Answer:30 divided by 5 = 6
Step-by-step explanation:
Answer:
5
Step-by-step explanation:
6 = 30/x
multiply both sides by x
6x = 30
divide both sides by 6
x = 30/6 = 5

which two ratios form a proportion
A 1:2 and 4:2
b 1:2 6:3
c2:1 2:4
d 2:1 and 6 :3
Answer:c
Step-by-step explanation:
Did the test
Answer:
D. 2:1 & 6:3
Step-by-step explanation:
Proportion means equal so we need to see which ratios are equal.
To do that we need to make one fo the numbers in the ratio equal the corresponding number in the other ratio, then see if the other matches.
A:
1:2 & 4:2
The second number is already the same but the first isn't, therefore it is not proportional.
B:
1:2 & 6:3
To get 1 to equal 6 we must multiply it by 6, and what you do to one side you must do to the other so we have to multiply 2 by 6 as well
6:12 & 6:3
The first numbers are the same but the second isn't, therefore it is not proportional.
C:
2:1 & 2:4
The first numbers are the same but the second isn't, therefore it is not proportional
D:
2:1 & 6:3
to get 2 to equal 6 we need to multiply it by 3, which means we have to multiu 1 by 3 too
6:3 & 6:3
These are equal so this is proportional.

The table shows your scores in a skateboarding competition. The leader has 311.62 points. Select the equation that you can use to find how many points p you need in the fourth round to tie the leader. Then solve the equation to determine how many points you need in the fourth round to take the lead in the competition.
Find the second part please.
Answer:
✅[tex] p + 63.43 + 87.15 + 81.96 = 311.62 [/tex]
✅To take the lead, your score in the fourth round must be greater than 79.08.
Step-by-step explanation:
If you score, 63.43, 87.15, 81.96 in the first, second and third round respectively, if the current leader has a total score of 311.62 points, the point p that you need to score to equal 311.62 points, can be found using the following equation:
[tex] p + 63.43 + 87.15 + 81.96 = 311.62 [/tex]
Solve for the value of p
[tex] p + 232.54 = 311.62 [/tex]
Subtract 232.54 from each side
[tex] p = 311.62 - 232.54 [/tex]
[tex] p = 79.08 [/tex]

Jeremy is solving this system of equations algebraically. Which equation could be a step in his work? y=3x+1 4x-3y=-13
Answer: c
Step-by-step explanation:
I did it
The solution for the system of equations → y = 3x + 1 and
4x - 3y = -13 is (2, 7)
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written as -
Ax + By + C = 0
By = - Ax - C
y = (- A/B)x - (C/A)
Given is the system of equations as -
y = 3x + 1
AND
4x - 3y = -13
Plot the graph of both of these equations. The point of intersection, would be the solution of this system of equations. Refer to the graph attached. These lines intersect at (2, 7)
Therefore, the solution for the system of equations → y = 3x + 1 and
4x - 3y = -13 is (2, 7)

