Answer:
19/24 = 0.791666667
Step-by-step explanation:
7/8 - 1/12
Least common multiple of 8 and 12 is 24. Convert 7/8 and 1/12 to fractions with denominator 24.
21/24 - 2/24
Since 21/24 and 2/24 have the same denominator, subtract them by subtracting their numerators.
21 - 2 / 24
Subtract 2 from 21 to get 19.
19/24
A side of the triangle below has been extended to form an exterior angle of 128° . Find the value of x.
Answer:
Step-by-step explanation:

128+x=180
x=52
Answer:
x=52 degrees
Step-by-step explanation:
x=180-128=52 degrees because x is supplementary to 128 degrees.

what equation can be formed to determine the two numbers.
Answer:
If one is given a quadratic equation in the form x2 + bx + c = 0, the sought factorization has the form (x + q)(x + s), and one has to find two numbers q and s that add up to b and whose product is c (this is sometimes called "Vieta's rule" and is related to Vieta's formulas).

Answer:
15 units
Step-by-step explanation:
split the figure into two figures
one with 4x3 and the other with 1x3
then find the area for each and add the areas to get total area
4x3=12
1x3=3
12+3=15
hope this helps have a blessed day :)
Answer:
The answer has to be 168
Step-by-step explanation:
To find the Area you need to multiply all the lengths of each side together.
So 3x4x2x7=168

In trapezoid MNPQ shown below, MN || QP, m&M = 108°, m&P = 4x - 5, and
mxQ = 3x + 21. What is the number of degrees in m«N.
Answer:
Answer:
The answer is below
Step-by-step explanation:
A trapezoid is a quadrilateral (has four sides and four angles) with a pair of opposite parallel sides. The pair of opposite parallel side is known as the base. Also, the angles on the same leg of a trapezoid (adjacent angles) are supplementary (add up to 180°).
In trapezoid MNPQ:
∠M + ∠Q = 180° (angles on the same leg are supplementary)
108 + (3x + 21) = 180
3x + 129 = 180
3x = 51
x = 17
Also:
∠N + ∠P = 180° (angles on the same leg are supplementary)
∠N + (4x - 15) = 180
∠N = 180 - (4x - 15)
∠N = 180 - 4x + 15
∠N = 195 - 4x
substitute x = 17°:
∠N = 195 - 4(17)
∠N = 127°
Which expressions are equivalent to 4/5×15: 5x3, 4x 5/15, 4x3, 3x 15/5, 4x 15/5.

What is the BODMAS rule?According to the BODMAS rule, the brackets have to be solved first followed by powers or roots (i.e. of), then Division, Multiplication, Addition, and at the end Subtraction. Solving any expression is considered correct only if the BODMAS rule or the PEMDAS rule is followed to solve it.
Given here the expression 4/5×15 thus simplifying it we get
4/5×15= 4×3
= 12
Hence, The expression equivalent to 4/5 × 15 is 4×3

Each side of a cube is 4 inches long. What surface area of the cube
Answer:
96 in^2
Step-by-step explanation:
This is because u have to multiply the two bases and the lateral sides to get your area
Answer:
96
Step-by-step explanation:
Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces.
Area = l x w
4 x 4 = 16
16 x 6 = 96

In how many ways can a quality-control engineer select a sample of3 transistors for testing frm a batch of 100 transistors?
Answer:
161700 ways.
Step-by-step explanation:
The order in which the transistors are chosen is not important. This means that we use the combinations formula to solve this question.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
In this question:
3 transistors from a set of 100. So
[tex]C_{100,3} = \frac{100!}{3!(100-3)!} = 161700[/tex]
So 161700 ways.
