Answer:
5/6 hours
Step-by-step explanation:
Create a proportion where x is the number of hours it will take to walk 1/6 of a mile:
[tex]\frac{1/5}{1}[/tex] = [tex]\frac{1/6}{x}[/tex]
Cross multiply and solve for x:
1/5x = 1/6
x = 5/6
So, it will take the tortoise 5/6 hours to walk 1/6 of a mile
3. If a + b = C, which of the following statements is true?
Answer:
first one
Step-by-step explanation:
a + b = c
subtract a from both sides
b = c - a
or
c - a = b
[tex]\longrightarrow{\green{ a. \: c - a = b }}[/tex]
[tex]\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\red{:}}}}}[/tex]
[tex]a + b = c[/tex]
[tex]⇢ b = c - a[/tex]

Un microempresario realiza una inversión donde le pagan una rentabilidad del 5,36% mensual simple, él desea que esa inversión se triplique ¿Cuánto tiempo deberá esperar para que esto ocurra?
Answer:
Deberá esperar 37.31 años para que esto ocurra.
Step-by-step explanation:
Este es un problema de interés simple.
La fórmula del interés simple viene dada por:
[tex]E = P*I*t[/tex]
En el que E es la cantidad de interés ganado, P es el principal (la cantidad inicial de dinero), I es la tasa de interés (anual, como decimal) y t es el tiempo.
Después de t años, la cantidad total de dinero es:
[tex]T = E + P[/tex]
5,36% mensual simple
Esto implica que [tex]I = 0.0536[/tex]
Inversión se triplique ¿Cuánto tiempo deberá esperar para que esto ocurra?
Tiempo t para que la cantidad de interés sea lo doble de la cantidad inicial, o sea, [tex]E = 2P[/tex].
[tex]E = P*I*t[/tex]
[tex]2P = P*I*t[/tex]
[tex]It = 2[/tex]
[tex]0.0536t = 2[/tex]
[tex]t = \frac{2}{0.0536}[/tex]
[tex]t = 37.31[/tex]
Deberá esperar 37.31 años para que esto ocurra.
What are the coordinates of the point on the directed line segment from ( − 10 , 2 ) (−10,2) to ( − 10 , − 5 ) (−10,−5) that partitions the segment into a ratio of 6 to 1?
Answer: [tex](-10,-4)[/tex]
Step-by-step explanation:
Given
The points joining line segment are (-10,2) and (-10,-5)
Using section formula, a point joining segment [tex](x_1,y_1)\ \text{and}\ (x_2,y_2)[/tex] divides it in k:1 has coordinates
[tex]x=\dfrac{kx_2+1\cdot x_1}{k+1}[/tex], [tex]y=\dfrac{ky_2+y_1}{k+1}[/tex]
Ratio is 6:1
Coordinates are
[tex]\Rightarrow x=\dfrac{6(-10)+(-10)}{6+1}\\\\\Rightarrow x=-10[/tex]
[tex]\Rightarrow y=\dfrac{-5(6)+1(2)}{6+1}\\\\\Rightarrow y=\dfrac{-28}{7}\\\\\Rightarrow y=-4[/tex]
Thus, the coordinates are [tex](-10,-4)[/tex]

Work out the sum of 1/4 1/6 and 1/3
Answer:
[tex]\frac{3}{4}[/tex]
Step-by-step explanation:
[tex]\frac{1}{4} +\frac{1}{6} +\frac{1}{3}[/tex]
4 = 2 × 2 × 1
6 = 2 × 3 × 1
3 = 3 × 1

Square P and Square Q are similar squares. The ratio of the side length of Square P to the side length of Square Q is 2:7. If the side length of Square P is 3.5 inches, the perimeter of Square Q is?
Answer:
49 inches
Step-by-step explanation:
since we are talking about squares, and each side in a square has the same length, and all 4 angles are 90 degrees, "similar" did not mean much. every square is similar to every other possible square.
they all are bigger and smaller copies of themselves.
but how much bigger ?
in our case here P is the smaller square and Q the bigger one.
x = side length of P = 3.5"
y = side length of Q
x/y = 2/7
3.5/y = 2/7
7×3.5 = 2y
y = 3.5×3.5 = 12.25"
the perimeter of Q is
4×y = 4×12.25 = 49"
Find the sum of the series

Answer:
Find the indicated sum for each geometric series.
{1875+750+300+⋯+3.072}
Answer: 3122.952
Step-by-step explanation:
{1875+750+300+⋯+3.072}
r=0.4 3.072=1875(0.4)n−1
0.0016384=(0.4)n−1
7=n−1→n=8
Sn=1875(1−(0.4)8)1−0.4=3122.952

Fill in the blank with <,> or = . 11.01-----11.001
Answer: Greater than sign
In other words, 11.01 > 11.001
========================================================
Explanation:
For each given number, move the decimal point 3 spots to the right.
The value 11.01 becomes 11010
The value 11.001 becomes 11001
Since 11010 > 11001, this means 11.01 > 11.001

As an alternative method, you can subtract the values to see which is larger
The rule or idea is that
(large) - (small) = positive(small) - (large) = negativeFor example, 5-2 = 3 showing that 5 is larger than 2. As another example, 7-9 = -2 meaning 7 is smaller than 9. The order of subtraction matters.
In this case, 11.01 - 11.001 = 0.009 showing that 11.01 is larger than 11.001
An angle measuring 60 degrees is measured as 62 degrees. What is the percentage error correct to 3 significant figures?

In the cafeteria tables are arranged in groups of 4, with each table seating 8 students. How many students can sit at 10 groups of tables?
In a right triangle, Sin (4x + 10) º = Cos (6x) º. What is the value of x?
Answer:
Step-by-step explanation:
These angles will be equal when each of them measures 45 degrees. On the unit circle, 45 degrees and reference angles of 45 degrees are the only places where sin and cos are the same. This means that
sin(4x + 10) = 45 and cos(6x) = 45
If we add the angles together (the angles being 4x+10 and 6x) we get a 90 degree angle. Thus,
4x + 10 + 6x = 90 and
10x = 80 so
x = 8. Let's try it out:
sin(4(8) + 10) = sin(42) = .6691306064 and
cos(6(8)) = cos(48) = .6691306064

Answer:
If cashews cost $5.60 per pound and peanuts cost $2.30 per pound, how many pounds of each must he mix?
Step-by-step explanation:
Weegy: x + y = 1 (we want one pound total) 5.60 * x + 2.30 * y = 3.29 (we want 3.29 per pound) Answer: x = . 3, y = . 7 per one pound To get 10 pounds: cashews - 10x = 3 pounds, peanuts - 10y = 7 pounds.Type the correct answer in each box.

Answer:
26.4
Step-by-step explanation:
hd hd hd hd hd hd hd hd hd hd hd hd
Answer:$61.6
Step-by-step explanation: The sale is 30% so we have to look for 70% of $88 because that's what we're paying for. So, that would be 88 times 70/100 which ends with 61.6.
