Answer:

Step-by-step explanation:

mow

After applying a 20% discount to the $50 math book, the price becomes $40. Since you have $35, you need to borrow $5 to purchase the book.

To calculate the discounted price of the book, you multiply the original price by the percentage of the discount in decimal form. The discount in decimal form is 0.20 (since 20% = 0.20).

Using the formula for calculating the discounted price:

Discounted Price = Original Price × (1 - Discount Rate)

Discounted Price = $50 × (1 - 0.20) = $50 × 0.80 = $40.

You have $35, so the amount you need to borrow is:

Amount to Borrow = Discounted Price - Amount You Have

Amount to Borrow = $40 - $35 = $5.

Therefore, you need to borrow $5 from your friend to buy the math book.

The original price was $120.00.

30 percent of $120.00 is $36 and if you add those together they equal $156.00.

I hope that makes sense and was helpful.

The identity is 3w + 8 – w = 4w – 2(w – 4)

2w+8=4w−2(w−4)

2w+8=4w−2w+8

2w+8=2w+8

Since both sides equal so it is an identity

Answer:

[tex]t = 23.10\ years[/tex]

Step-by-step explanation:

We have an exponential decay function:

[tex]A = A_0e ^{-0.03t}[/tex]

This function decreases as the years pass. That is, if A is the quantity for a time t and [tex]A_0[/tex] is the original quantity at time t = 0 then:

[tex]A <A_0[/tex]

We want to know for what value of t the value of A decreases by half of  [tex]A_0[/tex]. That is, we want to know when [tex]A = \frac{A_0}{2}[/tex]

Then we do:

[tex]\frac{A_0}{2} = A_0e ^{-0.03t}\\\\\frac{1}{2} =e ^{-0.03t}\\\\ln(\frac{1}{2}) = -0.03t\\\\t = \frac{ln(\frac{1}{2})}{-0.03}[/tex]

[tex]t = 23.10\ years[/tex]

Answer:

slope = [tex]\frac{6}{7}[/tex]

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

where (x₁, y₁ ) = (8, 10) and (x₂, y₂ ) = (1, 4)

m = [tex]\frac{4-10}{1-8}[/tex] = [tex]\frac{-6}{-7}[/tex] = [tex]\frac{6}{7}[/tex]

The slope of the line that passes through the points (8, 10) and (1, 4) is found to be 6/7.

To find the slope of a line that passes through two points, we can use the formula for slope, which is:

slope (m) = (y2 - y1) / (x2 - x1)

Applying this formula to the given points (8, 10) and (1, 4), we get:

slope (m) = (10 - 4) / (8 - 1) = 6 / 7

So, the slope of the line that passes through the points (8, 10) and (1, 4) is 6/7.

Answer:

44

Step-by-step explanation:

first we take the number he gave to his mom and put it to the side for later then we see that 8 bags had 4 candy bars each so 8*4 is 32 then we bring the 12 bars that he gave to his mom and add that to 32 so 32+12 and the answer would be 44

Ross bought a total of 44 candy bars, considering the 12 he gave to his mom and the 32 he divided among the 8 small bags.

To determine how many candy bars Ross bought at the store, we first need to calculate the total number of candy bars in the small bags. Ross divided the remaining candy bars into 8 small bags, with each small bag containing 4 candy bars. Therefore, the total number of candy bars in the small bags is

8 bags x 4 candy bars per bag,

which equals 32 candy bars. However, we must not forget that Ross also gave 12 candy bars to his mom. Thus, the total number of candy bars Ross bought is the sum of the candy bars given to his mom and the candy bars in the small bags, which is

12 candy bars + 32 candy bars,

resulting in 44 candy bars.

The image point of (8,4) after a translation left 2 units and down 4 units is (6,0), obtained by subtracting 2 from the x-coordinate and 4 from the y-coordinate.

The image point of (8,4) after a translation left 2 units and down 4 units would be found by subtracting 2 from the x-coordinate and 4 from the y-coordinate of the original point. A translation does not change the shape or orientation of the figure, it just moves every point of the figure the same distance in the same direction.

To find the new coordinates after the translation:

Therefore, the image point after the translation is (6,0).

