Can You Help Me Please

Answers

Answer 1

Answer:

Please check the explanation.

Step-by-step explanation:

Given that

|v|=38

Ф = 120°

Finding the horizontal component

The horizontal component can be obtained using the formula

Vx = |v| cos Ф

     = 38 cos 120°

     = 38 (-0.5)

      = -19

Thus, the  horizontal component is:

Vx = -19

Finding the vertical component

The vertical component can be obtained using the formula

Vy = |v| sin Ф

    = 38 sin 120°

    = 38 (0.86)

    = 32.68

Thus, the vertical component is:

Vy = -19

A vector 'v' with magnitude |v| and direction Ф can be written as:

v = |v| cos Ф i + |v| sin Ф j

As

|v|=38

Ф = 120°

Thus, the vector is

v = 38 cos 120° i + 38 sin 120° j

or

v = -19 i + 32.68 j

she made the socks?

Answers

Answer: 2 pair of sock/hour

Explanation:

She can make 6 pairs in 3 hour.

3 hour = 6 pair
=> 1 hour = 6/3
=> 1 hour = 2 pair

It takes 2.5 yards of material to make a dress. Harley's Clothing Design estimates that they can produce 48 dresses each week. If there are 52 weeks in a year, how much material will they need to purchase to make dresses for a year?

6,240 yards
150 yards
5,910 yards
2,704 yards

Answers

Answer:

The answer is 6,240 yards

Step-by-step explanation:

If there is 48 each week thats basically 48×52 = 2496 which is how many dresses times how many yards per dress(2.5)I get 6240.

Hope this helps!!

Answer:

6240

Step-by-step explanation:

Amount of material it takes to make 1 dress = 2.5 yards

Amount of dresses Harley's Clothing Design will produce each week = 48 dresses

Number of weeks in 1 year = 52

2.5*48= 120

120 yards of material used in 48 dresses in one week.

120*52=6240

Therefore, the store will need to purchase 6240 yards of material in order to produce 48 dresses per week for 52 weeks, which is about 1 year.

Hope this helps!

Step-by-step explanation:

[tex]3x - 2/4 - 2x - 5/3 = 1 + x/6\\\\x - x / 6 = 1 + 2/4 + 5/3\\\\5x/6 = 6/6 + 3/6 + 10/6\\\\\frac{5}{6}x = 19/6\\\\x = \frac{19}{6} * \frac{6}{5}\\\\x = \frac{19}{5}[/tex]

Answer:

x = 12

Step-by-step explanation:

Solve:

[tex]\displaystyle \frac{3x-2}{4}-\frac{2x-5}{3}=\frac{1+x}{6}[/tex]

To eliminate denominators, we multiply all terms by the LCM of 4,3, and 6 = 12.

Tammi deposited $520 into a bank account that earned simple interest each year. After 5 years, she had earned $156 in interest.

No money was deposited into or withdrawn from the account.

What was the annual interest rate?

Enter your answer in the box.

Answers

Answer:

6%

Step-by-step explanation:

Interest = Principal * rate * time

      156 = 520(r)(5)

      156 = 2600r

           r = 0.06 or 6%

Answer:

6 percent

Step-by-step explanation:

Interest =1 Part

156 = 520(annual rate )(5)

156 = 2600(annual interest rate )

annual rate=156/2600  

annual interest  rate  = 0.06

annual interest rate=0.06*100

annual interest rate =6%

If you double the radius of a circle, then you will quadruple the circumference of the circle

Answers

Answer:

False

Step-by-step explanation:

No options is attached to the question. However, I'll assume it's a true or false question.

Represent the radius with r.

The circumference is calculated as:

X = 2πr

When the radius is doubled, the new radius R is

R = 2r

And the new circumference, C is:

C = 2πR

Substitute 2r for R

C = 2π * 2r

C = 4πr

Factorize the above equation.

C = 2 * 2πr

Recall X = 2πr;

The expression becomes:

C = 2 * X

C = 2X

This means that the circumference is doubled, not quadrupled.

Hence, the statement is false.

I need the answers for #7 and #8

Answers

Answer:

7. x=9, y=7 The first number is 9, and the second number will be 7.

8. h= $2.25 c= $1.19 The cost of each hotdog is $2.25, and the cost of each bag of chips is $1.19.

Step-by-step explanation:

7. First lets define the variables: x=first number; y=the second number

Now we set up a system of equations:

Eq. 1. 2x+y=25  Eq. 2. 3x-y=20

Now we solve (I'm going to use subsitution you can use wtv you are comfortable with)

1. 2x+y=25      1. y=25-2x

Subsitute.

2. 3x-y=20       2. 3x- (25-2x)=20

Simplify.

3x-25+2x=20        5x-25=20          5x=45      x=9

Now solve for y by subsituting x into one of the equations.

1. 2x+y=25      2(9)+y=25       18+y=25      y= 7

The first number is 9, and the second number will be 7.

8. Define the variables.

h= cost of a hotdog; c=cost of a bag of chips

System of Equations:

Eq. 1. 5h+3c=14.82 Eq. 2. 7h+6c=22.89

Now solve.

1. 5h+3c=14.82  2. 7h+6c=22.89

Using subsitution...

h=2.25 c=1.19

The cost of each hotdog is $2.25, and the cost of each bag of chips is $1.19.

What is an expression?

One mathematical expression makes up a term. It might be a single variable (a letter), a single number (positive or negative), or a number of variables multiplied but never added or subtracted. Variables in certain words have a number in front of them. A coefficient is the number used before a phrase.

Given:

An expression,

48/8 = 42/x

Applying cross multiplication,

x = 42(8)/48

x = 7

Therefore, the value of x is 7.

What is the distance?

Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.

It is given that,500=100x

If the distance is d, velocity is v and time is t then, The formula for the distance is,

Distance = velocity × time

d=vt

The distance is in miles, v is in miles per hour and t is an hour,

miles = miles/hour × hour

The correct representation of the expression is,

If the time in an hour will be x,

An object travels 500 miles at a rate of 100 miles per hour.

Distance = velocity × time

d=vt

500=100x

Thus, the given expression is 500=100x, situations A could match this formula.
