In the system of equations, a and b are constants. if the system has infinitely many solutions, what's the value of ab?
Answer:
The system has infinitely many solutions when a = 3/4 and b = 1/2Given
System of linear equations
ax +by = 163x+2y=64To find Values of a and b that leads to infinitely many solutionsSolutionThe linear system of equations has infinitely many solutions when lines overlap, so both have same slope and y-intercept.
We can solve it in two different ways
1. Note that when the first equation is multiplied by 4, it has same value of constant as the second equation, which is 64.
4ax + 4by = 643x + 2y = 64When compared it gives us:
4a = 3 ⇒ a = 3/44b = 2 ⇒ b = 2/4 = 1/22. Convert both equations from standard to slope-intercept form and compare:
ax + by = 16by = -ax + 16y = - (a/b)x + 16/b3x + 2y = 642y = - 3x + 64y = - (3/2)x + 32Work out values of a and b:
16/b = 32 ⇒ b = 16/32 ⇒ b = 1/2- (a/b) = - 3/2 ⇒ a/b = 3/2 ⇒ a = 3b/2 ⇒ a = 3(1/2)/2 ⇒ a = 3/4What is the volume of the cone shown below?

1 peasant changed rabbits to hens and 2 rabbits were equal to 3 hens, each hen produced the eggs that were equal to ⅓ of the total number of hens, the peasant sold the eggs, 9 eggs will cost as many pennies as each hen that produced the eggs and totally he got 72 pennies so how many hens and how many rabbits he had?
The peasant had 28 hens and 42 rabbits
How to determine the number of hens and rabbits?Represent hens with h, eggs with e and rabbits with r.
So, we have:
2r = 3h
e = 1/3h
Make h the subject in e = 1/3h
h = 3e
He got 72 pennies.
So, we have:
r + h = 72
Multiply through by 2
2r + 2h = 144
Substitute 2r = 3h in 2r + 2h = 144
3h + 2h = 144
Evaluate the sum
5h = 144
Divide by 5
h = 28.8
Remove decimal
h = 28
Recall that:
2r = 3h
So, we have:
2r= 3 * 28
Divide by 2
r = 3 * 14
Evaluate the product
r = 42
Hence, the peasant had 28 hens and 42 rabbits

A car drives at a speed of 90 km/h for 2 hours and 20 minutes
How far does the car drive?
Answer:
210km
Step-by-step explanation:
2hours = 180km
2hours = 120minutes
40mins =180/3
=60km
20mins=60/2
=30km
2h and 20mins =30+180
=210km
Answer:
210kms
Step-by-step explanation:
Speed of the car per hour = 90km/h
or, speed of the car per minute = 90/60kms=1.5km/minute
Now,
car drives for 2hours and 20 minutes
or, (2*60 +20) minutes= 140minutes
Distance of the car drive= minutes travelled* speed per minute
= 140*1.5kms
=210kms

Triangle N P O is shown. Line O N extends through point M to form exterior angle P N M. Angle N P O is 38 degrees. Angle P O N is 39 degrees. Exterior angle P N M is x degrees.
Which statement about the value of x is true?
x > 38
x < 39
x < 77
x > 103
The correct option is Option A: x > 38° this statement about x value is true.
Given in triangle ΔNPO the angle ∠ PNM is the exterior b to the interior angle ∠ PNO of the triangle.
Given the angle ∠NPO= 38°
∠PON= 39°
As we know the exterior angle is the sum of the two farthest interior angles of the triangle.
Then we can write the angle ∠PNM as
So, ∠PNM = ∠NPO + ∠PON
⇒ x = 38° + 39° = 77° {Given that ∠ PNM = 38° and ∠ PON = 39°}
{Since the exterior angle of an interior angle is equal to the sum of the other two interior angles of a triangle}
As x=77°
which satisfies the relation x=77° >38°.
Therefore,The correct option is Option A: x > 38° this statement about x value is true.

The angle measurements the carpenter needs to cut the carpet to make it fit in his room are 144°, 144°, 144°, 144°, 144°, 90°, and 90°
Angles in a polygonFrom the question, we are to determine the angle measurements that the carpenter needs to cut the carpet to make it fit in his room
The diagram shows a heptagon with two of its angles, a right-angle each, and the remaining angles have equal values, x.
First, we will calculate the sum of angles in a heptagon
The sum of angles in a polygon is given by the formula
Sum of angles in a polygon = (n-2)180°
Where n is the number of sides
For a heptagon, n = 7
∴ Sum of angles in a heptagon = (7-2)180°
= 5×180°
= 900°
Now, considering the given diagram, we can write that
x + x + x + x + x + 90° + 90° = 900°
5x + 180° = 900°
5x = 900° - 180°
5x = 720°
x = 720°/5
x = 144°
Hence, the angle measurements the carpenter needs to cut the carpet to make it fit in his room are 144°, 144°, 144°, 144°, 144°, 90°, and 90°

The denominator (the bottom part of the fraction will be the amount of kids at the party, 8) and the top part, the numerator, will be 6 as there are 6 girls at the party of the 8 attendees.
So the fraction is 6/8. However we can reduce this by dividing both sides of the fraction by a common factor, 2!

Answer:
The ratio of sides of triangle = 13:14:15
perimeter = 84 CM
perimeter of a triangle = Sum of all sides
let the sides of a triangle be 13x, 14x and 15x
84 = 13x + 14x + 15x
84 = 42x
x = 2
13x = 13* 2 = 26 CM
14x = 14*2 = 28 CM

Answer:

The given relations can be used to write two equations describing the coins. One equation can express the total number of coins; the other, their total value.
__
setupLet d and q represent the numbers of dimes and quarters, respectively. The the total number of coins is ...
d + q = 25
and their total value is ...
0.10d +0.25q = 5.20
solutionUsing the first equation to write an expression for d, we can substitute that into the second equation.
d = 25 -q
0.10(25 -q) +0.25q = 5.20
0.15q = 2.70 . . . . . . . . . collect terms, subtract 2.50
q = 18 . . . . . . . . . . . divide by 0.15
d = 25 -q = 7