Answer:

(- 5, 0), (3, 4)

Step-by-step explanation:

Given the 2 equations

2y - x = 5 → (1)

x² + y² - 25 = 0 → (2)

Rearrange (1) expressing x in terms of y

x = 2y - 5 → (3)

Substitute x = 2y - 5 into (2)

(2y - 5)² + y² - 25 = 0 ← expand parenthesis and simplify

4y² - 20y + 25 + y² - 25 = 0

5y² - 20y = 0 ← factor out 5y from each term

5y(y - 4) = 0

Equate each factor to zero and solve for y

5y = 0 ⇒ y = 0

y - 4 = 0 ⇒ y = 4

Substitute these values into (3) for corresponding values of x

y = 0 : x = 0 - 5 = - 5 ⇒ (- 5, 0)

y = 4 : x = 8 - 5 = 3 ⇒ (3, 4)

Answer:

y=0 or 4, x=-5 or 3

Step-by-step explanation:

First make one unknown in the first equation the subject of the formula.

2y-x=5 will become:x=2y-5

Then in the second equation, wherever there is x we substitute it with 2y-5

(2y-5)²+y²-25=0         (2y-5)(2y-5)+y²-25=0

opening the brackets gives: 4y²-10y-10y+25+y²-25=0

5y²-20y=0

Factorizing the equation we get the following:

y(5y-20)=0

y=0 or

5y-20=0

5y=20

y=4

Thus y=0 or 4

Substitute 0 and 4 for y in any of the equations provided.

Picking the first equation and starting with y=0

2(0)-x=5

x=-5

Using y=4

2(4)-x=5

The solution to the vector equation x + b = c, given vectors B = [8, 4] and C = [22, -9], is x = [14, -13]. This solution is found by subtracting the corresponding entries of the vectors B from C.

To solve the equation x + b = c, specifically with vectors B = [8, 4] and C = [22, -9], you need to use vector subtraction. Applying this operation to the given equation, we have:

x = c - b

By plugging in the given values:

x = [22, -9] - [8, 4]

Subtract the corresponding entries of the vectors:

x = [22 - 8, -9 - 4]

Step-by-step explanation:

Imagine starting by putting the diameter of the semicircle directly in the corner of a square but at a 45 degree angle. That makes a 45-45-90 triangle with the hypotenuse being 50 cm.

Now take the midpoint of this and draw your semicircle. The distance from this point up will be the radius (25 cm). And down will be the side of a triangle with hypotenuse 25. This ends up being 25/√2.

So one dimension would be 25 + 25/√2, and so would the other. Multiplying this together we get:

When the dimensions of a prism are tripled, the scale factor is 3, so the new surface area is obtained by squaring the scale factor and multiplying it by the original surface area. Therefore, the new surface area will be 1548 cm².

The concept in question here pertains to geometric scaling and involves understanding how changes in dimensions affect the surface area of a three-dimensional shape. According to the rules of geometric scaling, when the dimensions of a shape are multiplied by a scale factor, the surface area is multiplied by the scale factor squared.

In this case, the scale factor is 3, so to determine the new surface area when the dimensions of a prism are tripled, you square the scale factor (3² = 9) and multiply it by the original surface area. So, the new surface area = 9 * 172 cm² = 1548 cm².

To find the surface area of a prism, we add up the areas of all its faces. Let's assume the original prism has side lengths x, y, and z. The surface area of the prism is 2(xy + xz + yz). If each dimension is tripled, the new dimensions of the prism would be 3x, 3y, and 3z. Therefore, the new surface area of the prism would be 2(3x3y + 3x3z + 3y3z) = 18(xy + xz + yz).

We need to give the statement that best compares the graph of g(x) with the graph of f(x)

Now, f(x - 4) states that the graph of g(x) is shifted 4 units to the right as compared to the graph of f(x)

Therefore, The statement that best compares the graph of g(x) with the graph of f(x) is : The graph of g(x) is the graph of f(x) shifted 4 units to the right

Hence, The correct option is A. The graph of g(x) is the graph of f(x) shifted 4 units to the right

Answer:

Step-by-step explanation:

The translation is defined as

[tex]G(x)=F(x+a)+b[/tex]                .... (1)

Where, a is horizontal shift and b is vertical shift.

If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.

If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.

It is given that

[tex]G(x)=F(x-4)[/tex]           .... (2)

On comparing (1) and (2) we get

a=-4<0, So the graph of G(x) is the graph of F(x) shifted 4 units to the right.

Therefore, the correct option is A.
