$\huge\boxed{Hello!:)}$

Combine like terms:

4x+3x=7x

Remember, we can add terms with the same variable together, but we can't add terms with different variables.

$\huge\boxed{Hence,\:the\:answer\:is\:7x.}$

$\huge\underline{Hope\:it\:helps!}$

A rectangle has a perimeter of 165.4 kilometers and a height of 20 kilometers. What is the length of the base?

KATRIN_1 [288]

Answer: Follow the Steps Below.

Step-by-step explanation: Simply divide the area of the rectangle by its height to find its base. Other forms of solving for the base can be accomplished knowing diagonal length by simply taking the square root of the diagonal length squared minus its height squared.

Suppose a hurricane traveled 130 miles from point in the Atlantic Ocean to Florida coastline in 6 1/2 hours. How many miles per

Marizza181 [45]

Answer:

The hurricane traveled 260 miles per hour.

Step-by-step explanation:

Given,

Distance covered by hurricane = 130 miles

Then time = $\frac{6}{12}$ hours= $0.5$ hour

Distance=Speed*Time

Speed= $\frac{Distance}{Time}$
Speed= $\frac{130}{0.5}$

Speed=260 miles per hour

So, the hurricane traveled 260 miles per hour

The rate at which a body cools also depends on its exposed surface area S. If S is a constant, then a modification of (2), given

padilas [110]

Answer:

76.25°

Step-by-step explanation:

The solution to the differential equation is an exponential curve with a horizontal asymptote at Tm. It passes through (0, 145) and (30, 95), so the equation can be written as ...

T = 80 +65((95-65)/(145-65))^(t/30)

T = 80 +65(3/8)^(t/30)

That is, the temperature difference is reduced to 3/8 of its original value in 30 minutes.

Since the coffee in cup B cools twice as fast, it will cool to the same temperature (95°) in 15 minutes. In the next 15 minutes, the temperature difference will be reduced to (3/8)^2 of the original 80°, so will be 11.25°. That is, the temperature of cup B will be ...

11.25° +65° = 76.25°

after 30 minutes.
