the sum of two numbers is 31. if one of these numbers is x and x is 11 more than the other number what is the value of x

Answers

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.

A man travels at 42 degrees northwest, and ends up 8.5 miles west of his starting point. How far did he travel?

Answers

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.

If 5cos^2θ + 6sin^2θ =11/2
, the value of cosecθ =--------

Answers

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]

What is Quadratic Equation?

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

Answers

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]

72 persons have enough food for 7 days . but after one day they decided to finish the food in 3 remaining days . For if they invited more persons how many persons did they invite?​

Answers

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

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

What is the arithmetic operator?

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:

y=1/2x+4

Step-by-step explanation:

Refer to the picture that given :)

The first thing you have to find is the y-intercept.

The y-intercept is when the line INTERCEPT the y-axis and as you can see point 4 is the one that is intercepting.

To find the slope you just have to use the slope intercept form
M= rise/run

rise(up+/down-) and run(right+/left-)

So you put your pencil in point for and go 2 times up(+) and then 6 times left(-) to each the other point.

You slope is -2/6 or you can simplify to -1/3 because you can divide by 2 (2:2=1 and 6:2=3)

The slope was negative because number 2 is positive and number 6 is negative (+) + (-) is negative.

The final equation is y= -1/3x+4

The formula that you use is this y=Mx+b

(M is the slope, x is just x and b is the y intercept)

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.
