Answer:

Interest rate tend to be lower in weak economy than in strong economy to encourage people to borrow money to invest in businesses, the lower the interest rate, the more willing people are to borrow money to make big purchases and this will make economic growth tend to be faster.

Moreso a weak economy tends to have low inflation, so interest rates drop to match.

Answer: x = 10

Explanation: To solve this equation for x, we start by distributing the 2 through the parentheses on the left side.

So we have 2 times x which is 2x and 2 times -3 which is -6. So our equation now reads 2x - 6 = 14.

Solving from here,

we add 6 to both sides of the equation and we have 2x = 20 and dividing both sides by 2, we find that x = 10.

We can check our answer by substituting a 10 back in for x in the original equation and we have 2(10 - 3) = 14.

10 - 3 is 7 so we have 2(7) = 14 or 14 = 14 which is a true statement so our answer checks.

Answer:

(1, - 2 )

Step-by-step explanation:

Given the 2 equations

10x + 6y = - 2 → (1)

2x + 6y = - 10 → (2)

Multiplying (2) by - 1 and adding to (1) will eliminate the y- term

- 2x - 6y = 10 → (3)

Add (1) and (3) term by term

(10x - 2x) + (6y - 6y) = (- 2 + 10), that is

8x = 8 ( divide both sides by 8 )

x = 1

Substitute x = 1 into either of the 2 equations.

Substituting x = 1 into (1)

10(1) + 6y = - 2

10 + 6y = - 2 ( subtract 10 from both sides )

6y = - 12 ( divide both sides by 6 )

y = - 2

Solution is (1, - 2 )

5/20=x/36

1/4=x/36

x=9

9 minutes.

Final answer:

To determine the time Bob spends running, a proportion is set up based on the original 5:20 running to dribbling ratio. Solving this proportion shows that Bob runs for 9 minutes when he spends 36 minutes dribbling.

Explanation:

Bob's practice ratio for running and dribbling is 5 minutes running to 20 minutes dribbling. To find how many minutes Bob spends running when he practices dribbling for 36 minutes, we set up a proportion using the original ratio. The proportion is:

5 minutes running / 20 minutes dribbling = x minutes running / 36 minutes dribbling

To solve for x, we cross-multiply:

(5 minutes running) × (36 minutes dribbling) = (x minutes running) × (20 minutes dribbling)

This gives us:

180 = 20x

Now divide both sides by 20 to solve for x:

x = 180 / 20

x = 9 minutes

Thus, Bob spends 9 minutes running when he practices dribbling for 36 minutes.

Answer:the mean score would decrease more than the median score

Step-by-step explanation:

i did the quiz

Adding a score of 0 would decrease the mean more than the median, with the new mean being 100 and the new median 120.

Adding a score of 0 to the data set of game scores will impact both the mean and the median of the distribution. However, the way each measure of central tendency is affected will be different.

For the mean, which is the arithmetic average, adding a score of 0 will bring the average down. To find the new mean, you would add 0 to the sum of the existing scores and divide by the new total number of scores. Since 0 is lower than any of the existing scores (100, 120, 130, and 150), the mean will decrease.

The initial mean is 125, which is the sum of all the scores (500) divided by the number of scores (4).

Calculating the new mean after including the score of 0, we get (500 + 0) / (4 + 1) = 500 / 5 = 100. This shows the mean would decrease as a result of the 0 score.

As for the median, if we incorporate the score of 0 into the data set, it will become the new lowest score. With an odd number of scores (5), the median will be the middle value.

The scores in order would be 0, 100, 120, 130, and 150. So the new median would be 120. The median is less influenced by extreme values, especially when they are an outlier like the 0 in this case.

Therefore, the correct answer is that the mean score would decrease more than the median score when adding a 0 to the data set.

