The 3 : 7 ratio into which the amount of money is shared by Moira and Non where Non gets $28 more than Moira, indicates;

a) The total amount of money they share is $70

b) The amount Moira gets is $21, while the amount Non gets is 3 : 7

A ratio is a quantitative expression that specifies the number of times a value is contained within another value.

The ratio by which Moira and Non share the money = 3 : 7

The amount Non gets = 28 + The amount Moira gets

Let x represent the amount Moira gets, therefore;

The amount Non gets = 28 + x

The specified ratio indicates;

[tex]\dfrac{x}{28 + x} = \dfrac{3}{7}[/tex]

7·x = 3 × (28 + x)

7·x = 84 + 3·x

7·x - 3·x = 84

4·x = 84

x = 84 ÷ 4 = 21

x = 21

The total amount of money = The amount Moira gets + The amount Non gets

Therefore; The total amount of money = x + 28 + x = 2·x + 28

2·x + 28 = 2 × 21 + 28 = 70

The total amount of money = $70

b) The amount of money Moira gets, x = $21

The amount of money Non gets = $28 + $21 = $49

Step-by-step explanation:

The rate of interest for simple compounding if Louis is offered an interest rate of 6.35% for an investment with continuous compounding, is 0.0515 or 5.15%, so option B is correct.

When the loan is given to you, then some amount is charged to you for the principal amount and that is called interest.

Given:

Eva is offered an interest rate of 5.28% for her savings with simple compounding,

Here, P will be the same, the amount will be the same and the time will be the same,

The amount in simple compounding = The amount in continuous compounding

[tex]p(1 + r)^t = pe^{Rt}[/tex]

Here, R is the rate of interest for simple compounding,

[tex]1 + 0.0528 = e^R[/tex]

1.0528 = [tex]e^R[/tex]

R = ln 1.0528

R = 0.0515

Thus, the rate of interest for simple compounding is 5.15%

The function rule for the total cost of the cookbook is C(x) = 750 + 25x, where x is the number of copies ordered.

# of Copies Ordered Total Cost

100 875

200 1000

300 1125

400 1250

If 400 copies are ordered instead of 100, the total cost would be $1250 instead of $875, saving $375 per book.

The total number of visitors to the zoo that day was 47,750, with 6,780 adults and 40,680 children.

Let a = number of adults

Let c = number of children

a + c = 47,750

c = 6a + 270

Substitute c in the first equation:

a + 6a + 270 = 47,750

7a = 47,480

a = 6,780

Substitute a in the second equation:

c = 6(6,780) + 270

c = 40,680

The total number of visitors to the zoo that day was 47,750, with 6,780 adults and 40,680 children.

Answer:

x and y are inversely proportional , constant of proportion k = 30

Step-by-step explanation:

If x and y are inversely proportional then the equation relating them is

y = [tex]\frac{k}{x}[/tex] ← k is the constant of proportion

multiply both sides by y , then

k = xy

to check that k is constant use the ordered pairs from the table

(0.1, 300 )

k = 0.1 × 300 = 30

(0.5, 60 )

k = 0.5 × 60 = 30

(75, 0.4 )

k = 75 × 0.4 = 30

(100, 0.3 )

k = 100 × 0.3 = 30

thus x and y are inversely proportional with constant of proportion k = 30

Using the ratio provided and the value divided for Jaya and with simple arithmetic, The answer is 6300.

A ratio in mathematics demonstrates how many times one number is present in another. For instance, if a dish of fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six. The ratio of oranges to the overall amount of fruit is 8:14, and the ratio of lemons to oranges is 6:8.

Comparing two integers that each stand for a component of a whole results in a proportion. In essence, a percentage declares that two fractions are equal, regardless of the difference in amount. For instance, the ratio of half of 10 marbles to half of 50 marbles is 10.

ratio = 3:4

Answer:

  -25/(12π) ft/min ≈ -0.663 ft/min

Step-by-step explanation:

You want the rate of change of height of the salt in a cone with height 5 ft and diameter 4 ft, filled 3 ft up from the vertex, and decreasing in volume at the rate of 3 cubic feet per minute.

