Answer: B. 25.2 units
Step-by-step explanation:
The kite consists of 4 right angle triangles. The two smaller right angles are equal. Also, the two bigger right angles are equal.
To determine the hypotenuse of each triangle, we would apply Pythagoras theorem which is expressed as
Hypotenuse² = opposite side² + adjacent side²
Considering the smaller triangle,
Hypotenuse² = 4² + 3² = 16 + 9 = 25
Hypotenuse = √25 = 5
Considering the smaller triangle,
Hypotenuse² = 7² + 3² = 49 + 9 = 58
Hypotenuse = √58 = 7.616
The perimeter of the kite is the sum of the length of each side. Therefore,
Perimeter = 5 + 5 + 7.616 + 7.616 = 25.2 units to the nearest tenth
Answer:
4. option A ---> m = 65h
Step-by-step explanation:
According to the question it states that,
- m --> number of miles traveled.
- h --> <u>over</u> hours
Now if we look at the table we need to find the starting point, or in other words, how much distance traveled in 0 hours. So we would divide miles / hours.
*Four hours, the variable in the question and in the table says n, but the answer choices says h, so I am saying h for hours just if you were wondering on it.*
distance (m) / hours (h)
130 / 2 = 65
195 / 3 = 65
325 / 5 = 65
455 / 7 = 65
So, our starting point, or numbers of miles traveled in 0 hours was 65. Now let us form an equation.
m = 65h
I would appreciate if you give me the brainlist or not. Hope this helps and stay safe, happy, an healthy, thank you :) !!
Answer:
B: -1 × 2 × -3 × 4 × -5
Step-by-step explanation:
-1 × 2 × -3 × 4 × -5
= -120
Hi Braniac
S = his speed for the 1st 20 mi
(s-2) = His speed for the last 16 mi
We know that :
time= distance/ speed
initial time = cool down time
20/s = 16/(s-2)
Now cross multiply
20(s-2) =16s
20s-40=16s
20s-16s=40
4s = 40
Now we need to divide both sides by 4 so we can find the speed
4s/4 = 40/4
s= 10 mph
His initial speed is 10mph
Now let's find his cool down speed
10-2 = 8mph
His cool down speed is 8mph
I hope that's help :)
If you have any questions please let me know :)
