Answer:

We have been given that

72 persons has enough food for 7days.

After 1 day they decided to finish the food in remaining 3 days.

We need to find number of invitees to finish the food.

After one day there are 72 people and they have food for 6 days.

If people are changed n times, time will change to (1/n) of initial time.

\frac{1}{n}\times 6\ =\ 3n1×6 = 3

Therefore n = 2

Total number of people needed  = n × 72

Total number of people needed = 72×2

Total number of people needed  = 144

Hence the number of invitees = 144 - 72 =72

72 people are invited to finish the food in 3 days

Answer:

C

Step-by-step explanation:

Given

5| x - 7 | + 4 = 4 ( subtract 4 from both sides )

5 | x - 7 | = 0 ( divide both sides by 5 )

| x - 7 | = 0, thus

x - 7 = 0 ( add 7 to both sides )

x = 7 ← is the only solution → C

Answer:

4 4/10

Step-by-step explanation:

Well, 32/10 would by 3 2/10 when you divide it, I think. So 4 4/10 is greater.

Fractions may be equal or unequal.

[tex]\mathbf{4\frac{4}{10}}[/tex] is greater than [tex]\mathbf{\frac{32}{10}}[/tex]

The fractions are given as:

[tex]\mathbf{F_1 = 4\frac{4}{10}}[/tex]

[tex]\mathbf{F_2 = \frac{32}{10}}[/tex]

Express the fractions as improper fractions

[tex]\mathbf{F_1 = \frac{44}{10}}[/tex]

Both fractions have the same denominator.

So, the fraction with a greater numerator is greater.

By comparison: 44 is greater than 32

i.e. 44 > 32

Hence, [tex]\mathbf{4\frac{4}{10}}[/tex] is greater than [tex]\mathbf{\frac{32}{10}}[/tex]

24*2=48

48+8=56

56+2=58

58+2=60

lol other person did the multiplication so i did the long way

The arithmetic operation is used to make 60 by the number 2,4,6,8 with operation 6×4×2+8+4=60.

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

Multiplication, Subtraction, Summation, and division.

As per the given numbers,2,4,6,8

Let's multiply 6 and 4

6 × 4 = 24

Now let's multiply 24 by 2

24 × 2 = 48

So, 6 × 4 × 2 = 48

Now we need to add only 12 to get 60 so, 8 + 4 = 12

So, 6 × 4 × 2 + 8 + 4 = 60

Hence "The arithmetic operation is used to make 60 by the number 2,4,6,8 with operation 6×4×2+8+4=60".

Answer:

Step-by-step explanation:

we can find the equations for both lines and analyze after

[tex]y = mx + b\\where\\m = \frac{y_2-y_1}{x_2-x_1}\\\\[/tex]

AB:

[tex](12, 3), (-3, 9)\\m = \frac{9-3}{-3-12} = \frac{6}{-15} = \frac{-2}{5}[/tex]

[tex]y = \frac{-2}{5}(x) + b\\3= \frac{-2(12)}{5} + b\\3 = \frac{-24}{5} + b\\b = \frac{39}{5} \\y = \frac{-2}{5}(x) + \frac{39}{5}[/tex]

CD:

[tex](-6, 4) (-2, -6)\\m = \frac{4-(-6)}{-6-(-2)} = \frac{10}{-4} = \frac{-5}{2} \\y = \frac{-5}{2}(x) + b\\4 = \frac{-5(-6)}{2} + b\\4 = 15 + b\\b = -11\\y = \frac{-5}{2}(x) - 11[/tex]

Determining whether two lines are parallel or perpendicular involves looking at their slopes. AB has a slope of -2/5, CD has a slope of -5/2. Since these are not equal (not parallel) and not negative reciprocals of each other (not perpendicular), the lines are neither perpendicular or parallel.

Step-by-step explanation:

Answer:

[tex]\csc(\theta)=\sqrt{2}[/tex]

Step-by-step explanation:

Please refer to the attachment below.

