Area of Bull's Eye:

A = π r²

   = π (1)²

   = π

Area of Inner Ring:

A = π r²

   = π (3-1)²

   = 4π

Ratio between Inner Ring and Bull's Eye:

[tex]\frac{InnerRing}{Bull's Eye} = \frac{4\pi }{\pi} = 4[/tex]

Answer: It is 4 times harder to hit the Bull's Eye than it is to hit the Inner Ring

Final answer:

The Inner Ring is 8 times larger than the Bull's Eye.

Explanation:

To determine how much harder it is to hit the Bull's Eye compared to the Inner Ring, we can compare their areas.

The area of a circle is calculated using the formula A = πr^2, where A is the area and r is the radius of the circle.

The area of the Bull's Eye can be calculated as A = π(1)^2 = π square inches.

The area of the Inner Ring can be calculated as A = π(3)^2 - π(1)^2 = 9π - π = 8π square inches.

Therefore, the Inner Ring is 8 times larger than the Bull's Eye.

Subtract both sides by 7.3x

-19.3x - 0.4 > - 39

Add 0.4 to both sides

-19.3x > -38.6

Divide both sides by -19.3 (remember when dividing a negative number, the sign will be flipped)

x < 2

1)

9/2(8 -x) + 36 = 102 - 5/2(3x+24)

Multiply both sides by 2

Distributive propery

72 - 9x + 72 = 204 - 15x - 120

Combine like terms

- 9x + 144 = -15x + 84

Add 15x to both sides

6x + 144 = 84

Subtract 144 from both sides

6x = -60

 x = -10

The weight of the body when the distance is 750 miles if it is inversely proportional is 3,920 pounds.

w = k/d²

Where,

k = constant of proportionality

w = 180 pound

d = 3,500 miles

w = k/d²

180 = k/3500²

180 = k/12,250,000

cross product

k = 180 × 12,250,000

k = 2,205,000,000

Therefore, when d = 750 miles

w = k/d²

w = 2,205,000,000 / 750²

= 2,205,000,000 / 562,500

= 3,920 pounds

Hence, the weight of the body is 3,920 pounds.

Remark

You are dealing with a right angle triangle. You can use one of Sin(x) Cos(x) or Tan(x). Since the Hypotenuse is involved and since you are given the adjacent side, Cos(71) is what you will need.

Solution

H = BC

Cos(x) = adjactent / hypotenuse

Cos(71) = 6.3 / H            Multiply both sides by H

H * Cos(71) = 6.3            Divide by Cos(71)

H = 6.3 / cos(71)             Cos(71) = 0.32557

H = 6.3 / 0.32557          Divide

H = BC = 19.351                       Answer

Answer:

Option B) 5    

Step-by-step explanation:

We are given the following information:

A scatter plot is given which shows the number of hats and scarves each knitter sold at a knitting show.

In the scatter plot the x-axis shows the number of hats sold and the y-axis shows the number of scarves sold.

We have to find the number of hats sold by the knitter when he sold 8 scarves.

In order to find this we have to find the x-values corresponding to the y-values of 8 scarves in the scatter plot.

Corresponding to 8 on y-axis we have a point that have a corresponding value of 5.

Hence, 5 hats were sold by the knitter when he sold 8 scarves.

Option B) 5 is the correct answer.

The scatter plot that shows the number of hats and scarves each knitter sold at a knitting show is Option B) 5    

To find the number of hats sold when 8 scarves were sold, you can look at the scatter plot and observe that there is a data point on the plot where the y-value (number of scarves) is 8, and the corresponding x-value (number of hats) is 5.

In the scatter plot the x-axis shows the number of hats sold and the y-axis shows the number of scarves sold. In order to find this we have to find the x-values corresponding to the y-values of 8 scarves in the scatter plot.

Hence, 5 hats were sold by the knitter when he sold 8 scarves.

