Answer:
I am assuming you meant that the old machine made 248 toys in one hour instead of both if that is the case then the answer would be 744.
Steph-by-step explanation:
The new machine makes three times as many as the old machine so 248 times 3 = 744 toys in one hour
Answer:
Step-by-step explanation:
Given is the hexagonal pyramid.
We know the radius of the base is same as its side.
<u>Find the base area:</u>
- A = 3√3/2a²
- A = 3√3/2*6² = 54√3
<u>Given the height and radius, find the side of the lateral triangular faces:</u>
Each of 6 triangles have sides 10, 10 and 6 units.
<u>Find the area using heron's formula:</u>
- s = P/2 = (10*2 + 6)/2 = 13
- s - a = s - b = 13 - 10 = 3
- s - c = 13 - 6 = 7

<u>Total surface area:</u>
Correct choice is B
The zeroes are
0, -5, 3 + i (and its conjugate)
The factors are
x (x + 5) (x - (3 + i)) (x - (3 - i))
Expanding...
(x² + 5x)((x - 3) - i) ((x - 3) + i)
(x² + 5x)((x - 3)² - i²)
(x² + 5x)(x² - 6x + 9 - (-1))
(x² + 5x)(x² - 6x + 10)
x⁴ - 6x³ + 10x² + 5x³ - 30x² + 50x
x⁴ - x³ - 20x² + 50x
The expressions that could represent how much Leila pays in total for the model
\dfrac{107}{100}x
100 107 Option A is correct.
This is further explained below.
<h3>Which of the following expressions could represent how much Leila pays in total for the model?</h3>
The price of the model is x
Now we are given that she also has to pay a 7 tax.
Amount of tax =7 % x

the Total cost

In conclusion, the statement might signify Leila's overall cost for the model.

Act like it's a rectangle. The height is 10 because 7+3=10 and the length it 27. Multiply them for the are and you get 270 in. Then multiply 6x7=42 because that's the are of the space that is missing from the imaginary rectangle. Multiply by 2 (84 in.) because there are 2 missing spaces and subtract from 270= 186 inches is your answer.
