Cameron is flying 8,000 feet above sea level. Directly below her, she sees a whale 50 feet below sea level. Which absolute value expression represents the distance between Cameron and the whale? A) |8,000 − 50| B) |8,000 − (−50)| C) |−8,000 +50| D) |−8,000 − (−50)|

Answers

Answer 1

Answer:

D) |−8,000 − (−50)|

Step-by-step explanation:

When we are dealing with questions involving above or below sea level,

The formula for the Absolute value expression representing the distance = | Height above sea level -(Distance below sea level|

Height of Cameron above sea level = 8000ft = -8000

Distance of the whale below sea level = 50ft = -50

Hence, we have:

|−8,000 − (−50)|.

Option D is the correct option

The equation 12x + 15y = 390 represents the total revenue during a one-day fundraiser. In the equation, x represents the
number of youth T-shirts sold, and y represents the number of adult T-shirts sold. If there were 10 youth T-shirts sold,
how many adult T-shirts were sold?
18 T-shirts
20 T-shirts
24 T-shirts
45 T-shirts

Answers

12x10=120

So, 120+15y=390

390-120=270

So, 15y=270
Therefore, y=18

If there were 10 youth T-shirts sold, then there were 18 adult T-shirts sold.

is the equation y=1/5x+2 is changed to y=1/5x-4, how will graph the line change

Answers

Answer:

The answer to this problem is:

It will shift down 6 units

Step-by-step explanation:

not only have the y-intercept(s) change but also where they are positioned, this is shown in the graphs below.

The graph of the line will shift down by 6 units when the equation y = 1/5x + 2 is changed to y = 1/5x - 4 (option b).

To compare the two equations, y = (1/5)x + 2 and y = (1/5)x - 4, we can focus on their y-intercepts. The y-intercept of the first equation is 2, and the y-intercept of the second equation is -4.

When the y-intercept changes from 2 to -4, the graph will shift vertically. The y-coordinate is decreasing from 2 to -4, which means the graph will shift down by 6 units.

Therefore, the correct answer is:

B) It will shift down 6 units.

Fernando evaluated the expression below. StartFraction 5 (9 minus 5) over 2 EndFraction + (negative 2) (negative 5) + (negative 3) squared = StartFraction 5 (4) over 2 EndFraction minus 10 + 9 = StartFraction 20 over 2 EndFraction minus 10 + 9 = 10 minus 10 + 9 = 9. What was Fernando's error?

Answers

Answer:

Fernando incorrectly found the product of –2 and –5.

Step-by-step explanation:

Fernando evaluated the numerator of the fraction incorrectly.

Fernando simplified StartFraction 20 over 2 EndFraction incorrectly.

Fernando incorrectly found the product of –2 and –5.

Fernando evaluated (negative 3) squared incorrectly.

Fernando's calculation

5(9-5) / 2 + (-2)(-5) + (-3)^2

= 5(4) / 2 - 10 + 9

= 20/2 - 10 + 9

= 10 - 10 + 9

= 9

Correct calculation

5(9-5) / 2 + (-2)(-5) + (-3)^2

= 5(4) / 2 + (10) + 9

= 20/2 + 10 + 9

= 10 + 10 + 9

= 29

Therefore,

Fernando's error was multiplying (-2)(-5) to be equal to -10 instead of 10

Fernando incorrectly found the product of –2 and –5.

HELP!!! Last month, there were 4 sunny days for every rainy day. If there were 30 days in the month, how many days were rainy? Explain your reasoning. If you get stuck, consider using a tape diagram.

Answers

Answer:

6

Step-by-step explanation:

Based on the ratio of sunny days to rainy days last month, there would have been 6 rainy days.

For every 4 sunny days, there is 1 rainy day. This means that every 5 days, one of those days will be rainy and 4 will be sunny.

We can therefore represent that as:

= 1/5 of any number of days will be rainy

If there are 30 days therefore, 1/5 of those 30 days will be rainy:

= 1/5 x 30

= 6 days

In conclusion, 6 days will be rainy out of 30 days.

Maria cut 3/4 yard of ribbon into pieces that are 1/8 yard long. How many pieces of ribbon did Maria cut? don't be a b.*.t.c.h. and not solve it

Answers

Answer:  6 pieces

===============================================

Explanation:

3/4 = 6/8 after multiplying top and bottom of the fraction by 2

She has 6/8 of a yard of ribbon.