4 cups are required

Final answer:

For every cup of butter in the recipe, 4 cups of flour are needed. This is found by analyzing the ratio of flour to butter given in the recipe, which is 2 cups flour to 0.5 cup butter.

Explanation:

The question asks how many cups of flour are needed to mix with each cup of butter according to a given recipe. To determine this, we look at the provided ratios and find that the recipe calls for 2 cups of flour and 0.5 cup of butter. This results in the ratio of 4 cups of flour for every 1 cup of butter.

To calculate the amount of flour required for each cup of butter, we use a simple proportion:

0.5 cup butter : 2 cups flour
1 cup butter : x cups flour

To solve for x (the amount of flour needed for 1 cup of butter), we cross-multiply and get:

0.5x = 2
x = 2 / 0.5
x = 4

So, for every cup of butter, 4 cups of flour are needed.

Answer:

Sali's speed was 18.75 km/h.

Step-by-step explanation:

Jane took 3.5 hours to cycle the 63 km.

As,  [tex]Speed= \frac{Distance}{Time}[/tex] , so the speed of Jane will be:  [tex]\frac{63}{3.5} km/h = 18 km/h[/tex]

Suppose, the speed of Sali is  [tex]x[/tex] km/h

Sali caught up with Jane when they had both cycled 30 km.

So, the time required for Jane to cycle 30 km [tex]= \frac{30}{18}=\frac{5}{3} hours[/tex] and the time required for Sali to cycle 30 km  [tex]=\frac{30}{x} hours[/tex]

Given that, Sali started to cycle 4 minutes or [tex](\frac{4}{60}) or (\frac{1}{15}) hours[/tex] after Jane started to cycle. So, the equation will be.......

[tex]\frac{5}{3}-\frac{30}{x}= \frac{1}{15}\\ \\ \frac{30}{x}= \frac{5}{3}-\frac{1}{15}\\ \\ \frac{30}{x}= \frac{24}{15}\\ \\ 24x=450\\ \\ x= \frac{450}{24}= 18.75[/tex]

Thus, the speed of Sali was 18.75 km/h.

Answer: Single deposit by Edward=$3594 to make it  amount for college=$50,000 in 10 years.

Step-by-step explanation:

Here Compound amount =$50,000

Time=10 years

Rate of interest=4.3%

By the Daily compound  interest formula ,we have

[tex]Amount=Principal(1+rate/365)^{365\times\ time}\\\Rightarrow\ Amount=Principal(1+4.3/365)^{365\times\ 10}\\\Rightarrow\ 50000=P(1+.011)^{3650}\\\Rightarrow\ 50000=P(1.011)^{3650}\\\Rightarrow\ 50000=P(13.911)...........(approx)\\\Rightarrow\ P=\frac{50000}{13.911}=3594......(approx)[/tex]

Therefore Principal amount deposited by Edward is $3594.

Answer:

$32,526.67

Step-by-step explanation:

Let the Principle be P

amount here A= $50,000

time n= 10 years n= 10*365=3650 days

rate of interest= 4.3% compounded daily= 4.3/365

let us use compound interest formula to calculate the principle

[tex]A= P(1+\frac{r}{100})^n[/tex]

putting all the values we get

[tex]50000=P(1+\frac{4.3}{100\times365})^10times365[/tex]

on solving we get P= $32,526.67

therefore he need to deposit $32,526.67

Answer:

Domain = R

Range =(0,infinity)

Step-by-step explanation:

Given a function as

y = 4(1/3)^x

The function does not have x or y in the denominator or any square root sign.

Hence we can assign any values to x.

Domain = R = Set of all real numbers = (-infinity, infinity)

Let us consider range.

We find that 4(1/3)^x is a multiple of 4 and powers of 1/3

Since power of 1/3 is always positive, y cannot take any negative value.

When x=0 y =4.

When x tends to -infinity, y tends to 0

So y cannot take the value 0 except at -infinity.

