The length, in inches, of a box is 3 inches less than twice its width, in inches. Which of the following gives the length, l inches, in terms of the width, w inches, of the box?


l = w + 3


l = w + 3


l = w – 3


l = 2w + 3


l = 2w – 3

Answer:

[tex]tanD=\frac{7}{24}[/tex]

[tex]tanF=\frac{24}{7}[/tex]

Step-by-step explanation:

We are given that

ED=24units

EF=7units

FD=25 units

We have to find  the  tangents of the acute angle in the right triangle

We know that

tangent=[tex]\frac{Perpendicular\;side}{Base}[/tex]

Using the formula

[tex]tanD=\frac{EF}{ED}[/tex]

[tex]tanD=\frac{7}{24}[/tex]

[tex]tanF=\frac{ED}{EF}[/tex]

[tex]tanF=\frac{24}{7}[/tex]

Answer: I’m so sorry I don’t understand it but you should try Photomath it’s a app that helps with math and gives answers to math problems. Another good app is Socratic it looks for answers for any subject.

Step-by-step explanation:

To use the angle-angle similarity theorem you need to know 2 corresponding angles of each triangle are the same.

You are already shown that angles H and M are the same.

The sets of corresponding angles are:

H and M, N and I, and O and J

The answer would be angle O and angle J are similar.

Answer:

yes

Step-by-step explanation:

each side is length by with so you can tell these are congruent

Answer:

Yes

Step-by-step explanation:

The reason is because the marks in all of the angles mean the angles are congruent. If the angles match up (1 mark, 2 marks, 3 marks, etc.) then the triangles are congruent.

Answer:

y = 3x - 10

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

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

with (x₁, y₁ ) = (8, 14) and (x₂, y₂ ) = (- 2, - 16)

m = [tex]\frac{-16-14}{-2-8}[/tex] = [tex]\frac{-30}{-10}[/tex] = 3 , then

y = 3x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (8, 14 ) , then

14 = 24 + c ⇒ c = 14 - 24 = - 10

y = 3x - 10 ← equation of line

Regions covered by each functions are shaded and the intersection also shaded and marked.

The white area in the graph is the out of range region.

Answer:

  {(1, 0), (2, 0), (2, 1)}

Step-by-step explanation:

In the attached graph, the dashed lines are to be considered part of the unshaded area, hence in the solution set. The only points with integer coordinates in the solution set are the ones listed above.

Answer:

400 markers.

Step-by-step explanation:

4,000 × ¹/10 = 400.

.Answer:

To calculate a/b of some number c, where a, b, and c are any number, we do the following: a/b x c

Step-by-step explanation:

1/10 x 4,000 = 4,000/10

400 x 10

    10

= 400

= 4 x 100

= 4 x 10 2

400 = 4 x 10 2 markers

Answer:

The speed of the wind is 4.8 km/hr

Step-by-step explanation:

The parameters of the motion of the man are;

The distance the man travels in the given time while moving against the wind = 12 km

The distance the man travels in the giving time while going with the wind = 28 km

From search online for of a similar question, we have;

The speed with which the man is cycling = 12 km/hr

Let. 't', represent the time the travels each distance, let 'w', represent the speed of the wind and let 'v' represent the speed of the man, we have;

Time, t = Distance, d/(Velocity, v)

The resultant speed of the man when he travels against the wing = v - w

The resultant speed of the man when he goes in the the wing = v + w

Therefore, we have;

12/(v - w) = 28/(v + w)

12·v + 12·w = 28·v - 28·w

12·w + 28·w = 28·v - 12·v = 16·v

40·w = 16·v

∴ w = (16/40) × v = (2/5) × v

The speed with which the man is cycling = 12 km/hr

∴ The speed of the wind, w = (2/5) × v = (2/5) × 12 km/hr = 4.8 km/hr

The speed of the wind = 4.8 km/hr.

Step-by-step explanation:

[tex]52 + 78 + x = 180[/tex]

Answer: 4.1 inches

Step-by-step explanation:

From the question, we are informed that New York City is approximately 205 miles from Washington, D.C.

The distance that these cities will appear on a map with the scale 1 in: 50 miles will be represented by x.

Therefore, x:205 = 1:50

Cross multiply

x/205 = 1/50

50x = 205

x = 205/50

x = 4.1 inches

The answer is 4.1 inches

Answer:

average monthly balance = $43

Step-by-step explanation:

If we have a set of N numbers:

{x₁, x₂, x₃, ..., xₙ}

The mean (or average) is calculated as:

Mean = (x₁ + x₂ + ... + xₙ)/N

In this case, the values on the set are the balances for every month.

Then our set is:

{$50, $25, $70, $45, $25}

This is a set of 5 elements.

Then the average monthly balance is:

average monthly balance = ($50 + $25 + $70 + $45 + $25)/5 = $43

average monthly balance = $43

B makes sense.

On the first play, they gained 6 yards.

On the 2nd play, they lost 8 yards, which can be shown as + (-8)

On the 3rd play, they lost two yards, which can be shown as + (-2)

If you input it in a calculator, you'd find that the answer is a negative, which makes sense considering that they lost more yards than they gained.
