Answer:
How To Find The Area Of The Shaded Region?
Step 1: Find area of inner shape.
Step 2: Find area of outer shape.
Step 3: Area of shaded region = area of outer shape – area of inner shape
Example 2:
Find the area of the shaded region:
area of shaded region
Solution:
Step 1: Find area of inner square = 2 cm × 2 cm = 4 cm2
Step 2: Find area of outer shape = (2 cm × 3 cm) + (10 cm × 3 cm)
= 6 cm2 + 30 cm2
= 36 cm2
Step 3: Area of shaded region = area of outer shape – area of inner square
= 36 cm2 – 4 cm2
= 32 cm2
Step-by-step explanation: There you go :)
Answer:
She shouldn't tip at all since that's a ridiculous concept
Step-by-step explanation:
common sense
SORRY MADE A MISTAKE WITH THE CALCULATOR I KNEW I MESSED SOMETHING UP
The cost of the meal was $22 so that's the price plus tax and tax is 10% of the price so
cost = price + 0.1*price
cost = 1.1 * price
price = cost / 1.1
price = 22 / 1.1 = <u>20</u>
now we need 20% of that so that's
20 * 0.2 = <u>4</u>
If she's simple-minded enough to tip that would amount to <u>$4</u>
Answer:
a) d = 36 ft. ( using Pithagoras´theorem )
b) d = 36 ft ( Using ( function sin ) trigonometry
Step-by-step explanation:
a) Using Pythagoras´Theorem:
Diagonal (d) is the hypothenuse of a right triangle of side 25 feet, and according to Pythagoras´Theorem in a right triangle.
d² = a² + b²
In this particular case a = b = 25 feet then
d² = (25)² + ( 25)²
d = √ 2 * (25)²
d = √2 * 25
d = 1,414*25
d = 35,35
d = 36 ft.
b) Using trigonometry:
We know that sin 45° = cos 45° = √2 / 2
In a right triangle
sin α = opposite side / hypothenuse (d)
sin 45° = √2 / 2 = 25/ d
√2 *d = 2* 25
d = 50/√2
d = 50 / 1,414
d = 35,36
d = 36 ft
Answer:
40 miles per hour
Step-by-step explanation:
From 11:15 to 1:15 it's 2 hours.
They drove 80 miles in 2 hours.
unit rate = speed = distance/time = (80 miles) / (2 hours) = 40 miles per hour
Answer:
4 to 7 is pretty much 4 divided by 7 which = 4/7 and 7/4 is 1 3/4. which is obviously greater. So they both equal different answers.
