WHAT IS THE x-intercept of the graph?
A red-light flashes every 28 seconds. A green light flashes every 24
seconds. They both flash at the same time. After how many seconds will
they both next flash at the same time
Answer:
168 seconds
I edited the answer.
Step-by-step explanation:
To find the the time taken for both lights to flash at the same time, we need to find the lowest common multiple of 28 and 24.
28 x 6 = 168, 24 x 7 = 168
The LCM of 28 and 24 is 168.
So it takes 168 seconds for both lights to flash at the same time.
Both lights will flash together again at 2 minutes and 8 seconds.
To find When will they flash together again if they flash together.
What is LCM?LCM is the method to find the smallest possible multiple of two or more numbers.
Given that,
A red light flashes once every 28 seconds
A green light flashes once every 24 seconds
A red light flashes every 28 seconds and green light flashes once every 32 seconds. Therefore, we have to find their least common factor.
LCM(28 , 24) = 168
The red and green light will flash together after every 168 seconds.
Time =168 seconds
Time =168 / 60 minutes
Time = 2 minutes and 8 seconds
The red and green light will flash together after every 2 minutes and 8 seconds.
Hence, both lights will flash together again at 2 minutes and 8 seconds.

Answer:
[tex]\frac{6}{25}[/tex] - [tex]\frac{8}{25}[/tex] i
Step-by-step explanation:
Assuming you mean
[tex]\frac{2i}{-4+3i}[/tex]
To simplify, rationalise the denominator
Multiply the numerator/ denominator by the conjugate of the denominator
The conjugate of - 4 + 3i is - 4 - 3i , then
= [tex]\frac{2i(-4-3i)}{(-4+3i)(-4-3i)}[/tex] ← expand numerator and denominator
= [tex]\frac{-8i-6i^2}{16-9i^2}[/tex] [ note that i² = - 1 ]
= [tex]\frac{-8i+6}{16+9}[/tex]

Andy mailed a third package weighing 2.5 pounds did the third package way more or less than the first package describe how you used place value blocks to compare the weights
The weights of the first and second packages are :
First package = 2.48 pounds
Second package = 2.6 pounds
Answer:
3rd is greater Than first.
Step-by-step explanation:
Weight of third package = 2.5 pounds
Comparing the weight of first and 3 rd package :
2.5 > 2.48
Weight of 3rd package > Weight of first package
First package :
2.48 pounds
Third package :
2.50 pounds
Greatest place value of the package weight is the unit value, 2 ; since the unit value is the same, we take the 2nd highest place value of the weight ;the tenth
Value of the tenth digit = 4
Value of the tenth digit in third package = 5
Since, 5 > 4 ; then 3rd weight package is greater than first weight package

A circle has a circumference of 6. It has an arc of length 1.
What is the central angle of the arc. in degrees?
Answer:
60°Step-by-step explanation:
Given that:
Circumference (C) = 6 unitsArc length (A) = 1 unitFind the central angle (θ)
Arc is some part of circumference; thus,
the equation of arc length =
A = θ/360 × C
θ/360 = A/C
θ = (360×A)/C
θ = (360×1)/6
θ = 360 ÷ 6
θ = 60° ✅Central angle = 60°

What is the probability of rolling an even number on the first roll of a number cube and rolling an odd number on the second roll?
Answer:
1/4.
Step-by-step explanation:
There are 3 even numbers in the 6 numbers on a cube.
So Probability first roll is even = 3/6 = 1/2.
By the same reason Probability of odd number = 1/2.
So: Probability(First is even and second is odd) = 1/2 * 1/2 = 1/4.

What is the surface area of the regular pyramid below?

O A. 544 sq. units
B. 304 sq. units
OC. 256 sq. units
D. 184 sq. units
The total surface area of the given pyramid is 304 sq units.
What is pyramid?A pyramid is three dimensional shape. A pyramid has a polygonal base and flat triangular faces, which join at a common point called the apex.
Every face of the pyramid is triangular except the base. The base is square shaped. So we will use the formula of area of triangle to find the area of each face of the pyramid. And we will use the formula of area of square to find the base area of the pyramid.
The area of triangle is = (1/2)×base×height
The are of square = (side)²
Given that the length and breadth of base is = 8 units
So, the area of base is = 8²=64 sq units.
Also the height of the each triangular face is 15 units.
So, the area of each face is = (1/2)×8×15
=4×15
=60 sq units.
So, the total area of four triangular faces of the pyramid = 4×60
=240 sq units.
Hence, the surface area of the pyramid = Area of four traingular faces + Area of square base
=240+64
=304sq units
Thus , The required surface area of the pyramid is = 304 sq units
