Answer:

<u>40 miles in 60 minutes</u>

Step-by-step explanation:

1 hour has 60 minutes, and since the freight train travels 1 mile in 1.5 minutes, it can be said that the train travels 2 miles in 3 minutes (assuming a constant rate). This becomes a problem of equal ratios:

\frac{2}{3}=\frac{x}{60} , <em>where the numerator refers to distance, and the denominator refers to the time</em>

After cross multiplication, we find that 3x = 120, or x = 40.

Therefore, it takes 1 hour for the train to travel <u>40 miles</u>

Answer:

The number of miles will the train travel in 1 hour is 40 miles.

Step-by-step explanation:

Given:

A freight train travels 1 mile in 1 minute 30 seconds.

Find:

The number of miles that the train will travel in 1 hour

Step 1 of 1

One minute 30 seconds is $\frac{3}{2}$ minutes, so the train's speed is

$$\begin{aligned}\text { spced } &=\frac{1 \text { miles }}{\frac{3}{2} \text { minutes }} \\&=\frac{2}{3} \frac{\text { miles }}{\text { minute }}\end{aligned}$$

There are 60 minutes in an hour, so the distance traveled in 60 minutes is distance =(60$ minutes $) \cdot\left(\frac{2}{3} \frac{\text { miles }}{\text { minute }}\right)$

                  =40 miles.

(x + 5)2 + (y - 7)2 = 36, its radius is
sashaice [31]
6 because the 36 is r² where r is the radius, r² = 36; we have to isolate the r so it's by its self, so square root both sides, r = 6

Find the area of the backyard

A=20(14)=280\ yd^{2}

step 2

Find the area of the flower garden

A=5(9)=45\ yd^{2}

step 3

Find the difference

280\ yd^{2}-45\ yd^{2}=235\ yd^{2}

Decide whether quadrilateral ABCD with vertices 4(3,1), B(-1,-1) C(1,3), and D(5.5) is a rectangle, rhombus,square, or parallelo
Sergeeva-Olga [200]

Answer: rhombus

Step-by-step explanation:

By inspection, we can tell that there are no right angles, so we can determine it is not a square or a rectangle.

From the options, it is implied that it is a parallelogram, so to determine if it is a rhombus, we can determine if there is a pair of consecutive congruent sides.

By the distance formula,

AB=\sqrt{(-1-3)^{2}+(-1-1)^{2}}=\sqrt{16+4}=2\sqrt{5}\\BC=\sqrt{(-1-1)^{2}+(-1-3)^{2}}=\sqrt{4+16}=2\sqrt{5}

As AB=BC, there is indeed a pair of consecutive congruent sides, and thus the most specific classification is a <em>rhombus</em>
