Answers
Answer:
D (6)
Step-by-step explanation:
FIRST METHOD
1. Use vector analogy (If you learnt)
Consider WS as a vector
x component of WS is 5
y component of WS is 3
2. Plug in numbers (Pythagorean Theorem)
[tex]\sqrt{5^{2}+3^{2}}[/tex] ≈ 5.83
Nearest integer is 6
SECOND METHOD
1. Distance between two points formula
[tex]d (length) = \sqrt{(x_{1}-x_{2})^{2}+(y_{1}-y_{2})^{2}}[/tex]
W = (x1,y1) S = (x2,y2)
W = (-2,-1) S = (3,2)
2. Plug in numbers
[tex]d (length) = \sqrt{(-2-3)^{2}+(-1-2)^{2}}[/tex]
3. d ≈ 5.83

Rebecca saved AED 175.30 in June and AED 132.50 in July. Then she bought a bicycle for AED 195.80. How much of her savings from June and July was left?
Answers
Answer:
her saving that was left from June and July is 112
Step-by-step explanation:
The computation of the saving amount left is shown below;
= Total saving in 2 months - amount spent
= 175.30 + 132.50 - 195.80
= 112
Hence, her saving that was left from June and July is 112

has a height of 11 in and a radius of 6 in.
What is the approximate volume of the whole shape? Round your answer to the nearest tenth. Use
3.14 to approximate pi. (Show your work.)
Answers
Answer:
Answer: 284.7
Step-by-step explanation:
Step-by-step explanation:
radius of cone and hemisphere are the same
volume of half sphere=(1/2)*(4/3)*
=(1/2)*(4/3)*3.14* (4*4*4=64)
=133.97333
=133.97
volume of cone= (1/3)h
=(1/3)*3.14**9 (4*4=16)
=150.72
total volume=133.97+150.72
=284.69
=284.7

A farmer wants to build two fenced-off sections within his field, one in the shape of a rectangle and the other in the shape of a square. The side of the square must be equal to the width of the rectangle, x feet. The length of the rectangle must be 50 feet longer than its width. The field the farmer wants to build the two fenced sections in has an area of y square feet. The difference of the area of this field and the area of the fenced, square section needs to be at least 1,000 square feet. In addition, the sum of the fenced areas must be less than the area of the field. This is the system of inequalities that represents this situation. Which points represent viable solutions?

Answers
Answer:
M = 1 & 13M²-14m+13 = 0
m²-13m-m+13 = 0
m(m-13)-1(m-13) = 0
(m-1)(m-13) = 0
m = 1 & 13
Step-by-step explanation:
M²-14m+13=0

=> m(m-13)-1(m-13) = 0
=> (m-1)(m-13)=0
=> m= 1 and 13

Answers
Answer:
I don't know sorry
Step-by-step explanation:

The function N(x) that represents the number of ounces of peanuts in the mixture is N(x)=x.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
Given that, Amir has 48 ounces of cashews, walnuts, and pecans.
He adds x ounces of peanuts to create a mixture.
M(x) that represents the number of ounces of all nuts in the mixture.
M(x)=48
N(x) that represents the number of ounces of peanuts in the mixture.
So, N(x)=x
Now, (M/N)(x) = M(x)/N(x)
= 48/x
Therefore, the function N(x) that represents the number of ounces of peanuts in the mixture is N(x)=x.
