Answer:

30 minutes

Step-by-step explanation:

The hare and tortoise meet in 30 minutes at 240 feet.

Answer:

30minutes

Step-by-step explanation:

Tortoise = Hare

2m + 180 = 8m

collect like terms

180 = 8m - 2m

180 = 6m

divide both sides by 6

m = 180/6

m = 30

It will take 30 minutes for the tortoise and hare to meet.

ordered pairs are (x,y) meaning the first value in the ordered pair would be the value you find on the x axis (horizontal) and the second value in the ordered pair would be the value you find on the y axis (vertical).

Answer:

A. All four sides must be congruent.

Step-by-step explanation:

A quadrilateral has four sides. A rhombus has four equal sides, which are congruent. The angles can be different. It doesn't have four lines of symmetry. One triangles sums to 180 degrees not 4. 4 triangles would sum up to 720 degrees

Answer:

9 months

Step-by-step explanation:

Given data

One time fee= $140

Monthly fee= $40

Total amount of check = $500

The expression that describes the situation is given as

y=mx+c

where y= the total amount of the check

m= the monthly fee

x= the number of months

c= the one time fee

Substitute

500=40x+140

500-140=40x

360=40x

x= 360/40

x=9

Hence the number of months is 9 months

The lines which are perpendicular to 3x + 6y = 5 are; Choice B and C; y = 2x - 1 and y - 4 = 2(x + 7).

From the task content, it follows that the given equation is; 3x+ 6y = 5.

By rewriting the equation in slope intercept form; it follows that; y = (-1/2)x +5/6. Hence, the slope of the line is; -1/2.

From line geometry, it follows that two lines are perpendicular if; m1 × m2 = -1.

Therefore, a line perpendicular to the given line will have a slope of 2.

From the given option, the lines which are perpendicular to 3x + 6y = 5 upon conversion to the Slope-intercept form are; Choice B and C.

x=2 and y=1

Step-by-step explanation:

Rewrite equations:

y=−x+3;y=x−1

Step: Solve

y=−x+3

Step: Substitute−x+3foryiny=x−1:

y=x−1

−x+3=x−1

−x+3+−x=x−1+−x(Add -x to both sides)

−2x+3=−1

−2x+3+−3=−1+−3(Add -3 to both sides)

−2x=−4−2x−2=−4−2

(Divide both sides by -2)

x=2

Step: Substitute2forxiny=−x+3:

y=−x+3

y=−2+3

y=1(Simplify both sides of the equation)

Answer: C. [tex]265.9^{\circ}F[/tex]

Step-by-step explanation:

Given: The formula below can be used to find D, the difference in temperature between the pan and the room after t minutes.

[tex]D = 338e^{-0.03t}[/tex]

At t= 8 minutes, we get

[tex]D = 338e^{-0.03(8)}\\\\\Rightarrow\ D = 338e^{-0.24}\\\\\Rightarrow\ D = 338(0.786627861067)\\\\\Rightarrow\ D = 265.88\approx265.9^{\circ}F[/tex]

Answer:

11.6m

Step-by-step explanation:

A 13.5​-m fire truck ladder is leaning against a wall. Find the distance d the ladder goes up the wall​ (above the fire​ truck) if the ladder makes an angle of 59 22' with the horizontal.

We solve the above question using the Trigonometric function of Sine.

sin θ = Opposite/ Hypotenuse

Hypotenuse = Length of the ladder = 13.5m

Opposite = d

θ = 59° 22'

= 59° + 22/60

= 59° + 0.367

= 59.367°

Hence,

sin 59.367 = d/13.5m

d = sin 59.367 × 13.5m

d = 11.616057416m

Approximately = 11.6m

Therefore, the distance d the ladder goes up the wall is 11.6m

Answer:

Obtuse are a bit slanted Right angles are Shaped like an L

Answer:

Obtuse

Step-by-step explanation:

This is an obtuse triangle. Because the degrees of the angle is more than 90 degrees. A right triangle's degrees is 90 exactly and usually has a square marking the angle, an acute is less than 90 degrees for the angle.

y - 7 = -5x - 30

y = -5x - 23

Answer:

1. Consider a hot pot taken off the stove and placed on a tile countertop. At first it cools quickly. As it cools, the difference in temperature between the pot and the room air becomes less, and so it takes a long time for the pot to lose enough heat to match room temperature. Two objects at the same temperature are said to be in equilibrium.

2.  When a liquid changes into a gas it absorbs energy. When it changes into a solid it gives off energy...If a solid (dry ice for example) is allowed to sublimate into a gas, it absorbs heat - that's why it feels cold when you touch ice. So, if a gas changes into a liquid, it give off heat as an opposite effect.  Anytime you compress a gas, it gets warmer.

To answer this question, you could use algebra.

If the number of cheeseburgers was three times the number of hamburgers, we could write this as.

Cheeseburgers= 3x and Hamburgers = x

We can then write an expression for the total number of burgers.

4x = 352

Divide both sides by four.

x = 88

Because hamburgers = x in relation to the cheeseburgers, that would mean the number of hamburgers sold on monday was 88.
