4. A rocking horse has a weight limit of 60 pounds.
a. What percentage of the weight limit is 33 pounds?
b. What percentage of the weight limit is 114 pounds?
c. What weight is 95% of the limit?

Show your work

Answers

a. 55% of the maximum weight is 33 pounds.

b. 114 pounds is 190% of the weight limit.

c. 57 pounds is 95% of the maximum.

Answer to Part a:

Let c be the weight limit percentage for 33 pounds.

Then we have (60 x c)/100 = 33 pounds

This implies 3c/5 = 33

This means that 3c = 33 x 5 = 165.

This means that c = 165 / 3 = 55.

Therefore 55% of the weight limit is 33 pounds.

Answer to Part b:

Let d be the weight limit percentage for 114 pounds.

Then we have (60 x d)/100 = 114 pounds

This implies 3d/5 = 114

This means that 3d = 114 x 5 = 570.

This means that d = 570 / 3 = 190.

Therefore 190% of the weight limit is 114 pounds.

Answer to Part c:

95% of the weight limit is

= 95 x 60 /100

= 95 x 3/5

= 19 x 3

= 57

Therefore, 95% of the weight limit is 57 pounds.

Find the equation of a line that passes through (1,12) and is parallel to the graph of y=3x+4 . Write the equation in​ slope-intercept form.

Answers

Answer:

y = 3x + 9

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x + 4 ← is in slope- intercept form

with slope m = 3

• Parallel lines have equal slopes , then

y = 3x + c ← is the partial equation of the parallel line

to find c substitute (1, 12 ) into the partial equation

12 = 3 + c ⇒ c = 12 - 3 = 9

y = 3x + 9 ← equation of parallel line

The two shortest sides of a right triangle are 6 and 8 units long, what is the length of the perimeter

Answers

The perimeter of the right angled triangle is 24 units.

The perimeter is defined as the sum of all sides of a polygon. To calculate the perimeter of a triangle we add the length of all the 3 sides of the triangle.

The given side lengths are 6 and 8 units.

We know from Pythagorean theorem that for a right angled triangle the sum of the squares of the legs is equal to the square of the hypotenuse of the triangle.

Hypotenuse is the longest side in a right angled triangle.

Therefore the hypotenuse in this triangle is given by:

Hypotenuse² = 6² + 8²

or, hypotenuse = √(36 + 48) units

or, hypotenuse =√100

or, hypotenuse= 10 units

Now perimeter = (6 + 8 + 10) units = 24 units.

Hence the perimeter of the given right angled triangle is 24 units.

Peanuts: your cost c to buy a p pounds of peanuts at $1.50/lb is represented by c = 1.5p

Is it continuous or discrete

Answers

The given function for peanuts is continuous function.

What is defined as the continuous functions?

A continuous function, as the name implies, refers to one for whom the graph is continuous without a breaks or jumps.

In other words, if we can create the curve (graph) of a function even without lifting a pencil, we can say that function is continuous.In calculus, a function f(x) is considered to be a continuous function at a point x = a if its curve does not break at that point x = a .

For the given expression in the question;

The relation between the cost 'c' and wight 'p' in pounds for the peanuts is given as;

c = 1.5p

As, you can see that the expression is a polynomial having two variables with the highest degree 1.

And, as we know that the every polynomial is a continuous function.

The given function forms a straight line on as for every different real value of p there s single value of c, which varies linearly.

Therefore, the function c = 1.5p is a continuous function forming a straight line.

if 4 liters of a 15% vinegar solution is mixed with x liters of a 30% vinegar solution, the result is a 25% vinegar solution. How many liters of the 30% vinegar solution were mixed ?

Answers

8 liters of 30 percent vinegar solution was mixed.

Percent or percentage is defined as the value for every 100. the simple way to calculate percentage is by dividing the data with the whole data and multiplying it by 100.

4 liters of 15 percent vinegar solution contains:

(15/100)×4 liters of vinegar=0.6 liters

x liters of 30 percent vinegar solution contains:

(30/100)× x liters of vinegar=0.03x liters

Therefore the total vinegar in the 25 percent solution is (0.6+0.3x) liters.

