i think i know the answer?
for the union its [-7,5] and for the intersection its [-3,0]
is that right? thank youuuu
Answer:
Lets name the first set A and the second one B.
The union:
A∪B = {-7,0}∪{-3,5} = {-7, -3, 0, 5}The intersection:
A∩B = {-7,0}∩{-3,5} = ∅ as no common elementsA plane flew at a constant speed between Denver and Chicago.
It took the plane 1.5 hours to fly 915 miles.
How far would the plane fly in t hours at this speed?
Answer:
[tex]406.66t[/tex]
Step-by-step explanation:
1.5 : 915 = 610
610 ÷ 2 = 305
305 ÷ 3 = 101.66
101.66 × 4 = 406.66 mph
Thus, the answer is 406.66 × t

what is 174 dived by 6 and how u solved it
Answer:
Step-by-step explanation:
187 divided by 7 is 6.5
Answer: 29
Step-by-step explanation:
174 = dividend
6 = divisor
The divisor (6) goes into the first digit of the dividend (1), 0 time(s). Therefore, put 0 on top Multiply the divisor by the result in the previous step (6 x 0 = 0) and write that answer below the dividend. Subtract the result in the previous step from the first digit of the dividend (1 - 0 = 1) and write the answer below.
Move down the 2nd digit of the dividend (7) like this:
0
6 ⟌ 1 7 4
- 0
1 7
Multiply the divisor by the result in the previous step (6 x 2 = 12) and write that answer at the bottom:
0 2
6 ⟌ 1 7 4
- 0
1 7
1 2
Subtract the result in the previous step from the number written above it. (17 - 12 = 5) and write the answer at the bottom.
0 2
6 ⟌ 1 7 4
- 0
1 7
- 1 2
5
Move down the last digit of the dividend (4) like this:
0 2
6 ⟌ 1 7 4
- 0
1 7
- 1 2
5 4
Multiply the divisor by the result in the previous step (6 x 9 = 54) and write the answer at the bottom:
0 2 9
6 ⟌ 1 7 4
- 0
1 7
- 1 2
5 4
5 4
Subtract the result in the previous step from the number written above it. (54 - 54 = 0) and write the answer at the bottom.
0 2 9
6 ⟌ 1 7 4
- 0
1 7
- 1 2
5 4
- 5 4
0
You are done, because there are no more digits to move down from the dividend.
The answer is the top number and the remainder is the bottom number.
Therefore, the answer to 174 divided by 6 calculated using Long Division is:
29
0 Remainder

Answer:
equation is y= 50 + 3f
57F
15 Minutes
Step-by-step explanation:
a) the equation above because 50 is the starting temp and every 3 minutes is another degree F
b) if the temp rises 1 degree every 3 minutes, then 21/3 is 7 degrees hotter plus 50, which is 57 F.
c) if 50 plus 3f is the equation, then 3 times 5 will make 55 degrees. After 15 minutes, the temp will be 55 F.

Which of the following best defines qualitative observation?
Question 5 options:
Data that can be observed using our sense of sight only
Data that can be observed with our five senses
Data that must be measured
Data that must be quantified
Answer:
""Data that can be observed with our five senses """is right option..
Step-by-step explanation:
A qualitative observation involves the use of five sensory organs, sight, smell, taste, touch, and hearing, and their function to examine the attributes. Being subjective in nature, it focuses on the characteristics and qualities of the variables rather than the numerical value.
If you are dealt 4 cards from a deck 52 find the probability that 4 cards are clubs
Step-by-step explanation:
There are 13 clubs in the deck of 52 cards. That makes the probability of the first card being a club 13/52, which reduces to 1/4.
For the second card, there are 12 clubs in the 51 that remain, so the probability it's a club is 12/51, or 4/17.
There are now 11 clubs in the remaining 50, so the probability the third card is a club is 11/50.
Finally, you have 10 clubs out of 49 cards, making the probability that the 4th card is a club is 10/49.
To get the probability of this whole scenario, just multiply the four fractions (and simplify).
Answer:
Step-by-step explanation:
P(Clubs) = 13C4 // 52C4
The order doesn't matter in either case.
13 * 12 * 11 * 10
============
52 * 51 * 50 * 49
P(4 cards all clubs) = 11/4165
P(4 cards all clubs) = 0.002641
You buy milk at $2.48 per gallon. One portion of oatmeal requires 4 ounces of milk. How much does the milk for one portion cost? Round to the nearest cent.
The milk costs "7.75" for one portion cost. A further solution is provided in the below section.
The given information in the question is:
Milk per gallon,
= $2.48
We know that,
→ [tex]1 \ gallon = 128 \ ounces[/tex]
then,
→ [tex]128 \ ounces \ cost =[/tex] $[tex]2.48[/tex]
hence,
→ The 4 ounces of milk cost will be:
= [tex]\frac{2.48}{128}\times 4[/tex]
= [tex]\frac{9.92}{128}[/tex]
= [tex]0.0775[/tex]
or,
= [tex]7.75 \ cents[/tex]

i need 23, 28, and 40 desperately
Take the digits 5, 4, 3, 2 and 1, in that order. Using those digits and the four arithmetic signs — plus, minus, times and divided by — you can get 1 with the sequence 5 - 4 + 3 - 2 - 1. You can get 2 with the sequence (5 - 4 + 3 - 2) x 1.
The question is ... how many numbers from 1 to 40 can you get using the digits 5, 4, 3, 2, and 1 in that order along with the four arithmetic signs?
You can group digits with parentheses, as in the example. There are no tricks to this, though. It's a straightforward puzzle. How many numbers from 1 to 40 can you get — and, specifically, what number or numbers can you not get?

