what is the mass of an object that weighs 7 kg and 50 N?
Answer:
7kg
Step-by-step explanation:
mass: amount of matter in a substance,
SI Unit: kg
It has nothing to do with N (weight) in this case so take the kg value as the mass
Answer:
0.71 kg
Step-by-step explanation:
a common equation in physics is w = mg
we can rearrange this to m = w/g
g is the acceleration of gravity: 9.81 m/s^2
w is the weight of the given equation of the object: 7 kg
so m = 7 kg ÷ 9.81 m/s^2
this gives us: m = 0.71 kg

310= -6.2f
I’m just struggling on this question;—;
Answer:
Step-by-step explanation:
sup. so what you're going to do is divide -6.2 on both sides to get f by itself
310/-6.2= -6.2f/-6.2
f=-50
Answer:
-50.
Step-by-step explanation:
310 = -6.2f
To solve for f we divide both sides of the equation by -6.2
310 / -6.2 = -6.2f / -6.2
f = -310/-6.2 = -50.

Change 8 1/2 to an
improper fraction.
Answer:
17/2
Step-by-step explanation:
Answer:
17/2
Step-by-step explanation:
Improper fraction means no whole number. So, we have to change 8 to a fraction with a common denominator as 1/2. So, 8/1 = 16/2, plus the given 1/2, that's 17/2.

1. D
-4x + 2y = 8 ⇒ -2x + y = 4 ⇒ y = 2x + 4Parallel line has same slope of 2y = 2x - 52. H
Slope is: (2-4)/(3-(-3)) = -2/6 = -1/3Perpendicular line has negative reciprocal slope: -1/3 → 3 y = 3x - 23. G
Slope is: (2 - (-2))/(0 - (-1)) = 4/1 = 4Parallel line has same lope of 4y = 4x - 74. B
3x + y = 1 ⇒ y = -3x + 1Perpendicular line has negative reciprocal slope: -3 → 1/3y = 1/3x + 28. Which of the following is the 43rd term of the arithmetic sequence 3,0-3, ...?
A-117
B 120
C. -123
D. -126
Answer:
C
Step-by-step explanation:
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 3 and d = a₂ - a₁ = 0 - 3 = - 3 , thus
a₄₃ = 3 + (42 × - 3) = 3 - 126 = - 123 → C
Answer:
C. -123.
Step-by-step explanation:
nth term = a1 + d(n - 1)
43rd term = 3 + -3(43-1)
= 3 - 126
= -123.

choose whether you would find the percent increase or percent decrease: The marching band had 304 students last year. This year, 322 students participate in band. *
PLSSSS HELP ILL GIVE BRAINLIST!!!
Answer:
Percent increase
Step-by-step explanation:
Since the number of marching band students increased from 304 to 322, you would find the percent increase.
You wouldn't find the percent decrease because the number of students increased.
Answer:
the percent has increased, and if your looking for the amount increase in percentage its 5.92%

P(-,3) , Q(7,-3) and R (4,1) are three points. show that PQ=2QR using distance formula. (please show the steps too :)
Answer:
PQ is 10.
QR is 5.
Hence, PQ=2QR
Step-by-step explanation:
We have the three points P(-1, 3); Q(7, -3); and R(4, 1).
And we want to show that PQ=2QR.
In other words, we want to show that PQ/QR=2.
So, let's find PQ and QR. We will need to use the distance formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]
To find PQ:
P is (-1, 3) and Q is (7, -3).
So, we will let P(-1, 3) be (x₁, y₁) and Q(7, -3) be (x₂, y₂).
Substitute the values into the distance formula. This yields:
[tex]d=\sqrt{(7-(-1))^2+(-3-3)^2[/tex]
Evaluate:
[tex]d=\sqrt{(8)^2+(-6)^2[/tex]
Evaluate:
[tex]d=\sqrt{64+36}=\sqrt{100}=10[/tex]
So, the distance of PQ is 10.
And to find QR:
Q is (7, -3) and R is (4, 1).
Again, we will let Q(7, -3) be (x₁, y₁) and R(4, 1) be (x₂, y₂).
Substitute appropriately. So:
[tex]d=\sqrt{(4-7)^2+(1-(-3))^2[/tex]
Evaluate:
[tex]d=\sqrt{(-3)^2+(4)^2[/tex]
Evaluate:
[tex]d=\sqrt{9+16}=\sqrt{25}=5[/tex]
So, the distance of QR is 5.
Therefore, it follows that:
[tex]\displaystyle PQ=2QR\Rightarrow \frac{PQ}{QR}=2\Rightarrow\frac{10}{5}\stackrel{\checmark}{=}2[/tex]
And we have shown that PQ=2QR.

A jar has 32 marbles. Some are blue and the rest are green. There are three times as many green marbles as blue. How many green marbles are in the jar
Answer: 24
Step-by-step explanation:
Number of marbles in jar = 32
Let blue marbles be represented by b.
Since there are three times as many green marbles as blue. This means that green will be = 3 × b = 3b
We then add them together. This will be:
3b + b = 32
4b = 32
b = 32/4
b = 8
There are 8 blue marbles
Since green is 3× blue. Therefore,
Green = 8 × 3 = 24 marbles

y varies directly with x. y is 84 when x is 16. What is the constant of proportionality? (Write answer as improper fraction...Remember to reduce!)
Answer: 5 1/4
Step-by-step explanation:
We use the formula for direct proportion to solve the question since we are informed that y varies directly with x and that y is 84 when x is 16.
The formula will be:
y = kx
where,
y = 84
x = 16
We then slot the values into the formula
y = kx
84 = 16k
k = 84/16
k = 5 1/4
The constant of proportionality is 5 1/4

A group of 5 friends decide to set up a lemonade stand. They sell 48 cups of lemonade for $1.35 each. If they split the amount of money they made evenly, how much does each friend take home?
Answer:
Step-by-step explanation:
There are a couple of ways you could do this. The first and most obvious way is just to find out what the total amount is and divide by 5
48 cups * $1.35 / cup = $64.80 total
Now divide by 5
$64.80 / 5 = 12.96 for each person.
The other way to do it is just to divide 1.35 by 5 = 0.27
Now multiply by 48 to get each person's share.
0.27 * 48 = 12.96
Take your pick. The answer is the same either way.
