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

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
Hope this helps

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°

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
Choose the question that has only one possible answer.
A. How tall are you?
B. What are the lengths of the lizards in your backyard?
C. What are the heights of the people in your class
Answer:
A. How tall are you?
Step-by-step explanation:
The response given to a questions will usually depend on the type of question asked. We have the open ended and the close ended. depending on whether the question can be answered by a yes or no alternative.
The question how tall are you? Simply requires a phrase answer with the height of the person being asked. Such as 6 feets, 12 feets, etc.
The question, length of lizards in backyard and the height of students in class requires a range of values to express the height of the lizards and students.
Wendell jumps off a cliff into the water below. His jump can be represented by the equation h + -4 (4t +5) (t-3) Where H is the height in feet above the water and t is the time in seconds. How many seconds will it take Wendell to reach water?

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
