Is -6.743743… a rational or irrational number?
Your answer:
Rational because .743 repeats
Rational because the 6 is negative
Irrational because the number never ends
Irrational because the 6 is negative
It's rational because it contains a repeating digit pattern, 743 (first option).
In particular, if
x = -6.743743…,
then
1000x = -6,743.743743… .
Subtracting, we can eliminate the trailing end and solve for x exactly:
1000x - x = -6,743.743743… - (-6.743743…)
999x = -6,737
x = -6,737/999

Work out the number of years of investment for each return.
a. £3000 invested at 3% simple interest returns £3720
Answer:
41 years approx
Step-by-step explanation:
Given data
P= £3000
R=3%
Simple Interest= £3720
Time=???
We know that from the simple interest expression
SI= PRT/100
substitute
3720= 3000*3*T/100
Make T subject of the formula
T= 3720*100/3000*3
T= 372000/9000
T= 41.33
Hence the number of years is 41 years approx
1). There are 25 students in grade 7. 15 are boys and others are girls. A
student is selected for a field trip at random.
A) Find the probability of selecting a boy
B) Find the probability of selecting a girl|
Answer: 1) 15:25 or 15/25 2) 10:25 or 10/25
Step-by-step explanation: if there are 25 students total and there are 15 boys that means the rest are girls so 25-15 is 10 girls. So the ratio for selecting a boy would be 15:25 or 15/25 and the ratio for selecting a girl would be 10:25 or 10/25

A triangle where one angle measures 20° and another angle measures 45°.Help please
Answer: 115 degrees
Step-by-step explanation:
Pretty vague question but with the info given im guessing that your looking for the last angle in the triangle which is 115 since all angles in a triangle must add up to 180
Can someone tell me which equation this is
1. f(x)= 1/4x +4
2. y=1/2x +4
3. f(x)=-2/3 +4
Answer:
#3
Step-by-step explanation:
The line follows an inverted slope format, indicated by -2/3. Or down 2, and 3 to the right after going up by 4, creating the line. The other equations would flip the line horizontally because of a positive slope.

Two Forest Ranger stations are located 9.8 miles apart. They both receive the same distress call. They determine that from Ranger Station 1 the distress call is at an angle of 46° and from Ranger Station 2 it is at angle of 52°. Which ranger station is closer to the distress call and by how much?
Answer:
Ranger station 2 is closer by 3.47 miles
Step-by-step explanation:
tan(46)=O/9.8
O (ranger station 2 to distress call)=10.15 miles
sin(46)=9.8/H
H (ranger station 1 to distress call)=13.62 miles
13.62-10.15=3.47 miles
So, ranger station 2 is closer by 3.47 miles

3(x - 7) = 2(x - 12)
explain how u got it too
Answer:
x = -3
Step-by-step explanation:
3x - 21 = 2x - 24
3x = 2x - 3
x = -3
Answer:
x = 45
Step-by-step explanation:
First, we need to use the distributive property on both sides of the equation. We multiply the number outside of the parentheses by every term inside the parentheses.
3(x - 7) = 2(x - 12)
3x - 21 = 2x - 24
From here, we solve for x.
3x - 21 = 2x - 24
x - 21 = 24 (Subtract 2x from both sides)
x = 45 (Add 21 to both sides)

A company produces fruity drinks that contain a percentage of real fruit juice. Drink
A contains 20% real fruit juice and Drink B contains 15% real fruit juice. The
company used 100.5 liters of real fruit juice to make 30 more liters of Drink A than
liters of Drink B. Write a system of equations that could be used to determine the
number of liters of Drink A made and the number of liters of Drink B made. Define
the variables that you use to write the system.
Answer:
x = amount of real fruit juice used to make Drink A
y = amount of real fruit juice used to make Drink B
Step-by-step explanation:
Let
x = amount of real fruit juice used to make Drink A
y = amount of real fruit juice used to make Drink B
1. The company used 100.5 liters of real fruit juice, then
2. Drink A:
x = amount of real fruit juice used
percentage of real fruit juice
Then
5x = amount of drink A produced
Drink B:
y = amount of real fruit juice used
percentage of real fruit juice
Then
amount of drink B produced
The company makes 30 more liters of Drink A than liters of Drink B, so
The system of two equations is

Write an equation of a line that goes thru the points (-2, 6) & (3, -4)
Answer:
The equation of the line is;
y = -2x + 2
Step-by-step explanation:
Here, we want to write the equation of the line that passes through the given points
The general form of the equation is
y = mx + b
where m is the slope of the line and b is the y-intercept of the line
Mathematically, to get the slope, we use the slope formula
m = (y2-y1)/(x2-x1)
(x1,y1) = (-2,6)
(x2,y2) = (3,-4)
m = (-4-6)/(3+2) = -10/5 = -2
So the equation is in the form;
y = -2x + b
To get b, we substitute any of the two points
6 = -2(-2) + b
6 = 4 + b
b = 6-4 = 2
The equation of the line is thus;
y = -2x + 2
What is the slope between the points (-1,3) and (2, 5)?
Answer:
2 is the slope
you have to use this: y2-y1
x2-x1
y2= 5 y1= 3
x2= 2 x1= -1
5-3=2
2-1=1
In circle O, chords AC and BD intersect at E. If MCD= 120 and MAB=100, what is BEC?
Answer:
D. 70°Step-by-step explanation:
∠BEC is supplementary with ∠BEA
Find the measure of ∠BEA
m∠BEA = 1/2(mCD + mAB)m∠BEA = 1/2(120° + 100°) = 110°Supplementary angles sum to 180°
m∠BEC + m∠BEA = 180°m∠BEC = 180° - 110° = 70°Correct choice is D

4 and 6
3 and -8
-4 and -21
4 and 36
4 and -7
Step-by-step explanation:
1)
4 + 3 = 7
4 × 3 = 12
2)
4 + 5 = 9
4 × 5 = 20
3)
4 + 6 =10
4 × 6 = 24
4)
3 - 8 = -5
3 × (-8) = -24
5)
-4 - 21 = -25
-4 × (-21) = 84
6)
4 + 36 = 40
4 × 36 = 144
7)
4 - 7 = -3
4 × (-7) = -28
Use kite WXYZ to find m<YZQ
(2/3) to the 3rd power] plus [(3/4) to the zero power]
Answer:
1-8/27
Step-by-step explanation:
[tex](\frac{2}{3})^3=\frac{8}{27}[/tex]
[tex](\frac{3}{4})^0=1[/tex] (anything to the zeroth power is 1)
[tex]1+\frac{8}{27}=1\frac{8}{27}[/tex]
We cannot simplify, so 1-8/27 is our answer.