We have:

[tex]5\cos^2(\theta)+6\sin^2(\theta)=11/2[/tex]

Remember that cosine is the ratio of the adjacent side to the hypotenuse. Therefore:

[tex]\cos(\theta)=\frac{b}{c}[/tex]

And sine is the ratio of the opposite side to the hypotenuse. Therefore:

[tex]\sin(\theta)=\frac{a}{c}[/tex]

Substitute into our original equation:

[tex]5(\frac{b}{c})^2+6(\frac{a}{c})^2=11/2[/tex]

Square:

[tex]\frac{5b^2}{c^2}+\frac{6a^2}{c^2}=\frac{11}{2}[/tex]

Multiply both sides by c squared:

[tex]5b^2+6a^2=\frac{11}{2}c^2[/tex]

Let’s also multiply both sides by 2 to eliminate the fraction:

[tex]10b^2+12a^2=11c^2[/tex]

Remember that according to the Pythagorean Theorem:

[tex]c^2=a^2+b^2[/tex]

Hence, we can make another substitution:

[tex]10b^2+12a^2=11(a^2+b^2)[/tex]

Distribute:

[tex]10b^2+12a^2=11a^2+11b^2[/tex]

Subtract 10b² from both sides:

[tex]12a^2=11a^2+b^2[/tex]

Subtract 11a² from both sides:

[tex]a^2=b^2[/tex]

Take the square root of both sides:

[tex]a=b[/tex]

Hence, a is equivalent to b.

Then, we must have a 45-45-90 Triangle.

Therefore, our angle θ is 45°.

We can substitute this back into our original equation to make sure. Remember that cos(45)=sin(45)=√2/2:

[tex]\begin{aligned} 5\cos^2(45)+6\sin^2(45)&=11/2 \\ 5(\frac{\sqrt{2}}{2}})^2+6(\frac{\sqrt{2}}{2})^2&=11/2 \\ 5(2/4)+6(2/4)&=11/2 \\ 5(1/2)+6(1/2)&=11/2 \\ 5/2+6/2&=11/2 \\ 11/2&=11/2 \;\checkmark \end{aligned} \\[/tex]

Hence:

[tex]\begin{aligned} \sin(45)&=\frac{1}{\sqrt{2}} \\ \Rightarrow \csc(\theta)&=\sqrt{2} \end{aligned}[/tex]

Answer:

y equals 17

So the larger of the two numbers is 17.

Step-by-step explanation:

So, here is what is given.

x+y=31

2x=y+11

So if x+y=31, then 2x+2y will equal 62. Replace 2x with what's given.

y+11+2y=62

3y+11 -11 =62 -11

3y=51

y=17.

Alternatively

x+y=31, and 2x=y+11

x -x +y=31 -x

y=31-x

2x=31-x+11

2x +x=42-x+x

3x=42

x=14

2(14)=y+11

28 -11 =y+11 -11

Again, y equals 17.

So the larger of the two numbers is 17.

The Width of cuboid is 11cm and Height of cuboid is 17 cm

An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax²+ bx + c = 0, where x is the variable, a and b are the coefficients, and c is the constant term. First, there must be a term other than zero in the coefficient of x² (a≠ 0) for an equation to be a quadratic equation. The x² term is written first when constructing a quadratic equation in standard form, then the x term, and finally the constant term. The numerical values of a, b, and c are often expressed as integral values rather than fractions or decimals.

Given:

Volume of Cuboid= 374

length= 2cm

width= x+ 3

height= x+ 9

Now, Volume of cuboid= length x width x height

2(x+3)(x+9)=374

2(x² + 12x +27)= 374

x² + 12x +27 = 187

x² + 12x -160=0

Now, factorizing

x² + 20x -8x-160=0

x( x+20) -8(x+ 20)=0

(x+ 20)(x -  8)=0

x= 8 and x= - 20

As. the dimensions cannot be negative.

So, Width= x+3 = 8+3 = 11cm

Height= x+9 = 3+9 = 17 cm

Answer:

The man traveled 12.70 miles.

Step-by-step explanation:

We can find the distance traveled by the man knowing:

[tex]d_{W}[/tex]: the distance at the west = 8.5 miles

[tex]\theta_{NW}[/tex]: the northwest angle = 42°

Then by using the following trigonometric identity we have:

[tex] sin(\theta) = \frac{d_{W}}{d_{NW}} [/tex]

[tex] d_{NW} = \frac{d_{W}}{sin(\theta)} = \frac{8.5 miles}{sin(42)} = 12.70 miles [/tex]

Therefore, the man traveled 12.70 miles.

  area = x(3x +10)

Step-by-step explanation:

The lengths of the unmarked sides are found as the difference between the lengths of the parallel marked sides.

  horizontal unmarked = (2x+15) -x = x +15

  vertical unmarked = (2x -5) -(x -5) = x

The area of the figure is the sum of the areas of parts of the figure. The area can be divided several ways. One is shown in the attachment, along with the areas of the parts and of the whole.

The whole area is ...

  x(2x -5) +x(x +15) = x((2x -5) +(x +15)) = x(2x -5 +x +15) = x(3x +10)
