(C)
Step-by-step explanation:
We are going to use the following conversions for this problem:
1 km = 1000 m
1 hr = 60 min
The key is to multiply the given quantity with factors such that the unwanted units cancel out, leaving only the ones we need. In this case, we need meters and minutes. The set up goes like this:

Answer:
The perimeter of △HFM is 50.75 units
Step-by-step explanation:
The picture of the question in the attached figure
In this problem
Triangles HFM and PST are similar
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional, and this ratio is called the scale factor
step 1
Find the scale factor
Let
z ----> the scale factor

substitute the given values

step 2
Find the perimeter of triangle PST

step 3
Find the perimeter of triangle HFM
we know that
If two figures are similar, then the ratio of its perimeters is equal to the scale factor
so
The perimeter of triangle HFM is equal to the perimeter of triangle PST multiplied by the scale factor
so

Answer:
D. -5, -3
Step-by-step explanation:
-10 / 1/2 = -5
-6 / 1/2 = -3
also / means divided
if you wouldn't mind giving me brainliest, i'm just trying to rank up.
Answer:
32
Step-by-step explanation:
x^2 + 4y = 16 + 20 = 32
Just do substitution.
Hope this helps.
Good Luck
If there are 258 kids total in school, then let’s take it as 100%
And 74 kids have freckles, so we have to find the % of those kids with freckles.
258–100%
74-?%
Let’s find 1% of the kids.
258/100=2.58
Now let’s find the % of 74 kids.
74/2.58=28.68%~28.7%
(The percent of the kids with freckles is 28.7%)