If a random sample of 47 steel bolts is selected, what is the probability that the sample mean would differ from the population mean by more than 0.2 millimeters?
Complete Question
Thompson and Thompson is a steel bolts manufacturing company. Their current steel bolts have a mean diameter of 143 millimetres, and a standard deviation of 5. If a random sample of 47 steel bolts is selected, what is the probability that the sample mean would differ from the population mean by more than 0.2 millimetres? Round your answer to four decimal places.
Answer:
The probability is [tex]P(|\= x - \mu | \ge 0.2 ) = 0.78394[/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 47
The mean diameter is [tex]\mu = 143[/tex]
The standard deviation is [tex]\sigma = 5[/tex]
Generally the standard error of the mean is mathematically represented as
[tex]\sigma_{x} = \frac{\sigma }{\sqrt{n} }[/tex]
=> [tex]\sigma_{x} = \frac{5 }{\sqrt{47} }[/tex]
=> [tex]\sigma_{x} = 0.7293[/tex]
Generally the probability that the sample mean will differ from the population mean by more than 0.2 milli meters is mathematically represented as
[tex]P(|\= x - \mu | \ge 0.2 ) = P(\frac{|\= x - \mu|}{\sigma_{x}} \ge \frac{0.2}{0.7293} )[/tex]
[tex]\frac{|\= x - \mu | -\mu}{\sigma } = |Z| (The \ standardized \ value\ of \ {|\= x - \mu | )[/tex]
=> [tex]P(|\= x - \mu | \ge 0.2 ) = P(|Z| \ge 0.2742 )[/tex]
=> [tex]P(|\= x - \mu | \ge 0.2 ) = P(Z < - 2742) + P(Z > 0.2742)[/tex]
From the z table the area under the normal curve to the left corresponding to -2.742 is
[tex]P(Z < -0.2742) =0.39197[/tex]
From the z table the area under the normal curve to the right corresponding to 2.742 is
P(Z > 0.2742) = 0.39197
So
[tex]P(|\= x - \mu | \ge 0.2 ) = 0.39197 + 0.39197[/tex]
[tex]P(|\= x - \mu | \ge 0.2 ) = 0.78394[/tex]
frank is going to plant b vegetable seeds in one garden and 4b + 2 vegetable seeds in another. How many seeds is frank going to plant?
Answer:
5b + 2
Step-by-step explanation:
Frank is going to plant b vegetable seeds in one garden and 4b + 2 vegetable seeds in another.
We need to find how many seeds is frank going to plant.
It is equal to the sum of vegetable seeds in one garden and the vegetable seeds in another.
Sum = b + 4b + 2
Sum = 5b + 2
So, there are "5b + 2" seeds frank going to plant.

$45
?
A. 4h : $36
O
B. 54lbs : 6 OZ
o
4h
$50
D.
$63
9h
Answer:
A.) 4h : $36
Step-by-step explanation:
Why it's right: they equal the same thing
5/45 = 1/9
4/36 = 1/9
Why it's wrong: similar, but backwards
54/6 = 9
Just plain wrong:
4/50 = 2/25
63/9 = 7
In order to lure new customers to a credit card, a bank is offering an initial cash back award, plus cash back amounting to a percentage of the value of all purchases made with the card the value of all purchases made with the card and the amount of cash back which of these equations does the graph represent ?
Answer:
A. [tex] c = 0.03p + 150 [/tex].
Step-by-step explanation:
The equation can be written in slope-intercept form as [tex] c = mp + b [/tex], where:
c = cash back (dollars)
p = value of purchases (dollars)
m = slope of the graph
b = y-intercept, which is the initial cash back award.
All we need to generate an equation that represents the graph, we need to find out the value of m and b.
b = until cash back award = 150
The slope, m, can be calculated using two points in the line, (1000, 180) and (2000, 210):
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{210 - 180}{2000 - 1000} = \frac{30}{1000} = 0.03 [/tex]
Substitute m = 0.03, and b = 150, in [tex] c = mp + b [/tex].
The equation would be:
✅ [tex] c = 0.03p + 150 [/tex].

Answer:
After expanding the polynomial [tex](3c + 2)(c^2-6c-4)[/tex] we get [tex]3c^3-16c^2-24c-8[/tex]
Step-by-step explanation:
We need to expand the polynomial [tex](3c + 2)(c^2-6c-4)[/tex]
Multiply the terms:
[tex](3c + 2)(c^2-6c-4)\\=3c(c^2-6c-4)+2(c^2-6c-4)\\=3c^3-18c^2-12c+2c^2-12c-8\\=3c^3-18c^2+2c^2-12c-12c-8\\=3c^3-16c^2-24c-8[/tex]
So, after expanding the polynomial [tex](3c + 2)(c^2-6c-4)[/tex] we get [tex]3c^3-16c^2-24c-8[/tex]
