If the circumference of a circle measures 3 4 π cm, what is the area of the circle in terms of π?
Answer:
Step-by-step explanation:
Answer:
289πStep-by-step explanation:
Circumference and area formulas
C = 2πrA = πr²Given
C = 34πFind r:
2πr = 34πr = 34π/2πr = 17Find the area:
A = πr² = π(17²) = 289πFind the midpoint of A and B where A has coordinates (-3,-5) and B has coordinates (4,4).
Brainliest if you want :)
Use the midpoint formula,
[tex]\left( \dfrac{x_1+x_2}{2} , \dfrac{y_1+y_2}{2} \right)[/tex]
where x₁ = -3, x₂ = 4, y₁ = -5, and y₂ = 4.
[tex]\left( \dfrac{x_1+x_2}{2} , \dfrac{y_1+y_2}{2} \right) \implies \left( \dfrac{-3+4}{2} , \dfrac{-5+4}{2} \right) = \left(0.5, -0.5\right).[/tex]
So, the midpoint of A and B is (0.5, -0.5). It should be in the first quadrant.

carlos es un arquitecto y esta construyendo una casa si ha construido 3/7 de la casa le falta para acabarla es lo mismo que llegar a 7/7
Answer:
Ok, sabemos que Carlos ha construido un 3/7 de una casa.
Queremos saber cuanto le falta para terminar de construirla.
Entonces podemos realizar el cálculo:
1 casa - lo que Carlos ya construyo = Lo que le falta.
Entonces:
1 casa - 3/7 de una casa = X
Podemos reescribir:
1 casa = 7/7 de una casas
así tenemos:
7/7 de una casa - 3/7 de una casa = X
(7/7 - 3/7) de una casa = X
4/7 de una casa = X
Así podemos concluir que a Carlos le falta construir 4/7 de una casa para acabar.
After substituting, what is the first step when evaluating
4y+9
____
7 when Y = 87
Answer:
The "first step" is the multiplication of 4 and 87
Step-by-step explanation:
I'll assume that you actually meant 4y + 97. If you substitute 87 for y, you get 4(87) + 97. The "first step" is the multiplication of 4 and 87:
348 + 97, or

A car is traveling at an average speed of 80km/h.What is it's speed in meters per second (m/s)
Answer:
22.21 m/s
Step-by-step explanation:
1 hour = 80km
1 minute = 80000 ÷ 60 = 1.333km
1 second = 1.333 ÷ 60 = 22.21
Log 8 1/32 is equaled to
Answer:
I think the answer wold be -5/3 or -1.666666667 .
The value of the given expression is,
[tex]log_8 \frac{1}{32}[/tex] = -3/5
The given logarithmic expression is,
[tex]log_8 \frac{1}{32}[/tex]
Since we know that,
The power to which a number must be increased in order to obtain additional values is referred to as a logarithm. The easiest approach to expressing enormous numbers is this manner. Numerous significant characteristics of a logarithm demonstrate that addition and subtraction logarithms may also be represented as multiplication and division of logarithms.
We can write the given expression as,
[tex]log_8 \frac{1}{32}[/tex] = [tex]log_8 32^{-1[/tex]
= - [tex]log_8 32[/tex] [ [tex]log_a b^x = x log_a b[/tex]]
= - [tex]log_{2^3} 2^5[/tex]
= - [tex]\frac{3}{5} log_{2} 2[/tex] [ [tex]log_{a^y} b^x = \frac{x}{y} log_a b[/tex]]
= -3/5 [ [tex]log_{a} a = 1[/tex]]
Hence,
[tex]log_8 \frac{1}{32}[/tex] = -3/5

please show work
Answer:
Step-by-step explanation:
The pentagon faces are made up of five triangle each with 9 ft bases and 6.2 ft heights. And there are five rectangular sides of 9 by 5 feet. So the total surface area is
A=2*5*9*6.2/2+5*9*5
A=279+225
A=504 ft^2
Answer:
Formula: nl(b + h) it is derived as well
504 ft²
Step-by-step explanation:
Each vertical face is a rectangle.
Area of each face = length x breadth = lb
For n-sided polygon, area of vertical faces = n x lb = nlb
For horizontal faces:
Observe: you can actually divide that face in 5 right-angled triangle(two edge point & centre form right angled ∆). [For n-sided, that's n right angled ∆]
For 2 such faces, you have 2 x n times of area of 1 ∆.
Area of 2n∆ = 2n( ½ x h x base(length)) = nhl
Total area = area of horizontal surfaces + area of vertical surfaces
Total area = nlb + nhl = nl(b + h)
Total area = 5*9(5 + 6.2) = 504 ft²
For a field trip 29 students rode in cars and the rest filled seven how many students were in each bus if 379 students were on the trip?
Answer:
50 students per bus
Step-by-step explanation:
You would need to subtract 29 from 379. You would get 350, then divide by 7.

What is the area of this rectangle?
544500 ......... is the answer
Answer:
The area of the rectangle is 544, 500 cm^2 or 54.45 m^2. (It depends on the requested unit—in cm squared or meters squared.)
Step-by-step explanation:
Area of a rectangle = length * width
A = 990 cm * 550 cm
A = 544, 500 cm^2
A = 54.45 m^2

Pls help me solve for x. And thank you so much
Answer:
x=11
Step-by-step explanation:
given -2 + 4x = 6(x-4) the objective is to get the variable (x) on one side and the constant on the other using inverse operations
-2 + 4x = 6(x-4)
step 1 distribute the 6 to x and -4
6*x=6x
6*-4=-24
now we have
-2 + 4x = 6x - 24
step 2 add 24 to each side
-2+24=22
-24+24 cancels out
now we have 22+4x=6x
now we want to get rid of the 4x
to do so we subtract 4x from each side
4x-4x cancels out
6x-4x=2x
now we have
2x = 22
step 4 divide each side by 2
22/2=11
2x/2=x
we're left with x = 11

Erica has 1 5/8 cups of yogurt to make smoothies. Each smoothie uses 1/3 of a cup of yogurt. What is the maximum number of smoothies that Erica can make with the yogurt?
Answer:
4 smoothies.
Step-by-step explanation:
We divide 1/3 into 1 5/8 ( which is 13/8).
= 13/8 / 1/3
= 13/8 * 3
= 39/8
= 4 7/8
Maximum number = 4.
