Answer:
17a + 16 =
Step-by-step explanation:
Add all a's
then all numbers w/o letters
you cannot add them together bc it would be like adding apples to carrots (thats what my teacher said)

Answer:
107/18
Step-by-step explanation:
Your calculator and/or knowledge of trig function values can help you evaluate this.
= 4/3(1/3) +3/4 -3(3/4) +3(3) -2(1)
= 4/9 +3/4 -9/4 +9 -2
= 107/18
___
tan(30°) = 1/√3
tan(45°) = 1
tan(60°) = √3
sin(60°) = cos(30°) = √3/2
Answer:
- small prism: 630 m²
- large prism: 2520 m²
Step-by-step explanation:
The total surface area of the prism is the sum of the base area and the lateral area. The base area is made up of two right triangles, so will be the product of the triangle leg dimensions. The lateral area is made up of three rectangles whose width is that of the prism and whose equivalent length is the perimeter of the triangle base.
For the smaller prism, the area is ...
(20 m)(21 m) +(3 m)(20 m + 21 m + 29 m) = 420 m² +210 m² = 630 m²
The larger prism is similar, with a scale factor of 2, so its area will be 2² = 4 times that of the smaller prism:
4×630 m² = 2520 m²
__
In summary, the total surface area of each prism is ...
- small prism: 630 m²
- large prism: 2520 m²
Answer:
$58.9
Step-by-step explanation:
In this question, we're going to go step by step to get the final price of the share.
We know that the stock started off as $60 per share, so that would be our starting value.
The stock dropped by 20%, so let's calculate the drop in price.
60 • 0.20 = 12
60 - 12 = 48
On Monday, the value of the stock was $48
On Tuesday, the stock dropped by $10, so calculate that drop as well
48 - 10 = 38
On Tuesday, the stock value is at $38
The stock increased by 55%, so we need to calculate the increase.
38 • 1.55 = 58.9
This means that the final price of the share was $58.9
Answer:
12.7
Step-by-step explanation:
Mean is total/the amount of numbers
Total: 11+14+11+5+17+28+3=89
Amount: 7
89/7=12.7142857
