If < A and < B form a linear pair, and m< A = x - 21 degrees, and m< B = x + 15 degrees, then find x.
The value of x = 93 degree and value of angle A and B is 72 , 108 degree
What is a Linear Pair ?The pair of triangles that are supplementary and they add to form 180 degree angle are called Linear Pairs.
It is given that
∠ A = x -21
∠ B = x+15
also it is given that
angle A and B form a linear pair
∠ A + ∠ B = 180 degree
To find the value of x
x -21 + x+15 = 180
2x - 6 = 180
2x = 186
x = 93 degree
so
∠ A = x -21 = 93 -21 = 72 degree
∠ B = x+15 = 93+21 = 108 degree
Therefore the value of x = 93 degree and value of angle A and B is 72 , 108 degree.

Find y. right triangles
Answer:
√2
Step-by-step explanation:
Angle ( θ ) = 45
Hypotenuse side = 2
Opposite side = x
Formula : -
sin θ = Opposite side / Hypotenuse side
Note :
The value of sin 45 = 1/√2
sin 45 = x/2
1/√2 = x/2
Cross multiply,
x*√2 = 2*1
x√2 = 2
2 can be simplified as √2 * √2
x√2 = √2*√2
Divide √2 on both sides,
x = √2
Solve the following problem using linear systems: You have a bottle of a 2% solution of iodine and a bottle of a 66% solution of iodine. You need 16 liters of a 47% solution. How many liters of the 2% and 66% solutions should you mix together?
The quantity of liters of the 2% and 66% solutions should you mix together is 4.75 and 11.25 liters.
let
x = liters of 2% solutiony = liters of 66% solutionx + y = 16
0.02x + 0.66y = 0.47 × 16
from (1)
x = 16 - y
Substitute into (2)
0.02x + 0.66y = 0.47 × 16
0.02(16 - y) + 0.66y = 7.52
0.32 - 0.02y + 0.66y = 7.52
- 0.02y + 0.66y = 7.52 - 0.32
0.64y = 7.20
y = 7.20/0.64
y = 11.25 liters
Substitute y = 11.25 liters into (1)
x + y = 16
x + 11.25 = 16
x = 16 - 11.25
x = 4.75 liters

Answer:
I think you would have to do 2 times 7
Answer:
h = 2.5cm or 5/2 cm
Step-by-step explanation:
Vol = Basearea•h
In your question, the base is the triangle shape. The rectangles go around the sides of the 3-d shape and on top is another triangle that we can't really see. In your image it is kind of laying on its side. So if we stand it up properly, the triangles are on the top and bottom. The triangle is the base.
Volume was given; it is 35. Also given is one side of the rectangles, that is 7.
So we can fill in 35 and 7 into the volume formula and calculate the Basearea.
V = B • h
35 = B • 7
35 = 7B
Divide by 7.
5 = B.
We have calculated the Basearea. This is the area of the triangle shaped bottom. The area formula for a triangle is:
A = 1/2bh
We just found that A=5 and we were given that the base of the triangle is 4.
A = 1/2bh
5 = 1/2•4•h
5 = 2h
Divide by 2.
5/2 = h
This is the height of the triangle, h in the picture. (The h in the volume formula and h in the triangle are different)
This is what the question is asking for, h = 5/2 or in decimals, h = 2.5cm
Determine the equation of the altitude from A.
Answer:
y = - 3x + 11
Step-by-step explanation:
the altitude is a line from the vertex A drawn perpendicular to the opposite side BC
calculate the slope of BC using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = B (- 7, 3 ) and (x₂, y₂ ) = C (- 1, 5 )
[tex]m_{BC}[/tex] = [tex]\frac{5-3}{-1-(-7)}[/tex] = [tex]\frac{2}{-1+7}[/tex] = [tex]\frac{2}{6}[/tex] = [tex]\frac{1}{3}[/tex]
given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{3} }[/tex] = - 3
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept ) , then
y = - 3x + c ← is the partial equation
to find c substitute A (4, - 1 ) into the partial equation
- 1 = - 12 + c ⇒ c = - 1 + 12 = 11
y = - 3x + 11 ← equation of altitude from A

(1 point) 7 months 58 months 84 months 700 months
The correct answer is 700 months .
What is simple interest?Simple interest is based on the principal amount of a loan or the first deposit in a savings account. Simple interest doesn't compound, which means a creditor will only pay interest on the principal amount and a borrower would never have to pay more interest on the previously accumulated interest.Given,
I = 105
P = 100
r = 0.15
Now use simple interest formula,
[tex]S.I. = \frac{p * r* t}{100}[/tex]
105=100×(0.15)×(t)
Swap sides so t is on the left.
100 ×(0.15)×(t)=105
Divide both sides by 100.
0.15t=1.05
Divide both sides by 0.15
t=700
So, we see that it takes 700 months to earn this amount.

A store sells both cold and hot beverages. Cold beverages, c, cost $1.50, while hot beverages, h, cost $2.00. On Saturday, drink receipts totaled $360, and 4 times as many cold beverages were sold as hot beverages.
Which system of linear equations represents the beverage sales on Saturday?
c = 4 times h
Linear equation: 1.5c + 2h = 360
Hello!
Your answer should be..
c=4h ( as there are 4 hours )
1.5c+2h=360
c is 1.50 and h is 2.00 so you must add them to reach 360

Step-by-step explanation:
So when an equation has and odd degree, it will go in the opposite direction on both ends, so if y went towards infinity as x went towards infinity, then y would go towards negative infinity as x goes towards negative infinity. In this case, by looking at the graph it has an odd degree, due to opposite end behaviors, although on both ends it's increasing because even though it appears that it's going down on the left side, that's only if you start from the right and go towards the left. So it's really increasing from negative infinity to -1, and then it decreases from -1 to 2, until it once again starts increasing from 2 to infinity. This can be represented as (-infinity, -1) U (2, infinity) for increasing and (-1, 2) as decreasing
