Answer:
10.57 cm²
Step-by-step explanation:
Recall that the area of a triangle is gotten by (1/2)*base*height
If the height of the triangle is 5.45cm and the base is 3.88cm, then the area can be calculated by multiplying the two numbers and dividing it by 2.
5.45*3.88 = 21.146cm²
This still needs to be cut in half (otherwise we are yielding the area of a rectangle with these dimensions)
21.146 cm²/2 = 10.573 cm²
This can be rounded to the nearest hundredth
= 10.57 cm²
159.2, 163.5, 164.1, 171.4, 173.2, 174.3, 174.8, 177.6, 6165.1
mean= 835.9
median= 173.2
mode= N/A
Answer:
Step-by-step explanation:
The scenario is illustrated in the attached photo.
Desiree drove north for 30 minutes at 50 miles per hour.
Distance = speed × time
Distance travelled by Desiree to the north is 50 × 30 = 1500 miles
Distance travelled by Desiree back from the north and to the south is
60 × 20 = 1500 miles
She started from south and drove 1500 miles towards the north. She returned by driving 1200 miles again towards south . Distance of Desiree from where she started will be 1500 - 1200 = 300 miles.
She is 300 miles from her starting position and she is in the southern direction.
Two numbers that can multiply to equal 40 but subtract to equal - 3.
We can replace the inequality with qual sign:
2x - y = 4
x + y = -1
We can combine both question
3x = 3
x = 1
Since we know x = 1, we can solve for y by plug in in either equation:
x + y = -1
1 + y =-1
y = -2
or
2x - y = 4
2(1) - y = 4
-y = 2
y = -2
So the solution of this system of equation is the coordinate (1, -2)
