Answer: 3.5
Step-by-step explanation:
To solve for x in a square, you need to find the value of x that makes the square equal to zero. In this case, the square is given by (6x-21), so we can solve for x by setting this expression equal to zero and then solving for x.
To solve the equation (6x-21) = 0, we can use basic algebraic techniques. First, we can add 21 to both sides of the equation to get (6x-21) + 21 = 21. Then, we can use the distributive property to expand the left-hand side of the equation as follows:
(6x-21) + 21 = 21
6x - 21 + 21 = 21
6x = 21
Finally, we can divide both sides of the equation by 6 to find the value of x that makes the square equal to zero:
6x = 21
x = 21 / 6
x = 3.5
Therefore, the value of x that makes the square (6x-21) equal to zero is x = 3.5.

Answer:
The value of the machinery after 5 years is $236.20
Step-by-step explanation:
Generally, we have the depreciation exponential expression as;
V(t) = I (1 - r)^t
V(t) is the value of the machinery at a point in time
I is the initial value or the cost of the machinery when bought which is $400
r is the rate of decrease which is 10% and is same as 10/100 = 0.1
t is the time which is 5 years
Substituting these values;
V(5) = 400( 1 - 0.1)^5
V(5) = 236.196
to the nearest vent, this is $236.20

the parallelogram will have equal distances from center to along each diagonal. It is hard to explain with words and not being able to draw it.
So 2a+ 14 = 5a - 4 and a = 2b
solve the frist equation for a then the second equation for b
2a+ 14 = 5a - 4
18 = 3a
6 = a a = 2b 6 = 2b

Parker needs to buy bouquets for table centerpieces. Her client has a budget of $250. If the bouquets cost $14.95 each, which direct variation equation can you use to determine the number of flower bouquets Parker can purchase?
A. x=14.95y
B. y=250x
C.250=14.95x
D. y=250(14.95)
Answer:
C
Step-by-step explanation:
as stated by the questions, the client has a budget of $250, which means we can't exceed $250. This will be our y (dependent variable, as the cost for y depends on how many bouquets we will purchase).
the bouquets cost 14.95 each, so if we have x bouquets , that means that the cost will be 14.95x (independent variable, as this gives the value of y).
therefore, the equation is 250=14.95x, which is C
but let's do process of eliminiation to double check:
if we look at the options, B and D are out (the cost of the bouquets isn't $250 each and also we can't have 250 bouquets , that would be too expensive for the client).
that leaves A and C
A isn't the correct answer. At first glance, it looks like we just switched x and y around. However, it cannot work because x is always the independent variable while y is the dependent variable (the value of y depends on the value of x, while the value of x doesn't depend on y).
Also, there's no mention of the $250 budget in A
by process of elimination and by the explanation above C is the correct answer.
Hope this helps!

cos 25° = X/11
and
sin 65° = X/11
is this good enough or do you need more workings?
Answer:
C = 90°
Step-by-step explanation:
The interior angles in every triangle are equal to 180 degrees. So, this means that
[tex] \alpha + \beta + \gamma \\ = 180 \: degrees[/tex]
Which means that A + B +C = 180 degrees
A=25°
B = 65°
C =?
C = 180° - (A + B)
C = 180° - (25° +65°)
C = 180° - 90°
C = 90°

Molly's family traveled 5/8 of the distance to her uncle's house on Saturday. They traveled 1/3 of the remaining distance on Sunday. What fraction of the total distance to her uncle's house was traveled on Sunday?
Answer: [tex]\dfrac{1}{8}[/tex]
Step-by-step explanation:
Given
On Saturday, Molly's family traveled [tex]\frac{5}{8}[/tex] of the total distance
On Sunday, they traveled one-third of the remaining distance.
Suppose the total distance is x
Distance traveled on Saturday is [tex]\dfrac{5x}{8}[/tex]
Remaining distance is
[tex]x-\dfrac{5x}{8}=\dfrac{3x}{8}[/tex]
On Sunday, they travel
[tex]\dfrac{1}{3}\times \dfrac{3x}{8}=\dfrac{x}{8}[/tex]
fraction of total distance traveled on Sunday is [tex]\dfrac{1}{8}[/tex]

Two angles are complementary. One angle is 52°. How many degrees is the other angle?
Answer:
B
Step-by-step explanation:
Complementary angles sum to 90° then the other angle is
90° - 52° = 38°
Answer:
B 38°
Step-by-step explanation:
complementary angles are two angles that up to 90°, since we know one is 52°, 90-52=38, so your answer is 38
Alfredo tiene 36 cromos más que Iván, y si comprará 10 más , tendría el triple . ¿Cuantos cromos tiene cada uno?
Respuesta:
Alfredo = 59 pegatinas
Ivan = 23 pegatinas
Explicación paso a paso:
Dejar :
Pegatinas de Alfred = a
Pegatinas de Ivan = b
a = b + 36 - - - (1)
a + 10 = 3b- - - (11)
De 1)
a = b + 36
Ponga a = b + 36 en (11)
b + 36 + 10 = 3b
b + 46 = 3b
46 = 3b - b
46 = 2b
b = 23
a = b + 36
a = 23 + 36
a = 59
Alfredo = 59 pegatinas
Ivan = 23 pegatinas

Which statement(s) most directly apply to communism?

II. Businesses are operated for the benefit of the people as a whole.
III. Individuals who take risks can gain great profits.
a.
I and II
b.
II only
c.
II and III
d.
I and III
Please select the best answer from the choices provided
A
B
C
D
Answer:
A
Step-by-step explanation:
In the beginning, there was little or no private ownership. Cucumbers are a pretty interesting example. We had an exchange student who said all the cucumbers were raised on one collective the size of 10 sections. He didn't know how many people were on that farm but it employed many people. The farm was located near a very large city so transportation was not a problem. The state owned the farm.
The second one is a result of the first one. Collectives are not meant to benefit the individual. They benefit everyone.
Three is a characteristic of free enterprise.

5. Find the missing reference angle using arcsin, arccos, or arc tangent. (Round to
the nearest whole number)
14
48
50
Your answer
Answer:
16°
Step-by-step explanation:
Reference angle = [tex] \theta [/tex]
Side Opposite to reference angle = 14
Adjacent side = 48
Hypotenuse = 50
Let's apply arcsin:
Thus:
[tex] \theta = sin^{-1}(\frac{Opp}{Hyp}) [/tex] (recall: SOHCAHTOA)
Plug in the values
[tex] \theta = sin^{-1}(\frac{14}{50}) [/tex]
[tex] \theta [/tex] = 16.2602047° = 16°
