Answer:
Area = 12 + 6.25π ft², Perimeter = 6 + 5π ft
Step-by-step explanation:
Area:
So I would break this shape into a triangle and a circle (the two semi-circles make a full circle).
Formula for Area of a Triangle: base · height ÷ 2
6 · 4 ÷ 2 = 24 ÷ 2 = 12
Formula for area of a circle: π · radius²
π · (5/2)² = 6.25π
Area of entire shape: Triangle + Circle
Area = 12 + 6.25π ft²
Perimeter:
So the perimeter is made up of the base of the triangle plus the circumference of the circle.
Base of Triangle: 6
Formula for circumference: 2rπ
5 · π = 5π
Perimeter = 12 + 5π ft

Well, we know that 6 * 4 = 24
So, we will be multipying the numerator and denominator with 4/4:
[tex]\frac{3}{6}=\frac{3*4}{6*4}=\frac{12}{24}[/tex]

Cual es la formula para calcular la masa de los atomos de carbono y nitrogeno?
POR FAVOR Y DOY CORONA Y CORAZON
Answers
Answer:
La masa atómica del carbono (C) es 12 g/mol; para el oxígeno (O) es de 16 g/mol. Esto significa que 6.022 x 1023 átomos de carbono pesan 12 gramos. Según esto, el peso molecular del CO2 es: 12 g/mol [C] + 2 x 16 g/mol [O2] = 44 g/mol.
1 molécula de Nitrógeno por su masa atómica de 14.01 más 3 moléculas de Hidrógeno por su masa atómica de 1.008 = (1 * 14.01) + (3 * 1.008) = 14.01 + 3.024 = 43.038 u = 17.03 masa molecular = 17.03 g/mol de masa molar en el amoníaco.

A taxi company charges a flat fee of $3.50 per ride plus an additional $0.65 per mile. If Ian has only $10, what is the farthest he can ride?
Answers
Answer:
10 miles
Step-by-step explanation:
Before he goes anywhere there is a fee of $3.50. $10 - $3.50 = $6.50. If you divide $6.50 by $0.65 you can find how many miles he can ride. $6.50 divided by $0.65 = 10. That means Ian can ride the taxi for 10 miles.

Suppose A and B are independent events. The probability that event A will not occur is 0.1 and the probability that event B will occur is 0.7. Find P(A), P(not B) and P(A and B).
Answers
Answer:
The probability for A is 1-0.1 is 90%
P(A)=90%
P(NOT B)=30%
P(A AND B)=0.9+0.7/2=1.6/2=80%
p(a and b) may be a little off.
Answers:
P(A) = 0.9P(not B) = 0.3P(A and B) = 0.63=======================================================
Work Shown:
P(A) = 1 - P(not A)
P(A) = 1 - 0.1
P(A) = 0.9
-------------------
P(not B) = 1 - P(B)
P(not B) = 1 -0.7
P(not B) = 0.3
-------------------
P(A and B) = P(A)*P(B) only when A and B are independent
P(A and B) = 0.9*0.7
P(A and B) = 0.63

What area is the shape?
Answers
Answer:
20 Units
Step-by-step explanation:
The question wants us to find the area of the shape.
From looking at the shape, we can easily infer that it is made of 1 square and 1 triangle.
Area of a Square/Rectangle Formula: A = W(L)
Area of a Trangle Formula: A = (1/2)(b)h
A = W(L)+(1/2)(b)h
The base of the traingle can be found by subtracting the longer length (6) from the smaller length (4).
A = 4(4)+(1/2)(2)4
A = 16+(1)4
A = 16+4
A = 20 Units
Which expression is equivalent to the expression shown below?
-9.25(2n-3) - 8n
A. -18.5n + 19.75
B. 55.5n+ 27.75
C. 26.5n + 19.75
D. 27.75 -26.5n
Answers
Answer:
option D
Step-by-step explanation:
Distribute (-9.25) to 2n and (-3). When we multiply (-9.25) and 2n, we get -18.5n and when we multiply (-9.25) and (-3) we get 27.75.
-9.25(2n - 3) - 8n = -9.25*2n - (-9.25) *3 - 8n
= -18.50n + 27.75 -8n
= -18.5n - 8n + 27.75
Combine like terms. Here (-18.5n) and (-8n) are like terms
= -26.5n + 27.75

there are 3 sides on a triangle so do 50 x 3 = 150
now we need to find the area of the triangles
the formula for the surface area would be base x height ÷ 2
3 x 4 = 12
12 ÷ 2 is 6
because there are 2 triangles you would need to multiply it by 2
6 x 2 is 12
add it all together

I really need help with this
I will check to see if it right before giving points thank you.
Answers
Step-by-step explanation:
For the question question, since they are giving you the function you just need to find the input that matches the expected output (y) which will be the number of miles biked. So what numbers multiplied by 12 give you 12, 36, and 48?
You could substitute y into an algebraic function to find these values.
We'll use 36 miles as an example.
If 12x = y then
12x = 36
divide both sides by 12
x = 3
For the second question you are given the x value (number of guests) and just need to calculate y (cupcakes each guest is allowed) by dividing 30 by the number of guests (x).
