The half-life of a radioactive kind of iodine is 60 days. How much will be left after 240 days, if you start with 480 grams of it?
Answer:
30 grams
Step-by-step explanation:
half life is 60 days so every 60 days the amount 480 grams will be half
in 240 days will decay 240 /60 = 4 times
once 480 /2 = 240
twice 240 /2 = 120
trice 120 / 2 = 60
four times 60/2 = 30 grams will be left
FAST ILL MARK U BRAINLIEST Write an equation of the line that passes through (2, −1) and is parallel to the line 2y + 3x = 8 . Write your answer in slope intercept form.
Answer:
y=[tex]-\frac{3}{2}[/tex]+2
Step-by-step explanation:
for an equation to be parallel with another both should have the same rate of change(m).
the line given to us is in general form, and we can change it to slope-intercept form to get the slope. (y=mx+b)
Isolate for y:
2y+3x=8
2y=-3x+8
y=-3/2x+8/2
y=-3/2x+4
thus the slope of the line we are trying to find must also equal -3/2
use point slope form to find the equation (substitute (2, -1) into equation)
y-y1=m(x-x1)
y-(-1)=(-3/2)(x-2)
y+1=[tex]-\frac{3}{2}[/tex]x+3
y=[tex]-\frac{3}{2}[/tex]+2
???????????????i didn’t learn this what’s the answer ?
Answer:
24 inches squared
Step-by-step explanation:
That is a triangle, and the area of a triangle is 1/2(b)(h), which is one half times the base times the height. Let's identify those things.
1/2: the area of a rectangle can be calculated base times the height, and a triangle is half of that rectangle, hence the 1/2
(b) or base: base is usually identified as the horizontal line in the triangle, which is 6 inches in this case.
(h) or height: height is usually the vertical line, and in this case, the vertical line is 8 inches.
Now time for the math:
1/2(6)(8) = 24 inches squared
help me please. real answers only. Write an equation for the line parallel to the given line that contains C.
C(2,8); y = - 4x + 5
y =
(Type your answer in slope-intercept form.)
Answer:
y = -4x + 16
Step-by-step explanation:
The slope of the given line is -4
when two lines are parallel, their slopes are equal
That means the slope of the second line is -4 too
Thus, we have to use the point-slope form to write the equation
That will be
y-y1 = m(x-x1)
y-8 = -4(x-2)
y -8 = -4x + 8
y = -4x + 8+8
y = -4x + 16

Find the product of ( 2x^2 − 4x + 3 ) ( 3x + 6 ) using the box method shown below. What will the monomial be in the box marked with a B?
Select one:
a. - 12x 2
b. - x 2
c. - x
d. - 12x
Answer:
It should be A. -12^2
Step-by-step explanation:
Looking at the box B, you have to multiple 3x and -4x. 3 * -4 is -12 and the two x's become squared. Making your answer -12x^2

what is m∠2 if m∠6 = 120°?
Answer:
I love ur pfp
Step-by-step explanation:
ANSWER: m∠2 = 120°, m∠3 = 60°; Sample answer: ∠1 and ∠2 are alternate exterior angles, so they have the same measure. ∠2 and ∠3 are supplementary. So, m∠3 = 180° – 120° or 60°.

1. Water vapor given off by water, plants, and animals is called ?
A. evaporation
B. precipitation
C. condensation
D. runoff
Answer:
evaportation
Step-by-step explanation:
The vapor given off by water, plants, and animals is called evaporation.
What is evaporation?Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. High concentration of the evaporating substance in the surrounding gas significantly slows down evaporation, such as when humidity affects rate of evaporation of water.Given is to find what does the water vapor given off by water, plants, and animals is called.
Evaporation is defined as the conversion of water into water vapour (into gas phase) and its release into the atmosphere. Similarly, the Water vapor given off by water, plants, and animals is called evaporation.
Therefore, the vapor given off by water, plants, and animals is called evaporation.

QUICK PLZ!!! Use the number line below, where RS = 6y + 3, ST = 4y + 7, and RT = 60.
Step-by-step explanation:
[Diagram in image attached]
RS + ST = RT
(6y +3) + (4y + 7) = 60
6y + 3 + 4y + 7 = 60
10y + 10 = 60
10y = 60 - 10
10y = 50
y = 50/10
y = 5
RS = 6y +3 = 6(5) + 3 = 30 + 3 = 33
ST = 4y +7 = 4(5) + 7 = 20 + 7 = 27
RT = 60
{RS + ST = RT
33 + 27 = 60}

Howe Moving Company has a loading ramp for their moving truck. The ramp connects to the truck 5 feet above the ground, and the length of the ramp from the truck to the ground is 13 feet long. What is the distance along the ground from the truck to the end of the ramp?
Answer:
12 feet
Step-by-step explanation:
Given that,
The ramp connects to the truck 5 feet above the ground, and the length of the ramp from the truck to the ground is 13 feet long.
Now we need to find the distance along the ground from the truck to the end of the ramp.
Here,
5 feet will be perpendicular distance, 13 feet will be hypotenuse and we need to find the base.
Using Pythagoras therorem to find it :
[tex]b=\sqrt{13^2-5^2} \\\\=12\ \text{feet}[/tex]
So, the required distance is 12 feet.
Answer:
12 feet!!
