Answer:
a = 7
b =?
c = 1/2
a + by = 0
7 + b × 1/2 = 0
7 + 1/2 b = 0
1/2 b = - 7
b = -7 × 2
b = - 14
a + by
= 7 + - 14 × 1/2
= 7 -14/2
= 7 - 7
= 0
Step-by-step explanation:
Id.k if you forgot to write the value of b or not, since the value of b is not given, this will be ur answer.
there are two pans of lasagna at a school dinner. parents were careful to cut each pan of lasagna into equal portions. Tanya had 2 portions in one pan, while Daniel took 4 portions from the other pan. They both took the same amount of lasagna. he is this possible?
1. show how the lasagna was divided into portions so Tanya's 2 portion are equal to Daniel
2a. what fraction did Tanya eat?
1b. what fraction did Daniel eat.
2.how do you know these fractions are equivalent?
Answer:
1. Tanya ate 2/3 of the lasagna and Daniel ate 4/6 of the lasagna.
2a. 2/3
1b. 4/6
2. 2/3 is the same thing as 4/6, 2/3 x 2/2=4/6, 4/6÷2/2=2/3

The angle measures of a triangle are shown in the
diagram
60
What is the value of x?
Is B 30 right?
b is the correct answer u got it
Answer:
C. 30
Step-by-step explanation:
2x = 60
x = 30
Also because the right angle of a triangle which is the angle where (2x) is at is equal to 90 degrees always, so since one of the angles is 60 the other will be 30 because the three angles of a triangle add up to 180 degrees:
90 + 60 = 150
180 - 150 = 30
Evaluate the function requested. Write your answer as a fraction in lowest terms.

Find cos B.
Answer:
[tex]\cos B=\dfrac{9}{41}[/tex]
Step-by-step explanation:
Given that,
Hypotenuse = 82 units
Base = 80 units
Height = 18 units
We need to find the value of cos B.
We know that,
[tex]\cos\theta=\dfrac{Base}{Hypotenuse}[/tex]
For angle B, Hypotenuse = 82 units, Height = 80 units and base = 18 units
[tex]\cos B=\dfrac{18}{82}\\\\\cos B=\dfrac{9}{41}[/tex]
Hence, the correct option is (A).

What is the perimeter of the figure?"
9514 1404 393
Answer:
46 yd
Step-by-step explanation:
The sum of horizontal lengths across the top is 8+6 = 14 yd. The length across the bottom is the same, so the total of horizontal lengths is
14 yd +14 yd = 28 yd
The sum of vertical lengths at the right is the same as the sum of vertical lengths at the left, 9 yd, so the total of vertical lengths is ...
9 yd + 9 yd = 18 yd
The total of all lengths around the perimeter of the figure is ...
28 yd + 18 yd = 46 yd

9514 1404 393
Answer:
x = {2π/3, 4π/3}
Step-by-step explanation:
The equation can be factored as ...
(cos(x) +3)(2cos(x) +1) = 0
The solutions are the values of x where the factors are zero.
cos(x) +3 = 0
cos(x) = -3 . . . . . . no real solution
__
2cos(x) +1 = 0
cos(x) = -1/2
x = arccos(-1/2) = 2π/3
The other solution in the desired interval is ...
x = 2π -(2π/3) = 4π/3
The solutions are x∈ {2π/3, 4π/3}.

Find the are of the composite shape.
mm?
Answer:
18 feet²
Step-by-step explanation:
A composite figure is made up of simple geometric shapes. To find the area of a composite figure or another irregular-shaped figure, divide it into simple, nonoverlapping figures. Find the area of each simpler figure, and then add the areas together to find the total area of the composite figure.
Finding the Area of Composite Shapes
In order to find the composite area of two or more shapes, simply find the area of each shape and add them together. Therefore, the answer is 96 feet²

A copy machine makes 136 copies in 4 minutes and 15 seconds. How many copies does it make per minute?
Answer:
The copy machine makes 32 copies per minute.
Step-by-step explanation:
Given that a copy machine makes 136 copies in 4 minutes and 15 seconds, to determine how many copies does it make per minute, the following calculation must be performed:
15 seconds = 0.25 minutes
136 / 4.25 = X
32 = X
Therefore, the copy machine makes 32 copies per minute.
find the absolute maximum absolute minimum of the function F(x)=(x^2-12x+32)^(1/3) on the interval [3,10]
9514 1404 393
Answer:
minimum: -∛4 ≈ -1.58740maximum: ∛12 ≈ 2.28943Step-by-step explanation:
The expression under the radical can be written in vertex form as ...
x^2 -12x +32 = (x -6)^2 -4
The function will be symmetrical about x=6. The minimum is at x=6 where we have ...
F(6) = ∛(-4)
The maximum is at the end of the interval farthest from the vertex, so is ...
F(10) = ∛((10 -6)² -4) = ∛12
The minimum is -∛4 ≈ -1.587; the maximum is ∛12 ≈ 2.289.
