Answer:
4/9
Step-by-step explanation:
At t = 0 ; volume = 270
At t = 1.5 ; volume = 80
y = P(1 - r)^t
y =ab^x (exponential)
a = initial amout at t = 0
y = final amount
t = 1.5
80 = 270b^t
80/270 = b^t
8/27 = b^1.5
8/27 = b^3/2
b^3/2*2/3 = (8/27)^2/3
Cube root of 8/27 = 2/3
Square of 2/3 = (2/3)^2 = 4/9
The a question is attached below
Answer:
22.2m
Step-by-step explanation:
vol of a sphere = 4/3 x pi x r^3
vol of a hemisphere is 1/2 the vol of a sphere, so vol of a hemisphere= 2/3 x pi x r^3
2/3pi x r^3 = 257
Divide both sides by 2/3pi
r^3 = 122.708
Cube root both sides.
r = 11.077
Diameter is twice the radius, so diameter = 22.154m
To the nearest 10th of a meter this is 22.2m.

what is the equation of the trend line in the scatter plot ? HELP ME HURRY ILL MARK BRAINLIEST
Answer:
[tex] y = \frac{3}{7} x + 3 [/tex]
Step-by-step explanation:
Line is passing through the points (0, 3) and (7, 6)
So, y-intercept (b) = 3
Slope of the line (m) = (6 - 3)/(7 - 0) = 3/7
Equation of line in slope-intercept form is given as :
y = mx + b
Plugging the values of m and b in the above equation, we find:
[tex]y = \frac{3}{7} x + 3 \\ [/tex]

If the surface area of a cube is 384 square inches, what is the length of each side
Answer:
There are six equal surfaces of a cube. Then,
384 / 6 = 64 sq in (the area of one surface)
The area of one surface of a cube will be equal to x*x (if we let the edge length be x)
x^2 = 64
x = 8 inch

Find h. 11 in. h = [?] in. 1 1 1 14 in. Enter
Answer:
You know that the Pythagorean Theorem is:
a²+b²=c²
,
Where:
a
is the length of one of the legs,
b
is the length of the other leg, and
c
is the length of the hypotenuse.
You know the lengths of the two legs are
7 and 11
, so we'll say that
a is 7 , and b is 11
Knowing that, we can plug those into our equation and simplify like so:
7²+11²=c²
49+121=c²
170=c²
√170=c
c=13.0384
Answer:
√72Step-by-step explanation:
Use Pythagorean:

Use algebra, so
2m + 3s = 64 and also
4m + 2s = 72
Multiply the top equation by 2 so both have 4m, so
4m + 6s = 128 and also
4m + 2s = 72
Then minus the numbers form the top equation by the bottom equation, so
4m + 6s = 128
- - -
4m + 2s = 72
This gives you 4s=56 so divide by 4 so s=14
No put 14 into the equation for s and rearrange to solve for m, so
2m+3s=64 So
2m+3x14=64
2m+42=64
Then minus 42
2m=22
m=11

PLEASE HELP!! A circle is divided into three central angles that have measures in the ratio 2:13:15. find the measure of the largest angle.
Answer:
First angle = 24'
Second angle = 156'
Third angle = 180'
Step-by-step explanation:
Given:
Ratio of circles angle = 2:13:15
Find:
All three angle
Computation:
Sum of all angle from center = 360'
So,
First angle = 360[2/(2+13+15)]
First angle = 360[2/(30)]
First angle = 24'
Second angle = 360[13/(2+13+15)]
Second angle = 360[13/(30)]
Second angle = 156'
Third angle = 360[15/(2+13+15)]
Third angle = 360[15/(30)]
Third angle = 180'

Answer:
d=101
Step-by-step explanation:
If 11 is being multiplied by t, and t is 11, we multiply 11 by 11, we get 121.
After adding that to our equation, we get -20 + 121, which equals 101.
Therefore d=101
The value of d, when t = 11 is equal to 141.
What is a function?
An expression in mathematics defines a relationship between one variable (the independent variable, x) and another variable (the dependent variable, y). For example -
f(x) = 4x + 6
Given is the following equation -
d = - 20 + 11t
We have -
d = - 20 + 11t
for t = 11, we get -
d = 20 + 11 x 11
d = 20 + 121
d = 141
Therefore, the value of d, when t = 11 is equal to 141.

-22 - 49 = -71
Answer:
23
-71
Step-by-step explanation:
11 - (-12) = ?
-22 - 49 = ?
11 - ( -12) = 11 + 12 = 23
-22 - 49
subtracting a negative from a negative is like adding a positive to a positive it has the same affect just a different sign
-22 - 49 = -(22 + 49)
22 + 49 = 71
-(71) = -71
