If two pounds of meat will serve 5 people, how many pounds will be needed to serve 13
people?
Answer:
Step-by-step explanation:
2 pounds / 5 people
x pounds / 13 people
2/5 pounds per person so 2/5 * 13 = 26/5
5 1/5 i think
sorry if its wrong
Answer: The answer of the question is 2 and 3/5.
Step-by-step explanation: Every pound of meat serves one person, because 10 divided by 2 people is 5. Then, there are 3 pieces of meat left over, and since every person eats 5/5, or 1 whole, then there are 3/5 pieces left over. You then add 2 and 3/5 together, getting your answer 2 3/5.

if <1 and <2 form a linear pair and m<1 is 18 degrees less than five times the measure of <2 find m<1
∠1 and ∠2 will have the values 33° and 147° respectively when they form a Linear Pair.
In the question, It is given that ∠1 and ∠2 form a Linear Pair.
So, ∠1 and ∠2 = 180°, Also it is stated that ∠1 is 18° lesser than 5 times ∠2.
Taking ∠2 = x we get ∠1 = 5x-18
Now for Linear Pair, we have ∠1 + ∠2 = 180°
putting values of ∠1 and ∠2 we get : (5x-18) + x = 180
Solving the equation => (5x-18) + x = 180 => 6x = 198
=> x = 33
Putting the value of x in both ∠1 and ∠2 we get :
∠2 = 33° and ∠1 = 5(33) - 18 => ∠1 = 147°
Hence, we get ∠1 and ∠2 measures 147° and 33° respectively.

richard cuts a $ 4\frac{1}{2} ~\text{ft} \times 7\frac{1}{2} ~\text{ft} \times 11\frac{1}{4}~ \text{ft}$ rectangular prism into congruent cubes without any part of the prism leftover. if he makes the cubes as large as possible, how many will he produce?
If he makes the cubes as large as possible, the maximum number of cubes is equal to 900 cubes.
How to determine the number of cubes?In order to determine the number of cubes that would be produced by Richard when the rectangular prism is cut into congruent cubes without any part of the rectangular prism leftover, we would make the edges of the cube 100 times larger and then evaluate:
Length of cube = 4 1/2 ft × 100 = 450 feet.Breadth of cube = 7 1/2 ft × 100 = 750 feet.Height of cube = 11 1/4 ft × 100 = 1125 feet.Note: The greatest common factor (GCF) of the dimensions above is 75.
Next, we would divide each of the dimension by 75:
Length of cube = = 450/75 = 6 feet.
Breadth of cube = 750/75 = 10 feet.
Height of cube = 1125/75 = 15 feet.
Therefore, the maximum number of cubes is given by:
Maximum number of cubes = 6 × 10 × 15
Maximum number of cubes = 900 cubes.

use vectors to prove that the line joining the midpoints of two sides of a triangle is parallel to the third side and half its length.
We have proved that the line joining the midpoints of two sides of a triangle is parallel to the third side and half its length by using a vector.
What do you mean by vector?A quantity or phenomenon with independent qualities for both magnitude and direction is called a vector. The term can also refer to a quantity's mathematical or geometrical representation. Velocity, momentum, force, electromagnetic fields, and weight are a few examples of vectors in nature. A quantity or phenomenon that just exhibits magnitude and no specific direction is referred to as a scalar. (Weight is the force produced by the acceleration of gravity acting on a mass.) Scalars include things like velocity, mass, electrical resistance, and hard disk storage space.
In the triangle ABC, D is the midpoint of AB, and E is the midpoint of AC.
Now, using the triangle rule for triangle ADE,
AE+AD = ED
And for triangle ABC,
CA+AB = CB
2AE+2AD = CB [as AD = 1/2AB and AE=1/2AC]
=> 2(AE+AD) = CB
=> 2ED = CB
=> ED = CB/2
We can write two vectors equal to each other with only difference in magnitude only when they are parallel, i.e., the angle between ED and CB is 0.