Additional comment
I used a computer program to evaluate different sequences of operations. Attached is one result for each integer 1-40 except 39. The notation here is postfix, but is not difficult to translate to infix with parentheses. Starting with the left-most operation (op), the pattern (a, b, op) → (a op b) is used. For example, the listing for 38 is 543+*21++, so this becomes 5*(4+3)+(2+1) = 38.

Answer:
[tex]\displaystyle\frac{100 \hspace{4}inches}{1 \hspace{4}minute}*\frac{1 \hspace{4}foot}{12 \hspace{4}inches}[/tex]
Step-by-step explanation:
Hi there!
100 inches per minute
⇒ [tex]\displaystyle\frac{100 \hspace{4}inches}{1 \hspace{4}minute}[/tex]
To change this into feet per minute, we need to cancel out the "inches" unit and replace it with feet. The "minute" unit stays the same.
To cancel inches out and leave feet remaining, we must multiply [tex]\displaystyle\frac{100 \hspace{4}inches}{1 \hspace{4}minute}[/tex] by a fraction that has inches in the denominator and feet in the numerator:
[tex]\displaystyle\frac{100 \hspace{4}inches}{1 \hspace{4}minute}*\frac{1 \hspace{4}foot}{12 \hspace{4}inches}[/tex]
Notice how inches cancels out:
[tex]\displaystyle\frac{100 \hspace{4}}{1 \hspace{4}minute}*\frac{1 \hspace{4}foot}{12 \hspace{4}}\\\\= \displaystyle \frac{100 \hspace{4} feet }{12 \hspace{4} minutes} \\\\= \displaystyle \frac{25 \hspace{4} feet }{3 \hspace{4} minutes}[/tex]

I need help with this ASAP
Step-by-step explanation:
it's really simple.
g(f(x)) means that you use x to create f(x), and then you use this f(x) as argument in g(x).
with our functions here it means in general to use f(x) = 4 - x as argument (instead of purely x) in g(x).
g(f(x)) = 5×(4 - x) - 2 = 20 - 5x - 2 = 18 - 5x
that is the whole trick.
now, when we have a specific x value (x = 6 in our example here), it can be even simpler.
we need to "feed" 6 into f(x).
4 - x = 4 - 6 = -2
so, f(6) = -2
now this -2 becomes the argument for g(x).
5×(-2) - 2 = -10 - 2 = -12
so, g(f(6)) = -12
let's check for control and also use the functional definition of g(f(x)) we established above :
18 - 5×6 = 18 - 30 = -12
the same result, so all correct.

The total cost of a jacket and a pair of pants was $66.12. If the price of the jacket was $3.26 less than the pair of pants, what was the price of the jacket? Express your answer as a simplified fraction or a decimal rounded to two places.
Answer:
The price of the jacket was $31.43
Step-by-step explanation:
Let the cost of a jacket = x
Let the cost of a pair of pants = y
Such that,
x + y = $66.12.........Equation 1.
From the conditional statement,
x = y - $3.26..........Equation 2.
Solve both equations simultaneously, using the substitution method
From Equation 2;
x = y - 3.26
Substitute y - 3.26 for x in Equation 1.
x + y = 66.12, now becomes,
y - 3.26 + y = 66.12
collect like terms
y + y = 66.12 + 3.26
2y = 69.36
y= 69.36/2 = $34.69.
Put y = $34.69 in Equation 2. to obtain x
x = 34.69 - 3.26
x = $31.43

All the elements of the given set {2,4,8,...,256} are - {2, 4, 8, 16, 32,64, 128, 256} that are total 8 in numbers.
The set is formed by the number of objects in a particular manner, these objects are called elements of the set. The elements of the set are written inside a curly bracket separated by a comma in a particular or specific order.
There are two methods to represent the set and its elements that are:
Set notation: define the elements and properties of sets using symbols that help in describing the relationship between elements in the set.in this case, {[tex]2^{1},2^{2},2^{3},2^{4},2^{5},2^{6},2^{7},2^8[/tex]} as we know,
so the set notation would be :
= {x:x = [tex]2^{n}[/tex], n∈N and 1 ≤ n ≤ 8}
listing method: simple method that include the members or elements of the set are written as a list, separated by the comma and enclosed within the curly braces.The listing method: {2, 4, 8, 16, 32,64, 128, 256}\

Which best represents the commutative property of addition
A. 15+ (-15) = 0
B. (15+11) + 4 = 15 + (11+4)
C. 15+0=15
D. 15+11=11+15
Answer:
B
Step-by-step explanation:
the answer is (15+11)+4=15+(11+4)
The expression (15+11) + 4 = 15 + (11+4) best represents the commutative property of addition. The correct option is B.
What is cumulative property?The cumulative property states that if the position of the numbers when they are in addition is changed then it will not affect the final result of the addition. If altering the operands' order has no effect on the outcome, the binary operation is commutative in mathematics.
The commutative property basically states that x+y can be flipped yet have the same meaning so x+y = y+x ~.
In the option B the expression (15+11) + 4 = 15 + (11+4) representing the cumulative property. On changing the summation terms the final answer will not change.
Therefore, the expression (15+11) + 4 = 15 + (11+4) best represents the commutative property of addition. The correct option is B.

Step-by-step explanation:
3(y+13 )=36
y+13=12
y=-1
(1/2) x -1 = -1/2
3(y + 13) = 36
Distribute the 3
3y + 39 = 36
Subtract 39 from both sides.
3y = -3
Divide both sides by 3
y = -1
1/2y = 1/2(-1) = -1/2
