Write an equivalent expression to 2 + 3 + 5 + 6 by combining like terms.
Answer:
answers are below
Step-by-step explanation:
(2+3) + (5+6)
(5) + (11)
equivalent expression: 5 + 11
is this the actual expression though? because in this case, i think that your expression should 2x + 3 + 5x + 6 and not what you mentioned.
however, if that is the case then your answer would be:
7x + 9
Law of Sines Round to the nearest degree.
Answer:
Step-by-step explanation:
recall law of Sines Sin(A) /a = Sin(B) / b
for this question
F = A = 105 and a = 37
E = B and b = 28
then plug those into our law of Sines equations
Sin(105) / 37 = Sin(B) / 28
0.025846 = Sin(B) / 28
28 * 0.025846 = Sin(B)
0.72369 = Sin(B)
arcSin(0.72369) = arcSin ( Sin ( B ) )
46.3599 = B
E = 46° ( rounded to the nearest degree)
Calculate the unit rate.
322 meters in 28 seconds
On one island there lived two friends, Ana and Banana. One of them always tells the truth, while the other always lies. When asked which one is the liar among them, they said: Ana: "Banana ate ten apples yesterday, and he is telling the truth." Banana: "No, I ate five apples yesterday, and Ana is lying." How many apples did Banana eat yesterday?
Answer:
Number of apples ate = 5
Step-by-step explanation:
Fact:
One of them always tells the truth, while the other always lies.
To find how many apples banana ate, we have to figure out who is lying between Ana and Banana.
Ana: "Banana ate ten apples yesterday, and he is telling the truth."
If Ana is telling the truth, that means Banana is also telling the truth because of the statement (... and he is telling the truth).
This is not possible as one of them must be lying. The only option left is that Ana is lying.
Since Ana is lying, it means banana is telling the truth.
Banana: "No, I ate five apples yesterday, and Ana is lying."
Number of apples ate = 5
A zoo has an equal number of African elephants and Asian elephants. The African elephants cost £11 per day to feed and the Asian elephants cost £9 per day to feed. The total daily bill for feeding all of the zoo's elephants is £1000. How many elephants does the zoo have?
Answer:
The zoo has 50 African elephants and 50 Asian elephants which means that there are 100 elephants.
Step-by-step explanation:
From the information provided, you can say that the result of adding up the African elephants cost to feed per day for the number of African elephants plus the Asian elephants cost to feed per day for the number of Asian elephants would be equal to £1000, which can be expressed as:
11x+9y=1000, where:
x is the number of African elephants
y is the number of Asian elephants
Now, as the statement indicates that the zoo has an equal number of African elephants and Asian elephants, this means that x=y and you can replace y with x and solve for x:
11x+9x=1000
20x=1000
x=1000/20
x=50
According to this and considering that the zoo has an equal number of African elephants and Asian elephants, the answer is that the zoo has 50 African elephants and 50 Asian elephants which means that there are 100 elephants.

Find the slope of the line that passes through the pair of points (6,-2) and (5,-4).
Show all work necessary and write your final answer in the box.
Answer:
slope = -10/7Step-by-step explanation:
co-ordinates = (6,-2) (5,-4)
slope = (y² - y¹) / (x² - x¹)
slope = (-4 - 6) / (5 - (-2))
slope = (-10) / (5+2)
slope = (-10) / 7
slope = -10 / 7
Answer:
10/7
Step-by-step explanation:
After Dan makes a basket, Josephine claims she can find the amount of time the ball was in the air (from the time it leave's Dan's hand to the time it enters the basket),
Josephine says she can do this by using Dan's equation (1) = -1649 +18 + 8) and setting the equation equal to zero. Dan doesn't think Josephine's thinking is correct.
Who do you agree with?
Explain your reasoning using mathematical evidence.
Answer:
Step-by-step explanation:
The function is to blurry to see but you would not set the height function equal to zero. Instead h should be set to the height of the basket. The time elapsed would be the second time the ball was at the height of the basket. If I guess what the function is as
-16t^2+18t+8=10
-16t^2+18t-2=0
-16t^2+16t+2t-2=0
-16t(t-1)+2(t-1)=0
(-16t+2)(t-1)=0
So the ball is at 10ft at 0.125s and 1s. So it enters the hoop after 1 second. Of course this is dependent on if I guessed at the correct equation from the picture.

A truck transports 20 boxes of different masses.
Some boxes (C1) weigh 28 kg each , others (C2)
weigh 16 kg each.
Knowing that the total mass of the boxes is
416 kg , how many boxes of each category are
there?
supose there are only c1
20*28 =560
560-416=144
28-16=12
144/12=12(c2)
20-12=8(c1)

In the past month, Lashonda rented 7 video games and 1 DVD. The rental price for each video game was $2.90The rental price for the DVD was $3.50. What is the total amount that Lashonda spent on video game and DVD rentals in the past month
Answer:
Lashonda spent $23.8 all together.
Step-by-step explanation:
We solve this by multiplying how many videogames she bought with how much they cost plus how much that one DVD cost.
7 x 2.90 + 3.50
This equals
23.8
what is the effect on the graph of the function f(x)=x^2 when f(x) is changed to f(x)+9
Given:
The function is
[tex]f(x)=x^2[/tex]
This function is changed to f(x)+9.
To find:
The effect on the graph of the function.
Solution:
The translation is defined as
[tex]g(x)=f(x)+b[/tex] .... (1)
Where, b is vertical shift. If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.
The new function is
[tex]g(x)=f(x)+9[/tex] ...(2)
From (1) and (2), we get
[tex]b=9[/tex]
So, the graph of f(x) shifts 9 units up as shown in the below graph.

Step-by-step explanation:
sorry if Mali.
Answer:
5 miles per hour
Step-by-step explanation:
I made 1/20 to 3 min
1/4 to a mile so x4 both 1/4 and 3 = 12
thats 1 mile per 12 min
60 min divided by 12 equals 5 miles per hour

Ive been working in this for 4 hours please help I don’t understand it at all. I WILL GUVE BRAINLIEST* turned in today would be a life saver.
Answer:
273.25 feet2
Step-by-step explanation:
Daniela can only place the grass in the shaded areas and not the white areas so you want to start by finding the area of the full circle (12.5ft*25ft) and then subtracting the two equal quarter circles on the left and right corners, this can be done by using the radius given (5ft) and finding the area of what the full circle would have been 3.14*(5^2) which is equal too 78.5 (I got 3.14 from pi) and then dividing 78.5 by 4 to find the area of the quarter circle which is 19.625. since there are two quarter circles you multiply 19.625 by 2 and finally subtract your original recttangul by the two quarter circles 312.5(original rectangul)-39.25(the two quarter circles) giving you 273.25 feet2. hope that makes sense
is it A, B, C or D? (30 points)
Answer:
B because you’re reflecting it on the x axis.
