Answer:

The length of the waterline when hull speed is 4 knots per hour in feet is 2.985 feet.

Step-by-step explanation:

Let the function [tex]h = 1.34\cdot l[/tex], where [tex]l[/tex] is the length of the waterline, measured in feet and [tex]h[/tex] is the hull speed of the boat, measured in knots per hour. If we know that [tex]h = 4\,\frac{kt}{h}[/tex], then the length of the waterline is:

[tex]l = \frac{h}{1.34}[/tex]

[tex]l = \frac{4}{1.34}[/tex]

[tex]l = 2.985\, ft[/tex]

The length of the waterline when hull speed is 4 knots per hour in feet is 2.985 feet.

Answer: -3y+12

Step-by-step explanation:

Answer:

y= 77° x=103°

Step-by-step explanation:

x=103° Alternate angles are equal

y=77° angles on a straight line sum to 180° (180°-103°=77°)

Answer:

For x, we can justify that x=103° and for y, we can justify that it equals 77°.

Step-by-step explanation:

X°: VERTICAL ANGLE THEOREM, or if angles are opposite of each other and are formed by two intersecting straight lines, then they are congruent.

Thus, x°=103°

Y°: SUPPLEMENTARY ANGLE THEOREM, or if two angles are supplementary to the same angle, then the two angles are said to be congruent.

Thus, y°=77°

Answer:

A

Step-by-step explanation:

The solution we're looking at here is a set of all the points between two parallel lines. Let's see what we can find out about those lines from the inequality, and use that the pick the correct option.

We can start by splitting the inequality at the top into two seperate inequalities:

[tex]7\leq y-3x<11\\y-3x\geq7\\y-3x<11[/tex]

From here, we can put each inequality into slope-intercept form:

[tex]y\geq3x+7\\y<3x+11[/tex]

Our slope for both lines is positive, so we can immediately eliminate B and D. A and C both display lines with slopes of 3 and y-intercepts of 7 and 11; the only difference is in which line is dashed and which line is solid.

As a reminder, a dashed line means that the line itself is not included in the solution, a solid line means that it is. Dotted lines always pop up when you see the symbols < and >, while solid lines pop up when you see ≤ and ≥.

[tex]y\geq3x+7[/tex] (Solid)

[tex]y<3x+11[/tex] (Dashed)

This matches up very nicely with the graph in A, our solution.

Answer:

Options (A) and (B)

Step-by-step explanation:

Speed of the leatherback sea turtle = 21.92 miles per hour

If the sea turtle travels distance 'd' in 't' hours,

Speed [tex]=\frac{\text{Distance}}{\text{Time}}[/tex]

Speed that is less than 21.92 mph are 2.192 mph and 20 mph,

For speed = 20 mph

20 = [tex]\frac{d}{t}[/tex]

d = 20t

For speed = 2.192 mph

2.192 = [tex]\frac{d}{t}[/tex]

d = 2.192t

Therefore, Options (A) and (B) are the correct options.

Answer: 15 students

Step-by-step explanation:

From the question, we are informed that there are 150 students in 6th grade, and that 10% earned straight As last quarter.

The number of students that earned straight As will be:

= 10% × 150

= 10/100 × 150

= 0.1 × 150

= 15 students

Answer:

x = 3

Step-by-step explanation:

5x - 3 + 2x = 5x + 3

subtract 5x from both sides

5x - 5x - 3 + 2x = 5x - 5x + 3

-3 + 2x = 3

add 3 to both sides

-3 + 3 + 2x = 3 + 3

2x = 6

divide both sides by 2

2x/2 = 6/2

x = 6/2

x = 3

Answer:

x = 3

Step-by-step explanation:

5x - 3 + 2x = 5x + 3. that is

7x - 3 = 5x + 3 ( subtract 5x from both sides )

2x - 3 = 3 ( add 3 to both sides )

2x = 6 ( divide both sides by 2 )

x = 3

Answer:

Car 1 : 40 miles per gallon

Car 2: 25 miles per gallon

Step-by-step explanation:

family has two cars. During one particular week, the first car consumed 15 gallons of gas. The second car consumed 25 gallons of gas. The two cars Drove a combined total of 1475 miles and the sum of their fuel efficiency was 65 miles per gallon. What were the fuel efficiency of each of the cars that week

Given that :

Fuel efficiency , car 1 = x

Fuel efficiency , car 2 = y

x + y = 65 - - (1)

15x + 35y = 1475 - - - (2)

x = 65 - y

15(65-y) + 35y

975 - 15y + 35y = 1475

20y = 14875 - 975

20y = 500

y = 25

Put y = 25 in (1)

x + y = 65

x + 25 = 65

x = 65 - 25

x = 40