If she cuts the ribbon into pieces of 1/8 of a yard each, then she has 6 pieces overall

We can see this if we solve the equation (1/8)x = 6/8. Multiply both sides by 8 to get x = 6.

The number of pieces of ribbon that Maria cut is 6 pieces.

Given,

Maria cut 3/4 yards of ribbon into pieces that are 1/8 yard long.

We need to find how many pieces of ribbon Maria cut.

How do we divide two fractions?

We multiply one fraction with the reciprocal of the other fraction.

Example:

a/b ÷ c/d

= a/b x d/c

= ad/bc

We have,

The total length of the ribbon = 3/4 yards

The length of each piece cut from the ribbon = 1/8 yards.

The number of pieces that can be cut:

= 3/4 ÷ 1/8

= 3/4 x 8/1

= 3x8 / 4x1

= 24 / 4

= 6

Thus the number of pieces of ribbon that Maria cut is 6 pieces.

Continuation of question:The race was over after 10 seconds. The winner of the race is defined by the person who is farthest from the start line. Whose car should be crowned the winner? Use mathematics to justify your answer.Table is attached Solution

Greg

Speed = 13 ft/sStart point = 30.7 ft from start line after 2 seconds

Distance from start line after 10 seconds:

30.7 + 13*(10 - 2) = 30.7 + 13*8 = 30.7 + 104 = 134.7 ft

Marti

Speed = 16.5 ft/sStart point = 2 ft from start line

Distance from start line after 10 seconds:

2 + 10*16.5 = 2 + 165 = 167 ft

Comparing distances from the start line, 134.7 ft vs 167 ft, Marti is farthest from the start line and he is the winner.

Then you set that equal to 3x+72 which would be: 10x+128=3x+72

O E is closer to B than to A.
O E is the same distance from A and B.
plz help me understand this

Answers

Answer:

E is the same distance from A and B. ⇒ D

Step-by-step explanation:

Let us explain the meaning of perpendicular bisector

If line m is the perpendicular bisector of line n, then

line m intersect line n at the mid-point of line nThey form 4 right angles around this mid-point

∵ Line CD is the perpendicular bisector of segment AB

∴ Line CD intersects segment AB at the mid-point of AB

∵ Line CD and segment AB intersected at point E

→ That means E ∈ CD and E ∈ AB

∴ Point E is the mid-point of line AB

∴ Point E divides line AB into 2 equal parts

→ That means point E is at the same distance from points A and B

E is the same distance from A and B.

The pH level of a substance can be determined by the formula pH = –log[H+], where [H+] is the hydrogen ion concentration in moles per liter. An alkaline substance has a pH level between 7 and 14. Which ion concentration corresponds to an alkaline substance?

5.0 x 10^-12
1.0 x 10^-7
1.1 x 10^-4
Please answer asap

Answers

Answer:

B. 5.0 × 10⁻¹² moles per liter.

Step-by-step explanation:

In this exercise we have to calculate the pH levels associated with respective hydrogen ion concentration based on the following formula:

[tex]pH=-\log [H^{+}][/tex]

Where [tex][H^{+}][/tex] is the hydrogen ion concentration, measured in moles per liter.

a) 3.5 × 10⁻¹⁶ moles per liter:

[tex]pH=-\log [3.5\times 10^{-16}][/tex]

[tex]pH \approx 15.456[/tex]

The substance is above the upper bound for alkaline substances.

b) 5.0 × 10⁻¹² moles per liter:

[tex]pH=-\log [5.0\times 10^{-12}][/tex]

[tex]pH \approx 11.301[/tex]

The substance is alkaline.

c) 1.0 × 10⁻⁷ moles per liter:

[tex]pH=-\log [1.0\times 10^{-7}][/tex]

[tex]pH= 7[/tex]

The substance is not acid nor alkaline.

d) 1.1 × 10⁻⁴ moles per liter:

[tex]pH=-\log [1.1\times 10^{-4}][/tex]

[tex]pH \approx 3.959[/tex]

The substance is acid.

Thus, we concluded that correct answer is B.
