Answer:
[tex]6 \times {10}^{3} = 6000[/tex]
Step-by-step explanation:
[tex](1.5 \times {10}^{ - 6} ) \times (4 \times {10}^{9} )[/tex]
[tex] = (1.5 \times 4) \times ( {10}^{ - 6} \times {10}^{9} )[/tex]
[tex] = 6 \times ( {10}^{ - 6} \times {10}^{9}) [/tex]
[tex] = 6 \times {10}^{ - 6 + 9} [/tex]
[tex] = 6 \times {10}^{3} [/tex]

Can someone please explain how to find a cofunction with the same value as the given expression. Please explain step by step.
Ex. How would you find the cofunction of sin 7°
Answer:
Step-by-step explanation:
-the angles need to add to 90° because they have to e complementary
- the cofunctions come in pairs (sin and cos, tan and cot, sec and csc)
for sin 7°
we know that function sin is paired with cos , and that the angles needs to add to 90° so we have 7° + 83° =90°
sin 7° = cos 83°, cos 83° is a cofunction of sin 7°

Solve for f.
–9(–2f − 8) = –6f
f =
Answer:
f = - 3
Step-by-step explanation:
Given
- 9(- 2f - 8) = - 6f ← distribute left side
18f + 72 = - 6f ( add 6f to both sides )
24f + 72 = 0 ( subtract 72 from both sides )
24f = - 72 ( divide both sides by 24 )
f = - 3

Just expand the brackets carefully
a total of $10,000 is invested in two funds, Fund A and Fund B. Fund A pays 5% annual interest and Fund B pays 7% annual interest. The combined annual interest is $630. How much of the $10,000 is invested in Fund A?
The amount of the 10000 invested in each Fund A is $5,300
First step is to calculate the amount invested in Fund B
Let x represent the amount invested at 7%
.07x+.05(10000-x)=630
Open the bracket
.07x+500-.05x=630
Collect like terms
.02x=630-500
.02x=130
x=130/.02
x=$6,500
Second step
Now let calculate How much of the $10,000 is invested in Fund A
Fund A amount invested=10000-6500
Fund A amount invested=$3500
Inconclusion The amount o of the 10000 invested in each Fund A is $5,300

Step-by-step explanation:
The following equation can be used to relate the speed time and distance of an object in motion,
[tex](Speed)*(Time)=(Distance)[/tex]
One can also rewrite this equation in terms of time:
[tex](Speed)=\frac{(Distance)}{(Time)}[/tex]
Let this equation represent the relation between Mr.Wang's initial speed and travel time. However, in this problem, Mr.Wang faced a decrease in his speed, more specifically, a (20%) decrease. Subtract (0.2) from (1) to find Mr.Wang's speed in relation to his original speed. Let (x) represent the increase in time that Mr. Wang had to incur in order to reach his destination. Model this situation,
[tex](Speed)*(Time)=(Distance)[/tex]
[tex]0.8(Speed)*x(Time)=(Distance)[/tex]
Now use inverse operations to solve for the coefficient (x):
[tex]0.8(Speed)*x(Time)=(Distance)[/tex]
[tex]x(Time)=\frac{(Distance)}{0.8(Speed)}[/tex]
Using the relation state above: ([tex](Speed)=\frac{(Distance)}{(Time)}[/tex]) one can state the following:
[tex]x(Time)=\frac{(Distance)}{0.8(Speed)}[/tex]
[tex]x(Time)=\frac{1}{0.8}(Time)[/tex]
Thus, (Time) can be omitted from this equation, as it appear on both sides as a factor, hence one can then solve for (x):
[tex]x(Time)=\frac{1}{0.8}(Time)[/tex]
[tex]x=\frac{1}{0.8}[/tex]
Divide (1) by (0.8):
[tex]x=\frac{1}{0.8}\\x=0.25[/tex]
Multiply the decimal by (100) to put it into the percent form:
[tex]x=0.25\\x=25\%[/tex]
The model below represents an equation. What value of x makes the equation true?

Jon has to pay $7.00 admission for the skating rink in $1.50 per hour to rent rollerblades. How many hours can he skate for $19?
Answer: 8 hours
Step-by-step explanation:
Given information
Admission fee = $7.00
Hour rent fee = $1.50
Number of hours = h
Total fee = $19
Set equation according to the given information
Total fee = admission fee + (hours) × (hour rend fee)
Substitute values into the equation
19 = 7 + 1.5h
Subtract 7 on both sides
19 - 7 = 7 + 1.5h - 7
12 = 1.5h
Divide 1.5 on both sides
12 / 1.5 = 1.5h / 1.5
[tex]\boxed{h=8}[/tex]

A teacher has 104 pieces of candy if there are 13 students in the candies divided evenly how many pieces will each student get
Every student will get 8 candies.
What is division?Division is a process of splitting a specific amount into equal parts.
Given that, A teacher has 104 pieces of candy, which she equally divides to her 13 students.
Therefore, for calculating how many candies each of them is getting, we will divide total number of candies to the total number of students,
Therefore, 104/13 = 8
Hence, we get that every student will get 8 candies.

(Putting values of b = 1/2 and c = 1/4)
[tex] = 8( \frac{1}{2} \div 2) - ( \frac{1}{4} + 4)[/tex]
[tex] = 8( \frac{1}{2} \times \frac{1}{2} ) - ( \frac{1 + 16}{4} )[/tex]
[tex] = 8 \times \frac{1}{4} - \frac{17}{4} [/tex]
