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
Joshua unfolded a cardboard box. The figure of the unfolded box is shown below:
Which calculation will give the total surface area of the cardboard, in square inches, that was used to make the box? (1 point)
Question 14 options:
1)
6 × 3 × 3
2)
3 × 6 × 6
3)
9 × 6 × 6
4)
6 × 9 × 9
Answer:
1) 6 * 3 * 3
Step-by-step explanation:
Assuming the box is a cube, the surface area would be 6 times one side's area (since in a cube each side is a square) or A=6s^2 where s is a side length of the cube. This means that the surface area is 6*3*3=6*9=54 in^2
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)
n is less than or equal to 13
Answer:
n ≤ 13
Step-by-step explanation:
≤ is a symbol used to show less than or equal to. Since n is less than or equal to 13, you will put it like n ≤ 13.

what is the probability of rolling a standard die twice and getting an even number, then 5?
Answer: 22.222% or .2222
Step-by-step explanation:
There are 6 sides on a standard die. Two of the numbers (1&4) are perfect squares so the chances of getting a perfect square on the first roll is 2/6. There are 4 numbers less than 5 (1,2,3,4). The chances of rolling a number less than 5 on the second roll is 4/6. The probability of two events is equal to the product of those events or in this case 2/6 x 4/6 which is 8/36. Which reduces to 2/9. That’s 22.222% or .2222

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
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
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.

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

(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.

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
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
