How many square feet of outdoor carpet will
we need for this hole?
?
3 ft
Ift
2 ft
4 ft
2 ft
12 ft
Answer:
40 sq feet
Step-by-step explanation:
(im bad at explaining)
1 x 2 = 2 sq ft
3 x 2 = 6 sq ft
4 x 12 = 48 sq ft
2 sq ft + 6 + sq ft = 8 sq ft
48 - 8 = 40
The amount of outdoor carpet needed = area of the largest rectangle in the image - (area of medium rectangle + area of the smallest rectangle) = 40 ft².
What is the Area of a Rectangle?Area of a rectangle = lenght × width.
The amount of square feet of outdoor carpet needed = area of the largest rectangle in the image - (area of medium rectangle + area of the smallest rectangle)
The amount of square feet of outdoor carpet needed = 12 × 4 - (3 × 2 + 2 × 1)
The amount of square feet of outdoor carpet needed = 48 - (6 + 2)
The amount of square feet of outdoor carpet needed = 40 ft²

Purchased Amount Paid Egg Plant 3 lb $ 21 Beetroot 5 lb $ 28 Which vegetable costs more per pound?
Answer:
eggplant cost more/pound.
Step-by-step explanation:
ep= 7$/pound
br= 5.6$/pound
That the Egg Plant costs more.
My reasoning for this is because if you do 21 divided by 3 it equals 7 which means each pound of Egg Plant is $7. But 28 divided by 5 is 5.60. Which means, Beetroot is $5.60 per pound! So, beetroot is less than the Egg Plant!
Find the area of the figure please
Answer:
16m
Step-by-step explanation:
Separate the rectangle from the triangle. The area of the rectange is 10m. We know this because l x w (2m x 5m).
Now for the triangle;
The area of a triangle is b x h / 2. We take the full height of the figure and subtract 5 from it giving us 3 which is our height for the triangle. We then see that 2m is on the bottom and we add that 2m to the two separate 1m giving us 4m in total.
Now that we have the base and height of the triangle we plug in giving us 6m. Finally we add both the areas; 10m + 6m = 16m.

Find all possible values of x for which these two triangles are similar.
Answer:
I see no solution.
Step-by-step explanation:
The sum of the angles of a triangle is 180°
Given
x+ x + 10 +y = 180. and
2x -50 + 50 + y = 180
y represents the angles with no value indicated.
Simplifying:
2x +y +10 = 180
2x + y = 180
This looks like a no solution system.
If I'm missing something, I hope someone else can explain it.
The two triangles are similar when two angles of the triangle are equal.
The possible value of x which the two triangles are similar is x = 60°
Reasons:
Required;
To find the values of x for which the two triangles are similar
Method:
Given that two angles of the triangle are specified, the triangles can be
similar for only one value of x.
Solution:
The two triangles are similar when we have;
x + 10° = 2·x - 50°
Which gives;
2·x - x = 50° + 10° = 60°
x = 60°
Checking gives;
x + 10° = 2·x - 50° = 70°
Two angles of the first triangle are;
70° and 60°
The third angle of the first triangle is (180° - (70° + 50°)) = 60°
The three angles of the first triangle are therefore; 70°, 60° and 50°.
Two angles of the second triangle are;
70° and 50°
The third angle of the second triangle is (180° - (70° + 50°)) = 60°
The three angles of the second triangle are therefore; 70°, 60° and 50°
Therefore, the two triangles are similar by AAA similarity.
The two triangles are similar when, x = 60°When x = 50°, we have;
x + 10° gives;
50° + 10° = 60°
∴ ∠(x + 10°) = 60°
The two angles of the first triangle are; 60° and 50°
The third angle on the second triangle is 180° - (60° + 50°) = 70°
On the second triangle, we have;
2·x - 50° gives;
2 × 50° - 50° = 50°
∴∠(2·x - 50°) = 50°
Therefore, the two angles of the second triangle are; 50° and 50°
The third angle on the second triangle is 180° - (50° + 50°) = 80°
Therefore, the two triangles are not similar when x = 50°
Similarly, the two triangles are not similar when x + 10° = 50°
Therefore;
The possible value of x which the two triangles are similar is x = 60°

If you know that a < b, and both a and b and positive numbers, then what just be true about the relationship between the opposites of these numbers? Explain.
Answer:
-a > -b
Step-by-step explanation:
On a number line, every number (except zero, the origin) has both a magnitude and a direction (left or right, negative or positive).
The magnitude is how far the number is from the origin. 10 is further from zero than 6 is. And -10 is alos further from zero than -6 is.
If a < b and a,b are both positive, that means a and b are both on the right-hand side of the number line, and a is closer to the origin than b. The magnitude of a is smaller than that of b.
So if we switch the sign son both a and b, they both become negative and go over to the left-hand side of the number line. But their magntidues do not change, so a is still closer to the origin than b. Since b is now a negative number, further to the left than a, it is smaller than a.
Example: let a = 3 and b =5.
It is true that 3 < 5.
But it is NOT true that -3 < -5. It's the other way around!
-5 < -3
So, if a < b, then -a > -b.

For a normal distribution, what z-score value separates the lowest 25% of the scores from the rest of the distribution
Answer:
Z = -0.675.
Step-by-step explanation:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
What z-score value separates the lowest 25% of the scores from the rest of the distribution
This is Z which has a pvalue of 0.75, so Z = -0.675.
