Which set of three angles could represent the interior angles of a triangle?
19 degrees, 70 degrees, 91 degrees
47 degrees, 12 degrees, 31 degrees
50 degrees, 20 degrees, 20 degrees
25 degrees, 25 degrees, 100 degrees
Answer:
19 degrees, 70 degrees, 91 degrees
Step-by-step explanation:
to make an interior angle of a triangle you need to make a 180-degree triangle and 19+70+91 make 180 degrees
Answer:
19, 70, 91
Step-by-step explanation:
19 + 70 + 91 = 180. Everything else doesn't add up to 180.
=) Asif deposits $650 into a bank paying a simple interest. He leaves the money there
for 5 years. At the end of the 5 years, the amount in the bank is $763.75.
Calculate the percentage rate of interest the bank paid per year.
Answer:
interest he got per year is 22.75
Step-by-step explanation:
deposited money = 650
after 5 years = 763.75
interest he got = 763.75 - 650
= 113.75
interest he got each year = 113.75 / 5
= 22.75

a man in a boat rowing from light house whose height is 200 meter.he takes 2minutes to change the angle of elevation top of light house from 60⁰ and 45⁰ find speed of boat
Answer:
The speed of the boat is approximately 0.704 m/s
Step-by-step explanation:
The time it takes the man in the boat to change the angle of elevation from 60° to 45°, t = 2 minutes = 120 seconds
The height of the light house = 200 m
Given that the angle of elevation is reducing, the direction of the man is away from the lighthouse
The initial distance of the man in the boat from the lighthouse = 200 m/(tan(60°)) = (200/√3) m
The final distance of the man in the boat from the lighthouse = 200 m/(tan(45°)) = 200 m
The distance traveled in 2 minutes, d = 200 m - (200/√3) m ≈ 84.53 m
The speed of the boat, v = d/t
∴ v = 84.53 m/(2 min × 60 s/min) ≈ 0.704 m/s
The speed of the boat, v ≈ 0.704 m/s.

Bruce is 4 times as old as Indy. 6 years ago, Bruce was 6 times as old as Indy. How old is bruce?
Answer:
60
Step-by-step explanation:
Bruce is 4 times as old as Indy
b = 4i
6 years ago, Bruce was 6 times as old as Indy
b - 6 = 6(i - 6)
b - 6 = 6i - 36
Substitute for b = 4i
4i - 6 = 6i - 36
Subtract 4i from both sides
-6 = 2i - 36
Add 36 to both sides
30 = 2i
Divide both sides by 2
15 = i
Since b = 4i
b = 4(15)
b = 60

WILL GIVE BRAINLIEST: What is the local minimum value of the function g(x)=x^4-5x^2+4? (Round answer to the nearest hundredth)
Answer:
Step-by-step explanation:
you can find where the first derivative is 0 to find the critical points
g'(x) = ( x^4 -5x^2 +4)' = 4x³-10x
g'(x) =0, make y =0 to find find where g'(x) is 0
4x³-10x =0 , factor 2x
2x(2x²-5)= 0 , each factor must be 0
2x= 0, so x= 0
2x²-5 =0, so x = ±√5/2
we now have 3 critical points -√5/2, 0, and √5/2
make intervals (-∞, -√5/2), (-√5/2, 0) , (0, √5/2) and (√5/2, +∞)
pick a point to test on each interval: -2, -1, 1 and 2 for example, and
calculate g'(x) = 4x³-10x at those points
for x= -2 we have 4(-2)³-10(-2) = -12 , negative number, decrease
for x= -1 we have 4(-1)³-10(-1) =6, positive number, increase
for x= 1 we have 4(1)³-10(1) = -6, negative number, decrease
for x= 2 we have 4(2)³-10(2) = 12, positive number, increase
we went from a decrease to an increase on intervals (-∞, -√5/2), (-√5/2, 0) so x= - √5/2 ≈ -1.58 is a minimum
we went from a decrease to an increase on intervals (0, √5/2), (√5/2, +∞) so
x= √5/2 ≈ 1.58 is a minimum as well

x3 + 5y when x = 4, y = -3
Answer:
49
Step-by-step explanation:
4^3=64
5(-3)=-15
64+(-15)=49
Answer:
49
Step-by-step explanation:
First, because of the order of operations, you would do 4^3 (or four to the power of three) first to get 64. 5×-3 is equal to -15, and a positive number plus a negative number is just that positive number minus a positive version of the negative number, if that even makes sense. Basically, 35 + -2 would be equal to 35-2. 64-15 is equal to 49, which is your answer!
I hope this helped you!

Step-by-step explanation:
Method 1:

9 oranges = x
1.40 / 4 = 0.35
This is 0.35 per orange
0.35 x 9 = 3.15
$3.15
Method 2:
1.40/4 = x/9
12.6 = 4x (cross multiply 9 and 1.4 and cross multiply 4 and x)
x = 12.6 / 4
x = 3.15

1039 85.9
1156 87.2
1218 87.8
1131 91.4
888 75.5
Using technology, the regression model obtained will be in the form :
y = bx + c
b = slope ; c = intercept
y = temperature ; x = chirps per minute
The regression model is :
ŷ= 43.28 + 0.0390x
If outside temperature, y = 76 ; x will be ;
76 = 43.28 + 0.0390x
76 - 43.28 = 0.0390x
32.72 = 0.0390x
x = 32.72 / 0.0390
x = 838.97435
x = 834 chirps per minute