The rate of change of height is the rate of change of volume, divided by the surface area.

The given cone dimensions tell you the radius is 2/5 of the height of the cone, so the radius of the surface when it is filled to a depth of 3 ft is ...

  r = (2/5)(3 ft) = 1.2 ft

The area of the surface is the area of a circle with this radius:

  A = πr² = π(1.2 ft)² = 1.44π ft²

Then the rate of change of height is ...

  h' = V'/A

  h' = (-3 ft³/min)/(1.44π ft²) = -25/(12π) ft/min ≈ -0.663 ft/min

What is meant by f-test?

In math, f-test refers to carry out the test for the equality of the two population variances.

Here we need to find in which of the three f-tests in a two-way ANOVA do you collapse across the levels of the other factor(s) in computing the means.

As per the definition of f-test, here we know that a two-way ANOVA do you collapse across the levels of the other factor has only two options that is main effect and interaction effect.

As we know that ANOVA separates the within group variance from the between group variance and the F-test is the ratio of the mean squared error between these two groups.

b) The amount of gold edging for a box of 24 plates is of: 904.8 inches.

c) The total cost for the box of 24 plates is given as follows: $29.41.

The gold edging is placed around the circumference of the circular plate, hence the circumference needs to be obtained.

The circumference of a circle of radius r is given by the multiplication of 2π and r, as follows:

C = 2πr.

The radius of the plate in this problem is given as follows:

r = 6 inches.

Hence the circumference of the plate in this problem is given as follows:

C = 2π x 6 = 12π inches = 37.7 inches.

For the box of 24 plates, the amount needed is given as follows:

24 x 37.7 = 904.8 inches.

It costs $3.25 per 100 inches of gold edging, hence the total cost for the 24 plates is obtained as follows:

904.8/100 x 3.25 = $29.41.

the perimeter of a triangle is 49 feet. The triangle's one side is seven feet shorter than its other. the length of each side , Second side: 16 feet, First side: 9 feet,Third side: 12 feet

To find the length of each side of the triangle, we need to start by looking at the perimeter, which is 49 feet.

Perimeter = 49 feet

Second side = 49 - 4 = 45 feet

First side = 45 - 7 = 38 feet

Third side = 45 + 4 = 49 feet

We know that the third side is 4 feet shorter than the second side, so we can subtract 4 feet from the perimeter to find the length of the second side, which is 16 feet. Then, we know that the first side is 7 feet shorter than the second side, so if we subtract 7 feet from the second side we can find the length of the first side, which is 9 feet. Finally, to find the length of the third side, we add 4 feet to the second side, which gives us 12 feet. Therefore, the length of each side of the triangle is 9 feet, 16 feet, and 12 feet.

Answer:

y = -9x + 31

Step-by-step explanation:

We can find the slope of the second line using the formula

[tex]m_{2}=-\frac{1}{m_{1} }[/tex], where m2 is the slope of the second line and m1 is the slope of the first.

Thus, since 1/9 is the slope of the first line, we have

[tex]m_{2}=-\frac{1}{(1/9)} \\m_{2}=-9[/tex]

Since the slope intercept form is y = mx + b, where b is the y-intercept, we need to it in the second line by plugging in (3, 4) for x and y and -9 for m:

[tex]4=-9(3)+b\\4=-27+b\\31=b[/tex]

This is calculated by multiplying the cost of each game (25 cents) by the number of times Larry will have to play (16 times) to last 4 minutes. It will cost Larry $1.00 to last 4 minutes before he is knocked out.

Larry started playing a video game and was knocked out in 30 seconds. He then decided to play again and this time he was able to play 30 seconds longer than the previous game. He kept repeating this and was able to play 30 seconds longer each time. Since it cost him 25 cents to play each game, it will therefore cost him $1.00 to last 4 minutes before he is knocked out. This is calculated by multiplying the cost of each game (25 cents) by the number of times Larry will have to play (16 times) to last 4 minutes. Therefore, 25 cents x 16 = $1.00.