The tenth value is 15

Solution:

Given that, data set has 9 values

The mean of the set is 5

Number of values = 9 and mean = 5

The mean is given by formula:

[tex]mean = \frac{\text{Sum of terms}}{\text{Number of terms}}[/tex]

[tex]5 = \frac{\text{Sum of 9 terms}}{9}\\\\sum\ of\ 9\ terms = 5 \times 9 = 45[/tex]

When a tenth value is added, the mean becomes 6

Let the tenth value be "x"

New mean is given as:

[tex]6 = \frac{\text{sum of 9 terms} + x}{10}\\\\sum\ of\ 9\ terms + x = 60[/tex]

The tenth value is given as:

sum of 9 terms + x = 60

45 + x = 60

x = 60 - 45

x = 15

Thus the tenth value is 15

Answer:

it's dilation by 2 because the purple one is 2x bigger

Answer:

Step-by-step explanation:

Let, the three islands A, B and C has a, b and c houses respectively.

According to the question, a + b = 15; a + c = 17; b + c = 12; a + b + c = 22.

Adding [ a + b = 15; a + c = 17]-these two, we get, [tex]a + (a + b + c) = 15 + 17 = 32\\a + 22 = 32\\a = 10[/tex].

Now, [tex]a + b = 15\\10 + b = 15\\b = 5[/tex].

[tex]a + c = 17\\10 + c = 17\\c = 7[/tex].

Answer:

Can of Coke

Step-by-step explanation:

Calculate how much money each ounce of drink costs, or the money per ounce ($/oz).

Coke:

$/oz = $1 ÷ 12oz = $0.083333/oz

Pepsi:

$/oz = $1.35 ÷ 16oz = $0.084375/oz

Coke < Pepsi

0.083333 < 0.084375

The calculations show that you would pay more money for one ounce of Pepsi than for one ounce of Coke. Coke costs less than Pepsi.

Therefore the can of Coke is the best buy.

Final answer:

After calculating the cost per ounce for both the Coke and Pepsi, the 12 ounce can of Coke at $1.00 is the better buy as it costs approximately $0.0833 per ounce compared to the 16 ounce bottle of Pepsi at $1.35, which costs approximately $0.0844 per ounce.

Explanation:

To determine whether the can of Coke or the bottle of Pepsi is the better buy, we will calculate the cost per ounce for each.

For the 12 ounce can of Coke priced at $1.00, the cost per ounce is calculated as follows:

Divide the total cost by the number of ounces: $1.00 \/ 12 ounces.

This results in approximately $0.0833 per ounce for the Coke.

For the 16 ounce bottle of Pepsi priced at $1.35, the cost per ounce is calculated in a similar manner:

Divide the total cost by the number of ounces: $1.35 \/ 16 ounces.

You get approximately $0.0844 per ounce for the Pepsi.

Comparing the two, the cost per ounce of Coke is cheaper than the cost per ounce of Pepsi. Thus, the can of Coke is the best buy.

Answer:

The value of 'x' is 7 that will make make L║M.

Step-by-step explanation:

Given,

Line segment L and line segment M are cut by a transversal line.

We can name it as 't' transversal line and also the given angle measures as ∠1 and ∠2.

So, ∠1 = [tex]7x+9[/tex]

∠2 = [tex]8x+2[/tex]

We have to find the value of 'x'.

Solution,

Since L and M are two line segment which is cut by another line segment 't'.

For L║M, the measure of ∠1 and ∠2 must be equal according to corresponding angle property.

"When the measure of a pair of same side corresponding angle is equal, then the line segments are parallel".

[tex]\therefore \angle1=\angle2[/tex]

On substituting the values, we get;

[tex]7x+9=8x+2[/tex]

Combining the like terms, we get;

[tex]8x-7x=9-2\\\\x=7[/tex]

Now we will find out the measure of  ∠1 and ∠2.

[tex]\angle1=7x+9=7\times7+9=49+9 =58[/tex]

[tex]\angle2=8x+2=8\times7+2=56+2=58[/tex]

Hence The value of 'x' is 7 that will make make L║M.

