Answer:
17
Step-by-step explanation:
54 has 4 ones
and 5 tens
37 has 7 ones
and 3 tens
subtracting ones
7 ones are taken from 54
so along with the existing 4, 1 ten is decreased and another 3 ones are decreased resulting in 7 ones now
now 54 has 5-1= 4 tens
subtracting tens we get 4-3=1
Therefore 1 ten and 7 ones
⇒ 17
Hi there! The slope of the line is -2/5.
We can determine the slope of a line by dividing the change of y-coordinates by the change of x-coordinates.
In this situation we have a...
change of x-coordinates of (5 - 0) = 5
change of y-coordinates of (0 - 2) = -2
Therefore, the slope of this line is -2/5
Answer: 0.167
Step-by-step explanation:
This is an applied mathematics question
Resistors in parallel ⁾/R = ¹/₁₂₀ + ¹/₁₂₀ since the resistor is two 120
Therefore , resolve into fraction now yield
¹/R = 1 + 1
-------
120
= 2/120
= ¹/₆₀
Therefore, ¹/R = ¹/₆₀
Cross multiply to get R the resistance
R = 60
From formula, V = IR where I is the current
There fore making I the subject of the formula
I = V/R
= 10/60
= 0.166
= 0.167 A, A = ampere which is the unit of current.
Answer:
The amount invested in CDs is $1,340
The amount invested in the stock portafolio is $6,900
The amount invested in the saving accounts is $2,300
Step-by-step explanation:
Let
x ---->the amount invested in CDs at 2.1%
y ---> the amount invested in the stock portfolio at 2.5%
z ---> the amount invested in the savings account at 1.5%
----> equation A
----> equation B
substitute equation B in equation A
----> equation C
we know that
The total interest earned by the three amount must be equal to $231.69
so
----> equation D
substitute equation B and equation C in equation D
solve for y
<em>Find the value of x</em>
<em>Find the value of z</em>
