V = value
t = time ( number of years)
so V=1045 - 95t
to find the number of years to reach 0
0=1045-95t
1045=95t
t=11 years
Answer:
32÷8
Step-by-step explanation:
Division is like repeated subtraction
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The problem that would repeatedly take away 8 from 32 is 32÷8
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The same is true for 25÷5, it is asking how many times can 5 be taken away from 25, hence repeated subtraction
36 and 144
Explanation
Two Angles are Supplementary when they add up to 180 degrees
Step 1
Let
x= angle 1
y= angle2
The measure of one angle is four times the measure of the other angle,then
x and y are supplementary angles , then
Step 2
use Equation (1) and (2) to find x and y
replace Equation (1) in Equation (2)
replace the value of y= 36 in equation (1) to find x
Hence, the answer is 36 and 144

Answer:
-3
Step-by-step explanation:
The length of a segment is
sqrt( ( y2-y1)^2 + (x2-x1) ^2) = 2 sqrt(10)
sqrt( ( a-4 - -1)^2 + (2a -4) ^2) = 2 sqrt(10)
sqrt( ( a-4 +1)^2 + (2a -4) ^2) = 2 sqrt(10)
Combine like terms
sqrt( ( a-3)^2 + (2a -4) ^2) = 2 sqrt(10)
Square each side
( a-3)^2 + (2a -4) ^2) = 4 *(10)
FOIL the left side
a^2 -6a +9 + 4a^2 -16a +16 = 40
Combine like terms
5a^2 -22a +25 = 40
Subtract 40 from each side
5a^2 -22a -15 =0
Factor
(a - 5) (5 a + 3) = 0
Using the zero product property
a-5 =0 5a +3 = 0
a = 5 5a = -3
a=5 a = -3/5
The product of the terms is
5 * -3/5 = -3
