First we need to find Mia's speed (v) in km/min
v = distance travelled/ time
v = 3 km/20 minutes
v = 0.15 km /min
in order to convert the speed into mile/min, we need to use the conversion factor given in which for every kilometer, there is 0.6 miles.
v = 0.15 km/min *(0.6 miles/ km)
v =0.09 miles/min
therefore the speed in miles/min is 0.09 miles/min
Answer:
Step-by-step explanation:
16% is the answer.
440 is what percent of 2750?
440 = x/100 x 2750 (of means x or times in math)
440 = 2750x/100
440 = 275x/10
440x10 = 275x/10
4400 = 275x
4400/275= 275x/275
4400/275 = x
4400/275 = 16%
Answer: 12a=48
Step-by-step explanation:
4a+6b=10
4a=10-6b
a=(10-6b)/4
a=(5-3b)/2
2a-4b=12
2((5-3b)/2)-4b=12
(5-3b)-4b=12
5-7b=12
-7b=7
b=-1
2a-4b=12
2a-4(-1)=12
2a+4=12
2a=8
a=4
a=4, b=-1
12a=48
Answer:
2
Step-by-step explanation:
The equation is mx+b=y
The equation is not simplified yet.
2y-4x=1
Add 4x to both sides
2y=1+4x
Divide by 2
1/2+2x
For this just identify. M=slope. The number next to the x is 2. So the answer is 2
Answer: 294√3
Explanation:
1) The described hexagon has these featrues:
a) 6 congruent equilateral triangles whose side lengths measure 14
b) height of each triangle = apotema = a
c) the area of each triangle is base × a / 2 = 14 × a / 2 = 7a
2) a is one leg of a right triangle whose other leg is 14 / 2 = 7, and the hypotenuse is 14.
3) Then you can use Pythagorean theorem fo find a:
14² = 7² + a² ⇒ a² = 14² - 7² = 147 ⇒ a = √ 147 = 7√3
4) Therefore, the area of one triangle is: 14 × 7√3 / 2 = 49√3
5) And the area of the hexagon is 6 times that: 6 × 49√3 = 294√3
