Answer:
P = k*q*r
Step-by-step explanation:
P = kqr
7 = k*2*1.5
7 = 3k
k = 7/3
b. P = kqr
= 7/3*4*6
= (7*4*6)/3
= 168/3
= 56
P = 56
c. P = kqr
1 = 7/3*q*3
1 = (7*q*3)/3
1 = 21q/3
Cross product
1*3 = 21q
3 = 21q
q = 3/21
= 1/7
q = 1/7
d. P = kqr
5 = 7/3*8*r
5 = (7*8*r)/3
5*3 = 56r
15 = 56r
r = 15/56

Use scientific notation to estimate the number of inches in 1,225 miles. Include all calculations in your final answer. 1 inch =1578x 10-5 miles
Answer: (7.129)*10^(7) inches.
Step-by-step explanation:
We know that:
1 inch = 1.578*10^(-5) miles.
If we divide both sides by 1.578*10^(-5), we get:
(1/1.578*10^(-5)) inches = 1 mile
63,371.36 inches = 1 mile
Now, we have 1,225 miles, this is equal to 1,125 times 63,371.36 inches
Then 1,225 miles writen in inches is:
1,125*(63,371.36 inches) = 71,292,780 inches.
Now, to write this in scientific notation, we need to count the number of decimals between the first one at the left, and the decimal point.
In this case we have 7 decimals.
Now, let's take the first 4 decimals, (7129) and write a decimal point after the first one:
(7.129)
Now let's multiply this by then to the power of 7 (where 7 is the number of decimals we found above).
Then the scientific notation of 71,292,780 inches. is:
(7.129)*10^(7) inches.

Which graph represents the equation 12 = 3x+ 4y? Explain how you know.
Graph A
Graph B
Graph C
Answer:
Step-by-step explanation:
3x%2B4y=12 Start with the given equation
4y=12-3x Subtract 3+x from both sides
4y=-3x%2B12 Rearrange the equation
y=%28-3x%2B12%29%2F%284%29 Divide both sides by 4
y=%28-3%2F4%29x%2B%2812%29%2F%284%29 Break up the fraction
y=%28-3%2F4%29x%2B3 Reduce
Looking at y=-%283%2F4%29x%2B3 we can see that the equation is in slope-intercept form y=mx%2Bb where the slope is m=-3%2F4 and the y-intercept is b=3
Since b=3 this tells us that the y-intercept is .Remember the y-intercept is the point where the graph intersects with the y-axis
So we have one point
Now since the slope is comprised of the "rise" over the "run" this means
slope=rise%2Frun
Also, because the slope is -3%2F4, this means:
rise%2Frun=-3%2F4
which shows us that the rise is -3 and the run is 4. This means that to go from point to point, we can go down 3 and over 4
So starting at , go down 3 units
and to the right 4 units to get to the next point
Now draw a line through these points to graph y=-%283%2F4%29x%2B3
So this is the graph of y=-%283%2F4%29x%2B3 through the points and

Find the slope and y intercept
Answer:
Slope is -2/9 and y intercept is (0,2)
Step-by-step explanation:
Answer:
slope: - [tex]\frac{2}{9}[/tex] y intercept: 2
Step-by-step explanation:
you need to rearrange the equation into a y=mx+b formation
m is always the slope b is always the y intercept
the new equation of would be
y=-[tex]\frac{2}{9}[/tex] x+2

The diameter of a cake is 12 centimeters, and the area of one slice of cake is 4\pi\ cm.^24π cm. 2 . In terms of \piπ, how many full slices can you cut out of the cake?
Answer:
Total number of slices = 9 slices
Step-by-step explanation:
Given:
Diameter of a cake = 12 cm
Area of one slice = 4π cm²
Find:
Total number of slices
Computation:
Radius of cake = 12 / 2 = 6 cm
Area of circle = πr²
Area of circle = π(6)²
Area of circle = 36π cm²
Total number of slices = Area of circle / Area of one slice
Total number of slices = 36π / 4π
Total number of slices = 9 slices
Answer:
9 full slices
