Your friend's math test contained 42 questions, some of which were worth two points while therest were worth three points.Your friend tells you that a perfect score is 100 points, but shecannot remember how many of each type (2 point or 3 point) were on the test.Help your friendout:how many of each type were on the test?
Answers
Answer: Two points = 26
Three points = 16
Step-by-step explanation:
Let the 2 points questions be represented by x
Let the 3 points questions be represented by y
Since the math test contained 42 questions, some of which were worth two points while therest were worth three points. This can be written as:
x + y = 42 ........... equation i
Since a perfect score is 100 and some questions are worth two pints while others are worth 3 points. This can be written as:
2x + 3y = 100 ........... equation ii
x + y = 42 ........... equation i
2x + 3y = 100 ......... equation ii
Multiply equation i by 2.
Multiply equation ii by 1
2x + 2y = 84 ........ equation iii
2x + 3y = 100 ....... equation iv
Subtract equation iii from iv
y = 16
There are 16 3-points questions.
Since x + y = 42
x + 16 = 42
x = 42 - 16
x = 26
There are 26 2-points questions

Answers
Answer:
1. [tex]V =1607.7\ in^3[/tex]
2. [tex]V = 105mm^3[/tex]
3. [tex]V = 147yd^3[/tex]
Step-by-step explanation:
Solving (1):
Given
[tex]Radius, r =8\ in[/tex]
[tex]Height, h =8\ in[/tex]
Required
Determine the volume
Volume (V) of a cylinder is calculated as thus:
[tex]V =\pi r^2h[/tex]
[tex]V =3.14 * 8^2 * 8[/tex]
[tex]V =1607.7\ in^3[/tex]
Hence, the volume of the cylinder is [tex]1607.7\ in^3[/tex]
Solving (2):
Given
[tex]Length, l = 5mm[/tex]
[tex]Width, B = 7mm[/tex]
[tex]Height, H = 3mm[/tex]
Required
Determine the volume (V) of the rectangular prism
Volume (V) of a rectangular prism is calculated as thus:
[tex]V = LBH[/tex]
[tex]V = 5mm * 7mm * 3mm[/tex]
[tex]V = 105mm^3[/tex]
Hence, the volume of the prism is [tex]105mm^3[/tex]
Solving (3):
Given
[tex]Length, l = 7yd[/tex]
[tex]Width, B = 7yd[/tex]
[tex]Height, H = 9yd[/tex]
Required
Determine the volume (V) of the pyramid
Volume (V) of a pyramid is calculated as thus:
[tex]V = \frac{1}{3} *LBH[/tex]
[tex]V = \frac{1}{3} * 7yd * 7yd * 9yd[/tex]
[tex]V = \frac{1}{3} * 441yd^3[/tex]
[tex]V = 147yd^3[/tex]
Hence, the volume of the pyramid is [tex]147yd^3[/tex]

Answers
Answer:
y=12x+10
Step-by-step explanation: First you start off with PEMDAS and multiply 12 times x and -1. Which you'll have y - 2 = 12x - 12. Next you'll subtract 2 by both sides and your answer will be y = 12x -10
Answer:
y = 1/2x + 1 1/2
Step-by-step explanation:
Slope-intercept form is written with the formula [ y = mx + b ].
Solve for y.
y - 2 = 1/2(x - 1)
y - 2 = 1/2x - 1/2
y = 1/2x + 1 1/2

−6.5>6.55
−6.5≥6.55
−6.5<6.55
−6.5=6.55
Answers
Answer:
6.5 < 6.55
Step-by-step explanation:
since
6.5 can be written as 65/10
6.55 can be written as 655/100
when we take LCM of 100 and 10 we get 100.
so we will multiply 65/10 with 10 on both numerator and denominator.
we get 650/100 and 655/100 .
since denominators are same we can say that 650<655.
Hence,
6.5 < 6.55

Which of these constructions would construct a line of reflection that takes point A to point B?
Construct the perpendicular bisector of segment AB.
Construct a line through B perpendicular to segment AB.
Construct the line passing through A and B.
Construct a line parallel to line AB.
Answers
Answer:
2nd choice because the first wouldnt make sense because of the angle it is in
Step-by-step explanation:
We have that the constructions which would construct a line of reflection that takes point A to point B is Option D
Construct a line parallel to line AB
A line parallel to line AB will Create a line of reflection that takes point A to point B because a parallel line never meet thereby creating the direct imagery of Line AB
From the Options
We have that
-Construct the perpendicular bisector of segment AB.
A perpendicular bisector will NOT Create a line of reflection that takes point A to point B but rather it will divide the line AB in two equal parts
-Construct a line through B perpendicular to segment AB.
A line through B perpendicular to segment AB will NOT Create a line of reflection that takes point A to point B
-Construct the line passing through A and B.
A line passing through A and B will NOT Create a line of reflection that takes point A to point B but rather will create Line A and B again and not its reflection
Construct a line parallel to line AB
A line parallel to line AB will Create a line of reflection that takes point A to point B because a parallel line never meet thereby creating the direct imagery of Line AB
In conclusion
The constructions which would construct a line of reflection that takes point A to point B is Option D
Construct a line parallel to line AB
A line parallel to line AB will Create a line of reflection that takes point A to point B because a parallel line never meet thereby creating the direct imagery of Line AB

In an electrical circuit ,the voltage across a resistor is directly proportional to the current running through the resitor.If a current of twelve amps produces 480 volts across a resistor,how many volts would a current of 1.5 amps produce across an identical resitor?
Answers
Answer: The voltage across an identical resistor = 60 Volts
Step-by-step explanation:
Step 1
Given that voltage across the resistor is directly proportional to the current running through the resitor.
Mathematically, it would be represented as
Voltage ∝ Current
Introducing the constant of proportionality, k which represents the Resistor as it is constant.
we have that
Voltage = K x Current
When current = 12 amps and voltage = 480v, the constant of proportionality K
480 = k x 12
k = 480/12
k= 40
Step 2 ,
when current = 1.5 amps
Voltage = ?
Using our equation that
Voltage = K x Current
Voltage = 40 x 1.5
Voltage = 60 Volts

what is the answer to this? −1.3≥2.9−0.6r
Answers
Answer:
Inequality Form:
r ≥ 7
Interval Notation:
[7, ∞)
Step-by-step explanation:
−1.3 ≥ 2.9 − 0.6r
Rewrite so r is on the left side of the inequality.
2.9 − 0.6r ≤ −1.3
Move all terms not containing r to the right side of the inequality.
Subtract 2.9 from both sides of the inequality.
−0.6r ≤ −1.3 − 2.9
Subtract 2.9 from −1.3.
−0.6r ≤ −4.2
Divide each term by −0.6 and simplify.
Divide each term in −0.6r ≤ −4.2 by −0.6. When multiplying or dividing both sides of an
inequality by a negative value, f lip the direction of the inequality sign.
−0.6r /−0.6 ≥ −4.2 /−0.6
Cancel the common factor of −0.6.
−4.2
r ≥ ______
−0.6
Divide −4.2 by −0.6.
r ≥ 7
The result can be shown in multiple forms.
