Answer:
1.73 units
Step-by-step explanation:
The area of a triangle with sides a, b, c and angles A, B, C is given as
Area = 1/2 bc sin A
Given that b=4, c=1, A=120° for a triangle with sides a, b, c and angles A, B, C then the area
= 1/2 * 4 * 1 * sin 120
= 2 sin 120
= 2 * √3/2
= √3
= 1.732
To the nearest hundredth = 1.73
There were 80 runners to start a race. In the first half of the race, 1/5 of them dropped out. In the second half of the race, 5/8 of the remaining runners dropped out. How many runners finished the race
Answer:
24
Step-by-step explanation:
Initially, there were 80 runners in the race. After the first half, 1/5 of them dropped out (given). Therefore, 4/5*80=64 runners remain. In the second half, 5/8 of these 64 runners drop out, meaning 3/8*64=24 runners finished the race.

Cynthia was asked to subtract 0.223 from 0.54. Which of the following is the best estimate that Cynthia can make to check her answer?
A. 0.4 − 0.2
B. 0.5 − 0.2
C. 0.5 − 0.1
D. 0.6 − 0.2
Answer: B
Step-by-step explanation: To find the best estimation to a simple decimal problem such as this one, first round each value to the nearest tenth, hundredth, or thousandth and then subtract. So, for this problem, round each decimal to the nearest tenth.
0.54 - 0.223
0.5 - 0.2

Answer:
slope = - 1
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (2, 8) and (x₂, y₂ ) = (6, 4)
m = [tex]\frac{4-8}{6-2}[/tex] = [tex]\frac{-4}{4}[/tex] = - 1

x=??
Answer:
7
Step-by-step explanation:
Answer:
x = 6
Step-by-step explanation:
Use the Intersecting chord theorem;
Rule: (CE) * (EB) = (AE) * (ED)
CE = x
EB = 15
AE = 9
ED = 10
=> (x) (15) = (9) (10)
15x = 90
Now Divide each side with 15
=> x = 6

Find the area of each semicircle. Round to the nearest tenth. Use 3.14 for Pi. 1. Diameter = 9.4 mm 2. Radius = 3 1/2 ft 3. Radius =8 in
Answer:
34.68 mm^2
19.23 ft^2
100.48 in^2
Step-by-step explanation:
Area of a circle = 0.5 x nr^2
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
0.5 x (9.4/2)^2 x 3.14 = 34.68
0.5 x (3.5)^2 x 3.14 = 19.23 ft^2
0.5 x (8)^2 x 3.14 = 100.48 in^2
Write the equation for a radical function that has been flipped left and shifted down 1.
Answer:
[tex]g(x)=\sqrt{-x}-1[/tex]
Step-by-step explanation:
Let's use the parent function [tex]f(x)=\sqrt{x}[/tex] as an example
Because we are flipping the radical function left, this means [tex]f(x)=\sqrt{-x}[/tex]
Because we are shifting down 1 unit vertically, we have [tex]g(x)=\sqrt{-x}-1[/tex]
Therefore, the final function is [tex]g(x)=\sqrt{-x}-1[/tex]

Alex had 806 dinosaurs. There were 102 Velociraptors, 243 Tyrannosauruses, and the rest were Brontosauruses. There were twice as many eggs as dinosaurs. How many eggs does Alex have?
Answer: 1,612 eggs
Step-by-step explanation:
Alex has a total of 806 dinosaurs. He also has twice as many eggs as he does dinosaurs.
The number of eggs is therefore:
= Number of dinosaurs * 2
= 806 * 2
= 1,612 eggs

Answer:
D
Step-by-step explanation:
A. 9x9 = 81
B. 2x2x2x2x2 = 32
C. 10x10 = 100
D. 5x5x5x5 = 625
Answer:
5⁴ has the greatest value
Step-by-step explanation:
9² = 9 x 9 = 81
2⁵ = 2 x 2 x 2 x 2 x 2 = 32
10² = 10 x 10 = 100
5⁴ = 5 x 5 x 5 x 5 = 624
Therefore, 5⁴ has the greatest value!

The basketball game lasted 1 hour and 40 minutes. If the game started at 7:30 p.m., what time did it end?
(Answer:_:__)
Answer:
9:10pm
Step-by-step explanation:
the game ended at 9:10pm
Answer:
21:10 (24-hour clock) or 9:10 ( 12-hour clock)
Step-by-step explanation:
Two ways it can be solved:
Starting time: 7:30
Game lasted- 1 hour and 40 minutes
Ending time-?
7:30 is converted to 24 hrs timing clock:∴ hr I min
7 : 30 pm
+ 12 : 00
___________
= 19 : 30
Then, hr I min
19 : 30
+ 1 : 40
______________
= 20 : 70
+ 1 : - 60
______________
= 21 : 10
So it ended at 21:10 (24-hour clock) or 9:10 ( 12-hour clock).
or you can just add up :hr I min
7 : 30pm
+ 1 : 40
________
= 8 : 70
+ 1 : - 60
_________
= 9 : 10 pm
