Answer:
By a quick online search, i found two tape diagrams:
13) You: -
Friend: - -
So you have one block, and your friend has two.
We know that you work for 3 hours, this means that your only block must represent 3 hours.
And all the blocks represent the same amount of time, then each one of the two blocks of your friend also represents 3 hours.
Then in total, he tutored for 3 hours + 3 hours = 6 hours.
14) You: -
Friend: - - - - -
In this case, you still have only one block, but now your friend has 5.
Using the same reasoning as above, we can conclude that each block represents 3 hours, and your friend has 5 of them, this means that he tutored for:
5*3 hours = 15 hours

What is the next term of the arithmetic sequence? -3,0,3,6,9,−3,0,3,6,9,minus, 3, comma, 0, comma, 3, comma, 6, comma, 9, comma
Answer:
12
Step-by-step explanation:
Given the arithmetic sequence :
-3,0,3,6,9
Using the relation :
Tn = a + (n- 1) d
d = common difference = t2 - t1 = 0 - (-3) = 3
The next term = 6th term ; n = 6
a = first term
T6 = - 3 + (6 - 1)3
T6 = - 3 + (5)3
T6 = - 3 + 15
T6 = 12
On considère les deux expressions A et B. A=4(x+5)-8 B=x au carré+15. Avec x=1,puis avec x=3, je trouve le même résultat pour A et B donc, quel que soit le nombre x, on a A = B. Emma a-t-elle raison ? Justifier la réponse.
Explication étape par étape:
Compte tenu des expressions ';
A = 4 (x + 5) -8
B = x² + 15
Nous devons vérifier si A = B pour les deux valeurs de x à x = 1 et x = 3
à quand x = 1
A = 4 (1 + 5) -8
A = 4 (6) - 8
A = 24-8
A = 16
B = x² + 15
B = 1² + 15
B = 1 + 15
B = 16
Donc à quand x = 1, A = B = 16
quand x = 3
A = 4 (x + 5) -8
A = 4 (3 + 5) -8
A = 4 (8) - 8
A = 32-8
A = 24
B = 3² + 15
B = 9 + 15
B = 24
Également lorsque x = 3, A = B = 24
Cela montre que le postulat d'Emmas est juste.
Find the domain and range please
Answer:

2 is the range.
please help ill mark brainliest if correct
The answer is A) (3.1, 2.2)
Answer:
A
Step-by-step explanation:
Given the 2 equations
y = 2x - 4 → (1)
2x + 4y = 15 → (2)
Substitute y = 2x - 4 into (2)
2x + 4(2x - 4) = 15 ← distribute and simplify left side
2x + 8x - 16 = 15
10x - 16 = 15 ( add 16 to both sides )
10x = 31 ( divide both sides by 10 )
x = 3.1
Substitute x = 3.1 into (1) and evaluate for y
y = 2(3.1) - 4 = 6.2 - 4 = 2.2
solution is (3.1, 2.2 ) → A
solve the system of equation
2x-y-3z=20
3x+y+6z=4
x+2y+9z=-16

Answer:
length of each is 51
Step-by-step explanation:
they are congruent triangles so they are equilateral
therefore, you can set 7x - 5 and 5x + 11 equal to each other and solve for 'x'
2x = 16
x = 8
Substitute 8 into each expression and both come out to be 51

is this the table u r trying to do??
Luna entered a raffle for a new pair of running shoes. She purchased 20 tickets and was told that she had a 20% chance of winning. How many tickets were sold? P (Luna winning) = StartFraction Number of tickets purchased over Total number of tickets sold EndFraction. 20 percent = StartFraction 20 over x EndFraction. One-fifth = StartFraction 20 over x EndFraction. x = tickets
Answer:
100 ticketsStep-by-step explanation:
Probability of winning = amount of tickets purchased/Total number of tickets
20% = 20/total number of tickets
20/100 = 20/total number of tickets
cross multiply
20 * total number of tickets = 20 * 100
20 * total number of tickets = 100
total number of tickets sold = 100 tickets
Answer:
100 tickets

Answer: 456 gramos.
Step-by-step explanation:
Con una busqueda online, encontré que la imagen relacionada con este problema es la que se ve abajo.
En ella podemos ver que el envase del producto trae dos porciones.
Entonces, si una porción tiene 228 gramos, dos porciones son:
2*228 g = 456 gramos.
Y el envase tiene dos porciones, entonces el envase tiene 456 gramos.

This formula gives the yearly depreciation D for
an item in terms of its cost C, its salvage value
S, and the number of years 71. Solve the
equation below for C.
C-S
De
Answer:
C = 71D + S
Step-by-step explanation:
The computation of the equation for C is as follows:
Given that
Yearly Depreciation = D
Cost = C
Salvage value = S
Number of years = 71
Based on the above information
The formula for the yearly depreciation i.e. D is
D = (C - S) ÷ 71
71D = C - S
71D + S = C
So, the equation would be
C = 71D + S

Answer:
y=1/4x+9
Step-by-step explanation:
x-4y=-36
add 4y to both sides to find x
x=4y−36
To find y=
add -x to both sides
−4y=−x−36
divide both sides by -4
y=mx+b
y=1/4x+9

Answer: x = 17
Step-by-step explanation:
180 - 94 = 86
So all the inside angles of a triangle = 180
180 - 86 - 60 = 34
34/2 = 17
Answer:
it's answer is 17
Step-by-step explanation:
we know exterior angle of a triangle is equal to the sum of two opposite interior angles. So,
2x + 60° = 94°
2x = 94° - 60°
2x = 34°
x = 34° /2
x = 17°
