale factor.
Convert the initial blueprint to actual measurement using the initial scale factor, we have:
[tex]Length = 12 * 2ft = 24ft[/tex]
[tex]Width = 8 * 2ft = 16ft[/tex]
From the question, we understand the new scale factor represents the width as 8in.
The scale factor (k2) is then calculated as:
[tex]k_2 = \frac{Scale\ length}{Actual\ length}[/tex]
[tex]k_2 = \frac{8in}{24ft}[/tex]
Simplify
[tex]k_2 = \frac{1in}{3ft}[/tex]
Represent as fraction
[tex]k_2 = 1in:3ft[/tex]
The above is the new scale factor
Solving (b): The new width
Using the scale factor above we have:
[tex]k_2 = \frac{Scale\ width}{Actual\ width}[/tex]
[tex]\frac{1in}{3ft} = \frac{Scale\ width}{16ft}[/tex]
The 16 is gotten from:
[tex]Width = 8 * 2ft = 16ft[/tex]
So, we have:
[tex]Scale\ width = 16ft * \frac{1in}{3ft}[/tex]
[tex]Scale\ width = 16 * \frac{1in}{3}[/tex]
[tex]Scale\ width =\frac{16\ in}{3}[/tex]
[tex]Scale\ width =\frac{16}{3}\ in[/tex]
Hence, the scale width of the blueprint is: 16/3 inches
Answer: Part A is 3 and part b is 5 1/3 inches

Meteor Crater, located near Flagstaff, Arizona, is a circular
crater with a circumference of 2.32 miles. What is the
approximate diameter of the crater?
Answer:
The approximate diameter of the crater is 0.74 mile.
Step-by-step explanation:
Circumference of a circle(C)=2*π*r(radius of the circle)
2.32 miles=2π*r
or, r=2.32 miles/2π
So, r=0.369 mile
Then,
d=2r
d=2*0.369 mile
So, d= 0.74 mile

13.At the Finch School bake sale, donuts sell
for $2 each muffins sell for $3 each. A
combined total of 104 donuts and muffins
are sold, resulting in $243 in sales. Which
of the following statements must be true?
a. 69 more muffins were sold than donuts.
b. 34 more muffins were sold than donuts.
c. 34 more donuts were sold than muffins.
d. 69 more donuts were sold than muffins.
Answer:
c)
Step-by-step explanation:
create a system of equations:
d + m = 104
2d + 3m = 243
now use substitution method based on 'd = 104 - m'
2(104 - m) + 3m = 243
208 - 2m + 3m = 243
208 + m = 243
m = 35
So, 35 muffins and 69 donuts were sold.
This is 34 more donuts than muffins.

Well hello there! My name is Lunako, and I'm here to help you out.
What we need to do:Firstly, do you remember the formula for finding the volume of the sphere? Yep, it's 4π(r³/3)! I'll substitute r for 5.6 -- which is 11.2 divided by 2, but you knew that already right? -- and π for 3.14 -- I'm doing that for relative ease.
4(3.14) * (5.6³/3) {Firstly we need to need find the cube of 5.6. That would be 175.616. Let me show the work for that: 5.6 * 5.6 = 25 + 3 + 3 + 0.36 = 31.36; 31.36 * 5.6 = 150 + 5 + 1.5 + 0.3 + 18 + 0.6 + 0.18 + 0.036 = 155 + 1.8 + 18.6 + 0.216 = 156.8 + 18.816 = 175.616}
4(3.14) * (175.616/3) {Now divide 175.616 by 3 to get 58.5387 (rounded to 54 places).}
4(3.14) * 58.5387 {Now onto the left sides. 3.14 quadrupled is 12.56.}
12.56 * 58.5387 {Now for the last step: Multiplying 12.56 by 58.5387. The work for that is shown in the picture. You should get 735.246072.}
735.246072 in³ {While this is the answer, we need to round it to two decimal places, like in the answer choices. 6 is greater then 5, so round up to 735.25.}
735.25 in³ {And with that this problem is solved.}
The Answer:The volume of the sphere is 735.25 cubic inches, which is D.

If I went to the store in a boat on a boat how cold was it true or false.
Answer:
Any temp less than 70 degrees is dangerous. So really, probably the worst thing about cold weather boating is the danger if you fall in. If it's really cold and you are bundled up, you don't have as much flexibility. If you have gloves on, you can't get the same grip.

a line that passes through (4,5) and (0, -12)
Answer:
Step-by-step explanation:
Hello : let A(4,5) B(0,-12)
the slope is : (YB - YA)/(XB -XA)
(-12-5)/(0-4) = 17/4
an equation is : y=ax+b a is a slope
y = (17/4)x +b
the line through point B(0,-12) : -12 = (17/4)(0)+b
b =-12
the equation is : y =(17/4)x-12

Nya wants to buy a sweater that had an original price of $50. The sweater is now discounted 15% and the sales tax rate is 6%. How much will Nya pay for the sweater? Round to the nearest cent (hundredths place). *
Answer:
$45.05
Step-by-step explanation:
Sale price of sweater is (1.00 - 0.15)($50), or 0.85($50) = $42.50. Nya has to pay 6% sales tax on this $42.50. Thus, the final amount due is
(1.00 + 0.06)($2.50) = $45.05
Answer:
46.42
Step-by-step explanation:
First step is to find the discount
Discount = original price * discount rate
= 55 * 20%
= 55*.20
=11
Take the discount from the original price and that is the new price
new price = original price - discount
= 55-11
=44
Now we need to find the tax
tax = new price * tax rate
= 44 * 5.5%
= 44 * .055
=2.42
The final price is the new price plus the tax
final price = new price + tax
= 44+2.42
=46.42
Therefore, Nya will pay $46.42 for the sweater if she buys it.