Range =(0,infinity)

I just took the test. For PLATO the first blank is 30 and the second blank is 2.

Answer:

Part 1) The inequality that describes the relationship between the number of cookies each one of them has is [tex]x^{2} -30x+224\geq 0[/tex]

Part 2) Jessica has at least 2 cookies more than Martha.

Explanation:

Let Jessica has x cookies.

Let Martha has y cookies.

Total cookies they have = 30

Equation forms:

[tex]x+y=30[/tex] or [tex]y = 30-x[/tex]      .....(1)

Each of them ate 6 cookies from their bag.

Cookies left with Jessica = [tex]x-6[/tex]

Cookies left with Martha = [tex]y-6[/tex]

The product of the number of cookies left in each bag is not more than 80.

[tex](x-6)(y-6) \leq 80[/tex]    ....(2)

Substituting [tex]y = 30-x[/tex] in equation (2)

[tex](x-6)(30-x-6) \leq 80[/tex]

=> [tex](x-6)(24-x) \leq 80[/tex]

=> [tex]24x-x^{2}-144+6x \leq 80[/tex]

=> [tex]-x^{2}+30x-144 \leq 80[/tex]

=> [tex]-x^{2}+30x-224 \leq 0[/tex]

Multiplying both sides by -1.

[tex]x^{2} -30x+224 \geq 0[/tex]

Solving this quadratic equation, we get

[tex]x\leq 14[/tex] or [tex]x\geq 16[/tex]

We will take x = 16 (bigger value as Jessica has more cookies)

And y = [tex]30-16=14[/tex]

y = 14

So, Jessica has 16 cookies.

Martha has 14 cookies.

Cookies left in the bag :

Jessica : [tex]16-6=10[/tex] cookies

Martha  : [tex]14-6=8[/tex] cookies

Therefore, Jessica has at least 2 cookies more than Martha.

To simplify the given expression, substitute the values of each square root and simplify the expression to get the final result of 1.416.

To simplify the given expression:
3 times the square root of 5 - 2 times the square root of 7 + the square root of 45 - the square root of 28

We can simplify each square root separately:

√5 = 2.236 (approx.)

√7 = 2.646 (approx.)

√45 = 6.708 (approx.)

√28 = 5.292 (approx.)

Substituting these values in the expression:

3(2.236) - 2(2.646) + 6.708 - 5.292

This simplifies to:
6.708 - 5.292 = 1.416

Therefore, the simplified expression is 1.416.

The predicted yearly supply of hay, in tons, available to each horse in Avery's farm t years from now is given by function F(t); where F(t) = A(t)/H(t)

So, F(t) = [tex]\frac{150(1.5)^{t}}{25(2)^{t}}[/tex] = [tex]6 (\frac{1.5}{2}) ^{t}[/tex] = [tex]6 (0.75)^{t}[/tex] tons/horse

The formula for F(t) in terms of H(t) and A(t) is F(t) = (150(1.5)^t) / (25(2)^t).

To find the formula for F(t), we need to divide the amount of hay produced, A(t), by the number of horses, H(t). So, the formula for F(t) is F(t) = A(t) / H(t). Substituting the given functions, we have F(t) = (150(1.5)^t) / (25(2)^t).

Answer: y + 1 = -2(x + 4)

Point-Slope equation: y - y₁ = m(x - x₁)  ; m is slope and (x₁ ,y₁) is the coordinate

y - (-1) = -2(x - (-4)

y + 1 = -2(x + 4)     simplified (two negatives make a positive)

Answer:

Only one solution

Step-by-step explanation:

Given that there is a coordinate plane (say xy)

Two lines are given.

One line crosses the y axis at 3 and has a slope of negative 1.

hence equation of I line is y = -x+3

The other line crosses the y axis at 3 and has a slope of two thirds.

So equation is y = 2x/3 +3

Since the two lines lie in the same plane and are having different slopes, they intersect at one point.

Eliminate y to get

-x+3=2x/3+3
