Answer:
35 cm
Step-by-step explanation:
Perimeter is the sum of all edges of the given figure.
Given: the perimeter of the base of the regular triangular pyramid is P = 16.5 cm and the perimeter of a lateral face is 18.5 cm.
To find: sum of all edges of this pyramid
Solution:
sum of all edges of this pyramid = perimeter of the base of the regular triangular pyramid + perimeter of a lateral face = 16.5 + 18.5 =35 cm
Answer:
B. 3.4 pizzas.
Step-by-step explanation:
We have been given a scatter plot, which represents the number of pizzas (y) sold during weeks when different numbers of coupons (x) were issued. The equation represents the linear model for this data:
We can see that our given equation is in form of slope intercept form: , where m= slope of line and b = y-intercept.
We can see from our given equation that y-intercept is 43, when no coupons were issued, there were 43 pizzas sold. 43 is constant and it will not change by any change in x.
The slope of our line is 3.4, which represents change in number of pizzas with respect to change in number of coupons issued. Therefore, 3.4 more pizzas are sold for additional coupon issued and option B is the correct choice.
I am not 100 percent sure but i think you multiply and the answer is 7.75 if not then try to divid how you get 7.75 is you make 3/4 into a decimal and that becomes 0.75 them multiply by 10 and get 7.75
Answer: 9 textbooks
Step-by-step explanation:
25 x 120.00 = 3,000
4,000 - 3,000 = 1,000
9 x 105.00 = 945
1,000 - 945 = 55

Answer:
a = 4
b = 2√3
Step-by-step explanation:
Here, we want to get the missing side lengths
We start by looking at the values that we are given
from the question, a faces the right-angle and is called the hypotenuse; it is also the longest side
b faces the angle given and is also called the opposite
Lastly, the side marked 2 is the adjacent side
Now, the triangle given is called a 30-60-90 triangle
In a 30-60-90 triangle, the ratio of the sides are given as
1: √3:2
Thus, we have 1 as the adjacent
The opposite would be √3 * 2 = 2 √3 = b
Lastly , a = 2 * 2 = 4
