The answer is 5sqrt2 or 7.07
Since you have one 45 degree angle the other angle is also 45 degrees. This gives you a right isosceles triangle.
This can be solved using Pythagorean theorem or trig ratios.
a^2+a^2= 100
2a^2 = 100
a^2=50
a= sqrt 50
a=5sqrt2
Answer:
No, see below.
Step-by-step explanation:
10% of 150 is .1 times 150= 15
15+75=90
So, Jordan is incorrect.
Rhombus , 4 sides are equal
so
AB = √(15^2 +20^2)
AB = √(225 + 400)
AB = √625
AB = 25
P = 4a
P = 4(25)
P = 100
answer
H. 100 in
Answer:
Sheldon has to sell at least 143 cups of coffee to purchase the kayak.
Step-by-step explanation:
First write an expression:
15 + 0.25x ≥ 50.75
Next use inverse operations:
15 + 0.25x - 15 ≥ 50.75 - 15
0.25x ≥ 35.75
0.25x ÷ 0.25 ≥ 35.75 ÷ 0.25
x ≥ 143
Sheldon has to sell at least 143 cups of coffee to purchase the kayak.
I hope this helped and if it did I would appreciate it if you marked me Brainliest. Thank you and have a nice day!
7.8 * 10^5=since the exponent is positive 5. Then the 7.8 you move the decimal 5 places to the right to be
780000
