Step-by-step explanation:
the 2 shaded rows on the top are both 10 and the bottom shaded row is 5 so the equation would be 2×10+5
Answer:
0.25
Step-by-step explanation:
The model represents one whole number (1)
Each square represents .01 of the whole number.
So if you add all the shaded squares together, you would get 25 shaded, which means the answer would be 0.25
hope this helps :)

X/4 -3 = 1/3 + 2x solve for x
Answer:
Step-by-step explanation:
[tex]\frac{x}{4}[/tex] - 3 = [tex]\frac{1}{3}[/tex] + 2x ...... (1)
(1) × 12 :
3x - 36 = 4 + 24x
21x = - 40
x = - [tex]\frac{40}{21}[/tex] = [tex]-1\frac{19}{21}[/tex]

Write the equation of a line that safely lands the plane. Press submit to see if the plane lands safely.
Answer:
[tex] y = \frac{3}{4}x - \frac{1}{4} [/tex]
Step-by-step explanation:
First, find the slope using the points (3, 2) and (-1, -1):
Slope = [tex] m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-1 - 2}{-1 - 3} = \frac{-3}{-4} = \frac{3}{4} [/tex]
Find the y-intercept, b, by substituting x = -1, y = -1 and m = ¾ in y = mx + b.
-1 = ¾(-1) + b
-1 = -¾ + b
Add ¾ to both sides
-1 + ¾ = b
(-4 + 3)/4 = b
-¼ = b
Substitute m = ¾ and b = -¼ in y = mx + b.
The equation would be:
✅[tex] y = \frac{3}{4}x - \frac{1}{4} [/tex]

There are 10 computers and 5 students. How many ways are there for the students to sit at the computers if no computer has more than one student and each student is seated at a computer?
Answer:
30,240 ways
Step-by-step explanation:
This question is bothered on permutation. Permutation has to do with arrangement.
If there are 10 computers and 5 students, the number of ways students will sit at the computers if no computer has more than one student can be expressed as;
10P5 = 10!/(10-5)!
10P5 = 10!/(5)!
10P5 = 10*9*8*7*6*5!/5!
10P5 = 10*9*8*7*6
10P5 = 30,240
Hence the number of ways is 30,240 ways

Find the time it takes for $9,200 to double when invested at an annual interest rate of 10%, compoun
continuously.
years
Find the time it takes for $920,000 to double when invested at an annual interest rate of 10%, compounded
continuously.
years
Answer:
years = natural log (total / principal) / rate
years = natural log (18,400 / 9,200) / 10
years = natural log (2) / 10
years = 0.69314718056 / 10
years = 6.9314718056
and this would be the time for ANY amount of money to double.

Convert to slope intercept form: 3x-4y=8 then graph the line on the grid
Answer:
y=3/4x-2
a=(8/3,0)
b=(0,-2)
m=3/4
Step-by-step explanation:
STEP 1
3x-4y =8 substract 3x from both sides
-4y=-3x+8 divide -4 to everything
y=3/4x-2
STEP 2
substitute 0 for y and solve for a (x-intercept)

I'll give brainliest if you answerrr! A seesaw is in balance when a weight times its distance on one side of the fulcrum is equal to another weight times its distance on the other side of the fulcrum. In the diagram, the 20-lb. weight is 5 feet from the fulcrum and another weight is 8 feet from the fulcrum. Using the in-balance seesaw shown, find the number of pounds in the weight represented by N.
Answer:
12.5
Step-by-step explanation:
The 20 lbs on the left side time the 5 feet is equal to 100.
You need the weight on the right side to equal 100 when it is multiplied to it's length from the fulcrum, which is 8.
All you need to do is divide 100 by 8, to get 12.5.
Order the numbers from least to greatest.

The length of one side of a square is 3n+2. The perimeter of the square is 4(3n+2). Which expression is equivalent to the perimeter
Answer:
4(3n + 2)
Step-by-step explanation:
as we know perimeter of a square is 4 x side
one side is 3n + 2
4 sides = 4(3n +2)
