6. All angles in the figure below are right angles. What is the area of the figure? (1 point)
Answer:
Option (4)
Step-by-step explanation:
Area of the figure given in the picture = Area of large rectangle - Area of rectangle A
Area of rectangle A = Length × Width
= [9 - (2 + 4)] × 3
= 3 × 3
= 9
Area of the large rectangle = Length × Width
= 9 × 5
= 45
Therefore, area of the given figure = 45 - 9
= 36
Option (4) will be the correct option.

Mila buys 1112 pound of almonds and 56 pound of pecans.
Need this fast!
Which answer is the most accurate estimate for how many more pounds of almonds she buys than pounds of pecans?
A. 0 pounds
B. 12 pound
C. 1 pound
Answer:
B. 12 pounds
Step-by-step explanation:
All of them are off but if I had to choose an answer between those three I would choose B.
If you round 1112 to 1000 and 56 to 60, and do 1000 divided by 60 you get 16.6
Out of all the answers 12 pounds is closest to 16.
This is how I would answer it. Hope this helps!

Write a verbal sentence then solve the equation. The quotient of X and 6 is 8.7
Answer
6/x = 8.7
Step-by-step explanation:
let x = a number that we will find out
6/x = 8.7 (determinethe defined range)
6/8 = 8.7, x = 0 (multiply both sides)
6 = 8.7x (swap sides)
8.7 x = 6 (divide both sides)
x = 20/29
check
x = 20/29, x = 0
OR x = 0.689655

Zeke has swim club every 2 days and robotics club every 8 days.
This month, he has swim club on the 2nd day of the month and robotics club on the 8th day of the month.
Zeke says that the first time he will have both clubs on the same day is the 16th day of the month because the LCM of 2 and 8 is 16.
Answer: No. Zeke found the LCM to be the product of two and eight but because eight is a multiple of two the LCM is eight so the first day he will have both clubs is the 8th day of the month
Step-by-step explanation:
All you have to do is fine the least common multiple of 2 and 8 which is eight so obviously zeke is incorrect because they said the least common multiple was 16 and it is not. zeke multiplied 2 and 8 which is not what you’re supposed to do to get the lcm.

Step-by-step explanation:
Whats a line passing
through the
points (0, 0) and
(5,-7)?
Answer:
y = -7/5x
Step-by-step explanation:
First, we need to use the two points to find the slope.
m = y₁ - y₂ / x₁ - x₂
m = -7 - 0 / 5 - 0
m = -7/5
Now we know that the slope is -7/5. Now we'll substitute the information we've gathered into the point-slope form equation to get an equation.
y - y₁ = m(x - x₁)
y - (-7) = -7/5(x - 5)
y + 7 = -7/5x + 7
y = -7/5x
Therefore, the equation of the line is y = -7/5x.

[tex]\frac{n}{7}[/tex] - 12 = 5n + 5
I need to show my work, please.
Answer:
n= -3.5
Step-by-step explanation:
n/7 - 12 = 5n +5
+12 +12
n/7 = 5n+17
*7 *7
n = (5n+17)*7
n = 35n + 119
-35n -35n
-34n = 119
/-34 /-34
n = -3.5