(1)  [tex]1\frac{7}{8}[/tex] pounds of soil   (2) [tex]\frac{35}{2}[/tex]   (3)  33

Solution:

(1) Number of pots = 5

Quantity of soil each pot can hold = [tex]\frac{3}{8}[/tex] pounds

Quantity of soil need to fill all the pots = [tex]5\times \frac{3}{8}[/tex]

                                                               = [tex]\frac{15}{8}[/tex] pounds

                                                               = [tex]1\frac{7}{8}[/tex] pounds

Therefore, [tex]1\frac{7}{8}[/tex] pounds of soil need to fill all of the pots.

(2) To find the product of [tex]4\frac{2}{3}[/tex] and [tex]3\frac{3}{4}[/tex].

Let us first convert the mixed fraction into improper fraction.

[tex]4\frac{2}{3}\times3\frac{3}{4}=\frac{(4\times3)+2}{3}\times\frac{(3\times4)+3}{4}[/tex]

             [tex]=\frac{14}{3}\times\frac{15}{4}[/tex]

             [tex]=\frac{210}{12}[/tex]

This can be simplified. Divide both numerator and denominator by 6.

             [tex]=\frac{35}{2}[/tex]

[tex]4\frac{2}{3}\times3\frac{3}{4}=\frac{35}{2}[/tex]

(3) To evaluate the expression 12x + 6 for [tex]x=2\frac{1}{4}[/tex].

Let us first convert the mixed fraction into improper fraction.

[tex]x=\frac{(2\times4)+1}{4}=\frac{9}{4}[/tex]

[tex]12x+6=12(\frac{9}{4})+6[/tex]

            [tex]=(\frac{108}{4})+6[/tex]

            [tex]=27+6[/tex]

12x + 6 = 33

Answer:

L = 2w

A = L*W

A = 2w*w

A = 2w^2

Step-by-step explanation:

Final answer:

The area of the rectangle garden as a function of its width w is  [tex]A(w) = 2w^2[/tex], where the length is twice the width of the garden.

Explanation:

The landscaper wishes to make a rectangle flower garden where the length is twice the width. If we denote the width as w and the length as 2w, we can express the area A as a function of its width.

The formula for the area of a rectangle is length × width, so the area function A(w) would be:

A(w) = length × width
    = 2w × w
    = [tex]2w^2[/tex]

So, the area of the garden as a function of its width is [tex]A(w) = 2w^2.[/tex]

Answer:

Part 5) Option b [tex]2x\sqrt{3}\ ft[/tex]

Part 6) Option d. [tex]4y\sqrt[3]{2}\ mm[/tex]

Step-by-step explanation:

Part 5) we know that

The area of a square is equal to

[tex]A=b^2[/tex]

where

b is the length side of the square

we have

[tex]A=12x^2\ ft^2[/tex]

substitute

[tex]12x^2=b^2[/tex]

Solve for b

take square root both sides

[tex]b=\sqrt{12x^{2}}[/tex]

Remember that

[tex]12=(2^2)(3)[/tex]

substitute

[tex]b=\sqrt{(2^2)(3)x^{2}}[/tex]

Applying property of exponents

[tex]b=\sqrt{(2^2)(3)x^{2}}=[(2^2)(3)x^{2}]^{\frac{1}{2}}=[2^2x^2]^{\frac{1}{2}}3^{\frac{1}{2}}=2x\sqrt{3}\ ft[/tex]

Part 6) we know that

The volume of a cube is equal to

[tex]V=b^3[/tex]

where

b is the length side of the cube

we have

[tex]V=128y^3\ mm^3[/tex]

substitute

[tex]128y^3=b^3[/tex]

Solve for b

take cubic root both sides

[tex]b=\sqrt[3]{128y^3}[/tex]

Remember that

[tex]128=(2^7)=(2^6)(2)=(2^2)^3(2)[/tex]

substitute

[tex]b=\sqrt[3]{(2^2)^3(2)y^3}[/tex]

Applying property of exponents

[tex]b=\sqrt[3]{(2^2)^3(2)y^3}=[(2^2)^3(2)y^3]^{\frac{1}{3}}=[(2^2)^3y^3]^{\frac{1}{3}}2^{\frac{1}{3}}=2^2y\sqrt[3]{2}=4y\sqrt[3]{2}\ mm[/tex]
