Answer:
43.30cm²
Step-by-step explanation:
Use Herons formula
S = (a+b+c)÷2
Where a, b, c is the sides of the triangle
If perimeter is 30cm
Since it's an equilateral triangle, all sides are equal.
Then
Perimeter = 3a = 30
a = 30/3 = 10cm
b = 10cm , c = 10cm
Therefore ,s= (10+10+10)÷2 = 30÷2 = 15cm
From Herons formula
Area = square root of s(s-a)(s-b) (s - c)
Area = sq rt 15(15 - 10)(15 - 10)(15 - 10)
Area = sq rt 15.× 5 × 5 ×5
Area = sq rt 1875
Area = 43.30cm²

Answer:
≈ 43.3 cm²
Step-by-step explanation:
The area (A) of an equilateral triangle is calculated as
A = ( s is the side length )
The 3 sides of an equilateral triangle are congruent, thus
s = 30 ÷ 3 = 10 cm
A = =
= 25
≈ 43.3 cm²
Answers
Answer:
C. 50
Step-by-step explanation:
Here we have to look at the given graph and find the answer.
The vertical axis represents the price and cost per unit. That is represented by P.
The horizontal axis represents the units of output, that is represented by q.
We need to find the number of units when p = $55.
By look at the graph of the curve MC, when P = $55, the number of units is 50.
Therefore, the answer is C. 50.
Hope this will helpful to understand the concept.
Thank you.

Taking the first case of Kylie we get that he drank 35% water of 400ml
Then
35% of 400 ml = (35/100) * 400 ml
= (35 * 4) ml
= 140 ml
So Kylie drank a total of 140 ml water.
Now taking the case of Eugenia we get that he drank 45% of 350 ml water.
Then
45% of 350 ml = (45/100) * 350
= 1575/10 ml
= 157.5 ml
So Eugenia drank 157.5 ml of water. Then we can conclude that Eugenia drank more water than Kylie.
Answer: Eugenia, 17.5

the odd number is 3
aka you can't divide it y 2 niccley
10/2=5
8/2=4
3/2=nastynumber
4/2=2
odd is 3
10/2 = 5
8/2 = 4
3/ 2 = 1 1/2
4/2 = 2
therefore, 3 is the odd number.

According to the model, how many more pizzas are sold for each additional coupon issued?
1 pizzas
3.4 pizzas
4.3 pizzas
43 pizzas
46 pizza
Answers
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.
