Answer:
Step-by-step explanation:
1. ok so you need to use Pythagoras which is a^2 + b^2 = c^2
substituting 16 and 12 into 'a' and 'b' you get 16^2 + 12^2 = c^2
256 + 144 = c^2
400 = c^2 (square root each side to get ride of the square)
c = 20cm
2. doing the same thing you get c = 22.36 in
3. again doing it you get c = 15Ft
Hope this helps!
3. Samantha is training to run a marathon. The first week she runs 4 km each day. The next week, she runs 7 km each day. During each successive week (each week following), each day she runs 3 km farther than she ran the days of the previous week. If she runs for five days each week, what total distance will Sara run in a 12-week training session?
Answers
Week 1 = 5 x 4km = 20
Week 2 = 5 x 7km = 35
Week 3 = 5 x 10km = 50
Week 4 = 5 x 13km = 65
Week 5 = 5 x 16km = 80
Week 6 = 5 x 19km = 95
Week 7 = 5 x 22km = 110
Week 8 = 5 x 25km = 125
Week 9 = 5 x 28km = 140
Week 10 = 5 x 31km = 155
Week 11 = 5 x 34km = 170
Week 12 = 5 x 37km = 185
= 1230km
The total distance will Sara run in a 12-week training session is 1230 .
What is sum of terms in AP?An arithmetic progression is a sequence of numbers or variables in which the difference between consecutive terms is the same. There can be an infinite number of terms in an AP.
The formula for finding the sum of first n terms of an AP given in the form of "a, a + d, a+2d, a+3d, ....., a+(n-1)d" is:
[tex]S _{n}[/tex]= [tex]\frac{n}{2}[/tex] [tex][2a + (n-1)d][/tex]
According to the question
Samantha is training to run a marathon.
She runs for five days each week
The first week she runs 4 km each day. = 5 × 4 = 20
The second week, she runs 7 km each day. = 5 × 7 = 35
During each successive week , each day she runs 3 km farther than she ran the days of the previous week.
The third week, she runs 10 km each day. = 5 ×10 = 50
So on
Sara run in a 12-week training session
As this sequence is in AP
First term (a) = 20
common difference (d) = 35 - 20
= 15
Now,
Sum of 12 terms in AP
[tex]S _{n}[/tex]= [tex]\frac{n}{2}[/tex] × [2a + (n-1)d]
Substituting the values, a = 20, d = 15 and n = 12 in the above formula
[tex]S _{12}[/tex] = [tex]\frac{12}{2}[/tex] × [tex][2(20) + (12-1)15][/tex]
[tex]S _{12}[/tex] = [tex]6 [40 + (11)15}[/tex]
[tex]S _{12}[/tex] = [tex]6 [205][/tex]
[tex]S _{12}[/tex] = [tex]1,230[/tex]
Hence, the total distance will Sara run in a 12-week training session is 1230 .

Shane is mountain climbing with Naomi and had just climbed a 7.8 meter vertical rock face. Naomi is standing 6.2 meters away from the bottom of the cliff, looking up at Shane. How far away are Shane and Naomi? If necessary, round to the nearest tenth
Answers
Answer:
1.6 meters
Step-by-step explanation:
The distance between Shane and the bottom of the cliff is 7.8 meter while Naomi is standing 6.2 meters away from the bottom of the cliff.
As such, the distance between Shane and Naomi would be the difference between Shane's distance from the bottom of the cliff and Naomi's distance from the bottom of the cliff
= 7.8 - 6.2
= 1.6 meters
This is already in the nearest tenth

What role does substitution play when determining whether or not a given value is a solution to an equation or an inequality?
Answers
Answer:
Help verify values
Step-by-step explanation:
I basically help prove that the value fits and verifies that equation or inequality. By substituting a value for the variable within the equation or inequality and then solving it as a regular expression it should correctly output the same value on the other side of the equation or make the inequality true. For example, using the following inequality...
3x + 2 > 4
We can substitute the variable x for 2 and solve the inequality, if the inequality is true then we know that the value 2 is a correct and verified value.
(3*2) + 2 > 4
6 + 2 > 4
8 > 4 ... True

Brand B:
height of cone = 18 in.
radius of cone base=5 in.
A. Brand A
B. Brand B
C. Either - the hats have equal volumes
Answers
Brand A: π6^2(15/3)
Brand A: volume is about 565.49
Brand B: π5^2(18/3)
Brand B: volume is about 471.24
Brand A holds more volume so A would be the correct answer to the question.
Brand A hat is more preferable with largest volume i.e. 565.2 cu. inches.
What is Cone?A cone is a distinctive three-dimensional geometric figure that has a flat surface and a curved surface, pointed towards the top.
Here, Given data are:
Height of cone for Brand A = 15 in.
Radius of cone of Brand A =6 in.
Volume of Cone of brand A = [tex]\frac{1}{3}\pi r^2h[/tex]
V =[tex]\frac{1}{3}X 3.14X6^2X15[/tex]
V = 565.2 cu. in.
Height of cone for Brand B = 18 in.
Radius of cone of Brand B =5 in.
Volume of Cone of brand A = [tex]\frac{1}{3}\pi r^2h[/tex]
V =[tex]\frac{1}{3}X 3.14X5^2X18[/tex]
V = 471 cu. in.
Volume of brand A > volume of brand B.

I rectangular prism with a square base has a high of 7 inches the base of the prism can be completely covered with no overlap by 16 squares that each have a edge length of 1 inch what is the total surface area of the rectangular prism
Answers
Answer:
144 square inches
Step-by-step explanation:
Total surface area of the rectangular prism = Sum of all the area of its sides
Since it has a square base which can be covered by 16 squares of length 1 inch each, then;
length of its base = 4 inches
So that,
i. Area of its base = [tex]length^{2}[/tex]
= [tex]4^{2}[/tex]
area of its base = 16 square inches
ii. Area of one of the surfaces of its sides = length x width (or base x height)
= 4 x 7
= 28 square inches
Sum of the area of its vertical sides = 4 x 28
= 112 square inches
Thus,
Total surface area of the prism = 16 + 16 + 112
= 144 square inches
