Please tell the answer
Answer:
Step-by-step explanation:
The person I sent it to couldn't see it either. I'm going to take a chance and say the Chord (AB) and the Tangent line form a 50 degree angle. If this is incorrect, I won't know, from the diagram, what else to try.
If I'm right then <OAB = 40 degrees because 90 - 50 = 40 because <AOC is a right angle (property of radii and tangents).
<ABO also = 40 (the triangle is isosceles by two legs being radii).
That means that BOA = 180 - 40 - 40 = 100

Answer:
[tex]6\frac{7}{10}x + 9[/tex]
Step-by-step explanation:
Step 1: Distribute
[tex]3(\frac{7}{5}x + 4)-2(\frac{3}{2}-\frac{5}{4}x)[/tex]
[tex](3*\frac{7}{5}x) + (3 * 4) + (-2 * \frac{3}{2}) + (-2 * -\frac{5}{4}x)[/tex]
[tex]\frac{21}{5}x + 12 + \frac{-6}{2} + \frac{10}{4}x[/tex]
Step 2: Combine Like Terms

5 members or 20% of the math league did not come to the meet. how many total members are there
Please Help! One natural number is 4 more than the other one. The product of the two numbers is three times the square of the smaller number. Find the numbers.
Let n and n+4 be the numbers. Then:
n² + 3(n+4)=66
n²+3n-54=0
(n+9)(n-6)=0
n=6 or -9
n+4=10

2. Bryan wants to rent a boat. The rental shop charges an initial fee of $12 plus $8 per hour to
rent the boat. If he paid a total of $120 when he rented a boat, for how many hours was the
boat rented?
Answer:
13.5 hr.
Step-by-step explanation:
Let h = no. of hours
Total cost = 12 + 8h = 120
8h = 108
h = 13.5 hr.
Find the area of the triangle using Pythagorean theorem
Answer:
48
Step-by-step explanation:
Remark
Use a^2 + b^2 = c^2 to solve for the height.
Givens
c = 10
b = 6
h = ?
Solution
b^2 + h^2 = c^2
6^2 + h^2 = 10^2
36 + h^2 = 100 Subtract 36
h^2 = 100 - 36
h^2 = 64 Take the square root of both sides
sqrt(h^2) = sqrt(64)
h = 8
The height = 8
Area = 1/2 * b * h
Area = 1/2 *12 * 8
Area = 48

t
Answer:
t = 35.13
Step-by-step explanation:
Simplifying
62.52 = 27.39 + t
Solving
62.52 = 27.39 + t
Solving for variable 't'.
Move all terms containing t to the left, all other terms to the right.
Add '-1t' to each side of the equation.
62.52 + -1t = 27.39 + t + -1t
Combine like terms: t + -1t = 0
62.52 + -1t = 27.39 + 0
62.52 + -1t = 27.39
Add '-62.52' to each side of the equation.
62.52 + -62.52 + -1t = 27.39 + -62.52
Combine like terms: 62.52 + -62.52 = 0.00
0.00 + -1t = 27.39 + -62.52
-1t = 27.39 + -62.52
Combine like terms: 27.39 + -62.52 = -35.13
-1t = -35.13
Divide each side by '-1'.
t = 35.13
Simplifying
t = 35.13

Answer:
4/3
10/3
24/3
...........
Answer:
4/3
10/3
24/3 or 8
Step-by-step explanation:
x = y - 2/3
2 - 2/3 = 2/1 - 2/3 = 6/3 - 2/3 = 4/3
y = x + 2/3
8/3 + 2/3 = 10/3
y = x + 2/3
22/3 + 2/3 = 24/3 = 8
A bear loves visiting his friend, the piglet. The distance between their houses is 300m , and the bear always walks from his house to the piglet's house in exactly the same amount of time. But today, the bear stops at a beehive after walking —1 of the 4 distance. He eats honey for 2.5 minutes and then continues to the piglet's house at a speed 15 m/min faster than usual. The total journey to the piglet's house takes the exact same amount of time as it usually does, when the bear does not stop for honey. How long does the journey take?
Answer:
10mins
Step-by-step explanation:
you can draw a rtd chart for this problem
rate (m/min)| time (mins) | distance (m )
regular: (300/x) | x | 300m
fist 1/4 : (300/x) | 75: (300/x) | 75m
last 3/4: | (300/x)+15 | 225:(300/x + 15) | 225m
then, make an equation for the times:
x= (75: (300/x)) + (225: ( (300/x)+15) + 2.5 = x
// get the 2.5 mins from the stop for honey, and we know that regular speed is equal to the one with a stop
solve equation to get x=-20/3 , x=10, because speed is positive, x=10 is the most reasonable answer

Sue buys a car costing £8000 plus
20% VAT.
She pays £4000 deposit and then
chooses to pay the balance in ten equal
monthly payments.
Calculate each monthly payment
CS
Answer:
Each monthly payment is of £560.
Step-by-step explanation:
Sue buys a car costing £8000 plus 20% VAT?
She has to pay:
8000 plus 20% of tax. So
[tex]T = 8000 + 0.2*8000 = 9600[/tex]
She pays £4000 deposit and then chooses to pay the balance in ten equal monthly payments.
4000 deposit, and then 9600 - 4000 = 5600 divided in ten equal monthly payments.
5600/10 = 560
Each monthly payment is of £560.
