Answer:

120 \frac{4}{5} or 120.8 miles per hour

Step-by-step explanation:

We first convert the distance into an improper fraction to facilitate calculation.

90 \frac{3}{5} = \frac{90\times 5 + 3}{5} = \frac{453}{5}

Average speed

= distance/time

= \frac{\frac{453}{5}}{\frac{3}{4}}miles per hour

= \frac{453}{5} \times \frac{4}{3} miles per hour

= \frac{604}{5} miles per hour

= 120 \frac{4}{5} miles per hour or 120.8 miles per hour

Which step should be used to prove that point P is equidistant from points R and Q
nydimaria [60]

Step-by-step explanation:

1.  If any one side and any one common angle are equal in triangles PQR and PRS, then their corresponding sides are also equal.

2. If two sides and one included angle are equal in triangles PQS and PRS, then their third sides are equal.

3.  In triangles PQR and PQS, if one side and one angle are equal, then their corresponding sides and angles are also equal.

4. In triangles PRS and PQS, all three angles are equal.

Answer:

UV corresponds to RS.

\angle R corresponds to \angle U

Step-by-step explanation:

Given

\triangle SRQ and \triangle VUT

Transformation: Rigid

Required

Determine the true options

When a rigid transformation occurs from SRQ to VUT, the following are the corresponding sides:

SR to VU, SQ to VT, RQ to UT

And the corresponding angles are:

<S to <V, <R to <U and <Q to <T

From the corresponding sides above, we have:

SR to VU

Rewrite:

RS to UV

Hence: (c) is correct

From the corresponding angles above, we have:

\angle R to \angle U

Hence:

(b) is correct
