Answer:(a) x - 0.7 = 1.5
Step-by-step explanation:
Determine whether each of the following is a solution of x − 0.7 = 1.5: (a) x = 1 (b) x = −0.8 (c) x = 2. Step 1. Substitute the number for the variable in the equation.
Step 2. Simplify the expressions on both sides of the equation.
Step 3. Determine whether the resulting equation is true.
If so, the number is a solution.
If not, the number is not a solution.
Supposed the profit from the sale of a product in a week is
P(x)=16x-100-0.1x²
There is a limit in the production of the product at 100 units for the week.
What level of production will yield a profit of $180
Step-by-step explanation:
180 =16x-100-0.1x2
-0.1x2+16x-280=0
x2-160x+2800=0
S=160
P=2800
DELTA=160*160-4*2800
DELTA=25600-10800

Answer:
Angle A is 62 degrees
Step-by-step explanation:
2x + 4 + x - 1 = 90 is the equation. Simplified it is 3x + 3 = 90. Solving the equation would make x = 29. Then, plug in x for each equation. Angle A is 62 degrees and Angle B is 28.

Convert the following quantities as shown.
(a) 24,000 volts to kilovolts
(b) 551 millivolts to volts
So, 24,000 v = how many kv
enter your response as kV - (Type a whole number or a decimal.)
a. 24 Kilovolts
b. 0. 551 Volts
How to convert the quantitiesIt is important to note that;
1000 volts = 1 Kilovolt
1000 millivolts = 1 volt
a. To convert 24,000 volts to kilovolts
If 1000 volts = 1 kilovolt
Then 24000 volts = x
cross multiply
x = 24000/ 1000
x = 24 Kilovolts
b. To convert 551 millivolts to volts
If 1000 millivolts = 1 volt
Then 551 millivolts = x
x = 551/ 1000
x = 0. 551 Volt
Thus, the values are 24 kilovolts and 0. 551 volt respectively

Two factors are multiplied, and their product is 32.3046. One factor is a whole number. How many decimal places are in the other factor? Tell how you know.
Step-by-step explanation:
a whole number has 0 decimal places (after the decimal point, meaning on the right side of the decimal point).
so, all the decimal places (4) must come from the other factor.
a multiplication by a whole number is always a series of additions of the other factor with itself. if anything, such a multiplication eliminates decimal places. it does not create additional ones.
e.g.
3.06 × 5 = 15.3 (because it is actually 15.30, but trailing 0s don't have any value like leading 0s, and are normally skipped).
the increase in the decimal places happens by involving places with higher value : 1/10 has a higher value than 1/100, that has a higher value than 1/1000, and so on.
so, e.g. 0.2×9 = 1.8 (and not 0.18).
as it is 2/10 × 9 = 18/10 = 1.8
an addition cannot create suddenly new decimal places with lower value.
therefore, normally we would say the other factor has 4 decimal places.
but in reality, it is a I said above, the 4 decimal places of the result of the multiplication "come from the other factor".
we cannot say that the other factor has 4 decimal places, because it could have more, and the multiplication with the whole number removed some.
e.g. 3.6 × 5 = 18 (or 18.0).
so,
32.3046 could be 6.46092 × 5
when we think this through, the other factor could have infinitely many decimal places.
like 5/9 × 108 = 0.555555... × 108 = 60
or our number
32.3046 could be 0.2991166666... × 108
so, all we can say, the other factor must have at least 4 decimal places.
What is an equation of the line that passes through the points (0,6)and (-5,2) ? Put
your answer in fully reduced form
Given that,
Points are (0,6) an (-5,2).
To find,
The equation of line that passes through the given points.
Solution,
We have, x₁ = 0, x₂ = -5, y₁ = 6 and y₂ =2
The equation of line can be calculated as :
[tex]y-y_1=m(x-x_1)\\\\y-6=\dfrac{2-6}{-5-0}(x-0)\\\\y-6=\dfrac{-4}{-5}x\\\\y-6=\dfrac{4}{5}x\\\\5y-30=4x\\\\5y-4x=30[/tex]
So, the required equation is 5y-4x=30.
