A ship takes 18 days to reach its designated part. It starts with food for its crew
of 450 men at the rate of 720gm per day per head. After 11 days of its journey they
rescued 180 passangers from a sinking ship. While rescuing the captain noticed a technical
problem in the ship's engine, and estimated the ship would reach the destination after 9
days. How much food should they now consume per day per head so that it lasts for the
rest of the journey.

The area of triangle ABC ABC is 18 cm2. Side AC=4x AC = 4 x and side AB=x+3 AB = x + 3 . Given that angle A=30∘ , calculate the value of x
Answer:
x = 3
Step-by-step explanation:
Let the altitude from B to AC intersect at point D. Then BD is a height of the triangle with base AC
ΔABD is a 30-60-90 triangle since m∠A = 30
Therefore, AB = 2(BD) or BD = AB/2 = (x+3)/2
Area of the triangle = bh/2 = AC(BD)/2 = 4x(x + 3)/(2)(2)
= x(x + 3) = 18
[tex]x^{2} + 3x = 18[/tex]
[tex]x^{2} + 3x - 18 = 0[/tex]
(x + 6)(x - 3) = 0
x = -6 or x = 3
x cannot equal -6, so x = 3
In this exercise we have to use the knowledge of triangle to calculate the value of X, in this way we find that:
[tex]X=3[/tex]
In this way, we can write the treated area of the triangle as:
[tex]bh/2 = AC(BD)/2 = 4x(x + 3)/(2)(2)\\=x(x + 3) = 18\\x^2+3x=18\\x^2+3x-18=0\\(x+6)(x-3)=0\\x=-6 \ or \ x=3[/tex]

Answer: 132.7 square inches
Area of a circle formula: [tex]\pi r^{2}[/tex]
Because we know that a diameter is twice the size of the radius and the diameter is 13 inches, we can divide 13 by 2 to get 6.5
Plug in this value into the formula, to get [tex]\pi (6.5^{2})[/tex]. Simplify the equation to get [tex]\pi (42.25)[/tex]. Multiply to get 132.7.
Answer:
It's A
Step-by-step explanation:
To find area= pie*raduis*radius
To find raduis you'll divide diameter by two
so 13 divided by 2 is 6.5
6.5*6.5*3.14=132.7

Answer:
Option C: b is parallel which is; y = ½x - 1
Step-by-step explanation:
We know that if the slope of a line is m, then the slope of the line that is perpendicular to it would have be; -1/m.
In this question, m = ½
Thus, the slope of the line that is perpendicular to it is; -1/(½) = -2
However, to find the slope of the line parallel to it would mean that the value of m which is the original slope will remain the same. Original slope = ½, thus the only option with slope as ½ is option C where b is parallel with the equation; y = ½x - 1

Below. What is m∠1?
m∠1 =
Answer:
m∠1 = 70°
Step-by-step explanation:
Step 1
Sum of angles on a straight line = 180°
Hence:
180° - 101°
= 79°
Sum of interior angles in a triangle = 180°
Hence
m∠1 = 180° - (79 ° + 31°)
m∠1 = 70°

Suppose HIJK is a parallelogram. Find the value of x and y.
Answer:
x = 90, y = 12
Step-by-step explanation:
The key to this problem is the fact that opposite sides of a parallelogram are congruent (their lengths are equal).
Set up and solve two equations, one for x and one for y.
x + 80 = 2x - 10
80 = x - 10
90 = x
--------------------------
3y - 4 = y + 20
2y - 4 = 20
2y = 24
y = 12

A bakery owner wants to keep his bakery open a few more hours every evening. He wants to conduct a survey to determine whether extending the bakery's hours would be what costumers want. Which survey method would likely produce the most representative sample?
Answer:
Ask every tenth customer over the period of a week.
Step-by-step explanation:
Required
Select which of the options is true
(a) Every 5th male customer
This method will not produce a correct representative sample because only the male customers are surveyed. The opinion of the female customers will not be represented in the sample
(b) Every customer after 5:00pm
This method will not produce a correct representative sample because only the customers who come to the bakery before 5:00pm will not be represented. The opinion of these customers will not be represented in the sample
(c) Every 10th customer over the week
This method will produce a correct representative sample because the opinions of the customers are taken, irrespective of the gender or the time the customer walks into the bakery.
After a month of successful fundraising,
Elena and her classmates voted on
whether to donate the money they had
raised to hunger relief or to environmental
causes. 50% of the 12 votes were in favor
Of hunger relief. How many votes were
for hunger relief?
Answer:
6
Step-by-step explanation:
50% of 12= 1/2 of 12= 6
Answer:
6 votes were for hunger relief.
Step-by-step explanation:
Total number of votes = 12
Percentage of votes for hunger relief = 50%
So, number of votes for hunger relief would be:-
50% of 12 votes
That equals--> [tex]\frac{50}{100}[/tex] x 12
= 0.5 x 12
= 6 votes

The surface area of the three-dimensional figure is
square centimeters.
Picture is quite a bit more helpful
Answer:
Total surface area = 536.6 cm²
Step-by-step explanation:
Surface area of the given figure = Area of rectangle (1) + Area of rectangle (2) + Area of rectangle (3) + Area of triangle (4) + Area of triangle (5)
Area of rectangle (1) = Length × Width
= 10 × 15
= 150 cm²
Area of rectangle (2) = 10 × 15
= 150 cm²
Area of rectangle (3) = 10 × 15
= 150 cm²
Area of triangle (4) = [tex]\frac{1}{2}(\text{Base)}(\text{Height})[/tex]
= [tex]\frac{1}{2}(10)(8.66)[/tex]
= 43.3 cm²
Area of triangle (5) = [tex]\frac{1}{2}(10)(8.66)[/tex]
= 43.3 cm²
Total surface area = 150 + 150 + 150 + 43.3 + 43.3
= 536.6 cm²

What is a expression? What is a mathematical equation?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.We have the following inequality -
x < - 2
Given is -
x < - 2
Now, it can be seen that -
- 3 < - 2
Therefore, only x = -3 is less than -2.
