Eva sees a dolphin 3.2 meters below sea level and a bird 47/10 meters above sea level.

Which of the following expressions represents the vertical distance between the dolphin and the bird?

47/10-(3.2)
3.2-47/10
none of the above

[tex]f(x)=3^x+10x,\ g(x)=5x-3\\\\(f-g)(x)=f(x)-g(x)=(3^x+10x)-(5x-3)\\\\=3^x+10x-5x+3=3^x+5x+3[/tex]

[tex]Answer:\ \boxed{B.\ 3^x+5x+3}[/tex]

Answer:

Transformation : [tex](x,y)\rightarrow (x,-y)[/tex]

Step-by-step explanation:

We are given pre-image is above x-axis abd original figure below x-axis.

As we know y-axis below x-axis always negative. When we translate about x-axis only y value of each coordinate change.

x-coordinates remain same.

Best transformation for below x-axis to above x-axis would be [tex](x,y)\rightarrow (x,-y)[/tex].

For example, (2,-3) change to (2,3)

This is valid to all types of figures which form below x-axis.

You would add the exponents so it'll be 2^3+2^4=2^7 and the same for the bottom which is gonna be -1.

Slope = change in y /change in x

(0, 7), (0, −8)

Slope "m"= -8-7/0-0

M= -15/0

M= undefined

The slope of the line passing through the pairs of points (0, 7), and (0, −8) is not defined.

Here,

We have to find the slope of the line passing through the pairs of points (0, 7), and (0, −8).

What is slope of the line?

A measure of its steepness is called slope of line.

Now,

The points are (0, 7) and (0, -8)

Hence, Slope of the line is calculate as;

[tex]m = \frac{y_{2} -y_{1} }{x_{2}-x_{1} }[/tex]

[tex]m = \frac{-8 -7 }{0}-0 } = \frac{-15}{0}[/tex]

Which is undefined.

Hence, The slope of the line passing through the pairs of points (0, 7), and (0, −8) is not defined.

Step-by-step explanation:

Griffin used $60 on his credit card.

16 - 76 = 60

Final answer:

After applying a $16 credit to the purchase of $76 sneakers, Griffin charged $60 to his credit card.

Explanation:

Griffin has purchased sneakers online. The cost of the sneakers is $76, and he applied a $16 credit towards this purchase. To find out how much Griffin charged to his credit card, we need to subtract the credit from the total cost of the sneakers.

Calculation:
$76 (Total cost of sneakers) - $16 (Credit applied) = $60

Therefore, Griffin charged $60 to his credit card for the sneakers.

Let the number of students in the class be x

Let the number of pieces of gum she gave out be 3x

Equation

3x + 8 = 168 This will not work out evenly. Let's try x - 1. The reason for that is because she may not give out anything to herself.

3(x - 1) + 8 = 168      This doesn't work either.

Well we have to choose. It's a rounding problem.

3x + 8 = 168     Subtract 8 from both sides.

3x = 168 - 8      Combine

3x = 160           Divide by 3 on both sides.

x = 160 / 3

x = 53.333333333

Since that can't be, we could say there were 53 students.

Answer:

Most expensive thing she can afford after 7 years is of worth 2560$

Explanation:

We need to calculate the interest on $2000 at 4% interest per year after 7 year(s).

The formula we'll use for this is the simple interest formula, I = P*r*t, I is the interest after t years, r is interest rate and P is the invest amount.

P = 2000$, r = 4/100 = 0.04, t = 7 years

So , I = 2000* 0.04 * 7 = 560$

Total amount she can retrieve from bank = P+I = 2000 + 560 = 2560$

Most expensive thing she can afford after 7 years is of worth 2560$

Answer:

The answer is (a mountain bike priced at $2,500) In Plato

Step-by-step explanation:

We know, 3 feet = 1 yard.

We have to convert feet to yards to calculate the ratio so that the final answer doesn't have any unit.

Therefore, 21 feet = [tex]\frac{21 feet}{3 feet}yards[/tex] = 7 yards

Thus, the ratio

[tex]\frac{21feet}{8yards} =\frac{7yards}{8yards} =\frac{7}{8}[/tex]

The fraction [tex]\frac{7}{8}[/tex] is already in its simplest form.

Therefore, the given ratio as a fraction in the simplest form without any units is [tex]\frac{7}{8}[/tex]

Final answer:

The ratio of 21 feet to 8 yards simplifies to 7/8 when both measurements are converted to the same units (feet) and the ratio is reduced to simplest form.

Explanation:

To write the ratio of 21 feet to 8 yards as a fraction in simplest form without any units, first, we need to ensure both measurements are in the same unit.

We know that 1 yard equals 3 feet, so 8 yards equal 24 feet. Therefore, the ratio of 21 feet to 8 yards (24 feet) can be written as 21 to 24, which simplifies to 7/8 when dividing both numbers by their greatest common divisor, which is 3.

answer: 24 miles,

15miles/5days = 3 miles/day

8 days * 3 miles/day = 24 miles

OR

5 days = 15 miles

8 days = x miles

x = (15*8)/5 = 24 miles

Remark

The key to this question is to get the original price (36) down to 29.52. In other words, what % will when multiplied by 36 will result in 29.52?

Solution

36 * (x/100) = 29.52   Multiply both sides by 100

36 * x = 29.52 * 100  The 100 on the left disappears.

36 * x = 2952              The decimal disappears. Divide by 36

x = 2952/36

x = 82%

That is not your answer. That just tells you what % of 36 is that would give 29.52

Answer

The % discount is 100 - 82 = 18%. That is the % discount.

Final answer:

The percentage discount on the boots is calculated by first finding the discount amount ($6.48) and then dividing it by the original price ($36.00), which gives us an 18% discount.

Explanation:

To calculate the percentage discount on the boots, we must first determine the amount of the discount. The discount is the difference between the original price and the sale price, which is $36.00 - $29.52 = $6.48.

Next, we calculate the percentage discount using the formula:

Percentage Discount = (Discount ÷ Original Price) × 100%

Substituting in our numbers:

Percentage Discount = ($6.48 ÷ $36.00) × 100%

Percentage Discount = 0.18 × 100%

Percentage Discount = 18%

So, Jeremiah received an 18% discount on the boots.

We can find the midpoint by using the two given coordinates and finding the average between them.

We will find the average between the x coordinates and the y coordinates.

We are given these two coordinates of line segment QR: (-3, 14) and (7, 5). Find the midpoint by finding the average (or mean) between the x coordinates (-3 and 7), and the y coordinates (14 and 5).

Find the average by adding up the two coordinates then dividing the answer you get by 2 (because you added two numbers).

x coordinates average: -3 + 7 = 4, 4/2 = 2; their average is 2

y coordinates average: 14 + 5 = 19, 19/2 = 9.5; their average is 9.5 (or 19/2)

Take the two averages and put them together so your answer is: the coordinate of the midpoint of line segment QR is (2, 19/2).

5(2x +8) = -8x + 4

Use distributive property:

10x +40 = -8x + 4

Subtract 40 from each side:

10x = -8x -36

Add 8x to each side:

18x = -36

Divide both sides by 18:

x = -36 / 18

x = -2

The number is -2
