Answer:
A) 0
B) 9
Step-by-step explanation:
A) −10 − 13 − 17 − (−40) [B.E.D.M.A.S rule] (First bracket)
= - 10 - 13 - 17 + 40
= 40 - 10 - 13 - 17. (Then subtraction)
= 40 - 40
= 0 (Ans)
B) 111 − (31 + 78) − 7 + 14 [B.E.D.M.A.S rule] (First bracket)
= 111 − 109 − 7 + 14. (Then addition)
= 111 + 14 - 109 - 7
= 125 - 116. (At last subtraction)
= 9 (Ans)

A triangle has two angles that have measures of 92° and 31°. What is the measure of the third angle of the triangle?
A 23
B 57
C 43
C 33
Answer:
57⁰
Step-by-step explanation:
A triangle measures 180⁰, so to find the answer to these questions you just have to add the degrees you know
92⁰+31⁰=123⁰
after you take 180⁰ and subtract the degrees you know your triangle has
180⁰-123⁰= 57⁰
Answer:
57°
Step-by-step explanation:
so triangle angles all add up to 180 so its a matter of subtraction
[tex]92 + 31 + x = 180[/tex]
x is the 3rd angle we need to find
[tex]92 + 31 + x = 180\\\\92 + 31 = 123\\\\180 - 123 = 57\\[/tex]
so the missing 3rd angle is 57°

Solve for h. You are working to save money for a video game console. You need to save $500. You already have $200 saved. You work at GameStop and make $12 an hour. Write and solve an equation to represent how many hours (h) you need to work to make the rest of the money.
Answer:
25 more hours
Step-by-step explanation:
First you need to make an equation
200+12x=500
Then you solve it by:
Subtracting 200 from both sides
12x=300
Then divide both sides by 12
x=25
Then you can check your answer by plugging in the number
200+12x25=500

Which expression is NOT equivalent to −6×(13+13)? −63+13 −6×23 −6×(2×13) (13+13)×(−6)
Answer:
I know that -63+13= -50
(-6) * 23 = (-138) are NOT equivalent, the only expressions that are equivalent are (13+13)x(-6) and -6x(2x13) they both equal to -156 which is to say -6x(13+13) Are the same

Select all the correct answers. Annie transforms the graph of y = 2x into the graph of y= 2x - 4. Which statements correctly describe this transformation?
Answer- Plato; It is the graph of y=2x translated 4 units downward. & It is the graph of y=2x translated 2 units to the right.
Answer:
It is the graph of y=2x translated 4 units downward
Step-by-step explanation:
Given
[tex]y = 2x[/tex] to [tex]y' = 2x - 4[/tex]
Required
We have:
[tex]y = 2x[/tex]
Subtract 4 from both sides [In other words, shift downward by 4 units]
[tex]y - 4 = 2x - 4[/tex]
This implies that:
[tex]y' = y -4[/tex]
Substitute [tex]y = 2x[/tex]
[tex]y' = 2x -4[/tex]
Answer:
It is the graph of y = 2x translated 4 units downward.
It is the graph of y = 2x translated 2 units to the right.
Step-by-step explanation:
Recall that f(x) − k is a vertical translation that translates f(x) down k units. And, a vertical translation also translates a function horizontally, and vice versa. So, y = 2x − 4 translates the function y = 2x down 4 units. But 2x − 4 is also equal to 2(x − 2), so y = 2x − 4 also describes a translation to the right by 2 units.

The graph of a twice differential function is shown at right. Which of the following is true?
Answer:
(C)
Step-by-step explanation:
looking from the slope: f'(2) is negative
f(2)=0
the curve concave upward: f''(2) is positive
f'(2)<0
f(2)=0
0<f''(2)
f'(2)<0<f''(2)
The expression which is true n the graph of a twice differential function is f' (2) < 0 < f'' (2) so, option C is correct.
What is a differential function?A function that has a derivative at each point in its domain is referred to as a differentiable function of one real variable in mathematics. In other words, each interior point in the domain of a differentiable function's graph has a non-vertical tangent line.
Given:
The coordinate of the graph is shown in figure (2, 0),
As we can see from the graph, the slope: f' (2) is negative (Downwards)
Again, from the graph
f(2) = 0
Thus, the curve concave upward: f'' (2) is positive (upward)
f' (2)<0
f (2)=0
0 < f'' (2)
f' (2) < 0 < f'' (2)
Therefore, f' (2) < 0 < f'' (2) is true in the given graph.

Assume that 5 people, including the husband and wife pair, apply for 4 sales positions. People are hired at random.
(1) What is the probability that both the husband and wife are hired?
(2) What is the probability that one is hired and one is not?
Answer:
a) 0.2 = 20% probability that both the husband and wife are hired
b) 0.4 = 40% probability that one is hired and one is not
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The order in which the people are chosen is not important, which 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]
(1) What is the probability that both the husband and wife are hired?
Desired outcomes:
Both selected, only one possible outcome, so [tex]D = 1[/tex]
Total outcomes:
4 from a set of 5. So
[tex]T = C_{5,4} = \frac{5!}{4!1!} = 5[/tex]
Probability:
[tex]p = \frac{D}{T} = \frac{1}{5} = 0.2[/tex]
0.2 = 20% probability that both the husband and wife are hired
(2) What is the probability that one is hired and one is not?
Desired outcomes:
One selected, one not, so two possible outcomes(Wife yes, husband not, or husband yes and wife not). So [tex]D = 2[/tex]
Total outcomes:
4 from a set of 5. So
[tex]T = C_{5,4} = \frac{5!}{4!1!} = 5[/tex]
Probability:
[tex]p = \frac{D}{T} = \frac{2}{5} = 0.4[/tex]
0.4 = 40% probability that one is hired and one is not
Shanti is taking a cube-shaped gift to a friend's birthday party. She wants to wrap it but she doesn't have very much paper, so she does not overlap any of the edges.
How much paper did it take to cover the gift?
Answer:
1014 cm²
Step-by-step explanation:
We are to find the surface area of the cube
The formula for the surface area of a cube is given as
A = 6a²
Where a = side length
From the above diagram, side length = 13cm
The surface area = 6 × 13²
= 1014 cm²
Therefore, it would take 1014 cm² of paper to cover the gift

A room is 8m long ,6m wide and 3.5m high. Find the cost of white washing its four walls at the rate of 50 per square meter.
Answer: 4900
Step-by-step explanation:
Length = 8m.
Width = 6m
Height = 3.5m
Area of the walls will be:
= 2(l × h) + 2(w × h)
= 2(8 × 3.5) + 2(6 × 3.5)
= 2(28) + 2(21)
= 56 + 42.
= 98m²
Since the rate is given as 50 per square meter, the cost of whitewashing its four walls will be:
= 50 × 98.
= 4900
