Sasha's grandma is going to sew this umbrella for Sasha. The umbrella is made of 4 identical triangles. If each triangle is 3 feet long and 4 feet high, how many square feet of fabric does Sasha's grandma need? Explain how you found your answer.
Answer:
Sasha's grandma will need 48 square feet of fabric to sew the umbrella.
Step-by-step explanation:
Since Sasha's grandma is going to sew an umbrella for Sasha, which will be made of 4 identical triangles, if each triangle is 3 feet long and 4 feet high, to determine how many square feet of fabric does Sasha's grandma need, the following calculation must be done:
(3 x 4) x 4 = X
12 x 4 = X
48 = X
Therefore, Sasha's grandma will need 48 square feet of fabric to sew the umbrella.
You are watching fireworks over San Diego Bay S as you sail away in a boat. The highest point the fireworks reach F is about 0.2 mile above the bay. Your eyes E are about 0.01 mile above the water, the lowest elevation from which you see the fireworks above your horizon. (At point B you cannot see the fireworks because of the curvature of Earth.) The radius of Earth is about 4000 miles, and FE¯¯¯¯¯¯¯¯ is tangent to Earth at point T. Find mSB⌢. Round your answer to the nearest tenth.
Based on the calculations, the measure of angle m<SB rounded to the nearest tenth is equal to 0.70°.
What is a tangent?In geometry, a tangent is also referred to as a tangent line and it can be defined as a straight line that touches a plane curve at a specific point.
Based on the diagram, we would apply the cosine function to determine the measure of the angle formed by the hypotenuse side of the triangle with respect to the radius of Earth (adjacent side):
m<SB = cos⁻¹(4000/4000 + 0.2) + cos⁻¹(4000/4000 + 0.01)
m<SB = cos⁻¹(4000/4000.2) + cos⁻¹(4000/4000.01)
m<SB = cos⁻¹(0.99995) + cos⁻¹(0.9999975)
m<SB = 0.573 + 0.128
m<SB = 0.701 ≈ 0.70°.

The triangle ΔBAD is congruent to the triangle ΔCDA by SSS postulates.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.
The ratio of the matching sides will remain constant if two triangles are comparable to one another.
If the corresponding sides of the triangles are equal. Then the triangles will be a congruent triangles. And it is known as SSS postulates.
BD = AC and AB = CD
In triangles ΔBAD and ΔCDA, we have
BD = AC (Given)
AB = CD (Given)
AD = AD (Common side)
Then the triangle ΔBAD is compatible with the triangle ΔCDA by SSS proposes.

Cyclone cleared leaves from the same number of yards each day for 5 days. Then on day 6, he cleared the leaves from 8 more yards. He cleared 133 yards in all.
How many yards did Cyclone clear the first day?
Answer:
20.83 yard
Step-by-step explanation:
Calculate Cubic Yards
Calculate your area
Calculate your volume: Multiply area times the depth to get volume in cubic feet
Calculate your cubic yards: Divide cubic feet by 27 to convert to cubic yards and this is your answer
Where ft2 = square foot, ft3 = cubic foot, yd3 = cubic yard
Total yards = 5[x] + x + 8
Solve
133 = 6x + 8
6x = 125
x = 20.83 yard
Therefore, the Cyclone cleared 20.83 yards on the first day.
If the simple interest on a sum of money at 5% per annum for 3 years is $
1200, then the compound interest on the same sum for the same period
at the same rate will be .........
*
Answer:
$1207.96
Step-by-step explanation:
The accumulated value for simple interest is defined by the following formula:
FV=PV(1+it)
we have (where x is the present value or PV)
1200= x(1+.05*3)
Solve for x
1200=1.15x
x=1043.478261
We now need to use the equation for annually compounding interest
[tex]FV=PV(1+i)^t[/tex]
We have
[tex]1043.4782(1+.05)^3\\1207.956522[/tex]
which rounds to
$1207.96

Una bacteria se divide en dos cada 6 minutos Si a las 12:15 horas se coloca una bacteria en un recipiente¿ A que hora habrá 128 bacterias en el recipiente?
Answer:
A las 12:57 horas habrá 128 bacterias en el recipiente.
Step-by-step explanation:
Una función exponencial es aquella en que la variable independiente x aparece en el exponente y tiene de base una constante a. Su expresión es:
f(x)= aˣ
Siendo a un real positivo, a > 0, y diferente de 1.
Cuando 0 < a < 1, entonces la función exponencial es una función decreciente y cuando a > 1, es una función creciente.
Algunos tipos de bacterias se reproducen por "mitosis", dividiéndose la célula en dos cada espacios de tiempo pequeños, como sucede en este caso. Entonces, "a" tendrá un valor de 2, que es la cantidad en la que se divide la bacteria, y "x" será los intervalos de tiempo. Si hay 128 bacterias en el recipiente, la expresión exponencial del crecimiento de la bacteria en x intervalo de tiempo será:
2ˣ= 128
Una manera de resolver la x es aplicando logaritmos. Entonces, aplicando el logaritmo común de ambos lados. (Cuando la base no está escrita, se trata de la base 10):
log (2ˣ) = log (128)
Aplicando la propiedad de la potencia de los logaritmos:
x* log (2)= log (128)
x= log (128) ÷ log (2)
x= 7
Cada intervalo de tiempo tiene 6 minutos, que es el tiempo en que una bacteria se divide en 2. Entonces, el tiempo que se tarda en obtener 128 bacterias se calcula como:
7 intervalo* 6 minutos= 42 minutos
Si a las 12:15 horas se coloca una bacteria en un recipiente, entonces el horario a la que habrá 128 bacterias se calcula como:
12:15 + 42 minutos= 12:57
A las 12:57 horas habrá 128 bacterias en el recipiente.

Is the relationship between the variables a direct variation, an inverse variation or neither? If there is a variation write the function rule, where x is 2,3,4,5 y = 9,6,4.5,3.6
Answer:
Indirect variation
Rule: [tex]y = \frac{18}{x}[/tex]
Step-by-step explanation:
Given
[tex]x \to 2,3,4,5[/tex]
[tex]y \to 9,6,4.5,3.6[/tex]
Required
Determine the type of variation
For direct variation, we have:
y increases, as x increases
In the above function, y decreases, as x increases
Hence, it is not a direct variation
Indirect variation.
In an indirect variation, y decreases, as x increases
And the equation is given as:
[tex]y = \frac{k}{x}[/tex]
Make k the subject
[tex]k =xy[/tex]
Where k is the constant of variation.
For:
[tex](x,y) = (2,9)[/tex]
[tex]k = 2 * 9 = 18[/tex]
For:
[tex](x,y) = (3,6)[/tex]
[tex]k = 3 * 6 = 18[/tex]
For every other values;
[tex]k = x * y = 18[/tex]
Hence, it is an indirect variation.
The rule is:
[tex]y = \frac{k}{x}[/tex]
Substitute 18 for k
[tex]y = \frac{18}{x}[/tex]
