Answer:
[tex]b = 6[/tex]
Step-by-step explanation:
Given
[tex]0<b\le 90[/tex]
[tex]\cos(11b + 2) = \sin(12b - 4)[/tex]
Required
Find b
To solve this, we make use of the following trigonometry rule:
If [tex]\cos(\alpha) = \sin(\beta)[/tex]
Then: [tex]\alpha + \beta = 90[/tex]
So:
[tex]11b + 2 = 12b - 4[/tex]
Collect like terms
[tex]11b - 12b = - 4 - 2[/tex]
[tex]-b = - 6[/tex]
Multiply both sides by -1
[tex]b = 6[/tex]

On Monday, a local hamburger shop sold a combined total of 352 hamburgers and cheeseburgers. The number of cheeseburgers
sold was three times the number of hamburgers sold. How many hamburgers were sold on Monday?
To answer this question, you could use algebra.
If the number of cheeseburgers was three times the number of hamburgers, we could write this as.
Cheeseburgers= 3x and Hamburgers = x
We can then write an expression for the total number of burgers.
4x = 352
Divide both sides by four.
x = 88
Because hamburgers = x in relation to the cheeseburgers, that would mean the number of hamburgers sold on monday was 88.

it it a acute, obtuse, or Right someone plzzzz help me
Answer:
Acute angle
Step-by-step explanation:
Obtuse are a bit slanted Right angles are Shaped like an L
Answer:
Obtuse
Step-by-step explanation:
This is an obtuse triangle. Because the degrees of the angle is more than 90 degrees. A right triangle's degrees is 90 exactly and usually has a square marking the angle, an acute is less than 90 degrees for the angle.

y= -x +3 and y = x - 1
Answer:
x=2 and y=1
Step-by-step explanation:
Rewrite equations:
y=−x+3;y=x−1
Step: Solve
y=−x+3
Step: Substitute−x+3foryiny=x−1:
y=x−1
−x+3=x−1
−x+3+−x=x−1+−x(Add -x to both sides)
−2x+3=−1
−2x+3+−3=−1+−3(Add -3 to both sides)
−2x=−4−2x−2=−4−2
(Divide both sides by -2)
x=2
Step: Substitute2forxiny=−x+3:
y=−x+3
y=−2+3
y=1(Simplify both sides of the equation)
Hope this Helps you :)

through: (1, 2), parallel to y = 3x + 1
Answer:
Step-by-step explanation:
so just use the slope of the equations m = 3 and plug in your points
to the point-slope formula
y-2=3(x-1)
y = 3x-3+2
y = 3x -1
now you have an equation that gives you a parallel line to the first, but moved down by 2 :)
Help I’ll give brainliest
Answer:
30 minutes
Step-by-step explanation:
The hare and tortoise meet in 30 minutes at 240 feet.
Answer:
30minutes
Step-by-step explanation:
Tortoise = Hare
2m + 180 = 8m
collect like terms
180 = 8m - 2m
180 = 6m
divide both sides by 6
m = 180/6
m = 30
It will take 30 minutes for the tortoise and hare to meet.
Given f (x) = 1.5x-7, what value of x makes f (x) = 5?
Answer:
f(5) = 0.5
Step-by-step explanation:
f (5) = 1.5(5) - 7
f (5) = 7.5 - 7
f(5) = 0.5

Answer:
B
Step-by-step explanation:
ordered pairs are (x,y) meaning the first value in the ordered pair would be the value you find on the x axis (horizontal) and the second value in the ordered pair would be the value you find on the y axis (vertical).
Find the value of x in 2x – 13 = 5
Answer:
x=9
Step-by-step explanation:
So first, you have to add 13 to both sides to isolate the x so that will make the equation 2x=5+13. Add 5 and 13 to get 18. The equation will now be 2x=18. Divide both sides by 2 because we want x to equal one. This will make it x=18/2. Simplify that and get x=9
Hope this helps
Question
Find the value of x in 2x – 13 = 5 .
ANSWER
Generally, the algebraic expression should be any one of the forms such as addition, subtraction, multiplication, and division. To find the value of x, bring the variable to the left side and bring all the remaining values to the right side. Simplify the values to find the result.
Hence, this information ( x = 9 )

Step-by-step explanation:
Answer:
the answer would be 45 degrees
Step-by-step explanation:
this is because when you look at the rectangle all for interior angles ar e90 degrees each and the line cuts perfectly from one side to the other forming two right triangles. in a right triangle the two acute angles equal 45 degrees each.
Ken is going to throw a biased dice once.
The probability that the dice will land on six is 0.3
(b) What is the probability that the dice will not land on six?
Answer:
0.7
Step-by-step explanation:
Given a biased dice :
Probability of landing on 6 = P(6) ;
P(6) = 0.3
Recall :
P(A') = 1 - P(A)
Therefore,
If
P(6) = 0.3
P(not landing on 6) ; P(not 6) ;
P(not 6) = 1 - P(6)
P(not 6) = 1 - 0.3 = 0.7
Hence, Probability of not landing on 6 = 0.7