Total volume of the solution is (x+4) liters

(x+4) liters of 25 percent solution contains:

(25/100)×(x+4) liters =(0.25x+1) liters

Now we can equate both values to calculate the value of x from a linear equation:

(0.6+0.3x)=(0.25x+1)

or, 0.05x=1-0.6

or, x= 8 liters

Hence 8 liters or 30 percent solution was mixed.

Monica wants to open a savings account with a deposit of 3,000 monica will not make

Answers

Account Y would earn Monica about $62.70 more interest than account X.

Given Monica deposits $3000.

Bank offers two different savings accounts.

Account X pays 2.1% simple annual interest and Account Y pays 2.4% compounded annually, both for 5 years.

For account X, we have:

Principal (P) = $3000

time (t) = 5 years

rate of interest (r) = 2.1%

we need to calculate simple interest:

Simple interest = P×t×r/100

= 3000c5×2.1/100

= $315

simple interest for 5 years is $315

For account Y, we have:

Principal (P) = $3000

time (t) = 5 years

rate of interest (r) = 2.4%

we need to calculate Compound interest:

compound interest = P×(1₊rate)^time ₋ P

= 3000(1₊2.4/100)⁵ ₋ 3000

= 3000(1.024)⁵ ₋ 3000

= 3000(1.12589907) ₋ 3000

= 3377.69 ₋ 3000

= $377.69

The compound interest for 5 years is $377.7

compound interest of account Y ₋ simple interest of account X

= 377.7 ₋ 315

= $62.70

hence the right option is that account Y would earn Monica about $62.70 more interest than account X.

Vectors! A ship can sail at 30 km/h in still water. The ship heads due north. The water current is flowing at 10 km/h due east.

a) What is the actual velocity of the ship?

b) What direction does the ship sail in?

Answers

Answer:

a) 31.62 km/hb) 18.4° NE

======================

Given

The speed of the ship = 30 km/h,The speed of the current = 10 km/h

A) Actual velocity is found as the sum of two vectors representing the two velocities.

Since the directions are at 90° (N and E), we will use Pythagorean to find the actual velocity.

[tex]v = \sqrt{30^2+10^2}=\sqrt{1000}= 31.62[/tex] km/h (rounded)

The area of the walkway and garden is represented by the expression
2x2 + 12x + 16. Write an expression in factored form that represents
the area of the walkway. Then find the area of the walkway if x is
3 meters. (Hint: Subtract the expression that represents the area of the
garden from the expression that represents the area of both before
factoring.)

Answers

The factorized form of the quadratic is 2*(x + 2)*(x + 4), and when x = 3m, the walkway area is 52 square meters.

How to factorize the area equation?

Here we know that the area is given by the expression:

2x^2 + 12x + 16

To factorize this, we need to find the roots of the quadratic equation, these are the solutions of:

2*x^2 + 12x + 16 = 0

The solutions are given by:

x = (-12 ± √(12^2 - 4*2*16))/(2*2)

x =  (-12 ± 4)/4

The two solutions are:

x = (-12 + 4)/4 = -2

x = (-12 - 4)/4 = -4

Then the factored form is:

y = 2x^2 + 12x + 16 = 2*(x^2 + 6x + 8) = 2*(x + 2)*(x + 4)

Now we want to get the area if the walkway if x = 3, the total area of the walkway and the garden will be:

y = 2*(3 + 2)*(3 + 4) = 70

And the garden measures x by 2x, then if x = 3, the area of the garden is:

a = x*2x = 3*(2*3) = 18

Then the area of the walkway alone is:

70 - 18 = 52

The area of the walkway is 52 square meters.

Fg=14a+1, Fm=14.5 what is a

Answers

The value of a is 2.

A line segment is defined as a measured path between two places. Line segments can make up any polygon's sides because they have a set length.

The figure given below shows a line segment FG, where the length of line segment FG refers to the distance between its endpoints, F and G.

Given that M is the midpoint of FG

FG = 14a + 1 and  FM = 14.5

FG = FM + MG

Since M is the midpoint of FG, So FM = MG

FG = FM + FM

FG = 2FM

Substitute the values of FG = 14a + 1 and  FM = 14.5,

14a + 1 = 2(14.5)

14a + 1 = 29

14a = 28

a = 28/14

a = 2

Therefore, the value of a is 2.
