Answer:
Step-by-step explanation:
Given triangle is right isosceles since one of the angles is 45°
Let the AC = x, then BC = x and AB is:
- x² + x² = 5²
- 2x²=5²
- x²= 5²/2
- x = 5/√2
- x = 5√2/2
Correct option is D
Answer:
a). total length of rope=132 m
b). total cost of the rope=$528
Step-by-step explanation:
Step 1
To get the total length of rope needed to cover the circular garden twice, we express this as;
P=πD
where;
P=perimeter
π=pi
D=diameter
In our case;
π=22/7
D=21 m
replacing;
P=(22/7)×21=66 m
2×P=2×66=132 m
total length of rope=132 m
Step 2
The expression to calculate the total cost can be written as;
total cost=cost per meter length×total length of rope
where;
cost per meter=$4
total length of rope=132 m
replacing;
total cost=4×132=$528
total cost of the rope=$528
Answer:
Therefore, the angle 3 have 28 degrees.
Step-by-step explanation:
We know that the lines a and b are parallel. When they are cut by transversals, they form a triangle. Parallel lines a and b are cut by transversals s and t to form a triangle. Angle 1 is 90 degrees, angle 2 is 62 degrees.
We know that the number of degrees in a triangle equals 180.
We get:
Therefore, the angle 3 have 28 degrees.
Answer:
0.7 pounds of fruit
Step-by-step explanation:
Step 1. Add all fruit Ashley has been given to Aliyah, Brendan and Arley
Find the sum of;
1.3 pounds for Aliyah
2.4 pounds for Berndan
<u> 1.2 pounds for Arley </u>
4.9 pounds of fruits
Step 2. Subtract the total pounds given from the total pounds of fruit Ashley had.
5.6 pounds - 4.9 pounds = 0.7 pounds left
Answer; Ashley has 0.7 pounds of fruits left
