The rectangle is 16 inches by 25 inches. If the scale is 4 in :5 ft what is the length and width of the rectangle in feet.
Answer:
The length and width of the rectangle are 20 feet and 31.25 feet, respectively.
Step-by-step explanation:
Let the scale be [tex]4\,in\,:\,5\,ft[/tex] and the dimensions of the rectangle being 4 inches and 5 inches, respectively. The scale ([tex]r[/tex]), measured in inches per feet, is equivalent to the following rational number:
[tex]r = \frac{4\,in}{5\,ft}[/tex]
We can convert each length by dividing it by scale factor. That is:
Length
[tex]l' = \frac{16\,in}{\frac{4\,in}{5\,ft} }[/tex]
[tex]l' = 20\,ft[/tex]
Width
[tex]w' = \frac{25\,in}{\frac{4\,in}{5\,ft} }[/tex]
[tex]w' = 31.25\,ft[/tex]
The length and width of the rectangle are 20 feet and 31.25 feet, respectively.

Answer:
A
Step-by-step explanation:
Write the equation of the line that passes through the points (0,7) and (-4, -9).
Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal
line.
y=4x+7
First we need to figure out the slope. We can do that using the equation (y2-y1)/(x2-x1). Substitute your numbers in for the xs and ys:
(-9-7)/(-4-0)=
-16/-4=
4
Now that we have the slope, we can figure out the intercept by using the equation y=mx+b and substituting one of the points in for x and y, the slope in for m, and solving for b.
I’m going to use (0,7) as it will be faster:
7=4(0)+b
7=0+b
7=b
The full equation will then be:
y=4x+7
option D: 8 square root 3 cm

X and y intercept
Answer:
x intercept: (1,0)
y intercept: (0,3)
Step-by-step explanation: Substitute variables for 0 and solve
Answer:
y-intercept: 3
x-intercept: 1
Step-by-step explanation:
To find x-intercept:
1. make y equal to 0, leaving 9x=9
2. divide both sides by 9
3. x=1
To find y-intercept:
1. make x equal to 0, leaving 3y=9
2. divide both sides by 3
3. y=3

One hundred grams of radium are stored in a container. The amount RR (in grams) of radium present after tt years can be modeled by R=100e−0.00043tR=100e−0.00043t. After how many years will only 5 grams of radium be present? Round your answer to the nearest whole year.
Answer:
6967 years
Step-by-step explanation:
Given the exponential function :
R=100e−0.00043t
Time = t in years
R = final amount
Number of years in which only 5 grams of radium will be present :
R = 5
Plugging into our formula :
5 = 100 * e^−0.00043t
5 / 100 = e^−0.00043t
0.05 = e^−0.00043t
Take the In of both sides
−2.995732 = - 0.00043t
t = −2.995732 / - 0.00043t
t = 6966.819
t = 6966.819 years
t = about 6967 years
In the morning, a farm worker packed 3 pints of strawberries every 4 minutes. In the afternoon, he packed 2 pints of strawberries every 3 minutes. What was the difference between the morning and afternoon pack rates, in pints per hour?
A 5
B10
C40
D45
Answer:
A 5
Step-by-step explanation:
60 mins = 1 hour
60 divided by 4 is 15
60 divided by 3 is 20
15 times 3 is 45
20 times 2 is 40
45 - 40 is 5
If the resistance in an electrical cirouit is

For the expression 6 + y - 3, determine the coefficient for the variable term.
A -3 B 0 C 1 D 6
Explanation:
Think of 6 + y - 3 as 6 + 1y - 3
y and 1y are the same thing because 1 times any number is that same number.
The coefficient is the number to the left of the variable, so the coefficient is 1.

Answer:
y = -4
x = 3
Step-by-step explanation:
I will be using the elimination method to solve this:
Begin by times -1 to the bottom equation.
[tex]2x-3y=18[/tex]
[tex]-2x-y=-2[/tex]
Add them together
[tex]0x-4y=16[/tex]
ignore the 0x and divide -4 to both sides
[tex]\frac{-4y}{-4} =\frac{16}{-4}[/tex]
y = -4
Plug y back into one of the two original equations
[tex]2x-3(-4)=18[/tex]
multiply -3 and -4 to get +12
[tex]2x+12=18[/tex]
subtract 12 to both sides
[tex]2x=6[/tex]
divide by 2 to both sides
x = 3
