On a given planet, the weight of an object varies directly with the mass of the object. Suppose that an object whose mass is 9kg weighs 63 N . Find the weight of an object whose mass is 5kg.
Answer:
35
Step-by-step explanation:
9Kg =63N
5Kg=X (Cross Multiple)
=X×9 =5×63
divide both sides by 9
X=5×63
---------
9
=35
Answer:
35 N
Step-by-step explanation:
let w = weight of object
and m = mass of object
w = mk where k is the constant of proportion
63 = 9k
k = 7
So, w = 7m
w = 7(5) = 35 N

If the discriminant of an equation is positive, which of the following is true of the equation
A it has one complex solution
B it has one real solution
C it had two real solutions
D it has two complex solutions
Answer:
C it has two real solutions
Step-by-step explanation:
If the discriminant of a quadratic equation is positive, it means that the graph intersects the x-axis, and hence produces two real solutions.
If the discriminant is zero, then the graph is tangential to the x-axis, and there will be two real coincident solutions.
If the discriminant is negative, then there are two complex solutions.
Answer:
C
Step-by-step explanation:
a triangle has a side length of 5.4 and 7 x x=
Answer:
D. 8.8
Step-by-step explanation:
As the pythagorean theorem.
A² + B² = C²,
5.4 × 5.4 + 7 × 7 = C²,
29.16 + 49 = C²,
78.16 = C²,
8.8 ≈ C

Is -2 rational or irrational?
Answer:
Rational
Step-by-step explanation:
Rational. It can be expressed as a fraction, which is the definition of a rational number.
Hope this Helps!
-2 is rational
This is because every negative integer is a negative rational number.
We know that -1 = -1/1, -2 = -2/1, -3 = -3/1, -4 = -4/1 and so on …….
In other words, any negative integer n can be written as n = n/1, here n is negative and 1 is positive.
So, negative 2 is rational.
Part A: Mike wants to join a gym. He has to pay an initiation fee of $16 and equal monthly payments for the year. The most he wants to pay is $580 for the year for his gym membership. a.) Write an inequality that you can use to determine the most he would want to spend for his monthly payments.
Part B: Now use your inequality from 15a to determine how much Mike’s monthly gym payment can be if the most he wants to pay is $580 for the year for his gym membership..
Answer:
Part A: [tex]12x+16\leq 580[/tex]
Part B: $47 per month
Step-by-step explanation:
Part A: 12 months in a year. Pays x amount of $ per year, with an additional $16 initiation fee. He wants to spend less than $580 total a year. Thus, [tex]12x+16\leq 580[/tex].
Part B: Solve the inequality for x.
$580 - $16 = $564
x = $564/12 = $47

Answer:
x = 50°
Step-by-step explanation:
The triangle has 3 congruent sides and is therefore equilateral.
The 3 angles are then congruent, each 60°
The left angle in the quadrilateral is adjacent to 60° of the triangle
180° - 60° = 120° ← angle inside quadrilateral
The sum of the interior angles of a quadrilateral = 360°
Subtract the sum of the angles from 360° for x
x = 360° - (120 + 90 + 100)° = 360° - 310° = 50°
What’s the value of x?

Customer- I recently saw an advertisement that said your company would give 5% discount to anyone who enrolls in your automatic payment plan, my monthly bill is $75 how much will I save if I enroll?
Answer: $3.75
Step-by-step explanation:
The amount that you would save is 5% of your monthly bill of $75.
This amount is:
= 75 * 5%
= $3.75
The total amount that you would pay is:
= 75 - 3.75
= $71.25

Andrea uses 9.8 pints of white paint and blue paint to paint her bedroom walls. 1 4 of this amount is white paint, and the rest is blue paint. How many pints of blue paint did she use to paint her bedroom walls?
Answer:
7.35
Step-by-step explanation:
Andrea uses 9.8 pints of white and blue paints to paint her bedroom walls
1/4 of this amount is white paint
= 1/4 × 9.8
= 0.25×9.8
= 2.45
Therefore the amount of blue paint can be calculated as follows
9.8-2.45
= 7.35
Hence 7.35 are blue paint

Trey bought 3 and 3 fourths pounds of apples from the grocery store. Corinne bought 1 and 1 third pounds of grapes from the grocery store. How many more pounds of fruit did Trey buy
Answer: 2 5/12
Step-by-step explanation:
Trey bought 3¾ pounds of apples from the grocery store. Corinne bought 1⅓ pounds of grapes from the grocery store.
To know how many more pounds of fruit that Trey bought, we have to find the difference between the value given above and this will be:
= 3¾ - 1⅓
= 3 9/12 - 1 4/12
= 2 5/12
Trey bought 2 5/12 pounds more.
