Find the value of the lettered angle b
Answer:
60°Step-by-step explanation:
30 is an opposite angle (2 angles of 30°)
sum of all angles = 360°
360 - 90 -30 - 150 - 30 = 60°
check
60 + 30 + 150 + 30 + 90 = 360°
the answer is good
Answer:
b = 60
Step-by-step explanation:
A straight line is 180 degrees
30+90+b = 180
Combine like terms
120 +b = 180
b =180-120
b = 60
Find the rate of change of the linear function shown in the graph. Then find the initial value.
rate of change is change in y / change in x
(-1 - -3)/ (0 - -6) = 2/6 = 1/3
initial value is the y value when x is 0 , which is -1
2.8 + 32x + 1 =16.6
Answer:
x = 0.4Step-by-step explanation:
Assuming you are looking for x
2.8 + 32x + 1 = 16.6
32x = 16.6 - 2.8 - 1
32x = 12.8
x = 12.8 : 32
x = 0.4
-----------------------
check
2.8 + 32 * 0.4 + 1 = 16.6
2.8 + 12.8 + 1 = 16.6
16.6 = 16.6
the answer is good

If a^2 and b are directly proportional, and a=2 when b=9, then what is b when a=6?
Answer:
b = 81
Step-by-step explanation:
given a² and b are directly proportional then the equation relating them is
a² = kb ← k is the constant of proportionality
to find k use the condition a = 2 when b = 9 , then
2² = 9k
4 = 9k ( divide both sides by 9 )
[tex]\frac{4}{9}[/tex] = k
a² = [tex]\frac{4}{9}[/tex] b ← equation of proportion
when a = 6 , then
6² = [tex]\frac{4}{9}[/tex] b
36 = [tex]\frac{4}{9}[/tex] b ( multiply both sides by 9 to clear the fraction )
324 = 4b ( divide both sides by 4 )
81 = b

oas on a callable bond is 75 basis points using on-the-run treasuries as benchmark rates. which is correct?
When the callable bond is 75 basis points using on-the-run treasuries as benchmark rates,it implies that the nominal speed is 75bp over the treasury benchmark rates.
What is a bond?It should be noted that a callable bond is the debt instrument whee the issuer has the right to return the principal of the investor.
Callable bonds are also known as redeemable bonds and they're paid off before the maturity date of the bond by the issuer.
It gives room for companies to pay off their debt early and then get benefit regarding favorable interests.

find the amount of Carrie's allowance.
Linear equation: 1/4a+1/3a+8=22
Answer:
a=24
Step-by-step explanation:
Start by subtracting 8 from both sides giving:
1/4a+1/3a=14
Then find a common denominator between the two a terms which is 12 giving:
3/12a+4/12a=14
Combine the two terms:
7/12a=14
Then divide by 7/12 giving you a=24

5a. a° = 128°
5b. b° = 1.3°
5c. c° = 341°
How to determine the unknown sides5a
a° = 128°
This is because parallel angles are equal and angles a° and 128° are parallel to each other
5b
Angles (4b-10)° and (2b - 2)° are equal.
This is because alternate angles are equal and they are alternate to each other
To find b , equate both angles
4b - 10 = 2b - 2
collect like terms
4b + 2b = -2 + 10
6b = 8
Make 'b' subject of formula
b = 8/6
b = 1.3°
5c.
c° is at angle at a point.
19° is alternate to the other part of the point
We have, c° + 19° = 360° (angle at a point)
c° + 19° = 360°
Make 'c' subject of formula
c° = 360° - 19°
c° = 341°
Thus, the unknown angles are given as a = 128°, b = 1.3°, c = 341°

First we need to find the hourly rate for Annette
Take the dollars earned and divide by the number of hours
30/2 = 15 dollars per hour
Now we can find the hourly rate for Carla
96/6 =16 dollars per hour
Carla has the higher hourly rate since she earns more per hour

What is an isosceles right angled triangle?An isosceles right angled triangle has two equal sides, and those two equal sides make 90 degrees (right angle) internally.
Since the two of the angles of the triangle are equal, therefore, the length on the opposite sides of this angle will be equal to each other. Hence, we can write that the length of the side s will be equal to 4.
Hence, the correct option is A.
