Answer:

12.3 mph

Step-by-step explanation:

Let x be our speed now

We increase the speed by 5.6 mph

Our new speed is x+5.6

We are going 17.9 mph

x+5.6 = 17.9

Subtract 5.6 from each side

x+5.6 -5.6 = 17.9-5.6

x =12.3

Match each circular flower bed on the left to its circumference and its area on the right. Some answer options on the right will
marin [14]

Answer:

Bed A --- Third Option

Bed B --- Fifth Option

Step-by-step explanation:

Flower Bed A)

The formula for circumference is:

C=2\pi r

The diameter of A is 10 feet. So, its radius is 5 feet.

Substitute 5 for r. So, the circumference of Bed A is:

C=2\pi (5)=10\pi\text{ feet}

The formula for the area of a circle is:

A=\pi r^2

Substitute 5 for r:

A=\pi (5)^2

Square and simplify:

A=25\pi \text{ square feet}

So, the circumference of Bed A is 10π feet and its area is 25π square feet.

Therefore, match Bed A to the third option.

Flower Bed B)

The radius of Bed B is 6 feet. Again, we can use the circumference and area formulas. Substitute 6 for r for circumference:

C=2\pi (6)

Multiply:

C=12\pi\text{ feet}

Substitute 6 for r for the area formula:

A=\pi(6)^2

Square and simplify:

A=36\pi\text{ square feet}

So, Bed B has a 12π feet circumference and a 36π square feet area.

Therefore, match Bed B to the fifth option.

And we're done!

Hi... So for this homework question It says " Amy bought 2 and 1/2 gallons of paint for $60. What is the cost for 1 gallon of pa
andrey2020 [161]

I'm sorry but the solution you proposed was a bit hard to follow, so I'll just post my solution: we convert "2 and 1/2" to a single fraction:

2+\dfrac{1}{2} = \dfrac{4}{2}+\dfrac{1}{2}=\dfrac{5}{2}

So, we know that 5/2 gallons cost 60 dollars, which means

\dfrac{5}{2}g=60

To find the cost of a single gallon, we have to solve the equation for g:

g = 60\cdot \dfrac{2}{5} = 24