11. Put brackets into each of the following expressions to make it correct:
(a) 3+9/5-2x5=20
Answer:
(3+9)/(5-2)x5 = 20
Step-by-step explanation:
It's a rather tedious type of task, because there's no simple way to solve them, except kind of by brute force or by trial and error. Here we can start by noticing x5 at the end, so if we can force everything before to be 4 it's gonna be dandy:
can we add brackets to 3+9/5-2 to be equal to 4 (because 20 / 5)?
fortunately, 3+9 is 4 times more than 5-2, so (3+9)/(5-2) = 4
so (3+9)/(5-2)x5=20 is a correct solution
Salome's house went from a valuation of 4.5 million ZAR (South African Rand) on 1st January
2011, to 6 million ZAR on 1st January 2020.
If the value of the house compounded monthly, what was the annual rate of increase?
Give your answer as a percentage, correct to 1 decimal place.
Using compound interest, it is found that the annual rate of increase was of 3.10%.
What is compound interest?The amount of money earned, in compound interest, after t years, is given by:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
In which:
A(t) is the amount of money after t years. P is the principal(the initial sum of money). r is the interest rate(as a decimal value). n is the number of times that interest is compounded per year.For this problem, the parameters are given as follows:
t = 9, A(t) = 6, A(0) = 4.5, n = 12.
Hence we solve for r to find the interest rate as follows:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
[tex]6 = 4.5\left(1 + \frac{r}{12}\right)^{12 \times 9}[/tex]
[tex]1 + \frac{r}{12}\right)^{108} = 1.33[/tex]
[tex]\sqrt[108]{1 + \frac{r}{12}\right)^{108}} = \sqrt[108]{1.33}[/tex]
[tex]1 + \frac{r}{12} = (1.33)^{\frac{1}{108}}[/tex]
1 + r/12 = 1.0026.
r/12 = 0.0026
r = 12 x 0.0026
r = 0.031.
The annual rate of increase was of 3.10%.

A television transmitter tower is 600 ft high. If the angle between the guy wire (attached at the
top) and the tower is 55.4°, how long is the guy wire?
Using trigonometric relations, we can see that the length of the wire is 1,454.5 ft.
How can we find the length of the wire?
We can think of this as a right triangle, such that the height of the tower is one of the legs, and the wire is the hypotenuse.
In this case, we know that the angle between the tower and the wire measures 55.4°, and the height is the adjacent cathetus to this angle.
Then we can use the relation:
cos(a) = (adjacent cathetus)/(hypotenuse)
Where:
a = 55.4°
adjacent cathetus = 600ft
hypotenuse = L = length of the wire.
Replacing that we get:
cos(55.4°) = 600ft/L
L = 600ft/cos(55.4°) = 1,454.5 ft
We conclude that the length of the wire is 1,454.5 ft.

Solve system of equations.
x+y=-6
2 x-y=3
The system of equations involving x + y = -6 and 2x - y = 3 has the solution x = -1 and y = -5.
A system of linear equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy both equations.
There are three methods that can be used to solve system of linear equations.
1. Elimination
2. Substitution
3. Graphing
Using substitution method, given two linear equations in x and y,
x + y = -6 (equation 1)
2x - y = 3 (equation 2)
Express y in terms of x in one of the equations,
x + y = -6 (equation 1)
y = -x - 6
and then substitute it in the 2nd equation.
2x - y = 3 (equation 2)
2x - (-x - 6) = 3
2x + x + 6 = 3
3x = 3 - 6
3x = -3
x = -1
Substituting the value of x in the equation of y,
y = -x - 6
y = -(-1) - 6
y = 1 - 6
y = -5

Changes in portion sizes (which may entail adjusting the recipe's batch size) and improved use of the preparation tools available are two additional reasons to modify recipes (for example, you need to divide a recipe to make two half batches due to a lack of oven space).

We get that the absolute inequality will be | x + 16 | < 8.
We are given two inequalities:
x < - 8 and x > 24
We need to write one inequality by combining both the inequalities.
We know that:
x < - 8 means that x can have any value less than - 8
x ∈ ( - ∞ , - 8 )
Also, x > 24 means that:
x ∈ ( 24 , ∞ )
So, combining these, we get that:
