Answer:
Option F, 10 inches.
Step-by-step explanation:
For a circle of radius R, the perimeter is:
P = 2*pi*R
such that pi = 3.14
If we have a section of that circle defined by an angle θ, the length of the arc is:
A = (θ/360°)*P = (θ/360°)* 2*pi*R
In this case, we have a circle whose radius is defined by the length of the windshield wiper.
We also know that in one 90° revolution (so it travels the length of the arc of 90° two times) the tip travels a distance of 31 in.
Then:
A = 2*[(90°/360°)*2*3.14*R] = 31in
We need to solve this for R.
R = 31in/( 2*(90°/360°)*2*3.14) = 9.8in
We can round this to the next whole number:
R = 10in
The correct option is F.

C. 700 units.
The formula for the surface area of a rectangular prism is: 2 ((Width × Length) + (Height × Length) + (Height × Width))
(14 × 12) + (7 × 12) + (7 × 14)
168 + 84 + 98 = 350
Now do 350 × 2 = 700
700 units squared.
simon will deposit $250 into two savings accounts. account 1 earns 1.6% interest compounded annually. account 2 earns 1.6% simple annual interest. if simon makes no additional deposit or withdrawals, which account is closest to the difference in the interest that the account will have earned at the end of 10 years. A. $253.01 B.$43.01 C.$83.01 D.$3.01
The difference in the interest that the account will have earned at the end of 10 years is of:
D. $3.01.
What is the account 1 interest earned?The amount of interest earned, in compound interest, after t years, is given by:
[tex]I(t) = P\left(1 + \frac{r}{n}\right)^{nt} - P[/tex]
In which the variables are listed as follows:
P is the principal.r is the interest rate, as a decimal value.n is the number of times that interest is compounded per year, annually n = 1, semi-annually n = 2, quarterly n = 4, monthly n = 12.In the context of this problem, these parameters are given as follows:
P = 250, r = 0.016, n = 12, t = 10.
Hence the interest earned by account 1 is:
[tex]I(10) = 250\left(1 + \frac{0.016}{12}\right)^{12 \times 10} - 250 = 43.35[/tex]
What is the account 2 interest earned?For simple interest, the amount of interest earned is:
I(t) = Prt.
Hence:
I(10) = 250 x 0.016 x 10 = 40.
Hence the difference is:
43.35 - 40 = $3.35.
Which is closest to option D.

we are told that ∠ABD = 61°
then we also know that ∠ADB = 61° b/c there are the equal legs of an isosceles triangle.
and we know by inspection that the ΔBCD is identical to ΔABD so it also has 61° angles so
∠ABC = 61 + 61 =122°

El tamaño de cierto cultivo de bacterias se multiplica por 2 cada 30 minutos. Si suponemos que el cultivo tiene inicialmente 256 de bacterias, ¿Cuántas bacterias habrá transcurridas 3 horas? Cree un modelo matemático y exprese su respuesta como una potencia
Answer:
La población de bacterias después de tres horas es de [tex]2^{14}[/tex] bacterias.
Step-by-step explanation:
En este enunciado observamos un caso de progresión geométrica, en donde la población de bacterias se duplica cada treinta minutos, es decir:
[tex]\frac{p(n\cdot\Delta t)}{p(0)} = 2^{n}[/tex] (1)
Donde:
[tex]\Delta t[/tex] - Intervalo de tiempo requerido para el incremento geométrico de la población, en minutos.
[tex]n[/tex] - Número de períodos para incremento geométrico, sin unidad.
Sabemos que la población inicial de bacterias es 256 y que 3 horas son 6 veces 30 minutos. Entonces, tenemos la siguiente razón:
[tex]\frac{p(6\cdot \Delta t)}{p(0)} = 2^{6}[/tex] (2)
Si sabemos que [tex]p(0) = 256[/tex], entonces [tex]p(6\cdot \Delta t)[/tex] es:
[tex]p(6\cdot \Delta t) = 2^{6}\cdot p(0)[/tex]
[tex]p(6\cdot \Delta t) = 2^{6}\cdot (256)[/tex]
[tex]p(6\cdot \Delta t) = 2^{6}\cdot 2^{8}[/tex]
[tex]p(6\cdot \Delta t) = 2^{14}[/tex]
La población de bacterias después de tres horas es de [tex]2^{14}[/tex] bacterias.

Find the areas of a circle whose diameter is 21 cm
Answer:
Your answer is 346.36059
Step-by-step explanation:
A = pi*r²
A = pi * 10.5²
A = pi * 110.25
A = 346.36059
We can write the the area of the circle as 110.25π square centimeter.
What is Area?Area is a collection of two - dimensional points enclosed by a single dimensional line. Mathematically, we can write -
V = ∫∫F(x, y) dx dy
Given is a circle whose diameter is 21 cm.
It is asked to find the area of a circle whose diameter is 21 cm.
It is given that the diameter of the circle is -
d = 21 cm
r = d/2 = 21/2
r = 10.5 cm
We know that the area of the circle as -
Area = πr²
Area = π x 10.5 x 10.5
Area = 110.25π
So, it can be concluded that the area of the circle is 110.25π square centimeter.
Therefore, we can write the the area of the circle as 110.25π square centimeter.
