Answer:

The actual speed of the car is either 57 mph or 63 mph.

Step-by-step explanation:

Note that 5% of 60 mph is 3 mph.  Thus, the actual speed of the car is between (60 - 3) mph and (60 + 3) mph, or between 57 mph and 63 mph.

The third answer choice is the correct one.

I am at the Kruger National Park in Skukuza with the latitude and longitude coordinates (-24.98,31.58). My friends are exploring
dsp73

Given  Kruger National Park in Skukuza coordinate : (-24.98,31.58).

Nelson Mandela Musuem in Mpumalanga coordinate : (-29.82,31.58).

We need to find exactly in between given coordinates.

We know, mid - point formula :  

\mathrm{Midpoint\:of\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right).

\left(x_1,\:y_1\right)=\left(-24.98,\:31.58\right),\:\left(x_2,\:y_2\right)=\left(-29.82,\:31.58\right)

=\left(\frac{-29.82-24.98}{2},\:\frac{31.58+31.58}{2}\right).

=\left(-27.4,\:31.58\right).

Therefore, will be meeting at (-27.4, 31.58).

tresset_1 [31]

Answer:

m<A > m<B > m<C

Step-by-step explanation:

In triangles, the measure of angles is proportional with the side length's they see,

The angle with the biggest the biggest measure sees the biggest side length

in triangle ABC the side lengths are given as

BC = 14, CA = 13 and AB = 5

from this, we can conclude:

m<A > m<B > m<C

A square has an area of 36 m2. The square is scaled in such a way that its area is increased by 28 m2. What is the approximate f
Naddika [18.5K]

Answer:

The length has increased by a factor of 4/3 or 1 1/3

Step-by-step explanation:

To find the initial length.: root 36.

Root 36 = 6

Then to find the increased version, first find the area: 36 + 28 = 64

Now, the length.

Root 64 = 8

To find the factor it increased by:

6x = 8

x = 8/6 = 4/3

The length has increased by a factor of 4/3 or 1 1/3
